Rotary bearing follower

Abstract

The invention provides a rotary bearing follower. The rotary bearing follower comprises a base body, a shell and a rotary shaft penetrating through the shell along a central shaft, wherein the base body and the shell are both of a hollow structure, are oppositely clamped to form a closed shell and are fixedly connected through a bolt; a seat ring, a first rolling body assembly and a taper sleeve are sequentially installed on the base body in the axial direction; a second rolling body assembly, a ferrule and an elastic sleeve are sequentially arranged on the outer circle of the rotary shaft; the taper sleeve is in rolling connection with the rotary shaft in the axial direction through a third rolling body assembly, and the bottom of the rotary shaft is fixedly connected with a pressing head through a screw. According to the rotary bearing follower, through the arrangement of the first rolling body assembly, the second rolling body assembly and the third rolling body assembly, all motions are rolling motions, friction is reduced, and the response speed is increased; through the inner spherical surface of the seat ring, the follower can be automatically aligned, position and angle errors of a pressing point and the rotary center of a workpiece can be compensated, and it is ensured that the workpiece normally rotates along with a rotary mechanism while being pressed by the follower.

Description

technical field [0001] The invention relates to a bearing follower, in particular to a rotary bearing follower. Background technique [0002] With the continuous development of the machinery industry and the intensification of industry competition, the requirements for machining accuracy and machining efficiency of mechanical parts are also getting higher and higher. When processing rotary parts, chucks or other pressing mechanisms are often required to clamp the workpiece and perform necessary rotary or indexing movements with other rotary mechanisms. In some cases, such as in the case of multi-axis linkage processing, the chuck cannot hold the workpiece or the chuck will interfere with the processing tool, or due to part manufacturing and processing errors, the workpiece is over-constrained after pressing, affecting the rotation of the workpiece The normal rotation driven by the mechanism requires a set of follow-up mechanism to compress the workpiece and move with the ro...
