[0031] Medical aesthetics refers to the use of drugs, surgery, medical devices, and other invasive or irreversible medical techniques to repair and reshape a person's appearance and various parts of the body. As a safe and scientific cosmetic procedure, medical aesthetics has broad development prospects and a wide audience. Medical aesthetic equipment includes beauty instruments, facial steamers, etc. These devices mostly use plastic shells, while some use stainless steel or other metals, with perforated processing depending on the specific needs of the equipment.

[0032] In related technologies, a ring and spring are installed on the electric actuator, and a protective cover is installed at the bottom of the spring. When punching is required on the housing, the telescopic motor pushes the drill rod downwards, and the protective cover can wrap around the drill rod to prevent debris from splashing out during punching from accidentally injuring workers. However, in the existing device, the protective cover can affect the observation of the drill rod to some extent, requiring workers to bend over to check or remove the protective cover, which is quite cumbersome.

[0033] To address some of the problems in related technologies, this application provides a chassis housing punching device. When punching a chassis housing, the housing is first placed on the workbench 11 and clamped and fixed using the clamping mechanism 12. Then, the hydraulic rod 13 pushes the drill rod 14 downwards, simultaneously moving the ring 21 downwards. Through the spring 22 and the top plate 23, the protective cover 24 moves downwards as well. After the protective cover 24 contacts the housing, it protects the area around the drill rod 14. The hydraulic rod 13 continues to push the drill rod 14 for punching, while the ring 21 compresses the spring 22. The protective cover 24 then presses firmly against the housing. After punching is complete, the hydraulic rod 13 retracts. At this point, the drill rod 14 can be inserted into its original position. The top plate 23 is pushed upward, which in turn moves the adjusting rod 25 upward and squeezes the locking block 28. Due to the inclined design of the locking block 28, it retracts into the housing 26 after being squeezed, and compresses the second spring 27 until the locking block 28 aligns with the groove on the adjusting rod 25. Then, the second spring 27 rebounds and pushes the locking block 28 to engage with it. As the adjusting rod 25 rises, the locking block 28 repeats the above action until the protective cover 24 rises above the drill rod 14. At this point, the locking block 28 on the top plate 23 is released from its engagement with the groove on the adjusting rod 25, which can restrict the position of the protective cover 24. After inspection, the lever 29 is pushed to retract the locking block 28, causing the locking block 28 to disengage from the adjusting rod 25. Then, the first spring 22 rebounds and pushes the top plate 23 downward, thus restoring the position of the protective cover 24.

[0034] This application is described below with reference to the accompanying drawings and specific embodiments:

[0035] Combination Figures 1-4 This application provides a chassis shell punching device, including: a workbench 11 with a clamping mechanism 12 disposed on its inner side; a hydraulic rod 13 disposed on the top of the workbench 11; a drill rod 14 disposed on the bottom of the hydraulic rod 13; a lifting assembly 2 disposed on the workbench 11, the lifting assembly 2 including: a ring 21 fixedly sleeved on the outer side wall of the hydraulic rod 13; a spring 22 disposed on the bottom of the ring 21; a top plate 23 sleeved on the outer side wall of the hydraulic rod 13 and connected to the bottom of the spring 22; a protective cover 24 disposed on the bottom of the top plate 23; an adjusting rod 25 with its bottom end penetrating through the top of the workbench 11 and connected to the top plate 23; a housing 26 disposed on the top of the workbench 11; a spring 27 disposed inside the housing 26; a locking block 28 with one end inserted into the inside of the housing 26 and connected to the spring 27; and a lever 29 with its bottom end inserted into the inside of the housing 26 and connected to the locking block 28.

[0036] When punching holes in the chassis housing, first place the housing on the workbench 11 and clamp it in place using the clamping mechanism 12. Then, use the hydraulic rod 13 to push the drill rod 14 downward, simultaneously moving the ring 21 downward. Through the spring 22 and the top plate 23, the protective cover 24 moves downward as well. After the protective cover 24 contacts the housing, it can protect the area around the drill rod 14. At this time, the hydraulic rod 13 continues to push the drill rod 14 to punch, while the ring 21 pushes the spring 22 to compress. The protective cover 24 can then press the housing firmly. After punching is completed, the hydraulic rod 13 retracts. To insert the drill rod 14, the top plate 23 can be pushed upward, simultaneously moving the adjustment... The lever 25 moves upward and presses against the locking block 28. Due to the inclined design of the locking block 28, it retracts into the housing 26 after being pressed, and compresses the second spring 27 until the locking block 28 aligns with the groove on the adjusting rod 25. Then, the second spring 27 rebounds and pushes the locking block 28 to engage with it. As the adjusting rod 25 rises, the locking block 28 repeats the above action until the protective cover 24 rises above the drill rod 14. At this time, the locking block 28 is released from the top plate 23, which can restrict the position of the protective cover 24 by engaging with the groove on the adjusting rod 25. After inspection, the lever 29 is pushed to retract the locking block 28, so that the locking block 28 is disengaged from the adjusting rod 25. Then, the first spring 22 rebounds and pushes the top plate 23 downward, thus restoring the position of the protective cover 24.

[0037] In some embodiments, the lifting assembly 2 further includes push plates 231 symmetrically arranged on both sides of the top plate 23.

[0038] When in use, the design of the push plate 231 makes it easy to grip and control the top plate 23 to move upward.

[0039] In some embodiments, the lifting assembly 2 further includes a rubber strip 241 disposed at the bottom of the protective cover 24.

[0040] The soft material of the rubber strip 241 prevents scratches on the housing when in contact with it.

[0041] In some embodiments, the lifting assembly 2 further includes an arc-shaped block 251 disposed on the top of the adjusting rod 25.

[0042] When in use, the curved block 251 has no sharp edges, resulting in less friction when the squeeze block 28 retracts.

[0043] In some embodiments, the lifting assembly 2 further includes a sponge pad 291 disposed on the inner side of the lever 29.

[0044] The design of the sponge pad 291 during use makes the touchpad 29 more comfortable when it comes into contact with your fingers.

[0045] In some embodiments, the lifting assembly 2 further includes: a limiting rod 271 with one end penetrating through the outer side wall of the housing 26 and passing through the spring 27 to be connected to the locking block 28.

[0046] The design of the limiting rod 271 during use ensures that the spring 27 is prevented from bending when compressed, thus better protecting the spring 27.

[0047] In some embodiments, the protective cover 24 is provided with a connecting assembly 3. The connecting assembly 3 includes: a slot 31 opened on the top of the top plate 23; a groove 32 opened on the top of the protective cover 24; a crossbar 33 disposed inside the groove 32; a moving block 34 slidably disposed on the outer side wall of the crossbar 33; and a spring 35 disposed on the outer side of the crossbar 33 and connected to the moving block 34 at both ends.

[0048] When using the protective cover 24, if it is necessary to remove it to clean the debris adsorbed on the inner wall, push the top plate 23 so that the locking block 28 connects with the adjusting rod 25, which can restrict the downward movement of the top plate 23. Then pull the protective cover 24. At this time, the moving block 34 is squeezed and slides on the crossbar 33, approaching the compression spring 35, until it is disengaged from the slot 31. After cleaning, simply align the top of the protective cover 24 with the top plate 23 and insert the moving block 34 into the slot 31 to complete the installation of the protective cover 24.

[0049] In some embodiments, the connecting components 3 are arranged symmetrically in pairs in four groups.

[0050] When in use, the design of four sets of connecting components can connect the four corners of the top of the protective cover 24, thus making it more stable.
