Description

Technical Field

[0001] This utility model relates to the field of drilling technology, and in particular to an automatic drilling device for metal products. Background Technology

[0002] Drilling is often required in metal processing. A patent application (CN202023340405.X) proposes a vertical drilling machine with a protective mechanism; however, the protective cover has certain design limitations in practical use: when the length of the workpiece exceeds the longitudinal dimension of the cover, the structure of the cover makes it difficult for the operator to securely fix the extra-long metal workpiece on the worktable. Removing the protective cover solves the workpiece fixation problem, but the high-speed flying metal debris generated during drilling lacks effective restraint, which not only pollutes the working environment but may also threaten the safety of the operator. Therefore, improvements are needed. Utility Model Content

[0003] The main objective of this invention is to provide an automatic punching device for metal products, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An automatic drilling device for metal products includes a support frame with a lifting platform mounted on it. A enclosure frame is fixedly fitted onto the lifting platform. The enclosure frame consists of a first enclosure plate, a second enclosure plate, and a connecting plate. There are two second enclosure plates and three connecting plates. The connecting plates connect the first enclosure plate and two second enclosure plates together, and simultaneously connect two second enclosure plates together. Several lifting enclosure plates are movably mounted on the connecting plates. A fixing component is fixedly mounted on the outer end of each lifting enclosure plate. The fixing component consists of a U-shaped frame, a base rod, an annular plate, a spring, and a pull plate. The base rod is slidably mounted on the U-shaped frame, the annular plate is fixedly fitted onto the base rod, the spring is also fitted onto the base rod, and the pull plate is fixedly mounted on the outer end of the base rod.

[0006] Preferably, a base is fixedly installed at the lower end of the support frame, and a drilling assembly is fixedly installed at the upper end of the support frame.

[0007] Preferably, the first and second enclosure panels on the enclosure frame are both fixedly installed on the side end face of the lifting platform, the connecting plate is located on the side of the lifting platform, the connecting plate is fixedly connected to the first and second enclosure panels, and the connecting plate has a plurality of first holes.

[0008] Preferably, the lifting enclosure has a connecting groove, and the lifting enclosure is movably fitted onto the connecting plate through the connecting groove.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, an automatic drilling device for metal products includes a support frame 1, a lifting platform 2 mounted on the support frame 1, and a retaining frame 3 fixedly fitted on the lifting platform 2. The retaining frame 3 consists of a first retaining plate 8, a second retaining plate 9, and a connecting plate 10. There are two second retaining plates 9 and three connecting plates 10. The connecting plates 10 connect the first retaining plate 8 and the two second retaining plates 9 together, and simultaneously connect the two second retaining plates 9 together. Several lifting retaining plates 4 are movably mounted on the connecting plates 10. A fixing component 5 is fixedly mounted on the outer end of the lifting retaining plate 4. The fixing component 5 consists of a U-shaped frame 14, a base rod 16, an annular plate 17, and a spring 18. The system consists of a pull plate 19, a base rod 16 slidably mounted on a U-shaped frame 14, an annular plate 17 fixedly sleeved on the base rod 16, a spring 18 also sleeved on the base rod 16, a pull plate 19 fixedly mounted on the outer end of the base rod 16, a base 6 fixedly mounted on the lower end of the support frame 1, and a drilling assembly 7 fixedly mounted on the upper end of the support frame 1. When drilling holes in metal products, the metal products can be fixed on the upper end of the lifting platform 2, and then the equipment can be started, causing the lifting platform 2 to move upward with the metal products, eventually bringing the metal products into contact with the high-speed rotating drill bit on the drilling assembly 7. At this point, a hole will be drilled in the metal products. When the length of the metal products is long, such as... Figure 1 When the partially raised enclosure 4 obstructs the metal products fixed on the lifting platform 2 in the state shown, the raised enclosure 4 that obstructs the metal products can be adjusted downwards. The method is to first use the fixing component 5 to release the fixing of the raised enclosure 4 and the enclosure frame 3, and then move the raised enclosure 4 downwards until the upper end of the raised enclosure 4 is flush with the upper end of the lifting platform 2. At this time, the raised enclosure 4 after being adjusted downwards will not affect the fixing of the longer metal products on the upper end of the lifting platform 2, while the remaining raised enclosure 4 that has not been adjusted downwards, together with the enclosure frame 3, can still block the debris generated by drilling.

[0021] Specifically, the first enclosure plate 8 and the second enclosure plate 9 on the enclosure frame 3 are both fixedly installed on the side end face of the lifting platform 2. The connecting plate 10 is located on the side of the lifting platform 2. The connecting plate 10 is fixedly connected to the first enclosure plate 8 and the second enclosure plate 9. The connecting plate 10 has several first holes 11. The lifting enclosure plate 4 has a connecting groove 12. The lifting enclosure plate 4 is movably fitted onto the connecting plate 10 through the connecting groove 12. The lifting enclosure plate 4 has a second hole 13. The second hole 13 passes through the inside and outside of the lifting enclosure plate 4. The second hole 13 is also connected to the connecting groove 12. After the lifting enclosure plate 4 is released from the fixing of the connecting plate 10 on the enclosure frame 3, the lifting enclosure plate 4 can slide up and down along the connecting plate 10 through the connecting groove 12.

[0022] Specifically, the U-shaped frame 14 on the fixing component 5 is fixedly installed on the outer end of the lifting enclosure 4. A third hole 15 is opened on one side wall of the U-shaped frame 14. The base rod 16 on the fixing component 5 is slidably installed in the third hole 15. The annular plate 17 and the spring 18 are both located inside the U-shaped frame 14, and the pull plate 19 is located outside the U-shaped frame 14. By pulling the pull plate 19, the base rod 16 slides outward, and the spring 18 is compressed. When the base rod 16 moves out of the first hole 11, the lifting enclosure 4 can move freely. When the lifting enclosure 4 moves as... Figure 1 In the state shown, after the pull plate 19 is released, the spring 18 rebounds and pushes the base rod 16 into the first hole 11 of the connecting plate 10. At this time, the lifting plate 4 is fixed on the connecting plate 10.

[0023] Finally, by setting up a protective cover consisting of a enclosure frame 3 and a lifting enclosure 4, the problem that the protective cover in the prior art cannot be adapted to ultra-long workpieces is solved. The lifting enclosure 4 can be flexibly adjusted up and down according to the length of the workpiece, and the workpiece can be firmly fixed without removing the protective cover. At the same time, it can also effectively block metal debris flying during drilling, ensuring operational safety. The fixing component 5 adopts a spring 18 sliding design, which makes adjustment more convenient, facilitates the fixing and release of the lifting enclosure 4, and facilitates the up and down movement and adjustment of the lifting enclosure 4, thereby improving work efficiency.

[0024] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
