Abstract
The utility model discloses a kind of chucking mechanism clamped for cylindrical sleeve to include chuck body, in chuck body and movable jaw, it is dispersed with the circumference of chuck body end face positioned at chuck radially, to each other away from equal guiding neck, movable jaw is slidably connected by being oriented to neck with chuck body, the movable jaw includes the matrix being connected with chuck body and is provided with the arc coaxial with chuck body along the axially outwardly extending corpus unguis of chuck body, the corpus unguis inner side of movable jaw.Cylindrical sleeve is loaded using arc, when compressing, distribution of force is more uniform between arc and cylindrical sleeve, while arc can suppress the deformation of cylindrical sleeve, is loaded more stable.
Description
Technical field
Mechanical processing machine parts technical field is the utility model is related to, it is especially a kind of to be used for what cylindrical sleeve clamped
Chucking mechanism.
Background technology
Bushing is the common components in plant equipment, is a kind of cylindric, and inside is hollow structure, be mainly used in axle and
Bearing is connected, and its outer surface is normally held among the internal diameter of bearing, and its inner surface is supported with the main shaft of rotation.Its effect is
Adjust bearing clearance, the cooperation of connecting shaft and bearing.Taper bush has the characteristics of wall is thin and length is longer, typically in clamping
The crimp of cylindrical sleeve is easily caused during processing, and is loaded and is loosely also easy to influence crudy, cause safety problem.
Utility model content
A kind of chucking mechanism clamped for cylindrical sleeve, including chuck body, in chuck body and movable jaw, in chuck body
Be dispersed with the circumference of end face positioned at chuck radially, to each other away from equal guiding neck, movable jaw is by being oriented to neck
It is slidably connected with chuck body, the movable jaw includes the matrix that is connected with chuck body and along the axially outwardly extending pawl of chuck body
Body, the corpus unguis inner side of movable jaw are provided with the arc coaxial with chuck body.
As a preferred embodiment, the central angle corresponding to the arc is 15 ° ~ 60 °.
Further, the chuck body is any one of scroll chuck body, chuck body or six dog chuck bodies.
The beneficial effects of the utility model are：Cylindrical sleeve is loaded using arc, due to arc plate shape
Feature, when compressing, arc contact with cylindrical sleeve forming face, distribution of force is more uniform, while arc can also
Suppress the deformation of cylindrical sleeve, be loaded more stable, improve the stabilization and safety coefficient during processing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is that Fig. 1 is left view.
Embodiment
Embodiment of the present utility model is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the present utility model easily.
Refer to Fig. 1.It should be clear that structure, ratio, size depicted in this specification institute accompanying drawings etc., only coordinating
Content disclosed in specification, so that those skilled in the art understands and reads, being not limited to the utility model can be real
The qualifications applied, therefore do not have technical essential meaning, the tune of the modification of any structure, the change of proportionate relationship or size
It is whole, in the case where not influenceing the effect of the utility model can be generated and the purpose that can reach, all should still fall in the utility model institute
The technology contents of announcement are obtained in the range of covering.Meanwhile in this specification it is cited as " on ", " under ", "left", "right",
The term of " centre " and " one " etc., understanding for narration is merely convenient to, and is not used to limit the enforceable scope of the utility model,
Its relativeness is altered or modified, in the case where changing technology contents without essence, when being also considered as the enforceable category of the utility model.
As shown in Figure 1 and Figure 2, a kind of chucking mechanism clamped for cylindrical sleeve, including chuck body 1, in the He of chuck body 1
Movable jaw 2, be dispersed with the circumference of the end face of chuck body 1 positioned at chuck radially, to each other away from equal guiding neck 3,
Movable jaw 2 is slidably connected by being oriented to neck 3 with chuck body 1, and the movable jaw 2 includes the matrix being connected with chuck body 1
21 and along the axially outwardly extending corpus unguis 22 of chuck body 1, the inner side of corpus unguis 22 of movable jaw 2 is provided with the arc coaxial with chuck body 1
Shape plate 23.
As a preferred embodiment, the central angle corresponding to the arc 23 is 15 ° ~ 60 °.
Further, the chuck body 1 is any one of scroll chuck body, chuck body or six dog chuck bodies.
During work, between cylindrical sleeve to be processed is put into three arcs 23, the side of spanner rotating chuck body 1 is used
On fastening spiral shell button 4, the center of circle of the flat thread with kinetoplast 21 to chuck body 1 in chuck draw close, and arc 23 is simultaneously in
The heart closes up.After arc 23 moves to a certain extent, cylindrical sleeve is clamped.Can starts lathe to cylindrical sleeve afterwards
Further it is machined.Cylindrical sleeve is loaded using arc 23, the characteristics of due to 23 shape of arc, pressed
When tight, the contact with cylindrical sleeve forming face of arc 23, distribution of force is more uniform, while arc 23 can also suppress cylinder
The deformation of shape bushing, it is loaded more stable, improves stabilization and safety coefficient during processing.
Above-described embodiment only illustrative principle of the present utility model and its effect are new not for this practicality is limited
Type.Any person skilled in the art can all be carried out without prejudice under spirit and scope of the present utility model to above-described embodiment
Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the essence disclosed in the utility model
God and all equivalent modifications completed under technological thought or change, should be covered by claim of the present utility model.
