摘要： An automotive framing apparatus with a support frame having a frame roof supported above a generally horizontal support surface. At least four gate assemblies are carried by a carrousel supported on the frame roof for rotational movement around a common vertical axis and form two gate assembly pairs of diametrically-opposed gate assemblies. The gate assemblies of each gate assembly pair are supported for pivotal movement between generally horizontal stowed and generally vertical working positions. A rotary drive selectively positions one gate assembly pair at a time in a framing position from which the two gate assemblies of the selected gate assembly pair can be pivoted by a drive downward to respective diametrically opposed working positions on opposed sides of a vehicle body to be welded.

摘要： An indexing drive has an actuator which reciprocates a ratchet arm along an arcuate path to cause an indexed rotation of rollers during one direction of movement of the ratchet arm which bear on a follower to produce an associated indexed rotation of the follower which may be communicated with a drive mechanism of apparatus to provide an indexed movement of the apparatus. Desirably, when the follower is not being rotated by the rollers, it is restrained from rotation in either direction to prevent movement of the drive mechanism to which it is connected and hence, to prevent movement of the apparatus associated with the drive mechanism.

摘要： A clamp having a pneumatic cylinder with an actuating rod connected to one end of a drive arm which has its other end attached to a crankshaft which in turn has crankpins eccentrically mounted thereon to drive inner and outer clamp arms between retracted and advanced positions corresponding to open and closed positions of the clamp. The length of the drive arm, the extent to which the crankpins are offset from the crankshaft, the specific portion of a quadrant through which the crankpins are rotated, and the distance between the application of the force to the clamp arms and the axes about which the clamp arms pivot all provide a significant mechanical advantage and an extremely large clamping force from relatively low pressure compressed air supplied to the pneumatic cylinder.
