Abstract

The utility model relates to an auxiliary fixture for clamping a special curved surface. When a machine tool fixture clamp a workpiece with the aid of the auxiliary fixture, the clamping accuracy can be improved, the product percent of pass is increased, the production cost is lowered and the production period is reduced. The auxiliary fixture comprises a fixture body in the shape of a hollow cylinder body, wherein deformed grooves are uniformly distributed on the sidewall of the fixture body and extend from one end to the other end.

Description

A kind of auxiliary clamp
Technical field
The utility model relates to a kind of auxiliary clamp that is used for clamp axis to non-round surface.
Background technology
At present, using universal fixturing in the machining, generally all is to design at the workpiece that axially is round surface, when clamp axis during to the workpiece of non-round surface, taper seat for example is often because contact area is little, contact surface stress is excessive, causes contact surface to produce plastic deformation.Reduce the clamping precision thus, increased percent defective, improved production cost, increased the production cycle.
The utility model content
The purpose of this utility model is: the problem at universal fixturing exists when the workpiece of the non-round surface of clamping provides a kind of auxiliary clamp that is exclusively used in the workpiece of the non-round surface of clamping.
The purpose of this utility model is achieved in that a kind of auxiliary clamp, comprises a chuck body, it is characterized in that: chuck body is hollow cylindrical shell, and the sidewall of chuck body is provided with equally distributed distortion groove, and described distortion groove is extended to the other end by an end face.
As improvement of the present utility model: the distortion groove terminates in and arrives at before the other end.Distortion groove clearing end is provided with the stress groove.
As improvement of the present utility model, the quantity of described distortion groove is even number, and wherein half is a starting point with chuck body one end, and second half is a starting point with the chuck body other end; The equidistant alternate setting of the distortion groove that starting point is different.
In distortion groove of the present utility model, can there be a distortion groove to extend to the other end and forms and run through groove by chuck body one end.
As improvement of the present utility model, the inner surface of chuck body is provided with protective layer.
As improvement of the present utility model, a boss around chuck body is set on the outer surface of chuck body.
Advantage of the present utility model is: because chuck body is hollow cylindrical shell, its sidewall is provided with equally distributed distortion groove, in use, the inwall of chuck body can change with the surface curve of the workpiece of non-round surface, make anchor clamps closely be applied to the surface of workpiece, reduce or avoid the infringement of anchor clamps, improve the clamping precision, increase product percent of pass the surface of workpiece; Boss on the chuck body outer surface can and make in the spacing processing stations of anchor clamps easily.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model embodiment.
Among the figure: 1, chuck body, 2, the distortion groove, 3, boss.
The specific embodiment
As shown in Figure 1, the auxiliary clamp in the present embodiment comprises a chuck body 1, and chuck body 1 has the inner surface 1-1 that cooperatively interacts with the outer surface that is held workpiece, and the outer surface 1-2 that cooperatively interacts with the inner surface of jig.The sidewall of chuck body 1 is provided with equally distributed distortion groove 2, and described distortion groove 2 is extended to the other end by an end face.
In the present embodiment, four distortion grooves 2 are set evenly on the sidewall of chuck body 1, wherein two is starting point with chuck body one end, and two is starting point with the chuck body other end; The equidistant alternate setting of the distortion groove that starting point is different, each is out of shape groove 2 clearing ends and is provided with stress groove 2-1; Simultaneously, a boss 3 around chuck body 1 is set on the outer surface of described chuck body 1.
During concrete enforcement, one of them distortion groove 2 can be extended to the other end by an end of chuck body 1 and form and run through groove.
During concrete enforcement, can also on the inner surface of described chuck body 1, protective layer be set.Described protective layer can be nonmetallic substances such as plastics, rubber.
