[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Example 1
[0023] Reference Figures 1-4 A carbide tool grinding structure includes a worktable 1. A T-shaped groove 2 is provided in front of the upper surface of the worktable 1, and there are two T-shaped grooves 2. Two T-shaped blocks 3 are slidably connected inside the two T-shaped grooves 2, and a fixing sleeve 4 is fixedly connected to the upper surface of the two T-shaped blocks 3.
[0024] A load-bearing plate 5 is inserted into the inner wall of the fixed sleeve 4. An arc-shaped fixing groove 6 is formed on the upper surface of the load-bearing plate 5. An annular locking block 7 is provided on the inner wall of the arc-shaped fixing groove 6. A limit frame 8 is provided on the outer surface of the annular locking block 7. A fixing clamp 23 is provided on the inner wall of the annular locking block 7. A first locking groove 9 is formed on the front of the fixed sleeve 4, and there are two first locking grooves 9. A second locking groove 10 is formed on the front of the load-bearing plate 5, and there are two second locking grooves 10. Two I-shaped blocks 11 are locked into the inner walls of both first locking grooves 9 and second locking groove 10. Fixing plates 12 are fixedly connected to both sides of the limit frame 8. The upper surface of the workbench 2 is threaded with a fixing bolt 13. The inner wall of the limiting frame 8 is provided with an arc groove 22. An L-shaped plate 14 is fixedly connected to the middle position of the front of the fixing sleeve 4. A fixing frame 15 is inserted into the upper surface of the L-shaped plate 14. A circular groove 16 is provided at the front of the upper surface of the workbench 1. A support column 17 is fixedly connected to the lower surface of the workbench 1. A square collecting cylinder 18 is provided at the middle position of the upper surface of the workbench 1. A load-bearing frame 19 is fixedly connected to the left side of the upper surface of the workbench 1. A drive motor 20 is fixedly connected inside the load-bearing frame 19. A grinding disc 21 is provided at the power output end of the drive motor 20.
[0025] In current technology, when regrinding carbide tools, most methods involve manually grinding the carbide tool on the surface of a grinding wheel. This method results in an uneven surface on the carbide tool, affecting the next grooving operation. Furthermore, most equipment can only regrind one carbide tool at a time, reducing regrinding efficiency and thus practicality.
[0026] When using this device, the operator first fixes the two carbide tools requiring sharpening inside the two clamps 23. Then, the operator places the two clamps 23 inside the arc-shaped fixing groove 6 on the upper surface of the load-bearing plate 5. Next, the operator places the limiting frame 8 on the upper surface of the clamps 23, so that the annular locking block 7 on the upper surface of the clamps 23 inserts into the arc-shaped groove 22 on the lower surface of the limiting frame 8. Then, the operator uses fixing bolts 13 to fix the limiting frame 8 to the upper surfaces of the load-bearing plate 5 and the clamps 23, thus limiting the clamps 23. Finally, the operator inserts the I-shaped block 11 into the slots 9 and 10. This allows the load-bearing plate 5 to be fixed inside the fixed sleeve 4. Then, the operator starts the drive motor 20, which drives the grinding disc 21 to rotate. The fixing bracket 15 on the upper surface of the L-shaped plate 14 is then pulled up, and the operator moves the fixed sleeve 4 backward, allowing the fixing clamp 23 to approach the grinding disc 21. This allows for the re-grinding of the carbide tool. The operator can then rotate the fixing clamp 23 to improve the re-grinding process and prevent uneven grinding of the carbide tool from affecting the next grooving operation. Both fixing clamps 23 can perform re-grinding work simultaneously, increasing the efficiency of re-grinding and improving practicality.
