The invention relates to a reliability test device for a grinding wheel main shaft of a numerical control grinding machine. The device can simulate various different work conditions of the numerical control grinding machine, a frequency converter drives a main shaft motor to operate at different rotating speeds, a circumferential direction loading device exerts different circumferential loads, a radial loading device exerts different radial loads, fault data in the operating process is recorded, and the reliability level of the grinding wheel main shaft of the numerical control grinding machine is calculated and evaluated through the data. The reliability test device is applicable to the reliability test of the grinding wheel main shaft of the numerical control grinding machine, during the reliability design of the numerical control grinding machine, the reliability test device is used for evaluating the reliability level of the grinding wheel main shaft, and better application prospects are realized.
Description
technical field [0001] The invention relates to a reliability test device for a grinding wheel spindle of a numerically controlled grinding machine, which belongs to the fields of precision manufacturing technology and industrial automation control. Background technique [0002] CNC grinding machines are widely used in mechanical processing and manufacturing industries, using CNC programs to control servo motors to drive grinding wheels to grind shafts, planes, curved surfaces, etc. CNC grinding machines are usually the last process of precision parts processing, so the performance and reliability of CNC grinding machines have an important impact on the precision and efficiency of parts processing. [0003] Whether it is a shaft type CNC grinding machine, or a plane CNC grinding machine and a curved surface CNC grinding machine, it includes a grinding wheel spindle. The main function of the grinding wheel spindle is to drive the grinding wheel to rotate at a high speed. The...
