Clamping device for positioning of workpieces, machine tool with a clamping device of this type, a method for the positioning of workpieces by means of a clamping device of this type

摘要

A tensioning device (1) for positioning of workpieces with respect to a machining device (3) of a machine tool (2) comprises two clamping elements (5) as well as a for the clamping elements (5) is constructed as a servo drive and actuating drive (9). In order to convert into a functional state, the clamping elements (5) is initially carried out by means of the actuator (9) relative to one another in a spun-output setting to be movable towards one another. In the spun-output setting, a between the clamping elements (5) which is arranged in the workpiece from the clamping elements (5) on the outside, is not subject or with a force, the magnitude is smaller than a of the clamping elements (5) in the operating state on the workpiece clamping force exerted. Starting from the spun-output setting, the clamping elements (5) by means of the actuator (9) to one another and thereby converted into the operating state.A machine tool (2) for machining of workpieces has a clamping device (1) of the above type on.A method for the positioning of workpieces with respect to a machining device (3) of a machine tool (2) is mixed with a clamping device (1) is carried out of the above type.For the operation of the clamping device (1) is a computer program, which, according to one method, in the context of the corresponding control commands are generated, is created. Coding means for generating said control commands are provided on a computer program product.
