[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figures 1-5 The workpiece grinding machine shown includes a base plate 1. A U-shaped frame 3 is movably mounted on the top of the base plate 1 via a sliding assembly. Grinding rollers 7 are rotatably mounted between the inner walls of the two sides of the U-shaped frame 3. A second motor 8 is fixedly mounted on the side of the U-shaped frame 3. The output end of the second motor 8 is connected to the grinding rollers 7. A dust-reducing assembly is mounted on the top of the U-shaped frame 3. A clamping assembly is mounted on the top of the base plate 1.

[0026] The clamping assembly includes two hydraulic cylinders 9, which are fixedly mounted on the top of the base plate 1. The two hydraulic cylinders 9 are symmetrically distributed about the center line of the base plate 1. A lifting plate 10 is fixedly connected between the telescopic ends of the two hydraulic cylinders 9. A fixed clamping plate 11 and a side plate 13 are fixedly mounted at the two ends of the top of the lifting plate 10, respectively. Two symmetrically distributed electric push rods 14 are fixedly mounted on the side of the side plate 13. A movable clamping plate 12 is fixedly connected between the telescopic ends of the two electric push rods 14. The movable clamping plate 12 and the lifting plate 10 are movably fitted together. The lifting plate 10 is located below the grinding roller 7.

[0027] The sliding assembly includes two symmetrically distributed sliding grooves, which are fixedly opened on the upper surface of the base plate 1. A lead screw 2 is rotatably installed inside the sliding groove. The lower end of the U-shaped frame 3 extends movably into the interior of the sliding groove and is threadedly connected to the lead screw 2. A housing 4 is fixedly installed on the side of the base plate 1. A pulley is fixedly installed at one end of the lead screw 2 that extends movably into the housing 4. A first motor 5 is fixedly installed inside the housing 4. The output end of the first motor 5 is fixedly connected to one of the pulleys. A synchronous belt 6 is rotatably installed between the two pulleys. The lower end of the U-shaped frame 3 is adapted to the sliding groove.

[0028] Specifically, in the initial state of use, the U-shaped frame 3 is located at the rightmost end of the slide groove. The flat workpiece is then placed between the fixed clamping plate 11 and the movable clamping plate 12. The two electric push rods 14 are activated to move the movable clamping plate 12, clamping the flat workpiece between the fixed clamping plate 11 and the movable clamping plate 12. Depending on the thickness of the flat workpiece, the two hydraulic cylinders 9 are activated to move the lifting plate 10 up and down, thereby adjusting the distance between the flat workpiece and the grinding roller 7 to achieve a suitable spacing. Then, the first motor 5 is activated, and through the synchronous belt 6, the two lead screws 2 are driven to rotate synchronously, thereby moving the U-shaped frame 3. At the same time, the second motor 8 is activated to drive the grinding roller 7 to rotate, so that the grinding roller 7 grinds and polishes the flat workpiece from right to left. After grinding is completed, the U-shaped frame 3 is reset, and the two electric push rods 14 are activated in the opposite direction to release the flat workpiece, allowing the ground flat workpiece to be removed.

[0029] In summary, this invention enables the flat workpiece to be well fixed during grinding, solving the problem that existing vertical machining center grinding devices cannot clamp and fix the workpiece during grinding and polishing, resulting in poor grinding effect.

[0030] In addition, this invention can also be applied to the grinding and polishing of flat workpieces of different thicknesses, eliminating the hassle of manually changing the grinding roller 7 and improving grinding efficiency.

[0031] Furthermore, the two sides of the lifting plate 10 are respectively in contact with the inner walls of the two sides of the U-shaped frame 3. This setting limits the position of the lifting plate 10, allowing it to move up and down stably.

[0032] Furthermore, the dust suppression assembly includes a top plate 15 fixedly mounted on the top of the U-shaped frame 3. A vacuum cleaner 16 and a dust collection box 17 are mounted on the top of the top plate 15. The vacuum cleaner 16 and the dust collection box 17 are connected to each other through an air outlet pipe. An air inlet pipe is fixedly mounted on the side of the dust collection box 17. Two symmetrically distributed main pipes 22 are fixedly mounted at the end of the air inlet pipe. Extension rods 18 are fixedly mounted at the four corners of the bottom of the top plate 15. A dust suction hood 19 is fixedly mounted between the lower ends of the two extension rods 18 on the same side. The vertical cross-section of the dust suction hood 19 is conical. Several equally spaced branch pipes 20 are fixedly mounted on the top of the dust suction hood 19. A diversion pipe 21 is fixedly connected between the upper ends of the multiple branch pipes 20. The end of the main pipe 22 away from the air inlet pipe passes through the lower surface of the top plate 15 and is fixedly connected to the middle of the diversion pipe 21.

[0033] Specifically, when the grinding roller 7 is grinding and polishing the flat workpiece, the vacuum cleaner 16 is started. The external air carries the grinding dust through the dust hood 19, branch pipe 20, diversion pipe 21, main pipe 22 and air inlet pipe, and enters the dust collection box 17. After the grinding dust is filtered by the dust collection box 17, it is discharged through the air outlet pipe and the vacuum cleaner 16, thereby purifying the working environment and ensuring the safety of workers. The dust collection box 17 can be cleaned regularly. In addition, by setting up two dust hoods 19, the grinding dust on both sides of the grinding roller 7 is removed simultaneously, improving the efficiency of grinding dust removal.

[0034] Furthermore, the bottom of the dust hood 19 is higher than the bottom of the grinding roller 7, and there is a gap between the dust hood 19 and the grinding roller 7. This arrangement avoids contact between the dust hood 19 and the flat workpiece, and also avoids collision between the dust hood 19 and the grinding roller 7.

[0035] Working Principle: In the initial state of use, the U-shaped frame 3 is located at the rightmost end of the slide groove. The flat workpiece is then placed between the fixed clamping plate 11 and the movable clamping plate 12. Two electric push rods 14 are activated, causing the movable clamping plate 12 to move and clamp the flat workpiece between the fixed clamping plate 11 and the movable clamping plate 12. Depending on the thickness of the flat workpiece, two hydraulic cylinders 9 are activated, causing the lifting plate 10 to move up and down, thereby adjusting the distance between the flat workpiece and the grinding roller 7 to achieve a suitable spacing. Then, the first motor 5 is activated, and through the synchronous belt 6, it drives the two lead screws 2 to rotate synchronously, thereby moving the U-shaped frame 3. Simultaneously, the second motor 8 is activated, driving the grinding roller 7 to rotate, thus causing the grinding roller 7 to move from right to left. The left side is used to grind and polish the flat workpiece. When the grinding roller 7 is grinding and polishing the flat workpiece, the vacuum cleaner 16 is started. The external air carries the grinding dust through the dust hood 19, branch pipe 20, diversion pipe 21, main pipe 22 and air inlet pipe, and enters the dust collection box 17. After the grinding dust is filtered by the dust collection box 17, it is discharged through the air outlet pipe and the vacuum cleaner 16, thereby purifying the working environment and ensuring the safety of workers. The dust collection box 17 can be cleaned regularly. In addition, the two dust hoods 19 are set to remove the grinding dust on both sides of the grinding roller 7 at the same time. After grinding is completed, the U-shaped frame 3 is reset, and the two electric push rods 14 are started in reverse to release the flat workpiece, so that the ground flat workpiece can be removed.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
