A reliability test method of multi-working condition simulated loading servo-powered tool holder

Abstract

The invention discloses a method for testing the reliability of a multi-working condition simulated loading servo power tool rest, which includes: a servo power tool rest indexing test, a multi-working condition multi-stage parallel loading test of a servo power Head loading test; using multi-working conditions to simulate loading servo power tool holder reliability test platform, which includes: console, tool holder, tool holder seat, dynamometer, dynamometer device seat, loading device frame, hydraulic system; loading The rotating base of the device can realize a variety of machining and cutting loads, as well as the full working condition test and the monitoring and closed-loop control of the loading force; the dynamometer loads the tool holder, and the cutting torque and speed can be monitored and closed-loop controlled to improve the control of the loading device Accuracy, while comparing the load application of four dynamometers.

Description

technical field [0001] The invention belongs to the technical field of numerical control mechanical testing equipment and methods, and in particular relates to a multi-working-condition simulation loading servo power tool holder reliability testing method. Background technique [0002] As the key functional component of CNC lathe, the CNC tool post's failure directly affects the machining accuracy and work efficiency of the lathe. Looking at the current reliability test benches of CNC tool holders at home and abroad, most of them can only conduct single-condition reliability tests on a single CNC tool holder. Although some test benches can perform multi-condition tests, the working conditions they can perform The simulation situation is very limited and the load simulation effect is poor. The numerous loading devices and accessories lead to high cost of the test bench and low space utilization. For the loading of the power head of the power servo tool holder, most of the te...
