The workpiece is placed on the loading plate 3. The plate 3 is then rotated clockwise to make the clamping plate 404 approach the workpiece until the two clamping plates 404 clamp the workpiece to fix the workpiece to prevent the workpiece from moving during grinding, thereby improving the grinding effect. The longitudinal plate 401 is provided with two parallel plates, and the longitudinal plate 401 is threadedly connected with the hand screw 403 through the threaded hole 402. This clamping method is simple and easy to operate. You only need to turn the hand screw 403. The side of the clamping plate 404 close to the workpiece is attached with a rubber pad, so that the clamping plate 404 is not easy to leave clamp marks when it presses against the workpiece.

[0026] The electric grinding head 5 is arranged parallel to the top of the carrier plate 3, and a slider 6 is fixedly installed on the top of the electric grinding head 5, a horizontal plate 7 is arranged on the upper end of the slider 6, and a slide groove 8 is opened inside the lower surface of the horizontal plate 7, a screw rod 9 is installed inside the slide groove 8, and the right end of the screw rod 9 is connected to the motor 10, one end of the screw rod 9 is rotatably connected to the horizontal plate 7, and the other end of the screw rod 9 is connected to the output end of the motor 10, and the slider 6 is threadedly connected to the outer side of the screw rod 9, and the screw rod 9 is driven to rotate by the motor 10. Since the slider 6 is threadedly connected to the screw rod 9, and the outer surface of the slider 6 contacts the inner wall of the slide groove 8, the slider 6 and the electric grinding head 5 have the function of moving left and right, and the electric grinding head 5 moves left and right to quickly grind the workpiece on the carrier plate 3;

[0027] The top plate 11 is arranged parallel to the top of the horizontal plate 7, and an electric push rod 12 runs through the middle of the top plate 11. The top of the longitudinal plate 401 is welded to the lower surface of the top plate 11, and a sealing rubber strip 13 is arranged on the edge of the top plate 11. The debris generated during the grinding of the workpiece is intercepted by the dust cover 2 and the top plate 11 and cannot be dispersed to the outside, thereby improving the cleanliness of the workshop and reducing the damage to the workers' bodies. The setting of the sealing rubber strip 13 fills the connection gap between the top plate 11 and the dust cover 2, improves the sealing of the dust cover 2, plays a dust-proof role, and can also well reduce noise pollution. Support frames 17 are welded on both sides of the lower surface of the workbench 1, and the two support frames 17 A base plate 16 is fixedly installed between the two surfaces, and an electric push rod 14 is installed on the upper end of the base plate 16. A circular hole 15 is opened in the middle of the workbench 1, and the output end of the electric push rod 14 passes through the circular hole 15 to pass through the workbench 1 and is fixedly connected with the carrier plate 3. The electric push rod 14 is started, and the output end of the electric push rod 14 pushes the carrier plate 3 upward through the circular hole 15 until the carrier plate 3 is pushed to the outside of the dust cover 2, so as to facilitate the collection of the processed workpiece.
