Abstract

The invention discloses a fixture which is used for grinding a spherical gasket and is characterized in that the fixture comprises a flange and a clamp head which are fixedly connected; the clamp head has a same spherical arc surface as the spherical gasket, and the inside of the clamp head is provided with an electromagnetic coil. The fixture can fast clamp and fix a plurality of spherical gaskets, and is convenient for the processing device to finely process the spherical gasket with high efficiency. The accuracy and the surface smoothness of the spherical gasket are greatly increased without greatly increasing the processing cost..

Description

【Technical field】 [0001] The invention relates to a fixture, in particular to a fixture for grinding spherical gaskets. 【Background technique】 [0002] Spherical gasket is a kind of gasket with spherical arc surface. The key of spherical gasket is its spherical precision and smoothness, such as automobile gear gasket, which is used to protect automobile gear and other parts and avoid direct contact between gear and other parts , to reduce the wear and damage of gears and other parts. When in use, the spherical surface of the automotive gear gasket needs to match the arc surface of the adjacent gear. The gasket has high precision and the friction between the gasket and the gear and other parts is small. , its wear is small, otherwise it will cause serious wear of the three, affecting the safety of the car and the service life of the components. At present, domestic and foreign spherical gaskets are all formed by punching machines, and their spherical error and smoothness are...
