[0002] Diamond grinding disc is a high-efficiency grinding tool made of diamond as abrasive and combined with base material through special process. Diamond has high hardness and good wear resistance, which makes diamond grinding disc have significant advantages in precision cutting, grinding and polishing of hard and brittle materials such as cemented carbide, ceramics, glass and stone. At present, when processing diamond grinding disc, it is necessary to use a special diamond grinding disc clamping structure to clamp and fix it;

[0003] The existing clamping structure for diamond grinding discs usually adopts a screw as a drive when clamping and fixing the diamond grinding disc. When the screw rotates, it is affected by the threaded connection relationship to drive two sliders restricted by the slide groove to move relative to each other, thereby clamping the diamond grinding disc. However, the clamping method of this type has limited functions. When it is necessary to turn over or adjust the clamping position of the diamond grinding disc, the clamping structure needs to be opened to adjust the diamond grinding disc, and each adjustment requires operation. Secondly, there are also clamping structures that can be turned over, but when clamping, it is necessary to manually hold the diamond grinding disc for assistance, and then the clamping blocks on both sides move relatively to clamp it, resulting in low work efficiency.

[0023] The working principle of the clamping structure for a diamond grinding disc provided by the utility model is as follows: first, the height of the support plate 402 is adjusted according to the thickness of the diamond grinding disc to be clamped, and the support plate 402 can be adjusted by rotating it counterclockwise or clockwise. After the adjustment is completed, the diamond grinding disc is placed on the support plate 402, and then the external single-chip microcomputer controls the two electric push rods 200 to operate synchronously. The telescopic end of the electric push rod 200 moves to drive the arc clamping block 201 and the motor 202 to move synchronously. Since the opening of the arc clamping block 201 is tilted from the inside to the outside toward its center, Thereby, the two arc-shaped clamping blocks 201 finally clamp the diamond grinding disc.

The output shaft of the second motor 302 rotates to drive the diamond grinding disc to move synchronously, so as to turn the diamond grinding disc The clamping part moves out of the arc-shaped clamping block 201. After adjustment, the external single-chip microcomputer controls the telescopic ends of the two electric push rods 200 to reset, and the diamond grinding wheel can be automatically adjusted without fully opening the clamping mechanism, which greatly improves the work efficiency. After the processing is completed, the external single-chip microcomputer controls the electric telescopic rod 405 to operate in the reverse direction, and the telescopic end of the electric telescopic rod 405 retracts to drive the swing arm 401 and the support plate 402 to rotate counterclockwise, thereby resetting the support plate 402, and then the external single-chip microcomputer controls the operation of the remaining electrical components, and each mechanism is reset to release the processed diamond grinding wheel.
