Clamping arrangement for supporting raw castings during processing
First Claim
1. A clamping arrangement for supporting raw castings or other workpieces during processing comprisinghousing means adapted to be connected to a frame;
- a platform rotatably mounted on said housing means about a first vertical axis;
a column secured to said housing means adjacent to, but outside, the periphery of said platform, said column extending along a second vertical axis;
supporting means rotatably mounted on said column about said second vertical axis; and
a clamping lever pivotably coupled to said supporting means to permit said lever to move toward said platform to clamp a workpiece therebetween and away from said platform to release a workpiece, said lever including a guiding means and a telescoping arm slidably mounted in said guiding means to permit said telescoping arm to move along a telescoping axis which is disposed radially with respect to said second vertical axis, said telescoping arm having means mounted thereon for engaging the workpiece.

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.
