Abstract
The utility model discloses a movable center mechanism of a gear grinding machine, which comprises a center sliding seat and a center. An end cap is fixed on the top portion of the center sliding seat, and a guide post and the center which are capable of moving up and down, and a fastening screw sleeve and a pull nail which are used for connecting the guide post and the center are arranged inside the center sliding seat. A guide sleeve and a spring are sequentially disposed on the outer side of the guide post, the fastening screw sleeve is mounted on the lower side of the guide post, the center is arranged on the lower side of the fastening screw sleeve, the pull nail is disposed on the upper side inside of the fastening screw sleeve, and the center is mounted on the lower side of the pull nail. The mechanism has the advantages of reasonable structure, simple manufacturing technique, capability of retaining correct positioning due to the fact that after conical surface positioning of the center, the pull nail can further position the center and the center can perform fine adjustment on the centre of the center, low production cost and convenience in popularization and utilization.
Description
Technical field
The utility model belongs to the Machining Technology field, relates to a kind of machine tool accessories, is specifically related to a kind of gear grinding machines rolling center mechanism.
Background technology
At present, lathe tip mechanism commonly used is assembling one a cover centripetal force bearing and a cover thrust bearing in top, and the centripetal force bearing is used to support top rotation, and thrust bearing is used for bearing the axial force of the top work of lathe.The top precision of this type of lathe mainly relies on bearing, the top and machining accuracy of top main body and three's reasonable assembling thereof to guarantee, because it is many to influence the top factors of accuracy of lathe, rigging error is big, so positioning accuracy is poor.Chang Yong lathe tip mechanism can not be adjusted top center after finish the location in addition.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of gear grinding machines rolling center mechanism is provided, and it is rational in infrastructure, manufacturing process is simple, positioning accuracy is high, production cost is low, is convenient to promote the use of.
For achieving the above object, the technical solution adopted in the utility model is: a kind of gear grinding machines rolling center mechanism, comprise top slide and top, it is characterized in that: described top slide top is fixed with end cap, top slide inside is provided with lead moving up and down and top, and be used to connect lead and top jackscrew cover and blind rivet, the described lead outside is disposed with guide pin bushing and spring, the lead below is equipped with the jackscrew cover, described jackscrew cover downside is provided with jackscrew, jackscrew cover upper inside is provided with blind rivet, and this blind rivet downside is equipped with top.
Described jackscrew cover arranged outside has lining, and this lining is connected by screw thread with top slide.
The quantity of described jackscrew is 2-8.
Described end cap is connected by screw with top slide.
Described blind rivet is connected by screw thread with top.
Described jackscrew is connected by screw thread with the jackscrew cover.
The utility model compared with prior art has the following advantages:
(1) rational in infrastructure, production technology is simple.This gear grinding machines helical angle pneuma-lock mechanism structure is reasonable, and production technology is simple;
(2) positioning accuracy height.Behind this gear grinding machines rolling center mechanism conical surface location, blind rivet can further be located top, and jackscrew can be finely tuned top center, can keep accurate in locating;
(3) production cost low, be convenient to promote the use of.A lot of parts of this gear grinding machines rolling center mechanism all are easy to produce, buy, thereby its production cost is very low, is convenient to promote the use of.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
