Pneumatic actuator comprehensive performance test platform

Abstract

The invention relates to an overall performance testing platform for a pneumatic actuating mechanism, and belongs to the technical field of intelligent robots. The overall performance testing platform for the pneumatic actuating mechanism comprises a platform frame formed by a square angle iron bracket, supporting pillars, fixing beams and the like, photoelectric sensors, a pressure transmitter, a strain electric bridge conditioning module, an impact force sensor, an electric charge converter, a two-position five-way solenoid directional valve, an auxiliary circuit, a PCI acquisition card, a 24V direct current power source, a voltage conversion module and binding post rows. The body of the platform frame is formed by splicing aluminum alloy profiles, and the square angle iron bracket is fixed on the bottom of the platform frame to enhance the stability of the platform frame. The pneumatic actuating mechanism to be tested is made to work normally and move back and forth by controlling a solenoid valve to be connected and disconnected in a circulation mode. Meanwhile, the moving speed, the air pressure, the impact force of the pneumatic actuating mechanism and the strain and other data of the platform frame are collected by all sensors and transmitted to a testing program. The overall performance testing platform for the pneumatic actuating mechanism is capable of well measuring multiple items of the data in the working process of the pneumatic actuating mechanism, and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of intelligent robots, and in particular relates to a comprehensive performance testing platform for pneumatic actuators. Background technique [0002] In the process of agricultural machinery development, it is often necessary to carry out the fatigue life test of the whole machine. In China, Wuhan has developed a high-speed axial force drive mechanism experimental platform, which can measure dynamic performance parameters such as the speed, torque, and magnetic field gap of the active and passive rotors under different magnetic fields, and has realized the dynamic performance of large-gap magnetic transmission. Research. Nanjing has developed a performance testing platform for the IPMC compliant hand grip actuator. The experimental platform uses laser displacement sensors, digital cameras, LabVIEW virtual experimental devices and precision electronic scales for data collection and measurement, and through...

Problems solved by technology

[0003] At present, many test platforms at home and abroad are developed for the series of products they produce, so they have strong pertinence and cannot be applied to pneumatic actuators. Domestic test platform research is in its infancy, and some foreign general tests The platform is difficult to be widely used due to its high price
