Description
Technical field
The utility model relates to tooth shaft fixture technology fields.
Background technique
It processes to obtain the tooth form of gear part by gear hobbing or roll flute, to be finished toward contact.Roll flute processing is main
Finishing for quenching hard gear.Since roll flute can correct every error of gear preprocessing, thus machining accuracy is higher.Mill
Precision is generally up to 6 grades or more after tooth.
It would generally be related to roll flute processing in the process of tooth shaft, and it is logical about the roll flute processing of tooth shaft in the prior art
It is often to be fixed on tooth shaft workpiece on gear grinding machines by fixture to process, and fixture in the prior art is usually three-jaw card
Disk, scroll chuck are the fixed mode of outer circle, and this fixed form is relatively simple and bad to neutrality, is easy to influence tooth shaft
Processing quality.
Utility model content
The purpose of this utility model is to provide a kind of tooth shaft gear grinding clamps, are easy to influence to solve fixture in the prior art
The problem of processing quality of tooth shaft.
In order to achieve the above object, the base case of the utility model provides a kind of tooth shaft gear grinding clamp, including along axial direction
Mandrel, elastic jacket, locking nut and the tapered sleeve that from-inner-to-outer is set gradually, wherein mandrel include along axial direction from outer to inner according to
Secondary distribution is used for the top of top tight workpiece, boss, the cylindrical portion for being gripped with lathe bed and conical section, elasticity
Collet be set in it is top upper and with top fixation, the outer end of elastic jacket outer wall is in cone cell, and the inner end of elastic jacket outer wall is set
There is external thread section, elastic jacket is circumferentially provided with several dilatation joints, and rubber seal is fixed in dilatation joint, and locking nut screw thread connects
Connect on external thread section, the outer end of tapered sleeve inner cavity outer end and elastic jacket outer wall matches and in reaming shape, tapered sleeve inner end then with
Locking nut offsets.
The beneficial effect of this base case is:
When work, the anodontia end of workpiece is protruded into elastic jacket, until workpiece end offsets with top top, at this time
Locking nut is rotated in the forward direction, locking nut slides axially outward and tapered sleeve is driven to slide in and out, and tapered sleeve outer end constantly squeezes bullet
Property collet outer end so pass through top centering abutting, elastic jacket clamps so that elastic jacket be made inwardly to tighten Workpiece clamping
Mode realize comprehensive fixation of workpiece, it is convenient and efficient effectively.
In whole process, rubber seal can be always filled dilatation joint, thus the clast for avoiding processing from generating
It is entered in elastic jacket inner cavity during dilatation joint is opened, retracted, tooth shaft workpiece is caused to damage or influence elastic clip
The normal opening or retraction of set.The setting of conical section is so that mandrel is easier in when fixing on gear grinding machines, and cylindrical portion is then
Mandrel is facilitated to be clamped and fixed on gear grinding machines.
The fixture of the utility model is ingenious in design, accurate positioning and easy to use, also avoid fixture influence tooth shaft plus
Working medium amount.
Further, top, boss, cylindrical portion and conical section are integrally formed.So set, not only whole machining accuracy
It can be effectively ensured, and the stability connected also greatly enhances.
Further, locking nut periphery is equipped with several teeth.So set, facilitate using tool and tooth cooperation after to locking screw
Mother screws.
Further, rubber seal is corrugated or V-arrangement is arranged.It is close that rubber seal such setting can enhance rubber
The ability of sealing opened or shunk with dilatation joint at every moment guarantees that the clast for generating processing passes through dilatation joint
It enters in elastic jacket inner cavity.
Further, top is clearance fit between elastic jacket.So set, not only the cooperation precision of the two is high, and
And it firmly installs.
Detailed description of the invention
Fig. 1 is a kind of main view of tooth shaft gear grinding clamp embodiment of the utility model.
Specific embodiment
Below by the further details of explanation of specific embodiment:
Appended drawing reference in Figure of description includes: elastic jacket 1, tapered sleeve 2, locking nut 3, mandrel 4.
As shown in Figure 1, a kind of tooth shaft gear grinding clamp, including mandrel 4, the elastic clip set gradually along axial from-inner-to-outer
Set, locking nut 3 and tapered sleeve 2, wherein mandrel 4 includes the top for top tight workpiece being sequentially distributed from outer to inner along axial direction
Point, boss, the cylindrical portion for being gripped with lathe bed and conical section, elastic jacket be set in it is top upper and with it is top
Fixed, the outer end of elastic jacket outer wall is in cone cell, and equipped with external thread section, elastic jacket is circumferentially opened for the inner end of elastic jacket outer wall
There are several dilatation joints, rubber seal is fixed in dilatation joint, locking nut 3 is threaded on external thread section, 2 inner cavity of tapered sleeve
Outer end and the outer end of elastic jacket outer wall match and in reaming shapes, and 2 inner end of tapered sleeve then offsets with locking nut 3.
Top, boss, cylindrical portion and conical section are integrally formed.So set, not only whole machining accuracy can obtain
To being effectively ensured, and the stability connected also greatly enhances.3 periphery of locking nut is equipped with several teeth.So set, facilitating benefit
Locking nut 3 is screwed after being cooperated with tool and tooth.Rubber seal is corrugated or V-arrangement is arranged.Rubber seal
The ability opened or shunk with dilatation joint that can enhance rubber seal is arranged such, at every moment guarantees not make to add
The clast that work generates is entered in elastic jacket inner cavity by dilatation joint.Top is clearance fit between elastic jacket.So
Setting, not only the cooperation precision of the two is high, but also firmly installs.The setting of conical section so that mandrel when being fixed on gear grinding machines more
It is easy centering, cylindrical portion then facilitates mandrel to be clamped and fixed on gear grinding machines.
When work, the anodontia end of workpiece is protruded into elastic jacket, until workpiece end offsets with top top, at this time
Locking nut 3 is rotated in the forward direction, locking nut 3 slides axially outward and tapered sleeve 2 is driven to slide in and out, and 2 outer end of tapered sleeve is constantly squeezed
Compression elasticity collet outer end so passes through top centering abutting, elastic jacket so that elastic jacket be made inwardly to tighten Workpiece clamping
The mode of clamping realizes comprehensive fixation of workpiece, convenient and efficient effective.
In whole process, rubber seal can be always filled dilatation joint, thus the clast for avoiding processing from generating
It is entered in elastic jacket inner cavity during dilatation joint is opened, retracted, tooth shaft workpiece is caused to damage or influence elastic clip
The normal opening or retraction of set.
Above-described is only the embodiments of the present invention, and the common sense such as well known specific structure and characteristic are herein in scheme
It does not describe excessively.It should be pointed out that for those skilled in the art, in the premise for not departing from the utility model structure
