Three-axial-force performance test device of large-push-force superconductive linear motor

Abstract

The invention discloses a three-axial-force performance test device of a large-push-force superconductive linear motor. A horizontal moving test desk and a vertical moving test desk are mounted on a main body frame; a horizontal moving test desk consists of a transverse servo motor, a longitudinal servo motor, a transverse ball screw and a longitudinal ball screw; a horizontal plate is mounted on the horizontal moving test desk; a primary linear motor is fixed on the horizontal plate; the vertical moving test desk has the structure that servo motors and ball screws are vertically mounted; two groups of linear modules are vertically fixed on the left side surface and the right side surface of the main body frame respectively; a rectangular frame is fixed on sliding blocks of four linear modules; four three-axial-force sensors are fixed between an upper plate and a lower plate of the bottom surface of the rectangular frame; a secondary linear motor is fixed on the bottom surface of the lower plate; linear displacement sensors are respectively mounted close to the three ball screws; and signals of the three-axial-force sensors are transmitted to an industrial personal computer by an amplifier and a multichannel data acquisition card. The device is used for achievement verification of theoretical research of large-push-force and large-air-gap superconductive linear motors in a laboratory at present, is simple in structure and easy to mount, and is applicable to multiple experiment environments.

Description

technical field [0001] The patent of the present invention relates to a performance test device of a three-axis force output device, specifically, a three-axis force test device for a large-thrust large-gap superconducting linear motor. Background technique [0002] As a typical three-axis force output device, the linear motor can convert electric energy into linear motion without any intermediate conversion structure, and output three-axis force with the secondary as the output end. Compared with the traditional method, the primary and secondary There can be no mechanical connection at all. [0003] In the current machinery manufacturing industry, linear motors have been widely used in manufacturing equipment such as high-speed milling machines, laser processing machine tools, grinding machines, and machining centers. The promotion and use of linear motors is also an important development direction of CNC machine tools. In military applications, there are electromagnetic ...
