    摘要: A toolholder for holding a cutting tool such as a tap in the spindle of a machine tool includes a torque-limiting clutch to prevent excessive load being applied to the cutting tool. The clutch comprises at least one ball located in sockets in the driving and driven members but there is an arrangement, whereby at a predetermined critical torque, the ball moves axially out of engagement with one of the driving and driven members to disconnect the drive, and a deflecting device engages with the ball and moves it to a position where it does not encounter the socket from which it has been released or any similar sockets. This prevents wear on the clutch.The toolholder also comprises a conduit system for cutting fluid being fed into a bore in the cutting tool. The conduit extends through a telescopic part of the toolholder and includes a flexible part deviating from a straight linear form, so that it can extend by tending to straighten, in order to accommodate telescopic extension of the toolholder.

    摘要: A releasable detent joint or coupling between telescoping cylindrical parts such as a receptacle and a tool holder held therein. The inner member is held by ball detents and a holding ring. The ring is expandable to allow release of the ball detents and separation of the parts in response to a predetermined applied torque to provide a safety release. In a simplified form of the invention, the holding ring is not expandable but release is effected merely by angular movement of the ring to a release position of the ball detents.

    摘要: The holder has a shank to be driven by a machine spindle, a sleeve axially slidable on the shank and rotatable thereby, and an adapter removably connected to the sleeve for rotation thereby. The adapter carries a removable tool, and is releasably coupled to the sleeve by a spring-loaded torque ring, which is axially slidable on the sleeve and holds a plurality of ball couplers resiliently in driving engagement with recesses in the adapter. When a predetermined torque is exceeded the balls are forced out of the recesses to interrupt the drive to the adapter, and also to force the torque ring upwardly to inoperative or released position. The sleeve is held in released position by a ball coupling which is engaged in stepped angularly and longitudinally spaced recesses in the sleeve.

    摘要: A tapping unit (1) includes a protection device (12) for permitting an axial retraction movement of a master screw (4) towards the interior of a casing (2) from a reference position into a first proximal backward position with a first defined penetration stroke during which a first elastic return device (13) constantly returns the master screw (4) to its reference position. The protection device (12) furthermore permits an additional axial retraction movement of the master screw (4) towards the interior of the casing (2) from the proximal backward position into a second proximal backward position with a defined penetration stroke during which the master screw (4) is no longer returned towards the exterior of the casing (2).
