Description

Technical Field

[0001] This utility model relates to the field of marine generator assembly technology, specifically a positioning fixture for parallel-connected copper busbars, used for positioning parallel-connected copper busbars during the assembly process of marine generators. Background Technology

[0002] During the assembly process of marine generators PMM1000 and PMM1500 series products, such as Figure 9 The connecting ring 1 is fixedly connected to the end plate 16 of the PMM1000 and PMM1500 fuselage via an insulating support. The specific structure of the connecting ring 1 is as follows: Figure 1 As shown, the parallel ring 1 includes a left semicircular parallel ring 2 and a right semicircular parallel ring 3. Both the left semicircular parallel ring 2 and the right semicircular parallel ring 3 are composed of multiple semicircular rings arranged concentrically. Each semicircular ring has a parallel ring connecting copper busbar (hereinafter referred to as connecting copper busbar 4) welded to both ends. The parallel ring 1 is fixedly connected to the end plate 16 of the machine body through an insulating support. Due to the tension of the parallel ring 1 itself, the position of the connecting copper busbar 4 welded on the parallel ring 1 is difficult to accurately position, resulting in the spacing between adjacent connecting copper busbars 4 not meeting the requirements of the drawing. Workers face insufficient operating space when subsequently wrapping the parallel ring 1 and connecting copper busbar 4 with an insulating layer. Furthermore, after installing the end cover on the end plate 16 of the machine body, when workers tie the cables on the connecting copper busbar 4 to the support rods on the end cover, the discrepancy between the spacing between adjacent connecting copper busbars 4 and the corresponding support rods on the end cover makes it difficult to tie the cables to the support rods on the end cover. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a positioning fixture for parallel and interlocking copper busbars, which addresses the shortcomings of the prior art. This positioning fixture can accurately position the copper busbars, and after positioning, the insulation layer wrapping process of the parallel and interlocking copper busbars and the copper busbars can be carried out. It solves the problem that the position of the copper busbars is difficult to accurately position in the prior art, resulting in insufficient operating space for workers in the subsequent parallel and interlocking copper busbars and copper busbar insulation layer wrapping process; it also solves the problem that the relative position of the cable on each copper busbar is deviated from the corresponding support rod on the end cover due to the non-compliance of the spacing of the copper busbars with the drawing requirements, making it difficult to tie the cable to the corresponding support rod.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A positioning fixture for a parallel-connected copper busbar includes a positioning frame and a positioning plate. The positioning frame includes a positioning bracket, a positioning base plate, and positioning rods. The positioning base plate is fixedly connected to the bottom of a T-shaped positioning bracket. The positioning bracket has a left waist-shaped hole and a right waist-shaped hole. The two positioning rods are respectively locked to the left waist-shaped hole and the right waist-shaped hole.

[0006] The positioning plate includes a positioning plate body, and hooks are respectively provided on both sides of the positioning plate body. Multiple open waist-shaped holes are opened on the surface of the positioning plate body. The width of the open waist-shaped holes is consistent with the inner diameter of the wiring holes on the connecting copper busbar on the parallel ring.

[0007] The positioning base plate on the positioning frame is used to connect with the end cover hole on the end plate. The two positioning rods are respectively connected to the hanging ears on both sides of the positioning plate. The open waist-shaped hole on the surface of the positioning plate and the wiring hole on the wiring copper busbar are simultaneously connected to the long screw to realize the positioning of the wiring copper busbar.

[0008] As a further improvement of the present invention, the number of open waist-shaped holes on the positioning plate body is the same as the number of wiring copper busbars on one side of the parallel loop.

[0009] As a further improvement of the present invention, the threaded portions on the two positioning rods are respectively locked to the left oblong hole and the right oblong hole by nuts.

[0010] As a further improvement of the present invention, the positioning base plate on the positioning frame is provided with mounting holes, and the mounting holes on the positioning base plate are connected to the end cover holes on the end plate by bolts.

[0011] As a further improved technical solution of the present invention, the long screw passes through the wiring hole on the wiring copper busbar and the open waist-shaped hole on the surface of the positioning plate, and the long screw is locked to the wiring hole on the wiring copper busbar by a nut and a washer, and the long screw is locked to the open waist-shaped hole on the surface of the positioning plate by a nut and a washer.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model has a simple structure and is easy to assemble with the end cover and wiring copper busbars, enabling precise positioning of the wiring copper busbars to meet drawing requirements. Similarly, the designed positioning plate can achieve precise positioning of different wiring copper busbar spacings for different models of marine generators. This solves a series of problems caused by the difficulty in positioning wiring copper busbars in existing technologies, resulting in wiring copper busbar spacing not meeting drawing requirements.

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0026] A positioning fixture for parallel-connected copper busbars, comprising, for example: Figure 4-5 The positioning frame 5 shown and as follows Figure 7-8 The positioning plate 12 shown is as follows: Figure 4-6 As shown, the positioning frame 5 includes a T-shaped positioning bracket 6, a positioning base plate 7, and positioning rods 8. The positioning base plate 7 is fixedly connected to the bottom of the vertical rod of the T-shaped positioning bracket 6. The horizontal rod of the positioning bracket 6 has symmetrically arranged left waist-shaped holes 1101 and right waist-shaped holes 1102. The two positioning rods 8 are respectively locked to the left waist-shaped holes 1101 and right waist-shaped holes 1102. The arrangement of the left waist-shaped holes 1101 and right waist-shaped holes 1102 allows the positioning rods 8 to move within the left waist-shaped holes 1101 and right waist-shaped holes 1102, adjusting the distance between the two positioning rods 8.

[0027] like Figure 7-8 As shown, the positioning plate 12 includes a positioning plate body 13, and the two sides of the positioning plate body 13 are respectively provided with hanging ears 14. The surface of the positioning plate body 13 is provided with multiple open waist-shaped holes 15; the width of the open waist-shaped holes 15 is consistent with the inner diameter of the wiring hole 401 on the wiring copper busbar 4.

[0028] The mounting holes on the positioning base plate 7 of the positioning frame 5 are used to connect with the end cover holes on the end plate 16. The two positioning rods 8 are respectively hooked to the lugs 14 on both sides of the positioning plate body 13, that is, the positioning rods 8 pass through the lugs 14. The open waist-shaped hole 15 on the surface of the positioning plate body 13 and the wiring hole 401 on the wiring copper busbar 4 are simultaneously connected to the long screw to realize the positioning of the wiring copper busbar 4. The open waist-shaped hole 15 on the surface of the positioning plate body 13 and the wiring hole 401 on both sides are locked to the long screw by nuts and washers. The long screw is not shown in the figure.

[0029] In this embodiment, the number of open waist-shaped holes 15 on the positioning plate body 13 and the number of connecting copper busbars 4 on one side of the ring 1 are the same and correspond one-to-one.

[0030] In this embodiment, the threaded portions at one end of each of the two positioning rods 8 are respectively locked to the left oblong hole 1101 and the right oblong hole 1102 by nuts 9 and M12 washers 10. The positioning rods 8 are hollow screws with a diameter of φ20*4, which can be fitted onto the lugs 14 on both sides of the positioning plate body 13.

[0031] In this embodiment, the positioning base plate 7 on the positioning frame 5 has mounting holes, and the mounting holes on the positioning base plate 7 are connected to the end cover holes on the end plate 16 by bolts. Mounting holes are fitted on the positioning base plate 7 according to the end cover bolts on the end plate 16 of the PMM1000 and PMM1500 bodies.

[0032] In this embodiment, the long screw passes through both the wiring hole 401 on the copper busbar 4 and the open oblong hole 15 on the surface of the positioning plate 13. The long screw is locked to the wiring hole 401 on the copper busbar 4 by a nut 9 and a washer 10, and the long screw is also locked to the open oblong hole 15 on the surface of the positioning plate 13 by a nut 9 and a washer 10. This achieves the positioning of the copper busbar 4 on one side of the loop 1. Figure 2 In Figure (b), there are 6 copper busbars 4 arranged on the left side of the connecting loop 1. One fixture from this embodiment is needed for positioning them; that is, the fixture is fixed to... Figure 9 At the position indicated by the rectangle on the left by the middle arrow; there are also 6 copper busbars 4 arranged on the right side of the connecting loop 1, which need to be positioned using another fixture of this embodiment, that is, the fixture of this embodiment is fixed on Figure 9 At the location indicated by the rectangle on the right side of the middle arrow, each copper busbar 4 is positioned and connected to the corresponding open oblong hole 15 via two long screws.

[0033] Before installing the fixture of this embodiment, multiple insulating support frames are bolted to the end cover 16. Each insulating support frame is detachably connected to an insulating positioning plate. Each semicircular ring in the parallel ring 1 is placed into a different positioning groove of the insulating positioning plate. The spacing and curvature between adjacent positioning grooves are adapted to the shape of the parallel ring 1 to achieve pre-positioning of the parallel ring 1. There are multiple insulating positioning plates. In order to position the copper busbars 4 on the parallel ring 1, the positions of the copper busbars 4 on both sides of the parallel ring 1 are fixed by the two fixtures of this utility model, which can prevent the inaccurate position of the copper busbars 4 caused by the tension of the parallel ring 1.

[0034] How to use:

[0035] 1. Align the mounting holes of the positioning base plate 7 on the positioning frame 5 with the end cover holes on the end plate 16, and install the positioning frame 5 at the position indicated by the arrow in the figure below using bolts.

[0036] 2. Adjust the positions according to the drawings so that the center positions of the two positioning rods 8 are aligned with the center mark line of the positioning frame 5, and the distance between the two positioning rods 8 is equal to the width of the positioning plate 13 (excluding the lugs 14, for example). Figure 4 (345mm in the middle), the two side lugs 14 of the positioning plate body 13 are respectively inserted into the two positioning rods 8; at the same time, the six open waist-shaped holes 15 on the positioning plate body 13 are aligned with the wiring holes 401 on the six wiring copper busbars 4 respectively.

[0037] 3. Take multiple long screws, and pass them through the wiring holes 401 on the copper busbar 4 and the open waist-shaped holes 15 on the surface of the positioning plate 13. The wiring holes 401 on the copper busbar 4 are locked to the long screws on both sides by nuts and washers. The open waist-shaped holes 15 on the surface of the positioning plate 13 are also locked to the long screws on both sides by nuts and washers. This achieves the connection between the positioning plate 12 and the multiple copper busbars 4. Since the copper busbar 4 has multiple wiring holes 401, each copper busbar 4 and the corresponding open waist-shaped hole 15 on the surface of the positioning plate 13 are fixed by two long screws (the two long screws are arranged in parallel). Following the above method, fix the positions of the two fixtures in this embodiment and the copper busbars 4 on both sides of the connecting ring 1.

[0038] After the above operations have fixed the positions of the copper busbars 4 at both ends of each semicircular ring, remove the insulating positioning plate and slide it along the arc of each semicircular ring in the parallel ring 1, sliding it out from one end of the semicircular ring. Then, wrap the outer surface of each semicircular ring in the parallel ring 1 and part of the outer surface of the copper busbar 4 with an insulating layer. Then, snap the multiple slots in the insulating positioning plate onto the semicircular rings in the parallel ring 1, and bind and fix the insulating positioning plate, the parallel ring 1 and the insulating support frame.

[0039] Since the connecting ring 1 is fixed in place, the position of the copper busbar 4 will not change due to the tension of the connecting ring 1. At this time, the fixture can be disassembled, that is, the fixture can be removed from the end cover and the copper busbar 4. Then, the lead wire, i.e. the cable, is welded onto the copper busbar 4. The end cover is installed on the end cover with bolts. The connecting ring 1 is located between the end cover and the end cover. The end cover has a cable outlet near the copper busbar 4 with the welded cable. There are many parallel support rods at the cable outlet. Since the position of the copper busbar 4 and the spacing between adjacent copper busbars 4 meet the requirements of the drawing, the cable on each copper busbar 4 can easily extend out of the end cover from the gap between the adjacent support rods or the gap between the support rod and the cable outlet. Then, each cable is tied to a different support rod to fix the cable. This solves the problem that the existing copper busbar 4 is not positioned accurately, i.e. it does not meet the requirements of the drawing. This causes the cable on the copper busbar 4 to deviate from the position of the support rod at the cable outlet of the end cover, making it difficult to extend the cable out of the end cover from the gap between adjacent support rods or the gap between the support rod and the cable outlet and to tie each cable to a different support rod.

[0040] For example: Figure 1 This is a schematic diagram of a series of interconnected loops. Figure 2 This is a diagram showing the spacing of the four copper busbars. Figure 3 This is a schematic diagram of a single copper busbar 4; the width of a single copper busbar 4 is 40mm, so the total width of the entire set of copper busbars 4 (6 copper busbars 4) can be calculated to be 40*6 + 25 + 20*4 = 345mm (i.e. Figure 2 The total width of the entire copper busbar 4 shown in Figure (a) is given, so the total length of the positioning plate 12 is designed to be 345mm. The two side lugs 14 have φ20 oblong holes. After inserting the φ20 positioning rod 8, the two ends of the positioning plate 12 can be positioned. The width of the oblong holes 15 on the positioning plate 12 is determined according to... Figure 3 The size and length of the wiring hole 401 on the copper busbar 4 are designed according to... Figure 3 The center hole spacing design involves inserting an M12 long screw (connecting two wiring holes in each copper busbar 4 to corresponding open oblong holes 15 at different positions via the long screw) into the wiring hole 401 in the copper busbar 4 and the open oblong hole 15 on the positioning plate 12. After securing it on both sides with washers 10 and nuts 9, precise positioning of the copper busbar 4 is achieved, conforming to the drawing requirements. Similarly, positioning plates 12 of different sizes can be designed to achieve precise positioning of different copper busbar spacings for different models of marine generators.
