[0037] When it is necessary to take out the motor A, just hold the motor A and then pull it outwards so that the first bearing B1 on the motor A disengages from the groove 41. During this period, the shaft of the motor A synchronously displaces along the groove cavity 401, and finally the motor A is disassembled from the clamping member 4.

[0038] The lower pressing plate 3 is placed below the workbench 11, and the output end of the second hydraulic cylinder 62 is connected to the lower pressing plate 3. Six second workstations for placing the second bearing B2 are provided on the end face of the lower pressing plate 3.

[0039] A ring body 5 is provided on this second workstation. A central hole for placing the second bearing B2 is provided on the ring body 5, and a through hole 30 communicating with the central hole is provided on the lower pressing plate 3 so that the shaft of the other end of the motor A can extend out.

[0040] The lower pressing plate 3 is provided with a hole position for the lower guide rod 22 to move. A second spring 32 is sleeved on the lower guide rod 22, and both ends of the second spring 32 are respectively connected to the lower pressing plate 3 and the workstation table.

[0041] A detection component is further provided on the workbench 11. The detection component includes a base 7 and several sensors. The base 7 is slidably connected to the workbench 11, and a workstation for receiving the motor A is provided on the base 7.

A step portion 72 for receiving the second bearing B2 is provided on the end face of the base 7 corresponding to the position of the limiting plate 71. An opening communicating with the step portion is provided on the outer end face of the base 7 so that the shaft of the motor A and the second bearing B2 can enter and exit below the limiting plate 71.

[0043] The sensor is placed at the end of the moving path of the base 7.

[0044] A stroke cylinder is provided on the workbench 11. Two slide rails 70 are provided on the workbench 11. A slider slidably connected to the slide rails is fixed at the bottom of the base 7. The output end of the stroke cylinder 63 is connected to one side of the base 7 so as to push the base 7 to receive the motor A and then send it to the sensor for detection.

[0045] The output end of the first hydraulic cylinder 61 is further connected with a support. A first sensor 81 is placed on the support. The sensing end of the first sensor 81 on the support corresponds to downward detection of the first bearing B1.

[0049] Working principle: six bearings B1 are placed from the U-shaped groove 402 of the clamp 4 and supported by the clamp 4, six bearings B2 are placed in the center hole of the ring body 5, and six motors A to be installed are placed in the pressure-bearing station holes 10 of the workbench 11.

[0050] The first hydraulic cylinder 61 drives the upper pressure plate 2 to squeeze downward, so that the bearing 1 B1 squeezes and fixes the upper shaft of the motor A, and then the second hydraulic cylinder drives the lower pressure plate 3 to squeeze upward, so that the bearing 2 B2 squeezes and fixes the lower shaft of the motor A.

[0051] When bearing 1 B1 and bearing 2 B2 are installed to motor A, the stroke cylinder pushes the base 7 to move forward; the first hydraulic cylinder 61 drives the upper pressure plate 2 to lift, so that motor A is disengaged from the pressure-bearing station hole 10, and the base 7 will receive the motor A hung on the clamp 4 during displacement. During the movement of the base 7, the motor A will fall into its station, and the motors A on its active path will conflict with each other and be placed in the station, and finally to between sensor 1 81 and sensor 2 82. The position of the bearing is detected by sensor 1 81 and sensor 2 82 to determine whether the installation is qualified. This qualification is to detect whether the position of bearing 1 B1 and bearing 2 B2 squeezed and installed on the shaft of motor A is in place. The end faces of the six bearings 1 B1 and the six bearings 2 B2 should be in the same horizontal plane. The end face heights of bearings 1 B1 and bearing 2 B2 are detected by sensor 1 81 and sensor 2 82 to determine whether they are qualified.
