Method and apparatus of assembling vehicular body
First Claim
1. A method of assembling a vehicular body wherein a pre-tack welding operation is carried out by positioning each of a floor main, a right body side, a left body side and a roof rail which constitute a body main component of a vehicle while by making a relative positioning between the floor main, the right body side, the left body side and the roof rail, the method comprising the following operations:
- positioning the floor main and making the relative positioning between the floor main and the body side'"'"'s lower section, by using a three-dimension general locator device standing on a floor, and positioning each of the right body side, the left body side and the roof rail and making the relative positioning between the body side'"'"'s upper section and the roof rail, by using a front body side upper section locator jig and a rear body side upper section locator jig which are disposed on a ceiling and independent of each other in a forward-and-rearward direction of the vehicular body, and each of which is replaceable in accordance with a type of the vehicle.

the front body side upper section locator jig and the rear body side upper section locator jig are for a single type vehicle or a plural types of vehicles, each of the front body side upper section locator jig and the rear body side upper section locator jig for the type of the vehicle is stored in a storage area in a vicinity of an actual operating position, and each of the front body side upper section locator jig and the rear body side upper section locator jig is replaceable between the operating position and the storage area, in accordance with the type of the vehicle to be assembled. -
3. The method of assembling the vehicular body as claimed in claim 2, wherein
the front body side upper section locator jig locates a front section of the vehicular body, the rear body side upper section locator jig locates a rear section of the vehicular body, the rear section being more likely to vary in molding shape than the front section with a difference in the type of the vehicle, and the front body side upper section locator jig is smaller in total number than the rear body side upper section locator jig.

4. A method of assembling a vehicular body, comprising the following operations:
-
a temporary assembling operation of temporarily making a relative positioning between a floor main, a right body side, a left body side and a roof rail which constitute a body main component of a vehicle, a pre-tack welding operation by positioning each of the floor main, the right body side, the left body side and the roof rail while by making the relative positioning between the floor main, the right body side, the left body side and the roof rail, and an additional welding operation of the body main after the pre-tack welding operation, wherein the body main component is conveyed between the operations in such a manner that the body main component is carried on a pallet having such a function as to position and clamp the floor main, in the pre-tack welding operation, a three-dimension general locator device standing on a floor lifts up the body main component including the floor main and makes the positioning, thereby implementing the pre-tack welding operation with the body main component separated from the pallet, and in the additional welding operation, the pallet is positioned in a pallet positioning apparatus, and the body main which is positioned and clamped by the pallet is subjected to the additional welding operation. - View Dependent Claims (5)
