Description

Technical Field

[0001] This utility model relates to the field of copper busbar technology, specifically to a copper busbar limiting punching tool. Background Technology

[0002] A copper busbar, also known as a current bus or busbar, is a long conductor made of copper with a rectangular or rounded rectangular cross-section. It serves to transmit current and connect electrical equipment in a circuit. To facilitate connection between the copper busbar and other electrical devices, holes are usually drilled or punched in the copper busbar as needed.

[0003] For example, the copper busbar limiting punching fixture disclosed in application number 202420999738.2 can punch the copper busbar workpiece to be processed on the positioning groove by means of a punching head insert with a different diameter. The compression spring is used to buffer the impact force of the punching head when punching the copper busbar workpiece to be processed, and to extend the service life of the bottom die base.

[0004] However, existing copper busbar limiting punching fixtures only punch copper busbars one by one when in use, which prevents them from punching multiple copper busbars sequentially, reducing their punching and processing efficiency. Furthermore, they cannot easily and effectively adjust the punching position, thus failing to perform effective punching and reducing their usage and work efficiency. Therefore, we propose a copper busbar limiting punching fixture. Utility Model Content

[0017] Example 1 like Figures 1 to 5 As shown, a copper busbar limiting punching fixture includes a base 1, a convex platform 16 is provided on the top of the base 1, and L-shaped plates 2 are respectively bolted to the bottom of the convex platform 16 near the left and right sides. The bottom of the L-shaped plates 2 is bolted to the top of the base 1. Positioning blocks 5 are slidably connected to the top of the inner cavity of the two L-shaped plates 2. A screw hole tube 21 is connected through the positioning block 5, and a through hole 17 matching the screw hole tube 21 is opened on the convex platform 16. In this embodiment, a bidirectional lead screw 3 matching the two screw tubes 21 is inserted into the perforation 17. The two ends of the bidirectional lead screw 3 pass through the screw tubes 21 and are movably connected to the L-shaped plate 2 through bearings. The two ends of the bidirectional lead screw 3 are connected to the rotating wheel 4 through the inner ring of the bearing. An inverted U-shaped plate 7 is fitted in the middle of the convex platform 16. Electric jacks 15 are bolted to the bottom of the inverted U-shaped plate 7 near the left and right sides. The bottom end of the electric jack 15 is bolted to the top of the base 1. This can effectively avoid punching the copper busbars one by one, so that multiple copper busbars can be punched sequentially, improving the punching efficiency and processing efficiency.

[0018] Example 2 like Figures 1 to 5As shown, a rectangular groove 8 is provided on the top of the inverted U-shaped plate 7. A movable plate 10 is slidably connected in the rectangular groove 8. Sliders are connected to the front and rear sides of the movable plate 10 by bolts. Slider grooves matching the sliders are provided on the inner walls of the front and rear sides of the rectangular groove 8. A threaded hole is provided on the movable plate 10, and a threaded rod 9 passes through the threaded hole. The left and right ends of the threaded rod 9 are movably connected to the inner wall of the rectangular groove 8 by bearings. A servo motor 14 is connected to the right side of the inverted U-shaped plate 7 by bolts. The right end of the threaded rod 9 passes through the inner ring of the bearing and is connected to the output shaft of the servo motor 14. Implementation plan: The top of the convex platform 16 is provided with grooves 13 near the front and rear sides. The chip collection box 6 is fitted inside the grooves 13 and the top of the chip collection box 6 is open. Rectangular blocks 18 are bolted to the inner walls of the front and rear sides of the chip collection box 6. The bottom of the moving plate 10 is bolted to the rotary motor 20. The bottom of the output shaft of the rotary motor 20 is bolted to the rotating plate 19. The top of the rotating plate 19 is bolted to the electric push rod 11. The rear end of the electric push rod 11 is bolted to the punching machine 12, which allows for convenient and effective adjustment of the punching position, thereby enabling effective punching and improving its usage efficiency and work efficiency. In this embodiment, the electric push rod 11, punching machine 12, servo motor 14, electric jack 15 and rotary motor 20 are electrically connected to control switches via power lines, and their matching control components can be purchased directly together with them. Working Principle: In this technical solution, two copper busbars are first placed on top of two chip collection boxes 6. Then, rotating the rotating wheel 4 causes two bidirectional lead screws 3 to drive two threaded tubes 21 to close together. The two threaded tubes 21 then drive two positioning blocks 5 to close together, clamping the copper busbars. Next, the extension and retraction of the electric push rod 11 moves the punching machine 12 back and forth, adjusting its position. The forward or reverse rotation of the servo motor 14 drives the moving plate 10 to move left and right within the rectangular groove 8 via the threaded rod 9, allowing for adjustment of its left and right position and continuous punching, enabling convenient alignment of the punched holes. The device is effectively adjusted to enable efficient punching, improving its usage and work efficiency. The electric jack 15 retracts and drives the punching machine 12 downward through the inverted U-shaped plate 7 to achieve punching. After the copper busbar on the rear side is punched, the rotary motor 20 drives the rotating plate 19 to rotate. The rotating plate 19 drives the punching machine 12 to rotate to the front side through the electric push rod 11. Repeating the above operation can effectively avoid punching the copper busbar one by one, thus enabling it to punch multiple copper busbars sequentially, improving its punching and processing efficiency. The waste generated during punching falls into the chip collection box 6 for collection.
