Abstract
A kind of special tooling for reducing apparatus for fixing transformer soldering stress deformation amount, including the framework being welded into by four square tubes, one flat plate is respectively welded with framework front both sides, one piece of gusset is respectively welded with framework reverse side corner, two pieces of reinforcing plates are respectively welded with framework reverse side both sides, and one group of special tooling suit hole corresponding with apparatus for fixing transformer client's mounting hole is offered on framework and its flat board, reinforcing plate.Frock compact of the present utility model, simple to operate, flatness meets client's mounting surface requirement after making apparatus for fixing transformer soldering shaping, reduces folder compared with shape workload, improves product qualification rate and production efficiency.
Description
Technical field
It the utility model is related to technical field of transformer manufacturing, and in particular to one kind reduces transformer soldering stress deformation amount
Special tooling, be mainly used in the final butt welding of the folder from top to bottom of transformer, reduce welding deformation amount, meet that transformer client pacifies
Fill the planarity requirements of end face.
Background technology
The transformer on locomotive is applied, because requirement of mechanical strength is higher, so transformer needs after the completion of final assembling
Folder is welded together mutually, to ensure having enough mechanical strengths, before this, transformer folder from top to bottom soldering after mounting
When, because level weld seam requirement is higher and weld width is larger, folder easily produce soldering deformation, cause transformer client install end face put down
Face degree is poor, and flatness tolerance can only ensure that the vibrations of some transformers and noise test result be not up to standard, client in≤2mm
Mounting hole pitch-row deviation is more than 1mm；So that transformer, because above mentioned problem is done over again, operating efficiency and product qualification rate are low.
The content of the invention
For the deficiencies in the prior art before this, the utility model proposes one kind to reduce apparatus for fixing transformer soldering stress
The special tooling of deflection, the frock compact is simple to operate, and flatness meets client after making apparatus for fixing transformer soldering shaping
Mounting surface requirement, so as to reduce folder compared with shape workload, improve product qualification rate and production efficiency.
The technical solution adopted in the utility model is：A kind of special tool for reducing apparatus for fixing transformer soldering stress deformation amount
Dress, including the framework being welded into by four square tubes, are respectively welded with one flat plate on framework front both sides, respectively add in framework reverse side corner
One piece of gusset is welded, two pieces of reinforcing plates are respectively welded with framework reverse side both sides, and one is offered on framework and its flat board, reinforcing plate
The group special tooling suit hole corresponding with apparatus for fixing transformer client's mounting hole.
In above-mentioned technical proposal, hole for hoist is drilled with the framework corner, welds nut in hole for hoist, nut is connected with suspension ring
It is fixed.
In above-mentioned technical proposal, oblique across the angle arrangement of gusset that the framework corner is respectively welded with, gusset both ends are fixed respectively
In two adjacent square tube of framework.
This frock aims at stationary transformer folder from top to bottom, reduces welding deformation amount of the folder in soldering and design, the work
Dress is simple to manufacture, cost of manufacture is not high, simple to operate, can be just used alone after need to only handing over application method.In transformer production
During, after folder and mounting coil, the folder from top to bottom of transformer needs soldering, because folder soldering has welding stress change
Shape, so as to cause folder flatness overproof.The now mounting surface and peace by special tooling of the present utility model to apparatus for fixing transformer
Dress hole be fixed, reduce welding when deflection, so as to reach it is anticipated that effect, it is convenient, fast, efficient.
The beneficial effects of the utility model：
The utility model is a kind of special tooling for reducing apparatus for fixing transformer soldering stress deformation amount, through using this frock
Afterwards, the folder client mounting surface of the transformer can ensure flatness≤0.5mm, and vibrations and noise test result are fully met
The technical requirements of the product, so as to improve product qualification rate, reduce the operation rework rate of employee.
Brief description of the drawings：
Fig. 1 is that the utility model structure is formally schemed；
Fig. 2 is the utility model structure top view；
Fig. 3 is the utility model structural side view.
Reference：
1-framework, 2-gusset, 3-flat board, 4-reinforcing plate, 5-suspension ring, 6-suit hole.
Embodiment：
Referring to Fig. 1 ~ Fig. 3, the special tooling of the present utility model for reducing apparatus for fixing transformer soldering stress deformation amount, is by 4
Root square tube is welded into 1030*950*80mm framework, and square tube front both sides are respectively welded with 1 piece of 80*1000*5mm flat board, and postwelding enters
Driving is cut milling and put down, and ensures the flatness precision of this plane.4 angles of reverse side are welded with 1 piece of 50*200*10mm gusset, are bored in square tube
1 group of suit hole of Φ 20 is taken, the size of pitch-row is the size of apparatus for fixing transformer client's mounting hole, it is desirable to which precision≤0.5mm, square tube are anti-
Face is welded with 4 pieces of 100*80*5mm reinforcing plate, prevents the hole to be deformed after being repeatedly set with.4 angles of special tooling need to bore 4 Φ
16 holes, interior weldering M16 nut, for twisting M16 suspension ring, to facilitate employee hanged.
By being fixed by bolts to during apparatus for fixing transformer soldering on special tooling of the present utility model, to reduce welding stress
Deformation, to meet the flatness of transformer client's mounting surface.
