[0021] according to Figure 1-5 As shown, this embodiment proposes a fixed worktable for precision grinding of large planar workpieces, including a rotating mounting damping component 1 and a clamping mechanism 3.

[0022] The clamping mechanism 3 includes a mounting platform 301, a fourth motor 302, a four-way gear set 303, a threaded bar 304, a threaded compartment 305, a connecting frame 306, a sliding base 307, an assembly frame 308, and a clamping bar 309. The mounting platform 301 is located at the top of the displacement adjustment component 2. The mounting platform 301 is equipped with a four-way gear set 303 that connects to the output end of the fourth motor 302. The output end of the four-way gear set 303 is equipped with a threaded bar 304 that is threadedly connected to the threaded compartment 305. The outer end of the threaded bar 304 is equipped with a connecting frame 306. The sliding base 307 is located above the connecting frame 306. The top side of the sliding base 307 is equipped with an assembly frame 308. The inner end of the assembly frame 308 is equipped with a clamping bar 309.

[0023] The sliding base 307 and the assembly frame 308 are distributed at equal angles around the central axis of the mounting platform 301.

[0024] In this embodiment, during use, the fourth motor 302 on the mounting platform 301 outputs power to drive the four-one gear set 303 to mesh and drive, so that the threaded bar 304 and the threaded chamber 305 output power, so that the connecting frame 306 pushes the sliding base 307 to drive, and the clamping bar 309 on the assembly frame 308 clamps the product.

[0025] The rotating shock-absorbing assembly 1 includes a base platform 101, a first gearbox 102, a first motor 103, a rotating column 104, a rotating table 105, and a shock-absorbing frame 106. The first gearbox 102, on which the first motor 103 is mounted, is located above the middle of the base platform 101. The rotating column 104 is located at the output end of the first gearbox 102. The rotating table 105 is located above the rotating column 104. The shock-absorbing frame 106 is located above both ends of the rotating table 105.

[0026] In this embodiment, when processing is required, the first motor 103 outputs power to drive the output end to run, so that after the first gearbox 102 outputs power, the rotating column 104 drives the rotating table 105 to rotate to a suitable angle position.

[0027] The displacement adjustment component 2 includes a double-opening box 201, a second motor 202, a lead screw assembly 203, a sliding block 204, a hydraulic telescopic arm 205, a hinge base 206, a hinge frame 207, a swing table 208, a second gearbox 209, a third motor 2010, a meshing gear set 2011, and a rotating support 2012. The double-opening box 201 is located on the top side of the shock absorber frame 106. The lead screw assembly 203 connected to the output end of the second motor 202 is provided on the double-opening box 201, and the lead screw assembly 203 is threadedly connected to the sliding block 204.

[0028] In this embodiment, when it is necessary to adjust the relative position, the second motor 202 on the double-opening box 201 is used to output power to drive the output end to run, so that after the lead screw assembly 203 runs, it drives the sliding block 204 to adjust to a suitable angle position.

[0029] A hydraulic telescopic arm 205 is provided on the inner side of the sliding block 204, and a hinge base 206 is provided at the inner end of the hydraulic telescopic arm 205. The hinge base 206 is hinged to the swing table 208 through the hinge frame 207.

[0030] In this embodiment, when the sliding block 204 is adjusted, the hinge base 206 and the hinge frame 207 adjust the swing angle of the swing table 208, and the hydraulic telescopic arm 205 outputs and runs so that the swing table 208 is adjusted to a suitable position.

[0031] A second gearbox 209 is provided in the lower middle part of the swing table 208, and a meshing gear set 2011 connected to the output end of the third motor 2010 is provided inside the second gearbox 209. A rotating support 2012 is provided at the output end of the meshing gear set 2011.

[0032] In this embodiment, the third motor 2010 outputs power to drive the output end to run, so that after the meshing gear set 2011 outputs and runs, the rotating support 2012 above the second gearbox 209 drives the clamping mechanism 3 to run and adjust to a suitable angle position.

[0033] The working principle of this large flat workpiece precision grinding fixed worktable is as follows: During use, the fourth motor 302 on the mounting platform 301 outputs power, causing the four-to-one gear set 303 to mesh and drive. This drives the threaded bar 304 and threaded chamber 305, which in turn cause the connecting frame 306 to push the sliding base 307, thus clamping the product on the assembly frame 308 with the clamping bar 309. When processing is required, the first motor 103 outputs power to drive the output end, causing the first gearbox 102 to output power, which in turn causes the rotating column 104 to drive the rotary table 105 to rotate to a suitable angle position. When relative positioning needs adjustment... When the second motor 202 on the double-opening box 201 is used to output power to drive the output end to run, so that after the lead screw assembly 203 runs, it drives the sliding block 204 to adjust to a suitable angle position. When the sliding block 204 is adjusted, the hinge base 206 and the hinge frame 207 adjust the swing angle of the swing table 208, and after the hydraulic telescopic arm 205 runs, the swing table 208 is adjusted to a suitable position. The third motor 2010 outputs power to drive the output end to run, so that after the meshing gear assembly 2011 runs, the rotating support 2012 above the second gearbox 209 drives the clamping mechanism 3 to run and adjust to a suitable angle position.
