Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing and processing technology, specifically a multi-hole elastic punching device. Specifically, it utilizes pressure to cause the punch head to impact the workpiece, achieving rapid and accurate positioning for multi-plate, multi-hole processing. Background Technology

[0002] When processing multiple workpieces, each with multiple holes, on-site (see...) Figure 2 There are three holes (12), and each hole needs to be marked and positioned. This results in low work efficiency, high labor intensity, large errors, and low processing accuracy. Therefore, it is necessary to design effective tooling and auxiliary fixtures. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned shortcomings by providing a multi-hole elastic punch device that facilitates efficient processing of multiple multi-hole workpieces and improves processing accuracy. It is suitable for on-site processing of multi-hole positioning drill holes.

[0004] The technical solution of this utility model is: a multi-hole elastic punching device, including a pressure plate. The number and position of the positioning holes to be processed are determined on the pressure plate according to the number and position of the holes on the workpiece plate. The positioning holes are countersunk holes with threads. There is a through hole at the bottom of the positioning hole through the pressure plate for the alloy punch to pass through. The piston positioning plate is installed in the lower end of the spring positioning sleeve. The spring is placed in the spring positioning sleeve. The spring positioning sleeve is screwed into the positioning hole. Then, the alloy punch, which is welded to the positioning plate on the piston, is placed on the spring. The device is locked and fixed by a hexagonal nut and a washer.

[0005] There are 3 positioning holes.

[0006] The advantages of this utility model are: 1. The main structural parts are composed of springs, impact components, and connecting components. Fixing the pressure plate (positioning plate) to the workpiece facilitates confirmation of the position of the hole to be processed, ensuring accurate positioning of each workpiece and guaranteeing processing precision. 2. This device is small in size, lightweight, has a reasonable structure, and can be reused. 3. It reduces the workload of workers and improves work efficiency.

[0007] The present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0008] Figure 1 This is a schematic diagram of the structure of this utility model.

[0009] Figure 2 This is a schematic diagram of the workpiece structure to be processed.

[0010] The parts in the diagram are named as follows: alloy punch 1, hexagonal nut 2, spring 3, spring positioning sleeve 4, piston positioning plate 5, pressure plate 6, gasket 7, positioning hole 8, piston upper positioning plate 9, through hole 10, weld 11, hole 12. Detailed Implementation

[0011] See Figure 1 , 2 A multi-hole elastic punching device includes a pressure plate 6. The number and position of the positioning holes 8 to be processed are determined on the pressure plate 6 according to the number and position of the holes 12 on the workpiece plate. The positioning holes 8 are countersunk holes with threads. At the bottom of the positioning holes 8, there is a through hole 10 through the pressure plate 6 for the alloy punch 1 to pass through. A piston positioning plate 5 is installed inside the lower end of a spring positioning sleeve 4, which serves to hold the spring. A spring 3 is placed inside the spring positioning sleeve 4, and the spring positioning sleeve 4 is screwed into the positioning hole 8. Then, the alloy punch 1, after being welded to the piston positioning plate 9, is placed on the spring 3. The device is locked and fixed by a hexagonal nut 2 and a washer 7. The above is a simple structure of one hole on the pressure plate 6. If there are multiple holes 12 on the workpiece plate (…),… Figure 2 If there are three holes 12, then the pressure plate 6 will have multiple corresponding holes. An alloy punch 1 is installed in each hole. In use, the pressure plate 6 is fixed to each workpiece, and holes are drilled one by one. Then, the holes 12 are machined. In use, the pressure plate 6 is fixed to the workpiece, and the alloy punch 1 is hammered with a hammer. The alloy punch 1 moves downward under pressure, and the tip of the alloy punch 1 impacts the part to be machined under pressure, thereby forming a positioning reference eye on the workpiece. Then, the hole is machined, and so on, to process the next workpiece, ensuring that the holes on each workpiece are accurately positioned.

[0012] Instructions for use: Apply this device to each workpiece to control the hole position error and ensure it meets the qualified product standard. Install pressure plates 6 on both sides of the workpiece to be processed (the part to be processed) according to the part size. This fixes the workpiece in place. Drill holes one by one to reduce processing deviations. Then remove the pressure plates 6 and place the next workpiece on it, and so on. This ensures consistent hole positions across all plates, eliminating the need to draw hole positions on the workpiece each time, resulting in high efficiency and precision. The multi-hole elastic punching device reduces deviations caused by manual positioning. Manual positioning deviations are generally around 0.1mm, while the device's various positioning methods can stabilize the positioning deviation within 0.03mm.

[0013] The above description is merely a specific embodiment of this utility model, and the various examples do not constitute a limitation on the substantive content of this utility model.
