Description
Technical field
A kind of gear teeth frock is the utility model is related to, relates generally to gear hobbing process field.
Background technology
Gear in motorcycle engine, these gears require very high to tooth form teeth directional and tooth runout, due to former material
Material is all than relatively thin, if single progress gear hobbing, it may appear that the axiality of each gear is very low, while change is easily produced in process
Shape, therefore using the gear hobbing tooling in common Gear Processing, in order to improve axiality and bulk strength, generally by multiple former materials
Material is connected on a mandrel, is then disposably carried out gear hobbing, is carried out gear hobbing in this way, can produce series of malpractice,
It is bigger with respect to the length of mandrel and contacts baseplate to be primarily due to install the length of workpiece on mandrel, therefore can workpiece in hobbing process
There is the phenomenon rocked together with mandrel, while multiple workpiece are arranged on mandrel, increase coefficient of friction, and it is tired to produce dismounting
Difficult phenomenon, reduces gear hobbing efficiency.
Utility model content
For above the deficiencies in the prior art, the utility model proposes a kind of gear teeth frock of convenient dismounting.
To reach above-mentioned purpose, the technical solution of the utility model is：Including fixed seat and mandrel, fixed seat is one horizontal
The fixing axle of setting, the left end of the fixing axle is cylindrical to be provided with bottom plate, is axially arranged with through hole in the fixing axle, and the through hole is the left small right side
Big shoulder hole, mandrel matching are interference fitted in through hole with the aperture portion of shoulder hole, and the mandrel is extended right up to outside hole,
Mandrel right-hand member closing panel, screw thread is combined with nut on the mandrel on the right side of cover plate, the mandrel inside the macroperforation of shoulder hole
Upper axial direction is equipped with bullet pin, and bullet pin is extended by the spring being enclosed on outside left side on mandrel to outside through hole.
Technical principle of the present utility model is as follows：When gear hobbing, the multiple workpiece of workpiece are extended to admittedly installed in mandrel
Part outside reservation, cover plate is then covered into right-hand member in workpiece by mandrel, workpiece is locked on mandrel by nut.
When being fitted without workpiece, bullet pin under the action of the spring will be to when extending outside through hole, therefore install workpiece, bullet pin
Its axial compressive force, spring-compressed, bullet pin are moved to inside through hole by workpiece, after gear hobbing is completed, nut is pulled down, does not have
After the fixation of nut, under the action of the spring, workpiece will be ejected bullet pin from mandrel, and then improve the dismounting speed of workpiece
Degree.
The beneficial effects of the utility model are as follows：When workpiece is arranged on mandrel, bullet pin is pressed into by workpiece
In shoulder hole, then by nut, workpiece is fixed so that workpiece will not bullet goes down from mandrel by spring.Simultaneously because
Bullet pin axially is mounted with inside fixing axle, therefore when gear hobbing is completed, removes nut, has lacked consolidating to workpiece for nut
Fixed, workpiece will be ejected by bullet pin, and workpiece comes off from mandrel.Therefore, when gear hobbing terminates, can quickly realize to workpiece
Dismounting, improve the overall efficiency of work pieces process.Mandrel is interference fitted in fixed seat, and fixed seat is a fixing axle, because
This compares fixed workpiece portion, the length increase that mandrel is fixed, improves the bulk strength of mandrel fixation, prevents mandrel from arbitrarily shaking
It is dynamic.Improve the accuracy of gear hobbing process.
Further, bullet pin is the cylinder being enclosed on outside on mandrel, by the way of cylinder, improves the globality of bullet pin.
Further, the left end of mandrel is provided with end cap, and mandrel is coordinated and positioned in hole.
Further, mandrel is multi-diameter shaft, and the part extended right up to outside through hole is thin axle, is that workpiece is convenient on multi-diameter shaft
Positioning.

Embodiment
Below in conjunction with accompanying drawing, the technical scheme in the utility model is clearly and completely described, it is clear that retouched
The embodiment stated is only preferred embodiment of the present utility model, rather than whole embodiments.Based in the utility model
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, all
Belong to the scope of the utility model protection.
Embodiment
As shown in Figure 1：
The utility model embodiment includes fixed seat 1 and mandrel 3.
The fixed seat 1 is horizontally disposed fixing axle, and the fixing axle is axially arranged with through hole, and the through hole is arranged to shoulder hole,
Right-hand member for macropore, left end for aperture, interference fit has mandrel 3 in aperture.
On mandrel 3 on the outside of through hole left end be provided with end cap, position of the mandrel 3 in through hole is positioned, mandrel 3 to
The right side is extended to outside through hole, is combined with cover plate 6 in the right-hand member of mandrel 3, the right-hand member end thread of mandrel 3 is combined with nut 7, and workpiece 5 is pacified
On mandrel 3 outside through hole, outer on the mandrel 3 of macropore inside the shoulder hole to be cased with columnar bullet pin 4, the bullet pin 4 exists
Spring 2 of the through hole internal engagement on mandrel 3 is extended to outside through hole under acting on.
Bottom plate is provided with fixing axle left end, is fixed on by the screwed hole on bottom plate in frame.
