AI Technical Summary
[0003]现有小规格铜排冲孔加工方式人工看尺划线，难免看错刻度出现误差，人工手动敲打样冲点，铜排加工量稍大时就需多人参入，导致人工成本高、生产效率低，而这类小规格的铜排通常都只在二端冲孔，孔的相对位置都是固定的，为此提出一种铜排批量冲孔工装
[0009]本实用新型可彻底省去现有小规格铜排冲孔加工中人工划线、打样冲点、探针对准样冲点的繁琐步骤，借助槽口对铜排的定位作用，待加工铜排放入槽口并推至槽口底部后，其待冲孔位置可直接对准机床冲头，无需人工调整；同时通过向上竖折边实现安全防护，通过多固定孔配合螺栓实现工装稳固安装，最终实现同规格铜排的批量、精准、安全冲孔，有效解决现有技术中人工成本高、生产效率低、孔位精度差、操作安全性低的问题。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of batch punching technology for copper busbars, specifically a tooling for batch punching copper busbars. Background Technology
[0002] In the production of copper busbars in electrical assembly plants, when the busbar width is 20mm or less, the material area is too small to be clamped, and advanced CNC machine tools cannot be used for punching. Usually, workers use a square to draw lines, find the position, make a sample punching point, and then use the probe of an ordinary processing machine tool to align with the sample punching point to punch the hole.
[0003] The existing method for punching small-sized copper busbars involves manually marking lines with a ruler, which inevitably leads to errors due to misreading the scale. Manually tapping the punch points also requires multiple people to participate when the copper busbar processing volume is slightly larger, resulting in high labor costs and low production efficiency. Since these small-sized copper busbars are usually punched only at both ends, and the relative positions of the holes are fixed, a new tooling for batch punching copper busbars is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a tooling for batch punching of copper busbars to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a copper busbar batch punching fixture, comprising a fixture body made of sheet metal, the fixture body being a flat plate structure, the flat plate structure having a slot for accommodating the copper busbar to be processed, the size of the slot being adapted to the cross-sectional size of the copper busbar to be processed, one side of the slot having an upwardly extending vertical folded edge, the height of the upwardly extending vertical folded edge being greater than the thickness of the copper busbar to be processed, the end of the flat plate structure having a downwardly extending downward folded edge, a first fixing hole being provided at the corner of the flat plate structure, a second fixing hole and a third fixing hole being provided on the downward folded edge, the first fixing hole, the second fixing hole and the third fixing hole being adapted to the internal threaded hole of the worktable of the copper busbar punching machine tool, for fixing the fixture body to the worktable of the machine tool by bolts.
[0006] Preferably, the first fixing hole, the second fixing hole, and the third fixing hole are all through holes, and the diameter of the through holes matches the outer diameter of the suitable bolt.
[0007] Preferably, the upward vertical fold is integrally formed with the flat plate structure, and the downward fold is integrally formed with the flat plate structure.
[0008] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0009] This invention completely eliminates the tedious steps of manual marking, pattern making, and probe alignment in the punching of small-sized copper busbars. By using the slot to position the copper busbar, the copper busbar to be punched is placed into the slot and pushed to the bottom of the slot, and its punching position can be directly aligned with the machine tool punch without manual adjustment. At the same time, the upward vertical folding edge provides safety protection, and multiple fixing holes and bolts ensure stable installation of the tooling. Ultimately, it enables batch, precise, and safe punching of copper busbars of the same specification, effectively solving the problems of high labor costs, low production efficiency, poor hole position accuracy, and low operational safety in the existing technology. Attached Figure Description
[0010] Figure 1 This is a schematic diagram of the structure of this utility model when it is installed on a machine tool workbench.
[0011] The components include: 1. Tooling body; 2. Machine tool worktable; 3. Copper busbar to be processed; 11. First fixing hole; 12. Second fixing hole; 13. Third fixing hole; 14. Upper vertical folded edge. Detailed Implementation
[0012] 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.
[0013] This utility model provides the following technical solution:
[0014] Please see Figure 1 A batch punching fixture for copper busbars includes a fixture body 1 made of sheet metal. The fixture body 1 is a flat plate structure with a slot for accommodating the copper busbars 3 to be processed. The size of the slot is adapted to the cross-sectional size of the copper busbars 3 to be processed. One side of the slot has an upwardly extending vertical flange 14, the height of which is greater than the thickness of the copper busbars 3 to be processed. The end of the flat plate structure has a downwardly extending flange. A first fixing hole 11 is provided at the corner of the flat plate structure, and a second fixing hole 12 and a third fixing hole 13 are provided on the downward flange. The first fixing hole 11, the second fixing hole 12 and the third fixing hole 13 are all adapted to the internal threaded holes of the worktable 2 of the copper busbar punching machine tool, and are used to fix the fixture body 1 to the worktable 2 of the machine tool by bolts.
[0015] The first fixing hole 11, the second fixing hole 12 and the third fixing hole 13 are all through holes, and the diameter of the through holes matches the outer diameter of the suitable bolt.
[0016] The upward vertical fold 14 is integrally formed with the flat plate structure, and the downward fold is integrally formed with the flat plate structure.
[0017] Using the above technical solution, the fixture body 1 is placed next to the preset stamping area of the worktable 2 of the copper busbar punching machine, so that the first fixing hole 11, the second fixing hole 12, and the third fixing hole 13 are respectively aligned with the existing internal threaded holes on the worktable 2; bolts with the appropriate hole diameter are taken, passed through the first fixing hole 11, the second fixing hole 12, and the third fixing hole 13 respectively, and screwed into the internal threaded holes of the worktable 2. The bolts are tightened with a wrench to ensure that there is no relative looseness between the fixture body 1 and the worktable 2. The operator holds the copper busbar 3 to be processed. Place one end of the copper busbar 3 smoothly into the slot along its length, and then push the copper busbar 3 to be processed until its end touches the bottom of the slot. At this point, the punching position of the copper busbar 3 is exactly aligned with the machine tool punch. After the operator confirms that his / her hand is outside the upward vertical fold 14 to avoid his / her hand entering the punching area, he / she steps on the machine tool start switch. The machine tool punch moves down to complete one punching operation. After a single punching operation is completed, the operator takes out the punched copper busbar from the slot, and then takes a new copper busbar 3 to be processed. Repeat the above operation to continuously complete the batch punching of copper busbars of the same specification and with the same hole position requirements.
[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
