Abstract
The invention relates to a combined centering and clamping device that is actuatable by a pressure medium, and is especially useful in auto body building industry. Through this invention, large-area clamping of the work product around the circumference of the centering part is possible. This large area clamping produces not only favorable force distribution but also large-area, reliable centering around the centering part, which allows the work product to be locked together with high precision. This invention is especially advantageous in building auto bodies in the automotive industry.
Claims18
A combined centering and clamping device actuatable by pressure medium, especially for use in auto body building in the automotive industry, including a bolt-like centering part (6) and a clamping part (42, 43), said bolt-like centering part (6) includes a pressure medium-driven motion cylinder (1) with a piston body (12), and the clamping part (42, 43) includes a clamping cylinder (2) with a clamping piston (25), and said motion cylinder (1) and said clamping cylinder (2) being disposed coaxially in line with one another, and wherein the clamping part (42, 43) is supported in a slot formed in said bolt-like centering part (6) and the centering part (6) and the clamping part (42, 43) are driven one after the other in alternation in both directions, to clamp and center or release in response to the application of pressure by said pressure medium.
