Description

Excircle clamping and positioning mechanism

Technical Field

The utility model relates to a brake disc production technical field especially relates to an excircle centre gripping positioning mechanism.

Background

The brake disc, in brief, is a round disc, which also rotates when the vehicle is moving. The brake caliper clamps the brake disc to generate braking force, and when the brake is stepped on, the brake caliper clamps the brake disc to play a role in speed reduction or parking. The brake disc has good braking effect and is easier to maintain than a drum brake. The brake comprises a disc brake, a drum brake and an air brake, and many old vehicles are provided with front discs and rear drums. The front and the rear of the vehicle are disk brakes. Because the heat dissipation of the disc brake is better than that of the drum brake, the disc brake is not easy to generate heat recession in a high-speed braking state, and the high-speed braking effect is good. But at low speed cold brake, the braking effect is not as good as that of drum brake. The price is more expensive than the drum brake. Therefore, many medium and high-grade cars adopt full disc brakes, while ordinary cars adopt front disc and rear drum, and drum brakes are still adopted at relatively low speed and in trucks and buses with large braking force.

In the production process of brake disc, receive the shape influence of brake disc, its circular shape design makes a lot of general fixture carry out normal use, even can carry out the adaptation of forcing and use, also can cause the brake disc to cause the damage in the course of working, so to the brake disc personnel can use excircle fixture usually, and excircle fixture is one kind can carry out the centre gripping to circular processing thing and can not cause the fixture of scraping the damage to the centre gripping thing, excircle fixture in the market is in the in-service use process, for the brake disc that more different thickness of adaptation and size are different, excircle fixture can be equipped with the function of adjusting, in order to improve excircle fixture's market competition, provide the excircle fixture of the personnel's of being convenient for operation and regulation for the personnel, increase excircle adjustment mechanism's production innovation enthusiasm, a excircle centre gripping positioning mechanism is proposed to this end.
