The surface quality of the inner ring of the set screw bushing directly affects its assembly accuracy and service performance. Therefore, high-precision grinding of its inner ring is a key link in the production process.

[0004] The existing grinding devices for the inner ring of the set screw bushing have the following problems in practical applications; 1. Traditional grinding devices usually adopt a single-axis grinding method, which is difficult to ensure uniform grinding of the inner ring surface, and it is easy to have local over-grinding or omission, affecting the quality of the workpiece; 2. Existing equipment is difficult to adapt to the grinding requirements of set screw bushings of different sizes and specifications. Replacing and adjusting the equipment takes a long time, affecting production efficiency; 3. The heat and debris generated during the grinding process are likely to cause workpiece deformation, grinding head wear, and equipment blockage. The existing cooling and debris collection systems have low efficiency, and it is difficult to achieve the recycling of coolant and the effective separation of debris. In addition, the flying debris and coolant during the grinding process pose a threat to the safety of operators, and there is a lack of effective protection measures; 4. Existing equipment lacks universality when fixing set screw bushings of different sizes and specifications, and it is necessary to frequently replace or adjust the equipment, increasing the production preparation time and cost.

The mounting block 404 rotates through the first bidirectional screw 403 to open and close inside the slide rail bracket 402, and can be adjusted according to the model of the inner ring of the locking bushing for use; S4: Finally, when the grinding shaft 406 is working, the coolant in the water tank body 202 is ejected through the conduit 5 and the pump body acting on the nozzle 502, aiming at the grinding area, effectively reducing the temperature during the grinding process, preventing the workpiece from overheating and deforming or the grinding head from wearing, ensuring the grinding quality and accuracy, and at the same time preventing the splashing of debris to protect the staff. The processing seat 301 is evenly provided with through holes 701 to send the liquid containing debris and coolant into the filter screen frame 601 through the blanking housing 9, separating the used coolant and debris, and sending the coolant back into the water tank body 202 for reuse again, reducing the waste of coolant.
