Abstract

The utility model relates to the technical field of motor detection, in particular to an electric actuator motor function test board, which comprises a workbench, an upper mounting plate, a lower mounting plate, a circular plastic positioning bushing and an inner conical plastic bushing, a plurality of through holes are formed in the top layer of the workbench, the upper mounting plate is erected above the through holes, and the lower mounting plate is erected above the inner conical plastic bushing. A plurality of circular plastic positioning bushings are mounted at the top of the upper mounting plate, a coupler of the motor is inserted into the circular plastic positioning bushings, an O-shaped ring on the surface of the coupler makes contact with inner holes of the circular plastic positioning bushings, a lower mounting plate is mounted at the bottom layer of the workbench, and a plurality of inner conical plastic bushings are mounted at the top of the lower mounting plate. A lead screw at the bottom of the motor penetrates through the through hole and then is inserted into the corresponding inner conical plastic lining, and the lower end of the lead screw makes contact with a conical inner hole of the inner conical plastic lining. Compared with the prior art, the installation of the motor coupler and the screw rod is realized, so that the real transmission structure of the motor is simulated, and the measurement of the forward and reverse rotation strokes of the motor is realized.
