  • Patent number: 5591358
    Abstract: A clamping and welding apparatus for properly clamping and welding a pair of sheet materials within a welding station for both confined and accessible clamping and welding areas. When sheet materials or body panels of automobiles arrive in a welding station, the body panels typically have welding locations that are in both accessible and confined areas. In confined areas wherein the operation and maneuvering of the clamping and welding apparatus are hindered, a laser welder is connected to the end of a programmable robotic arm that provides a wide range of movement to the laser welder independent of a clamp. The clamp provides a pair of opposed clamp arms that are pivotally connected to a support member and whose pivotal movement is powered by a pair of clamp actuators units. An aperture is provided through one of the clamp arms to guide and direct the laser welder to a proper position for providing a spot weld on the body panels.

  • Patent number: 5427300
    Abstract: A framing apparatus that accurately and efficiently clamps and welds a loosely assembled vehicle body with a high degree of repeatability between consecutive vehicle bodies while also having the ability to adapt to a plurality of different, predetermined loosely assembled vehicle body configurations in a quick and efficient manner. The framing apparatus provides a first and second framing means that move between a raised position for introducing and removing the vehicle body from a welding station and a lowered position for clamping and welding the loosely assembled vehicle body. The first and second framing means are pivotally connected to a carriage which is supported on a pair of substantially parallel inner rails for movement along a first path of travel. A pair of substantially outer rails support the first and second framing means for movement along the first path of travel when in the raised position.
