Title: Control of main-shaft revolution in machine tool
Inventor: TAGUCHI MASAYUKI
IPC: B23Q5/12
Filed: 1983-12-27
Abstract: PURPOSE:To increase and decrease the number of revolution of a main shaft by inserting a nonuniform-speed universal joint between the main shaft and a driving source, permitting the relative angle between the input and output sides to be varied, and properly verying the relative angle during the revolution of the main shaft. CONSTITUTION:A nonuniform-speed joint 4 is inserted between the output shaft 2a of a transmission mechanism 2 and a spindle 3, and the angle alpha formed by the shaft 2a and the spindle 3 is arbitrarily increased or decreased by fixing the slide of a prime motive shaft onto a guide supporting part 7 by a hydraulic cylinder 8 and through the advance and retreat of a cylinder rod 8a. Even if the prime motive shaft performs uniform-speed revolution, the speed of the spindle 3 for a trailing shaft increases and decreases 2 times during one revolution of the prime motive shaft, and the degree of the above-described variation increases as the cross angle X increases. Therefore, if the angle alpha is varied periodically or nonperiodically, the revolution speed of the spindle 3 can be arbitrarily varied within a prescribed range per revolution.

Filed: 1989-09-22
Abstract: PURPOSE:To prevent damage to a foreign material inserted inbetween and a shutter itself by providing a means sensing a change in the interval between a shutter plate and a drive means when the shutter plate is driven in the closing direction to output a control signal of the drive means. CONSTITUTION:When a drive belt 259 is driven in the closing direction to raise a mount block 263, a carrier block 261 is lifted up by the mount block 263 via a coil spring 265 and a shutter plate 253 is being elevated. When a foreign material 271 is inserted between an opening 8a and the shutter plate 253, a load is exerted to the shutter plate, the coil spring 265 is contracted, link rod 262 is projected downward from the mount block 263 and the interval between the carrier block 261 and the mount block 263 is decreased. Thus, the position of the hole of a light shield plate 267 is deviated to shut the optical path of a sensing means 266 and a motor 256 is stopped or reversed by a signal from the sensing means 266. Thus, even when the foreign material 271 is clipped by the shutter plate 253 in operation, a force exerted to the foreign material 271 inserted inbetween is decreased.
