ABSTRACT:
A torch cutting machine having a hydraulic motor drive and a hydraulic system for actuating the drive, which system includes a hydraulic liquid flow orienting valve for controlling the direction of movement of the drive, in which the control arrangement for each hydraulic motor involved comprises a stepping or pulse motor assembly mounted on the machine frame for free floating shifting movement longitudinally of the machine trackway, a rack made fast to and extending the length of the trackway, with the stepping motor assembly including a stepping motor and mounting a gear that is driven in forward and reverse directions by the stepping motor and is in rolling meshing torque transmitting relation with the rack. The hydraulic liquid flow orienting valve is in the form of a servo valve secured to the machine frame and having its operating spool connected to the stepping motor assembly for movement thereby. When the stepping motor is driven it effects actuation of the machine hydraulic motor drive it controls by appropriately positioning the servo valve without the stepping motor involved being a direct part of the machine driving mechanism. The disclosure also illustrates the drive control involved as applied to machine tool operation.
