Description

Technical Field

[0001] The invention relates to the field of spraying facilities, in particular to a surface spraying device for automobile brake discs. Background Art

[0002] The brake disc is a disc-shaped component that rotates with the wheel. When the brake pedal is pressed, the brake caliper clamps the brake disc and slows down or stops the vehicle through friction. As an important component of the automobile braking system, the quality and performance of the brake disc are directly related to driving safety.

[0003] When processing brake discs, it is usually necessary to spray the friction area of ​​the brake disc to improve the wear resistance of the brake disc. However, after processing, the brake disc is usually placed on the material rack in the warehouse for storage, waiting for the next process. During storage, dust in the air will adhere to the brake disc, causing the coating to be blocked by dust and unable to adhere firmly to the brake disc during spraying, resulting in poor spraying effect.

At the same time, when the dust is being cleaned, the cover will cover the dust and suck it away through the air duct to avoid the dust from flying and falling on the coating during the cleaning process, thereby further improving the spraying effect.

[0015] 2. When the brush barrel just starts to move, the lifting wheel will roll synchronously with the lower end of the lifting rail. When the lifting wheel rolls to the lower end inclined surface of the lifting rail, the lifting spring will gradually restore its deformation to push the wheel seat onto the limit push cap, thereby raising the lifting wheel. After the brush barrel rotates one circle, the raised lifting wheel will be located at the upper end of the lifting rail and roll along the inclined surface at the upper end of the lifting rail to drive the wheel seat to move up and push the limit push cap, thereby driving the convex seat to move up. At this time, the compression spring contracts and deforms to adapt to the upward movement of the convex seat, and the cover and brush barrel are driven upward by the upward convex seat to separate them from the brake disc, so as to avoid the brush barrel from contacting the sprayed area when continuing to rotate for spraying, thereby effectively preventing the coating from being damaged after spraying.

A boss 22 is fixedly installed on the lower end of the quadrangular prism 33. The quadrangular prism 33 serves to guide the cover shell 20. The end of the boss 22 is fixed to the cover shell 20. The boss 22 serves to connect. A clamping spring 32 is wound around the outer side of the quadrangular prism 33. The clamping spring 32 serves to reset the raised brush cylinder 36. One end of the clamping spring 32 is fixed to the upper end of the boss 22, and the other end of the clamping spring 32 is fixed to the lower end of the swing frame 17.

[0030] The upper end of the quadrangular prism 33 is inlaid with an anti-slip cap 34, which prevents the quadrangular prism 33 and the swing frame 17 from separating, and the anti-slip cap 34 is fitted to the upper end of the swing frame 17. A connecting ear 26 extends from the side of the protrusion 22, and a hexagonal prism 23 is fixedly installed on the upper end of the connecting ear 26, which connects the hexagonal prism 23.

[0032] During spraying, the brake disc 37 is placed on the tray seat 9. At this time, the center column 7 is inserted into the shaft hole on the brake disc 37 to position the brake disc 37 so that the center of the brake disc 37 corresponds to the drive shaft 16. At the same time, the positioning column 8 is inserted into the mounting hole on the brake disc 37 to prevent the brake disc 37 from rotating. Then the second servo motor 10 drives the threaded rod 12 to rotate, so that the slide 11 moves downward, and then drives the spray head 19 and the brush barrel 36 to move downward, so that the brush barrel 36 can fit on the brake disc 37. The spray head 19 is close to the top of the brake disc 37, and then the No. 1 servo motor 3 drives the drive shaft 16 to rotate, thereby driving the brush barrel 36 and the spray head 19 to rotate in a circle.

During this process, when the brush barrel When the lifting wheel 31 starts to move, the lifting wheel 31 will roll synchronously with the lower end of the lifting rail 28. When the lifting wheel 31 rolls to the lower end inclined surface of the lifting rail 28, the lifting spring 25 will gradually restore its deformation to push the wheel seat 27 onto the limit push cap 24, so that the lifting wheel 31 is raised. When the brush cylinder 36 rotates one circle, the raised lifting wheel 31 will be located at the upper end of the lifting rail 28 and roll along the inclined surface of the upper end of the lifting rail 28 to drive the wheel seat 27 to move up to push the limit push cap 24, thereby driving the cam The seat 22 moves up, and the compression spring 32 contracts and deforms to adapt to the upward movement of the convex seat 22, so that the cover shell 20 and the brush cylinder 36 are driven by the upward convex seat 22 to move up and separate from the brake disc 37. During this process, the drive shaft 16 continues to drive the spray head 19 to rotate to the starting position of spraying, thereby completing a circle of spraying operation. After the spraying is completed, the slide 11 drives the spray head 19 and the brush cylinder 36 to move up, and then the spray head 19 and the brush cylinder 36 are reversed and reset to wait for the next spraying process.
