Title: Machine tool
IPC: B23B13/12
Filed: 1971-06-02
Abstract: 1336365 Bar stock feed; turret lathes WARNER & SWASEY CO 2 June 1971 [11 June 1970] 18583/71 Headings B3B and B3T [Also in Division G3] A machine tool for operating on bar stock 20 in a work area 52 thereof comprises chuck means 16 for holding the bar stock, gripper means 56 for gripping the bar stock, means for moving said gripper means 56 away from said chuck means to pull the bar stock 20 from said chuck means into the work area, and control means for interrupting movement of said gripper means away from said chuck means in response to the feeding of a predetermined length of bar stock into the work area, to operate the chuck to grip the bar stock, and to continue movement of the gripper means to separate it from the bar stock. Machine tool details.-The machine tool comprises one or more spindles 14 having the chuck means 16. A turret 36 includes a gripper means 56 in the form of expansible resilient fingers 62. The turrent also includes various tools 34. Alternatively the gripper means may be mounted on an assembly separate from the turret. The turret is mounted on a cross-slide on a saddle 48 which is movable on ways 50. The cross-slide and saddle are moved by lead screw drivers driven by servomotors (Fig. 3, not shown). A separate parting-off tool (54) is mounted on a slide adjacent the chuck means. Machine tool control.-A tape (80) and reader (82) feed a programmed sequence into a numerical control system (86). Signal generators (108), (122) on the lead screw drivers produce signals of the position of the gripper means 56 laterally relative to the axis of the bar stock and longitudinally along the said axis. The actuation of the chuck means and the parting-off tool are controlled through the tape control. The position of the gripper means may be monitored by counting pulses generated through its movement. Different lengths of bar stock may be machined in succeeding operating cycles. Instead of stepping on the tape (80) at each successive step of the bar stock an alternative, more continuous, control is provided by control circuit (170) (Fig. 5, not shown). The "gripper engage", "gripper feed" and "gripper disenengage" positions is set, either by the tape or manually, in registers (172), (174), (176) and, through the circuitry, when an error signal reduces to zero as the gripper means reaches a desired position, a null detector (214) switches a counter (182) to select the next required control stage of a programme.
