Description

Technical Field

[0001] This utility model relates to the field of copper-aluminum busbar welding technology, and more specifically to a copper-aluminum busbar welding clamping device. Background Technology

[0002] In fields such as power equipment, new energy batteries, electric vehicles and industrial power distribution systems, copper-aluminum composite busbars are widely used as a key conductive connection element because they combine the high conductivity of copper with the lightweight and low-cost advantages of aluminum.

[0003] A search revealed Chinese patent CN219425880U, which discloses an integrated automatic brazing machine for copper-aluminum welding. This device uses a motor to drive other parts to rotate the copper-aluminum component and adjust the welding angle without disassembling it. This reduces the number of steps and makes adjustment convenient. However, due to the varying thicknesses of copper-aluminum bars, the device uses a hydraulic cylinder to clamp and fix them. This makes it difficult to control the force when dealing with copper-aluminum bars of different thicknesses, which can easily damage the copper-aluminum bars. Utility Model Content

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Reference Figures 1-4This utility model provides a copper-aluminum busbar welding clamping device, including a workbench 1. A housing 2 is bolted to the upper surface of the workbench 1. A cylinder 3 is bolted to the top outer wall of the housing 2. One end of the output shaft of the cylinder 3 passes through the top inner wall of the housing 2 and is bolted to a frame 4. An integrated automatic brazing machine body 5 is installed inside the frame 4. A base 6 is bolted to the middle of the upper surface of the workbench 1. A clearance opening 7 is provided on both sides of the upper surface of the workbench 1 and on both sides of the base 6. A limiting slide frame 8 is provided in each of the two clearance openings 7. A limiting slider 9 is slidably connected in the limiting slide frame 8. An L-shaped bracket 10 is bolted to the upper surface of the limiting slider 9. The upper surface of the L-shaped bracket 10 is bolted to the upper surface of the limiting slider 9. A fixed base 11 is fixedly connected, and a fixed plate 12 is fixedly connected to the upper surface of the fixed base 11 by bolts. A threaded rod 13 is threaded through the fixed plate 12, and a stepped clamping block 14 is rotatably connected to one end of the threaded rod 13 via a bearing. U-shaped blocks 20 are fixedly connected to both sides of the fixed plate 12 by bolts. Two symmetrical guide rods 21 that cooperate with the U-shaped blocks 20 are fixedly connected to one side of the stepped clamping block 14 by bolts. To facilitate the installation of copper and aluminum busbars, a mounting platform 17 for placing copper and aluminum busbars is fixedly connected to the upper surface of the workbench 1 and located in front of the base 6 by bolts. Two symmetrical connecting rods 18 are fixedly connected between the opposite sides of the base 6 and the mounting platform 17 by bolts. The two connecting rods 18 are rotatably connected by a bearing. Multiple rotating rollers 19 with equal intervals are connected in a dynamic connection. The upper surface of the mounting platform 17, the upper surface of the base 6, and the top of the rotating rollers 19 are all at the same height from the worktable 1. After the L-shaped bracket 10 extends onto the mounting platform 17 outside the housing 2, copper and aluminum busbars are placed on the mounting platform 17, one on the left and one on the right. Then, the two threaded rods 13 are rotated simultaneously, which drives the two stepped clamping blocks 14 to move closer to each other, thereby clamping the copper and aluminum busbars so that both ends of them are embedded in the stepped grooves of the stepped clamping blocks 14. When the copper and aluminum busbars are in close contact, the clamping of the copper and aluminum busbars is completed. Then, the multi-section electric push rod 16 is activated to retract, causing the limit slider 9 to slide in the opposite direction along the limit sliding frame 8. At the same time, the copper and aluminum busbars are clamped together. The contact end of the aluminum busbar moves along the rotating roller 19. Once it reaches the base 6, the multi-section electric push rod 16 stops. After the copper and aluminum busbar is fed onto the base 6, the cylinder 3 is activated to extend, thereby driving the frame 4 and the integrated automatic brazing machine body 5 downwards. When the bottom of the integrated automatic brazing machine body 5 contacts the copper and aluminum busbar, welding can begin. The stepped clamping block 14 and the threaded rod 13 rotatably connected to it allow control of the clamping force during the clamping process, preventing over-clamping and damage to the copper and aluminum busbar. Furthermore, the stepped clamping block 14 allows for clamping operations on copper and aluminum busbars of different thicknesses. The connecting rod 18 and rotating roller 19 allow for control during the process of feeding the copper and aluminum busbar onto the base 6.The bottom is supported to prevent misalignment of the contact ends due to its own weight, which would affect the welding accuracy.

[0022] Among them, the integrated automatic brazing machine body 5 belongs to the category of electrical products, and the technology is relatively mature. Its specific structure is not within the scope of this patent.

[0023] In this invention, the bottoms of the two limiting sliders 9 are fixedly connected to U-shaped rods 15 by bolts. Multiple electric push rods 16 are fixedly connected to the inner wall of one side of the worktable 1 by bolts, and the output end of the multiple electric push rods 16 is fixed to the inner wall of one side of the U-shaped rods 15. Before welding the copper-aluminum busbar, the multiple electric push rods 16 are extended. During the extension of the multiple electric push rods 16, the limiting sliders 9 are driven to slide along the limiting slide frame 8 through the U-shaped rods 15, thereby driving the L-shaped bracket 10 to extend onto the mounting platform 17 on the outside of the housing 2. With the U-shaped rods 15 and the multiple electric push rods 16, it is convenient to load and unload the workpiece, realizing the automated loading and unloading operation of the copper-aluminum busbar, which not only reduces labor costs, but also effectively improves processing efficiency and quality.

[0024] The use of this utility model involves the following steps:

[0025] S1: Before welding the copper-aluminum busbar, start the multi-section electric push rod 16 to extend. During the extension of the multi-section electric push rod 16, the U-shaped rod 15 drives the limiting slider 9 to slide along the limiting slide frame 8, thereby causing the L-shaped bracket 10 to extend onto the mounting platform 17 on the outside of the housing 2.

[0026] S2: After extending the L-shaped bracket 10 onto the mounting platform 17 outside the housing 2, place the copper and aluminum busbars on the mounting platform 17, one on the left and one on the right. Then, rotate the two threaded rods 13 simultaneously, thereby driving the two stepped clamping blocks 14 to move closer to each other, thereby clamping the copper and aluminum busbars so that both ends of them are embedded in the stepped grooves of the stepped clamping blocks 14. When the copper and aluminum busbars are in close contact, the clamping of the copper and aluminum busbars is completed.

[0027] S3: Then, the multi-section electric push rod 16 is activated to retract, causing the limit slider 9 to slide in the opposite direction along the limit slide frame 8. At the same time, the contact ends of the copper busbar and aluminum busbar move along the rotating roller 19. When it moves onto the base 6, the multi-section electric push rod 16 can be stopped.

[0028] S4: After the copper-aluminum busbar is delivered to the base 6, the cylinder 3 can be activated to extend, thereby driving the frame 4 and the integrated automatic brazing machine body 5 to move downward. When the bottom of the integrated automatic brazing machine body 5 contacts the copper-aluminum busbar, the welding operation can be performed.

[0029] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
