Centroid is overlapped with the center of circle of the inner support seat.
Further, anti-slide mark is evenly distributed on the elastic expansion-sleeve outer end face.
Further, the material of the elastic expansion-sleeve is thermoplastic elastic material.
It further, further include an auxiliary installation device, the auxiliary installation device includes the second shaft and anti-skidding
Set, one end of second shaft are plugged into a venthole, and the bar diameter of the other end expands, and is arranged in its surrounding
Anti-slip cover.
The utility model has the advantages that compared with prior art, the invention has the following advantages that the machine of the hollow tube-type part of this kind of inner support
Structure, for special slim cylindrical member, Excircle machining is more complex, has the part of the features such as certain batch, part can be prevented because of stress
And shaking knife leads to entire part deformation, improves machining accuracy, practical value is higher, is suitble to promote the use of.

Specific embodiment
In the following with reference to the drawings and specific embodiments, the present invention is furture elucidated, it should be understood that these embodiments are merely to illustrate
It the present invention rather than limits the scope of the invention, after the present invention has been read, those skilled in the art are to of the invention each
The modification of kind equivalent form falls within the application range as defined in the appended claims.
As shown in Figure 1, Figure 2 and Figure 3, the mechanism of the hollow tube-type part of this inner support, including the first shaft 1, inner support seat 2 and bullet
Property ringfeder 5, there is an inner support seat 2 at the both ends of the first shaft 1 respectively, and the first shaft 1 passes through 2 center of circle of inner support seat and by screw thread company
It connects, 5 inner face of elastic expansion-sleeve is fixedly connected with 2 outer end face of inner support seat, and the outer diameter of elastic expansion-sleeve 5 is adapted to each inner diameter size
Part to be processed, be connected through a screw thread the part that can be applicable in different length；By extremely between inner support seat 2 and the first shaft 1
A few fastener 3 is fixed, is threadedly coupled between fastener 3 and the first shaft 1, can be each in order to device using being threadedly coupled
The dismounting of a part；Inner support seat 2 is collar plate shape support, has at least three ventholes 4 on support, so that the external and internal pressure phase of part
Deng will not be influenced on processing, while the setting of venthole 4 is also convenient for the dismounting on the first shaft of inner support seat 2；It is adjacent
Angulation is identical between venthole 4, and the centroid formed between each venthole 4 is overlapped with the center of circle of inner support seat 2, makes
It is equal to obtain the power from all directions suffered by part 6；It is evenly distributed with anti-slide mark on 5 outer end face of elastic expansion-sleeve, can be increased
Friction between elastic expansion-sleeve 5 and part 6；The material of elastic expansion-sleeve 5 is thermoplastic elastic material, in elastic material damage
Can replace in time, improve the service life of device, and can not only be increased using elastomeric material fastener 3 and part 6 it
Between friction, increase pressure, and elastic expansion-sleeve can also be made to adapt to the internal diameters of different parts using elastomeric material, improve dress
The utilization rate set.
The present embodiment further includes an auxiliary installation device, and the auxiliary installation device includes the second shaft 7 and Anti-slip cover
8, one end of second shaft 7 is plugged into a venthole 4, and the bar diameter of the other end expands, and is arranged in its surrounding
There is Anti-slip cover 8.Second shaft 7 of auxiliary installation device is matched with each venthole 4, can easy disassembly inner support seat 2, it is anti-skidding
The installation of set 8 can reduce power when installation.
In the use of the present invention, the overall length of part 6 and inner hole are worked into drawing size, by the shaft 1 of the internal support device
It is placed in 6 inner hole of part, two inner support seats 2 is successively installed, utilize phase of the auxiliary installation device adjustment inner support seat 2 in part 6
To position, then with the fixed inner support seat 2 of fastener 3, that is, 6 outer circle of part can be processed, while 5 outer diameter of elastic expansion-sleeve of the device can
