Full-automatic torque repetition deviation measuring system

Abstract

The invention relates to a full-automatic torque repetition deviation measuring system. The system comprises: a PLC central processing unit, a torque acquisition circuit, a magnetic powder loading circuit, a bus, a starting button, an electric actuating mechanism control circuit. The PLC central processing unit is respectively connected with the starting button, the torque acquisition circuit, the magnetic powder loading circuit and the electric actuating mechanism control circuit through the bus. The magnetic powder loading circuit is connected with the torque acquisition circuit through a test bench. By using the current electric actuating mechanism to debug, a direct measuring function of the torque repetition deviation is not possessed; credibility can be declined caused by artificial factors, such as selectivity processing during measuring and reading a torque value, artificial calculating technology processing and the like and many other defects can be generated. By using the system of the invention, the above defects can be solved. In the invention, through one button, the torque repetition deviation can be measured automatically and an RS485 interface is possessed so as to print or upload. A circuit is highly compact. Reliability of the system is strong. Under the support of related programs, closed-loop intelligent control can be realized. The system possesses perfect functions. And simultaneously, production costs can be reduced.

Description

technical field [0001] The invention relates to an automatic torque measurement system of an electric actuator, in particular to a fully automatic torque repeat deviation measurement system. Background technique [0002] The existing electric actuator debugging platform has the function of torque measurement, but the repeated deviation of the torque of the electric actuator needs to be measured three times, and the data of the three times should be recorded, and manual calculation is performed according to the calculation requirements of the repeated deviation, which does not meet the measurement data. According to the relevant regulations, the work efficiency is low, especially the manual calculation is mistaken for technical processing, which cannot meet the requirements of the current industrial automation production, and it is urgent to have a special measurement device for torque repeat deviation. Contents of the invention [0003] In order to solve the above problems...
