[0002] In modern manufacturing, machine tools play a vital role, especially for the processing of precision parts, such as workpiece grinding. In this field, grinding accessories are key consumables, and their status directly affects the processing accuracy and efficiency. During long-term use, the surface of grinding accessories will gradually wear out due to continuous friction with the workpiece, causing the surface of the grinding accessories to become uneven, thus affecting the grinding quality and efficiency.

[0003] The traditional solution is to replace the grinding accessories with new ones when their performance has obviously declined. However, this method is not only costly but also causes a huge waste of resources. Alternatively, the operator manually repairs the grinding accessories. However, the strength, angle and feed speed of each manual repair may vary depending on the operator's feel, which will make the texture and roughness of the surface of the grinding accessories uneven and inefficient. Manual trimming when the grinding accessories are rotating at high speed may easily cause debris to fly if operated improperly, causing harm to the operator. Utility Model Content

The angle adjustment device 3 is used to adjust the angle of the rotary grinding device 1, thereby adjusting the grinding angle of the grinding accessories to the workpiece to meet higher grinding requirements. A multi-axis moving device 6 is provided on one side of the rotary grinding device 1, and a grinding device 2 set at a certain angle is fixedly installed on the multi-axis moving device 6. The utility model drives the grinding device 2 to move longitudinally and vertically through the multi-axis moving device 6, and the grinding device 2 is used to install a dressing wheel corresponding to the grinding accessory. When the grinding accessories have polished the workpiece many times, their surface will be worn due to friction, resulting in a decrease in the flatness of the surface of the grinding accessories and a weakening of the grinding performance. In order to ensure the quality and efficiency of the grinding of the workpiece, the grinding accessories need to be ground or replaced regularly. However, if new grinding accessories are directly replaced, it will lead to excessive waste. Therefore, the worn grinding accessories are ground and trimmed by the grinding device 2 to restore the original shape and sharpness of the grinding accessories. Only when the grinding accessories are worn to a certain extent and their effective grinding ability can no longer be restored by grinding, new grinding accessories are replaced. There is no need to frequently replace grinding accessories and manually grind and trim the grinding accessories, which reduces waste, improves operation safety, and improves the trimming effect and trimming efficiency of grinding accessories.
