Abstract
The utility model discloses one kind to be inserted radially into formula internal spline broaching fixture, it is made of pedestal, limited block and bolt.The limited block is disposed upon the semicircle ring set on pedestal end face, openend both sides are equipped with the leg radially outward stretched out, one side for the leg through bolt towards pedestal is shoulder structure, reserved height of shoulder H sizes are equal with workpiece teeth portion thickness nominal dimension, only allow have 0.05~0.15mm deviations.The semicircle internal bore radius R of limited block is bigger 0.1~0.2mm than workpiece positioning shaft part radius, and pedestal is bolted in limited block, forms the positioning broaching fixture structure that formula is inserted radially into for workpiece.The outlet structure of this scale, in workpiece insertion process, has the function that the qualitative screening effect of axial dimension and removes to adhere to impurity on workpiece surface.Due to the faying face of workpiece and fixture before positioning it is automatically clean, be conducive to improve positioning accuracy and machining accuracy.
Description
Technical field
A kind of component of machine machining fixture is the utility model is related to, specifically, the utility model is related in one kind
Spline broaching fixture, particularly one kind are inserted radially into formula internal spline broaching fixture.
Background technology
During common workpiece wire pulling method, broaching fixture is usually used as axial limiting benchmark, workpiece using the end face that workpiece mutually leans on
Endoporus is positioned with broaching tool coaxial cooperation.Such a positioning broaching is simple in structure, installation is easy, broaching is efficient, can reach pre-
Precision and the size requirement of phase.But this face-to-face positioning datum precision is easily influenced by faying face cleanliness factor, as long as a side
Chip class impurity is remained on end face, workpiece positioning accuracy is necessarily reduced after installation, so as to influence the product quality of broaching workpiece, gently
Workpiece end face is then caused to have impression defect, site error that is heavy then causing workpiece.In addition, the broaching fixture and workpiece of the prior art
End face is freely docked, and the workpiece axial dimension that this structure treats broaching is unrestricted, some axial dimensions are overproof during use or end face
The overproof workpiece of verticality, it is also accessible to flow among broaching process, easily cause unnecessary material, equipment and artificial aspect
The wasting of resources.
Utility model content
The utility model proposes that one kind is simple in structure, easy to use, when workpiece is installed mainly for the deficiencies in the prior art
With self-cleaning action, and that makees qualitative screening to workpiece axial dimension is inserted radially into formula internal spline broaching fixture.
The utility model is achieved through the following technical solutions technical goal.
Formula internal spline broaching fixture is inserted radially into, it is made of pedestal, limited block and bolt.The pedestal is one piece of circle
Ring flange, centre are reserved for the axial technique through hole that broaching tool passes through.It is theed improvement is that：The limited block is disposed upon pedestal
Semicircle ring set on end face, openend both sides are equipped with the leg that radially outward stretches out, for the leg through bolt towards seat
The one side of body is shoulder structure, and it is equal with workpiece teeth portion thickness nominal dimension to reserve height of shoulder H sizes, only allow to have 0.05~
Pedestal is bolted in 0.15mm deviations, limited block, forms the positioning broaching fixture structure that formula is inserted radially into for workpiece.
As further improvement project, the limited block both sides leg bottom surface is parallel to each other with shoulder inner plane, parallel mistake
Difference is less than 0.01mm.
As further improvement project, the Inner arc R centers of circle of the limited block and the axial technique through hole of pedestal are coaxial.
The utility model compared with prior art, has the positive effect that：
1st, after the limited block to match with pedestal is installed in place, slot structure is formed, workpiece, which is only inserted radially into, to be realized
It is fixed and positioned, this simple in structure, install convenient, accurate positioning；
2nd, after the limited block to match with pedestal is installed in place, because open trough width dimensions are fixed, workpiece assigns process
It is the process of the qualitative screening of axial dimension, the overproof workpiece of axial dimension can be avoided also to be broached by mistake and produce the wasting of resources；
3rd, the supporting limited block height of shoulder H sizes of pedestal are identical with workpiece teeth portion thickness nominal dimension, and such a only stay is matched somebody with somebody
The insert structure in gap is closed, during insertion, easy to which attached debris on the surface of the workpiece is stripped off mechanicalness, faying face is fixed
It is clean before position.Be conducive to improve positioning accuracy and machining accuracy.
Brief description of the drawings
Fig. 1 is the diagrammatic cross-section of the utility model.
Fig. 2 is the top view of Fig. 1.
Embodiment
Below according to attached drawing and in conjunction with the embodiments, the utility model is described in further detail.
Formula internal spline broaching fixture is inserted radially into shown in Fig. 1, is saloon car transmission shifting gear internal spline broaching fixture
Embodiment schematic diagram, it is made of pedestal 1, limited block 2 and bolt 3.The pedestal 1 is basis property component, it is one piece of circle
Shape ring flange, centre are reserved for the axial fabrication hole that broaching tool passes through.The limited block 2 is disposed upon different on 1 end face of pedestal
Shape component, the openend both sides of this semicircle ring set are respectively equipped with the leg radially outward stretched out, for the branch through bolt 3
The one side of foot towards pedestal 1 is shoulder structure, and reserved height of shoulder H sizes are equal with workpiece teeth portion thickness nominal dimension, only allow
There are 0.05~0.15mm deviations, the present embodiment reserves platform because shifting gear specification is smaller, by the nominal dimension of workpiece teeth portion thickness
Shoulder height degree H sizes, the deviation of H sizes is in the range of 0.05~0.08mm.Limited block 2 is the auxiliary equipment of pedestal 1, both use bolt
3 connect into a kind of positioning broaching structure that formula is inserted radially into for workpiece.It can be accurately positioned after being inserted radially into order to ensure workpiece,
Require the 2 Inner arc R centers of circle of limited block and the axial technique through hole of pedestal 1 coaxial in structure.This is simple in structure, installation is easy, fixed
Level is true, can accomplish that workpiece is inserted radially into and just realize accurate positionin in place, you can into the broaching process of internal spline.
The supporting 2 height of shoulder H sizes of limited block of pedestal 1 and workpiece teeth portion thickness nominal dimension phase in the utility model
Together, such a plug-in type for only staying fit clearance positions broaching structure, is easy to attached on the surface of the workpiece miscellaneous during insertion
Thing is scraped by mechanicalness, due to the faying face of workpiece and fixture before positioning it is automatically clean, be conducive to improve positioning accuracy
And machining accuracy.In addition, the outlet structure of this scale in workpiece insertion process, has the qualitative screening effect of axial dimension,
The overproof workpiece of axial dimension can be avoided also to be broached by mistake and produce the unnecessary wasting of resources.
