The embodiment of the present invention provides a kind of endoporus expanding tense machine, for swelling thin-walled parts 7.Wherein, endoporus
Expanding tense machine includes elastic tensioner ring 1, fixing holder assembly and bolt fastener 4.Elastic tensioner ring 1 has opening
11.Fixing holder assembly includes that first fixes seat 2 and second and fix seat 3, and described first fixes seat 2 and
Two fix seat 3 symmetry is fixed on the two ends of described opening 11, and described first fixes and offer first on seat 2
Screwed hole 21, described second fixes and offers the second screwed hole 31 on seat 3, described first screwed hole 21 He
Described second screwed hole 31 is oppositely arranged and thread rotary orientation is contrary.Bolt fastener 4 two ends are provided with screw thread
Oppositely oriented external screw thread.Wherein, the two ends of described bolt fastener 4 respectively with described first screwed hole
21 and second screwed hole 31 threaded.
The material of elastic tensioner ring can select spring steel, and spring steel has certain elasticity and rigidity.Elastic
The thickness of tensioner ring depends on the thin and thick treating the thin-walled parts of swelling.The Main Function of fixing holder assembly is for spiral shell
Bolt securing member provides and supports.As a example by the direction shown in Fig. 1, if first fixes the first screwed hole on seat
Rotation direction to the left, then second fixes the rotation direction of the second screwed hole on seat to the right.Bolt fastener and the first spiral shell
To the left, the threaded one end rotation direction coordinated with the second screwed hole is to the right for the threaded one end rotation direction that pit coordinates.That
, rotating bolt securing member in one direction, the opening on elastic tensioner ring can increase, and elastic tensioner ring is close to
On the inwall of thin-walled parts, and expand outwardly, to realize swelling thin-walled parts.Above-mentioned swelling process phase
When in adding the thickness of thin-walled parts, thus enhance the rigidity of thin-walled parts.Turn in the opposite direction
Dynamic bolt fastener, the opening on elastic tensioner ring can reduce, with by endoporus expanding tense machine in thin-walled parts
Take off on hole.
Visible, that technique scheme provides endoporus expanding tense machine, it is possible to realize swelling thin-walled parts, to increase
The intensity of strong thin-walled parts so that thin-walled parts is in clamping and adds and occurs without deformation man-hour.
It is described below first to fix seat 2 and second and fix the preferred implementation of seat 3.
First fixes seat 2 includes that the first clamp 22 and first connects bearing pin 23.First clamp 22 quantity is
Two, two described first clamps 22 are fixed on one end of described opening 11, each described first clamp 22
On offer the first connecting hole 24.First connects the mid diameter of bearing pin 23 more than described first connecting hole
The diameter of 24, the described first two ends connecting bearing pin 23 are separately positioned on each to described first connecting hole 24
In；Described first middle part connecting bearing pin 23 offers described first screwed hole 21.
Described second fixes seat 3 includes that the second clamp 32 and second connects bearing pin 33.Second clamp 32 number
Amount is two, and two described second clamps 32 are fixed on the other end of described opening 11, each described second
The second connecting hole 34 is offered on clamp 32.Second connects the mid diameter of bearing pin 33 more than described second
The diameter of connecting hole 34, the described second two ends connecting bearing pin 33 are separately positioned on each to described second company
Connect in hole 34；Described second middle part connecting bearing pin 33 offers described second screwed hole 31.
Above-mentioned first fix seat 2 fix with second seat 3 structure be almost the most the same, except the first screw thread
The rotation direction of hole 21 and the second screwed hole 31 is different.This sentences first and fixes detailed description as a example by seat 2,
Second fixes seat 3 can refer to, repeat no more herein.Two the first clamps 22 are respectively welded at elastic tensioner ring
On two sides of 1, the first clamp 22 can be flat board or arc.Herein, first connects bearing pin 23
Overall stepped, the diameter at two ends is little, and middle diameter is big.First two ends connecting bearing pin 23 can
In the first connecting hole 24 freely rotatable.During installation, first one of them first clamp 22 is installed and puts in place,
Then first connection bearing pin 23 is installed, another first clamp 22 is installed put in place, finally the most again
Two the first clamps 22 are welded with elastic tensioner ring 1.
For the ease of rotating bolt securing member 4, further, the middle part of described bolt fastener 4 is offered
There is the handle hole 41 of several radial direction.When needing rotating bolt securing member 4, spanner or reinforcing bar are inserted into
In handle hole 41, then pull spanner or reinforcing bar.
In actual application, need thin-walled parts 7 of slinging, thin-walled parts 7 does not has to connect except endoporus
Connect the place of lifting device, therefore preferably, the inwall of described elastic tensioner ring 1 is symmetrically arranged with several to convex
Play 5, on each described protruding 5, offer through hole.
Through hole can be connected with lifting device, with thin-walled parts of slinging.
It is understood that during using above-mentioned endoporus expanding tense machine, thin-walled parts 7 should do not destroyed,
The degrees of expansion of elastic tensioner ring 1 should be within the scope of certain, therefore preferably, and the width of described opening 11
For 1mm-5mm.
The manufacturing process of endoporus expanding tense machine is described below:
First get out each component part.Connect bearing pin 23 by first and the second connection bearing pin 33 correspondence is screwed in
The two ends of bolt fastener 4, first connects bearing pin 23 and second connects bearing pin 33 relative to bolt fastening
Part 4 wants almost symmetry.
Then install first and fix seat 2: connect bearing pin 23 first clamp 22 installed therein by first
The first connecting hole 24 in, then another block first clamp 22 peace is attached on elastic tensioner ring 1, adjusts
Position also compresses.
In like manner install second and fix seat 3.
Rotating bolt securing member 4, it is ensured that rotate flexibly, afterwards by the first clamp 22 and the second clamp 32
Welding together with elastic tensioner ring 1, so far endoporus expanding tense machine makes complete.
In practice, can be according to the different endoporus expanding tense machines making different size of thin-walled parts size.
During use, endoporus expanding tense machine is placed on product (such as thin-walled parts, as shown in Figure 2) corresponding aperture
In, regulate bolt fastener 4, make the elastic tensioner ring 1 of endoporus expanding tense machine stretch, to reach swelling or to release
The purpose put.
During as lifted, it is possible to use the projection 5 of welding in elastic tensioner ring 1, on protruding 5, process through hole
51(is specially screwed hole herein) in order to be screwed into lifting screw, as shown in Figure 2.
The endoporus expanding tense machine that technique scheme provides, it is possible to realize the swelling to thin-walled parts so that thin
Wall part will not deform because of clamping or processing；It addition, be provided with on endoporus expanding tense machine for lifting work
The through hole that tool is connected so that thin-walled parts is easy to be lifted.
Last it is noted that various embodiments above is only in order to illustrate technical scheme, rather than right
It limits；Although the present invention being described in detail with reference to foregoing embodiments, this area common
Skilled artisans appreciate that the technical scheme described in foregoing embodiments still can be modified by it,
Or the most some or all of technical characteristic is carried out equivalent；And these amendments or replacement, and
The essence not making appropriate technical solution departs from the scope of various embodiments of the present invention technical scheme.
