Abstract
The invention discloses a welding method for controlling frame assembly deformation. The welding method comprises the specific steps of (1) only welding six points at the bottom of a middle longitudinal beam and six points at the bottom of a rear longitudinal beam at an assembly working position of a left longitudinal beam and a right longitudinal beam; (2) firstly using CO2 welding for completing welding a transverse beam, a propelling rod transverse beam assembly and the like after an engine is installed at a beam frame assembly working position, and then again welding 3*2 points of the lower portion of the side face of the middle longitudinal beam and the lower portion of the side face of the rear longitudinal beam; (3) firstly completing welding other parts at the beam frame assembly working position, and at the moment, under the compression state of a clamp, finally completing welding 2*2 points of the upper portion of the side face of the position where the middle longitudinal beam is connected with the rear longitudinal beam and welding 2*2 points of the upper turn-up side. By the adoption of the welding method, the frame assembly deformation is effectively controlled, the sizes of important parts are stable, matching is good, and positioning of the clamp is reliable.
Description
Technical field
The present invention relates to a kind of welding method of controlling the frame assembly distortion.
Background technology
There is deviation in the hole in piece part position, and the longeron resilience is big, and the part match ratio is relatively poor, and most of part does not reach requirement; Part anchor clamps positioning accuracy, intensity do not reach requirement, interference is arranged and locate unreliable phenomenon; After the roof beam structure assembly welding, on the body in white cubing, left and right sides front longitudinal leading portion warpage 1-1.5mm up 2-3mm, left and right sides floor side member back segment warpage 1-1.5mm up 2-3mm, about in the middle of the longeron 3 planes measure and have only 1-2mm sometimes; Almost all the total Chengdu of roof beam structure are this situations, and best warpage is below 1, qualified fully almost seldom, below 30%.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, welding procedure (welding sequence) is also adjusted, welding procedure is fully analyzed, carry out multivariant test adjustment, sum up optimum process scheme, to roof beam structure deformation effect maximum be the solder joint of beam junction, middle part, a kind of welding method that frame assembly is out of shape of controlling is proposed.
To achieve these goals, a kind of welding method of controlling the frame assembly distortion, the concrete steps of this method are as follows:
Former technology is changed at left-right longeron assembly station 20 solder joints:
(1) longeron and floor side member bottom 6 points during left-right longeron assembly station only welds;
(2) at roof beam structure assembly station, use CO earlier
2Weldering is finished engine welding such as back crossbeam, distance rod crossbeam assembly is installed, and then longeron and bottom, floor side member side 3 * 2 points in the welding;
(3) at roof beam structure assembly station, earlier the miscellaneous part welding to be finished, this moment, part was in theoretical position under the anchor clamps impaction state, 2 * 2 on longeron and top, side, floor side member junction and upper overturning 2 * 2 means of spot welds in finishing at last; After adjusting, reduce deflection to greatest extent.
After the invention has the beneficial effects as follows this method of employing, the strength member dimensionally stable, no-float, the anchor clamps location is reliable, after finally reaching the welding of roof beam structure assembly, on the body in white cubing, qualification rate is more than 99%, maximum warpage control accounts for below 5% below 1mm, and disqualification rate is below 1%.
Description of drawings
Fig. 1 is a kind of welding schematic diagram of controlling the welding method of frame assembly distortion.
The specific embodiment
A kind of welding method of controlling the frame assembly distortion, the concrete steps of this method are as follows:
Former technology is changed at left-right longeron assembly station 20 solder joints:
(1) longeron and floor side member bottom 6 points during left-right longeron assembly station only welds;
(2) at roof beam structure assembly station, use CO earlier
2Weldering is finished engine welding such as back crossbeam, distance rod crossbeam assembly is installed, and then longeron and bottom, floor side member side 3 * 2 points in the welding;
(3) at roof beam structure assembly station, earlier the miscellaneous part welding to be finished, this moment is under the anchor clamps impaction state, part is in theoretical position, 2 * 2 on longeron and top, side, floor side member junction and upper overturning 2 * 2 means of spot welds in finishing at last after adjusting, reduce deflection to greatest extent.
It should be noted that at last: above embodiment is only in order to illustrate the present invention and unrestricted technical scheme described in the invention; Therefore, although this specification has been described in detail with reference to above-mentioned the present invention of each embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the present invention; And all do not break away from technical scheme and the improvement thereof of invention spirit and scope, and it all should be encompassed in the middle of the claim scope of the present invention.
Claims (1)
1. control the welding method that frame assembly is out of shape for one kind, it is characterized in that being: the concrete steps of this method are as follows:
