A rotary bearing follower

Abstract

The invention provides a rotary bearing follower, which includes a base body, a housing, and a rotary shaft passing through the housing along a central axis, the base body and the housing are both hollow structures, and are locked together to form a closed housing , and fixedly connected by bolts; the base body is sequentially installed with a seat ring, a first rolling element assembly and a taper sleeve along the axial direction; the outer circle of the rotary shaft is provided with a second rolling element assembly, a ferrule and an elastic sleeve in sequence; The taper sleeve is axially connected with the rotary shaft through the third rolling element assembly; the bottom of the rotary shaft is fixedly connected with a pressure head through screws. The slewing bearing follower sets the first rolling body assembly, the second rolling body assembly and the third rolling body assembly to make each movement a rolling motion, which reduces friction and improves response speed, and through the inner spherical surface of the seat ring, the The follower can automatically adjust the center, compensate the position and angle error between the pressing point and the center of rotation of the workpiece, and ensure that the workpiece rotates normally with the slewing 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 the machining accuracy and machining efficiency of mechanical parts are also getting higher and higher. When processing rotary parts, a chuck or other pressing mechanism is often required to clamp the workpiece and perform necessary rotation or indexing motion with other rotary mechanisms. In some cases, such as in the case of multi-axis simultaneous machining, the chuck cannot hold the workpiece or the chuck will interfere with the machining tool, or due to the manufacturing and machining errors of the parts, the workpiece is over-constrained after pressing, which affects the rotation of the workpiece. The normal rotation driven by the mechanism requires a set of follow-up mechanism to compress the workpiece...
