[0024] The grinding mechanism 5 includes a slider 501, a screw 502 is internally threaded onto the slider 501, a drive motor 503 is fixedly connected to one side of the screw 502, a mounting bracket 504 is provided on the outside of the drive motor 503, the mounting bracket 504 is slidably mounted on the support frame 4, a hydraulic cylinder 505 is fixedly mounted above the mounting bracket 504, a fixing plate 506 is fixedly mounted above the hydraulic cylinder 505, the fixing plate 506 is fixedly mounted on the support frame 4, an mounting rod 507 is fixedly mounted at the front end of the slider 501, and a grinding disc is fixedly mounted at the front end of the mounting rod 507 by bolts.

[0025] A groove 6 matching the screw 502 is provided at the connection between the support frame 4 and the screw 502. The groove 6 is located on the inner side of the support frame 4. Example 2

[0026] In addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0027] A transparent protective cover 7 is hinged to one side of the frame 1. The transparent protective cover 7 can reduce the spread of workpiece debris.

[0028] A spraying structure 8 is fixedly installed on one side of the support frame 2. The spraying structure 8 includes a water storage tank 801. A water pump 802 is fixedly installed inside the water storage tank 801. A connecting hose 803 is fixedly connected to the output end of the water pump 802. One end of the connecting hose 803 passes through the support frame 2 and is fixedly connected to a diversion pipe 804. An installation box 805 is fixedly installed on the outside of the diversion pipe 804. The installation box 805 is fixedly installed above the two support frames 2. The lower part of the diversion pipe 804... A nozzle 806 is fixedly installed in the spray structure 8, with the end of the nozzle 806 penetrating through the mounting box 805. The water pump 802 of the spray structure 8 can pump water from the water storage tank 801 to the connecting hose 803, and then through the connecting hose 803 to the diversion pipe 804. The diversion pipe 804 then diverts the water to the nozzle 806, so that the water can be sprayed onto the workpiece through the nozzle 806. This water can reduce the spread of workpiece debris and reduce the temperature of the workpiece, thus achieving a cooling effect.

[0029] The frame 1 has a collection chamber 9 located at the mounting box 805. A drawer 10 is slidably installed inside the collection chamber 9. A screen plate is fixedly installed inside the drawer 10. The collection chamber 9 can collect the water sprayed by the spraying structure 8 and the debris generated by the grinding of the workpiece. The screen plate inside the drawer 10 can achieve the effect of separating water and debris.

[0030] Working principle: First, the workpiece is directly fixed to the top column 3 at the two sets of support frames 2, so that the top column 3 fixes the workpiece. Then, the sanding disc is fixed to the mounting rod 507 with bolts. Then, grinding can begin. During the grinding process, the drive motor 503 drives the screw 502 to rotate. The screw 502 drives the slider 501 to move laterally through the outer thread. Thus, the movement of the slider 501 drives the movement of the mounting rod 507 and the sanding disc. During the lateral movement of the slider 501, the hydraulic cylinder 505 can pull the mounting frame 504, so that the drive motor 503 at the mounting frame 504, as well as the screw 502 and slider 507 on one side of the drive motor 503, move. 01 and mounting rod 507, along with the sanding disc, move vertically to achieve precision grinding of the workpiece. During the grinding process, water pump 802 draws water from the water tank 801 to the connecting hose 803, and then to the diversion pipe 804. The diversion pipe 804 then distributes the water to the nozzle 806, allowing the water to be sprayed onto the workpiece. This water reduces the dispersion of workpiece debris and lowers the temperature of the workpiece, achieving a cooling effect. Finally, the collection chamber 9 collects the water sprayed by the spraying structure 8 and the debris generated during the grinding of the workpiece. The screen plate inside its drawer 10 separates the water from the debris.
