Description
Technical field
This utility model belongs to technical field of welding equipment, is related to a kind of welding of tank body of oil tank, and more particularly, to one kind exists
The fixture of oil filling pipe is welded on tank body of oil tank.
Background technology
As industrial important industry, with expanding economy in recent years, automobile market expands automobile industry, and automobile produces
Industry fast development.This all proposes higher requirement to the production of fuel tank in production capacity, and product quality.The major function of fuel tank is used
In holding fuel oil, thus oil filler and oil-out generally need to be provided with the casing of fuel tank, at this oil filler, be connected with oiling
Pipe, for refueling in the casing to fuel tank；It is connected with, at this oil-out, nut of draining the oil, be can achieve from fuel tank by this nut of draining the oil
Casing in drain the oil.
So, weld corresponding oil filling pipe and nut of draining the oil in the welding process of fuel tank it is necessary on fuel tank.And
Be welded with fuel tank oil filling pipe and drain the oil nut when, be generally accomplished by the fixture of some welding so that oil filling pipe and drain the oil spiral shell
Female welding is convenient, quick.
The application for a patent for invention of Application No. 201310700841.9 discloses a kind of oil sump fuel outlet and drains the oil nut
Attachment structure and apparatus for welding and positioning, this apparatus for welding and positioning includes base plate, upper end has inclined-plane and the upper end of lower end and base plate
The arc supporting post of mode connects for screw and two oil sump side locating pieces with the upper end mode connects for screw of base plate；Base plate has three
Alignment pin；Inclined-plane has rectangle counterbore；Two relatively short sides of rectangle counterbore respectively have a upper surface and are less than propping up of inclined-plane
Supporting block.This oil sump fuel outlet drain the oil nut connecting structure connect when, another side of two legs is respectively put in a rest pad
On, flange is located on the upside of baffle plate and flexure strip, and the other end of nut of draining the oil stretches out outside through hole through through hole, and oil sump is placed on welding
On positioner, two locating pieces respectively block a side of oil sump two adjacent side, and three alignment pins respectively insert oil sump
One location hole, the fuel outlet at oil sump base angle pushes down flange, then welds inside leg and oil sump on welding machine
Connect；The small end of oil discharge screw be connected through fuel outlet with nut thread of draining the oil and oil discharge screw big side pressure live oil sump outside
Sealing.
In prior art, the welding of oil filling pipe is generally welded using human assistance, does not have special to be applied to refuel
The fixture of sealing of tube.But it will usually use the positioner of some oil filling pipes in welding.As Application No.
201520014055.8 utility application discloses a kind of fuel tank oiling tube positioning structure, and this fuel tank refuels
