Spindle reliability test device and test method for automatic control of cutting force

Abstract

The invention discloses and relates to a cutting force automatic control main shaft reliability test device and a test method, and belongs to the technical field of mechanical test equipment and method. The problems that in the prior art, the real work conditions of a main shaft cannot be accurately and dynamically simulated; the control mode is complicated; the equipment manufacturing cost is high are solved. The main shaft reliability test device consists of a main shaft installing table, a cutting force automatic control device, a cutting torque loading device, state monitoring equipment and auxiliary equipment, wherein the cutting force automatic control device consists of a cutting force magnitude loading mechanism, a cutting force direction regulating mechanism, an electromagnetic locking mechanism and a loading device support frame. The test method of the main shaft reliability test device comprises the following steps: 1, obtaining and processing the load and state parameters; 2, performing detection and debugging on the cutting force automatic control main shaft reliability test device before the work; 3, the cutting force automatic control main shaft reliability test device simulates the work condition loading experiments.

Description

Technical field [0001] The invention belongs to the technical field of mechanical test equipment and methods, and relates to a spindle reliability test device that simulates the working conditions of a machine tool spindle and a test method for spindle reliability. Background technique [0002] The spindle is one of the key components of CNC machine tools, and its reliability level directly affects the reliability of the whole machine. Carrying out reliability tests on the spindle, discovering its weak links and making targeted improvements, can greatly improve the reliability of the machine tool. Therefore, a large number of reliability tests for machine tool spindles have been conducted at home and abroad. However, in the process of reliability testing of machine tool spindles, very few test devices can approximate real operating conditions. In the design of the loading device, most test benches at home and abroad can only realize the dynamic control of the cutting force in t...
