Description

Technical Field

[0001] This utility model relates to an engraving device, specifically, to a pneumatic percussion engraving device. Background Technology

[0002] Carving refers to the cutting or carving of wood, stone, or other materials into desired shapes. Tools used for this purpose include knives, chisels, round chisels, cones, flat axes, and hammers. In ancient times, craftsmen typically held a chisel in one hand and a mallet in the other, using the mallet to strike the chisel into the wood or stone to carve. With the development of technology, carving techniques and tools have become more advanced. Various carving devices exist today, among which pneumatic carving devices are compact, inexpensive, easy to use, fast, portable, convenient, provide permanent markings, and are flexible and easy to operate. Powered by air, they are clean and pollution-free, and operate at high speeds. Impact-type engraving is vibration-free and noiseless, and is widely used for engraving on the surfaces of almost all hard materials such as metal, porcelain, glass, plastic, marble, and wood. Pneumatic engraving devices use air pressure to move a striking needle to impact the surface of the object to be engraved. During the impact of the striking needle on part of the object, debris is generated and accumulates on the surface. As the debris accumulates on the surface, it affects the worker's ability to engrave subsequent objects. Therefore, the worker needs to clean the debris from time to time during the engraving process, which prolongs the engraving time and reduces the worker's engraving efficiency. In view of this, we propose a pneumatic impact engraving device. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figure 1 - Figure 5 as well as Figure 7As shown, one of the objectives of this embodiment is to provide a pneumatic percussion engraving device, including a mounting base 1. A mounting shell 11 is threadedly sealed to the outside of the mounting base 1. An installation cavity is formed inside the mounting base 1 and communicates with the interior of the mounting shell 11. A solenoid valve is fixedly installed at the end of the mounting base 1 away from the mounting shell 11, and the solenoid valve communicates with the installation cavity. An air pipe is fixedly installed on one side of the solenoid valve, connecting the air pipe to an external air source. A percussion mechanism 2 is installed inside the mounting shell 11. The external air source injects compressed air into the interior of the installation cavity through the air pipe and the solenoid valve to drive the percussion mechanism. The engraving device 2 includes a movable seat 21 located at the end of the mounting base 1 away from the solenoid valve. The movable seat 21 is slidably disposed inside the mounting housing 11. A positioning seat 23 is disposed inside the mounting housing 11 away from the mounting base 1. A limit groove is formed on the surface of the positioning seat 23 away from the compression spring 22. A limit ring is fixedly disposed on the inner wall of the mounting housing 11 near the limit groove. The limit ring is located inside the limit groove. The positioning seat 23 is fixed inside the mounting housing 11 by the limit ring and the limit groove to prevent the positioning seat 23 from shifting during the use of the engraving device.

[0025] A compression spring 22 is provided between the movable seat 21 and the positioning seat 23. When the compression spring 22 is compressed, it relaxes and pushes the movable seat 21 and the positioning seat 23 closer to the mounting seat 1 and the mounting shell 11, respectively. A sealing ring is provided at the contact position between the movable seat 21 and the mounting seat 1. A striking needle 24 is provided inside the movable seat 21. One end of the striking needle 24 passes through the compression spring 22 and the positioning seat 23 and extends outward. The striking needle 24 and the movable seat 21 are sealed to prevent gas from escaping from the gap between them. The striking needle 24 is fixedly installed to the movable seat 21. When the striking needle 24 is damaged due to impact, the operator rotates the mounting shell 11 around the mounting seat 1 to separate it from the mounting seat 1. Then, the operator removes the movable seat 21 and the striking needle 24 from the inside of the mounting shell 11 and replaces the damaged striking needle 24. The operator then reinstalls the replaced striking needle 24 and the movable seat 21 back into the mounting shell 11. Inside, there is a gap between the striking pin 24 and the inner wall of the mounting cavity. Air inside the mounting cavity blows through the gap onto the surface of the movable seat 21 near the mounting seat 1. The blown air pushes the movable seat 21 to move. An external air source injects compressed air into the interior of the mounting cavity through an air pipe and a solenoid valve, increasing the pressure inside the mounting cavity. Subsequently, the increased pressure of the gas inside the mounting cavity pushes the movable seat 21 to move closer to the positioning seat 23. The moving movable seat 21 drives the striking pin 24 to move and impact the surface of the object for engraving. During the movement of the movable seat 21, the compression spring 22 is further compressed. When the compressed air inside the mounting cavity enters the interior of the mounting shell 11, the pressure inside the mounting cavity decreases. When the thrust of the gas inside the mounting cavity on the movable seat 21 is less than the thrust of the compression spring 22, the compression spring 22, which is in a compressed state, relaxes and drives the movable seat 21 to move away from the positioning seat 23. The moving movable seat 21 drives the striking pin 24 to move and reset so as to facilitate subsequent impact engraving.

[0026] An air outlet mechanism 3 is provided inside the mounting housing 11. The air outlet mechanism 3 is used to blow the air inside the mounting housing 11 onto the engraved area of ​​the object surface. The air outlet mechanism 3 includes several annularly arranged front air outlets 31 that are opened on one side of the mounting housing 11 and pass through the mounting housing 11. The end of the mounting housing 11 away from the mounting base 1 is a slope, and the end of the front air outlet 31 away from the mounting base 1 is located on the slope. When the air in the mounting cavity enters the interior of the mounting housing 11, the gas inside the mounting housing 11 is blown out through the front air outlets 31. The blown gas blows onto the surface of the object and blows away the debris accumulated on the surface of the object, so that the staff does not need to clean the debris, shortens the time required for the object to be engraved, and improves the efficiency of the staff in engraving the object.

[0027] In summary, the workflow of this solution is as follows: The air pipe is connected to an external air source. The external air source injects compressed air into the mounting cavity through the air pipe and solenoid valve. Subsequently, the compressed gas pushes the movable seat 21 to move closer to the positioning seat 23. During the movement, the movable seat 21 drives the striking needle 24 to move and impact the object surface for engraving. When the movable seat 21 separates from the mounting seat 1, the air inside the mounting cavity enters the mounting shell 11. The gas inside the mounting shell 11 is blown out through the front air outlet 31. The blown gas blows onto the object surface and blows away the debris accumulated on the object surface. At the same time, the pressure inside the mounting cavity decreases, and the compression spring 22, which is in a compressed state, relaxes and drives the movable seat 21 and the striking needle 24 to move and reset in order to facilitate subsequent impact engraving.

[0028] Example 2

[0029] Based on Example 1, the air outlet mechanism 3 is improved, with reference to... Figures 3-7 An air regulating component is installed inside the mounting housing 11 to adjust the air outlet position. This component is part of the air outlet mechanism 3. The air regulating component includes an inner ring 33 rotatably mounted inside the mounting housing 11. Several front sealing plates 34 are fixedly arranged in a ring on the side of the inner ring 33 near the front air outlet 31, with the number and position of the front sealing plates 34 corresponding to the number of front air outlets 31. Several side sealing plates 35 are fixedly arranged in a ring on the side of the inner ring 33 away from the front sealing plates 34. Several side air outlets 32 penetrating the mounting housing 11 are arranged in a ring on the side wall of the mounting housing 11 near the side sealing plates 35, with the number and position of the side sealing plates 35 corresponding to the number of side air outlets 32. Two sliding grooves 38 penetrating the mounting housing 11 are symmetrically opened on the side wall of the mounting housing 11 near the inner ring 33. Two sliders 36 are symmetrically fixedly arranged on the inner ring 33 near the sliding grooves 38, and the sliders 36 slide through the sliding grooves 38. 8. An outer ring 37 is fixedly installed. When the operator does not need the air to be blown out of the front air outlet 31, the operator holds and rotates the outer ring 37, causing the outer ring 37 to rotate around the mounting shell 11. The rotating outer ring 37 drives the inner ring 33 to rotate through the slider 36. During the rotation, the inner ring 33 drives the front sealing plate 34 and the side sealing plate 35 to rotate. During the rotation of the front sealing plate 34 and the side sealing plate 35, the side of the front sealing plate 34 and the side sealing plate 35 close to the mounting shell 11 slides into contact with the inner wall of the mounting shell 11. There is a gap between the side of the front sealing plate 34 close to the positioning seat 23 and the positioning seat 23. The rotating front sealing plate 34 seals the front air outlet 31. At the same time, the rotating side sealing plate 35 separates from the side air outlet 32. The inside of the mounting shell 11 is connected to the outside through the side air outlet 32, so that the air inside the mounting shell 11 is discharged through the side air outlet 32, thereby changing the discharge direction of the air inside the mounting shell 11.

[0030] When the operator does not need air to be blown out of the front air outlet 31, the operator holds and rotates the outer ring 37. The rotating outer ring 37 drives the front sealing plate 34 and the side sealing plate 35 to rotate through the slider 36 and the inner ring 33. The front sealing plate 34 seals the front air outlet 31 and separates the side sealing plate 35 from the side air outlet 32, allowing the air inside the mounting shell 11 to be discharged through the side air outlet 32. By changing the direction of exhaust, this device can be applied to different scenarios. For example, when carving dry items, the gas is discharged towards the carved item to achieve the effect of blowing away dust. When carving items with water on the surface, such as carving jade, if the gas is blown on the carved object, it will affect the liquid on the surface of the item. In this case, the direction of exhaust is changed to avoid blowing the gas on the object, so that the jade can be carved normally.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
