Setting forms a contact chamber, it is intracavitary simultaneously that workpiece bottom is installed on the contact there are two rolling bearing between two rolling bearings
It is in rolling contact with two rolling bearings, the middle and centre head for contacting chamber are located on same axis.
The auxiliary support assemblies include the first connecting bushing, bending bar, connecting rod, the as a preferred technical solution,
Two connecting bushings, interconnecting piece and a support frame, two rolling bearings are installed in support frame, and the first connecting bushing is fixedly mounted
In the outside of adjusting nut, bending bar is installed on the first connecting bushing, and an elasticity is arranged between the bending bar and connecting rod
Part, the second connecting bushing are fixedly installed in connecting rod, and support frame as described above is installed on the second connecting bushing by interconnecting piece.
The elastic component is a connecting spring as a preferred technical solution, and connecting spring one end is connect with bending bar, separately
One end is fixedly connected with the connecting rod.
The centre of support frame as described above has about one perforative installation cavity, rolling bearing as a preferred technical solution,
Centre passes through a piece connecting shaft of setting, and rolling bearing is fixedly installed in installation cavity by connecting shaft, the upper and lower side of rolling bearing
The upper and lower side of support frame is stretched out in respectively.
The beneficial effects of the utility model are: the auxiliary of the utility model is top, it can be achieved that secondary positioning branch to workpiece
Support guarantees the steady processing of long axis workpiece, and centre head can realize automatic rotation relative to main part, reduce rubbing between workpiece
It wipes, increases service life.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only

Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the structural schematic diagram of the support frame of the utility model；
Fig. 3 is the usage state diagram of the utility model.
Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, abstract and attached drawing), except non-specifically chatting
It states, can be replaced by other alternative features that are equivalent or have similar purpose.That is, unless specifically stated, each feature is only
It is an example in a series of equivalent or similar characteristics.
As shown in Figure 1, including main part 11, thread segment 15, adjusting nut 9, centre head 12 and an auxiliary support assemblies,
Thread segment 15 is installed on a side end face of main part 11, and adjusting nut 9 is installed on thread segment 15, the head end of thread segment 15
One bearing 13 of insertion setting, one end of centre head 12 are fixedly installed in the bearing hole of bearing 13 on face, and auxiliary support assemblies are solid
Dingan County is loaded on the outside of adjusting nut 9, rolling bearing 1 there are two settings on auxiliary support assemblies, shape between two rolling bearings 1
At a contact chamber, it is intracavitary and be in rolling contact with two rolling bearings 1 that 17 bottom of workpiece is installed on the contact, contacts the centre of chamber
Place is located on same axis with centre head 12.
Wherein, auxiliary support assemblies include the first connecting bushing 14, bending bar 8, connecting rod 6, the second connecting bushing 5, connect
Socket part 4 and a support frame 2, two rolling bearings 1 are installed in support frame 2, and the first connecting bushing 4 is fixedly installed in adjusting spiral shell
The outside of mother 9, bending bar 8 are installed on the first connecting bushing 14, and an elastic component 7 is arranged between bending bar 8 and connecting rod 6, the
