Abstract
The invention discloses a clamping device. The clamping device comprises a clamp body, a compression sleeve and a compression nut. The clamp body is a step shaft with an outer spline. The large-diameter surface of the outer spline is a cone. The compression sleeve is a hollow cone, and the outer spline is arranged on the surface. An inner hole of the compression sleeve is in precision-positioning clearance fit with the outer circle of the clamp body, the requirement on the coaxiality is guaranteed, and the compression nut is connected with an external thread end of the clamp body. The clamp body, the large-diameter conical surface of the outer spline of the compression sleeve and the large-diameter surface of an inner spline of a workpiece can be attached by screwing the compression nut, and thus clamping and positioning of the workpiece are achieved. The clamping device is ingenious in structural design, high in positioning accuracy and capable of being widely used for grinding and turning of various workpieces with inner splines.
Description
Technical field
The present invention relates to machining technology field, more particularly to a kind of clip dress suitable for internal spline part processing
Put.
Background technology
In the part course of processing with internal spline, often running into design requirement needs internal spline to have together with outer round surface
The situation that axle degree is required, current processing method is all to take dabber clamp, and mandrel surface is cylinder, for convenient mounting and clamping, core
Axle is cylindrical to have certain gap with spline aperture, and the method cannot ensure that higher axiality is required, processing effect is less managed
Think.
The content of the invention
In view of this, to overcome the deficiencies in the prior art, the present invention provides a kind of clamping device, easy to install and use,
Positioning precision is high, can be widely used in the various grindings of the workpiece with internal spline and turnery processing.
For achieving the above object, technical scheme is as follows：
A kind of clamping device, including clamp body, clamping sleeve and clamp nut, the clamp body are the step for being provided with external splines
Axle, the clamping sleeve is hollow cone, and its endoporus is cylindrical with the clamp body to be coordinated for gap, the clamp nut and institute
The male end connection of clamp body is stated, the big footpath surface of external splines of the clamp body is cone shape, its large and small end diameter and work
The large and small footpath size of part internal spline is adapted, specially：The cone outside diameter is slightly larger than the big footpath size of workpiece internal spline,
End diameter is slightly less than the big footpath size of workpiece internal spline.
The surface of the clamping sleeve is provided with external splines, and its large and small end diameter is mutually fitted with the large and small footpath size of workpiece internal spline
Match somebody with somebody.The external splines outside diameter is slightly larger than the big footpath size of workpiece internal spline, and end diameter is slightly less than the big footpath chi of workpiece internal spline
It is very little.
The clamping sleeve endoporus is coordinated with the gap of the cylindrical employing precision positioning of clamp body, it is ensured that axiality is required.
During use, tightening clamp nut can make the clamp body and the big footpath conical surface of clamping sleeve external splines big with workpiece internal spline
Footpath surface is fitted, so as to realize the clamping to workpiece and positioning.
The invention has the beneficial effects as follows, smart structural design, it is ensured that the axiality of processing is required, installed and user
Just, positioning precision is high, can be widely used in the various grindings of the workpiece with internal spline and turnery processing.
Description of the drawings
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
Accompanying drawing to be used needed for having technology description is briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the present invention.
In figure, 1, clamp body, 2, clamping sleeve, 3, clamp nut, 4, workpiece.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
With reference to Fig. 1, a kind of clamping device, including clamp body 1, clamping sleeve 2 and clamp nut 3, clamp body 1 is to be provided with outer flower
The Step Shaft of key, the fixture, the 1 big footpath surface of external splines is cone shape, its large and small end diameter is big with workpiece internal spline,
Path size is adapted, the cone outside diameter is slightly larger than the big footpath size of 4 internal spline of workpiece, and end diameter is slightly less than work
The big footpath size of 4 internal spline of part.
The clamping sleeve 2 is located at the middle part of clamp body 1, and which is hollow cone, outside 2 endoporus of clamping sleeve and clamp body 1
Circle coordinates for gap, it is ensured that the axiality of processing is required.The surface of clamping sleeve 2 is provided with external splines, its large and small end diameter and work
The large and small footpath size of 4 internal spline of part is adapted.The external splines outside diameter is slightly larger than the big footpath size of 4 internal spline of workpiece, and small end is straight
Footpath is slightly less than the big footpath size of 4 internal spline of workpiece.
Clamp nut 3 is connected with the male end of the clamp body 1, closely adjacent with clamping sleeve 2, and together workpiece 4 is pressed
Tightening position.
During use, tightening clamp nut 3 can make the clamp body 1 and the big footpath conical surface of 2 external splines of clamping sleeve with flower in workpiece 4
The big footpath surface laminating of key, so as to realize clamping and positioning to workpiece 4.
Presently preferred embodiments of the present invention is the foregoing is only, not to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
