Abstract
The utility model discloses a kind of anti-deformation device for fuel tank welding, belong to armored vehicle technical field, the device ensure that welding quality of its fuel tank in miscellaneous part welding process, the stairstepping cylinder that the device is made up of the first cylinder, the second cylinder and the 3rd cylinder；Stairstepping cylinder inside has centre bore, is coordinated using small―gap suture between the 3rd cylinder and fuel tank；Product temperature in this device reduction welding process, reduces deformation in fuel tank welding process, and versatility is stronger.
Description
Technical field
The utility model belongs to armored vehicle technique welding technology field, and what is used when being related to a kind of fuel tank to weld preapres for an unfavorable turn of events
Shape dress is put.
Background technology
Our factory produces a kind of fuel tank, year production lot it is big, the work during welding jig is extremely tedious.In welding
In, deform in welding process big, it is impossible to ensure the quality of welding, manpower and materials and very difficult are not only consumed, serious drags
Prolong operation beat, delay production efficiency.
Due to installing piston in fuel tank, its endoporus needs to ensure its cylindricity, deforms in welding process big, it is impossible to protect
Card cylindricity, coordinates between piston and cylinder and produces gap, declines operating pressure in piston cylinder, or oil leak.
Utility model content
The technical problem that the utility model is solved is to provide a kind of anti-deformation device for fuel tank welding, it is ensured that its storage
Welding quality of the oily cylinder in miscellaneous part welding process, especially reduces fuel tank and is store in miscellaneous part welding process
The cylindricity change of oily cylinder endoporus.The welding deformation of fuel tank can be solved the problems, such as.
The technical solution of the utility model：It is a kind of for fuel tank welding anti-deformation device, the device by the first cylinder,
The stairstepping cylinder of the second cylinder and the 3rd cylinder composition；Stairstepping cylinder inside has centre bore, the centre bore conduct
Louvre；Stairstepping cylinder is followed successively by the first cylinder, the second cylinder and the 3rd cylinder from top to bottom；3rd cylindrical circumference diameter
It is slightly less than and circular diameter in fuel tank；The outer circumference diameter of the second cylinder is more than the 3rd cylindrical outer circumference diameter；First cylindrical periphery
Diameter is less than the 3rd cylindrical outer circumference diameter；During welding fuel tank, the 3rd cylinder is positioned in fuel tank, and the second cylinder is located at storage
Oily cylinder at home and abroad, is coordinated between the 3rd cylinder and fuel tank using small―gap suture；Gap uses the f7 grades of tolerance；The material of the device is copper
Or aluminium.
Preferably, the material of the device is copper T2M or aluminium 5A06.
Preferably, the material of the device is the outer circumference diameter respectively 50mm of the first cylinder, the second cylinder and the 3rd cylinder,
80mm,70mm；Center-hole diameter is 30mm.
The fuel tank fixing tool that uses fixes fuel tank, installs fuel tank Anti-deformation device for welding, manually regulation or from
Dynamic regulation welding position is subjected to.
The beneficial effects of the utility model：Welding deformation problem of the fuel tank in welding process is solved, product is improve
The production efficiency of product and the quality of workpiece.Product temperature in this device reduction welding process, reduces change in fuel tank welding process
Shape, versatility is stronger.

Specific embodiment
With reference to the accompanying drawings and examples, the utility model is described in further detail.
A kind of fuel tank anti-deformation device of the present utility model, it includes following sections content：
First：The overall intermetallic composite coating good using heat-conducting effect makes, such as copper T2M, aluminium 5A06；
Second：There is boss using exterior periphery, spacing for carrying out, upper end is multi-diameter shaft shape；
3rd：Centre has centre bore, for processing louvre；
4th：Coordinated using small―gap suture between Anti-deformation device for welding and fuel tank；Gap uses the f7 grades of tolerance；
The lower end major diameter circle diameter of Anti-deformation device for welding circumference is consistent with circular diameter in fuel tank (suitable), store oil
Tolerance uses the f7 grades of tolerance between the diameter and the 3rd body diameter in the hole of cylinder.
As shown in Fig. 2 being processed using T2M materials, boss outer circumference diameter 80mm, central through hole size is C；A=
80mm, B=50mm, C=30mm, D=70mm, fuel tank anti-deformation device lower end larger diameter end (D sizes end) are put into such as Fig. 3 institutes
In the fuel tank for showing, as shown in figure 1, fuel tank anti-deformation device utilizes conduction of heat in fuel tank welding process, will store
In oily cylinder welding process produce heat absorption and be diffused into air, using through hole, store oil tube inner chamber is received in being welded into
The air discharge of thermal expansion, so as to reduce heat, it is ensured that welding pool stabilization.
Adapt to the needs that are installed of panzer fuel tank many sizes.
