Devices are described relating to the retaining of surgical tools within the chuck of a reciprocating surgical instrument, such as a reciprocating saw. A securing chuck is disclosed for securing a surgical tool to a reciprocating surgical instrument that comprises a shaft and a securing member. The shaft defines an axis and has a cylindrical bore extending along the axis. The bore is shaped to receive a substantially rounded tool shank. A pair of transverse slots extends into the shaft along a plane passing through the axis for receiving a substantially flattened tool shank. The transverse slots intersect with the cylindrical bore. The securing member is carried by the shaft and is radially movable relative to the bore both inwardly and outwardly to secure the surgical tool in the chuck.

A manual robotic tool changer provides a compact, lightweight means to manually selectively couple a robotic tool, such as a surgical tool, to a robot arm. The tool changer includes numerous safety features to prevent inadvertent decoupling of the robotic tool. These include a dual-button handle locking mechanism operative to lock the tool changer closed in the fully coupled position, and requiring simultaneous actuation of both of two latch buttons to unlock; a one-way clutch mechanism that prevents rotation of the coupling mechanism towards the decoupled position, unless the handle is actuated to unlock the tool changer; and a spring biasing the tool changer to an at least partially coupled state when no force is applied to the handle, thus requiring a positive force against the spring, moving the handle to a fully open position, to insert or remove a robotic tool.

A tool with a replaceable tip includes a tool body including a tip holding portion, a tool tip having a shank portion adapted to be disposed proximate the tip holding portion comprising a wall defining an axial opening, the wall having at least one radial opening, at least one locking element being disposed in the radial opening, and, as a clamping ring is turned about the longitudinal axis of the tool body, a locking element contacting surface of the clamping ring contacts the locking element and urges it through the radial opening and into the recess in the tool tip. A method of retaining a tool tip is also disclosed.

In a robotic tool coupler, a rotating cam member having a plurality of surfaces formed therein urges a plurality of ball members in one tool coupling unit radially to contact an angled surface in the other tool coupling unit. Further rotation of the cam member exerts a radial force through the ball members onto the angled surface. A component of that force is directed by the angled surface toward the opposite tool coupling unit, locking the two units together. The cam member may include a failsafe surface and/or a failsafe lobe to maintain the two units locked together in the event of a loss of power to positively actuate the cam member.

Embodiments are disclosed for a tool-less clamping apparatus for a reciprocating tool having a reciprocating spindle having a center axis and at least one radially oriented aperture and a receiving slot at its forward end for receiving a tool accessory, the apparatus having an unclamped position and a clamped position, and comprising a hollow generally cylindrical sleeve secured to the spindle, a hollow generally cylindrical collar configured to fit on the sleeve and being rotatable relative to the spindle and the sleeve, the collar having an inner cam surface that increases in radius from the axis through a first predetermined circumferential arc in a first direction, a spring operatively connected to provide a biasing force to the collar toward its clamped position, and a detent pin positioned in the spindle aperture and configured to engage a hole in the tool accessory and thereby firmly hold the tool accessory in the apparatus when urged into contact with the tool accessory.

An auto hammer having a housing, a grip portion and a striking device. The striking device includes a striking rod for striking a nail or other element using a straight reciprocating motion. The striking device has an associated clamping mechanism for clamping the nail or other element. The clamping mechanism has a driving portion, a first clamping portion, and a second clamping portion. The first and second clamping portions are moved between a closed position and an opened position. In the closed position, the element is held between the first and second clamping portions. A first slot and a second slot are arranged on the first and second clamping portions respectively. The driving portion is arranged in both the first and second slots and moves along the first and second slots.

An arrangement for holding a tool fitting for driven tools has a spindle with a forward directed surface and a bore which intersects the forward directed surface and which, starting from the forward directed surface, extends rearwardly in order to receive a shaft of the tool fitting as well as with a device for locking the tool fitting with the spindle. Inner and an outer locking elements of the arrangement are engage a bayonet coupling and a manacle ring is engaged with the outside of the spindle. The manacle ring also acts directly on the outer locking element and the outer locking element is formed by a projecting element which engages in a blind stop groove in the inner locking element. The stop groove extends first axially and then subsequently radially in a circumferential surface of the tool fitting starting from an end face of the tool fitting.

The present invention generally provides a saw blade clamping assembly. The assembly has a main body, a clamping device, a rotating sleeve and a biasing device. The main body has a receiving slot for receiving a fixing end of a saw blade and an oblique and elongate hole communicating with the receiving slot. The clamping device has at least one clamping member passing through the oblique and elongate hole of the main body. The rotating sleeve encloses the main body and the clamping device. The biasing device is biased between the main body and the rotating sleeve.

The invention relates to a hand jig saw having a chucking device for a tool that can be moved back and forth, particularly a jig saw blade (15), the device having a centering piece (18) firmly connected to a drivable rod (13), the centering piece having an axial insertion slot (26) for a shank of the tool and at least one clamping body (19), which can be displaced in a transverse channel (27) extending transversely to the insertion slot (26) and immerses into the insertion slot (26), for clamping the shank (153). For displacement, the clamping body interacts with a chucking cam (28) configured on a chucking sleeve (20), which can be rotated relative to the centering piece (18), is disposed concentrically thereto and spring-loaded in the direction of rotation. In order to achieve a symmetrical chucking position of the tool in the chucking device and improved handling during replacement of the tool, two clamping bodies (19) arc disposed in two mutually aligned transverse channels (28) ending in the insertion slot (26) and displaceable in relation to each other, the chucking sleeve (20) is provided with two diametrically opposed chucking cams (28) arranged point-symmetrically relative to the axis of the chucking sleeve (20) for displacing the clamping bodies, and in the insertion slot (26) an axially displaceable spacer (22) that is spring-loaded in the extension direction of the jig saw blade (15) out of the centering piece (18) is held, on the longitudinal sides of which facing away from each other the clamping bodies (19) are non-positively applied by the chucking cams (28).
