Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to the accompanying drawing and specifically
The utility model is described in detail in embodiment.It should be appreciated that specific embodiment described herein is only used to explain this
Utility model is not used to limit the utility model.
Vehicle end welding of underframe tooling as shown in Figure 1, Figure 2, Figure 3 shows mainly includes substrate 1 and cushion block 2, wherein institute
Laminated construction is formed between the substrate 1 stated and cushion block 2, forms the groove of the notch 11 in one end of substrate 1.The cushion block 2, which is located at, to be cut
Mouth 11 the same side of slot and the structure that forms a fixed connection between cushion block 2 and substrate 1.It is described for the dismounting and adjustment convenient for cushion block 2
Cushion block 2 and substrate 1 between preferably by screw 3 form dismountable fixed connection structure.The cushion block 2 is in substrate 1
Upper formation strip groove 21, the strip groove 21 and the groove of the notch 11 are opposite.In general, the cushion block 2 can be set two pieces, by this
Two pieces of cushion blocks 2 are with respect to thirty years of age and form strip groove 21.
When carrying out the weld job of vehicle end chassis using above-mentioned vehicle end welding of underframe tooling, such as Fig. 4, Fig. 5
Shown, specific operating procedure is as follows:
The vehicle end welding of underframe tooling is fixed on vehicle end chassis group weldering operation turntable 7 by step 1,
And make cushion block 2 upward.In order to guarantee stability of the vehicle end welding of underframe tooling in weld job, usually by vehicle end
Substrate 1 in portion's welding of underframe tooling is directly weldingly fixed on vehicle end chassis group weldering operation turntable 7.Substrate in order to prevent
It being interfered between 1 and vehicle end chassis group weldering operation turntable 7, the substrate 1 preferably uses U-shaped structure plate,
Open end forms the groove of the notch 11, as shown in Figure 1.
Step 2, in advance to the draw beam 6 and the progress tack welding of pilot beam 5 in vehicle end chassis.Here tack welding is
Refer to through spot welding mode come so that both draw beam 6, pilot beam 5 realize Primary Location.
Pilot beam 5 is pressed abd fixed on cushion block 2 by step 3.Specifically being turned using the weldering operation of vehicle end chassis group
Pilot beam 5 is pressed abd fixed on cushion block 2 by the compactor 4 in platform 7.Pilot beam 5 is in formal standard weld job in order to prevent
It deforms before and influences its flatness after standard weld job, in general, the cushion block 2 is arranged two pieces, this two
Block cushion block 2 is rectangular configuration plate and arranged in parallel.In addition, the width of the groove of the notch 11 is greater than strip groove 21
Width, and the center line of the groove of the notch 11 and the center line of strip groove 21 is made to overlap.
Step 4 is required according to weld job to draw beam 6 and pilot beam 5, the draw beam 6 and pillow in vehicle end chassis
Beam carries out standard weld job respectively.
Step 5 can polish to welding position after the completion of the standard weld job of vehicle end chassis, complete
After polishing, then flatness detection is carried out to pilot beam 5.
Vehicle end chassis group is cooperated to weld operation turntable 7 by vehicle end welding of underframe tooling to carry out vehicle end bottom
The weld job of frame can increase the anti-deformation of 5 regional area of pilot beam in vehicle end chassis, significantly reduce vehicle
The exceeded probability of happening of the flatness of the pilot beam 5 of end underframe after welding greatly improves the production of vehicle end chassis
The qualification rate of product, and manual labor's cost is saved, improve the manufacture efficiency of vehicle end chassis product.By to buffering
The deflection of beam 5 is counted, after vehicle end welding of underframe tooling comes into operation, the qualification rate of the flatness of pilot beam 5
Up to 100%, realizes and directly exempt from adjusting.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, and should refer to
Out, any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention etc. should all include
