This will place more efficient and precise demands on the process equipment and functional components used for small parts, and the demand for humanized process equipment will increase daily. Traditionally, the rail vehicle industry relies on manual operation, sometimes using templates and tooling, but this is usually purely manual, resulting in low efficiency, high labor costs, and high labor intensity. Incorrect assembly of workpieces frequently occurs. Furthermore, the water-based pens used for manual marking have a certain impact on welding quality, and the lines drawn with these pens are often ground away during pre-welding grinding, affecting the accuracy of component assembly.

[0041] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0042] See Figures 1 to 3 As shown;

[0043] This embodiment provides a CNC scribing device for aluminum alloy parts, the scribing device comprising:

[0044] Device housing assembly 1;

[0045] A pneumatic etching assembly 3 is disposed at the front end of the device housing assembly 1; and

[0046] Hydraulic component 4 is located at the tail end of device housing assembly 1;

[0047] The marking device is connected to an external pneumatic control device 5 via a compressed air pipeline, so that compressed air is delivered into the device housing assembly 1 through the external pneumatic control device 5 to drive the pneumatic marking needle assembly 3 at the front end to move.

[0048] The hydraulic component 4 is connected to the hydraulic oil supply system through hydraulic lines, and the internal piston 401 is driven by hydraulic pressure to move to cushion the device housing component 1.

[0049] Specifically, this embodiment discloses a CNC scribing device for aluminum alloy parts. Its exterior is a housing assembly 1, with a pneumatic scribing needle assembly 3 integrated at the front end and a hydraulic assembly 4 integrated at the rear end. In this embodiment, compressed air is provided to the pneumatic scribing needle assembly 3 by an external pneumatic control device 5, thereby driving the pneumatic scribing needle assembly 3 to vibrate at high frequency and scribing lines on the aluminum alloy part. This device is suitable for CNC equipment. The dimensions and trajectory to be scribed can be pre-programmed, and then the device can be operated using a robotic arm or other mechanism to scribing lines on the aluminum alloy part using the pneumatic scribing needle assembly 3. Since the needle of the pneumatic scribing needle assembly 3 is constantly in contact with the workpiece surface, it tends to move the housing during scribing. To provide a buffering effect, a hydraulic assembly 4 is provided at the rear end of the device in this embodiment. The hydraulic movement of the hydraulic assembly 4 provides a certain buffering effect.

[0050] Preferably, the device housing assembly 1 in this embodiment includes:

[0051] Outer tube 101 and inner tube 102, and piston cylinder 103 installed between inner tube 102 and outer tube 101;

[0052] The lower ends of the inner tube 102 and the piston cylinder 103 are connected by the base 2, and the lower end of the outer tube 101 is connected to the threaded seat 104. The outer tube 101 and the threaded seat 104 can slide along the outer wall of the piston cylinder 103.

[0053] First, this embodiment further defines the composition of the device housing assembly 1, which includes three parts: an outer tube 101, an inner tube 102, and a piston cylinder 103; the piston cylinder 103 forms the piston mounting space and hydraulic oil space of the hydraulic assembly 4. Second, the upper end of the outer tube 101 is configured as a compressed air channel 106 connected to the pneumatic engraving needle assembly 3, and the lower end is a movable end; third, the inner tube 102 and the piston cylinder 103 together form the hydraulic oil space of the hydraulic assembly.

[0054] In this embodiment, the outer tube 101 is connected to the pneumatic engraving and punching assembly 3, and one end protrudes to form a compressed air cylinder 105, and a compressed air channel 106 is formed inside the compressed air cylinder 105.

[0055] The pneumatic engraving and punching assembly 3 is integrated at the end of the compressed air cylinder 105. Compressed air supplied by the external pneumatic control device 5 flows from the compressed air channel 106 toward the pneumatic engraving and punching assembly 3 to drive the pneumatic engraving and punching assembly 3 to work.

[0056] Preferably, the pneumatic engraving and punching assembly 3 in this embodiment includes:

[0057] A cone 301 is installed at the end of the compressed air cylinder 105, and the end of the cone 301 is provided with a needle-carving channel 106.

[0058] A marking needle 302 is located inside the cone 301, and the tip of the marking needle 302 extends outward from the marking needle channel 106; and

[0059] A compression spring 303 is sleeved on the outside of the engraving needle 302;

[0060] A sealing seat 304 is installed at one end of the engraving needle 302 near the compressed air cylinder 105. The sealing seat 304 is recessed inward at the position where it mates with the compressed air channel 106 to form a groove 305. The groove 305 is used to receive compressed air and drive the engraving needle 302 to move through the compressed air.

[0061] During operation, compressed air supplied by the external pneumatic control device 5 enters the space of the groove 305, thereby driving the sealing seat 304 and the engraving needle 302 to move synchronously. When the sealing seat 304 leaves the area, the sealing state is released, allowing the compressed air to leak and eventually be discharged to the outside through the channel of the engraving needle 302. Finally, the engraving needle 302 is reset under the action of the compression spring 303 to continue the next engraving operation.

[0062] Preferably, in this embodiment, the space between the upper end of the piston cylinder 103 and the outer tube 101 is a compressed air receiving chamber. The compressed air pipe of the external pneumatic control device 5 is connected to the compressed air receiving chamber, and the compressed air receiving chamber is connected to the compressed air channel 106.

[0063] Preferably, the hydraulic component 4 in this embodiment includes: a piston 401 with one end located inside the piston cylinder 103, a return spring 403 provided between the piston 401 and the base 2; a shock-absorbing head 404 provided at one end of the piston 401 extending into the compressed air receiving chamber, and a silencer sleeve 405 provided at the position where the shock-absorbing head 404 cooperates with the upper end of the outer tube 101; the piston cylinder 103 has an interface 403 that communicates with the hydraulic pipeline of an external hydraulic oil supply system, so as to deliver hydraulic oil into the piston cylinder 103 through the external hydraulic oil supply system and drive the piston 401 to move.

[0064] In order to provide buffering and noise reduction, an embedding groove 107 is formed at the position where the outer tube 101 and the noise reduction sleeve 405 meet, and the shape and size of the embedding groove 107 match the noise reduction sleeve 405.

[0065] When the outer tube 101 moves, the sound-absorbing sleeve 405 impacts the embedded groove 107.

[0066] During operation, the hydraulic components primarily function as a buffer. Hydraulic oil within the piston cylinder 103 guides the piston 401 to move. Simultaneously, in this embodiment, the piston head at one end of the piston 401 inside the piston cylinder 103 has a small hole. This hole guides the hydraulic oil on one side to the other, and together with the aid of the return spring 402, acts on the piston 401, allowing it to reciprocate. Since the engraving needle is constantly in contact with the aluminum alloy workpiece, the outer tube 101 moves in the opposite direction during engraving. To reduce noise and provide cushioning, the end of the piston 401 is equipped with a shock-absorbing head 404 and a noise-reducing sleeve 405.

[0067] In the above technical solution, the CNC scribing device for aluminum alloy parts provided by this utility model has the following beneficial effects:

[0068] The scribing device of this invention is based on CNC scribing technology, replacing the traditional manual operation. The scribing lines have a certain depth on the surface of the workpiece and will not be removed during grinding.

[0069] This utility model's marking device is applicable to the rail vehicle industry. Welding workshops no longer need small component riveters. CNC machine tools can directly mark the position, shape, and number of each component on large components. Welders can then assemble and spot weld according to the numbers. This not only frees up labor but also significantly improves manufacturing precision, reduces labor intensity, and thus improves product quality. It can effectively avoid the phenomenon of manual misalignment and omission of components.
