Device and method for testing and monitoring performance of dynamic tool post by simulating loading under typical working conditions

Abstract

The invention relates to a typical condition simulated loading type power knife rest detecting monitoring method and device, and overcomes the problems that detected data cannot reflect practical performance of a knife rest, influence of different typical conditions on the performance of the power knife rest cannot be obtained, the rule of precision decline cannot be obtained, and faults of the knife rest cannot be predicted in the prior art. The power knife rest, a support part of the power knife rest, a servo knife rest part performance detecting and monitoring unit, a power output part performance detecting and monitoring unit, a dynamic cutting force loading part, a power head loading part and an automatic control part are included. The typical condition simulated loading type power knife rest detecting monitoring method comprises the following steps that the models and amount of power knife rests to be detected are determined; typical conditions, loaded in the simulated manner, of the power knife rests to be detected and performance parameters to be detected and monitored are determined; the power knife rests to be detected are fixed on the support part of the power knife rests; and performance detection and monitoring of the power knife rests are divided into four portions.

Description

technical field [0001] The present invention relates to a comprehensive performance detection and monitoring device and method for a numerically controlled machine tool rest, more precisely, the present invention relates to a performance detection and monitoring device for a power tool rest loaded based on simulated typical working conditions and its application Methods for performance testing and monitoring of devices. Background technique [0002] In recent years, with the continuous improvement of my country's numerical control technology, domestic numerical control machine tools are widely used in aviation, aerospace, shipbuilding, automobile, energy and other industries. However, there is still a big gap between domestic CNC machine tools and foreign imported machine tools, which is mainly reflected in the reliability level of CNC machine tools. The reliability level of key functional components of CNC machine tools directly affects the reliability of the whole machine....
