A clamping jig particularly adapted for use with elongate work pieces. The jig has an elongate work face, a work stop abutment the length of the work face, a plurality of toggle clamps affixed to the work face. One or more elongate or linear work pieces to be worked are positioned on the work face and held in place by the work stop abutment. The plurality of toggle clamps may be used to either hold the work piece in place or hold one or more additional work pieces to the first work piece. The work face or faces are rotatable around the elongate axis. Each toggle clamp has a toggle clamp arm with which the toggle clamp is set. On rotation of the work face, an actuating bar engages the toggle clamp arms to release the toggle clamps for removal of the work piece.
A device for positioning components to be joined together, such as car body components, is characterized by at least one movable central module and a plurality of arms, movable in space and connected thereto and which in each case have at least one holding element for holding the components. By means of the inventive method for the positioning of the components to be joined together and for the performance of which the said device is particularly suitable, the components are held from a position within a desired arrangement of the components to be joined. In this way the assembled components during a subsequent tacking together and optionally further downstream production processes such as welding or the like, are accessible in optimum manner from the outside. Further advantages of the method according to the invention are a limited space requirement and possible balancing of the production process.
