Abstract
1,073,548. Machine tools. GIDDINGS & LEWIS MACHINE TOOL CO. March 22, 1965 [July 30, 1964], No. 12020/65. Headings B3B, B3C, B3K and B3T. [Also in Division F2] A machine tool comprises a spindle bar 14 axially-movable in a sleeve 15 and means 82, 83 for positioning the bar. Resilient means clamp the bar in the sleeve and an actuator is provided in the sleeve for unlocking the bar. The spindle bar supports a tool 16 and is carried by a headstock 11. The tool is changed by a transfer arm 34 co-operating with a shuttle on a track 33 leading to a magazine 32 which is moved on a column 31. The spindle sleeve 15 is rotated by a motor 49 and gears 48, 47, the latter being secured between bearings. 42, 43 in a cartridge 41 forming part of a complete spindle and bearing assembly unit. The unit is locked in place by expansion of the cartridge 41 when a pre-loading force is applied to the bearings by a nut 45. Oil flung off by slinger rings 15a drains through a hole 54. The bar 14 is locked by forcing the tongues 61 of a sleeve 60 against the bar by means of dished washers 62, 63 flattened by rods 72 under the action of springs 69. The resulting toggle-action clamping force is released by an annular piston 75. When unlocked, the bar 14 is positioned axially by the selective operation of the valves 83 causing the pistons 82 to move a pinion 85 engaging a fixed rack 86 and a rack 87 on a non-rotating rod 80 connected to the bar by a rotary coupling 80a. The bar is positioned angularly for toolchanging by an hydraulically-operated plunger 92, Fig. 7 (not shown), which is projected into a recess 91 in a collar 71 keyed to the sleeve 15 to which the bar is also keyed. Two proximity switches 95, 96 co-operate with projections on the collar 71 to cause the spindle drive to slow and then stop. When the plunger 92 is operated, a piston 102, Fig. 5 (not shown), is forced against an aperture in a fixed member adjacent the sleeve 15 to allow fluid to be supplied to the clamp-releasing piston 75. The machine may be tape-controlled as in Specification 986,570.
