[0049] The correction structure 4 also includes a thrust assembly, which is arranged on the top of the storage plate 22. The thrust assembly includes a multi-stage electric telescopic rod three 28, which is arranged on the top of the storage plate 22, and one end of the multi-stage electric telescopic rod three 28 is fixedly connected to a push plate one 29.

[0050] The thrust assembly can push the motor to be tested, and the push plate 29 cooperates with the baffle 9 to limit the two ends of the motor.

[0051] The inserting plate 32 and the hollow plate 19 are adaptively matched, and the second limiting plate 17 and the storage plate 22 are adaptively matched.

[0052] The inserting plate 32 is inserted into the inner side of the hollow plate 19 under the action of the electric push rod 30 .

[0053] When the inserting plate 32 and the hollow plate 19 are connected, the horizontal heights of the auxiliary roller 2 18 on the top of the limiting plate 2 17 and the auxiliary roller 3 23 on the top of the storage plate 22 are adaptively matched.

[0054] The motor moves on the surfaces of the auxiliary rollers 2 18 and 3 23 when the multi-stage electric telescopic rod 3 28 cooperates with the push plate 1 29 .

[0055] The bottom plate 7, the other end of the multi-stage electric telescopic rod 21 and the convex plate 33 are all fixedly connected to the slide plate 42. The lengths of the auxiliary roller 1 16, the auxiliary roller 2 18 and the auxiliary roller 3 23 are consistent, and the length of the auxiliary roller 4 25 is longer than that of the auxiliary roller 1 16, the auxiliary roller 2 18 and the auxiliary roller 3 23.

[0056] The cooperation of the auxiliary roller 1 16, the auxiliary roller 2 18, the auxiliary roller 3 23 and the auxiliary roller 4 25 makes the motor movement more convenient.

[0057] It should be noted that when the present invention is in use, the workbench 1 can be installed in a place where work is required to achieve the working operating conditions. In addition, in the initial state of the test bench, the end of the movable plate 13 away from the motor 14 is arranged toward the center of the baffle 9, the plug plate 32 is inserted into the inner side of the hollow plate 19 to be in a connected state, and the multi-stage electric telescopic rod 121 is in a retracted state, that is, the fixture assembly is in an expanded state, and the center of the baffle 9 and the connection position of the detector 2 match, that is, a coaxial arrangement;

[0058] When a small-sized motor needs to be tested, according to the size of the motor to be tested, the two multi-stage electric telescopic rods 27 are started to act on the two limit plates 3 24 to rotate and open to both sides and then stop, and then the motor to be tested is placed on the auxiliary roller 3 23, and then the multi-stage electric telescopic rod 27 is started to make the two limit plates 3 24 move closer to the motor until the auxiliary roller 4 25 fits the surface of the motor and stops. At this time, the multi-stage electric telescopic rod 3 28 is started to make the push plate 1 29 act on the motor to move in the direction of the rack 8 until it moves within the range of the auxiliary roller 2 18 of the limit plate 2 17 and stops;

[0059] The multi-stage electric telescopic rod 1 21 is started to act on the storage plate 22 to move upward. Since the plug plate 32 is connected to the hollow plate 19, when the storage plate 22 rises, the storage plate 22 will move synchronously with the limit plate 2 17. Due to the setting of the adjustment disk 20 and the slider 1 11, when the limit plate 2 17 moves upward, the other three limit plates 15 will move synchronously, that is, the clamp assembly is retracted at this time. When the clamp assembly clamps the motor, the storage plate 22 stops rising. At this time, the auxiliary rollers 1 16 and 2 18 are in contact with the motor. The surface, and the output shaft of the motor matches the center position of the baffle 9 at this time, and then the multi-stage electric telescopic rod three 28 is started, and the push plate one 29 is acted on to push the motor toward the baffle 9, until one end of the motor is limited by the baffle 9 and the motor stops moving, and then the motor two 40 is started to act on the screw rod 39 to rotate, so that the slide plate 42 moves toward the detector 2 with the correction structure 4 and the auxiliary support structure 5 until it moves to the predetermined position and stops, and then the motor output shaft and the detector 2 are manually connected by bolts, and then the motor and the accompanying test motor 3 are started to carry out the test work;

[0060] In addition, when the storage plate 22 moves upward, the storage plate 22 moves synchronously with one end of the connecting rod 37 through the bottom rod 38, so that the other end of the connecting rod 37 slides with the second slider 35 outside the slide bar 34, and the spring 36 supports the second slider 35. Conversely, when the storage plate 22 moves downward, the storage plate 22 acts on the second slider 35 to move outside the slide bar 34 through the connecting rod 37, and compresses the spring 36 at the same time.

[0061] When it is necessary to test the large-size motor, the electric push rod 30 is started to act on the push plate 2 31 to move the plug plate 32, and the plug plate 32 leaves the inner side of the hollow plate 19. At this time, the storage plate 22 is moved down by the multi-stage electric telescopic rod 1 21, and then the motor 14 is started to act on the movable plate 13 to rotate 180 degrees and then stop. At this time, the limit plate 15 and the limit plate 2 17 near one end of the motor 14 are toward the center of the baffle 9, and then the storage plate 22 is moved up to be flush with the limit plate 2 17 by the multi-stage electric telescopic rod 1 21 and then stopped. The plug plate 32 is inserted into the inner side of the corresponding hollow plate 19, so that the storage plate 22 and the limiting plate 17 are connected to work in linkage, and then the above operation is repeated, the storage assembly limits the motor, and the motor is pushed to the range of the auxiliary roller 18 by the thrust assembly and then stopped, and then the multi-stage electric telescopic rod 1 21 is moved up, so that the clamp assembly clamps the motor, and then one end of the motor is pushed to the baffle 9 to be limited, and then the motor is moved to the predetermined position by the moving structure 6, and then the motor output shaft and the detector 2 are manually connected by bolts, and then the motor and the accompanying test motor 3 are started to carry out the test work;

[0062] In addition, the detector 2 is a torque detector, and its working principle has been disclosed in the patent with publication number "CN105548880A", so it will not be described in detail.
