Workpiece holder with retaining pins

摘要

The holder has an open pressure chamber (17) on the back side of the retaining pins (3) facing away from the workpiece. A pressure medium can emerge from the pressure chamber onto the respective workpiece through the free spaces between the pins. The retaining pins are constructed from commercially available cylindrical pins with threaded holes (29) at the back. The clamping frame enclosing the retaining pins has a rectangular, and especially square, internal dimension.
