Abstract

A machine tool construction, comprises, a support frame which has a bar portion extending in one direction, for example, a longitudinal direction, with a gear rack defined thereon, and with a carrier guide movable along said bar portion and having a drive motor for its movement with a pinion which is engaged on the rack to effect the motion. A work carrier is similarly mounted in the carrier guide for movement at right angles to the axis of the bar and it is driven by a separate drive motor driving through a pinion and a rack defined on the work carrier. At least one work holder is mounted for slidable movement along the work carrier and it may be locked to the work carrier against movement and transported by movement of the work carrier or it may be released from the work carrier. In addition, a locking device is provided for locking the work carrier in a fixed position and it may be carried either by the frame of the machine itself or by the carrier guide. The locking device includes a locking member which may be forced downwardly into a locking recess defined on each work holder, only when the work holder is located directly below the locking element. When the work holder is loc…
