Problems solved by technology

[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

Abstract

The invention discloses a torque calibration test device for an angular stroke electric actuator structure, which includes an integral support, a motor, a force arm, a pulley mechanism, a lead screw, and a weight. , lead screw, the motor is fixed on the force arm through the bracket, the force arm is connected with the overall support, the force arm can rotate a certain angle around the center, one end of the pulley mechanism is connected with the lead screw, driven by the lead screw, the pulley mechanism can be in the force arm Moving upward, the other end of the pulley mechanism is connected with the weight; the invention can drive the screw to rotate through the motor to drive the weight to move on the force arm, thereby adjusting the torque, eliminating the trouble of constantly adding and subtracting weights in order to adjust the torque , thus improving the test efficiency.

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...
