Abstract

The invention relates to a flexible self-centering device with high stiffness, which comprises a plurality of positioning elements. The positioning elements are connected into an integral structure through rubber strips, the outer part of the integral structure is in a column shape, and the inner part forms a circular conical surface. The invention has the advantages of high precision, long service life, self-centering, simple structure and low cost.

Description

technical field [0001] The invention relates to a self-centering device for centering gear processing, in particular to a flexible and high-rigidity self-centering device. Background technique [0002] Gears are the basic parts of mechanical transmission. The gear grinding, hobbing, and shaving processes are the key processes of gear manufacturing. The centering accuracy of the grinding, hobbing, and shaving fixtures and the long life of the centering accuracy directly affect the gear. precision. [0003] There are four types of self-centering devices commonly used at present: elastic expansion sleeves, bellows sleeves, dense bead sleeves, and liquid plastic mandrels. [0004] The design of the elastic expansion sleeve is to separate continuous grooves in the circumferential direction of the expansion sleeve. The positioning mandrel is used to cooperate with the elastic expansion sleeve, and an axial force is applied to the end surface of the elastic expansion sleeve to mak...
