摘要： A toolholder device for a machine tool comprises a holder body driven by a machine tool drive spindle, and a toolholder supported on the holder body so as to be circumferentially and axially displaceable. The holder body and the toolholder are provided with displacement detection elements which are arranged circumferentially in interdigitating relation. A support shaft extends from either member of the holder body and the toolholder toward the other member. The outer surface of the support shaft and the inner surface of a support hole of the other member to be fitted over the support shaft are formed with helical guide grooves which are opposite to each other and slopingly extends with respect to the rotational axis of the toolholder device. Balls are interposed between the opposite guide grooves to form a displacement translation mechanism which converts a rearward axial displacement of a tool and the toolholder due to overload axial thrust into a circumferential relative displacement between the adjacent detection elements. The relative displacement of the detection elements is detected by a detection unit which issues a warning signal. A compression spring in the device resists the axial displacement of the toolholder unless the axial thrust exceeds a predetermined value.

摘要： A toolholder assembly is divided into a drive toolholder coupled to the drive spindle of a machine tool, and a driven toolholder carrying a cutting tool such as a drill. The driven toolholder is coupled end to end to a drive toolholder so as to be rotatable relative to the same through a preassigned angle about the toolholder axis. A coiled torsion spring acts between the drive and the driven toolholders for torque transmission from the former to the latter. The drive and the driven toolholders have interdigitating teeth with clearances therebetween. A phase detector such as a proximity switch detects a relative phase displacement that will occur between the interdigitating teeth against the force of the torsion spring upon development of abnormal torque load on the cutting tool. Preferably, the interdigitating teeth have bevels in sliding engagement with each other for causing a relative phase displacement between the teeth upon axial displacement of the driven toolholder toward the drive toolholder, so that not only abnormal torque load but also abnormal thrust load on the cutting tool is detectable by the phase detector.

摘要： An apparatus for producing special yarn made of a fiber strand in which a number of fibers are randomly arranged along the lengthwise direction thereof, in which special yarn at least one of the yarn structural parameters, e.g., yarn count number or number of twist, changes along the lengthwise direction of the yarn.A pattern of change of the parameters of the yarn structure with respect to the length of the special yarn to be produced is stored in a central processing device, while a spun length of the special yarn is measured by a sensor. The yarn structural parameters are changed to correspond to the pattern set to the central processing device and the special yarn is produced by the yarn forming device using another central processing device of the spinning frame.This apparatus can be used for a ring spinning frame, an open end spinning frame, a fasciated yarn spinning frame, and the like.
