Utility model content:
The purpose of this utility model is just the centre head providing a kind of grinding work-piece inner hole cone wall, mechanism is simple, production cost is low and easy to use feature that it has.
For achieving the above object, the centre head of a kind of grinding work-piece inner hole cone wall of the present utility model comprises top body, it also comprises conical sleeve, the front end of described top body has nose cone, the wall of described conical sleeve offers some mounting grooves, rollably be provided with needle roller in described mounting groove, described conical sleeve to be placed on nose cone and to be locked by securing member, and the periphery of described needle roller contacts with described cone headed taper seat.
Preferred as technique scheme, the rearward end of described top body is the taper shank portion matched with tailstock tool, and rear end, described taper shank portion forms located block.
Preferred as technique scheme, the front end of described top body is top head, and described top head is made up of cylindrical section and nose cone, and described cylindrical section is connected with cone headed stub end.
Preferred as technique scheme, described top body is positioned at described cylindrical section rear end and forms thread segment, and the rear end of described thread segment is be molded over the locating stop piece on top body.
Preferred as technique scheme, described cylindrical section is provided with end face bearing, an end face of described end face bearing is pressed against on the end face of thread segment, the end contact of the stub end of other end and conical sleeve, and described securing member is screwed onto thread segment.
Preferred as technique scheme, described securing member is locking nut.
Preferred as technique scheme, the position being positioned at described locating stop piece rear forms anti-slip part to described top body.
Preferred as technique scheme, described anti-slip part is at the shaping anti-slip tank of the circumferential surface of top body.
The beneficial effects of the utility model are: the utility model has the advantages that mechanism is simple, production cost is low and easy to use, and in addition, the utility model can also improve working (machining) efficiency, can save time, laborsaving.

In figure: 1, top body; 2, end face bearing; 3, conical sleeve; 4, needle roller; 5, securing member; 11, taper shank portion; 12, located block; 13, anti-slip part; 14, locating stop piece; 15, nose cone; 16, cylindrical section; 17, top head; 18, thread segment; 31, mounting groove
Detailed description of the invention:
The following stated is only the preferred embodiment embodying the utility model principle, does not therefore limit protection domain of the present utility model
Be the embodiment of the centre head of a kind of grinding work-piece inner hole cone of the utility model wall as shown in Figures 1 to 3, it comprises top body 1, it also comprises conical sleeve 3, the front end of described top body 1 has nose cone 15, the wall of described conical sleeve 3 offers some mounting grooves 31, rollably be provided with needle roller 4 in described mounting groove 31, described conical sleeve 3 to be placed on nose cone 15 and to be locked by securing member 5, and the periphery of described needle roller 4 contacts with the taper seat of described nose cone 15.
The rearward end of top body 1 is the taper shank portion 11 matched with tailstock tool, and rear end, described taper shank portion 11 forms located block 12.
The front end of top body 1 is top head 17, and described top head 17 is made up of cylindrical section 16 and nose cone 15, and described cylindrical section 16 is connected with the stub end of nose cone 15.
Top body 1 is positioned at described cylindrical section 16 rear end and forms thread segment 18, and the rear end of described thread segment 18 is be molded over the locating stop piece 14 on top body 1.
Cylindrical section 16 is provided with end face bearing 2, an end face of described end face bearing 2 is pressed against on the end face of thread segment 18, the end contact of the stub end of other end and conical sleeve 3, described securing member 5 is screwed onto thread segment 18.
In the present embodiment, securing member 5 is locking nut.
The position being positioned at described locating stop piece 14 rear forms anti-slip part 13 to top body 1, due to top body 1 outer surface smoother in the process of locking nut screwing, therefore can skid, the effect of anti-slip part 13 is to prevent from skidding in rundown process.
More particularly, in the present embodiment, anti-slip part 13 is at the shaping anti-slip tank of the circumferential surface of top body 1.
The embodiment of the centre head of a kind of grinding work-piece inner hole cone of the utility model wall is when work, first will draw together top body 1 is attached on tailstock tool, be mainly on the tailstock of lathe, taper shank portion 11 matches with the tailstock of lathe, and is inserted in the inside taper hole of tapered bore parts by top head 17, and needle roller 4 contacts with taper hole inwall, and the tailstock of mobile lathe is by workpiece pre-tightening, open lathe afterwards, in part High Rotation Speed situation, needle roller 4 pairs of taper hole inwalls carry out grinding makes it bright and clean.
