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
The present invention relates to locking mechanism technical field, be specifically related to a kind of quick locking positioning means on axial workpiece.
Background technique
On axial workpiece locking and positioning generally lock with radial quick lock mechanism, but current most quick lock mechanism on axial workpiece during locking and positioning to axle apply radial direction on power skewness, easily make axial workpiece produce radial direction to depart from, axial workpiece precision is reduced.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned defect, a kind of quick locking positioning means on axial workpiece is provided, mechanism can on axle arbitrary position locking and positioning, and coupling mechanism force is along Axial and radial equiblibrium mass distribution, and axle can not be made to occur radial skew.
The technological scheme that the present invention solves the employing of its technical problem is as follows:
A kind of quick locking positioning means on axial workpiece, comprise axle sleeve, cone shaped elastic cover, spiral cover, described axle sleeve is stepped ramp type axle sleeve, the front end that diameter is little is tubular junction, axle sleeve axle center place is the axle center hole arranged, described elastic sleeve is arranged in joint, the maximum diameter of elastic sleeve is less than the internal diameter of joint, the little one end of elastic sleeve diameter is towards joint opening side, axle sleeve and the large connecting part, rear end of elastic sleeve diameter are protruding structure, protruding structure plays limited support effect to elastic sleeve, prevent elastic sleeve from occurring to slide in joint and affect the locking and positioning of axle, described spiral cover and axle sleeve joint outer circumferential face screw-thread fit, cover internal is also provided with the squeeze flow portion coordinated with elastic sleeve, squeeze flow portion inner peripheral surface is the conical surface with elastic sleeve cone match, squeeze flow portion outer circumferential face and axle sleeve joint inner peripheral surface screw-thread fit, screw-thread fit is convenient to be connected, and reliable lock, along with tightening gradually of spiral cover, spiral cover moves forward, the conical surface in squeeze flow portion of spiral cover and the cone match of elastic sleeve also extrude elastic sleeve, the power of level is decomposed in the radial direction of vertical direction, elastic sleeve is made to be pressed on axle, cone match changes the direction of power, and impacting force is distributed more uniformly, avoid the radial deflection causing axle, the precision of axle is not had a negative impact, and two screw-thread fit improves the reliability of locking and positioning, make locking and positioning more firm, and dynamics when tightening needed for reducing, more laborsaving.
Further, described spiral cover axle center place is provided with axle center hole equally, and the Hand of spiral of spiral cover screw-thread fit is identical, and axle center hole and axle are slidably matched, and makes this lock in place mechanism on axle, the spots localization of locking and positioning can be needed arbitrarily to lock.
Further, described axle sleeve, elastic sleeve, spiral cover concentric, concentric first ensure mutual cooperation can on axle locking and positioning, next ensure that axle uniform force diametrically, avoids axle to occur radial deflection, ensures the precision of axle.
The invention has the beneficial effects as follows: adopt such scheme, end cap squeeze flow portion and elastic sleeve cone match, make elastic sleeve be pressed on axle the radial direction that decomposes of power equilibrium, two screw-thread fit, more laborsaving, and make the more firm of compression, avoid axle to occur radial deflection, ensure the precision of axle.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Fig. 1 is cross section structure schematic diagram of the present invention.
Wherein: 1 is axle sleeve, 1.1 is joint, and 2 is elastic sleeve, and 3 is spiral cover, and 3.1 is squeeze flow portion, and 4 is axle.
Embodiment
A kind of quick locking positioning means on axial workpiece as shown in Figure 1, comprise the coaxial stepped ramp type axle sleeve 1 arranged, the elastic sleeve 2 of taper, spiral cover 3, the front end that axle sleeve 1 diameter is little is tubular junction 1.1, the axle center place of axle sleeve 1 arranges the axle center hole coordinated with axle, elastic sleeve 2 is arranged in joint 1.1, the maximum diameter of elastic sleeve 1.1 is less than the internal diameter of joint 1.1, the little one end of elastic sleeve 1.1 diameter is towards joint opening side, the connecting part, rear end that axle sleeve 1 is large with elastic sleeve 2 diameter is protruding structure, protruding structure plays limited support effect to elastic sleeve 2, the outer circumferential face screw-thread fit of the joint 1.1 of spiral cover 3 and axle sleeve 1, the inside of end cap 3 is also provided with the squeeze flow portion 3.1 coordinated with elastic sleeve 2, the inner peripheral surface in squeeze flow portion 3.1 is the conical surface with the cone match of elastic sleeve 2, the inner peripheral surface screw-thread fit of the outer circumferential face in squeeze flow portion 3.1 and the joint 1.1 of axle sleeve 1, and the Hand of spiral of two place's screw-thread fit is identical.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
