[0002] A tool is a tool used for cutting, cutting, engraving and other processing operations. Tool sharpening is an important part of the tool manufacturing or repair process. Tool sharpening is mainly to enable the tool to have cutting function. By grinding and grinding the cutting edge of the tool, a sharp cutting edge is formed so that it can easily cut and cut various materials when used. When the tool is sharpened, a special sharpening device is used, and a grinding wheel is used for high-speed grinding to achieve efficient and accurate sharpening.

[0003] In daily work, it is found that when the above-mentioned sharpening device for tool production is sharpening, the two grinding wheels are fixed on the rotating shaft, so that the distance between the two grinding wheels cannot be adjusted.

The fixed blocks 67 are inserted into the inner wall of the connecting ring 62. A connecting assembly 68 is arranged on the inner wall of the connecting ring 62. A screw 65 is rotatably connected to the inner wall of the rotating shaft 3. The screw 65 is threadedly connected with the inner walls of the two connecting rings 62. A support assembly 66 is arranged on the inner wall of the workbench 1.

[0023] In this embodiment: The screw 65 can be used to drive the two connecting rings 62 to slide in the inner wall of the rotating shaft 3, so as to adjust the distance between the trapezoidal grinding wheels 5, facilitating the sharpening operation for tools of different sizes.

[0024] Specifically, the connecting component 68 includes snap rings 682. There are three snap rings 682. The three snap rings 682 are respectively slidably connected to the inner wall of the connecting ring 62. The snap rings 682 are inserted into the inner wall of the fixed block 67. A rotating ring 681 is rotatably connected to the surface of the connecting ring 62. A connecting rod 684 is fixedly connected to the surface of the rotating ring 681. One end of the connecting rod 684 is fixedly connected to the surface of the snap ring 682.

[0025] In this embodiment: After the hollow sleeve 61 drives the fixed block 67 to be inserted into the inner wall of the connecting ring 62, rotate the rotating ring 681. The connecting rod 684 drives the snap ring 682 to move. The three snap rings 682 can be respectively inserted into the inner wall of the fixed block 67 to achieve the connection operation.

[0026] Specifically, on one side of the snap ring 682 corresponding to the inner wall of the connecting ring 62, there are three springs 683 fixedly connected. The springs 683 can provide elastic force to the snap ring 682, so that the snap block is stably inserted into the inner wall of the fixed block 67, improving the stability effect.

[0027] Specifically, one end of the rotating shaft 3 is fixedly connected to a second motor 64. The output end of the second motor 64 is fixedly connected to one end of the screw rod 65.

[0032] Working principle: When performing edge grinding adjustment, the second motor 64 can be turned on. The second motor 64 drives the screw rod 65 to rotate. The screw rod 65 drives two connecting rings 62 to slide inside the inner wall of the rotating shaft 3. When the connecting rings 62 drive the hollow sleeve 61 and the trapezoidal grinding wheel 5 to move, the scale 63 can be observed, so as to realize precise adjustment of the distance between the trapezoidal grinding wheels 5. After adjustment, the first motor 4 can be turned on. The first motor 4 drives the rotating shaft 3 and the trapezoidal grinding wheel 5 to rotate through the belt, so as to realize edge grinding of the tool. Before the rotating shaft 3 rotates, the cylinder 662 can be turned on. The cylinder 662 drives the support member 661 to move, so that the two rollers 663 in the support member 661 contact the rotating shaft 3. Thus, when the rotating shaft 3 rotates, it can play a supporting role. When the trapezoidal grinding wheel 5 needs to be replaced, first reset the support member 661, and then push the rotating ring 681 and the connecting rod 684. The connecting rod 684 drives the snap ring 682 to move, and the spring 683 is stressed. After the snap ring 682 is removed from the inner wall of the fixed block 67, the hollow sleeve 61 can be removed from the connecting ring 62, and the trapezoidal grinding wheel 5 can be removed for replacement and maintenance.
