Abstract

The invention discloses a method for testing reliability of an electro-hydraulic-magnetic-hybrid-loaded servo power tool rest. An electro-hydraulic and magnetic hybrid loading servo power tool rest reliability test platform comprises a console, a tool rest, a hydraulic system, a common tool bit loading system, a loading system base and a power head loading system. A servo power tool rest transposition test, a servo power tool rest common tool bit loading test, a servo power tool rest 90-degree loading test and a servo power tool rest 180-degree loading test are carried out; the power head loading system can realize conversion between 90-degree power head loading and 180-degree power head loading; a dynamic load is loaded and applied and a dynamic load condition is detected; the dynamic force application condition is detected and recorded through a displacement sensor and a force detection coil, and the torque application condition is obtained through an electric dynamometer.

Description

technical field [0001] The invention belongs to the technical field of numerical control mechanical testing equipment and methods, in particular to a method for testing the reliability of a servo-powered tool holder with electro-hydraulic and magnetic hybrid loading. 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. Throughout the current reliability test benches for CNC tool holders at home and abroad, most of them are reliability test devices for ordinary cutting tool holders, a few reliability test devices with single power heads, and reliability devices for multi-power head tool holders. There are few, and it is impossible to reliably load the multi-power head and the ordinary loading head at the same time. As the market demand for multi-power head tool holders gradually increases, the reliability test device for multi-power head servo-powered ...
