Directly.
Currently, since the heavy caliber length of tube that pumps up water is relatively long, when being processed using large-scale vertical lathe, processing charges
It is with high costs with height；And horizontal lathe is used to process lifting pipe, although both economical, concentricity and verticality are difficult to ensure.
Utility model content
The purpose of this utility model is in view of the above problems, providing a kind of heavy caliber lifting pipe Vehicle Processing mandrel, its energy
Solve the problem of that its concentricity and verticality are difficult to ensure when using horizontal lathe processing lifting pipe.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of heavy caliber lifting pipe Vehicle Processing core
Axis, it includes mandrel, and the mandrel right end is provided with and matches centre bore used for positioning with lathe centre, the mandrel left end
It is provided with and matches detent flange used for positioning with lathe chuck；First is coaxially arranged with close to left end on the mandrel to hold out against
Component, described first hold out against component include annular array be arranged on mandrel stud, the nut for locking the stud and
For positioning the nut of lifting pipe to be processed；Second, which is coaxially arranged with, close to right end on the mandrel holds out against component, described second
Holding out against component includes sleeve, the stud that annular array is arranged on sleeve, the nut for locking the stud and for positioning
The nut of lifting pipe to be processed, the sleeve are arranged by stud onto mandrel.
Further, it described first holds out against component and second and holds out against the equal annular array of component and be provided with 4 studs.
Further, the centre bore is through-hole.
Further, the centre bore right end is provided with oblique angle.
Further, the chuck is three-jaw self-centering chuck or four-jaw chuck.
The utility model has the advantages that the utility model provides a kind of heavy caliber lifting pipe Vehicle Processing mandrel, it uses horizontal lathe
Lifting pipe is processed, processing charges is low, and can guarantee the concentricity and verticality of lifting pipe, on the basis of guaranteeing quality, significantly
Reduce processing cost.

Specific embodiment
In order to enable those skilled in the art to better understand the technical solutions of the present invention, with reference to the accompanying drawing to this reality
Be described in detail with novel, the description of this part be only it is exemplary and explanatory, should not be to the protection scope of the utility model
There is any restriction effect.
As shown in Figure 1-Figure 3, the specific structure of the utility model are as follows: a kind of heavy caliber lifting pipe Vehicle Processing mandrel, it
Including mandrel 1,1 right end of mandrel is provided with and matches centre bore 102 used for positioning with lathe centre 4, and the mandrel 1 is left
End, which is provided with, matches detent flange 101 used for positioning with lathe chuck；The is coaxially arranged with close to left end on the mandrel 1
One holds out against component 2, described first hold out against component 2 include annular array be arranged on mandrel 1 stud 21, for locking the spiral shell
The nut 23 of column 21 and nut 22 for positioning lifting pipe 3 to be processed；Second is coaxially arranged with close to right end on the mandrel 1
Hold out against component 5, described second hold out against component 5 include sleeve 51, annular array be arranged on sleeve 51 stud 21, for locking
The nut 23 of the stud 21 and nut 22 for positioning lifting pipe 3 to be processed, the sleeve 51 are arrived by the setting of stud 21
On mandrel 1.
In order to preferably lock lifting pipe 3, described first, which holds out against component 2 and second, holds out against the setting of the equal annular array of component 5
There are 4 studs 21.
As shown in Figure 1, the centre bore 102 is through-hole.
In order to be more convenient positioning core axle 1,102 right end of centre bore is provided with oblique angle.
In order to position more accurate stable, the chuck is three-jaw self-centering chuck or four-jaw chuck.
Mandrel 1: being first mounted in lifting pipe 3 to be processed by specifically used principle, and use first holds out against component 2, second holds out against
Component 5 corrects and holds out against lifting pipe 3；Then 101 outer circle of detent flange that 1 left end of mandrel is clamped with the chuck of lathe, uses lathe
