[0018] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0019] Embodiment 1

[0020] As Figures 1-4 shown, the utility model provides a kind of technical scheme: a kind of pneumatic device for automobile parts production and processing, including pneumatic sander main body 1, the output end of pneumatic sander main body 1 side is fixedly connected with output shaft 2, and the one end of output shaft 2 is fixedly connected with mounting piece 3, the one side of this mounting piece 3 is connected with butt joint 4, and let polishing head 5 be preinstalled in the one end of mounting piece 3 under the help of butt joint 4, prepare for further reinforcement installation of polishing head 5 in the one side of mounting piece 3, and the one end of butt joint 4 is fixedly connected with polishing head 5, pneumatic sander main body 1 will drive output shaft 2 to rotate when starting, the rotation of output shaft 2 drives mounting piece 3 to rotate as a whole, when the insertion rod 7 on mounting piece 3 is connected with butt joint 4, mounting piece 3 will stably drive butt joint 4 and polishing head 5 to rotate, so that polishing head 5 is polished to automobile parts, and the outer surface of mounting piece 3 is connected with insertion rod 7, and the one end of insertion rod 7 is connected with butt joint 4, when butt joint 4 is connected and installed on the one side of mounting piece 3, butt joint 4 is positioned in mounting piece 3, improve the stability of polishing head 5 installation in the one side of mounting piece 3, the outer surface of this insertion rod 7 is fixedly connected with extension plate 8, spring 9 is sleeved on the surface of insertion rod 7 at the lower end of extension plate 8, the outer surface of mounting piece 3 is fixedly connected with blocking frame 10 in the position of insertion rod 7, and the blocking frame 10 is provided with passageway, by twisting the one end of insertion rod 7 and driving extension plate 8 to rotate, so that the orientation of extension plate 8 is matched with the orientation of the passageway of blocking frame 10, the movement of extension plate 8 is blocked by blocking frame 10, then spring 9 is rebounded outward, so that extension plate 8 is automatically pushed outward, so that insertion rod 7 is automatically disconnected with butt joint 4, then polishing head 5 can be directly pulled out to complete disassembly, simple and fast.

[0021] Embodiment 2

[0022] As Figures 1-4As shown, a positioning slider 6 is fixedly connected to the outer surface of the connector 4, and the positioning slider 6 is slidably connected to the mounting part 3. With the help of the positioning slider 6, the position of the insertion port on the connector 4 in the mounting part 3 is positioned, which facilitates the direct connection between the insertion rod 7 and the insertion port on the connector 4. A limiting ring 11 is fixedly connected to the outer surface of the insertion rod 7, and the limiting ring 11 is slidably embedded in the mounting part 3. The limiting ring 11 plays a role in limiting the movement of the insertion rod 7 on the mounting part 3, preventing the insertion rod 7 from moving excessively outward and detaching from the mounting part 3 due to the rebound of the spring 9. A cover 12 is threaded onto one end of the mounting part 3. When the insertion rod 7 is connected to the connector 4, the cover 12 is rotated relative to the mounting part 3, causing the cover 12 to move on the mounting part 3 to cover one end of the insertion rod 7, further hindering the outward movement of the insertion rod 7 and improving the stability of the connection between the insertion rod 7 and the connector 4. Anti-slip protrusions are fixedly connected to the outer surface of the cover 12. The anti-slip protrusions increase the friction of the outer surface of the cover 12, thereby effectively preventing slippage when the surface of the cover 12 is manually rotated.

[0023] Working principle:

[0024] like Figures 1-4 As shown, when using this utility model, if the grinding head 5 needs to be disassembled and replaced, the user first manually moves the cover 12 to rotate relative to the mounting part 3, moving it to one side of the mounting part 3, thus releasing the cover 12 from blocking one end of the insertion rod 7. Then, the user manually twists one end of the insertion rod 7, causing the extension plate 8 to rotate, so that the position of the extension plate 8 matches the position of the passage of the blocking frame 10, thus releasing the blocking frame 10 from obstructing the movement of the extension plate 8. Then, due to the outward rebound of the spring 9, the extension plate 8 is pushed outward. The movement of the extension plate 8 causes the insertion rod 7 to move, thereby automatically disengaging the insertion rod 7 from the connector 4. During this process, with the help of the limit ring 11, the insertion rod 7 is prevented from moving excessively after disengaging from the connector 4, maintaining the connection between the insertion rod 7 and the mounting part 3 for easy future use. After the insertion rod 7 is disengaged from the connector 4, the grinding head 5 can be pulled out directly to disengage the connector 4 from the mounting part 3, completing the disassembly. Then, by reversing the above steps, a new grinding head 5 can be installed and replaced.

[0025] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in other forms, and any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields with equivalent changes, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application without departing from the technical scheme of the present application still falls within the protection scope of the present application.
