Power servo tool rest power head reliability test bench for all-condition simulation

Abstract

The invention is suitable for the technical field of mechanical test equipment, and provides a power servo tool rest power head reliability test bench for all-condition simulation. The power servo tool rest supporting mechanism is used for adjusting the height of the power head and comprises a power servo tool rest base and a power servo tool rest base plate located on the power servo tool rest base, and the power servo tool rest base is arranged on the horizontal iron; the power servo tool rest power head loading mechanism is used for applying dynamic cutting force to the power head and comprises a magnetofluid bearing loading device, a multi-angle hydraulic loading device and an axial loading mechanism; the power servo tool rest power head radial run-out detection device is innovative in structure, and the test reliability can be improved.

Description

technical field [0001] The invention relates to the technical field of mechanical test equipment, in particular to a reliability test bench for a power head of a power servo tool post simulating all working conditions. Background technique [0002] As the mother machine of the equipment manufacturing industry, the development level of CNC machine tools determines the development of the entire national equipment manufacturing industry and is a national strategic equipment. From the processing and manufacturing of basic components to the manufacturing of large-scale machinery and equipment, CNC machine tools play an irreplaceable role in all fields of manufacturing. After 30 years of development of machine tools in my country, CNC machine tools have achieved significant progress in accuracy, speed and function, greatly narrowing the gap with developed countries, and gradually forming a certain competitiveness in the international market, but its reliability level It is still f...
