LASER AND CUTTING MACHINING APPARATUS

FIELD

The present application relates to the technical field of engraving and cutting, and in particular to a laser and cutter machining apparatus.

BACKGROUND

A laser and cutter machining apparatus uses laser as a processing medium to perform machining. Since the laser and cutter machining apparatus is not in direct contact with a workpiece, it is not affected by mechanical motion, and thus the surface of the workpiece is not easily deformed. When a user needs to machine workpieces to produce some complex handicrafts or other works, a conventional laser processing machine is generally required to be used in conjunction with a cutter processing machine. In the process of machining the workpiece by using the laser processing machines and the cutter processing machine, the user usually needs to separately operate the laser processing machine and the cutter processing machine to move up and down to machine the workpiece.

SUMMARY

In order to solve the above problems, a laser and cutter machining apparatus is provided according to the present application, which can improve machining accuracy.

A laser and cutter machining apparatus is provided according to the present application, which includes a laser and cutter device. The laser and cutter device includes a housing, a guide plain shaft, and a machining mechanism. The guide plain shaft is arranged in the housing. The machining mechanism includes a laser case slidably connected to the guide plain shaft, a laser arranged in the laser case, and a cutter mechanism arranged in the laser case. The laser and the cutter mechanism are configured to move relative to the housing along the guide plain shaft with the laser case.

Referring to FIGS. 1 to 3 together, a laser and cutter machining apparatus 100 for machining workpieces (not shown in the figures) is provided according to the present application. In the present application, the machining of workpieces by the laser and cutter machining apparatus 100 refers to performing operations such as cutting, engraving, or indentation on the workpieces, so that the workpieces after being machined meet the requirements of the user.

The laser and cutter machining apparatus 100 includes a support device 10, a rail device 20, and a laser and cutter device 40. The support device 10 is configured to support the rail device 20 and the laser and cutter device 40. The rail device 20 includes a first rail device 201 and a second rail device 203. The first rail device 201 is fixed to the support device 10. The second rail device 203 is movably arranged on the first rail device 201. The second rail device 203 is configured to move linearly in a first direction (direction Y as shown in FIG. 1) on the first rail device 201. The laser and cutter device 40 is movably arranged on the second rail device 203. The laser and cutter device 40 is configured to move linearly in a second direction (direction X as shown in FIGS. 1 and 2) on the second rail device 203. The first direction is different from the second direction. The laser and cutter device 40 includes a housing 41 movably arranged on the second rail device 203, a guide plain shaft 42 arranged in the housing 41, and a machining mechanism 50. The housing 41 is configured to move linearly in the second direction on the second rail device 203. The machining mechanism 50 is configured to move linearly in a third direction (direction Z1 as shown in FIGS. 1, 2, and 3) or in a fourth direction (direction Z2 as shown in FIGS. 1, 2, and 3) relative to the housing 41 on the guide plain shaft 42. The third direction is opposite to the fourth direction; the first direction, the second direction, and the third direction are different from one another; and the first direction, the second direction, and the fourth direction are different from one another. In this embodiment, the number of the first rail devices 201 is two, and the second rail device 203 is arranged on the two first rail devices 201 in a spanning manner. The machining mechanism 50 is configured for machining, the machining mechanism is able to approach the workpiece in the third direction to press against the workpiece, and the machining mechanism 50 is able to move away from the workpiece in the fourth direction. It can be understood that the support device 10 may be omitted.

The laser and cutter machining apparatus 100 may be disassembled into several modules. In particular, each of the first rail device 201, the second rail device 203, and the laser and cutter device 40 can be assembled into a complete module, which minimizes the assembly difficulty and the assembly time for the user, and ensures a good motion performance after the assembly is completed.

The support device 10 includes a support frame 11 and four foot pads 12. The four foot pads 12 are respectively fixed at positions of four corners of the bottom of the support frame 11 for raising the height of the laser and cutter machining apparatus 100. It can be understood that the number of foot pads 12 is not limited in the present application, which may be one or more. It can be understood that in some embodiments, the foot pad assembly 13 may be omitted.

Referring to FIGS. 3, 4, 5, 7, and 8 together, the laser and cutter device 40 includes the housing 41, the guide plain shaft 42, and the machining mechanism 50. The guide plain shaft 42 is fixedly arranged in the housing 41, and extends in the third direction. The machining mechanism 50 includes a laser case 51, a laser 52 arranged in the laser case 51, and a cutter mechanism 55 arranged in the laser case 51. The laser case 51 is slidably connected to the guide plain shaft 42, and the laser 52 and the cutter mechanism 55 can move, along with the laser case 51, in the third direction or the fourth direction relative to the housing 41. The laser 52 is configured to emit laser light to machine the workpiece.

The laser and cutter device 40 of the laser and cutter machining apparatus 100 integrates the laser 52 and the cutter mechanism 55 through the laser case 51, which not only can use the laser light as the processing medium to machine the workpiece through the laser 52, but also can use the cutter mechanism 55 as the processing medium to machine the workpiece. The tool complexity of operating the laser and cutter machining apparatus 100 is reduced, and the operation is simple and convenient. Moreover, the laser and cutter machining apparatus 100 guides the movement of the laser 52 and the cutter mechanism 55 relative to the housing 41 through the guide plain shaft 42, which improves smoothness and accuracy of the movement of the laser 52 and the cutter mechanism 55 relative to the housing 41, thereby ensuring the movement accuracy of the laser 52 moving towards the workpiece to an appropriate distance for machining the workpiece, and improving the machining accuracy of the laser and cutter device 40.

In the embodiment, the laser 52 may move along with the laser case 51 in the third direction (Z1 as shown in FIG. 3) relative to the housing 41 to approach and press against the workpiece. When the laser 52 moves in the third direction relative to the housing such that there is an appropriate distance between the laser 52 and the surface of the workpiece in the third direction, the laser 52 may emit laser light to machine the workpiece. The laser 52 can move along with the laser case 51 in the fourth direction (Z2 as shown in FIG. 3) relative to the housing 41 to move away from the workpiece.

In the embodiment, the number of the guide plain shafts 42 is two, and both the axes of the two guide plain shafts 42 are parallel to the third direction, and the two guide plain shafts 42 do not coincide. The laser case 51 moves synchronously on the two guide plain shafts 42 when the laser case 51 moves relative to the housing 41. It can be understood that in another embodiment, the number of the guide plain shaft 42 may be a positive integer which is at least one, such as at one, three or four.

Referring to FIGS. 3 to 5, 7, 10, and 11 together, the housing 41 is provided with a connecting portion 411 corresponding to the guide plain shaft 42. The connecting portion 411 is provided with a connecting hole 4111, and an end of the guide plain shaft 42 is inserted into the connecting hole 4111. In this way, the guide plain shaft 42 is fixedly connected to the housing 41 through the connecting hole 4111 of the connecting portion 411. The laser case 51 slides on the guide plain shaft 42 in the third direction or the fourth direction, which is equivalent to that, the laser case 51 moves in the third direction or the fourth direction relative to the housing 41. In addition, the connecting portion 411 has a limiting function, that is, the laser case 51 presses against or is in contact with the connecting portion 411 when the laser case 51 slides by a certain distance in the fourth direction on the guide plain shaft 42. At this time, the laser case 51 cannot keep sliding in the fourth direction on the guide plain shaft 42.

In the embodiment, the number of the connecting portions 411 is two, and the two connecting portions 411 are in one-to-one correspondence with the two guide plain shafts 42. Each of the connecting portions 411 is provided with the connecting hole 4111, and the ends of the two guide plain shafts 42 are respectively inserted into the connecting holes 4111 of the corresponding connecting portions 411.

In another embodiment, the number of the connecting portion 411 may be one, and the connecting portion 411 is provided with connecting holes 4111 that are in one-to-one correspondence with the two guide plain shafts 42, the ends of the two guide plain shafts 42 are respectively inserted into the corresponding connecting holes 4111, which is also within the protection scope of the present application.

In the embodiment, the connecting hole 4111 penetrates through two opposite end faces of the connecting portion 411 in the third direction. In another embodiment, the connecting hole 4111 may only penetrate through an end face of the connecting portion 411 facing the laser case 51.

In the embodiment, the connecting portion 411 is arranged in the housing 41, and the laser case 51 may penetrate into the housing 41 along the guide plain shaft 42 inserted in the connecting portion 411. In this way, the laser case 51 can be accommodated in the housing 41, which reduces the overall size of the laser and cutter device 40 and improves space utilization. Of course, the connecting portion 411 may alternatively be arranged outside the housing 41, that is, the laser case 51 cannot be accommodated in the housing 41.

In the embodiment, when the laser case 51 moves in the third direction or the fourth direction along the guide plain shaft 42 in the housing 41, there is a gap between the laser case 51 and an inner wall of the housing 41. In this way, the friction resistance between the laser case 51 and the housing 41 can be minimized when the laser case 51 moves in the third direction or the fourth direction along the guide plain shaft 42 in the housing 41, so that the movement of the laser 52 driven by the laser case 51 is smooth, and the control accuracy is high.

Referring to FIGS. 3 to 5, 7, and 10 together, the laser case 51 includes a guide portion 511 corresponding to the guide plain shaft 42, the guide portion 511 is provided a guide hole 5111 that penetrates through two opposite end faces of the guide portion 511 in the third direction, and the guide plain shaft 42 is movably inserted in the corresponding guide hole 5111. In this way, the laser case 51 is movable along the guide plain shaft 42 through the guide hole 5111. In this embodiment, the number of the guide portions 511 is two, and the two guide portions 511 are in one-to-one correspondence with the two guide plain shafts 42. Each of the guide portions 511 is provided with the guide hole 5111, and the two guide plain shaft 42 are movably inserted in the guide holes 5111 of the corresponding guide portions 511 respectively. In another embodiment, the number of the guide portion 511 may be one, and the guide portion 511 is provided with two guide holes 5111 that are in one to one correspondence with the two guide plain shafts 42, the two guide plain shafts 42 are movably inserted in the corresponding guide holes 5111, which is also within the protection scope of the present application.

In an embodiment, the laser case 51 is provided with a sleeve 44 fixedly arranged in the guide hole 5111, and the guide plain shaft 42 is movably inserted in the sleeve 44 in the corresponding guide hole 5111. With the sleeve 44, the smoothness and accuracy of the sliding of the guide plain shaft 42 in the guide hole 5111 are improved, and the smoothness and accuracy of the movement of the laser 52 relative to the housing 41 are further improved. Moreover, compared to a solution in which the guide plain shaft 42 is directly inserted in the corresponding guide hole 5111, i.e. no component is provided between the guide plain shaft 42 and the guide hole 5111, the sleeve 44 with a high precision is directly mounted and fixed in the guide hole 5111, which effectively reduces requirements of machining accuracy for the guide hole 5111. That is, the smoothness and accuracy are improved while the machining difficulty and costs are reduced. In this embodiment, the sleeve 44 is a copper sleeve. It can be understood that the sleeve 44 may also be made of other metals or materials.

Referring to FIGS. 3, 5 to 7, and 9 to 11 together, the laser and cutter device 40 further includes a driving assembly 45. The driving assembly 45 includes a driving member 451 arranged in the housing 41. The driving member 451 is configured to drive the laser case 51 to move along the guide plain shaft 42. In this way, under the action of the driving member 451, the laser case 51 can move in the third direction or the fourth direction relative to the housing 41.

Specifically, an outer peripheral wall of the guide portion 511 is provided with a rack 5112 extending in the third direction. The driving assembly 45 further includes a gear 452 connected to the driving member 451 and engaged with the rack 5112. The driving member 451 drives the gear 452 to rotate, so that the rack 5112 moves in the third direction or the fourth direction relative to the guide plain shaft 42. In this way, the driving member 451 can drive the laser case 51 to move on the guide plain shaft 42 through the engagement between the gear 452 and the rack 5112, so that the laser 52 can move along with the laser case 51 relative to the housing 41.

In this embodiment, the driving member 451 is a motor. The gear 452 is fixedly connected to a rotation shaft of the motor, that is, the gear 452 is fixedly sleeved on the rotation shaft. The gear 452 is coaxial with the rotation shaft. The gear 452 can rotate with the rotation shaft when the rotation shaft of the motor rotates, so that the rack 5112 can move in the third direction or the fourth direction relative to the guide plain shaft 42. When the rotation shaft of the motor does not rotate, the friction force between the gear 452 fixedly connected to the rotation shaft and the rack 5112 can play a locking role, so that the laser case 51 cannot move on the guide plain shaft 42, thereby limiting the movement of the laser case 51 relative to the housing 41. Thus, the position of the laser case 51 on the guide plain shaft 42 is locked.

In this embodiment, the outer peripheral wall of one of the two guide portions 511 is provided with the rack 5112 extending in the third direction, the number of the gear 452 is one, and the gear 452 is correspondingly engaged with the rack 5112. In another embodiment, the outer peripheral wall of each of the two guide portions 511 is provided with the rack 5112 extending in the third direction, the number of the gears 452 is two, the racks 5112 of the two guide portions 511 are correspondingly engaged with the gears 452, which is also within the protection scope of the present application.

In the embodiment, the rotation shaft of the motor (i.e., the driving member 451) is rotationally sleeved with a connecting member 453. The connecting member 453 is connected to the driving member 451, and the connecting member 453 is configured to connect the driving assembly 45 to the housing 41. Specifically, the connecting member 453 is provided with two first through holes 4531; a first fixing portion 412 extending in the third direction is provided in the housing 41, and the first fixing portion 412 is provided with a connecting groove 4121 extending in the third direction, two parts of the first fixing portion 412 respectively located on both sides of the connecting groove 4121 are each provided with a second through hole 4122; and the two second through holes 4122 are in one-to-one correspondence with the two first through holes 4531. The connecting member 453 is fixedly connected to the first fixing portion 412 by the accessories such as screws passing through the first through holes 4531 and the corresponding second through holes 4122, so that the driving member 451 is fixedly connected to the housing 41.

Referring to FIGS. 5 to 7, 13 and 14 together, the laser and cutter device 40 further includes a drive control assembly 46. The drive control assembly 46 includes a first control board 461 electrically connected to the driving member 451. The first control board 461 is configured to transmit a first control signal to the driving member 451, so as to control the driving member 451 to drive the laser case 51 to move in the third direction or the fourth direction relative to the housing 41. In this way, the first control signal sent by an external control center can be transmitted to the driving member 451 through the first control board 461, to control the rotation of the driving member 451 and further control the rotation of the gear 452 connected to the driving member 451, so as to control the laser case 51 to move in the third direction or the fourth direction relative to the housing 41. The external control center can control the movement distance of the laser case 51 on the guide plain shaft 42 by controlling the amount of the rotation of the driving member 451 through the first control signal, so as to control the movement distance of the laser case 51 in the third direction or the fourth direction relative to the housing 41, to ensure that the laser 52 can accurately move with the laser case 51 to a preset position relative to the housing 41, and thus the machining accuracy of the laser and cutter device 40 is improved.

The drive control assembly 46 further includes a reset sensor 462 arranged on the first control board 461, which is electrically connected to the first control board 461. The first control board 461 is connected to the housing 41, and the laser case 51 is provided with a reset member 53. The laser case 51 moves in the fourth direction until the reset member 53 cooperates with the reset sensor 462 to output a reset signal. The laser case 51 no longer moves in the fourth direction when the reset member 53 cooperates with the reset sensor 462 to output the reset signal. The external control center receives the reset signal through the first control board 461 and records current position information of the laser case 51 to determine an origin position of the laser and cutter device 40 in the third direction and the fourth direction. In this case, the external control center can output the corresponding first control signal based on the requirement of the user through precise algorithms, so as to control the movement distance of the laser case 51 in the third direction or the fourth direction relative to the housing 41, to ensure that the laser 52 and the cutter mechanism 55 can accurately move with the laser case 51 to the preset position relative to the housing 41, and thus the machining accuracy of the laser and cutter device 40 is improved. In this embodiment, the first control board 461 is fixed in the housing 41 through accessories such as screws, and the first control board 461 is positioned on the surface of the connecting portion 411 facing away from the laser case 51. In another embodiment, the first control board 461 may also be bonded to the connecting portion 411 and fixed in the housing 41 by gluing, welding, and the like.

In the embodiment, the reset sensor 462 is a groove-type optocoupler sensor. When the reset member 53 moves in the fourth direction with the laser case 51 and is inserted into a groove of the reset sensor 462, the reset member 53 can cooperate with the reset sensor 462 to output the reset signal. In an embodiment, when the laser case 51 moves in the fourth direction and contacts or presses against the connecting portion 411, the reset member 53 moves in the fourth direction with the laser case 51 and is inserted into the groove of the reset sensor 462.

Referring to FIGS. 2 and 13 together, the drive control assembly 46 further includes a return sensor 463 arranged on the first control board 461. A surface of the housing 41 facing the first rail device 201 is provided with a third through hole 413, and the return sensor 463 is exposed outside the housing 41 through the third through hole 413. The first rail device 201 includes a return member 27 (as shown in FIG. 2) for corresponding to the return sensor 463. The laser and cutter device 40 moves in the second direction on the second rail device 203 to allow the return member 27 to be inserted into the third through hole 413 and cooperate with the return sensor 463 to output a return signal. When the return member 27 cooperates with the return sensor 463 to output the return signal, the laser and cutter device 40 no longer moves in the second direction. The external control center receives the return signal through the first control board 461 and records the current position information of the laser and cutter device 40 to determine an origin position of the laser and cutter device 40 in the second direction. In this case, the external control center can output the corresponding return control signal based on the requirement of the user through precise algorithms, so as to control the movement distance of the laser and cutter device 40 in the second direction on the second rail device 203. In this embodiment, the return sensor 463 is a groove-type optocoupler sensor. When the return member 27 moves in the second direction relative to the laser and cutter device 40 and is inserted into a groove of the return sensor 463, the return member 27 can cooperate with the return sensor 463 to output the return signal.

Referring to FIG. 5 and FIGS. 10 to 12 together, the laser and cutter device 40 further includes a second control board 47 electrically connected to the laser 52. The second control board 47 is connected to the housing 41, and is configured to transmit a second control signal to the laser 52 to control the power of the laser light emitted by the laser 52. In this way, the external control center can transmit the second control signal to the laser 52 through the second control board 47, so that the external control center can adjust the second control signal based on the requirement of the user, to adjust the power of the laser light emitted by the laser 52 for machining the workpiece. In this embodiment, a second fixing portion 414 extending in the third direction is provided in the housing 41. The first fixing portion 412 and the second fixing portion 414 are arranged oppositely. A surface of the first fixing portion 412 facing the second fixing portion 414 is provided with a first slide groove 4123, and a surface of the second fixing portion 414 facing the first fixing portion 412 is provided with a second slide groove 4141 corresponding to the first slide groove 4123. The second control board 47 is inserted into the first slide groove 4123 and the second slide groove 4141 along the third direction, so that the second control board 47 is connected to the housing 41.

The laser 52 is provided with an emission outlet 521 in the third direction, and the laser light of the laser 52 is emitted from the emission outlet 521. In this way, when the laser light of the laser 52 is emitted from the emission outlet 521, the laser light can perform processing operations such as cutting and engraving on the workpiece along the third direction.

The machining mechanism 50 further includes a radiator. The radiator includes multiple heat-conducting fins 522 arranged on an outer peripheral surface of the laser 52, and each of the multiple heat-conducting fins 522 extends in the third direction. The laser and cutter device 40 further includes a fan 48 connected to the housing 41. The fan 48 corresponds to the radiator, that is, the fan 48 blows air in the third direction. The heat dissipation area of the laser 52 is increased through the heat-conducting fins 522. When the fan 48 corresponding to the radiator blows air to the heat-conducting fins 522, the of heat from the laser 52 is dissipated more rapidly, ensuring that the temperature of the laser 52 is in a normal state when the workpiece is being machined, which avoids the rapid attenuation of the power of the laser light caused by the influence of the high temperature on the laser light emitted by the laser 52, and thereby avoiding influence on the workpiece machining of the laser and cutter device 40 by using the laser light as the processing medium through the laser 52.

In the embodiment, as shown in FIG. 23, two adjacent side surfaces of the laser 52 are each provided with multiple heat-conducting fins 522. For the convenience of description, the two adjacent side surfaces of the laser 52 with the heat-conducting fins 522 are referred to as a first surface and a second surface, respectively. The laser 52 is provided with a groove 523 on the first surface, a protrusion 524 is provided on a side surface of the laser 52 that is opposite to the first surface, and the laser case 51 is provided with a clamp groove 5131, corresponding to the protrusion 524, on an inner wall of the laser accommodation cavity 513. The user can use a screw to pass through the peripheral wall of the laser case 51 to press against a bottom wall of the groove 523, that is, the screw can pass through the peripheral wall of the laser case 51 to press against the first surface. The screw provides a pressing force for the laser 52 to allow the protrusion 524 of the laser 52 to be stably and reliably inserted into the clamp groove 5131. In this way, the laser 52 is accommodated in the laser accommodation cavity 513, that is, the laser 52 is fixedly connected to the laser case 51. In addition, the user can control the screw to no longer press against the first surface by rotating the screw, to release the connection between the laser 52 and the laser case 51, the operation is simple, and disassembly and assembly are convenient.

In the embodiment, the fan 48 is accommodated in an inner cavity of the housing 41. Specifically, the fan 48 is arranged on a surface of the first control board 461 facing away from the laser case 51, the first control board 461 is provided with a vent hole 4611, and an axis of the fan 48 is collinear with an axis of the vent hole 4611. In this way, the air blown by the fan 48 can be conveyed to the laser 52 through the vent hole 4611, to dissipate heat from the laser 52.

In an embodiment, the radiator further includes multiple radiation fins 514 arranged on the outer peripheral surface of the laser case 51, each of the radiation fins 514 extends in the third direction. The presence of the radiation fins 514 increases the heat dissipation area of the laser case 51 and further accelerates the heat dissipation of the laser 52. In this embodiment, as shown in FIG. 15, the laser case 51 is provided with multiple radiation fins 514 on one side surface thereof. For convenience of description, the surface of the laser case 51 with the radiation fins 514 is referred to as a third surface.

Referring to FIGS. 20, 21, and 23 together, the driver 24 is fixed to the third connecting portion 2115 of the rail frame 211, and a driving shaft of the driver 24 is connected to the transmission assembly 25 for driving the transmission assembly 25 to move. In this embodiment, as shown in FIG. 2, the two first rail devices 201 share the same driver 24, and the driver 24 is fixed to the rail frame 211 of one of the two first rail devices 201 to drive the mounting assemblies 23 of the two first rail devices 201 to move. It can be understood that each of the two first rail devices 201 may be provided with one driver 24.

Referring to FIGS. 20 to 23, the transmission assembly 25 includes a driving wheel 251, a driven wheel 253, and a synchronous belt 255. The driving wheel 251 is connected to the driving shaft of the driver 24. The driven wheel 253 is rotatably arranged on the rail frame 211, and the synchronous belt 255 is sleeved on the driving wheel 251 and the driven wheel 253. The synchronous belt 255 fixedly passes through the connecting groove 2315 of the connecting member 2312. In this embodiment, the driver 24 is a rotating motor which drives the driving wheel 251 to rotate, and the driving wheel 251 drives the synchronous belt 255. When the driver 24 drives the driving wheel 351 to rotate, the driving wheel 251 drives the synchronous belt 255 to move to further drive the connecting member 2312 to move, and thus the mounting assembly 23 is driven to move linearly along the first plain shaft 2131 and the second plain shaft 2133.

The transmission assembly 25 further includes a fixing bracket 257 (as shown in FIG. 21). The fixing bracket 257 is fixed to the rail frame 211, and supports the driven wheel 253. It can be understood that connecting member 2312 may be omitted, and the mounting plate 2311 is directly connected to the synchronous belt 255. It can be understood that the transmission assembly 25 may be omitted, and the driver 24 is directly connected to the mounting seat 231, the driver 24 may be a linear motor, and the driver 24 drives the mounting seat 231 to move linearly in the first direction.

Referring to FIGS. 1, 2, 17, and 21 together, when the laser and cutter machining apparatus 100 is required to machine the workpiece, the driver 24 drives the driving wheel 251 to rotate, and the driving wheel 251 drives the second rail device 203 to move linearly in the first direction on the first rail device 201. The driver 34 of the second rail device 203 drives the driving wheel 351 to rotate to drive the laser and cutter device 40 to move linearly in the second direction on the second rail device 203. In this way, the machining position of the laser and cutter device 40 can be changed through the movement of the second rail device 203 on the first rail device 201 and the movement of the laser and cutter device 40 on the second rail device 203.

It can be understood that the structure of the first rail device 201 may be similar to that of the second rail device 203, that is, it can be understood that the structure of the first rail device 201 according to the present application can be applicable to a rail guide mechanism of the linear motion of the laser and cutter machining apparatus 100, for example, it is applicable as the linear motion rail in any directions such as X-axis, Y-axis, Z1, and Z2 in FIG. 1.

Referring to FIGS. 16 and 21 together, in this embodiment, the laser and cutter device 40 moves in the second direction on the second rail device 203, and the pulley 333 of the second rail device 203 is directly rotatably mounted on the housing 41 of the laser and cutter device 40. In another embodiment, the laser and cutter device 40 may move in the first direction on the first rail device 201, and the housing 41 of the laser and cutter device 40 is fixed to the mounting plate 2311 of the first rail device 201. As the pulley 233 of the first rail device 201 is rotatably connected to the mounting plate 2311, the pulley 233 can be indirectly rotatably connected to the housing 41 of the laser and cutter device 40 through the mounting plate 2311.

Optionally, the laser and cutter machining apparatus 100 may further include a frame. A closed machining space is provided in the frame for storing and machining of the workpiece to be machined. The frame is provided with an opening in communication with the machining space, the frame is connected to a cover plate, and the cover plate is configured to rotatably cover the opening. The opening is configured to allow the user to place in the workpiece to be machined or take out the machined workpiece. The frame is formed by a bottom plate, side plates, and other parts being arranged in an enclosing manner to form the frame. The support device 10, the rail device 20, and the laser and cutter device 40 are arranged in the machining space. The laser and cutter device 40 is movable in the machining space through connection with the rail device 20, so as to perform laser engraving, laser cutting, cutter cutting, cutter scratching, and the like on the workpiece to be machined through laser or a cutter, to realize desktop level arrangement and miniaturization of the laser and cutter machining apparatus 100.
