Abstract

The invention provides a tool for ball screw pair outer raceway grinding and grinding force loading. The tool comprises a flexible nut, a grinding outer cover, a sensor assembly, a thread end cap, a polyurethane elastic body, a polyurethane buffering body and an outer cover base. The outer cover base is arranged at the front end of the grinding outer cover and forms a grinding cavity with the grinding outer cover, a first lead screw through hole is formed in the outer cover base, and the flexible nut is arranged in the grinding cavity and connected with a lead screw in a matched mode. The flexible nut is sleeved with the polyurethane buffering body, and the polyurethane buffering body is sleeved with the polyurethane elastic body. The inner wall of the polyurethane elastic body and the outer wall of the polyurethane buffering body are tightly matched, and the outer wall of the polyurethane elastic body and the inner wall of the grinding cavity are tightly matched. The thread end cap is provided with a second lead screw through hole and extends into the grinding cavity to be fixed from the rear end of the grinding outer cover, the sensor assembly is arranged between the thread end cap and the polyurethane elastic body and provided with tension and pressure sensors, and the pressure sensors measure the axial pressure of the thread end cap on the polyurethane elastic body.

Description

technical field [0001] The invention relates to a ball screw pair processing technology, in particular to a tool for grinding the outer raceway of the ball screw pair and loading the grinding force. Background technique [0002] The ball screw pair is a precision machine tool component. With the development of the world's manufacturing industry, the pursuit of precision and quality of machine tools has become more and more important, and the ball screw pair is just to solve the manufacturing industry's precision and reliability of machine tools. [0003] For the ball screw to meet the precision and reliability requirements of the machine tool, the precision and reliability of the screw itself are very important. This problem of precision machining of ball screws has arisen in the manufacturing industry. Generally, the machining process of ball screw is nothing more than cutting and whirling milling, but simple cutting obviously cannot guarantee the accuracy requirements of...
