Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] see figure 1 As shown in -2, the present invention includes a cast iron platform 40 and a test bench body 27 that can be installed with two kinds of different width guide rails. The cast iron platform 40 is provided with a T-shaped slot, and the test bench body 27 is fixed to the cast iron body with bolts through the T-shaped slot. On the platform 40, and between the test bench fuselage 27 and the cast iron platform 40, a machine tool adjustment horn 39 is set. Adjust the horizontality of the test bench as a whole through the level meter and the machine tool to adjust the pad iron 39 .

[0025] see image 3 , one end of the test bench body 27 is equipped with a servo motor 1 that provides a power source, and the output shaft of the servo motor 1 passes through the first coupling 2, the dynamic torque sensor 3 and the second coupling 4 and one end of ...

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...
