Description

[0002] An automatic punching machine is a machine consisting of four interconnected parts that work together to complete the punching process. First, the material is moved to the scanning area of ​​the automatic punching machine's camera. After the camera scans the image, it processes it and sends a signal to the control unit. Upon receiving the signal, the control unit further processes and controls the transmission unit to move the punch along the X and Y axes of the plane. After the movement is complete, the pneumatic unit starts working, and the solenoid valve controls the cylinder to perform the punching action. The automatic punching machine prints the positioning hole; the entire process is seamless, fast, accurate, and highly efficient.

[0003] In the existing technology, most drilling machines do not have shock absorption function. Drilling machines are prone to vibration during long-term operation. If vibration occurs during the drilling of steel plates, it can easily lead to the hole being drilled off-center or crooked, resulting in non-standard or unqualified drilling.

[0004] Therefore, this utility model proposes a shock-absorbing base for drilling. Utility Model Content

[0027] This embodiment proposes a shock-absorbing base for drilling operations, such as... Figure 1 and Figure 2 As shown, it includes a base 1, a sliding plate 11 and a shock absorption mechanism 2. The two sides of the sliding plate 11 are slidably connected to the inner wall of the base 1, and the top of the sliding plate 11 is fixedly connected to a slide rail 12. This structure allows the sliding plate 11 to move only in the vertical direction, avoiding positioning errors caused by horizontal sway.

[0028] The shock absorption mechanism 2 is located at the bottom of the inner wall of the base 1. The shock absorption mechanism 2 includes a fixing plate 21 fixed to the bottom of the base 1. The fixing plate 21 is provided with a pair of U-bolts 22 and at least three layers of elastic metal sheets 23 are fixedly installed through the U-bolts 22. The elastic metal sheets 23 are arranged in an arc shape and stacked in sequence. The two ends of the elastic metal sheet at the top are provided with mounting parts 231 and are connected to the bottom of the sliding plate 11 through the mounting parts 231. The arc-shaped design causes the metal sheet to undergo gradual deformation when compressed. Combined with the stacked structure, it forms a multi-level buffer gradient, which can absorb high-frequency vibration energy.

[0029] Working principle: The drilling machine body is mounted on the sliding plate 11. When the drilling machine body vibrates, the vibration is transmitted to the lower part and then damped by the bow-shaped and stacked elastic metal sheets 23. The metal sheets undergo progressive elastic deformation, and the multi-layered elastic metal sheets 23 progressively bear the vibration, effectively absorbing the vertical impact energy. In addition, the damping mechanism 2 is easy to install. The elastic metal sheets 23 can be installed by U-bolts 22 and fixing plates 21. An anti-vibration mechanism 3 can also be provided on the side of the damping mechanism 2 to adapt to the use of the damping mechanism 2, further improving the anti-vibration performance and realizing the damping function to improve the overall damping performance and solve the drilling deviation problem of drilling machines without damping function.

[0030] In this embodiment, as Figure 2 As shown, the elastic metal sheet 23 is an arc-shaped corrugated plate, and the length of at least three layers of elastic metal sheets 23 decreases sequentially from top to bottom. This design makes the stress evenly distributed along the length of the metal sheet, avoids local stress concentration, and improves service life.

[0031] In this embodiment, as Figure 2 As shown, the shock absorption mechanism 2 also includes a U-shaped clamp, which is sleeved on the outer edge of the multi-layer elastic metal sheet 23 and fixedly connected by clamp bolts 24, effectively suppressing the lateral displacement of the metal sheet and reducing abnormal noise.

[0032] In this embodiment, as Figure 3As shown, a seismic damping mechanism 3 is symmetrically arranged on both sides of the inner wall of the base 1. The seismic damping mechanism 3 includes a seismic base plate 31 fixed to the bottom of the base 1, two sleeves 32 vertically fixed to the top two sides of the seismic base plate 31, and a top plate 33 fixed to the bottom of the sliding plate 11. Sliding columns 34 coaxially sleeved with the sleeves 32 are fixed on both sides of the bottom of the top plate 33. A central spring 35 is provided between the center of the seismic base plate 31 and the center of the bottom of the top plate 33. This mechanism and the shock absorption mechanism 2 form a cooperative damping system: small amplitude vibrations are absorbed by the metal sheet, and large amplitude impacts are buffered twice by the compression of the central spring 35 by the sliding column 34, thereby improving the overall seismic efficiency.

[0033] In this embodiment, the inner wall of the sleeve 32 is provided with a graphite lubricating layer, and the diameter of the sliding column 34 is clearance-fitted with the inner diameter of the sleeve 32, completely isolating metal debris and oil stains, thereby extending the life of the spring.

[0034] In this embodiment, a corrugated dust cover 36 is fitted around the central spring 35, and the two ends of the dust cover 36 are fixed to the anti-vibration base plate 31 and the top plate 33, respectively.

[0035] In this embodiment, a pulley 13 is slidably connected inside the slide rail 12, and a shelf 14 is fixedly connected to the top of the pulley 13. A drilling machine body is provided on the top of the shelf 14. Support plates are fixedly connected to both sides of the upper surface of the base 1, and a clamping mechanism 4 is fixedly connected to the support plates.

[0036] In this embodiment, as Figure 4 As shown, the clamping mechanism 4 includes a U-shaped groove 41, a threaded sleeve 42 at the top of the U-shaped groove 41 and a threaded rod 43 connected through it by threads, a clamping plate 44 at the bottom of the threaded rod 43, and a rotating handle 45 at the top of the threaded rod 43 to achieve quick clamping of the workpiece.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
