The movable roller 103 facilitates the movement of the mechanical component when the fixing component 2 pushes the mechanical component for clamping and fixing. The support plate 104 plays a role in supporting and installing the first driving component 3.

[0030] In one embodiment, the fixing component 2 includes a double-headed threaded rod 201. The double-headed threaded rod 201 movably penetrates through the interior of the workbench 1.

[0038] In one embodiment, the grinding assembly 5 includes an electric telescopic rod 501. One end of the electric telescopic rod 501 is fixedly installed at the bottom of the mounting seat 403. The output end of the electric telescopic rod 501 is fixedly installed with a connecting plate 502. A grinding motor 503 is fixedly installed at the bottom of the connecting plate 502. The output end of the grinding motor 503 is connected with a limiting sleeve 504. A transmission rod 505 is movably embedded inside the limiting sleeve 504. One end of the transmission rod 505 is fixedly installed with a limiting plate 506. The limiting plate 506 moves inside the limiting sleeve 504.

[0039] Specifically: a limiting groove body that engages with the limiting plate 506 is provided at the upper end of the inner wall of the limiting sleeve 504. The limiting plate 506 moves inside the limiting groove body to play a limiting role on the transmission rod 505 through the limiting sleeve 504, so that when the grinding motor 503 drives the limiting sleeve 504 to rotate, the transmission rod 505 and the grinding disc 507 are driven to rotate synchronously through the limiting plate 506.

[0040] Working principle: When using this device to grind large plate-shaped mechanical workpieces, first place the mechanical workpiece on top of the movable roller 103 on the surface of the workbench 1, align one side of the mechanical workpiece with the calibration line on the surface of the workbench 1, and drive the double-headed threaded rod 201 to rotate by rotating the rotating handle 202. The two ends of the double-headed threaded rod 201 drive the two mounting plates 203 to move synchronously inward to squeeze both sides of the mechanical component for fixation. After inputting the perimeter information of the mechanical workpiece through the external control terminal, the device is started. The electric telescopic rod 501 will start to drive the grinding motor 503 to move downward so that the grinding disc 507 fits on the surface of the mechanical component. The grinding motor 503 starts to drive the grinding disc 507 to rotate for grinding. When the grinding disc 507 contacts the surface of the mechanical component, it will push the transmission rod 505 and the limit plate 506 to squeeze the spring 508 for buffering, avoiding damage to the grinding motor 503 and the mechanical component caused by hard contact between the grinding disc 507 and the surface of the mechanical component. The forward and reverse motor 302 will start to drive the threaded rod 303 to rotate to drive the mounting slide 305, thereby driving the driving component 4 to move the grinding component 5 back and forth on the surface of the mechanical component for grinding. The forward and reverse motor 401 will start to drive the threaded rod 402 and the mounting seat 403 to drive the grinding component 5 to move left and right on the surface of the mechanical component for grinding. By pre-inputting the perimeter data of the mechanical component, the driving component 1 and the driving component 4 drive the grinding component 5 to perform comprehensive grinding treatment on the surface of the mechanical component, replacing manual labor and improving the grinding efficiency.
