Wheel attachment aid apparatus in automobile assembly line
First Claim
1. A wheel attachment aid apparatus in an automobile assembly line, comprising:
- a hanger by which a car body is hung and conveyed along said assembly line;
a truck which is disposed so as to be movable along said assembly line sideward of said assembly line;
a synchronous motion unit which is mounted on said truck and which moves said truck in engagement with said hanger and in synchronism with the conveyed car body;
a bed which is mounted on a lower surface of said truck so as to be horizontally movable in a direction intersecting said assembly line;
a pole which is suspended from said bed;
a vertical motion unit which is mounted so as to be vertically movable along said pole;
a flat base plate which is suspended by said vertical motion unit and which has an opening in its central part, an annular sprocket which is supported on said base plate so as to be turnable along an outer periphery of said opening;
a pair of wheel supporting structures which are respectively disposed at front and rear ends of said base plate on a lower side thereof so as to project toward said assembly line and to be turnable about horizontal rotational aces and each of said wheel supporting structures has sprocket mounted thereon;
a handle which is mounted on said annular sprocket and which drives and rotates said annular sprocket and the sprockets of said wheel supporting structures and which drives and rotates said wheel supporting structures through manipulation of said handle; and
an air cylinder which is spanningly interposed between said pole and said vertical motion unit and which has a function as a balancing actuator for folding said base plate in a balanced state in correspondence with a weight of a wheel placed on said wheel supporting structures.

Abstract
In an automobile assembly line wherein a car body is hung and conveyed by a hanger; an apparatus for aid in attaching a wheel in which the wheel is set on a pair of wheel supporting structures (12, 12) at a wheel placement position, a base plate (10) is held in a balanced state by an air cylinder (16) interposed between a pole (8) and a vertical motion unit (9), the base plate (10) supporting the wheel is approximated to a wheel attachment position in the car body (1) while being synchronously moved by a synchronous motion unit (5), and the wheel is moved horizontally and vertically by turning an annular handle (15) with its balanced state kept by the air cylinder (16), thereby to effect the positioning between the wheel and a hub on the car body (1), so that an operator need not directly lift up the wheel.
