A machine tool includes a cutting unit and multiple quick-release elements. The cutting unit includes a handle including two lateral facets, an upper facet, multiple bores made in the upper facet, and multiple cutouts made in at least one of the lateral facets. Each of the cutouts is in communication with a corresponding one of the bores. Each of the quick-release elements includes a cam including an operative portion located further from a rotational axis than an idle portion. Each of the cams is inserted in a corresponding one of the bores. The idle portion of each of the cams is located in the corresponding bore when each of the cams is at a first angle. The operative portion of each of the cams extends from the corresponding bore through the corresponding cutout when each of the cams is at a second angle.

The invention describes a rotary cutting tool, in particular a drill, which comprises a first cutting tool part having at least one cutting edge and a second cutting tool part which comprises a cutting tool shank. The first cutting tool part and the second cutting tool part are releasably connected to one another via a coupling mechanism which comprises a coupling cam that is mounted on one of the two cutting tool parts such that it can rotate about an axis of rotation and, in a coupling position, abuts an engagement surface on the other cutting tool part. The invention also presents a cutting tool part, in particular a cutting tool base, and a further cutting tool part, in particular a cutting tip.

A rotary cutting tool includes a tool holder. The tool holder has holder body and an adjustment sleeve circumferentially disposed thereabout. The adjustment sleeve has an at least one sleeve adjustment groove which decreases in distance from a sleeve central axis in a rotational sleeve direction. The tool holder further has a plurality of insert cartridges, each having an insert pocket and at least one cartridge pin. At least one pin is located in a respective sleeve adjustment groove. The tool holder is adjustable between inner and outer adjusted positions by rotating the adjustment sleeve in the rotational sleeve direction. In the outer adjusted position, the insert cartridges are displaced in an outwards adjusted direction so that the insert pockets are radially outwards compared to the inner adjustment position.

The apparatus and method described herein allows for the automated replacement of end effectors on a robot without requiring external power source such as electricity or compressed air. The programmed robot motion provides the mechanism for tool changing. This simplified approach provides a simpler, less expensive solution to systems currently provided. The robot motion provides the mechanism and all the power needed to enable the tool changing.

A toolholder assembly includes a toolholder having a rearwardly facing toolholder shank, a base member having a bore configured for receiving the toolholder shank, a lock rod with an axial forward and an axial rearward end, at least one locking member in communication with the axial forward end of the lock rod, and a flexible canister configured for receipt in the bore of the base member. The flexible canister includes at least one flexible feature that reduces a stiffness (i.e., increases flexibility) of the flexible canister. In one aspect, the flexible feature is a slot proximate a locking passageway of the canister.

The invention relates to a drill hold assembly and a jig including the same. The drill hold assembly includes an engaging means which is selectively moveable between a released position to allow sliding movement of the drill bit with respect thereto and an engaged position in which the drill bit is held in a fixed position or within a predefined range of movement with respect to the engaging block to thereby maintain the drill bit in location with the drill hold assembly. The jig apparatus can be used with a powered drill to rotate the drill bit to provide a driving force to the drill bit and the jig is attached to a support surface and a workpiece is positioned between first and second jaws of the jig and the drill bit is advanced along a guide and introduced into the workpiece to form a hole therein at a predefined angle. The drill bit can then be removed from the hole and the drill bit is held by the drill hold assembly to retain the drill bit in a fixed position with respect to the jig to thereby allow relative movement of the jig apparatus and workpiece whilst the drill bit is retained in position with the jig apparatus.

The chuck with locking device has a ratchet mechanism comprising a toothed ring with engagement teeth fixed to one of an outer casing and a base body. A ratchet pawl is coupled to the toothed ring when a locking control sleeve is in a locking position and the locking pawl is separated from the tooth ring when the locking control sleeve is in a release position. A release elastic element is arranged under compression between the outer casing and a locking ring. The locking ring is fixed inside a locking control sleeve. A cam groove is formed in the locking ring. A pin is inserted in the cam groove and in a hole formed in the base body. The locking control sleeve moves the locking ring between the locking and unlocking positions.

A robotic tool changer includes a locking mechanism that enhances safety. More particularly, the locking mechanism is an over center locking mechanism that maintains a constant lock force on a tool. The lock force exerted on the tool by the locking mechanism remains substantially constant, even after a motor providing power to the robotic tool changer is removed, and after the robotic tool changer experiences mechanical wear.

A cutting tool includes a tool holding system having a clamping portion. The clamping portion includes an integrally formed one-piece inner coupling member that at least partially forms a clamping sleeve portion having a clamping bore for clampingly receiving a cutting insert. The clamping portion also includes an integrally formed one-piece outer coupling member that is circumferentially disposed about at least a portion of the inner coupling member. The tool holding system also has a mounting portion that is connected to one of the inner and outer coupling members. The inner and outer coupling members are captively and non-releasably engaged with each other via inter-engaged first and second engagement surfaces that are slidingly displaceable with respect to each other.
