DETAILED DESCRIPTION

The following illustrative embodiments are provided to illustrate the present disclosure, these and other advantages and effects can be apparent to those in the art after reading this specification.

It should be noted that all the drawings are not intended to limit the present disclosure. Various modifications and variations can be made without departing from the spirit of the present disclosure. Further, terms such as “up,” “down,” “front,” “rear,” “left,” “right,” “a,” etc. are for illustrative purposes and should not be construed to limit the scope of the present disclosure.

FIGS. 1A-1 and 1A-2 are schematic perspective views of a machining apparatus 1 according to the present disclosure. Referring to FIGS. 1A-1 and 1A-2, the machining apparatus 1 includes a transport device la, a height milling device 2, an edge milling device 3, a flipping device 4 and a hole forming device 5.

In an embodiment, for the machining apparatus 1 and for purpose of illustration, the direction of the production line is defined as a left or right direction (e.g., an arrow direction Y), a direction perpendicular to the production line is defined as a front or rear direction (e.g., an arrow direction X), and the height direction along the machining apparatus 1 is defined as a top or bottom direction (e.g., an arrow direction Z). It should be understood that the aforementioned orientations are used to illustrate the arrangement of the embodiment, and the present disclosure is not limited thereto.

The transport device la is used to transport (e.g., grip) a target object 9 to a required machining position of the production line. To facilitate placing of the target object 9 on the height milling device 2, the edge milling device 3, the flipping device 4 and/or the hole forming device 5, the transport device la is disposed over the height milling device 2, the edge milling device 3, the flipping device 4 and the hole forming device 5.

In an embodiment, referring to FIG. 1B, the transport device la includes at least a picking and placing component 10 for picking and placing the target object 9, and a support component 11. The picking and placing component 10 is displaceably disposed on the support component 11 and cooperates with the support component 11 so as to move the target object 9, thereby picking an placing the target object 9. For example, the support component 11 is a frame structure, which has two sets of door-shaped rod frames 110 (e.g., opposite to each other) vertically disposed on a base surface (e.g., floor) and a beam 111 disposed across the rod frames 110. The beam 111 is positioned over the height milling device 2, the edge milling device 3 and the flipping device 4 to serve as a displacement path of the picking and placing component 10. It should be understood that the support component 11 can be of various types and not limited to the above.

Further, the picking and placing component 10 includes a gripping portion l0a with a holding member 100 and a carrying portion 10b for arranging the gripping portion 10a. For example, the width D of the holding member 100 of the gripping portion l0a can be adjusted according to the requirement so as to grip the target object 9 having a different width. A hydraulic or pneumatic cylinder (serving as a power source 10d) can be used to control the distance of the two gripping portions l0a so as to grip or loosen the target object 9. The carrying portion 10b is a movable frame, which is vertically disposed on the beam 111 (or a position limiting member 112) and pivotally connected to a gear (not shown). The gear (not shown) is engaged with a rack 112a (as shown in FIG. 1C). A driving force causes the gear to move linearly on the rack 112a such that the picking and placing component 10 can move linearly back and forth in the arrow direction Y with a sliding base (e.g., the carrying portion 10b) and the sliding rail component (e.g., the position limiting member 112 and the rack 112a and gear on the position limiting member 112). For instance, the plurality of power sources 10d (e.g., the pneumatic or hydraulic cylinder of FIG. 1B) drives the gripping portion 10a to bring the holding member 100 to extend outward or retract inward (in the arrow direction Y), thus producing a loosening or holding action. Further, a retractable structure 101 connected to the gripping portion 10a is disposed on the bottom of the carrying portion 10b so as to lift or descend the gripping portion 10a. A motor (not shown) can be disposed over the carrying portion 10b so as to drive the carrying portion 10b to displace, thereby driving the gear to move linearly on the rack 112a.

Furthermore, the number of the picking and placing component 10 can be set according to needs. For example, the picking and placing component 10 are respectively arranged corresponding to machining positions of the height milling device 2, the edge milling device 3 and the flipping device 4 (as such, at least two sets of picking and placing components 10 are arranged). For instance, one picking and placing component 10 is arranged between the height milling device 2 and the edge milling device 3, and the other picking and placing component 10 is arranged between the edge milling device 3 and the flipping device 4. If needed, a plurality of picking and placing components 10 can be added between the rod frames 110 and the height milling device 2 to serve as intermediate transferring components of the target object 9. As such, the target object 9 can be continuously picked and placed at each machining position so as to complete machining processes of the entire production line.

In addition, referring to FIGS. 1D-1, 1D-2 and 1D-3, the target object 9 is an elevated floor, which has a first surface 9a (e.g., a floor surface), a second surface 9b (e.g., a bottom end) opposite to the first surface 9a, and a side surface 9c adjacent to and connecting the first surface 9a and the second surface 9b. For example, the target object 9 is a substantially rectangular body (e.g., a square plate), the bottom of the target object 9 (i.e., the second surface 9b, which is the bottom of the elevated floor) has a honeycomb shape, and four corners of the second surface 9b of the target object 9 have four foot bases 90. Referring to FIG. 1E, holes 900 can be formed in the four foot bases 90 so as to fasten the four foot bases 90 on support legs by using screws (the support legs are used by the elevated floor). For instance, end surfaces 9d of the foot bases 90 slightly protrude from the second surface 9b of the target object 9 (with a height difference h, as shown in FIG. 1D-3), and a flange 91 is formed at an edge of the first surface 9a and protrudes from the side surface 9c. The flange 91 is the four edges of the elevated floor to be processed by the edge milling device 3. Since the target object 9 of the embodiment is an elevated floor, it is referred to as elevated floor hereinafter.

FIGS. 2A-1 to 2C are schematic views of the edge milling device 3 according to the present disclosure. In an embodiment, an edge milling component 3a of the edge milling device 3 actuates in cooperation with the transport device la to process the flange 91 on the side surface 9c of the target object 8, 9 (elevated floor) of FIGS. 1D-1 to 1E. The flange 91 is the four edges of the elevated floor to be quickly processed by the edge milling device 3. For example, the edge milling device 3 is used to remove the burrs on the four sides around the elevated floor so as to process the four edge dimensions of the elevated floor. For instance, by using a man-machine control interface, machining values are inputted via a programmable logic controller (PLC) so as to control the four edge dimensions of the elevated floor to be processed.

Referring to FIGS. 2A-1 to 2C, the edge milling component 3a for processing the flange 91 of the target object 9 (e.g., four edges of the target object 9) includes at least a servo motor 36 (e.g., the servo motor 36 may be used as a motor), a milling tool 30, a support structure 33, and a carrying structure 34 displaceably disposed on the support structure 33 for carrying the milling tool 30. The milling tool 30 has a body 30a and a milling cutter 300 disposed on the top of the body 30a. The target object 9 is fastened on a fastening component 3b, the fastening component 3b includes a base platform 31 and a positioning structure 32 disposed on the base platform 31. At least an edge milling component 3a is disposed on the base platform 31 and positioned around the positioning structure 32. The target object 9 is placed on the positioning structure 32 by the transport device la, and the edge milling component 3a is displaced relative to the positioning structure 32 so as to perform an edge milling machining on the target object 9.

The base platform 31 is a machine tool working platform, which is substantially a rectangular body and has a working surface S of a rectangular planar shape.

In an embodiment, electromechanical components such as motors, wires or other related machine units that are required by the production line can be provided in the base platform 31, and the present disclosure is not limited as such.

The positioning structure 32 is arranged in the middle of the working surface S of the base platform 31, as shown in FIG. 2A-2, so as to position and carry the target object 9 as shown in FIG. 1D-1.

In an embodiment, the positioning structure 32 is a multi-layer rectangular plate body having a square-shaped placing platform 32a disposed thereon. The elevated floor is placed on the placing platform 32a, and one of a plurality of edge milling components 3a (four edge milling components 3a are shown in the embodiment) is placed at each of four sides of the placing platform 32a.

Further, the fastening component 3b further includes at least a fastening portion 320, 320a disposed outside the placing platform 32a so as to restrict the displacement of the target object 9 and avoid deviation of the target object 9. For example, referring to FIG. 2A-3, a gantry-shaped support frame 39 is disposed on front and rear sides of the base platform 31, and the fastening portion 320 is disposed on a main frame 390 extending on the surface of the support frame 39. As such, after the target object 9 is placed on the placing platform 32a, the foot bases 90 of the target object 9 can be tightly held diagonally by a plurality of fastening portions 320, thus preventing the target object 9 from deviating during the edge milling machining.

Furthermore, the fastening portion 320a can be disposed over the placing platform 32a so as to restrict the displacement of the target object 9 and avoid deviation of the target object 9. For example, referring to FIG. 2A-3, an arm frame 391 is disposed on the support frame 39 and pivotally connected to a stand frame 392, and the fastening portion 320a is disposed on the stand frame 392. As such, after the target object 9 is placed on the placing platform 32a, by rotating the stand frame 392, the fastening portion 320a can be pressed tightly on the second surface 9b of the target object 9, thereby preventing the target object 9 from deviating during an edge milling machining.

The edge milling device 3 has at least an edge milling component 3a disposed outside each side edge (front, rear, left and right sides) of the positioning structure 32 (or the placing platform 32a).

In an embodiment, the edge milling component 3a includes the milling tool 30, the support structure 33 disposed on the base platform 31, and the carrying structure 34 disposed on the support structure 33 for carrying the milling tool 30. The milling tool 30 has the milling cutter 300 disposed on the top of the body 30a. The carrying structure 34 is displaceably disposed on the support structure 33 so as to displace the milling tool 30 to the required position. It should be understood that there are various types of the milling cutter 300, and the present disclosure is not limited as such.

Further, the support structure 33 is a plate base body, which is displaceably disposed on the working surface S of the base platform 31. For example, the working surface S of the base platform 31 has a position limiting structure 37 for limiting the displacement direction of the support structure 23 and a power unit 38 for driving the support structure 33 and the carrying structure 34 to displace. For instance, the position limiting structure 37 is a double rail structure fastened on the base platform 31, and a sliding base 330 for mounting on the position limiting structure 37 is fastened on the bottom of the support structure 33 so as to slide on the position limiting structure 37, thereby bringing (e.g., driving) the support structure 33 to displace linearly. Further, a ball nut (not shown) and a ball screw rod 380 (fastened on the working surface S of the base platform 31) engaged with the ball nut are fastened on the bottom of the support structure 33. The power unit 38 includes a first motor 38a. The ball screw rod 380 is driven by the first motor 38a to rotate, thereby driving the ball nut to move linearly. As such, the support structure 33 is linearly displaced a long distance along the edge of the positioning structure 32 relative to the base platform 31, and hence the milling tool 30 can be linearly displaced along the side surface 9c of the target object 9 so as to process the flange 91 of the target object 9.

Furthermore, the carrying structure 34 is a frame base body, which is displaceably disposed on the support structure 33 so as to cause the milling tool 30 to move close to or away from the positioning structure 32. The power unit 38 further has a second motor 38b for driving the carrying structure 34 to displace. Therein, based on one side edge of the positioning structure 32, the displacement direction of the support structure 33 (the movement direction f2, b2 as shown in FIG. 2B) and the displacement direction of the carrying structure 34 (the movement direction f1, b1 as shown in FIG. 2B) are perpendicular to one another. For instance, a rail 35 is disposed at the upper side of the support structure 33, and a sliding block 340 disposed below the carrying structure 34 is cooperating with the rail 35 so as to move on the rail 35, thus allowing the second motor 38b to drive the carrying structure 34 to move linearly a short distance along the rail 35 relative to the support structure 33. Therefore, the milling tool 30 can move linearly to the required planar position or machining position so as to be close to or away from the positioning structure 32. For instance, a ball nut (not shown) is fastened on the lower side of the carrying structure 34, and a ball screw rod (not shown) engaged with the ball nut is fastened onto the support structure 33 and rotated by the second motor 38b. Since the ball screw rod merely rotates in place without moving, the ball nut is actuated by the ball screw rod so as to displace linearly. Hence, the carrying structure 34 is driven by the ball nut to displace linearly along the rail 35, and the milling tool 30 is linearly displaced to the required machining position.

In addition, the servo motor 36 and the milling tool 30 are disposed on the carrying structure 34 via a stand frame 34a, and the servo motor 36 and the milling tool 30 are integrated linearly so as to reduce the volume of the carrying structure 34. The milling tool 30 is directly driven by the servo motor 36 to rotate so as to allow the milling cutter 300 at the target position (e.g., attach to the flange 91 of the side surface 9c of the target object 9) to remove the burrs of the flange 91 of the target object 9. Therefore, the present disclosure is characterized in that the servo motor 36 directly drives the milling tool 30 to rotate, which not only reduces the volume of the edge milling device 3, but also improves the machining precision and machining speed via digital control of rotation of the servo motor 36. The conventional motor driving of the prior art cannot achieve such an efficiency.

When the edge milling device 3 is used on the production line, after the height milling machining is completed, the transport device 1a transports a single target object 9 from the height milling device 2 to the placing platform 32a of the positioning structure 32 of the edge milling device 3, and the fastening portions 320, 320a abut against the target object 9 so as to fasten the target object 9. Therein, the first surface 9a of the target object 9 faces the placing platform 32a, and the second surface 9b of the target object 9 faces upward.

Thereafter, through the second motor 38b, the carrying structure 34 is displaced close to (in the movement direction f1 of FIG. 2B) the positioning structure 32 (or the placing platform 32a) so as to displace the edge milling component 3a to the required position. Then, through the first motor 38a, the support structure 33 slides linearly along the position limiting structure 37 (in the movement direction f2 of FIG. 2B) so as to move the milling tool 30. As such, the servo motor 36 drives the milling cutter 300 of the milling tool 30 to mill the buns of the flanges 91 of the four side surfaces 9c of the target object 9, and hence the edge milling component 3a performs the edge milling machining on the target object 9 corresponding to each edge of the positioning structure 32 (or the placing platform 32a).

Thereafter, through the second motor 38b, the carrying structure 34 is displaced away (in the movement direction b1 of FIG. 2B) from the positioning structure 32 (or the placing platform 32a) so as to displace the milling tool 30 to the required position. Then, the first motor 38a drives the support structure 33 to slide linearly along the position limiting structure 37 (in the movement direction b2 of FIG. 2B), thus moving the edge milling component 3a back to the original place.

In summary, in the edge milling device 3 according to the present disclosure, the servo motor 36 drives the milling tool 30 to cause the edge milling component 3a to process the burrs of the flange 91 on the side surface 9c of the elevated floor, thereby speeding up the production, improving the production efficiency and reducing the labor cost.

Further, through design of the loop-type displacement of the edge milling component 3a (in the movement directions f1, f2, b1, b2 of FIG. 2B), the present disclosure prevents the milling cutter 300 of the milling tool 30 from repeatedly milling the flange 91 on the same side surface 9c so as to avoid excessive milling of the flange 91 on the side surface 9c of the target object 9 that otherwise may damage the flange 91 or cause the milling cutter 300 to induce mechanical noise.

The above-described descriptions of the detailed embodiments are to illustrate the implementation according to the present disclosure, and it is not to limit the scope of the present disclosure. Accordingly, all modifications and variations completed by those with ordinary skill in the art should fall within the scope of present disclosure defined by the appended claims.
