Description
Technical field
The utility model relates to welding toolings, especially a kind of to be suitable for welding fixture.
Background technique
There is a kind of " work " shape weldment on present motor oil case, the flange material of upper part and lower part is 5A06,
The cylinder material at middle part is 3A21 aluminium alloy, and weldquality requires level-one；While guaranteeing welding quality, guarantee part again
Requirement for height and top and bottom the depth of parallelism requirement.
And be welding profession problem by 5A06 material and 3A21 aluminium alloy first-order weld quality requirement, conventional soldering method because
Welding deformation greatly and welding defect more than it is difficult to ensure that.Welding quality requirement is now guaranteed using the method for electron-bombardment welding, and it is true
Empty electron beam welding requires zero clearance cooperation between two parts, therefore how to guarantee upper and lower flange and middle part cylinder in welding
The technical issues of position is relatively stable, is a urgent need to resolve.
Summary of the invention
The purpose of this utility model is to design a kind of welding fixture structurally reasonable, using effect is good.
The technical solution of the utility model is a kind of welding fixture, it includes bottom plate, supporting leg, it is characterised in that:
It is equipped with supporting leg in the lower part of bottom plate, the center on bottom plate is equipped with center stand column using center stand column point as the center of circle and is in
Circular distribution has multiple outer columns, and the outside of outer column, which is equipped with, is evenly equipped with pressing plate, and pressing plate is equipped with through-hole, is equipped with spiral shell in through-hole
The bottom of bolt, bolt is corresponding with the screw hole on bottom plate, is equipped with loose pin in the inside of pressing plate, is equipped on the top of column convex
Platform shape limit shaft is equipped with bolt column in the top for having boss shape limit shaft, is equipped with clamp nut, blank holder on bolt column
On be provided with bolt column match through-hole；Interior fagging is equipped in center stand column, the center of interior fagging is provided with through-hole.
Loose pin described further passes through the fixation hole grafting in bottom pegs and bottom plate.
Hand-hold hole is provided on interior fagging described further.
The beneficial effects of the utility model are: can limit the relative altitude position of soldering part and butt welding
The above and below depth of parallelism of pipe fitting is limited, while must guarantee that the zero clearance between each components cooperates, and is welded in part
It can also smoothly be taken out from positioning fixture after the completion；And improve processing quality.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model,
Fig. 2 is the structural schematic diagram of " work " shape weldment described in the utility model.
Specific embodiment
Embodiment is described in detail in conjunction with the figures above,
A kind of welding fixture, it includes bottom plate 1, supporting leg 2, supporting leg is equipped in the lower part of bottom plate, on bottom plate
Center is equipped with center stand column 14, rounded that multiple outer columns 6, outer column is distributed with using center stand column point as the center of circle
Outside be equipped with and be evenly equipped with pressing plate 3, pressing plate is equipped with through-hole, is equipped with bolt 4, the spiral shell on the bottom and bottom plate of bolt in through-hole
Hole is corresponding, is equipped with loose pin 5 in the inside of pressing plate, is equipped with boss shape limit shaft 7, boss shape limit shaft on the top of column
It can be screwed onto the top of column, relative position of such boss shape limit shaft on column is adjustable, can just adjust, convex having
The top of platform shape limit shaft is equipped with bolt column 10, is equipped with clamp nut 9 on bolt column, is provided on blank holder 8 and bolt
The through-hole that column matches, and blank holder is fixed on bolt column using clamp nut；Inner support is equipped in center stand column
Plate 11, the center of interior fagging are provided with through-hole 12；Loose pin described in the present embodiment passes through in bottom pegs and bottom plate
Fixation hole grafting；Hand-hold hole 13 is provided on interior fagging described in the present embodiment.
When the utility model is used, when needing welding workpiece, when first remove the clamp nut filled on bolt column, pressure
Flange is removed, and the bolt that pressing plate has controlled pressing plate is removed, and is first packed into lower flange 14 in lower part, the outer of lower flange is consolidated by pressing plate
Surely it blocks, the inner round portion of activity orientation finger setting lower flange, if flange is off size suitable, it is big various outer diameter can be converted
Small loose pin in the hope of optimal fixed effect, then inner circle cartridge module 15 is centrally disposed, and is installed logical when upper flange 16
The outer that blank holder compresses upper flange is crossed, blank holder is compressed to fix by clamp nut, then interior fagging is installed, in center stand column
On can slide up and down, can prop up between inner cylinder and upper flange, realize workpiece between zero clearance, start to weld.It has welded
Cheng Hou takes out interior fagging, then loosening pressure flange, finally unclamps the pressing plate of lower part, the work being welded can be taken out, be ensure that
The processing quality of tooling.
The above embodiments are merely examples for clarifying the description, and does not limit the embodiments.For institute
For the those of ordinary skill in category field, other various forms of variations or change can also be made on the basis of the above description
It is dynamic.There is no necessity and possibility to exhaust all the enbodiments, and obvious variation extended from this or change
Within the dynamic protection scope created still in the utility model.
