A support arm 11 is fixedly sleeved on the rotating shaft. An angle adjustment motor 12 is installed at the end of the support arm 11 away from the rotating shaft. The output shaft of the angle adjustment motor 12 is driven and connected to a rotating seat 13. A fixing block 14 is fixedly connected to the rotating seat 13. A cylinder 15 is installed on the rotating seat 13. A moving block 16 is fixedly connected to the driving end of the cylinder 15. A first arc-shaped clamping surface 161 and a second arc-shaped clamping surface 141 are respectively opened on the opposite side of the moving block 16 and the fixing block 14. The first arc-shaped clamping surface 161 and the second arc-shaped clamping surface 141 are arranged facing each other.

[0018] The workbench 1 is provided with a first slide groove 101; the first displacement driving mechanism includes a first lead screw 17 disposed in the first slide groove 101 and a first lead screw motor 18 that drives the first lead screw 17 to rotate. A first slide block 19 is threadedly connected to the first lead screw 17, and the mounting base 2 is fixedly connected to the first slide block 19.

[0019] The column 4 is provided with a lifting groove 401; the lifting mechanism includes a lifting screw 20 rotatably disposed in the lifting groove 401, a lifting motor 21 for driving the lifting screw 20 to rotate is installed on the column 4, a lifting seat 22 is threadedly connected to the lifting screw 20, and the mounting bracket 5 is fixedly connected to the lifting seat 22.

[0020] The workbench 1 is provided with a second slide groove 102, which is parallel to the first slide groove 101; the second displacement driving mechanism includes a second lead screw 23 disposed in the second slide groove 102 and a second lead screw motor 24 that drives the second lead screw 23 to rotate, and a second slide block 25 is threadedly connected to the second lead screw 23, and the material box 8 is fixedly connected to the second slide block 25.

[0023] Two sets of moving blocks 16 and cylinders 15 are provided, and the two sets of moving blocks 16 and cylinders 15 are symmetrically arranged. The two sets are convenient for working on the mounting base 2 side, where the processed tool 29 can be removed first and the tool to be processed 29 can be installed on the three-jaw chuck 3. When working on the material box 8 side, the processed tool 29 can be placed into the material box 8 first and then the tool to be processed 29 can be removed from the material box 8. The two tools 29 can be clamped between the fixed block 14 and the moving block 16 at the same time, which facilitates circulation and reduces the number of times the support arm 11 goes back and forth between the mounting base 2 and the material box 8.

[0024] Working principle:

[0025] The second lead screw motor 24 drives the second slide block 25, moving the material box 8 to the designated position. The third lead screw motor 27 drives the third slide block 28, moving the support frame 9 closer to the material box 8. The rotary motor 10 drives the support arm 11 to rotate, and the angle adjustment motor 12 adjusts the angle of the rotating seat 13, aligning the fixed block 14 and the moving block 16 with the tool 29. The cylinder 15 pushes the moving block 16, clamping the tool 29 through the first arc-shaped clamping surface 161 and the second arc-shaped clamping surface 141. Then, the third lead screw motor 27 drives the third slide block 28 closer to the mounting base 2, the rotary motor 10 drives the support arm 11 to rotate, and the angle adjustment motor 12 adjusts the angle of the rotating seat 13, moving the tool 29 to the three-jaw chuck 3 of the mounting base 2. After the three-jaw chuck 3 clamps the tool 29, the cylinder drives the moving block 16 to release and retract.

[0026] The first lead screw motor 18 drives the first slide 19 to move, which in turn moves the mounting base 2 horizontally, adjusting the relative position of the tool 29 and the grinding wheel 6. The lifting motor 21 drives the lifting motor 22 to lift the mounting frame 5, adjusting the height of the grinding wheel 6. The grinding motor 7 drives the grinding wheel 6 to rotate, grinding the tool 29. At the same time, the rotating mechanism drives the three-jaw chuck 3 to rotate, achieving all-round grinding of the tool 29.

[0027] After processing is completed, the support frame 9 moves to the three-jaw chuck 3 again, clamps the processed tool 29 and removes it, and transfers it to the material box 8 for placement. The material box 8 is moved out by the second displacement drive mechanism, completing one processing cycle.

[0028] This invention achieves full automation of the cutting tool process from loading and processing to unloading through the coordinated operation of multiple sets of drive mechanisms and clamping devices, greatly reducing manual intervention, improving production efficiency, and lowering labor costs.
