During the test, the outer shell of the motor to be tested is placed on the top of the placement plate (12), with one end in contact with the surface of the limiting plate (211). The cylinder (221) is extended, which drives the drive rods (23) on both sides of the cylinder (221) to swing around the axis of the rotating shaft (22), thereby driving the first connecting rod (214) at the top of the placement plate (12) to move inward, pushing the first clamping block (28) and the second clamping block (29) to move relative to each other, squeezing the motor to be tested so that it can be quickly installed and positioned. Step 2: After the motor under test is installed and positioned, take the test ring (31) and put it on the output shaft surface of the motor under test. Control the drive motor (35) to work and drive the gear shaft (36) to rotate. The rotation of the gear shaft (36) drives the gear (37) to rotate. Thus, under the condition of meshing, the gear (37) rotates and drives the gear ring to rotate. When the gear ring rotates, it drives the drive groove (38) on the surface to rotate. Then, under the limit ring (32), when the angle of the drive groove (38) changes, it drives multiple sliding blocks (39) on the surface to move to one side at the same time. Then, it controls the surface of multiple clamping blocks (310) to press against the arc surface of the output shaft to clamp and position it. Step 3: After the detection ring (31) is installed, the arc surface of the detection ring (31) is pressed to compress the control spring (47) of the detection rod (41). When it stops, the control displacement sensor (44) is set to zero, and the motor under test is powered on and driven to rotate, thereby driving the detection ring (31) to rotate. When the output shaft of the motor under test drives the detection ring (31) to rotate, observe the change in the value of the displacement sensor (44). If the displacement value does not change, it means that the output shaft of the motor under test does not shake and the motor under test is qualified. If the displacement value of the displacement sensor (44) changes greatly, it means that the output shaft of the motor under test is deformed and causes rotational shaking, and the motor under test is unqualified.
