Axial pressure detection system and method for ball screw raceway surface grinding device

Abstract

The invention discloses an axial pressure detection system and method for a ball screw raceway surface grinding device. The system includes a grinding force-adding module and an elastic deformation ring arranged in the grinding force-adding module. An axial pressure measuring module is used to measure the axial pressure exerted by the grinding force-adding module on the elastic deformation ring. The method comprises: sticking a plurality of resistance strain gauges at equal intervals around the circumference to the middle portion of the inner wall of the elastic deformation ring; rotating a threaded end cap, causing the threaded end cap to press a gasket and finally squeezing the elastic deformation ring through the gasket in the axial direction, and thus causing the resistance strain gauges adhering to the elastic deformation ring to be subjected to axial strain; causing a strain meter to transmit the detected signals to a computer processing system, rotating the threaded end cap to make the threaded end cap sequentially rotate through different angles, obtaining a group of data of a corresponding relationship between axial pressure and the rotation angle of the threaded end cap,and obtaining a measurement curve of both. According to the axial pressure detection system and method for the ball screw raceway surface grinding device, the measurement process is sensitive and rapid, a measurement result has high accuracy, and the grinding machining accuracy of the surface of the screw raceway is improved.

technical field [0001] The invention belongs to the technical field of ball screw raceway surface grinding and processing, in particular to an axial pressure detection system and a detection method of a ball screw raceway surface grinding device. Background technique [0002] The ball screw is the most critical component in the ball screw pair, and the surface processing technology of the screw is an important factor affecting the service performance of the ball screw pair such as accuracy retention and reliability. At present, the domestic ball screw raceway surface finishing process is mainly grinding process. After the screw raceway surface is ground, it can effectively improve the lead error and truncation error of the screw, and reduce the surface roughness of the raceway. During the surface grinding process of the raceway, it is difficult to detect and control the axial pressure of the grinding device, which is an important factor affecting the surface processing effec...
