Abstract

The utility model discloses a positioning and clamping device, personally experience sth. Part of the body, compress tightly cover and gland nut including anchor clamps, the step axle of the anchor clamps body for being equipped with the external splines, the big footpath of external splines surface is the cone. Compressing tightly the cover and being hollow cone, the surface is equipped with the external splines. Compress tightly the clearance fit that the external circle of set hole and anchor clamps adopted precision positioning, guarantee the axiality requirement, gland nut and the specific outer threaded end connected of clamp. It can make the anchor clamps body and compress tightly the big footpath of set external splines conical surface and the laminating of the big footpath of work piece internal spline surface to screw up gland nut to the realization is to the tight and location of clamp of work piece. The utility model discloses structural design is ingenious, and positioning accuracy is high, can extensively be used for the work piece grinding and the lathe work of various in -band splines.

Description

A kind of positioning clamping device
[technical field]
This utility model relates to Machining Technology field, particularly to a kind of location being applicable to internal spline part processing Clamping device.
[background technology]
In the part course of processing with internal spline, often running into design requirement needs internal spline and outer round surface to have together The situation that axle degree requires, current processing method is all that to take dabber clamp, mandrel surface be cylindrical, for convenient mounting and clamping, core There is certain gap in axle cylindrical and spline aperture, and the method cannot ensure higher axiality requirement, and processing effect is less managed Think.
[utility model content]
In view of this, for overcoming the deficiencies in the prior art, this utility model provides a kind of positioning clamping device, installs and makes With convenient, positioning precision is high, can be widely used in workpiece grinding and the turnery processing of various band internal spline.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of positioning clamping device, including clamp body, clamping sleeve and clamp nut, described clamp body is to be provided with external splines Step Shaft, described clamping sleeve is the cone of hollow, and its endoporus and described clamp body cylindrical are matched in clearance, described clamp nut It is connected with the male end of described clamp body.
Further, the surface, external splines big footpath of described clamp body is cone shape, its large and small end diameter and workpiece internal spline Large and small footpath size is suitable.Particularly as follows: described cone outside diameter is slightly larger than workpiece internal spline big footpath size, end diameter It is slightly less than workpiece internal spline big footpath size.
The surface of described clamping sleeve is provided with external splines, and its large and small end diameter footpath large and small with workpiece internal spline size is fitted mutually Join.Described external splines outside diameter is slightly larger than workpiece internal spline big footpath size, and end diameter is slightly less than workpiece internal spline big footpath chi Very little.
Described clamping sleeve endoporus uses the matched in clearance of precision positioning with clamp body cylindrical, it is ensured that axiality requirement.
During use, tighten clamp nut and described clamp body and the clamping sleeve external splines big footpath conical surface can be made big with workpiece internal spline Fitting in surface, footpath, thus realizes the clamping to workpiece and location.
The beneficial effects of the utility model are, smart structural design, it is ensured that the axiality requirement of processing, install and use Convenient, positioning precision is high, can be widely used in workpiece grinding and the turnery processing of various band internal spline.
[accompanying drawing explanation]
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only It is embodiments more of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure, 1, clamp body, 2, clamping sleeve, 3, clamp nut, 4, workpiece.
[detailed description of the invention]
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise The every other embodiment obtained, broadly falls into the scope of this utility model protection.
With reference to Fig. 1, a kind of positioning clamping device, including clamp body 1, clamping sleeve 2 and clamp nut 3, clamp body 1 is for being provided with The Step Shaft of external splines, described fixture, the surface, external splines big footpath of 1 is cone shape, its large and small end diameter and workpiece internal spline Large and small footpath size is suitable, described cone outside diameter is slightly larger than workpiece 4 internal spline big footpath size, and end diameter is slightly less than Workpiece 4 internal spline big footpath size.
Described clamping sleeve 2 is positioned at the middle part of clamp body 1, and it is the cone of hollow, outside clamping sleeve 2 endoporus is with clamp body 1 Circle is matched in clearance, it is ensured that the axiality requirement of processing.The surface of clamping sleeve 2 is provided with external splines, its large and small end diameter and work Part 4 internal spline large and small footpath size is suitable.Described external splines outside diameter is slightly larger than workpiece 4 internal spline big footpath size, and small end is straight Footpath is slightly less than workpiece 4 internal spline big footpath size.
Clamp nut 3 is connected with the male end of described clamp body 1, the most adjacent with clamping sleeve 2, presses workpiece 4 together Tightening position.
During use, tighten clamp nut 3 and can make described clamp body 1 and the clamping sleeve 2 external splines big footpath conical surface and flower in workpiece 4 Fitting in surface, key big footpath, thus realizes the clamping to workpiece 4 and location.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in this utility model Protection domain within.
