A surface treatment device for automotive metal parts

Abstract

This invention discloses a surface treatment device for automotive metal parts, belonging to the field of metal part surface treatment technology. It avoids the time-consuming nature of manual grinding and prevents poor grinding accuracy caused by worker arm fatigue and tremors. Furthermore, by using symmetrical grinding rollers positioned on one side of the sprocket drive assembly, it avoids the limitation of mechanical grinding devices only grinding one side of the annular part. This invention enables simultaneous grinding of both sides of the annular part, reducing the need for adjustments and improving grinding efficiency. Secondly, the air pump fixedly mounted on one end of the base plate, along with an air tank connected to one end of the pump via an air pipe and a jet nozzle on one side of the air tank, works in conjunction with the air pump. This allows for the removal of metal particles from the surface of the annular metal part during mechanical grinding, preventing scratches caused by metal particles and further improving the grinding effect.

Description

TECHNICAL FIELD

[0001] The application relates to an automobile metal part surface treatment device and belongs to the technical field of metal part surface treatment. BACKGROUND

[0002] Automobile parts are the basis of the automobile industry and are necessary factors for the sustainable and healthy development of the automobile industry. The parts are mainly made of metal materials and non-metal materials, and have various shapes. In order to better adapt the parts to each other, the surface of the parts needs to be polished. Polishing is a kind of surface modification technology, which generally processes parts through relatively rough objects or specific roughness.

[0003] At present, the polishing of automobile metal parts, especially the polishing of annular parts, is generally divided into two polishing methods; one is manual polishing, and the other is mechanical polishing. Manual polishing generally takes a long time, which easily causes hand shaking and affects the polishing accuracy of the annular part. The mechanical polishing method generally polishes the outer surface of the metal part first, and then polishes the inner surface of the metal part, so the polishing device needs to be adjusted, which is troublesome, time-consuming and labor-intensive, and affects the polishing efficiency. In addition, during the polishing process, metal particles will fall on the area that has not been polished on the surface of the metal part, so the metal particles remaining on the surface of the metal part are easy to scratch the surface of the metal part during the polishing process, thereby further reducing the polishing quality of the metal part.

[0028] In use, the invention first activates the electric telescopic rod 16 to pull the main support plate 15 towards one end of the inverted U-shaped plate 10. Then, the second cylinder 7 is activated to pull the moving plate 9 below the inverted U-shaped plate 10 to the other end of the inverted U-shaped plate 10. Next, the worker first removes the toothed chain inside the sprocket drive assembly 28, then loosens the nut 32 on the side surface of the screw 31.

Therefore, the spacing between the drive rollers 11 and the other set of drive rollers 11 is adjusted. Then, the second cylinder 7 is activated, thus pushing the moving plate 9 closer to the annular shape.

Then, the air box 22 is magnetically attached to the front surface of the moving plate 9, and the roller 25 on one side surface of the air box 22 clamps one end of the annular metal component. At this time, the jet nozzle 23 will be aimed at the inner and outer surfaces of the annular metal component respectively. At the same time, the first cylinder 2 on the upper surface of the base plate 1 is activated, so that the first cylinder 2 will push the horizontal plate 3 and the symmetrical conveying roller 4 to support the annular metal component. Then, the air pump 5, the reduction motor 8 and the motor 30 are activated simultaneously, so that the motor 30 will drive the grinding roller 13 to grind the inner and outer surfaces of the metal component at the same time. The reduction motor 8 will drive the annular metal component to rotate slowly through the drive roller 11. At the same time, the air pump 5 will blow away the metal particles on the inner and outer surfaces of the annular metal component through the air pipe 6 and the jet nozzle 23, thereby further improving the grinding effect of the metal component.
