Abstract

The invention discloses a numerical control capstan turret reliability testing system with an electro-hydraulic servo loading device, aiming to overcome the detect that the traditional equipment cannot be used for simulating real cutting force to carry out a loading test on a numerical control capstan turret. The system comprises a pump station, a hydraulic loading mechanism (I), a numerical control capstan turret control part (II) and an electro-hydraulic servo loading control part (III), wherein the hydraulic loading mechanism (I) comprises a stressing rod (3) and an oil cylinder (16); the numerical control capstan turret control part (II) comprises a programmable controller (20); the electro-hydraulic servo loading control part (III) comprises a pressure sensor (4), a displacement sensor (8) and an electro-hydraulic servo valve (17); the hydraulic loading mechanism (I) and the numerical control capstan turret control part (II) are arranged on a workbench (18); the numerical control capstan turret control part (II) is arranged on the outer wall of the oil cylinder (16); and the electro-hydraulic servo loading control part (III) and the oil cylinder (16) are connected with the pipeline of the pump station.

Description

technical field [0001] The invention relates to a reliability test system of a numerical control turret tool rest of a numerical control machine tool, in particular to a reliability test system of a numerical control turret tool rest with an electro-hydraulic servo loading device. Background technique [0002] With the rapid development of the equipment manufacturing industry, my country has become a major player in the production and application of CNC machine tools. According to investigations and research, there is still a big gap between domestic CNC machine tools and developed countries in terms of quality and reliability. The level and capacity of my country's equipment manufacturing industry. CNC tool post is a key functional component of CNC machine tools. Its reliability level plays a key role in improving the reliability of the whole machine. The reliability research of CNC tool post needs to be based on fault data, but the on-site tracking test of the tool post is ...
