Abstract
748,420. Multiple - spindle drilling &c. machines. LINSTEDT, B.. July 29, 1953 [Aug. 1, 1952], No. 21001/53. Class 83 (3). A vertical multi-station machine-tool comprises a rotatably indexable turret 3, Fig. 1, carrying work-holders 4 for the workpieces 15, the holders projecting from the turret periphery and each being rotatably-adjustable about an axis radiating from the turret axis. Toolspindles 5 are located around a bed 2 at the work stations, one station being free for the loading and unloading of work, and are movable upwardly to operate on the work, each spindle being driven by a motor 6 through feed-means 20. Each holder has a disc 8, Fig. 2, with peripheral locking-notches 8a engageable by a spring-loaded plunger 9, and a toothed disc 7 meshing with pinions 14 driven by racks 10. Follower-rollers 10a on the racks, and rollers 11a on levers 11 for operating plungers 9, coact with cams 12, 13, respectively, fixed to the bed, so that as the turret is indexed from one station to the next, the plungers are withdrawn, the holders are angularly adjusted and the plungers re-engaged. The workpieces are clamped by jaws 23 actuated by hydraulic piston-and-cylinder mechanism controlled by levers 24. A protective hood 22 prevents the scattering of swarf and cooling liquid.
