[0033] Refer to Figure 1 , Figure 2 , in some embodiments, the support plate 100 is a split structure. In this embodiment, the support plate 100 includes three sector-shaped unit members 200. Each sector-shaped unit member 200 is provided with a first notch 230, a first supporting portion unit 210 and a second supporting portion unit 220. The three sector-shaped unit members 200 are spliced into the support plate 100. The first notch 230 is arc-shaped. The first notches 230 on the three sector-shaped unit members 200 are combined to form a circular first through hole 110. The first supporting portion units 210 on the three sector-shaped unit members 200 are combined to form the first supporting portion 130. The second supporting portion units 220 on the three sector-shaped unit members 200 are combined to form the second supporting portion 140. By splitting the support plate 100 into three sector-shaped unit members 200, it is convenient to install and disassemble the positioning tool 10 on site and is convenient for the installer to operate.

[0034] It can be understood that the sector-shaped unit member 200 can also be set to two, four or more according to specific situations, which is not limited herein.

[0035] Refer to Figure 1 , Figure 2, in some embodiments, along the circumferential direction of the first notch 230, the sector unit member 200 is provided with a first reinforcing rib 240. The first reinforcing rib 240 extends along the axial direction of the first through hole 110. The side wall of the first notch 230 is in smooth transition with the side portion of the first reinforcing rib 240. When three sector unit members 200 are spliced into the support plate 100, the first notches 230 are combined to form the first through hole 110. Moreover, the first reinforcing ribs 240 of the three sector unit members 200 enclose together, and the side wall of the first through hole 110 extends along its axial direction, increasing the length of the first through hole 110, and further increasing the side area of the first through hole 110. Thus, not only the contact area between the central shaft 500 and the side wall of the first through hole 110 is increased, enhancing the stability of the central shaft 500 in the first through hole 110, but also, due to the setting of the first reinforcing rib 240, the strength of the support plate 100 at the first through hole 110 is improved.

[0036] Refer to Figure 1 、 Figure 2 , in some embodiments, the sector unit member 200 is provided with a second reinforcing rib 250. The second reinforcing rib 250 extends along the radial direction of the first through hole 110. By providing the second reinforcing rib 250, the strength of the sector unit member 200 along its radial direction can be improved, and further the strength of the support plate 100 can be improved.

[0037] Refer to Figure 1 、 Figure 2 , in some embodiments, the second reinforcing rib 250 is provided at the edges on both sides of the sector unit member 200. An assembly hole 251 is provided on the second reinforcing rib 250. When multiple sector unit members 200 are spliced into the support plate 100, the adjacent two second reinforcing ribs 250 on adjacent two sector unit members 200 abut against each other, and the assembly holes 251 on the two second reinforcing ribs 250 correspond. By means of fasteners such as bolts passing through the assembly holes 251 in the two second reinforcing ribs 250, the adjacent two sector unit members 200 can be fixed together, thereby splicing multiple sector unit members 200 into the support plate 100, and finally forming the positioning tooling 10 of the present application. With the structural setting of this embodiment, there is no need to additionally provide a connecting portion, reducing the mold opening difficulty and the material consumption.

[0038] Refer to Figure 1 、 Figure 2 , in some embodiments, the sector unit member 200 is provided with a third reinforcing rib 260. The third reinforcing rib 260 is arc-shaped, and both ends of the third reinforcing rib 260 extend to the edges on both sides of the sector unit member 200.

[0039] In some embodiments, the fan-shaped unit member 200 is provided with a first reinforcing rib 240, a second reinforcing rib 250, and a third reinforcing rib 260. The first reinforcing rib 240 extends along the periphery of the first notch 230. The second reinforcing rib 250 is disposed at the edges on both sides of the fan-shaped unit member 200. The third reinforcing rib 260 is arranged in an arc shape, and both ends of the third reinforcing rib 260 extend to the edges on both sides of the fan-shaped unit member 200. Moreover, both ends of the first reinforcing rib 240 are connected to one end of the second reinforcing rib 250, and both ends of the third reinforcing rib 260 are connected to the other end of the second reinforcing rib 250. The first reinforcing rib 240, the second reinforcing rib 250, and the third reinforcing rib 260 form a closed frame structure, thereby improving the strength of the fan-shaped unit member 200, and further improving the strength of the positioning tooling 10, and avoiding deformation of the positioning tooling 10 during use.

[0040] Referring to Figure 1 、 Figure 2 , in some embodiments, second notches 270 are correspondingly provided at the edges on both sides of the fan-shaped unit member 200. When multiple fan-shaped unit members 200 are spliced into the support plate 100, the corresponding second notches 270 on two adjacent fan-shaped unit members 200 are spliced into a second through hole 120. Thus, when disassembling the positioning tooling 10, the connecting bolts between the fan-shaped unit members 200 are removed, and the connecting bolts between the positioning tooling 10 and the bus bar 300 are removed, and then each fan-shaped unit member 200 can be taken out, which is convenient and fast.

[0041] Referring to Figure 1 、 Figure 2 , in some embodiments, an avoidance notch 160 is formed between multiple support portions 150, and the avoidance notch 160 is correspondingly arranged with the second through hole 120. The avoidance notch is used to avoid the connection end on the conductive ring 400, so as to facilitate the connection between the conductive ring 400 and the connection end on the insulating support 600.

[0042] Referring to Figure 1 、 Figure 2 , in some embodiments, the first supporting portion 130 is provided with multiple connection holes 170, and the multiple connection holes 170 are arranged along the circumferential direction of the support plate 100. The bus bar 300 can be accurately positioned by fasteners such as bolts passing through the connection holes 170.

[0043] Referring to Figure 3, when using the positioning tooling 10 of the present utility model to assemble and position the busbar 300 and the conductive ring 400, first assemble each sector unit member 200. The insulating support member 600 of the rotary power transmission device is inserted into the corresponding second through hole 120 of the support plate 100, and the central shaft 500 of the rotary power transmission device is inserted into the first through hole 110. Then, fasteners are used to fixedly connect each sector unit member 200 together. Next, place the busbar 300 on the first supporting portion 130 of the support plate 100, place the conductive ring 400 on the second supporting portion 140 of the support plate 100, then connect the conductive ring 400 with the insulating support member 600, and connect the busbar 300 with another insulating support member. Adjust the relative positions of the busbar 300 and the conductive ring 400, and adjust the concentricity between the busbar 300 and the conductive ring 400. Tighten each fastener to fix the relative positions between the busbar 300 and the conductive ring 400. Before the rotary power transmission device operates, simply disassemble the positioning tooling 10. Thus, it can be seen that by using the positioning tooling 10 of the present utility model, the concentricity of the busbar and the conductive ring 400 can be improved, the operation reliability of the rotary power transmission device can be enhanced, and the installation workload can be reduced and the assembly difficulty can be lowered.
