[0002] In the automobile manufacturing industry, surface treatment of parts is one of the key steps to ensure the quality and performance of parts. In order to improve the corrosion resistance, wear resistance of parts or achieve a specific aesthetic effect, surface treatment such as spraying, electroplating or chemical treatment is often required. In these processes, the use of additives can significantly improve the treatment effect, such as enhancing the adhesion of the coating, adjusting the hardness of the electroplated layer or changing the microstructure of the chemical treatment layer. In the preparation process of additive auxiliary materials, grinding is an indispensable link, which aims to refine the raw materials to the required particle size to ensure their uniform distribution and efficient action in subsequent processing.

[0029] like Figures 1 to 4As shown in the figure, this embodiment provides a grinding device for surface treatment additives of automotive parts. This grinding device for surface treatment additives of automotive parts includes a grinding cylinder 1 with a discharge pipe at the bottom, a cylinder cover 11 with a feed inlet detachably installed on the top of the grinding cylinder 1, a lifting connecting plate 2 vertically movably installed inside the grinding cylinder 1, a rotating shaft 3 rotatably installed in the middle of the lifting connecting plate 2 through a bearing, a grinding seat 5 coaxial with the grinding head 4 fixedly connected to the bottom end of the rotating shaft 3, and a grinding cavity 52 opened at the top of the grinding seat 5.
[0030] A pipe frame 61 is welded to one side of the top of the lifting connecting plate 2. A rotating pipe 62 is inserted and fixed to one end of the pipe frame 61 near the rotating shaft 3. The bottom of the rotating pipe 62 is rotatably mounted on the top of the rotating shaft 3 via a bearing. A channel 35 communicating with the inside of the rotating pipe 62 is opened at the top of the rotating shaft 3. An air jet pipe 6 is welded to the outer wall of the rotating shaft 3 and directly opposite the outlet end of the rotating shaft 3. The air outlet end of the air jet pipe 6 is located inside the grinding chamber 52. A vertical connecting pipe 64 is inserted and installed at the center of the top of the cylinder cover 11. A high-pressure air pump 65 is installed on one side of the top of the cylinder cover 11. Furthermore, the outlet of the high-pressure air pump 65 is connected to the inlet of the top of the vertical connecting pipe 64 through a pipe. A metal hose 63 is installed between the outlet of the bottom of the vertical connecting pipe 64 and the inlet of the top of the rotating pipe 62. The airflow is finally sprayed out through the jet pipe 6 and sprayed into the interior of the grinding chamber 52, causing the raw material inside the grinding chamber 52 to be lifted or flow, which promotes the further uniform and comprehensive distribution of the raw material inside the grinding chamber 52, further improving the contact area between the raw material and the grinding head 4 at the same time, resulting in high grinding efficiency, and also helps to avoid material residue in the grinding chamber 52.
[0031] like Figures 1 to 3 As shown in the figure, in this embodiment, electric telescopic rods 22 are installed on both sides of the top of the cylinder cover 11, and the movable end of the electric telescopic rod 22 is located inside the grinding cylinder 1. The movable end of the electric telescopic rod 22 is fixedly connected to a connecting column 21, and the bottom end of the connecting column 21 is fixed to the top of the lifting plate 2. The extension and retraction of the electric telescopic rod 22 adjusts the height of the lifting plate 2 through the connecting column 21, thereby adjusting the height of the grinding head 4, that is, adjusting the depth of the grinding head 4 entering the grinding chamber 52. This can increase the distance between the grinding head 4 and the grinding seat 5, and facilitate the discharge of materials stuck between the grinding head 4 and the grinding seat 5 that cannot be ground.
[0032] like Figures 2 to 4 As shown in the figure, in this embodiment, a frame 31 is welded to the top of the lifting plate 2 and the side away from the tube frame 61. A drive motor 32 is fixed to the top of the frame 31, and the drive end of the drive motor 32 is located below the frame 31. A gear 33 is fixedly connected to the drive end of the drive motor 32. A rack 34 that meshes with the gear 33 is sleeved on the outer wall of the rotating shaft 3 and above the lifting plate 2.
[0033] like Figures 2 to 3 As shown in the figure, in this embodiment, a splash guard 51 is fixed at one end of the grinding seat 5 near the lifting connecting plate 2, a guide seat 41 is fixed at one end of the grinding head 4 near the lifting connecting plate 2, and a round hole for the rotating shaft 3 to pass through is opened in the middle of the guide seat 41, and an extension tube 42 is fixed at one end of the guide seat 41 away from the grinding head 4.
[0034] like Figures 2 to 3 As shown in the figure, in this embodiment, a crossbeam rod 43 is fixed on one side of the outer wall of the extension cylinder 42, and a pusher bar 44 is fixed at the bottom end of the crossbeam rod 43. The inclined end of the pusher bar 44 is located between the grinding head 4 and the grinding seat 5. When the grinding head 4 rotates, it will also drive the pusher bar 44 to rotate 360 degrees inside the grinding chamber 52. The pusher bar 44 stirs the raw material inside the grinding chamber 52, so that the raw material is evenly distributed inside the grinding chamber 52, increasing the contact surface with the grinding head 4, thereby improving the grinding efficiency of the material.
[0035] like Figures 1 to 2 As shown in the figure, in this embodiment, a feed pipe 7 is fixed inside the feed inlet on the cylinder cover 11, and the discharge end of the feed pipe 7 is located between the extension cylinder 42 and the anti-splash cylinder 51. The raw material is guided by the feed pipe 7 to fall between the anti-splash cylinder 51 and the extension cylinder 42. The raw material is continuously guided into the interior of the grinding chamber 52 by the guide seat 41, the extension cylinder 42 and the anti-splash cylinder 51, which plays a role in guiding and limiting the raw material, preventing the raw material from being left inside the grinding cylinder 1 and not being ground between the grinding head 4 and the grinding seat 5, thus avoiding waste of raw material.
[0036] In use, raw materials are fed into the feed pipe 7 and guided by the feed pipe 7 to fall between the anti-splash cylinder 51 and the extension cylinder 42. The raw materials are continuously fed into the grinding chamber 52 by the guide seat 41, the extension cylinder 42 and the anti-splash cylinder 51.
[0037] The drive motor 32 drives the gear 33 to rotate. Under the meshing transmission of the gear 33 and the rack 34, the rotating shaft 3 drives the grinding head 4 to rotate at high speed to grind the raw material located inside 53. When the raw material is ground to a certain precision, it falls into the grinding cylinder 1 and is discharged backward through the discharge pipe.
[0038] When the grinding head 4 rotates, it also drives the push bar 44 to rotate 360 degrees inside the grinding chamber 52. The push bar 44 stirs the raw material inside the grinding chamber 52, causing the raw material to be evenly distributed inside the grinding chamber 52.
[0039] At the same time, the airflow is pumped by pump 55 and enters the interior of the jet pipe 6 through the vertical connecting pipe 64, the metal hose 63, the rotating pipe 62, and the rotating shaft 3. The airflow is finally sprayed out through the jet pipe 6 and sprayed into the interior of the grinding chamber 52, causing the raw material located inside the grinding chamber 52 to be lifted or flow, and promoting the further uniform and comprehensive distribution of the raw material inside the grinding chamber 52.
[0040] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
