Abstract

The invention discloses a torque calibration testing device for an angular travel electric actuator. The torque calibration testing device comprises an overall support, motors, a force arm, pulley mechanisms, lead screws and weights. The angular travel electric actuator is connected with a driving hole in the middle of the force arm through an adapter driving sleeve, the lead screws and the motors are fixed to the force arm through the overall support, the force arm is connected with the overall support and can rotate by a certain angle around the center of the force arm, one ends of the pulley mechanisms are connected with the lead screws, the pulley mechanisms can move on the force arm under driving of the lead screws, and the other ends of the pulley mechanisms are connected with the weights. According to the torque calibration testing device, the lead screws can be driven by the motors to rotate to accordingly drive the weights to move on the force arm, the torque is accordingly adjusted, the trouble caused by the fact that the weights are continuously added or removed to adjust the torque is avoided, and therefore the testing efficiency is improved.

Description

technical field [0001] The invention relates to a torque calibration test device, in particular to a torque calibration test device for an angular stroke electric actuator. Background technique [0002] Electric actuators must be comprehensively tested before leaving the factory, including torque testing. Most actuator manufacturers use the original mechanical method of levers and weights when calibrating torque, which is cumbersome to operate. Different weights are obtained from time to time, back and forth, time-consuming and labor-intensive. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the background technology, and provide an electric actuator torque calibration test device with the advantages of simple structure, easy operation, improved calibration efficiency, time-saving and labor-saving advantages. [0004] The technical solution of the present invention is: a torque calibration test dev...
