Claims

[Claims for Utility Model Registration] (1) In a lathe with a structure in which two main spindles are arranged in parallel, a moving table 23 provided between both main spindles 4 and 5 and movable in parallel to the main shaft, and a first moving table for driving the moving table are provided. a driving member 24; swing arm members 27 and 35 provided on the movable table and capable of rotating 180° around a vertical pivot shaft 25 at the center of both main shafts and having a length of 1/2 of the distance between the two main shafts; a second drive member 29 that rotates the swing arm member toward both main shafts; a slide arm 34 that is vertically movably provided on the swing arm member and has a gripper member 39 at its lower end that grips a workpiece; An automatic workpiece reversing device comprising: a third driving member that is driven to move the gripper member to a position concentric with the main shaft and a retracted position above the main shaft. (2) The automatic workpiece reversing device according to claim 1, wherein the gripper member has a plurality of rollers 40a capable of concentrically gripping a rotating workpiece and is compatible with bar material specifications.
