Spherical surface gasket and grinding clamp

Abstract

The invention discloses a spherical surface gasket and a grinding clamp. Protruding edges formed by outward extending are arranged at the circular outer edge of the spherical surface gasket, spherical curves of the protruding edges are the same as a spherical curve of a spherical surface body, and the two protruding edges are in bilateral symmetry; the grinding clamp comprises a clamp body and a plurality of positioning pins evenly distributed on the circumference of the top of the outer spherical surface of the clamp body, the left side and the right side of each positioning pin are provided with a left compression block and a right compression block which are used for compressing the protruding edges of the spherical surface gasket, the distance between each left compression block and the corresponding right compression block is larger than the diameter of the outer circle of the spherical surface gasket, each left compression block is fastened through a left screw, and each right compression block is fastened through a right screw; and the left screws and the right screws are in threaded and rotary connection to the outer spherical surface of the clamp body, and compression bottom faces, used for compressing the spherical surface gasket, of the left compression blocks and the right compression blocks are spherical arc faces. The spherical surface gasket can be rapidly clamped and reliably fixed through the grinding clamp, abrasive machining of grinding equipment to the outer spherical surface of the spherical surface gasket is facilitated, and the working efficiency is improved; and meanwhile, when the spherical surface gasket works, installation and positioning are facilitated, and the service life is prolonged.

Description

technical field [0001] The invention relates to a spherical gasket and a grinding fixture used for grinding the outer spherical surface of the spherical gasket. Background technique [0002] Spherical gasket is a gasket with spherical surfaces at both ends. It is mainly used in automobile differentials. The differential should adapt to severe bumps and can run at high speed for a long time in high and low temperature environments. It is installed between the housing of the device and the spherical gear to reduce friction and improve lubrication. For some spherical gaskets that require high precision on the outer spherical surface, they need to be clamped and fixed on the grinding fixture and then ground. However, the spherical gasket itself is smooth, and it is difficult to have a reliable clamping point on the grinding fixture, especially for The spherical gasket made of metal copper plate will cause a lot of trouble, so how to reasonably design the spherical gasket and gr...

Problems solved by technology

For some spherical gaskets that require high precision on the outer spherical surface, they need to be clamped and fixed on the grinding fixture and then ground. However, the spherical gasket itself is smooth, and it is difficult to have a reliable clamping point on the grinding fixture, especially for The spherical gasket made of metal copper plate will cause a lot of trouble, so how to design the spherical gasket and grinding fixture reasonably should be considered by the manufacturer

In addition, the spherical gasket is freely installed between the differential case and the spherical gear, and the radial position is easy to move during operation. Although the spherical surface can eliminate the contact deviation caused by its movement, it is obviously not conducive to the contact of the spherical gasket Friction, affecting service life
