ABSTRACT:
A clamping arrangement to firmly clamp workpieces of variable shape to permit the workpieces to be processed on all peripheral sides includes a rotating platform and a clamping lever. The platform and the lever are separately mounted on the housing of the clamping arrangement. The lever is mounted on the housing by means of a column and a bearing part. The column is fixedly secured to the housing. The bearing part is rotatably and adjustably connected to the column to permit the bearing part to be located at various positions along the length of the column. The clamping lever is pivotably coupled to the bearing part and may be driven by fluid pressure operated cylinders between clamping and releasing positions. The clamping lever has two telescoping parts to permit the portion of the clamping lever which engages the workpiece to be radially adjustable with respect to the column. When the clamping lever is actuated, the workpiece is secured between a conical clamping peg at the free end of the clamping lever and supports on the rotating platform.
