Description

Technical Field

[0001] This utility model relates to the field of positioning fixtures, specifically to a busbar welding positioning fixture. Background Technology

[0002] Busbars are conductive devices used in power systems to centrally distribute current, commonly found in new energy battery packs, distribution cabinets, and electric vehicles. Their welding quality directly affects conductivity and system safety, and precise positioning before welding is crucial to ensuring weld consistency. Busbar welding positioning fixtures are specialized tooling used to fix the busbar position and ensure alignment accuracy during the welding process. Clamping is typically achieved through the coordinated action of a clamping mechanism and a positioning structure.

[0003] However, existing positioning fixtures have significant drawbacks in practical applications: traditional fixtures mostly adopt a single clamping rod design, and the clamping force is concentrated in a local area. When the busbar is heated and expanded or vibrates during welding, it is easy to shift or even warp due to uneven stress distribution, making the busbar clamping unstable. The contact surface between the clamping block and the busbar is flat, and the contact area is insufficient during clamping. The friction is insufficient to resist welding impact. It only relies on clamping in one direction and lacks a horizontal limiting structure. The busbar is prone to lateral slippage under welding thermal stress, and radial shaking occurs after clamping, which aggravates the cumulative displacement error and easily leads to the busbar loosening and detachment after clamping. Utility Model Content

A plurality of positioning rods for positioning the busbar are provided on one end of the base. One end of the positioning rod extends to the outside of the base.

[0006] Furthermore, one end of the base and the base plate is provided with several screw holes, and the surface of the base is provided with several screws. The base and the base plate are threaded together by the screws passing through the screw holes.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The following is combined Figures 1-6 The present invention provides a detailed description of the busbar welding positioning fixture:

[0024] A busbar welding positioning fixture includes a base 1 and a base plate 2. A clamping block 10 is provided on the top of the base 1. One end of the clamping block 10 is recessed inward to form a sliding groove 11. The sliding groove 11 extends along the height direction of the clamping block 10. A detachable slider 12 is provided in the sliding groove 11. The slider 12 is provided with a hollow square groove 13 for clamping the busbar. A plurality of clamping rods 16 are provided on one end of the clamping block 10. One end of the clamping rod 16 passes through the clamping block 10 and extends to the outside of the clamping block 10. One end of the clamping rod 16 extends outward to form a clamping part 18. A plurality of positioning rods 19 for positioning the busbar are provided on one end of the base 1. One end of the positioning rod 19 extends to the outside of the base 1.

[0025] The base 1 and base plate 2 are provided with a plurality of screw holes 4 at one end. The surface of the base 1 is provided with a plurality of screws 5. The base 1 and base plate 2 are threadedly connected by screws 5 passing through the screw holes 4. A support plate 6 is vertically provided at one end of the base 1. Fastening bolts 9 are provided on the surface of the support plate 6. The support plate 6 is threadedly connected to the base 1 by the fastening bolts 9. A pressing block 7 is provided at one end of the support plate 6. The pressing block 7 is rotatably connected to the support plate 6. A first spring 8 is provided on the side of the base 1. The pressing block 7 is connected to the base 1 via the first spring 8. Fasteners 15 are provided at both ends of the clamping block 10. The slider 12 is connected to the clamping block 10 via the fasteners 15. A second spring 17 is provided in the clamping part 18. A second spring 17 is provided, one end of which is connected to the clamping part 18, and the other end of which is connected to the clamping block 10. One end of the base 1 extends outward to form a placement platform 3 for supporting the busbar. The placement platform 3 extends to the outside of the base 1. A plurality of fixing rods 20 are provided at one end of the base 1. The clamping block 10 is fitted with a fastening sleeve 14. A fastening seat 22 is provided at the bottom of the clamping block 10. One end of the fixing rod 20 extends to the outside of the clamping block 10. The fixing rod 20 is slidably connected to the fastening sleeve 14. A third spring 21 is provided at one end of the base 1. The third spring 21 is arranged around the fixing rod 20. One end of the third spring 21 is connected to the base 1, and the other end of the third spring 21 is connected to the fastening seat 22.

[0026] In this embodiment, the positioning rod 19 extends to the outside of the base 1 and, together with the extended placement platform 3, provides multiple physical limits for the busbar, ensuring that the position is fixed during welding and preventing the busbar from shifting during welding. The screw 5 connects the base 1 and the base plate 2 with threads. The detachable design facilitates fixture maintenance and component replacement, reducing long-term usage costs. By setting several positioning rods 19 on the base 1, the hole positions of the busbar can be positioned, thereby preventing loosening and shifting of the busbar during welding and avoiding inaccurate welding of the busbar.

[0027] The busbar welding positioning fixture of this embodiment achieves stable clamping of the busbar by providing a plurality of clamping rods 16 on the clamping block 10 and a plurality of positioning rods 19 on the base 1, in conjunction with the hollow square groove 13 provided on the slider 12, thereby avoiding unstable clamping and preventing the busbar from easily loosening and detaching after clamping.

[0028] When processing the busbar, the pressing block 7 is pressed manually, which compresses the first spring 8. This causes the clamping block 10 to slide along the fixed rod 20, which in turn causes the clamping block 10 to move the clamping rod 16 away from the base 1. The busbar is then placed on the base 1 and the placement platform 3, with the holes on the busbar aligned with the positioning rod 19 on the base 1. The positioning rod 19 passes through the holes on the busbar to position it. After the pressing block 7 is released, the hollow square groove 13 on the slider 12 clamps one end of the busbar. The clamping rod 16 on the clamping block 10 holds the busbar stably. Through multi-point physical limiting, the position of the busbar is ensured to be fixed during welding.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
