In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0040] This application provides a worktable and laser processing equipment to solve the technical problem of low processing accuracy in laser processing equipment.

[0041] In the embodiments of this application, such as Figures 1 to 3 As shown, the worktable includes a fixed component 1 and a rotating component 2. The fixed component 1 is provided with mounting holes 111 and multiple first fixing positions 121, both of which are located on the top surface of the fixed component 1. The rotating component 2 is provided with multiple second fixing positions 221, which are located on the top surface of the rotating component 2, and the rotating component 2 is rotatably disposed within the mounting holes 111.

[0042] In this embodiment, the worktable can be used to fix the workpiece. Alternatively, the worktable can be used to fix a fixture, and the workpiece can be fixed to the fixture. In subsequent embodiments, the worktable fixing a fixture will be used as an example for explanation.

[0043] Since there are multiple first fixing positions 121, after the fixture is placed on the fixing component 1, it can be fixed to the corresponding first fixing position 121 according to its shape, thus facilitating the fixing of irregularly shaped workpieces. Alternatively, the fixture can be placed on the rotating component 2 and then fixed to the corresponding second fixing position 221, thus facilitating the fixing of cylindrical workpieces.

[0044] After the fixture is fixed on the rotating assembly 2, the rotating assembly 2 rotates, which can drive the fixture to rotate, thereby driving the cylindrical workpiece to rotate, thus facilitating the processing of the cylindrical workpiece by the laser beam.

[0045] The fixing component 1 of this application embodiment is provided with a plurality of first fixing positions 121 so as to fix the fixture to the corresponding first fixing position 121, and then fix the irregular workpiece to the fixture to achieve the fixing of the irregular workpiece; the rotating component 2 is provided with a plurality of second fixing positions 221 so as to fix the fixture to the second fixing position 221, and then fix the cylindrical workpiece to the fixture to achieve the fixing of the cylindrical workpiece; the fixing component 1 is also provided with a mounting hole 111, and the rotating component 2 is rotatably disposed in the mounting hole 111 so that the rotating component 2 and the fixing component 1 are combined into one unit, thereby being compatible with fixing irregular workpieces and cylindrical workpieces; furthermore, according to the shape of the workpiece to be processed, the fixture can be fixed to the corresponding fixing component 1 or rotating component 2, thereby improving the stability and accuracy of the fixing fixture, so as to improve the processing accuracy of the workpiece.

[0046] In one embodiment, such as Figure 1 As shown, the top surface of the rotating component 2 is circular, and the top surface of the rotating component 2 is flush with the top surface of the fixed component 1.

[0047] The top surface of the rotating component 2 is flush with the top surface of the fixed component 1, which facilitates the fixing of the fixture. This avoids the top surface of the rotating component 2 interfering with the fixing of the fixture on the fixed component 1, or the top surface of the fixed component 1 interfering with the fixing of the fixture on the rotating component 2.

[0048] In one embodiment, such as Figure 3 and Figure 4 As shown, the second fixing positions 221 are spaced apart around the center of the top surface of the rotating assembly 2, so that the second fixing positions 221 are distributed in a ring, so as to facilitate fixing the fixture to the rotating assembly 2 through the corresponding second fixing positions 221. Then, the cylindrical workpiece is fixed to the fixture, thereby improving the stability and accuracy of fixing the fixture, and thus improving the stability and accuracy of fixing the workpiece.

[0049] In this embodiment, the second fixed position 221 can also be distributed in a spiral shape.

[0050] In one embodiment, such as Figure 3 and Figure 4 As shown, the radius of the center position of some of the second fixing positions 221 around the top surface of the rotating assembly 2 is larger than the radius of the center position of the other part of the second fixing positions 221 around the top surface of the rotating assembly 2. This makes the second fixing positions 221 arranged in a ring with different diameters, so as to facilitate fixing the fixture to the rotating assembly 2 through the corresponding second fixing positions 221.

[0051] In one embodiment, such as Figure 3 and Figure 4 As shown, the rotating assembly 2 is also provided with multiple third fixing positions 222, which extend radially along the top surface of the rotating assembly 2. This allows the fixture to be fixed at any radial position on the top surface of the rotating assembly 2, thereby improving the stability and accuracy of the fixture. The fixture can also be fixed simultaneously by the second fixing position 221 and the third fixing position 222 to further improve the stability of the fixture.

[0052] In one embodiment, such as Figure 1 and Figure 5 As shown, both the first fixing position 121 and the second fixing position 221 are threaded holes. The third fixing position 222 includes a first slot 2221 and a second slot 2222, with the first slot 2221 communicating with the second slot 2222 and located below the second slot 2222. The width of the first slot 2221 is greater than the width of the second slot 2222, and both the first slot 2221 and the second slot 2222 extend radially along the top surface of the rotating assembly 2.

[0053] Screws can be inserted into both the first fixing position 121 and the second fixing position 221 to fix the fixture to the fixing component 1 or the rotating component 2. A bolt can be placed in the third fixing position 222, with the bolt head located in the first slot 2221 and the bolt shank extending from the top surface of the rotating component 2 from the second slot 2222. After the bolt shank passes through the fixture, the fixture can be fixed to the rotating component 2 by screwing a nut onto the bolt shank.

[0054] In one embodiment, such as Figure 1 and Figure 2 As shown, the top surface of the fixed component 1 is also provided with a first positioning hole 122, and the top surface of the rotating component 2 is also provided with a second positioning hole 223. Positioning pins can be inserted into both the first positioning hole 122 and the second positioning hole 223 to facilitate the positioning of the fixture.

[0055] In one embodiment, such as Figure 3 and Figure 4As shown, a second positioning hole 223 is provided at the center of the top surface of the rotating component 2. A positioning pin can be inserted into the second positioning hole 223 to facilitate the positioning of the fixture. Since the second positioning hole 223 is located at the center of the top surface of the rotating component 2, the fixture can be fixed at the center of the top surface of the rotating component 2, thereby improving the positioning accuracy of the fixture.

[0056] In one embodiment, such as Figure 3 and Figure 4 As shown, there are multiple second positioning holes 223, one of which is located at the center of the top surface of the rotating component 2, and the remaining second positioning holes 223 are arranged around the center of the top surface of the rotating component 2.

[0057] In one embodiment, such as Figure 1 and Figure 3 As shown, the worktable also includes a first positioning element and a second positioning element 3. The first positioning element is disposed within the first positioning hole 122, and the second positioning element 3 is disposed within the second positioning hole 223. Both the first positioning element and the second positioning element 3 can be used to position the fixture to improve the positional accuracy of the fixture.

[0058] In this embodiment, the first positioning member or the second positioning member 3 can be inserted into the corresponding positioning pin hole on the fixture to achieve positioning of the fixture.

[0059] In one embodiment, both the first positioning element and the second positioning element 3 can be pins.

[0060] In one embodiment, such as Figure 1 and Figure 2 As shown, the fixing component 1 includes a support platform 11 and a plurality of support plates 12, and mounting holes 111 are provided on the top surface of the support platform 11. The support plates 12 are spaced apart on the top surface of the support platform 11, and the first fixing position 121 is provided on the support plate 12. The top surface of the rotating component 2 is flush with the top surface of the support plate 12.

[0061] By setting the first fixing position 121 on the support plate 12 and then setting the support plate 12 on the support table 11, the machining area of ​​the first fixing position 121 can be reduced, thereby reducing machining costs and improving machining accuracy. That is, machining the first fixing position 121 on the support plate 12, since the support plate 12 has a relatively small area, can improve the accuracy of machining the first fixing position 121 on the support plate 12.

[0062] In one embodiment, such as Figure 1 and Figure 2 As shown, the first positioning hole 122 is provided on the support plate 12 to reduce the cost of machining the first positioning hole 122 and improve the accuracy of machining the first positioning hole 122.

[0063] In one embodiment, such as Figure 1 and Figure 3 As shown, the rotating assembly 2 includes a drive unit 21 and a turntable 22. The drive unit 21 is rotatably located at the output end of the drive unit 21, and the drive unit 21 is used to drive the turntable 22 to rotate. The second fixed position 221 is located on the turntable 22, and the top surface of the turntable 22 is flush with the top surface of the fixed assembly 1.

[0064] After fixing the fixture to the turntable 22 and then fixing the cylindrical workpiece to the fixture, the drive unit 21 drives the turntable 22 to rotate, so that the turntable 22 drives the fixture to rotate, and the fixture drives the cylindrical workpiece to rotate, thereby facilitating the processing of the cylindrical workpiece using a laser beam.

[0065] In one embodiment, such as Figure 1 and Figure 3 As shown, the third fixing position 222 and the second positioning hole 223 are both located on the turntable 22.

[0066] In one embodiment, such as Figure 1 and Figure 3 As shown, the rotating assembly 2 also includes a pad 23, and the driving unit 21 is disposed on the pad 23 so that the driving unit 21 is raised by the pad 23, so that the top surface of the turntable 22 can be flush with the top surface of the fixed assembly 1.

[0067] Furthermore, this application also provides a laser processing device, which includes a worktable. The specific structure of the worktable is as described in the above embodiments. Since the laser processing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments.

[0068] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
