Description
Technical field
The utility model relates to a kind of cylinder-shaped thin-wall part Split type flexible internal support devices, belong to field of machining.
Background technique
Certain product be both ends open cylinder-shaped thin-wall part, because its both ends of the surface deformed after Tempering and Quenching it is larger, cannot
Meet welding requirements, in order to reduce the deformation of heat treatment, therefore both ends is designed as the thin-wall construction that there is step in inner cavity, such as Fig. 1
It is shown, it is convenient for heat treating trimming.It needs to process welding cut after heat treatment, that is, removes both ends step, be processed as the wall thickness such as approximation.
The workpiece has ovalizing deflection after Tempering and Quenching, adds to the machine of welding cut and is affected, traditional internal support device is applicable in
In shape in part is consistent or the lesser situation of difference, and inconvenient oral area step processing, the workpiece diameter step difference is larger, adopts
With traditional internal support device, not only stroke is inadequate, is not easy to process, it would be highly desirable to new internal support device be needed to occur.
Utility model content
Purpose of the utility model is to solve to interior step cylinder-shaped thin-wall part carry out inner support when, difficulty compared with
Greatly, the problem of influencing the processing of workpiece postorder, and a kind of cylinder-shaped thin-wall part Split type flexible internal support device is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of cylinder-shaped thin-wall part Split type flexible internal support device of the utility model, including cone centre, resilient disc,
Elastic clamp；
The elasticity clamp is the thin-wall tube-shaped element of both ends open, and the outer diameter of elastic clamp is less than in inner support workpiece
Diameter is provided with the expansion slot of one group of circumference uniform distribution on elastic clamp side wall；Every expansion slot be from one end end of elastic clamp to
The other end is axially extending, and the fluting of adjacent two expansion slots is contrary；The both ends inner wall of elastic clamp is processed oriented respectively
The conical surface of outer expandable；
The resilient disc is that circular ring shape component radially waits bulk-breaking structure made of point cutting, is provided on each resilient disc bulk-breaking
The fluting of the expansion slot radially extended, adjacent two expansion slots is contrary；The inner wall outer end of resilient disc component is machined with annular
Limiting stand；
The front end of cone centre is machined with and shape matches in the both ends inner wall of elastic clamp the conical surface；
Elastic clamp is packed into the inner cavity of workpiece, and each bulk-breaking of two resilient discs is mounted on the both ends of elastic clamp, and leads to
The annular stop platform for crossing two resilient disc component inner cavities limits two resilient disc component relative resilient clamps axially inwards；Two
A cone centre is inserted into from the inward at both ends of elastic clamp respectively, makes elastic clamp and two outside uniform expansions of resilient disc.
Beneficial effect
The internal support device of the utility model, the processing for preferably resolving thin-wall workpiece both ends inner mold when having step surface, subtracts
Small influence of the workpiece ovalizing deflection to machining, preferably meets processing request, solving traditional internal support device cannot
The difficulty of shape in end face is enough processed, the interchangeability of device is preferable, and can be realized Seriation Design, to add to the type workpiece
Work has accumulated experience.

Embodiment
A kind of cylinder-shaped thin-wall part Split type flexible internal support device of the utility model, as shown in Fig. 2, including taper top
Point 1, resilient disc 2, elastic clamp 3；
As shown in figure 3, the elasticity clamp 3 is the thin-wall tube-shaped element of both ends open, the outer diameter of elastic clamp 3 is less than to interior
The internal diameter of workpiece is supportted, the expansion slot of one group of circumference uniform distribution is provided on elastic 3 side wall of clamp；Every expansion slot is from elastic clamp
One end end is axially extending to the other end, and the fluting of adjacent two expansion slots is contrary；The both ends inner wall of elastic clamp 3 point
It is not machined with the conical surface extended outward；
As shown in figure 4, the resilient disc 2 is that circular ring shape component radially waits bulk-breaking structure made of point cutting, each elasticity
The expansion slot radially extended is provided on 2 bulk-breaking of disk, the fluting of adjacent two expansion slots is contrary；The inner wall of 2 component of resilient disc
Outer end is machined with annular stop platform；
The front end of cone centre 1 is machined with and shape matches in the both ends inner wall of elastic clamp 3 the conical surface.
When to workpiece inner support, elastic clamp 3 is first packed into the inner cavity of workpiece, then each bulk-breaking of two resilient discs 2 is pacified
Mounted in the both ends of elastic clamp 3, and pass through the annular stop platform of two 2 component inner cavities of resilient disc, makes two resilient discs, 2 component phase
Elastic clamp 3 is limited axially inwards；Two cone centres 1 are inserted into from the inward at both ends of elastic clamp 3 respectively, in insertion process
In, two cone centres 1 make elastic clamp 3 and two outside uniform expansions of resilient disc 2 by the conical surface of front end, guarantee workpiece
Both ends are held round；, it can be achieved that processing to workpiece both ends inner wall step under the state that holds round.
