Abstract
807,375. Turning, milling, &c. machines. C.O.V.E.M.A. CONSTRUCTION ET VENTES DE MACHINES. Jan. 9, 1966 [Jan. 10, 1955], No. 665/56. Class 83 (3). A machine-tool having a vertically-slidable head carrying mechanism for driving the work or a tool such as a milling-cutter, and also for feeding a saddle, has an hydro-pneumatic unit for balancing and supporting the head on guides which are carried laterally of a lathe-like bed. The milling-cutter may be mounted in the headstock spindle, or on an arbor 57, Fig. 4, supported by the spindle and a vertically-adjustable outboard bearing 58. Graduated scales facilitate the adjustment of headstock and bearing. The headstock 22 is moved vertically on guides 23, 24 by a screw 92 attached thereto, co-operating with a nut driven by gearing in a box 20. Counterbalancing is by a plunger 122, Fig. 14, on the headstock, sliding in a fixed cylinder 117, open at the bottom and communicating with fluid 112 acted upon by compressed-air in a casing 111 attached to the machine bed. The air-pressure is adjusted, as by a hand pump, to suit the weight of the attachments on the headstock. Driving-gear and feed-motions.-The headstock-spindle 25, Figs. 3 and 4, is driven by a motor through a clutch and change-gear controlled at 32, 33. The spindle drives a feed-box 21 which drives, through a cardan-shaft 41, a further box 20 on the machine bed. Box 20 drives, through a clutch, the feed-screw 17, and also drives a feed-shaft 16, and has a wormdrive for the nut of the headstock-elevating- screw 92. The transverse feed-screw for slide 45 drives, through a clutch, a nut splined on the feed-screw for the milling-slide 60. Slide-rests.-The angularly-adjustable slide 60 is supported on surfaces 129-132, Fig. 9, on saddle 14 and is centred at 134. Locking in any angular position is effected by bolts in bosses 129-130 engaging an arcuate T-slot therein and drawn downwardly by tapered set-screws 138, Fig. 12, engaging wedge-shaped recesses in the bolts 136.
