Description

Fixed brake caliper piston hole shutoff instrument

Technical Field

The utility model belongs to the technical field of automobile spraying, and particularly relates to a piston hole plugging tool for a fixed brake caliper.

Background

Currently, along with the improvement of living standard, automobiles are more and more popular in life, and the automobile brake comprises a brake caliper, wherein the brake caliper is a brake device for driving a brake pad to achieve a braking effect after the automobile is braked by stepping down. The fixed brake caliper is fixed on the inner side and the outer side of the whole caliper, and the clamping force of the inner side and the outer side is taken charge of by the piston. In the production process of the fixed brake calipers, the outer surfaces of the brake calipers are required to be sprayed with anti-corrosion and rust-proof paint, the piston holes on the brake calipers are used for installing pistons, and the inner walls of the piston holes cannot be stained with the paint during spraying so as not to influence use. The existing spraying equipment is automatic, the piston hole is plugged by using an adhesive tape firstly by manpower and then sprayed, and the adhesive tape is disposable, so that resource waste is caused.

Disclosure of Invention

The utility model aims to provide a fixed brake caliper piston hole plugging tool which can plug a piston hole when paint is sprayed on a caliper, prevent the paint from being sprayed into the piston hole and can be reused.

The technical scheme for realizing the aim of the utility model is as follows: the utility model provides a fixed brake calliper piston hole shutoff instrument, includes sealing washer and spring, sealing washer is two, fixes respectively the both ends of spring, the length is greater than the distance between two opposite piston holes on the calliper under the spring natural state.

The two sealing gaskets are fixedly connected through the spring, the length of the spring in a natural state is larger than the distance between the two piston holes in the caliper, and when the caliper is required to be sprayed, the spring is only required to be pressed tightly by force, the sealing gaskets are aligned to the piston holes to be installed, and the tool is taken down after the spraying is finished and used for next spraying.

Further, be provided with on the sealing pad with the corresponding boss of piston hole, the boss can be shutoff go up the piston hole, be located the bearing surface of sealing pad upper boss bottom is pasted tightly the edge of piston hole, and the seal is more tight, can not let the paint spout on the boss, and then infiltrate in the piston hole.

Furthermore, the sealing gasket is made of polytetrafluoroethylene, and has the characteristics of acid resistance, alkali resistance and solvent resistance. Because paint needs to be sprayed on the calipers, paint is sprayed on the periphery of the piston hole blocked by the sealing gasket, and polytetrafluoroethylene has good self-lubricating property and cannot be adhered to the paint on the periphery of the piston hole.

Further, two support bars with bending elasticity are arranged between the sealing gaskets, such as elastic metal bars, an auxiliary supporting effect is achieved, a fixed caliper is sprayed by a common electrostatic spraying method, high-temperature solidification is needed after spraying, failure risks of the springs can exist at high temperature, the support bars with the auxiliary supporting effect are increased, and the risk of plugging failure caused by failure of the springs can be effectively avoided.

Further, the sealing gasket is provided with a convex connecting part with the same size as the inner diameter of the spring, and the spring is sleeved on the connecting part. The spring sleeved on the connecting part can be replaced conveniently when the elasticity is insufficient, and the sealing gasket can also be replaced conveniently, so that the later maintenance is convenient.

By adopting the technical scheme, the utility model has the following beneficial effects: (1) By arranging the plugging tool with a simple structure, the piston hole can be plugged when the calipers are sprayed, so that paint is prevented from entering the piston hole; (2) simple structure, flexible application and repeated use; and (3) the cost is low, the price is low, and the cost is saved.
