BACKGROUND OF THIS INVENTION
1. Field of this Invention
This invention relates to a processing assembly and relates particularly to a workpiece processing assembly with multiple working operations.
2. Description of the Related Art
Since a conventional processing machine can only be equipped with one processing tool, a workpiece should be processed through different processing machines separately in order to complete multiple working operations of the turning process. Alternatively, the processing tool of the processing machine can be changed manually after each working operation is completed in order to complete multiple working operations of the turning process with one processing machine. However, it affects the smoothness of the turning process and complicates the turning process. Further, the precision of the finished workpiece may be poor.
A machine tool 1 is disclosed in a PCT Application Publication No. 2016/063837, as shown in FIG. 1, the machine tool 1 comprises a working platform 11, a first positioning device 12 disposed on the working platform 11, a second positioning device 13 situated relative to the first positioning device 12, a first turning device 14 situated beside the first positioning device 12, a second turning device 15 situated beside the second positioning device 13, and a controlling device 16 electrically connected to the first positioning device 12, the second positioning device 13, the first turning device 14 and the second turning device 15. The working platform 11 defines a three-dimensional baseline including a Y-axis direction, an X-axis direction perpendicular to the Y-axis direction, and a Z-axis direction pointing upward. The first positioning device 12 is fixed on the working platform 11 and adapted to clamp one end of a workpiece 2 to be processed. The second positioning device 13 is movably disposed on a first transverse slide rail 131 and a first longitudinal slide rail 132 for being adapted to slide in the X-axis direction and the Y-axis direction reciprocatingly. The second positioning device 13 is adapted to clamp another end of the workpiece 2. Alternatively, the first positioning device 12 and the second positioning device 13 can adapted to clamp different workpieces 2 to be processed. The first turning device 14 is movably disposed on a second transverse slide rail 141 and a second longitudinal slide rail 142 for being adapted to slide in the X-axis direction and the Y-axis direction reciprocatingly. The first turning device 14 has a first carrier 143 adapted to accommodate at least one processing tool (not shown). The second turning device 15 has a support base 151 fixed on the working platform 11, a second carrier 152 adapted to accommodate at least one processing tool (not shown), and a flat surface 153 formed on the second carrier 152. Referring to FIG. 1, and FIGS. 2A-2B, the controlling device 16 can actuate the second turning device 15 based on a control command to carry out a rotation of the second carrier 152 and situate the flat surface 153 relative to the second positioning device 13. Thus, the second positioning device 13 can slide on the first transverse slide rail 131 in the X-axis direction without being hindered by the second carrier 152. Hence, the second turning device 15 and the second positioning device 13 will not interfere each other during the turning process to thereby complete the turning process.
Although the machine tool 1 can complete multiple working operations of the turning process, the second turning device 15 is unable to process the workpiece 2 when the first positioning device 12 and the second positioning device 13 clamp the same workpiece 2. When the second positioning device 13 slides on the first transverse slide rail 131 toward the first positioning device 12 to adjust the distance between the first positioning device 12 and the second positioning device 13 in order to clamp the workpiece 2 stably, the second carrier 152 must be rotated to allow the flat surface 153 to face the second positioning device 13 to thereby prevent the second positioning device 13 from colliding with the second carrier 152. However, the flat surface 153 is unable to carry any processing tool, and that causes the second turning device 15 is unable to process the workpiece 2. Thus, all processing tools needed for processing the workpiece 2 must be installed on the first carrier 143 of the first turning device 14. If the first carrier 143 is unable to accommodate all processing tools, the processing tools of the first carrier 143 should be replaced manually in order to complete multiple working operations. Further, if the end of the workpiece 2 clamped by the second positioning device 13 should be processed, the workpiece 2 should be removed to situate the end of the workpiece 2 which is formerly clamped by the second positioning device 13 to be clamped by the first positioning device 12 in order that two ends of the workpiece 2 can be processed by the first turning device 14 respectively. Hence, the turning process becomes complicated and time-consuming. The processing efficiency is poor. The processing quality is difficult to be controlled, and that requires to be improved.

The controlling device 35 is adapted to actuate respective operations of the positioning assembly 32, the first turning device 33 and the second turning device 34 based on a control command transmitted to the controlling device 35.
The working platform 31 has a processing portion A and an operating portion B located relative to the processing portion A. The processing portion A defines at least a first processing area A1 and at least a second processing area A2 defined relative to the first processing area A1. The operating portion B defines at least a first operating area B1 defined beside the first processing area A1 and at least a second operating area B2 defined beside the second processing area A2. The working platform 31 has a first transverse slide rail 311 disposed in the second processing area A2, a second transverse slide rail 312 disposed in the first operating area B1, a first longitudinal slide rail 313 slidably disposed on the second transverse slide rail 312, and a second longitudinal slide rail 314 disposed in the second operating area B2. The first longitudinal slide rail 313 and the second longitudinal slide rail 314 are preferably perpendicular to the operating portion B. The working platform 31 defines a three-dimensional baseline including a Y-axis direction, an X-axis direction perpendicular to the Y-axis direction, and a Z-axis direction pointing upward.
The positioning assembly 32 is actuated by the controlling device 35 to clamp or release the workpiece 4. The positioning assembly 32 has a first positioning device 321 disposed in the first processing area A1 and a second positioning device 322 movably disposed on the first transverse slide rail 311 of the second processing area A2 for being adapted to slide in the X-axis direction reciprocatingly. The second positioning device 322 is located relative to the first positioning device 311. In this preferred embodiment, the first positioning device 321 is fixed in the first processing area A1. The first positioning device 321 and the second positioning device 322 can be adapted to clamp two ends of the same workpiece 4 respectively. Alternatively, the first positioning device 321 and the second positioning device 322 can be adapted to clamp different workpieces 4. Meanwhile, the controlling device 35 can drive the second positioning device 322 to slide on the first transverse slide rail 311 to further adjust the distance between the first positioning device 321 and the second positioning device 322.
The first turning device 33 is situated beside the first positioning device 321 and is movably disposed on the first longitudinal slide rail 313 of the first operating area B1 for being adapted to slide in the Y-axis direction reciprocatingly as shown in FIG. 4A and FIG. 4B. Referring to FIG. 5A and FIG. 5B, the first turning device 33 is capable of sliding in the X-axis direction reciprocatingly by sliding the first longitudinal slide rail 313 along the second transverse slid rail 312. The first turning device 33 has a first carrier 331 adapted to accommodate at least two first processing tools C1 serving to turn the workpiece 4. Further, the second turning device 34 is situated beside the second positioning device 322 and is movably disposed on the second longitudinal slide rail 314 of the second operating area B2 for being adapted to slide in the Y-axis direction reciprocatingly as shown in FIG. 6A and FIG. 6B. The second turning device 34 has a second carrier 341 adapted to accommodate at least two second processing tools C2. The controlling device 35 can carry out a rotation of the first carrier 331 and the second carrier 341 respectively so that the needed first processing tool C1 and needed second processing tool C2 are rotated to face the workpiece 4 automatically. Meanwhile, each first processing tool C1 and each second processing tool C2 is capable of rotating on its own axis to achieve different working operations. Moreover, the controlling device 35 can also drive the first turning device 33 to slide on the second transverse slide rail 312 and the first longitudinal slide rail 313 to adjust the distance between the first turning device 33 and the first positioning device 321 and drive the second turning device 34 to slide on the second longitudinal slide rail 314 to adjust the distance between the second turning device 34 and the second positioning device 322 to thereby move the first processing tool C1 and the second processing tool C2 to a proper processing position. Referring to FIG. 8A and FIG. 8B, in this preferred embodiment, the first turning device 33 is movably disposed on a first elevating unit 332 for being adapted to slide in the Z-axis direction reciprocatingly. Referring to FIG. 9A and FIG. 9B, the second turning device 34 is movably disposed on a second elevating unit 342 for being adapted to slide in the Z-axis direction reciprocatingly. Thus, the first turning device 33 and the second turning device 34 are capable of processing each side and each surface of the workpiece 4 based on different working operations.
Referring to FIG. 7, here takes an example that the turning process is aimed at processing the same workpiece 4. During the turning process of the workpiece 4, the first positioning device 321 is adapted to clamp one end of the workpiece 4. The second positioning device 322 then actuated by the controlling device 35 to slide on the first transverse slide rail 311 in the X-axis direction toward the first positioning device 321 to thereby clamp another end of the workpiece 4. Hence, the workpiece 4 is fixed stably between the first positioning device 321 and the second positioning device 322. After that, the controlling device 35 actuates the first turning device 33 and the second turning device 34 to carry out a rotation of the first carrier 331 and the second carrier 341 respectively to further situate the needed first processing tool C1 and the needed second processing tool C2 to face the workpiece 4. Next, the controlling device 35 actuates the first turning device 33 to slide on the second transverse slide rail 312 in the X-axis direction to further aim the first processing tool C1 at the workpiece 4. The first turning device 33 then slides on the first longitudinal slide rail 313 in the Y-axis direction to adjust the distance between the workpiece 4 and the first processing tool C1. Thus, the first processing tool C1 of the first turning device 33 is moved to a proper processing position for processing the workpiece 4. During the adjustment of the first turning device 33, the controlling device 35 simultaneously actuates the second turning device 34 to slide on the second longitudinal slide rail 314 in the Y-axis direction to further adjust the distance between the workpiece 4 and the second processing tool C2, and the second processing tool C2 is then moved to a proper processing position for processing the workpiece 4. Thus, the workpiece 4 can be processed simultaneously by the first turning device 33 and the second turning device 34.
Referring to FIG. 8 and FIG. 9, here takes an example that the turning process is aimed at processing different workpieces 4. During the turning process of two workpieces 4, the first positioning device 321 and the second positioning device 322 are adapted to clamp different workpieces 4 respectively. Next, the controlling device 35 actuates the first turning device 33 and the second turning device 34 to carry out a rotation of the first carrier 331 and the second carrier 341 respectively to further move the needed first processing tools C1 to face the corresponding workpiece 4 and move the needed second processing tool C2 to face the corresponding workpiece 4. After that, the controlling device 35 actuates the second positioning device 322 to slide on the first transverse slide rail 311 in the X-axis direction to situate the workpiece 4 relative to the second processing tool C2 of the second turning device 34. The controlling device 35 then actuates the second turning device 34 to slide on the second longitudinal slide rail 314 in the Y-axis direction to situate the second processing tool C2 in a proper processing position for processing the corresponding workpiece 4 clamped by the second positioning device 322. Simultaneously, the controlling device 35 actuates the first turning device 33 to slide on the second transverse slide rail 312 in the X-axis direction to further position the first processing tool C1 relative to the corresponding workpiece 4. The first turning device 33 then slides on the first longitudinal slide rail 313 in the Y-axis direction to move the first processing tool C1 to a proper processing position for processing the corresponding workpiece 4 clamped by the first positioning device 321. Hence, the first turning device 33 and the second turning device 34 can process different workpieces 4 respectively.
Referring to FIG. 3, FIGS. 10A-10B and FIGS. 11A-11B, the controlling device 35 can actuate the first turning device 33 to slide on the first elevating unit 332 in the Z-axis direction to adjust the height of the first processing tool C1 of the first turning device 33. Meanwhile, the second turning device 34 can slide on the second elevating unit 342 in the Z-axis direction to adjust the height of the second processing tool C2 of the second turning device 34. Therefore, the first processing tool C1 and the second processing tools C2 are precisely moved to aim at the workpiece 4 effectively. Thus, the workpiece processing assembly with multiple working operations 3, unlike the conventional machine tool 1, does not require the flat surface 153 (not shown) to prevent the second positioning device 322 from colliding with the second turning device 34. Hence, the second carrier 341 can be equipped with more second processing tools C2. Moreover, the workpiece processing assembly 3 can simultaneously process the same workpiece 4 or different workpieces 4 according to needs and execute the multiple working operations smoothly and speedily. Meanwhile, a rotation of the first carrier 331 and the second carrier 341 actuated by the controlling device 35 allows the first processing tools C1 and the second processing tools C2 to be changed automatically to thereby avoid the inconvenience caused by replacing the first processing tools C1 and the second processing tools C2 manually. Thus, the processing efficiency is increased and the processing quality is improved.
Referring to FIG. 12 shows a second preferred embodiment of the workpiece processing assembly with multiple working operations 3 of this invention. The correlated elements and the concatenation of elements, the operation and objectives of the second preferred embodiment are the same as those of the first preferred embodiment. This embodiment is characterized in that the first transverse slide rail 311 extends from the second processing area A2 to the first processing area A1. Both of the first positioning device 321 and the second positioning device 322 of the positioning assembly 32 are movably disposed on the first transverse slide rail 311 for being adapted to slide in the X-axis direction reciprocatingly. The first turning device 33 is movably disposed on the first longitudinal slide rail 313 of the first operating area B1 to slide in the Y-axis direction reciprocatingly. The second turning device 34 is movably disposed on the second longitudinal slide rail 314 of the second operating area B2 for being adapted to slide in the Y-axis direction reciprocatingly.
Referring to FIG. 12 and FIG. 13, here takes an example that the turning process is aimed at processing the same workpiece 4. During the turning process of the workpiece 4, the first positioning device 321 and the second positioning device 322 slide on the first transverse slide rail 311 in the X-axis direction to clamp two ends of the same workpiece 4 respectively and move the workpiece 4 relative to the first turning device 33 and the second turning device 34. Meanwhile, the first turning device 33 slides on the first longitudinal slide rail 313 in the Y-axis direction to move the first processing tool C1 to a proper position for processing the workpiece 4. The second turning device 34 slides on the second longitudinal slide rail 314 in the Y-axis direction to move the second processing tool C2 to a proper processing position for processing the workpiece 4. Therefore, multiple working operations of the turning process can be executed smoothly. The processing efficiency is increased and the processing quality is improved effectively.
Referring to FIG. 14, here takes an example that the turning process is aimed at processing different workpieces 4. During the turning process of different workpieces 4, the first positioning device 321 and the second positioning device 322 clamp different workpieces 4 respectively. The first positioning device 321 then slides on the first transverse slide rail 311 in the X-axis direction to situate the workpiece 4 relative to the first turning device 33. After that, the first turning device 33 slides on the first longitudinal slide rail 313 in the Y-axis direction to move the first processing tool C1 to a proper position for processing the workpiece 4 clamped by the first positioning device 321. Simultaneously, the second positioning device 322 also slides on the first transverse slide rail 311 in the X-axis direction to situate the workpiece 4 relative to the second turning device 34. The second turning device 34 then slides on the second longitudinal slide rail 314 in the Y-axis direction to move the second processing tool C2 to a proper position for processing the workpiece 4 clamped by the second positioning device 322. The first processing tool C1 of the first turning device 33 and the second processing tool C2 of the second turning device 34 can be changed automatically by the rotation of the first carrier 331 and the second carrier 341 actuated by the controlling device 35 to thereby complete the multiple working operations of the turning process.
To sum up, the workpiece processing assembly with multiple working operations of this invention takes advantages of the first transverse slide rail to adjust the distance between the first positioning device and the second positioning device to thereby clamp at least one workpiece stably, the second transverse slide rail and the first longitudinal slide rail to adjust the distance between the first positioning device and the first turning device to thereby move the first processing tool to a proper processing position, and the second longitudinal slide rail to adjust the distance between the second positioning device and the second turning device to thereby move the second processing tool to a proper processing position. Thus, multiple working operations can be executed smoothly and speedily. The inconvenience caused by replacing processing tools during the turning process is prevented, the processing efficiency is increased effectively, and the processing quality is improved.
While the embodiments of this invention are shown and described, it is understood that further variations and modifications may be made without departing from the scope of this invention.
