Device for detecting comprehensive performance of ball screw assembly in loaded state

Abstract

A device for detecting comprehensive performance of a ball screw assembly in a loaded state comprises a testboard machine body fixed on a cast iron platform, wherein a servomotor is arranged at one end of the testboard machine body; the output shaft of the servomotor is connected to one end of the ball screw assembly through a first coupler, a dynamic torque sensor and a second coupler; an eddy current sensor and a rotary encoder are arranged at the other end of the testboard machine body; a grating scale and an infrared temperature sensor are arranged on the testboard machine body; a rolling guide rail is arranged on the testboard machine body, and is provided with an analog working table; the analog working table is connected to the rolling guide rail through a rolling guide rail slide block, and is connected to a loading device; a ball screw assembly nut is arranged on the analog working table through a nut support base. The device is stable in properties, quick in movement and testing response speed, comprehensive and accurate in testing performance parameters, and simple in structure, and can realize the comprehensive performance detection of ball screw assemblies with different models in no-loaded states or loaded states.

Description

technical field [0001] The invention belongs to the field of a comprehensive performance detection device of a high-speed precision transmission pair, in particular to a device for detecting the comprehensive performance of a ball screw pair under a loaded state. Background technique [0002] In recent years, the rapid development of important industries such as aerospace, national defense, shipbuilding, electric power, energy and automobiles in my country has put forward high requirements for the performance of various mechanical processing equipment. But generally speaking, there is still a big gap between the development level of my country's equipment manufacturing industry and industrialized countries such as the United States, Germany, and Japan. Many key technologies and functional components are still blank in China, and a considerable part is used for high-speed equipment. , High-end CNC machine tools for high-precision processing, and key functional components requi...
