Description

The heavy caliber cylinder combination is rolled boring head
Technical field:
The utility model relates to machining tool manufacturing technology field, and especially a kind of heavy caliber cylinder combination is rolled boring head.
Background technology:
When processing jack heavy caliber cylinder barrel at present, need four procedures such as heavy boring, right boring, floating cutter, honing, processed complex, the production cycle is long, and is time-consuming.
The utility model content:
The purpose of this utility model provides a kind of heavy caliber cylinder combination and rolls boring head, can simplify manufacturing procedure.
The technical solution of the utility model is: described a kind of heavy caliber cylinder combination is rolled boring head, the front-end of spindle that rolls boring head in its combination is equipped with knife rest, boring cutter is housed on the knife rest, ball cover plate, retainer, bracket, bearing block are housed on main shaft successively, adapter sleeve is housed in the rear end of main shaft; Bearing is housed on bearing block, and cylinder ball before being equipped with on the front of retainer is equipped with back cylinder ball on the rear of retainer.
The other end at described adapter sleeve is provided with screwed hole.
The rear end of described main shaft is threaded with adapter sleeve.
The utility model can be merged into a procedure with above-mentioned back three process, with once success of right boring, roll extrusion, rolls the boring head dedicated tool by the combination after the transformation of the way and not only can guarantee its precision and physical dimension, also can simplify manufacturing procedure, saves processing cost.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
As shown in fig. 1, front end at main shaft 11 of the present utility model is equipped with knife rest 2, boring cutter 3 is housed on the knife rest 2, ball cover plate 1, retainer 5, bracket 7, bearing block 9 are housed on main shaft 11 successively, in the rear end of main shaft 11 adapter sleeve 10 is housed, the rear end of main shaft 11 is threaded with adapter sleeve 10, and the other end of adapter sleeve 10 is provided with screwed hole, and the other end of adapter sleeve 10 is threaded with the boring bar of boring machine; Bearing 8 is housed on bearing block 9, four preceding cylinder balls 4 are housed on the front of retainer 5, cylinder ball 6 after being equipped with eight on the rear of retainer 5, ball cover plate 1 and bracket 7 can block preceding cylinder ball 4, back cylinder ball 6 does not come off.
During processing jack heavy caliber cylinder barrel, carry out heavy boring earlier, re-use the utility model and carry out right boring, roll extrusion, not only can guarantee the right boring dimensional accuracy, also can simplify manufacturing procedure, save processing cost.
