A framing system and framing device for assembling and welding a body-in-white. The framing system utilizes completely separate framing and welding operations, which are typically intermixed in conventional framing systems. The framing device is a unitary frame structure within which an underbody, side frames and other body components can each be supported and accurately positioned with respect to each other prior to the welding operation. The framing device includes a cart which serves as the base and main support for the framing device, and an upper body support member. Using an appropriate number of clamping devices, the net positions of the body components which constitute the body-in-white are properly established and maintained, such that gate fixtures are unnecessary during the welding operation. The structure of the framing device provides considerable access to the body-in-white supported within the interior of the framing device, such that a greater number of welding guns can be used during the welding operation. As a result, essentially all of the welds necessary to achieve and maintain the rigidity and geometry of the body-in-white can be formed during a single welding operation. |

DETAILED DESCRIPTION According to the present invention there is provided a framing system and a framing device for the assembly of a body-in-white.
The framing device is structured to enable the final net positions of the individual components of the body-in-white to be established and maintained, such that the entire framing device can be transported from a loading station to a framing/welding station, at which all welding operations necessary to establish a structurally rigid body-in-white can be performed.
The framing device is composed of two support members, the first of which supports the underbody while the second primarily supports and locates the upper body members of the body-in-white, such as the side frames, front and rear headers, roof or roof bows, and the like, relative to the underbody.
The framing device is also structured to optimize access to the body-in-white, such that a relatively large number of welding guns can be positioned to produce the required number of welds necessary to permanently and rigidly establish the final geometry of the body-in-white.
Accordingly, the framing system of this invention eliminates the requirement for toy tabbing the body-in-white prior to framing, and further eliminates the need for maneuverable gate fixtures during the welding operation.
The first and second support members of the framing device are preferably selectively engagable with each other to promote interchangeability and, therefore, flexibility of the framing system.
The support members are provided with corresponding locating members such that their established relative position to each other accurately establishes the necessary net positions of the individual body components of the body-in-white.
Together, the first and second support members define a unitary frame structure which is suitable for transporting the body-in-white to and from a framing/welding station, at which the welding operation is performed.
Consequently, it is an advantage of this invention that the individual body components can be accurately located in relation to each other by the framing device, such that the body components can be welded together to form a unitary body-in-white while being supported by and within the framing device
