Description
Technical field
The present invention relates to a kind of gear rolling machine, specifically a kind of tip mechanism of gear rolling machine.
Background technology
As involute spline has been used more and more generally in automobile industry, gear rolling machine is processed in involute spline and led
The application in domain is more and more, and gear rolling machine has progressively captured involute with advantages such as converted products precision height, efficiency high, cost performance height
The field of processing industry.But the popularization and popularization used with involute spline, for involute spline processing requirement and
Dimensional accuracy is also with regard to more and more higher, and difficulty of processing is also increasing.At present, the tip mechanism of gear rolling machine be generally linear guides with
Tailstock is combined, top to be placed in tailstock, when starting processing, is stopped when linear guides are run at limit switch, now
The top product that withstands is processed, but is caused because the center hole of product is not of uniform size, it is easy to cause product during initial adjustment to be
In clamped condition, but remaining product is releasing orientation, when rolling product can before and after play, now can be to the involute of product
The size and precision of spline cause influence, it is impossible to ensure the quality and performance of the Continuous maching of product, the use band to product
Carry out hidden danger.
The content of the invention
Processing continuity is ensure that it is an object of the invention to provide one kind, is not had on Product Precision and quality influential
The tip mechanism of gear rolling machine.
Improvement of the invention primarily directed to existing gear rolling machine apex tailstock part, concrete technical scheme is as follows：
Top to be arranged on tailstock the invention mainly comprises having tailstock and top, present invention additionally comprises have tailstock sleeve, drawing
Tailstock sleeve is set in bar, the first spring, second spring and end cap, the wherein axial center hole of tailstock, the tailstock sleeve
Axial forward end stretches out the centre bore of tailstock, and the rear portion of the axial center hole of the tailstock sets end cap, and end cap is by tailstock back-end closure；
The axial center hole of the tailstock sleeve is reducing hole, and the reducing hole is diameter by substantially small three sections, i.e., preceding sector hole, middle sector hole
And rear sector hole, the axial forward end portion of tailstock sleeve sets top, and top bar portion connects with the preceding sector hole of tailstock sleeve, top
The preceding sector hole of tailstock sleeve is stretched out in tip；A pull bar is stretched into tailstock sleeve from the axial centre position of above-mentioned end cap, should
There is a diameter to be more than the leading portion bore dia of tailstock sleeve and be less than the stage casing bore dia of tailstock sleeve for the front end of pull bar
Round platform, the front end face of the round platform is withstood on before the middle sector hole of tailstock sleeve on hole wall；Two springs, i.e., first are socketed on the pull bar
Spring and second spring, wherein the external diameter of the first spring is less than the stage casing bore dia of tailstock sleeve, the front end of the first spring is withstood on
On the rear end face of above-mentioned round platform, the rear end of the first spring is withstood on the front end face of above-mentioned end cap；The external diameter of the second spring is big
Stage casing bore dia in tailstock sleeve and the back segment bore dia less than tailstock sleeve, the front end of second spring is withstood on before rear sector hole
On hole wall, the rear end of second spring is withstood on the front end face of above-mentioned end cap；The pull bar sets pull-rod nut close to end position thereafter.
As the preferred scheme of the present invention, set and set on the keyway of bar shaped, tailstock on the periphery wall of the tailstock sleeve
End extends the alignment pin in the keyway, to realize to the spacing of abutment sleeve position and adjustment.
The present invention work approximately as：
During off working state, the first spring and second spring are in compressive state, and during working condition, tailstock is by servomotor
Drive and move forward, the first spring and second spring are further compressed, and are moved rearwards by pull bar, limited location is opened after pull bar
Close, when the pull-rod nut on gear rolling machine tailstock pull bar touches limit switch, give lathe enabling signal, now lathe starts to add
Work；After completion of processing, servomotor drives tailstock to retreat, and spring and spring give gear rolling machine tailstock sleeve and gear rolling tail respectively
Seat pull bar elastic force, makes top to reset.
The present invention has the following advantages that compared with prior art：
1st, do not interfere with product steps up state, it is ensured that the processing of the stability of product and spline is stable during rolling；
2nd, ensure the continuity of processing, do not interfere with the quality and precision of product；
3rd, simple structure, it is easy to operate；
4th, factory process efficiency is improved, operating cost is reduced.
