Hydraulic multi-part clamping apparatus for e.g. repeatable positioning long-shaft or rod-shaped workpieces, in horizontal position on e.g. machine tool, has tensioning drives arranged along rail transport for clamping rods of jaw via wedge

摘要

The apparatus has a ball, roller or slide bearing-led seem-embracing recess fitting to a cross-sectional shape, dimensioning a conveyor rail (7) and introduced at an underside. Hydraulic actuators for axially directed insertion and adjustment of workpieces (19) are acted at connection struts (2) of a support frame (1) or at a device base plate parallel to a workpiece longitudinal direction in a horizontal manner. Hydraulic tensioning drives (10) are arranged along a rail transport (7) for clamping two associated tie and push rods (15) of a jaw (4) via a double wedge (13).
