Abstract

The utility model discloses a gear shaving expansion sleeve which comprises a support shaft, wherein a plane is arranged on the side wall of the lower part of the support shaft; the upper end of the support shaft is sequentially connected with a stop platform and a cone shaft; the upper end of the cone shaft is a cylinder with a thread; the cone shaft is matched with an expansion shaft; the expansion sleeve is a ring with an axial taper hole; axial slits are arranged on the expansion sleeve; the slits extend from one end surface to the other end surface respectively and are sequentially distributed at intervals; and a dead bolt is screwed on the cylinder with a thread. The gear shaving expansion sleeve disclosed by the utility model has a simple and skillful structure, can conveniently and quickly clamp a gear to be processed, and is not easily loosened and can clamp the gear tightly; and a fixture and a workpiece are not easily damaged due to elastic arrangement.

Description

The gear shaving expansion set
Technical field:
The utility model relates to the Gear Processing field of tool, and concrete is a kind of gear shaving expansion set.
Background technology:
In field of machining, a lot of workpiece need special-purpose anchor clamps when carrying out frock, could effectively carry out frock, thereby in the processing of descending the step; If adopt general universal fixturing, as the Gear Processing that the utility model relates to, processing is changed than very fast; Convenient mounting and clamping is difficult for getting loose, and if when adopting the work of traditional anchor clamps; The speed of changing is slow, and efficient is low, and not easy to operate.
Former Fixture for Gear-shaving, its positioning core axle, cooperating with the workpiece endoporus is matched in clearance, this gap increases the tooth pitch accumulation that directly causes gear in shaving.Be the further Gear Processing precision that improves, the ringfeder anchor clamps that adopt the utility model to relate to, workpiece centering is accurate, and machining accuracy can improve 1 accuracy class, and the while can be eliminated interior hole size variation, to the influence of shaving precision.
The utility model content:
The utility model provides a kind of conveniently gear shaving expansion set for solving deficiency of the prior art.
The technical scheme of the utility model:
The gear shaving expansion set comprises bolster, it is characterized in that: have a plane on the described bolster lower sides; The upper end connects resistance platform, the axis of cone successively, and axis of cone upper end is screwed cylinder, and the described axis of cone is combined with expansion set; Described expansion set is the annulus that has axial taper hole; Have axial cracking on the expansion set, described crack respectively extended and is intervally arranged successively to the other end by one of them end face, screwed togather gim peg on the described screwed cylinder.
The advantage of the utility model:
The utility model is simple in structure and ingenious, and conveniently the clamping gear is processed, and is difficult for getting loose; Clamping tighter, flexible setting, anchor clamps and workpiece are not fragile; The location is accurate, and can eliminate hole size variation in the workpiece, to the influence of machining accuracy.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
The gear shaving expansion set comprises bolster 1, has a plane 2 on described bolster 1 lower sides; The upper end connects resistance platform 3, the axis of cone 4 successively, and the axis of cone 4 upper ends are screwed cylinder 5, and the described axis of cone 4 is combined with expansion set 6; Described expansion set 6 is for having the annulus of axial taper hole; Have on the expansion set 6 and axial crack 7, described cracking 7 extended and is intervally arranged successively to the other end by one of them end face respectively, screwed togather gim peg 8 on the described screwed cylinder 5.
