[0028] Furthermore, the clamping structure includes a clamping groove and a clamping claw. The lower part of the clamping claw 5 is arranged in the clamping groove, and the clamping claw 5 and the clamping groove form a sliding pair.

[0029] Furthermore, the supporting structure includes a supporting groove and a sliding block. The supporting groove is arranged on the upper surface of the pallet seat 2. The sliding block is arranged in the supporting groove. The sliding block and the supporting groove constitute a sliding pair. A supporting rod 4 is arranged on the top surface of any sliding block. The axial direction of the supporting rod 4 is perpendicular to the upper surface of the pallet seat 2.

[0030] Furthermore, a support 9 is provided on the upper side of the main lifting rod 8 , the bottom of the support 9 and the top of the main lifting rod 8 form a rotating pair, and the support plate 10 is provided on the support 9 .

[0031] Furthermore, it also includes a display device 15, which is arranged on the base 1. The display device 15 includes a controller and a display screen.

[0035] Furthermore, the cross section of the support groove is trapezoidal, dovetail-shaped or inverted T-shaped, and the cross section shape of the slider matches the cross section shape of the support groove.

[0036] Specifically, the above-mentioned sliding pair and rotating pair structures are all mature mechanical connection methods in the prior art, and will not be described in detail here.

[0037] Among them, the clamping claw 5 forms a sliding pair with the upper side of the tray seat 2 along the radial direction of the central axis 3, and the clamping claw 5 can be driven to move radially along the central axis 3 by a driving device (such as a motor, etc.) or a driving structure (such as a gear transmission mechanism, etc.), or a three-jaw chuck mechanism can be used.

The sensor 14 can adopt the technology disclosed in patent documents CN110114636B (displacement sensor) and CN113494880B (displacement sensor).

[0043] The working process of this embodiment:

[0044] Installation step 1: Place the non-outgoing end side of the stator core 20 on three support rods 4, and adjust the radial distance between the support rods 4 and the central axis 3 to facilitate the installation of stator cores 20 with different outer diameters. At the same time, support the stator core 20 through the support rods 4 to prevent the non-outgoing end winding from being damaged due to the weight of the stator core 20.

[0045] Installation step 2: adjust the clamping claw 5 so that the clamping claw 5 is closely fitted to the outer circumference of the stator core 20 to fix the stator component and ensure that it does not move;

[0046] Installation step three: install the three-phase copper bar 30 on the positioning seat 13, with the connection end of the three-phase copper bar 30 facing the stator core 20;

[0047] Adjustment step 1: by rotating the tray seat 2 on the base 1 at the same time, ensure that the side of the stator core 20 outlet end and the positioning seat 13 (three-phase copper bar 30) are within a suitable angle range;

[0048] Adjustment step 2, adjusting the relative position of the base 7 in the first slide slot 6, and roughly determining the relative position between the outlet end of the stator core 20 and the positioning seat 13 (three-phase copper busbar 30);

[0049] Adjustment step three, then by adjusting the length of the main lifting rod 8, the relative height of the positioning seat 13 (three-phase copper busbar 30) is roughly adjusted;

[0050] Adjustment step 4: by rotating the support 9, the positioning seat 13 (three-phase copper bar 30) and the stator core 20 outlet end are at a suitable angle;

[0051] Adjustment step five, then by adjusting the length of the auxiliary lifting rod 12 and the relative position of the auxiliary lifting rod 12 on the second slide slot 11, so as to achieve the positioning seat 13 (three-phase copper busbar 30) closer to the ideal position;

[0052] Adjustment step six, finally by adjusting the relative position of the positioning seat 13 (three-phase copper bar 30) and the top of the auxiliary lifting rod 12, such as Figure 6 As shown, the three positioning seats 13 (three-phase copper bars 30) are made to coincide with the expected positions of the outlet terminals of the stator core 20, thereby finally realizing the positioning of the three-phase outlet interface of the flat wire permanent magnet synchronous motor.

[0053] In the production process of a motor solution, it is only necessary to adjust the stator positioning mechanism and the three-phase output line positioning mechanism for the first time so that their positions conform to the solution positioning. After that, it is only necessary to place the corresponding stator and three-phase output line at the corresponding positions to carry out the subsequent installation process.
