Title: Improvements in or relating to machine tools
IPC: B23Q11/00
Filed: 1957-10-10
Abstract: 822,120. Sockets. SOC. GENEVOISE D' INSTRUMENTS DE PHYSIQUE. Oct. 10, 1957 [Nov. 12, 1956], No. 31736/57. Class 83 (3). In a machine-tool, a tool-holder spindle has a tapered tool-holding socket and electrical means for clamping or ejecting the tool. The hollow spindle 1 is rotatable on bearings 2, 3 in a quill 4 which is displaceable axially, in a frame 6, by a pinion 7 and a rack 9 on the sleeve 4. The spindle is rotated by a motor driven by a pulley 11 rigid with a sleeve 12 rotatable in bearings 13, in the frame 6. The sleeve 12 has internal splines 14 engaging splines 15 on a sleeve 16 driving a cylinder 17, through teeth 18, 19, cylinder 17 driving spindle 1, through teeth 20 thereon engaging teeth on a sleeve 22 keyed to the spindle. A spring 75 maintains sleeve 16 in the upper position shown. A tapered-socket 28, in spindle 1, receives a toolshank 29, and a rod 31, displaceable axially and angularly within the spindle, is threaded at 32 for engagement with a threaded hole 33 of the tool. The rod 31 is journalled at 37 in the spindle and is partly supported by a spring 39. To rotate the rod 31 and thus clamp or eject the tool, a non-circular extension 45, of rod 31, is connectable to a socket 44 on a hollow spindle 53, rotatable in a bearing 65, either through friction discs 57, 58 (for clamping a tool) or by a uni-directional roller-clutch 62 (for releasing the tool), from a worm-wheel 54 whose worm 56 is driven by an electric motor M. In operation, to release a tool 29 from the socket 28, the quill 4 is raised to lift spindle 1 and cylinder 17 above the position shown, thus disengaging teeth 18 from teeth 19 on sleeve 16 and engaging teeth 86, 87 to hold the spindle against rotation, the end 45 of rod 31 is also engaged in socket 46, so that the operator may start motor M through a switch 83. Rod 31 also pushes up a pin 90 in shaft 53, to immobilize a relay-switch 91, 70 in the circuit of motor M to prevent reverse rotation thereof. The motor M drives shaft 53 and rod 31 to unscrew the latter from the tool-shank, upward movement of spindle 1 being limited by a fixedring 82, and of rod 31 by a collar 41 thereon. When rod 31 is unscrewed, the operator stops motor M by switch 83, and lowers the quill 4 to its normal position, as shown. To insert a tool, with the quill 4 in its raised position, the operator pushes the tool into socket 28, thereby raising rod 31 and compressing a spring 39, to cause the end 45 of the rod to raise the pin 90 and actuate 91, 70, thus starting motor M in reverse direction to rotate rod 31, through friction-clutch 58, and screw it into the tool at 32. When the tool engages the socket 28, rod 31 is drawn downwards to engage its collar 34 with the spindle 1 for final tightening, the rotation of motor M being maintained by a bimetallic-strip time-relay 72, and after tightening, the clutch 58 slips until the motor is stopped by relay 72. The quill 4 is then lowered to operative position.
