Description
Technical Field
The utility model belongs to the technical field of gear machining makes, concretely relates to manual tight device that expands of gear hobbing.
Background
Traditional gear hobbing frock preparation is simpler, but the product precision that processes out is lower, unstable, and is stricter to the dimensional requirement of hole, is difficult to control. The large clearance makes subsequent gear grinding difficult, and subsequent machining has to be ensured by increasing the margin, which not only increases the cost, but also has some influence on the strength of the gear. The small clearance is difficult to clamp, and some ordered hydraulic expansion mechanisms are expensive, long in order period, have certain specific requirements on a machine tool, and are higher in cost for small-batch products. Therefore, it is required to develop a hobbing manual tightening device.
Disclosure of Invention
For solving the problem that exists among the prior art, the utility model provides a manual tight device that expands of gear hobbing, including body, base and positioning disk, the base with the positioning disk sets up the outside of body, one side of body with connect through interior hexagonal cylinder head screw I between the base, the opposite side of body with connect through interior hexagonal cylinder head screw III between the positioning disk.
Preferably, a cylindrical pin I is arranged on one side surface of the body.
In any of the above aspects, preferably, a cylindrical helical compression spring is provided between the body and the positioning plate.
In any of the above solutions, preferably, a flange is disposed at one end of the base.
In any of the above schemes, preferably, one end of the base is connected with the flange through an inner hexagonal socket head cap screw ii.
In any of the above schemes, preferably, a cylindrical pin ii is arranged between the positioning disc and the body.
The manual gear hobbing expansion device of the utility model has simple structure, economy and practicality and easy operation; the precision of the product is greatly improved and is stable; the working efficiency is greatly improved; the inner hole of the product is not easy to be pulled.
