Apparatus for positioning a cutting tool or a cutting unit

摘要

An apparatus for positioning a cutting tool or a cutting unit has a slide (1), a drum (2) mounted on this slide (1) and having a number of adjustable stops (4), a fixed counter stop (7), and a device for rotating the drum (2) with which the stops (4) can in each case be orientated in alignment with the counter stop (7). In order to reduce the centrifugal mass of the moving parts, the susceptibility to trouble and the mechanical and electrical complexity at the device for rotating the drum (2), the latter has a cylinder-actuated ratchet drive (10) which is controlled via non-contact limit switches which scan markings indicating the respective drum position. <IMAGE>
