Abstract
The invention discloses a shaft sleeve. The shaft sleeve is characterized by comprising an outer sleeve and an inner sleeve; the outer sleeve is provided with an outer sleeve cavity; the inner sleeve is provided with an inner sleeve cavity; the inner sleeve is arranged in the outer sleeve cavity in a form of moving in an axial direction; and the inner sleeve is under a radial pressure of the wall of the outer sleeve cavity when moving along the axial direction so as to reduce the diameter of the inner sleeve cavity. By using the detachable shaft sleeve, a shaft end is effectively protected from being worn, and therefore, a shaft is protected. The clamping force to the shaft can be increased in the mounting process of the shaft sleeve, so that the shaft sleeve is firmer is clamping and more convenient to use.
Description
Technical field
The present invention relates to a kind of axle sleeve.
Background technique
Figure 1 shows that a kind of workpiece 10 structural representations.The spindle nose 12 that it comprises workpiece body 11 and is arranged at workpiece body 11 two ends.The diameter of spindle nose 12 is far smaller than the diameter of workpiece body 11.This workpiece is also referred to as the little shaft head structure of large workpiece.In this type of workpiece process, need to drive workpiece body 11 rotations by axle 12, to carry out grinding or other processing.Therefore, need clamping spindle nose 12 or lift spindle nose 12, drive spindle nose 12 and then drive the purpose that workpiece body 11 is rotated to reach.In course of working, axle sleeve commonly used can't the firm grip spindle nose, causes producing relative movement and the spindle nose that rubs between spindle nose and the axle sleeve.Because rubbing action, tend to appear at rotate or clamping process in the impaired phenomenon of spindle nose 12, cause greatly reduce the working life of workpiece.
Summary of the invention
The objective of the invention is provides a kind of axle sleeve of protecting axle in order to overcome deficiency of the prior art.
For realizing above purpose, the present invention is achieved through the following technical solutions:
Axle sleeve is characterized in that, comprises jacket and inner sleeve, and described overcoat is provided with the overcoat tube chamber; Described inner sleeve is provided with internal canula lumen; Described inner sleeve can be arranged in the overcoat tube chamber with moving vertically; Described inner sleeve is subject to the radial pressure of overcoat wall of the lumen when moving vertically and dwindles the diameter of internal canula lumen.
Preferably, described overcoat lumen diameter is consistent, described inner sleeve outward without leave the end rise vertically gradually little.
Preferably, described overcoat lumen diameter is consistent, described inner sleeve outward without leave the end rise gradually large vertically.
Preferably, described overcoat lumen diameter is vertically gradually little from the end; Described inner sleeve outward without leave the end rise gradually large vertically; In the same direction, overcoat tube chamber vary in diameter changes opposite with the inner sleeve external diameter.
Preferably, described inner sleeve end is provided with the radially groove that extends vertically.
Preferably, described groove number is more than two, distributes in the circumferential direction of the circle.
Preferably, also comprise link, described overcoat is connected by link with inner sleeve; Described link connects in overcoat and the inner sleeve process, and described link drives described inner sleeve and described overcoat relative movement.
Preferably, described link is threaded connector, described threaded connector and described overcoat and inner sleeve screw-thread fit.
Preferably, described inner sleeve end is provided with the shoulder that radially extends, and described shoulder is provided with internal thread through hole; Be provided with axially extended interior threaded hole on the overcoat wall; Internal thread through hole and interior threaded hole position are oppositely arranged; Described threaded connector and described internal thread through hole and interior threaded hole screw-thread fit.
Preferably, described threaded connector is bolt.
Preferably, described inner sleeve and overcoat removably connect.
Axle sleeve among the present invention, inner sleeve insert in the intraluminal process of overcoat, are subject to the pressure of overcoat wall of the lumen and radial contraction, thereby dwindle the diameter of internal canula lumen, so that inner sleeve clamps spindle nose.The inner sleeve end is provided with axially extended groove, makes its end form foliaceous, is conducive to contraction deformation and clamps spindle nose.Inner sleeve external diameter and overcoat lumen diameter all have certain Changing Pattern, so that overcoat can either be exerted pressure to inner sleeve, can not cause producing again the gap between the two.Utilize threaded connector to connect overcoat and inner sleeve, both both can be removably connected, can utilize again the characteristics of screw-thread fit, drive inner sleeve and overcoat and produce relative movement, thereby so that overcoat compressing inner sleeve clamps spindle nose.The present invention is not only applicable to spindle nose shown in Figure 1, need to be equally applicable to the axle of clamping.
Utilize dismountable axle sleeve, can effectively protect spindle nose to avoid wearing and tearing, provide protective action thereby can be axle.Can increase the chucking power to axle in the installation process of the present invention, clamping is more firm, uses more convenient.

Embodiment
Below in conjunction with accompanying drawing the present invention is described in detail:
Such as Fig. 2, Fig. 3 and shown in Figure 4, axle sleeve comprises overcoat 1 and inner sleeve 2.Overcoat 1 is provided with overcoat tube chamber 11.12 the axial diameters in overcoat end are gradually little without leave in the overcoat tube chamber 11.Inner sleeve 2 is provided with internal canula lumen 21.The outer without leave inner sleeve end 22 axial diameters of inner sleeve 2 increase gradually.That is, in the same direction, the variation of overcoat tube chamber 11 diameters is opposite with the variation of inner sleeve external diameter.22 places, inner sleeve end are provided with the radially groove 23 that extends vertically.Radially the number of groove 23 is 3, so that inner sleeve end 22 forms three blades 24.
Be provided with the shoulder 26 that radially extends on the outer wall at 25 places, inner sleeve 2 the other end.Shoulder 26 is provided with internal thread through hole 27.Be provided with interior threaded hole 13 on the wall of overcoat 1.Internal thread through hole 27 is relative with interior threaded hole 13 positions.Bolt 3 passes internal thread through hole 27 and interior threaded hole 27 screw-thread fit.Bolt 3 also is screw-thread fit with internal thread through hole 27.
Bolt 3 passes internal thread through hole 27 and cooperates with interior threaded hole 13, turns in the process of bolt 3, can make overcoat 1 and the axial relative movement that inner sleeve 2 produces along axle 14, and inner sleeve 2 is inserted in the overcoat tube chamber 11.Because the diameter of overcoat tube chamber 21 dwindles gradually, the external diameter of inner sleeve 2 increases gradually, inserts in the process of overcoat tube chamber 11 in inner sleeve 2, and the outer wall of inner sleeve 2 is subject to the pressure of overcoat tube chamber 21 walls.Therefore, three blade 24 radial contraction, thus can clamp the axle that is positioned at internal canula lumen 21.
Embodiment among the present invention only is used for that the present invention will be described, does not consist of the restriction to the claim scope, and other substituting of being equal in fact that those skilled in that art can expect are all in protection domain of the present invention.
