A system for positioning an automotive vehicle side body wherein slide rails for supporting a sliding conveyor for movement thereon in an automotive vehicle body assembly line is located, not on a floor of the assembly line, but at the same height as an underbody supported at a elevated location above the assembly line floor, so that an open space below the slide rails can be used for installing other necessary equipment.

System for positioning automotive vehicle side body

A vehicle body positioning apparatus includes a first jig for an under body, which is located and fixed on a jig surface plate provided in a vehicle body assembly equipment, second jigs for right and left side bodies, and a third jig for upper body parts which are carried by an overhead conveyor. An arched frame, is erected on the jig surface plate perpendicular to an assembly line. A positioning and supporting assembly is provided on the arched frame and the second jigs, respectively, so as to position the third jig with respect to the first and second jigs.

Apparatus for positioning vehicle body in assembly line

A spot welding device for welding car bodies at a plurality of different positions without the need to move the car body to the welding device for each weld position. The device comprises a polyhedron shaped rotating member having a plurality of electrodes disposed on surfaces of the rotating member. The member is rotated to select a desired surface and the configuration of electrodes thereon to thereby perform a plurality of welds with the electrodes on the selected surface.

Spot welding device

A jig assembly for a car body including a movable jig unit having a frame with a universal configuration and removable jig members configured exclusively for a distinctive body part; and a fixed station jig unit for positioning and fixing the movable unit. The fixed unit is comprised of an elevator lifter for supporting the frame, reference pins which are provided in the elevation range of the lifter and are inserted into the frame to position the frame in the longitudinal direction, reference blocks for positioning the lower end of the frame, first clamp units for fixing the frame onto the reference blocks, and second clamp units for securing a body part to the jig members.

Jig for car body assembly

An apparatus for transferring a driving force to a jig unit, comprising a plurality of fixed station coupling assemblies mounted on a support member, each assembly having a fixed station connector to which a driving force transfer means is connected; a jig unit coupling assembly mounted on a jig unit is provided to move in the direction of the fixed station coupling assembly for connecting the unit side connector to the fixed station connectors to feed a driving force to the jig unit; an actuating means is provided on one of the fixed and unit side coupling assemblies to move a respective connector in the direction to secure both fixed station and jig unit connectors in a connected position; and an engaging means holds both the coupling assemblies at a proper position by engaging locking parts provided on both coupling assemblies.

Apparatus for transferring a driving force to jig unit

A beaded edge is formed on a plate member, which has an upstanding outer edge bent with a predetermined radius of curvature, by placing the plate member on a lower die and applying a uniform force against the free edge of the upturned portion at an approximately 45.degree. angle to turn the outer portion inwardly to form an angle of about 45.degree. with the plate member, and then pressing the free edge downward into contact with the plate member while maintaining a substantially constant curvature of the bend region to produce a beaded edge.
