Abstract

The present invention provides an automatic assembly system, without using an expensive sensor, to enable an assembling jig to be easily positioned with respect to a particular portion of a car body to which parts are to be assembled, in order to facilitate assembling of the parts while reducing production cost. The basic car-body positioning arrangement preferably includes a reference hole, used for positioning, and a seating piece, used for jacking-up the car body.

Claims

1. An automatic assembly system for assembling parts to a car body in which an assembling jig, mounted on an automatic machine, is used to assemble said parts to said car body, said system comprising:

basic car-body positioning members provided on a bottom portion of said car body, said basic car-body positioning members include,

a reference hole provided, exclusively for positioning use, on an underside of a rear end portion of each of a pair of left and right front side frames of the car body, and

a seating piece for jacking-up the car body, said seating piece being attached to each of the front and rear end portions of the underside of the car-body side sills to be accurately adjusted in position, so that the car body is positioned longitudinally and laterally by said reference hole and is positioned vertically by said seating piece; and

locator holes for the assembling jig formed in a region of a particular portion of the car body to which said parts are to be assembled;

wherein, said car body being manufactured through maintaining control of relative positional accuracy with respect to each of the basic car-body positioning members and the locator holes, wherein said car body being positioned by using said basic car-body positioning members and, by using the locator holes, the assembling jig is positioned with respect to the particular portion of the car body to which said parts are to be assembled to ensure an accurate assembling of said parts to the car body.
