Integrated test stand of straight-travel electric actuating mechanism

Abstract

An integrated test stand of a straight-travel electric actuating mechanism comprises an S-type force sensor, a digital display displacement measuring instrument, a magnetic powder brake, a gear rack group and a console; and the integrated test stand also comprises an installation seat; one end of the S-type force sensor is a connection end of an output shaft of the electric actuating mechanism; the other end of the S-type force sensor is connected with a rack in the gear rack group, the rack movably runs on a rack seat along the force measuring direction of the S-type force sensor, and the rack seat is fixedly installed on the installation eat; a gear in the gear rack group which is matched with the rack is installed on a gear shaft, the end part of a gear shaft is supported on a bearing seat, and the bearing seat is fixedly installed on the installation seat; the gear shaft is connected with an output shaft of the magnetic powder brake through a coupler; the measurement end of the digital display displacement measuring instrument is correspondently connected with the output shaft of the electric actuating mechanism; and the console receives data of the S-type force sensor and the data of the digital display displacement measuring instrument to be processed and outputted and supplies a voltage power supply signal and a current control signal to the electric actuating mechanism and the magnetic powder brake. Due to the adoption of the integrated test stand, the detection of the thrusting force and the displacement of the straight-travel electric actuating mechanism can be realized, the detection range is wide, the detection precision is high, and real-time online detection can be realized.

Description

technical field [0001] The invention relates to a comprehensive testing system for an electric actuator, in particular a comprehensive testing device suitable for parameter testing of a straight-stroke electric actuator. Background technique [0002] For industrial electric actuators, torque and displacement are very important parameters. However, the demand for these two parameters is more urgent in the sample test stage of the electric actuator. Accurate, reliable, and convenient measurement of the real-time and maximum values ​​of torque and displacement is of great help to improve and enhance the performance of electric actuators. [0003] At present, the thrust test of linear electric actuators mostly adopts the traditional weight-hanging detection method through the lever plus weight or the hydraulic oil pressure of the hydraulic pump as the load method, which limits the measurement range and is difficult for large thrust. Realization; and the detection of the displa...
