A surface derusting processor for disc metal castings

Abstract

The invention discloses a surface derusting processor for disc-like metal castings, which belongs to the technical field of casting derusting. A surface derusting processor for disc-like metal castings can be up and down and left and right through a pair of casting positioning mechanisms. The moving grinding roller is used together. After positioning the disc castings, according to the different surfaces of the castings to be processed, the horizontal and vertical positions of the grinding rollers are adjusted to be suitable for targeted treatment of the plane and convex surfaces of the castings. , effectively improve the processing flexibility of the device, and by adding a pushable oil seal mechanism in the casting positioning mechanism, the oil seal mechanism can realize the penetration of liquid grease into the oil seal sponge under the push of the oil filling piston, and the oil seal sponge and the outer end wall of the casting form a At this time, the oil-sealed sponge with a certain amount of oil effectively improves the tightness of the attachment to the outside of the casting, and on the other hand, it also effectively protects the casting when it is clamped.

Description

technical field [0001] The invention relates to the technical field of rust removal for castings, in particular to a surface rust removal processor for disc metal castings. Background technique [0002] The brake disc is an important part of the brake system. It belongs to the disc metal casting. The brake disc is usually formed by stamping. During the production process, the surface is prone to burrs. The existence of these burrs makes the surface of the brake disc It becomes rough and uneven, and when it is used in equipment, it often causes damage such as scratches to the equipment. Therefore, after the stamping of the brake disc is completed, it is necessary to deburr and derust the outer surface of the brake disc. [0003] The traditional derusting method often adopts manual deburring and grinding, and the effect is average. It is characterized in that the working environment is harsh, there is more dust, the safety factor is low, the operator consumes a lot of physica...

Problems solved by technology

[0003] The traditional derusting method often adopts manual deburring and grinding, and the effect is average. It is characterized in that the working environment is harsh, there is more dust, the safety factor is low, the operator consumes a lot of physical energy, and the efficiency of grinding is not very high; the prior art There is also mechanical derusting and grinding of the brake disc. Because the brake disc is generally divided into upper and lower end faces, and one side is convex, that is, one side of the brake disc is a convex disc. During the grinding process, due to the uneven structure of the two sides, If a fixed mechanical grinder is used, it is not convenient to uniformly grind the two sides of the brake disc, and the flexibility of the processing operation is relatively poor; in addition, the casting generally needs to be positioned during the casting process, which is often done in the prior art. The fixture positions the side wall of the casting. The clamping stability of the general fixture needs to be improved, and at the same time, the protection of the end face of the casting during the clamping and positioning process also needs to be improved.
