[0006] In this embodiment, the driving mechanism includes a motor, a screw and multiple sealed bearings. The sealed bearings are installed in the openings at both ends of the through hole. The motor is installed on the end face of the center column. The two ends of the screw are threadedly connected to the adjusting ring and then installed in the inner ring of the sealed bearing. The rotating shaft of the motor is fixedly connected to one end of the screw.

[0007] In this embodiment, a U-shaped plate is installed on the other end surface of the center column, and a cylinder that drives the center column and the motor stator to be inserted into the motor housing is installed on the outer surface of the U-shaped plate, and a fixing seat is installed outside the cylinder.

[0008] In this embodiment, the diameter of the central column matches the inner diameter of the motor stator.

[0009] In this embodiment, a limiting groove is axially arranged on the bottom surface of the through hole, and the outer ring surface of the adjustment ring protrudes opposite to the limiting groove to form a limiting portion, and the limiting portion is slidably arranged in the limiting groove.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an automatic positioning and assembling device for a stator housing of the utility model comprises a motor 13 stator 1 and a center column 2, wherein the center column 2 is inserted into the interior of the motor 13 stator 1, and a plurality of positioning grooves 3 are axially arranged on the outer ring surface of the center column 2, and both ends of the center column 2 are sleeved with limit rings 4, and the inner side surfaces of the limit rings 4 are arranged to abut against the two end surfaces of the motor 13 stator 1, and a plurality of pressure plates 5 are installed on the inner ring surface of the limit ring 4, and the other ends of the pressure plates 5 are slidably arranged in the positioning grooves 3, and a through hole is axially arranged at the center of the center column 2, and both ends of the center column 2 are provided with rectangular grooves 14 connected to the through hole, and a plurality of adjusting rings 8 are arranged in the through hole, and a plurality of slots 17 are arranged on the outer ring surface of the adjusting ring 8, and plug plates 7 are inserted into the slots 17, and the other ends of the plug plates 7 are expanded to form extrusion parts 6, and the extrusion parts 6 pass through the rectangular grooves 14 and abut against the outer side surfaces of the pressure plates 5, and a driving mechanism for driving the adjusting rings 8 to move inward is installed on the center column 2.

[0021] In this embodiment, the driving mechanism includes a motor 13, a screw 15 and a plurality of sealed bearings 9. The sealed bearings 9 are installed in the openings at both ends of the through hole. The motor 13 is installed on the end face of the center column 2. The two ends of the screw 15 are threadedly connected to the adjusting ring 8 and then installed in the inner ring of the sealed bearing 9. The rotating shaft of the motor 13 is fixedly connected to one end of the screw 15; wherein, the screw uses the middle as a dividing line, and the screw threads of the screw on both sides of the dividing line are arranged oppositely, so that the adjusting ring can be driven to move inward or away synchronously.

[0022] In this embodiment, a U-shaped plate 10 is installed on the other end face of the center column 2, and a cylinder 12 is installed on the outer side face of the U-shaped plate 10 to drive the center column 2 and the stator 1 of the motor 13 to be inserted into the motor 13 housing, and a fixed seat 11 is installed on the outside of the cylinder 12.

[0023] In this embodiment, the diameter of the center column 2 matches the inner diameter of the stator 1 of the motor 13, so that the motor stator can be centrally positioned, avoiding swinging and increasing stability. The positioning groove reduces the contact area between the center column and the motor stator, facilitating the removal and insertion of the center column and reducing friction.

[0024] In this embodiment, a limiting groove 16 is axially provided on the bottom surface of the through hole, and the outer ring surface of the adjusting ring 8 protrudes opposite the limiting groove 16 to form a limiting portion, and the limiting portion is slidably arranged in the limiting groove 16. The adjusting ring can be positioned through the limiting portion and the limiting groove so that the adjusting ring can only move axially along the limiting groove.

[0025] During installation, first pull out the plug plate on one side. After the plug plate and the extrusion part are blocked, the limit ring can be taken out along the positioning groove. After the positioning plate is blocked, the motor stator can be directly sleeved on the center column to center the motor stator. Then, the limit ring is re-sleeved. The positioning plate on the limit ring can be inserted into the positioning groove, and the extrusion part can be inserted into the slot through the plug plate.

[0026] After the above is completed, the motor can be started, and the starting of the motor drives the screw rod. The rotation of the screw rod can drive the adjusting ring to move inward along the limiting groove. The movement of the adjusting ring drives the plug plate and the extrusion part. The extrusion part moving inward can push the positioning plate, so that the positioning plate moves along the positioning groove. The movement of the positioning plate synchronously drives the limiting ring. The limiting ring moving inward can clamp the motor stator to avoid loosening, and also synchronously completes the clamping of the iron core to avoid loosening.

[0027] The motor housing can be clamped and fixed by any clamping device, and after being aligned with the motor stator, the cylinder can be started to extend the piston rod of the cylinder, and the motor stator can be automatically pressed into the motor housing through the extended piston rod, which increases the stability and accuracy of the installation;

[0028] After the installation is completed, the motor can be started in reverse to disengage the pressure-bearing part from the positioning plate. At this time, the plug plate can be pulled out. After the plug plate is no longer blocked, the limit ring on one side can be removed from the center column. After the limit ring is no longer blocked, the center column can be directly pulled out of the motor stator.

[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
