Description
Technical field
The utility model is related to a kind of hollow thickness of pipe wall holding consistency mandrels, belong to hollow pipe processing technique field.
Background technology
It when existing thin-wall long and thin hollow pipe is processed, needs to position using mandrel, makes adding for hollow shaft outer round surface
Work benchmark is consistent with machined endoporus, to ensure that the hollow thickness of pipe wall processed is consistent, existing mandrel fixture
With following defect：
1, thin-wall long and thin hollow pipe clamping is cumbersome, efficiency is low；
2, hollow the being consistent property of thickness of pipe wall processed is bad.
Utility model content
The utility model aim is to provide a kind of hollow thickness of pipe wall holding consistency mandrel, simple in structure, processing effect
It is good, improve processing efficiency.
Hollow thickness of pipe wall holding consistency mandrel described in the utility model, including mandrel, mandrel both ends are set there are two ruler
Very little identical multi-diameter shaft, ladder shaft diameter are less than axle diameter, and each multi-diameter shaft is cased with slidable ring slider, and ring slider is set
There are annular convex platform, the outer diameter of annular convex platform to be more than the outer diameter of ring slider, each mandrel is equipped with the fastening spiral shell being threadedly coupled with it
Mother, fastening nut are located at the outside of each annular convex platform.
Multi-diameter shaft both ends of the surface are equipped with centre bore.
Fastening nut outer surface is equipped with fastening blind hole, and insertion spanner is contributed to turn fixation to fastening nut.
Ring slider outer diameter is equal with the internal diameter of hollow pipe to be processed.
The utility model compared with prior art, has the advantages that.
1, the utility model can realize the quick-clamping of thin-wall long and thin hollow pipe, lower the labor intensity of worker, improve life
Produce efficiency；
2, the utility model ensures that the machining benchmark of hollow pipe outer circle table is consistent with machined endoporus, to ensure processing
Hollow thickness of pipe wall is consistent afterwards；
3, the utility model round slider can be adjusted between screw thread and step, meet the hollow pipe processing need of different length
It asks.

Specific implementation mode
With reference to embodiment and Figure of description, the utility model is described in further detail.
As shown in Figs 1-4, hollow thickness of pipe wall holding consistency mandrel described in the utility model, including mandrel 3, mandrel 3
Both ends are set there are two the identical multi-diameter shaft 4 of size, and 4 diameter of multi-diameter shaft is less than 3 diameter of mandrel, and each multi-diameter shaft 4 is cased with slidably
Ring slider 2, ring slider 2 are equipped with annular convex platform 2-1, and the outer diameter of annular convex platform 2-1 is more than the outer diameter of ring slider 2, each
Mandrel 3 is equipped with the fastening nut 1 being threadedly coupled with it, and fastening nut 1 is located at the outside of each annular convex platform 2-1.
4 both ends of the surface of multi-diameter shaft are equipped with centre bore 4-1.
1 outer surface of fastening nut is equipped with fastening blind hole 1-1.
2 outer diameter of ring slider is equal with the internal diameter of hollow pipe to be processed.
When the utility model is used, 2 outer round surface of the ring slider bore area machined with hollow pipe contacts, and ensures empty
Heart pipe outer round surface machining benchmark is contacted with machined endoporus；Fastening nut 1 is tightened, the sides annular convex platform 2-1 of ring slider 2 are made
The side in face and hollow pipe both ends to be processed pushes against, to make hollow pipe be rotated together with mandrel 3；Utilize 4 both ends of the surface of multi-diameter shaft
Centre bore 4-1 by two top clampings to lathe, to carry out the processing of hollow pipe outer round surface.
