Quick locking and positioning mechanism for axis parts

Abstract

The invention relates to the technical field of locking mechanisms, in particular to a quick locking and positioning mechanism for axis parts. The quick locking and positioning mechanism for axis parts comprises a shaft sleeve, a conical elastic sleeve and a screw cap. The shaft sleeve is a step-type shaft sleeve, the small-diameter front end of the shaft sleeve is a tubular connecting part, the axis of the shaft sleeve is an axis hole, the elastic sleeve is arranged in the connecting part, the largest diameter of the elastic sleeve is smaller than the inner diameter of the connecting part, the small-diameter end of the elastic sleeve faces the opening side of the connecting part, the position where the shaft sleeve and the large-diameter rear end of the elastic sleeve are connected is of a convex structure, the screw cap is in thread fit with the outer circumferential face of the connecting part of the shaft sleeve, an extrusion connecting part matched with the elastic sleeve is arranged in an end cover, the inner circumferential face of the extrusion connecting part is a conical face matched with the conical face of the elastic sleeve, and the outer circumferential face of the extrusion connecting part is in thread fit with the inner circumferential face of the connecting part of the shaft sleeve. The mechanism can be locked and positioned to any position of a shaft, locking force is evenly distributed in the radial direction of the shaft, and the shaft is prevented from shifting in the radial direction.

Description

technical field [0001] The invention relates to the technical field of locking mechanisms, in particular to a quick locking and positioning mechanism for shaft parts. Background technique [0002] The locking and positioning on the shaft parts is generally locked by a radial quick-lock mechanism, but most of the current quick-lock mechanisms exert uneven radial force distribution on the shaft when the shaft parts are locked and positioned, which is easy to make the shaft Such parts produce radial deviation, which reduces the precision of shaft parts. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fast locking and positioning mechanism for shaft parts in view of the above defects. This mechanism can lock and position at any position on the shaft, and the locking force is evenly distributed along the radial direction of the shaft. , will not cause radial offset of the shaft. [0004] The technical scheme that ...
