[0033] The embodiment of the present invention provides a magnetic pole winding joint installation and positioning tool, such as Figure 1 As shown, the pole winding joint installation and positioning tooling includes: a support plate 1, a positioning portion provided on the support plate 1, and two joint positioning holes 3 arranged parallel to each other on the support plate 1. The aperture and spacing of the two joint positioning holes 3 need to be determined according to the diameter and spacing of the two joints 7 of the pole winding 5, wherein the pole winding 5 is provided with joint connection holes corresponding to the two joints 7. During installation, the support plate 1 can define the relative position of the support plate 1 and the pole winding 5 through the positioning portion, and the two joint positioning holes 3 are used to respectively accommodate the two joints 7 of the pole winding 5. The structure after the tooling and the pole winding 5 are installed is as shown in FIG. Figure 8 The two joint positioning holes 3 ensure the spacing between the two joints 7 and the concentricity between the joints 7 and the corresponding joint connection holes on the pole winding 5. Once the relative positions of the joints 7 and the pole winding 5 are determined, the joints 7 can be welded, and finally the pole winding 5 can be cast.

[0034] In some embodiments, the positioning portion includes at least two positioning pins 2 provided on the support plate, each positioning pin 2 being used to correspond to each mounting hole 6 provided on the pole winding. For example, the support plate 1 is provided with two positioning pins 2 provided in parallel with each other, and the diameter and spacing of the two positioning pins 2 need to be determined according to the diameter and spacing of the two mounting holes 6 of the pole winding 5; during installation, the two positioning pins 2 are used to be provided in the two mounting holes 6 of the pole winding 5, wherein one side of the support plate 1 contacts the one side of the pole winding 5. Combined with the positioning function of the two positioning pins 2, the relative position of the support plate 1 and the pole winding 5 can be defined. It should be noted that this embodiment is only described with two positioning pins 2 as an example, and more positioning pins 2 can be provided as needed to improve the positioning stability of the support plate 1. In addition, providing positioning pins 2 on the support plate 1 is only an optional embodiment. The positioning pins 2 can also be connected to the mounting holes 6 of the pole winding 5, and positioning holes that cooperate with the positioning pins 2 are provided on the support plate 1. In this case, the positioning holes serve as the positioning portion.

[0035] In some embodiments, as Figure 1 、 Figure 5 and Figure 8 As shown, the support plate 1 is further provided with a fastening hole 4, and the pole winding 5 has a connecting hole 8 corresponding to the fastening hole 4. The fastening hole 4 and the axis of the positioning pin 2 are parallel to each other. During installation, the fastening hole 4 corresponds to the connecting hole 8 of the pole winding 5, and the fastener 9 is inserted into the fastening hole 4 and the connecting hole 8 to achieve the fixation of the pole winding 5 and the support plate 1. The fastening hole 4 and the connecting hole 8 can be threaded holes, and the fastener 9 can be a bolt. The fastener 9 can improve the stability of the pole winding 5 and the support plate 1 after installation, thereby improving the installation accuracy of the joint 7.

[0036] In some embodiments, as Figure 1 and Figure 2 As shown, the support plate 1 is an L-shaped support plate 1, which includes a vertical plate and a horizontal plate located at the upper end of the vertical plate. The horizontal plate extends toward the back of the vertical plate, and two positioning pins 2 are arranged in the front of the vertical plate. The extension direction of the horizontal plate is opposite to the extension direction of the positioning pins 2. Two joint positioning holes 3 are provided on the horizontal plate, and the openings are facing the front of the horizontal plate, that is, the joint positioning holes 3 and the positioning pins 2 are both facing the front of the support plate 1. The length of the joint positioning hole 3 in the front-to-back direction is greater than the thickness of the vertical plate, which is equivalent to reducing the thickness of the vertical plate, which can effectively save material costs. The two positioning pins 2 are distributed in the up and down directions, and the two joint positioning holes 3 are distributed in the horizontal direction. The positioning pins 2 can ensure the accuracy of the upper and lower positions of the joint 7, and the joint positioning holes 3 can ensure the accuracy of the left and right positions of the joint 7.

[0037] In some embodiments, as Figure 1 and Figure 2As shown, the two joint positioning holes 3 are both blind holes. During installation, when the end face of the joint 7 contacts the end face inside the blind hole, the axial position of the joint 7 can be limited. Therefore, the position of the joint 7 in the front-to-back direction can be limited by the blind hole, thereby further improving the position accuracy of the joint 7 during installation.

[0038] In some embodiments, as Figure 1 and Figure 3 As shown, the two joint positioning holes 3 are both U-shaped slots with the slots facing upwards. Since the main function of the joint positioning holes 3 is to limit the position of the joint 7 in the left and right directions, the limiting function of the joint 7 in the upper and lower positions is achieved by relying on the positioning pin 2. Therefore, by designing the joint positioning holes 3 as U-shaped slots, it is possible to facilitate the placement of the joint 7 in the joint positioning holes 3, thereby improving the convenience of installing the joint 7.

[0039] In some embodiments, as Figure 1 As shown, the fastening hole 4 is provided on the vertical plate and is located above the uppermost positioning pin 2 and below the joint positioning hole 3, wherein the distance between the fastening hole 4 and the uppermost positioning pin 2 is the same as the distance between the connecting hole 8 on the pole winding 5 and the uppermost mounting hole 6.

[0040] In some embodiments, the positioning pin 2 is detachably connected to the vertical plate. By designing the positioning pin 2 to be detachably connected, that is, the positioning pin 2 and the vertical plate are split structures and can be manufactured separately, compared with directly forming the positioning pin 2 on the vertical plate, the manufacturing convenience can be effectively improved. In addition, it is also convenient to replace positioning pins 2 of different diameters to improve its adaptability to different installation requirements.

[0041] In some embodiments, in order to improve the adaptability to different pole windings 5, for example, there are differences in the spacing between the mounting holes 6 of the pole windings 5, at least three pin holes distributed in the vertical direction can be set on the vertical plate, and two positioning pins 2 are selectively connected to two of the pin holes. For example, when the spacing between the mounting holes 6 of the pole windings 5 is large, two pin holes that are farther apart can be selected to connect the positioning pins 2. When the spacing between the mounting holes 6 of the pole windings 5 is small, two pin holes that are closer to each other can be selected to connect the positioning pins 2. By setting a plurality of pin holes for connecting the positioning pins 2 on the vertical plate, it is possible to match positioning pins 2 with different spacings on the same support plate 1. There is no need to design different tooling for pole windings 5 with different spacings between mounting holes 6, so the cost can be significantly reduced.

[0042] In some embodiments, the L-shaped support plate 1 is an integrally formed structure. By manufacturing the L-shaped support plate 1 as a whole, the manufacturing convenience can be effectively improved and the structure strength can be higher.

[0043] In some embodiments, the horizontal plate and the vertical plate are detachably connected. For example, a snap-fit protrusion extending in the left-right direction can be provided at the bottom of the horizontal plate, and a snap-fit groove extending in the left-right direction can be provided at the upper end of the vertical plate. The snap-fit protrusion of the horizontal plate can be pushed into and snapped into the snap-fit groove from one end of the snap-fit groove, wherein the snap-fit protrusion can be optionally a dovetail protrusion or a T-shaped protrusion, etc., and the snap-fit groove can be optionally a dovetail groove or a T-shaped groove, etc.

[0044] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0045] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the core idea of the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified in several ways, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
