Abstract

The utility model discloses the two eccentric fixture of a kind of high accuracy, comprise the axle journal seat and eccentric bushing that are separately positioned on axle journal two ends, described eccentric bushing is provided with datum plane and some groups for inserting top two eccentric orfices, and described datum plane is arranged on the periphery of eccentric bushing; Described eccentric bushing is arranged in the endoporus of axle journal seat; This pair of eccentric fixture structure is simple, makes and easy to use, with low cost, and eccentric precision is high, is applicable to the part that processing eccentric throw is less.

Description

The two eccentric fixture of high accuracy
Technical field
The utility model belongs to field of fixtures, is specifically related to the two eccentric fixture of a kind of high accuracy.
Background technology
On axle, machining high-precision is eccentric adopts two kinds of methods usually: one adopts cam grainder to carry out grinding.The method need by means of special purpose machine tool, and not only cost drops into higher, and the deviation from circular from processed is more than 0.03mm, and machining accuracy is poor.Another kind directly on axle, processes eccentric centre bore, then carries out grinding at cylindrical grinder.The method needs the eccentric centre bore of work pieces process one by one, and production efficiency is lower, and eccentric throw uniformity is more than 0.02mm, though machining accuracy is a little more than first method, but still cannot meet the process requirements of high accuracy bias, and is not suitable for processing the less part of eccentric throw.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of and can effectively enhances productivity and the two eccentric fixture of high accuracy of machining accuracy.
For achieving the above object, the utility model provides following technical scheme: the two eccentric fixture of a kind of high accuracy, comprise the axle journal seat and eccentric bushing that are separately positioned on axle journal two ends, described eccentric bushing is provided with datum plane and some groups for inserting top two eccentric orfices, and described datum plane is arranged on the periphery of eccentric bushing; Described eccentric bushing is arranged in the endoporus of axle journal seat.
Further, the endoporus of described axle journal seat is tapered hole.
The beneficial effects of the utility model are: this pair of eccentric fixture structure is simple, make and easy to use, safeguard simple and easy, with low cost; Be not only applicable to two eccentric processing, be also applicable to the eccentric processing of different size simultaneously; On eccentric bushing, eccentric orfice time processing is shaping, and efficiently solve and utilize universal machine tools to process two eccentric eccentric throw problem produced, part eccentric throw error is little, and uniformity precision is good, and production efficiency is high, is applicable to the part that processing eccentric throw is less.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly, the utility model provides following accompanying drawing to be described:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of eccentric bushing.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, 2, the two eccentric fixture of high accuracy of the present embodiment, comprise the axle journal seat 2 and eccentric bushing 3 that are separately positioned on axle journal 1 two ends, described eccentric bushing 3 is provided with a datum plane 31 and one group for inserting top two eccentric orfices 32, and described datum plane 31 is arranged on the periphery of eccentric bushing 3; Described eccentric bushing 3 is arranged in the endoporus of axle journal seat 2.
In the present embodiment, eccentric bushing 3 is only provided with one group of two eccentric orfice 32, and holes is symmetrical about the center of circle, during processing eccentric work piece, eccentric bushing 3 is arranged in axle journal seat 2, the more two eccentric fixtures assembled are fastened on the axle journal 1 at workpiece two ends respectively, top correspondence is withstood in the eccentric orfice 32 at workpiece two ends, rotary cutting workpiece can obtain eccentric work piece, and the eccentric throw of eccentric work piece is determined by eccentric orfice 32 on eccentric bushing 3 and the distance between eccentric bushing 3 center of circle.In addition, during fastening pair of eccentric fixture, should first carry out levelling to the datum plane 31 on two ends, workpiece left and right eccentric bushing 3, ensure that the position of eccentric bushing 3 aligns.Certainly, the two eccentric orfice 32 of many groups also can be set according to the actual requirements, to meet the eccentric work piece process requirements of different distance.
As the further improvement of such scheme, the endoporus of described axle journal seat 2 is tapered hole, can improve the quality of fit between eccentric mounting and workpiece axle journal 1.
What finally illustrate is, above preferred embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model by above preferred embodiment, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from the utility model claims limited range.
