Description

Technical Field

[0001] The present invention relates to the technical field of copper bar welding, and specifically provides a copper bar welding and fixing tooling and a copper bar welding device. Background Art

[0002] A copper bar, also known as a copper busbar or a copper busbar, is made of copper and is a long conductor with a rectangular or chamfered (rounded) rectangular cross-section (now generally rounded copper bars are used to avoid tip discharge). It plays the role of conveying current and connecting electrical equipment in a circuit.

[0003] Through retrieval, Chinese Patent Publication No. CN118455890A discloses a copper bar welding and fixing tooling and a copper bar welding device. The copper bar welding and fixing tooling includes a frame base, an operating table, a forming support plate, and a pressing mechanism; the operating table has a first surface for placing the copper bar; the forming support plate is embedded in the center of the operating table; the pressing mechanism is arranged on the frame base, and the pressing mechanism includes two pressing components. The projections of the two pressing components on the first surface are located on both sides of the forming support plate; each pressing component includes a first driving member and a pressing plate. The pressing component is configured to switch between a pressing state and a releasing state, so that the pressing plate is lifted and lowered under the drive of the first driving member to press the copper bar on the operating table or release the copper bar; wherein, a flow channel for fluid to pass through is arranged inside the pressing plate and / or inside the operating table. The copper bar welding and fixing tooling provided by the embodiment of this application can improve the conductivity and quality of the welded busbar, reduce the labor cost of welding, and accelerate the welding rate;

[0004] Regarding the above related technologies, the inventor believes there are the following defects:

[0005] 1. When brazing a copper bar, due to the flat shape of the copper bar wire, when welding the copper bar wire, affected by the fluidity of the brazing filler metal, the brazing filler metal cannot penetrate into the inside of the fitting position of the copper bar wire. Therefore, the welding position of the copper bar wire is not firm and there is a situation of false welding. After being energized, it will not only cause oxidation and corrosion at the welding position, but also affect the conductivity of the copper bar.

[0006] 2. The surface of the copper bar cannot be cleaned before welding. Since there will be oil stains and oxide films on the surface of the copper bar, the connectivity of the weld position will be affected during welding, and the firmness of the weld will be affected.

[0007] 3. It is not convenient to adjust the position of the copper bar during welding. The welding length cannot be determined in advance before welding. Therefore, not only the welding length cannot be determined in advance, but also the copper bar cannot be clamped and fixed after the position is changed. Summary of the Invention

When the column 92 and the polishing wire 93 rise, they penetrate through the holes of the isolation belt 33. The dirt removing mechanism 9 uses the electric telescopic rod 8 to push the lifting plate 91 to rise, so that the polishing wire 93 at the top of the column 92 can approach the copper bar welding gap. Driven by the square shaft 7, the column 92 drives the polishing wire 93 to rotate, so that the oil stains and oxide layers on the surface of the copper bar passing through the polishing wire 93 can be wiped and polished.

The output belt 143 is sleeved outside the first pulley 152. The first gear 151 is meshed with the steering half gear 16. The toggle shaft 15 can push the steering half gear 16 to rotate, providing power for the copper bar to turn.

[0042] The steering half gear 16 is fixedly connected with the positioning component 12. Inside the positioning component 12, there is a guide rod 17 slidably connected. At the end face of the guide rod 17, there is a clamping shell 18 fixedly connected. At the lower end of the clamping shell 18, there is a stretching motor 19 fixedly connected. The outer shape of the clamping shell 18 is in the shape of a semi-cylindrical. At the edge of the upper plane of the clamping shell 18, there is a clamping groove 181.
