Abstract
The invention discloses one kind to be inserted radially into formula internal spline broaching fixture, and it is made up of pedestal, limited block and bolt.The limited block is disposed upon the semicircle ring set on pedestal end face, openend both sides are provided with the leg radially outward stretched out, one side for leg towards the pedestal of run through bolt 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 limited block is bolted pedestal, forms the positioning broaching fixture structure that formula is inserted radially into for workpiece.The outlet structure of this scale, in workpiece insertion process, there is the qualitative screening effect of axial dimension and remove to adhere to impurity on workpiece surface.Due to the faying face of workpiece and fixture before positioning it is automatically clean, be advantageous to improve positioning precision and machining accuracy.
Description
Technical field
The present invention relates to a kind of component of machine machining fixture, in particular it relates to which a kind of internal spline is broached
Fixture, particularly one kind are inserted radially into formula internal spline broaching fixture.
Background technology
During common workpiece wire pulling method, broaching fixture is generally used as axial limiting benchmark, workpiece using the end face that workpiece mutually leans on
Endoporus positions with broaching tool coaxial cooperation.Such a positioning broaching is simple in construction, installation is easy, broaching efficiency high, can reach pre-
Precision and the size requirement of phase.But this face-to-face positioning datum precision is easily influenceed by faying face cleanliness factor, as long as a side
Chip class impurity is remained on end face, workpiece positioning precision 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 prior art
End face is freely docked, and the workpiece axial dimension that this structure treats broaching is unrestricted, and some axial dimensions are overproof during use or end face
The overproof workpiece of perpendicularity, it is also accessible to flow among broaching process, easily cause unnecessary material, equipment and artificial aspect
The wasting of resources.
The content of the invention
Present invention is generally directed to the deficiencies in the prior art, propose that one kind is simple in construction, easy to use, workpiece has when installing
Self-cleaning action, and that makees qualitative screening to workpiece axial dimension is inserted radially into formula internal spline broaching fixture.
The present invention is achieved through the following technical solutions technical goal.
Formula internal spline broaching fixture is inserted radially into, it is made up 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 provided with the leg that radially outward stretches out, and the leg for run through bolt is 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~
0.15mm deviations, limited block are bolted pedestal, form 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 present invention 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, could realize installation
And positioning, this simple in construction, install convenient, accurate positioning；
2nd, after the limited block to match with pedestal is installed in place, because open trough width dimensions are fixed, it is also axle that workpiece, which assigns process,
To the process of the qualitative screening of size, 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, such a only to stay between cooperation
The insert structure of gap, during insertion, it is easy to attached debris on the surface of the workpiece being stripped off mechanicalness, before faying face positioning
It is clean.Be advantageous to improve positioning precision and machining accuracy.
Brief description of the drawings
Fig. 1 is the diagrammatic cross-section of the present invention.
Fig. 2 is Fig. 1 top view.
Embodiment
Below according to accompanying drawing and in conjunction with the embodiments, the invention will be further described.
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 up of pedestal 1, limited block 2 and bolt 3.Property component based on the pedestal 1, 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 the end face of pedestal 1
Shape component, the openend both sides of this semicircle ring set are respectively equipped with the leg radially outward stretched out, the branch for run through bolt 3
The one side of pin 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, and 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 that the Inner arc R centers of circle of limited block 2 and the axial technique through hole of pedestal 1 are coaxial in structure.This is simple in construction, installation is easy, fixed
Level is true, can accomplish that workpiece is inserted radially into and is accurately positioned in place with regard to realizing, you can into the broaching process of internal spline.
The supporting height of shoulder H sizes of limited block 2 of pedestal 1 are identical with workpiece teeth portion thickness nominal dimension in the present invention, this
Kind only stays the plug-in type of fit clearance to position broaching structure, is easy to attached debris on the surface of the workpiece during insertion by machine
Tool scrapes, due to the faying face of workpiece and fixture before positioning it is automatically clean, be advantageous to improve positioning precision and processing
Precision.In addition, the outlet structure of this scale in workpiece insertion process, has the qualitative screening effect of axial dimension, can avoided
The overproof workpiece of axial dimension is also broached and produces the unnecessary wasting of resources by mistake.
