Description
Technical field
This utility model is related to practical application in iron pipe with flange welding for the support mechanism in a kind of self-centering, specially
A kind of three-jaw centering internal stay fixture.
Background technology
Flange and pipeline butt girth welding seam are common weld seam forms in production, affect its postwelding product size precision and shape
The factor of position tolerance mainly has state before the weldering of workpiece, the tight situation of work piece positioning and welding procedure.This tripartite's face ring because
In element, before workpiece weldering, with machine plus best, section bar takes second place state, and panel beating is worst, is limited to design requirement and special process route, workpiece
Before weldering, state is often to determine；To concrete material, welding procedure also has corresponding scope；Although have control heat input,
The technological measures such as trailing peening, Follow-up rapid cooling, appropriate design welding sequence, but the control to welding deformation, largely still
Positioning clamping depending on workpiece.Therefore impact group welding piece postwelding dimensional accuracy and the most important controllable factor of form and position tolerance are exactly
The clamping state of workpiece.Practical experience also demonstrates this point: to stable welding conditions, clamping is to determine whether product occurs
Overproof key.Therefore, a kind of frock of low cost of design completes the higher girth welding of required precision with existing equipment cooperation
Necessitate.In the girth welding with flange for the pipeline, interior pushing out ring is a kind of conventional, technique of energy effective control welding deformation
Equipment.But the interior pushing out ring of common girth welding is all it is difficult to realize high-precision welding without heart axle.
Content of the invention
For many problem on deformation of above-mentioned appearance, this utility model provides a kind of centering that can automatically compensate difference in internal diameters
Internal stay fixture.
A kind of three-jaw centering internal stay fixture, including flange fixed claw, is placed in the input of described flange fixed claw center in the hole
Axle, is characterized in that described flange fixed claw medial center hole site is provided with concentric fixed cover, uniform on the periphery of fixed cover
There are three journal stirrups, wear described fixed cover in described input shaft, be formed with screw thread in input shaft front portion, on described screw thread, coupling has activity
Set, is evenly equipped with three movable sleeve journal stirrups on the periphery of movable sleeve, is provided with slide block, the two ends of described slide block are fixed respectively
There is slide block journal stirrup, the slide block journal stirrup at described two ends is connected with movable sleeve journal stirrup with journal stirrup respectively by connecting rod.
A kind of described three-jaw centering internal stay fixture, is characterized in that described movable sleeve is dextrorotation movable sleeve.
A kind of three-jaw centering internal stay fixture of the present utility model, by dextrorotation movable sleeve on input shaft and movable sleeve journal stirrup with
Fixed cover and journal stirrup thereon and slide block, slide block journal stirrup and connecting rod constitute a linkage being placed in pipe fitting, play automatically
Feel relieved, align, coordinate the special welding equipment voluntarily developed simultaneously, for the girth welding of pipeline and flange, real with low cost
Existing high-precision welding.Its structure is simple, easy to use it is adaptable to multiple different pipelines and the welding of flange, greatly carry
High production efficiency.

Specific embodiment
Below in conjunction with the accompanying drawings and be embodied as case this utility model is described further.
Referring to the drawings shown in 1-3, the pin-and-hole that three-jaw flange fixed claw 2 is circumferentially provided with array is used for mounting flange
11, constitute an interior pushing out ring being used for tensioner flange.Wear flange fixed claw mesopore in input shaft 1, become heart axle；Fixed cover 3 with
Flange fixed claw 2 spot welding is fixed；Fixed cover is worn, three or more journal stirrups 4 are uniformly fixed to described solid in input shaft (heart axle)
Surely on the excircle of set 3, the periphery of heart axle is formed with screw thread, dextrorotation movable sleeve 5 is mated in the input shaft (heart by female thread
Axle) on, the outer circumference surface of movable sleeve 5 is fixed with movable sleeve journal stirrup 10 corresponding with journal stirrup 4, is provided with slide block 8, in slide block 8
Be respectively fixed at two ends with slide block journal stirrup 7, the slide block journal stirrup 7 at this two ends pass through connecting rod 6 respectively with fixed cover on journal stirrup 4 and activity
Movable sleeve journal stirrup 10 on set 5 connects, and the quantity of described slide block 8 is identical with the quantity of journal stirrup or movable sleeve journal stirrup.Above-mentioned input
Axle (heart axle) 1, fixed cover 3, movable sleeve 5 connecting rod 6 and slide block 8 form a set of linkage in order to drive interior pushing out ring；During work, should
Interior pushing out ring is placed in pipe fitting 12, sealed by connecting pin 9 between connecting rod and each journal stirrup.
This mechanism has good self-centering function, automatically can compensate difference in internal diameters, and can fit in the range of certain diameter
Answer the fixed clamp of different-diameter workpiece, complete the annular solder of workpiece weld seam simultaneously.Automatically pipeline and the method for difference in internal diameters are compensated
Blue Clamp for welding,
During work, with the rotation of input shaft 1, because flange fixed claw limits the displacement of input shaft, therefore input shaft
Only rotate without moving movement, fixed cover and dextrorotation slip cap do relative motion, and carry movable slider 8 synchronous by connecting rod 6
Outwards strut, complete interior pushing out ring spreading action.Screw thread slide block put in place and tensioner pipeline after self-locking, after spot welding terminate after pine
Open.Assembly precision adopts dial gauge to measure.
Due to 2 interior pushing out rings being had on a heart axle, the flange of tensioner butt welding and pipeline respectively, and pushing out ring center roller in two
It is to be ensured by the machining accuracy of fixture with one heart, thus pipeline and flange center roller can be realized during interior pushing out ring spreading
Self-centering, makes pipeline and flange joint realize firm combination.It is many that this structure makes the workload before weldering mitigate, and improves
The service life of fixture, reduces cost indirectly.Can compensate for the difference in internal diameters of pipeline and flange, eliminate the pipeline thereby resulting in
Flange decentraction.
In addition, screw pair adopts root of the tooth intensity high, processing technology is good, and internal and external threads centering is good, has self-lock ability
Trapezoidal thread.Mainly consider in manufacture that the motion of each moving component is synchronous and strut the circularity precision after putting in place with slide block, so
It should be noted that the concordance of processing, its circular arc answers overall processing to slide block.
