Description

Technical Field

[0001] This invention relates to the field of motor technology, and in particular to a stator winding wiring copper busbar positioning device. Background Technology

[0002] The stator winding connecting copper busbars are arranged at a certain angle on the phase rings of the winding end support. There is a certain angle between the copper busbars, and they are arranged on different phase rings. The other end of the connecting copper busbar is connected to the clamp base on the junction box.

[0003] Existing technologies use marking lines or simple tooling to align the angles. However, these methods result in significant angular deviations, leading to angle misalignment. Furthermore, these methods cannot effectively secure the copper busbars during welding, causing deformation after welding and misalignment between the busbars. Both of these factors exacerbate the positional and angular deviations of the copper busbars, ultimately causing misalignment during installation with the junction box's clamp base. Since the surface of the copper busbars needs to be coated with an insulating layer after welding and then impregnated and cured along with the stator windings, misalignment with the clamp base due to positional and angular deviations will prevent the correction of the copper busbar position. Therefore, there is an urgent need for a stator winding copper busbar positioning device to solve these problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the existing technology in which the copper busbar of the stator winding is prone to deformation and positional displacement during the welding process, and to provide a positioning device for the copper busbar of the stator winding.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A stator winding busbar positioning device includes a base, a movable component, and a positioning unit. The base is fixed to the stator retaining ring of the stator winding. One side of the base mates with the outer circumferential surface of the stator retaining ring. A movable track is provided on the base. The movable track is arc-shaped, and the center of the arc of the movable track coincides with the center of the stator retaining ring. The movable component is disposed on the base and can move along the movable track. The positioning unit is disposed on the movable component and is used to align the stator winding busbar with the axial direction of the stator retaining ring.

[0007] In this solution, the above-mentioned structural form is adopted, and the moving component can slide along the moving track on the base, which facilitates the correction of the wiring copper busbar at different angle positions. The positioning unit can fix the position of the wiring copper busbar during welding, effectively preventing the wiring copper busbar from shifting position.

[0008] Preferably, the positioning unit includes a first structural arm and a second structural arm, which are arranged parallel to each other in the vertical direction, and the first structural arm and the second structural arm are provided with corresponding positioning holes.

[0009] Preferably, the positioning unit further includes a positioning rod, which is detachably inserted into the positioning hole and is used to pass through a hole on the wiring busbar.

[0010] In this solution, the above-mentioned structural form is adopted. The first structural arm, the second structural arm, the positioning hole, and the positioning rod of the positioning unit can limit the radial and circumferential movement of the wiring copper busbar, avoiding positional deviation caused by welding deformation.

[0011] Preferably, one end of the positioning rod is provided with a boss, the diameter of which is larger than the diameter of the positioning hole.

[0012] In this solution, the above-mentioned structural form ensures that the positioning rod will not fall out when inserted into the positioning hole.

[0013] Preferably, the base has a scale area along the moving track, the scale area has a rotation angle, and the scale area is located on the side of the moving track near the stator pressure ring.

[0014] In this solution, the above-mentioned structural form is adopted, and the scale area provided can improve the practicality and accuracy of the device, enabling the device to correct the wiring copper busbars at different angles.

[0015] Preferably, the movable member is provided with an indicator component, which is aligned with the positioning hole in the radial direction of the stator pressure ring.

[0016] In this solution, the above-mentioned structural form is adopted, and the indicator component can improve the accuracy of the positioning hole and make the angle position of the wiring copper busbar more accurate.

[0017] Preferably, the lower end of the indicating component points to the scale line of the scale area.

[0018] In this solution, the above-described structural form allows for more precise adjustment of the device to the required angle. 。

[0019] Preferably, the base is provided with a height equalization component along the moving track, and the two ends of the height equalization component are provided with height equalization screw holes. The height equalization screw holes are detachably connected to the round holes of the support on the stator pressure ring by bolts.

[0020] In this solution, the above-mentioned structural form is adopted. The equal-height screw holes on the equal-height component are aligned with the circular holes on the support on the stator pressure ring, and bolts are used to connect them, so that the left and right sides of the base are at the same height, ensuring flatness.

[0021] Preferably, the bottom of the movable component is provided with a guide component, and the movable component is installed in the movable track through the guide component.

[0022] In this solution, the above-mentioned structural form is adopted, allowing the moving component to slide freely along the moving track.

[0023] The positive and progressive effects of this invention are as follows: the stator winding copper busbar positioning device includes a base, a moving component, and a positioning unit. The moving component can slide along the moving track on the base, which facilitates the correction of the copper busbars at different angles. The positioning unit can fix the position of the copper busbars during welding, effectively preventing the copper busbars from shifting position, improving the accuracy of installation, avoiding the scrapping of some parts due to large positional misalignment, and saving production costs.

[0045] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0046] like Figure 1 and Figure 2 As shown, this embodiment provides a stator winding wiring busbar positioning device 100, which includes a base 10, a moving member 20, and a positioning unit 30. The base 10 is fixed to the stator pressure ring 40 of the stator winding. One side of the base 10 matches the shape of the outer peripheral surface of the stator pressure ring 40. Here, the shape matches the curvature of the outer peripheral surface of the stator pressure ring 40 and the curvature of one side of the base 10, so that the side of the base 10 facing the stator pressure ring 40 can fit against the outer peripheral surface of the stator pressure ring 40. A moving track 11 is provided on the base 10. The moving track 11 is arc-shaped, and the center of the arc of the moving track 11 coincides with the center of the stator pressure ring 40. The moving member 20 is provided on the base 10 and can move along the moving track 11. The positioning unit 30 is provided on the moving member 20 and is used to align the wiring busbar 60 of the stator winding in the axial direction of the stator pressure ring 40.

[0047] Specifically, in this embodiment, the movable component 20 can slide along the movable track 11 on the base 10, which facilitates the correction of copper busbars at different angles. The positioning unit 30 can fix the position of the wiring copper busbar 60 during welding, effectively avoiding the displacement of the copper busbar position. Compared with the prior art of aligning the angle of the wiring copper busbar 60 by scribing or simple tooling, the stator winding wiring copper busbar positioning device 100 provided in this embodiment solves the problem of position and angle deviation of the wiring copper busbar 60 during welding, improves production efficiency and installation accuracy, and can also avoid the scrapping of some parts due to large position misalignment, thus saving production costs.

[0048] like Figure 1As shown, the positioning unit 30 includes a first structural arm 31 and a second structural arm 32, which are arranged parallel to each other in the vertical direction. The first structural arm 31 and the second structural arm 32 are provided with corresponding positioning holes. The positioning unit 30 also includes a positioning rod 33, which is detachably inserted into the positioning hole. The positioning rod 33 is used to pass through the through hole 61 on the copper busbar 60, and one end of the positioning rod 33 is provided with a boss 331. The diameter of the boss 331 is larger than the diameter of the positioning hole, which can ensure that the positioning rod 33 will not fall out when inserted into the positioning hole. The positioning unit 30 can fix the position of the copper busbar 60 during welding by using the positioning hole and the positioning rod 33. The positioning rod 33 passes through both the positioning hole and the through hole 61 on the copper busbar 60, which can limit the radial and circumferential movement of the copper busbar 60, effectively preventing the copper busbar 60 from shifting position.

[0049] like Figure 1 As shown, a scale area 12 is provided on the base 10 along the moving track 11. The scale area 12 has rotation angles. The scale area 12 is located on the side of the moving track 11 near the stator pressure ring 40. In this embodiment, the scale area 12 on the base 10 can improve the accuracy of the device and facilitate the adjustment of the device to the required angle. When using the device, the 0° scale line on the scale area 12 needs to be aligned with the 180° pressure ring scale line of the stator winding. Then, the moving component 20 is adjusted to the welding position according to the actual angle needs each time. The specific degree range of the scale area 12 is also set according to the actual angle needs, such as 0~90°, 0~120°, 0~150°, etc. In other alternative embodiments, the scale area 12 on the base 10 can also be set as a separate scale plate, and the base 10 and the scale plate can be used together.

[0050] In this embodiment, a height equalization component 13 is also provided on the base 10 along the moving track 11. The two ends of the height equalization component 13 are provided with height equalization screw holes. The height equalization screw holes are detachably connected to the round holes of the support 50 on the stator pressure ring 40 by bolts. The height equalization screw holes on the height equalization component 13 are aligned with the round holes of the support 50 on the stator pressure ring 40. After bolt connection, the left and right sides of the base 10 are at the same height, ensuring the flatness of the device.

[0051] like Figure 1 As shown, the moving component 20 is provided with an indicator component 22. The indicator component 22 is aligned with the positioning hole in the radial direction of the stator pressure ring 40. The lower end of the indicator component 22 points to the scale line of the scale area 12. By setting the indicator component 22, the device can be accurately moved to the required place, thereby improving the accuracy of the device.

[0052] like Figure 2As shown, the bottom of the movable component 20 is provided with a guide component 21. The movable component 20 is installed in the movable track 11 through the guide component 21, so that the movable component 20 can slide freely in the movable track 11. In this embodiment, the bottom of the movable component 20 is provided with two guide components 21. In other alternative embodiments, the bottom of the movable component 20 may also have one or more guide components 21.

[0053] When using the stator winding copper busbar positioning device 100 provided by the present invention, the copper busbars 60 are placed sequentially from bottom to top onto the corresponding phase rings 70. The stator winding copper busbar positioning device 100 is moved so that its base 10 is in contact with the stator pressure ring 40 and aligned with the scale. The height-equalizing screw hole of the height-equalizing component 13 is aligned with the round hole on the support 50 of the stator pressure ring 40. The base 10 is fixed with bolts and leveled. The moving component 20 is adjusted to a suitable position so that the positioning hole is aligned with the through hole 61 on the copper busbar 60. The positioning rod 33 is inserted into both the positioning hole and the through hole 61 on the copper busbar 60. The copper busbar 60 is then welded to the corresponding phase ring 70. After welding, the positioning rod 33 is removed. According to the required angle, the moving component 20 is adjusted to the next welding position by relying on the scale area 12 and the indicating component 22. The above steps are repeated, and the angle is adjusted sequentially for welding.

[0054] The stator winding busbar positioning device 100 provided by this invention can be used in the field of motor technology such as generators and motors. This positioning device solves the problem of assembly angle deviation of the busbar 60, and avoids misalignment with the junction box caused by angle deviation between the busbars. The scale area 12 and the moving component 20 set on the base 10 enable the device to correct the busbar 60 at different angles, improving the accuracy of the angle position. Through the positioning rod 33 and the positioning hole, the position of the busbar 60 can be positioned during welding and the busbar 60 can be limited, effectively preventing the position of the busbar 60 from shifting.
