If all wears beam 202, makes respectively to wear beam 202 on the basis of the side bar 201 in left side to be aligned on 2 length direction of main body of vehicle frame and go forward side by side
Row spot welding；Finally, the assembly of right side side bar 201 is carried out, similarly, using six positioning and clamping mechanisms 5 on right side to the side bar
201 are positioned, and beam 202, side bar 201 are respectively worn in spot welding, so far complete in 2 roof side rail 201 of main body of vehicle frame and wear the spelling of beam 202
Dress.
Further, main body of vehicle frame 2 send part by moving trolley, in order to facilitate moving trolley send part, Auxiliary support platform 33
Side there is the trolley easy to remove of being open to travel to assembly jig, convenient for being connected for platform position and moving trolley, improve object
Flow percent of automatization；Meanwhile front support platform 31 and the supporting surface of rear end support platform 32 height are adjustable.Main body of vehicle frame 2 is in shifting
Height on dynamic trolley apart from ground is higher than height of the assembly jig assembly jig position apart from ground, and moving trolley lifts main body of vehicle frame 2
After walking in place, the support of front support platform 31 and rear end support platform 32 is lifted upwardly, is lifted workpiece and is continued to lift later
The height that slightly above moving trolley lifts main body of vehicle frame 2 is risen to, fitting is completed and moving trolley is exited into spelling along original route simultaneously
Fill platform position.
Further, the positioning and clamping mechanism 5 of every a side is when positioning side bar 201 on assembly jig, gripping block
51 and gripping block 52 can both clamp side bar 201, additionally it is possible to after clamping by the side bar 201 towards 2 direction of main body of vehicle frame level
It is mobile, so that side bar 201 be made to be bonded with main body of vehicle frame 2, splice convenient for spot welding；Meanwhile being also convenient for the peace of assembled front side beam 201
Dress.
Further, the positioning and clamping mechanism 5 of every a side, can be with when positioning to side bar 201 on assembly jig
It is pressed downward pilled-in selvedge beam 201 by hold-down mechanism 58, preferably positioning is fixed to realize.
Further, be equipped with gasket 6 in front support platform 31 and rear end support platform 32 so that main body of vehicle frame 2 it is upper
Wing plate 211 is positioned on the gasket 6, also has gasket 6 between the gripping block 51,52 of positioning and clamping mechanism 5, so that with assembled side
Beam 201 is positioned on gasket 6.
In other embodiments, the quantity of Auxiliary support platform 33 is not limited to two in this implementation, can also be according to reality
Situation is increased and decreased.
Main body of vehicle frame is carried out what positioning avoided occurring when fitting by centering positioning mechanism by vehicle frame assembly tooling of the present invention
Error, positioning and clamping mechanism carry out multiple spot clamping to side bar, had both improved the assembled rigidity of side bar, and also provided side bar, Chuan Liang
Splicing accuracy and assembled efficiency.
Although describing the present invention with reference to the above exemplary embodiment, it is to be understood that, term used be explanation and
Term exemplary, and not restrictive.Due to the present invention can be embodied in a variety of forms without departing from invention spirit or
Essence, it should therefore be appreciated that above embodiment is not limited to any of the foregoing details, and should be defined by the appended claims
The whole change and modification widely explained, therefore fallen into claim or its equivalent scope in spirit and scope all should be with
Attached claim is covered.
