The limiting groove is slidably connected to the guide strip. The length of the limiting groove occupies four-fifths of the entire arc groove. The mounting plate is provided with bolts two that are fixedly connected to the fixing plate. Therefore, a toothed plate is fixedly connected to the middle position of the bottom of the fixing plate. The length of the toothed plate is the same as the length of the fixing plate. Sliding holes are fixedly connected to both sides of the middle bottom of the fixing plate.

Detailed Implementation
[0015] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0016] like Figures 1 to 8As shown, a punching device for copper wire busbars suitable for processing various hole diameters includes a base mechanism 1, on which a pushing mechanism 2, a punching mechanism 3, and a clamping mechanism 4 are sequentially mounted. Figures 3 to 5 As shown, the stamping mechanism 3 includes a base plate 303, on which multiple stamping columns 302 are slidably connected. Each stamping column 302 is provided with an upper cover plate 301 fixedly connected to the base plate 303. The upper cover plate 301 has multiple arc grooves 3012 of different diameters at one end facing the stamping column 302. Bolts 3011 fixedly connected to the base plate 303 are fixed at both ends of the upper cover plate 301. The diameters of the multiple stamping columns 302 are all different. Each stamping column 302 includes a column body 3021. An arched plate 3022 is fixedly connected to one end of the column body 3021. The arc diameter on one side of the arched plate 3022 is the same as the diameter of the connecting column body 3021. A magnet 3023 is fixedly connected to the arc part of the arched plate 3022. The main function of the magnet 3023 is to attract all the stamping columns 302 to the baffle 30351 and keep all the stamping columns 302 flush. A guide strip 3024 is fixedly connected to the bottom column 3021 of the magnet 3023. The guide strip 3024 occupies one-fifth of the column 3021. The base plate 303 includes a fixing plate 3035. A baffle 30351 is fixedly connected to one side of the fixing plate 3035. The baffle 30351 abuts against the arched plate 3022. A mounting plate 3031 is fixedly connected to the upper part of the fixing plate 3035. The mounting plate 3031 has the same number of arc grooves 3032 as the stamping column 302. The arc grooves 3032 are slidably connected to the stamping column 302. The diameter of the multiple arc grooves 3032 is the same as that of the stamping column 302 to which they are mounted. The bottom of the multiple arc grooves 3032 is provided with limiting grooves 3033. The limiting grooves 3033 are slidably connected to the guide strips 3024. The main function is to prevent the stamping column 302 from rotating on the arc grooves 3032. The length of the limiting grooves 3033 accounts for four-fifths of the entire arc grooves 3032. The mounting plate 3031 is provided with bolts 3034 that are fixedly connected to the fixing plate 3035. Therefore, a toothed plate 3036 is fixedly connected to the middle position of the bottom of the fixing plate 3035. The length of the toothed plate 3036 is the same as the length of the fixing plate 3035. Sliding holes 3037 are fixedly connected to both sides of the middle bottom of the fixing plate 3035.
[0017] like Figure 2As shown, the base mechanism 1 includes a base 101, with a frame 103 fixedly connected in the middle of the base 101. Two slide rods 104 are fixedly connected on the frame 103. The length direction of the slide rods 104 is parallel to the length direction of the base 101. The slide rods 104 are slidably connected to the sliding holes 3037, so that the fixing plate 3035 can slide on the slide rods 104. A servo motor 108 is fixedly connected in the middle of the frame 2 103. A gear 109 is fixedly connected to the rotating end of the servo motor 108. The gear 109 meshes with the gear plate 3036 for transmission. A frame 1 102 is fixedly connected to the base 101 on one side of the frame 2 103. Four fixed brackets 105 are fixedly connected to the edge of the base 101 on the other side of the frame 2 103. The fixed brackets 105 are triangular in shape. The function of the fixed brackets 105 is to abut against the clamping mechanism 4 when the clamping mechanism 4 clamps the copper wire busbar and the stamping mechanism 3 makes a hole, so as to prevent the clamping mechanism 4 from deforming due to excessive force from the stamping mechanism 3. A threaded hole 106 is opened in the middle of the base 101 between the frame 2 103 and the fixed brackets 105. Slide rod holes 107 are opened on the base 101 on both sides of the threaded hole 106. The sliding rod holes 107 on both sides limit the telescopic plate 405 to only extend and retract vertically, while the threaded hole 106 in the middle allows the lead screw 2 409 at the bottom of the telescopic plate 405 to rotate.
[0018] like Figure 6 As shown, the clamping mechanism 4 includes a telescopic plate 405, which is L-shaped. A second lead screw 409 is rotatably connected to the bottom center of the telescopic plate 405. The second lead screw 409 is threadedly connected to the first threaded hole 106. Moving the telescopic plate 405 up and down can adjust the longitudinal height of the copper wire busbar drilling. Telescopic plates 405 are fixedly connected to telescopic columns 406 at both ends of the bottom. The telescopic columns 406 are slidably connected to the sliding rod holes 107. Two long slots 404 are opened at the bottom of the telescopic plates 405. One of the long slots 404 has a through hole 407 at one end. Sliding plates 401 are slidably connected in the two long slots 404. Limiting blocks 402 are fixedly connected to the bottom of the sliding plates 401. The limiting block 402, which is slidably connected to the long slot 404 with the through hole 407, has a threaded hole 403. A lead screw 408 is threaded in the threaded hole 403. The lead screw 408 is slidably connected to the through hole 407. The main function of the lead screw 408 is to position the copper busbar and prevent the copper busbar from sliding and shifting during drilling, thus preventing inaccurate drilling spacing. The sliding plate 401 and the telescopic plate 405 have the same groove in the middle of their side plates. The groove width is greater than the diameter of the maximum stamping column 302. The advantage of this is that the copper wire busbar will not be deformed during the copper wire busbar punching operation.
[0019] A pushing mechanism 2 is fixedly connected to the frame 102, such as Figures 7 to 8As shown, the jacking mechanism 2 includes a hydraulic jacking device 201. A telescopic shaft 202 is slidably connected to the side of the hydraulic jacking device 201 near the frame 103. A C-shaped buckle 203 is fixedly connected to one end of the telescopic shaft 202. The opening of the C-shaped buckle 203 faces the base 101, and the interior of the C-shaped buckle 203 abuts against the arched plate 3022, pushing the stamping column 302 to move. The width of the C-shaped buckle 203 is consistent with the diameter of the middle stamping column 302 among the multiple stamping columns 302. This allows for maximum pushing and stretching of each stamping column 302. Furthermore, when the C-shaped buckle 203 compresses or stretches the stamping column 302, the axis of the telescopic shaft 202 is collinear with the axis of the stamping column 302, allowing all the force on the telescopic shaft 202 to be transferred to the stamping column 302, thus improving the service life of the stamping column 302.
[0020] Multiple stamping columns 302 have slots near the upper part of the arched plate 3022. The slots of the multiple stamping columns 302 are flush. The main reason for this design is that, without affecting the structural strength, when the multiple stamping columns 302 on the stamping mechanism 3 move left and right, the stamping columns 302 will not affect the C-shaped buckle 203, that is, they will not come into contact with the C-shaped buckle 203.
[0021] Those skilled in the art can use existing technologies they possess, such as installing appropriate mechanical limit switches or photoelectric sensors, to limit the specified positions of each actuator during the following operation process; to achieve automated operation, this utility model can use numerical control technology or PLC to control the actions of each actuator.
[0022] Working process: Place the horizontally arranged copper wires to be drilled on the telescopic plate 405. By rotating the lead screw 408, the sliding plate 401 and the telescopic plate 405 clamp the copper wires. Align the drilling position with the slot on the side of the telescopic plate 405. Adjust the vertical height of the drilling position on the copper wires by rotating the lead screw 409.
[0023] After the copper wire busbar is installed, the servo motor 108 drives the gear 109 to rotate, moving the stamping column 302, which matches the punching diameter, in the stamping mechanism 3 to the slot of the sliding plate 401. The servo motor 108 then stops rotating. The hydraulic jacking device 201 in the jacking mechanism 2 activates, extending the telescopic shaft 202 outward. The C-shaped buckle at the front end of the telescopic shaft 202 abuts against the stamping column 302 and moves it towards the copper wire busbar, beginning the punching operation. After the stamping column 302 has finished punching the copper wire busbar, the hydraulic jacking device 201 activates, retracting the telescopic shaft 202 backward. The C-shaped buckle drives the stamping column 302 to retract backward, while the copper wire busbar is fixed by the clamping mechanism 4 and no longer moves. The material squeezed out of the copper wire busbar by the punching column 302 is carried out from the hole.
[0024] When different hole diameters need to be drilled into the copper busbar, the servo motor 108 simply drives the stamping mechanism 3 to move, aligning the differently controlled stamping pins 302 with the slots in the sliding plate 401. Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
