Device for fixing workpieces in milling machines has tension bar with block suction member movable along bar by drive device having coupling locally fixed on bar

摘要

The device for fixing plate-like workpieces has a tension bar (10) with block suction member (12) moved along the bar by a drive device (22) such as a cable pulley or belt drive which has a coupling (38) locally fixed on the bar and through which the drive which moves the drive device and/or a positioning device can be coupled. Where several block suction members are provided, each one has a drive device and each drive device has a coupling. The coupling has a drive wheel which is rotationally clamped between two holding plates and is pretensioned towards one of the plates so that it bears by an end side against this plate.
