A car side panel assembly line capable of increasing a productivity by shortening an operation time and having a set station ST, a welding station ST, and a next operation station STdisposed in series in this order, comprising a set carriagehaving, thereon, a set jigcapable of holding the side panel W in upright attitude from the side and installed reciprocatingly between the set station STand the welding station STand a frame carriagehaving a lower frameand an upper frame, capable of holding, between both frames, the side panel W in upright attitude through clamp members () mounted on the frames, installed reciprocatingly between the welding station STand the next operation station ST, and allowing to exchange the side panel W with the set carriage.

Side panel assembly line

On a setting cart which is movable back and forth between a setting station and a vehicle body assembly station, there are provided floor panel setting members, side sill receiving members and side panel forcing members which force side panels toward a floor panel from a lateral outward. In the setting station, the floor panel and the side panels which are set in position on the setting cart are transferred to a jig which is disposed in a side portion of the vehicle body assembly station. The side panels are welded to the floor panel by welding robots which are disposed at a level below the jig. In the above-described arrangement, the side sill receiving members and the side panel forcing members are set on the setting cart so as to be retractable into shunted positions free from interference with the welding robots in welding operation. The welding work by the welding robots can thus be started without waiting for the returning of the setting cart to the setting station.

Apparatus for assembling vehicle body

A stud welding apparatus has a welding jig, guide frames and a cartesian coordinate type robot. This robot has a travelling frame, a robot main body, an elevating arm and a stud welding gun. Power supply passages are provided on the travelling frame, the robot main body and the elevating arm, respectively, such that electric power can be supplied from a welding power source to the stud welding gun via these power supply passages. The power supply passage provided on the travelling frame is formed in a first power supply bar which is fixed to the travelling frame and is elongated in a horizontal direction. A pressure type first power supply joint is provided on the robot main body and urges a contact member to be connected to the power supply passage provided on the robot main body into contact and away from the first power supply bar by means of a cylinder. The power supply passage provided on the elevating arm is formed in a second power supply bar which is fixed to the elevating arm and is elongated in a vertical direction. A pressure type second power supply joint is provided on the robot main body and urges a contact member to be connected to the power supply passage provided on the robot main body into contact and away from the second power supply bar by means of a cylinder.
