摘要： PURPOSE:To prevent automatic machining work from generating a failure while a tool from damage, by holding the tool so as to race for a main spindle, if excessive torque of predetermined value or more is applied to the cutting tool during its machining in a machine tool, and detecting abnormality of the tool. CONSTITUTION:A torque limiter 1, holding a tool 13, is mounted to a machine tool main spindle 20, performing cutting work. If excessive torque is applied to the tool 13, it rotates at a speed lower than that of the main spindle 20 or stops by racing the main spindle 20 and a torque limiter main unit 11 for a tool supporter 12. As a result, the tool 13 relaxes its excessive stress. This is because a ball 16 is dislocated from a recessed part 15 in the tool supporter 12 continuing to rotate and repeats to advance into the next recessed part 15, and a vibration is generated when this ball 16 advances into the recessed part 15. A device, converting this vibration into an electric signal by a vibration detector 2 and inputting the electric signal to a comparator 6 through an ampli fier 3, band pass filter 4 and an envelope detection circuit 5 to be compared with a preset value, detects abnormality of the tool 13.
摘要翻译：目的：为了防止自动加工工作在工具损坏时发生故障，通过握住工具以使其与主轴相对，如果在机床加工过程中对切削刀具施加预定值以上的过大扭矩工具，并检测工具的异常。构成：将保持工具13的扭矩限制器1安装在机床主轴20上，进行切削加工。如果对工具13施加过大的扭矩，则以比主轴20低的速度旋转，或者通过使主轴20和用于工具支撑件12的转矩限制器主单元11的摆动而停止。结果，工具 13放松它的过度压力。这是因为球16从工具支撑件12中的凹部15脱位继续旋转并重复进入下一个凹部15，并且当该球16进入凹部15时产生振动。一种装置通过振动检测器2将该振动转换为电信号，并通过放大器3，带通滤波器4和包络检测电路5将电信号输入到比较器6，以与预设值进行比较，检测异常工具13。

摘要： PURPOSE:To prevent variation in revolutional torque of a ball screw system and production of a backlash thereof by dividing a nut part into two nuts, sensing a reaction force in the feed shaft of both the nuts, and placing relative revolutional quantity of both the nuts under the negative control. CONSTITUTION:When a reaction force is produced between both nuts 1 and 2 during revolution of the ball screw shaft 4 due to lead error thereof, the intensity of the reaction force is sensed by a reaction force sensor 23. When the detecting signal of the reaction force sensor is sent to a main controller 24, the main controller drives a fine-revolution mechanism 15 via a fine- revolution mechanism driver 21, whereby a little varying relative revolutional quantities of both nuts. Variation rate of revolutional torque of the ball screw shaft is thereby moderated so that stable feeding operation having high precision can be attained.

摘要： PURPOSE:To prevent a tap positively automatically from breakage while providing high efficiency working by using a relatively simple constitution for measuring and comparing with a detector light rays passing through a light transmitting window formed on the periphery of a rotary disk. CONSTITUTION:A torque detecting device for a tapping machine comprises rotary disks 12a, 12b and 13a, 13b. The disks 12a, 12b are mounted on the drive side sleeve 7 and the disks 13a, 13b on the driven side of an elastic member 26 respectively so that a torsion amount of a member 26 in working can be measured by comparing with the phase of signal of a detector 13 for detecting light ray passing through light transmitting windows in both disks. When the torsion amount exceeds torque within the allowable extent of a tap 10, the rotation of the tap 10 is once stopped and then reversed so that the tap 10 is operatively withdrawn. Thus, the tap 10 can be prevented from breakage automatically to provide high efficiency and accuracy tapping.

摘要： PURPOSE:To easily foresee break of a tool by detecting elastic waves including supersonic vibration from a torque limiter and detecting a condition before the break by the captioned device which performs in-process detection of an abnormal condition such as damage, break and the like of a cutting tool. CONSTITUTION:When a drill 1 is overloaded during cutting due to plugging of chips or the like and there is a fear of break of the drill 1, a torque limiter 3 repeats joining and disjoining movements and produces elastic waves including a high level of supersonic waves. The elastic waves pass through a tooling 4, bearing 7 and are transmitted to a main shaft head 6, and then detected by a detection part 12. However, a noise of the elastic waves detected by the detection part 12, after being excluded by means of a bypass filter 13, is amplified by means of an amplifier 14 and demodulated by a detector 15. This output is compared with a set value by means of an amplitude selector 16 and in case it exceeds the set value, a signal generator 17 gives an alarm.
