A device for coupling and centering tools has a tubular portion with a coupling seat laterally delimited by a cylindrical centering surface, a first threaded hole with a first tightening dowel projecting into the coupling seat, a second threaded hole with a second tightening end projecting into the coupling seat, a third hole tangential to the centering surface and a locking pin removably lockable in the third hole in a position interfering with the coupling seat, and removable from the third hole to free the coupling seat.

Devices, systems and methods for holding devices, including tool holders and/or associated apparatus, that can be attached to various driving mechanisms. Various embodiments can include one or more canted, or slanted, coil springs that are capable of forming to various shapes by the application of a controlled force.

A ball bearing connector is provided, comprised of a setting tool further comprised of several steel balls which are biased either inwardly or outwardly by means of a biasing member. An easily interchangeable drill stop further comprised of an annular recession is position into or over the setting tool, and the balls located thereon fit in the annular recession to provide a releasable snap-fit connection between the drill stop and the setting tool.

A tool connector generally includes a tool receiving portion configured for reciprocating between first and second work tool seating positions, wherein the tool receiving portion is normally biased to the first work tool seating position, and actuatable to the second work tool seating position. The tool connector further includes a magnetic mechanism in the tool receiving portion for providing magnetic force to engage a work tool in either of the first and second work tool seating positions, and a locking mechanism for lockingly engaging a work tool in the second work tool seating position.

A surgical component connecting device, kit, and method are disclosed. The surgical component connective device includes an outer body, a body element, and a support element. The support element is slidably mounted relative to the body element. Two or more surgical component engaging elements provided towards the distal end of the body element, and at least one of the surgical component engaging elements is operably connected to the support element. The two or more surgical component engaging elements have a first state and a second state. The separation of the two or more surgical component engaging elements is greater in the second state than in the first state.

A manually actuated robotic tool changer comprises master and tool units, each adapted to be connected to a different one of a robotic arm and a robotic tool. The tool changer includes a plurality of rolling members retained in one of the units and a piston mounted in one of the units and moveable in an axial direction. The piston includes a multi-faceted cam surface including an initial contact surface, a locking surface, and a failsafe surface interposed between the initial contact surface and the locking surface. When the piston is in a locked position in the tool changer, the cam surface is operative to contact the rolling members in one of the units and to urge each rolling member against a surface of the other unit to couple the master and tool units together.

The invention relates to a device for detachably securing modules (1), such as tool holders, to a third component (3), such as a rotatable tool disk for a machine tool, including a controllable securing device (51, 53), by which the respective module (1) can be re-secured in a detachable manner in a locked position on the third component (3) by individual securing parts (15). A release device (76, 77) at least partially helps to release the securing device (51, 53) in a release position, such that the release device (76, 77) at least at the beginning of releasing, exerts pressure on the securing device (51, 53) for releasing the individual securing parts (15).

In a handheld machine tool having a tool holding fixture, which has a multi-faced inner receptacle and a multi-faced outer receptacle, the multi-faced inner receptacle being configured for the connection to a first tool insert, which is able to be locked in the multi-faced inner receptacle using a locking device assigned to the tool holding fixture, and the multi-faced outer receptacle being configured for the connection to a second tool insert, which has an inner multi-faced coupling that is able to be slid onto the multi-faced outer receptacle. The locking device has an actuating element, which is rotatable about a longitudinal axis of the tool holding fixture for unlocking the first tool insert from a specified locking position into a specified unlocking position.

A tool, in particular for use as a surgical drill, has a main tool body which, in order to be connected to a tool attachment unit, has a fixing unit which is provided to be at least partly unusable after the main tool body has been detached from the tool attachment unit. The fixing unit has at least one form-fit element, which is provided to accept axial tensile forces in order to axially secure the main tool body to the tool attachment unit. The fixing unit has an assembly direction and a deflection element which points in the assembly direction, and which is provided for movably attaching the form-fit element to the main tool body. It is proposed that the form-fit element and the deflection element have different directions of extension.
