The invention discloses a kind of thin-wall barrel inner circle tensioning devices, including ring body (1), tensioner skewback (2), adjusting screw (3) and cushion block (4)；Ring body (1) includes an annular surface, and annular surface is that the circumferential direction of notch not sealing surface is provided with along axial direction；There are two in ring body (1) on the inside of notch about the symmetrical tensioner inclined-plane of notch, there is a cushion block holding plane above tensioner inclined-plane and on the inside of notch；There is a screw hole on the upper surface of tensioner skewback (2), both sides of the upper end simultaneously respectively has a skewed surface on tensioner skewback (2), and two skewed surfaces are about screw hole axisymmetrical；Tensioner skewback (2) is connected by adjusting screw (3) with cushion block (4)；Cushion block (4) is placed on cushion block holding plane.The comprehensive engagement of device outer wall and cylinder inboard wall may be implemented in the present invention, and it is convenient, reliable to adjust tensioner degree.
Description
Technical field
It is the present invention relates to inner circle tensioning device, in particular to a kind of compared with capable of being easy adjusting tensioner degree and can be with part inner circle
The thin-wall barrel inner circle tensioning device of comprehensive engagement.
Background technique
Currently used for tensioner inner circle fixture there are mainly two types of.It is supportted one is adjustable by stretching partial dot, part face
The fixture of tight inner circle, such method can only the point of stretching contact or the face of contact, what the point not contacted or face had a deformation can
Energy.Another is manually to knock in oblique wedge to carry out tensioner inner circle, such method the problem is that: such method is also fixture
It is contacted with parts locally, the point not contacted or face have the possibility deformed.The reason of another side is because of vibration knife, when processing one section
Between after, tensioner effect can weaken, and need to remake oblique wedge at this time, increase the investment of human and material resources.
Summary of the invention
The present invention is intended to provide a kind of thin-wall barrel inner circle tensioning device, tensioner face is adjustable, and comprehensive engagement thin wall cylinder
Internal disc.
Specifically, technical scheme is as follows:
A kind of thin-wall barrel inner circle tensioning device, including ring body, tensioner skewback, adjusting screw and cushion block；
The ring body includes an annular surface, and annular surface is that the circumferential direction of notch not sealing surface is provided with along axial direction；
There are two in ring body on the inside of the notch about the symmetrical tensioner inclined-plane of notch, above tensioner inclined-plane and in notch
There is a cushion block holding plane in inside；
There is a screw hole on the upper surface of the tensioner skewback, both sides of the upper end simultaneously respectively has an oblique table on tensioner skewback
Face, and two skewed surfaces are about screw hole axisymmetrical；
The tensioner skewback is connected by adjusting screw with cushion block；
The cushion block is placed on cushion block holding plane.
Measuring flume is circumferentially provided on the ring body exterior surface, and the length direction of measuring flume is parallel to the axis side of ring body
To.
Minimum spacing of the width of rebate less than two tensioner inclined-planes.
The surface of ring body is the plane that a pair is parallel to ring axis at the notch.
Compared with traditional inner circle tensioning device, the invention has the characteristics that:
1, the comprehensive engagement of device outer wall and cylinder inboard wall may be implemented in the present invention；
2, present invention adjustment tensioner degree is convenient, reliable, after processing one end time, if there is loosening, need to only turn connection
Screw rod moves tensioner skewback up, and then stretching part inner wall.

Fig. 1 is tensioning device three-dimensional structure diagram；
Fig. 2~Fig. 4 is ring body structurc three-view diagram；
Fig. 5~Fig. 7 is tensioner skewback structure three-view diagram；
Wherein, 1, ring body；2, tensioner skewback；3, adjusting screw；4, cushion block.
Specific embodiment
Technical solution of the present invention is described further below in conjunction with attached drawing, but required protection scope does not limit to
In described.
As shown in Figure 1, the device is by ring body for the present invention adjustable, comprehensive engagement thin-wall barrel inner circle tensioning device
1, tensioner skewback 2, adjusting screw 3 and cushion block 4 form.Such as Fig. 2~Fig. 4, ring body 1 is used for tensioner part inner headed face, outer surface
As tensioner face；There is the notch opened along axial direction in ring body 1, is two tensioner inclined-planes inside notch, for placing tensioner
Skewback 1,1 end face of ring body at notch are the straight plane that a pair is parallel to 1 axis of ring body, facilitate the free harmomegathus of ring body, tensioner is oblique
There is a square groove above face, places cushion block 4 in slot.Slot at three is circumferentially provided in 1 outer circle of ring body to be convenient for measuring as measuring flume
Size.As shown in Fig. 5~Fig. 7, tensioner skewback 2 is inclined-plane there are two side surface, for cooperating with the tensioner inclined-plane of ring body 1, together
When 2 upper surface of tensioner skewback be provided with threaded hole, adjusting screw 3 can be screwed in.
In use, adjusting as steps described below:
(1) tensioner skewback 2, adjusting screw 3, cushion block 4 are shone and is assembled in ring body 1 shown in Fig. 1.
(2) part is attached in ring body 1, contacts part inner wall with 1 outer circle of ring body.
(3) adjusting screw 3 is turned, moves upwards it with tensioner skewback 2, and then reaches tensioner part inner wall purpose,
If there is gap between part and ring body 1 in processing, repeat step (3).
