Description

Technical Field

[0001] The utility model relates to the technical field of plate processing, in particular to a limiting device for punching metal plates of a power distribution cabinet. Background Art

[0002] In the distribution cabinet manufacturing industry, punching of metal plates is a crucial process step. In the traditional punching process, due to the lack of effective limiting devices, operators often find it difficult to accurately control the position and height of the drill bit, resulting in low punching accuracy and even problems such as misalignment and deflection. This not only affects the overall quality and aesthetics of the distribution cabinet, but may also pose a potential threat to its electrical performance and safety. To address this problem, some limiting devices have appeared on the market that attempt to solve the problem of punching accuracy. However, these devices often have problems such as complex structure, inconvenient adjustment, and insufficient stability. For example, some limiting devices use complex mechanical structures to achieve position adjustment, which not only increases the difficulty of operation, but is also prone to failure after long-term use. In addition, some devices also have limitations in height adjustment and cannot adapt to the punching needs of metal plates of different sizes and thicknesses. Utility Model Content

[0003] In order to solve the above problems, the present invention proposes a limiting device for punching holes in a metal plate of a power distribution cabinet, so as to more accurately solve the problems raised in the above background technology.

[0004] The utility model is achieved through the following technical solutions:

[0005] The utility model proposes a limiting device for punching metal plates in a distribution cabinet, comprising a workbench, a support frame installed on the top of the workbench, a sliding plate 1 with adjustable position provided on the top of the support frame, a sliding plate 2 with adjustable position provided on the top of the sliding plate 1, a height-adjustable height-adjusting part provided on the end of the sliding plate 2, a detachable limiting cylinder provided on the top of the height-adjusting part, the size of the limiting cylinder being adapted to the size of the drill bit, a connecting plate 1 provided on the bottom of the support frame at a sliding plate 1, a connecting plate 2 provided on the bottom of the sliding plate 1 at a sliding plate 2, a tensioning part provided on both the connecting plate 1 and the connecting plate 2, and the tensioning part being used to tighten the sliding plate 1 and the sliding plate 2.

[0018] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0019] Example

[0020] like Figure 1-Figure 3As shown, an embodiment of the present invention proposes a limiting device for punching metal plates in a distribution cabinet, the structure of which includes a stable workbench 1. A support frame 2 is installed on the top of the workbench 1, and the support frame 2 is used to provide structural support. On the top of the support frame 2, a position-adjustable sliding plate 1 3 is provided, which means that the sliding plate 1 3 can be moved in a certain direction on the support frame 2 to adapt to different work requirements. Furthermore, on the top of the sliding plate 1 3, a position-adjustable sliding plate 2 4 is provided, and the sliding plate 2 4 can also be moved on the sliding plate 1 3, providing a more precise position adjustment capability. The end of the sliding plate 2 4 is equipped with a height-adjustable height adjustment member 5 for adjusting the height to adapt to metal plates of different sizes. A detachable limiting cylinder 9 is installed on the top of the height adjustment member 5. The size of the limiting cylinder 9 is adapted to the size of the drill bit and is used to accurately limit the position of the drill bit. In order to stabilize the sliding plate 1 3 and the sliding plate 2 4, a connecting plate 1 6 is provided at the bottom of the support frame 2 at the sliding plate 1 3, and a connecting plate 2 7 is provided at the bottom of the sliding plate 1 3 at the sliding plate 2 4. Both connecting plates are equipped with a tensioning part 8, which tensions the sliding plate 1 3 and the sliding plate 2 4 through its elastic or mechanical action to ensure their stability during work. Through the above structure, the drill bit is accurately limited during the punching process of the metal plate of the distribution cabinet, thereby improving the punching accuracy and efficiency.

[0021] In the present invention, the tensioning portion 8 is specifically implemented by installing a return spring 83 at the bottom of connecting plate 1 6 or connecting plate 2 7. The bottom of return spring 83 is connected to a connecting plate 82, and a pull rod 81 is mounted on the top of connecting plate 82. The end of pull rod 81 is connected to the bottom of sliding plate 1 3 or sliding plate 2 4. When the sliding plate is moved into position, the return spring 83, through its elastic force, tightens the sliding plate through pull rod 81, ensuring that the sliding plate is not easily moved by external forces. The design of the tensioning portion 8 effectively improves the stability of the sliding plate and ensures the accuracy of the limit device during operation.

[0022] In the present invention, a T-block 61 is mounted on the top of the connecting plate 6, while a slide groove 21 is provided on the top of the support frame 2, which is compatible with the T-block 61 and allows the T-block 61 to slide within the slide groove 21. Similarly, a T-block 71 is mounted on the top of the connecting plate 7, while a slide groove 31 is provided on the top of the sliding plate 3, which is compatible with the T-block 71 and allows the T-block 71 to slide within the slide groove 31. This coordination of the T-block and the slide groove ensures both smooth and stable sliding. The coordination of the T-block and the slide groove allows the sliding plate to slide stably on the support frame and the other sliding plate, thereby improving the flexibility of the limiting device.

[0023] In the present invention, the height adjustment member 5 is specifically implemented by mounting a connecting ring 1 51 on the end of the sliding plate 2 4 . A height-adjustable connecting ring 2 52 is mounted on top of the connecting ring 1 51 . A stopper 9 is mounted on top of the connecting ring 2 52 . To adjust the height of the connecting ring 2 52 , an adjustment member 54 is mounted on one side of the connecting ring 1 51 . This adjustment member 54 allows for convenient adjustment of the height of the connecting ring 2 52 , and consequently, the height of the stopper 9 , to accommodate metal plates of varying sizes.

[0024] In the present invention, the specific implementation of the adjustment member 54 includes installing a connecting block 541 on one side of the connecting ring 2 52, and the top of the connecting block 541 is rotatably connected to a threaded sleeve 542 through a bearing. A threaded rod 543 is threadedly connected to the inner wall of the threaded sleeve 542, and the bottom of the threaded rod 543 is connected to the sliding plate 2 4. In order to ensure the stability of the adjustment, a guide rod 544 is also connected to the connecting block 541, and the bottom of the guide rod 544 is also connected to the sliding plate 2 4. When the threaded sleeve 542 is rotated, the threaded rod 543 will rise or fall due to the action of the thread, thereby driving the connecting ring 2 52 and the limiting cylinder 9 to rise or fall. By rotating the threaded sleeve 542, the height of the limiting cylinder 9 can be conveniently adjusted, and the adjustment process is stable and reliable.

[0025] In the present invention, a hollow threaded seat 53 is mounted on the top of the second connecting ring 52, and a hollow threaded ring 91 that matches the hollow threaded seat 53 is mounted on the bottom of the limiting cylinder 9. When the limiting cylinder 9 needs to be installed on the second connecting ring 52, it is only necessary to insert the hollow threaded ring 91 into the hollow threaded seat 53 and rotate the limiting cylinder 9 so that the hollow threaded ring 91 is threadedly connected to the hollow threaded seat 53. The threaded connection between the hollow threaded seat 53 and the hollow threaded ring 91 realizes a detachable connection between the limiting cylinder 9 and the second connecting ring 52, which facilitates the replacement and maintenance of the limiting cylinder 9.
