    摘要: A bit retention device includes a shaft having a sidewall defining a hexagonal cavity extending from a first end thereof and a ball groove extending through the sidewall and communicating with the hexagonal cavity. A ball is disposed in the ball groove and a ball spring engages the ball and biases the ball toward the first end. An actuator sleeve surrounding the shaft includes an internal ramp engaging the ball. The internal ramp includes a shallow ramp portion having a first angle of inclination with respect to a center axis and a steep ramp portion having a second angle of inclination with respect to said center axis of said shaft that is greater than the first angle of inclination. A spring biased plunger assembly is disposed in the bore for biasing a bit received in the bore in a direction toward the insertion end.

    摘要: The invention provides a ball-lock insert assembly adapted to be mounted axially in a mount opening formed in a holder plate having a desired thickness. The ball-lock insert assembly comprises an insert body having an axis and an elongated interior recess (17) extending at an angle relative to this axis. The elongated interior recess (17) is configured to house a resiliently-biased engagement member (27). The invention also provides retainer assemblies that include ball-lock assemblies, as well as methods of producing retainer assemblies, which methods include providing ball-lock assemblies.

    摘要: The invention relates to a surgical instrument with a tubular shaft. The instrument comprises a shaft (12), a working rod (16) that is displaceably mounted in said shaft (12), a handle part (18) for operating the working rod (16), and connecting means which detachably connect the handle part (18) and the shaft (12) to each other. The shaft (12) can be fixed in an inner sleeve (30) of the handle part (18) in an axial direction by means of an interlocking body (42) which is inserted into a recess (44) of the shaft (12) and which is radially displaceable in the inner sleeve (30). The radial outward movement of the interlocking body (42) is limited by a stop element (68) which can also be moved into a position in which it enables the interlocking body (42) to move radially outwards. Fixing means (80, 90) are provided and allow the stop element (68) to be fixed in an enabling position. Said fixing means (80, 90) can be acted upon by the shaft (12) in such a way that this fixed state can be released through the displacement of the shaft (12) in the inner sleeve (30). The aim of the invention is to configure an instrument of this type in such a way as to simplify its structure. To this end, the fixing means comprise a fixing element (80) that is displaceably guided in the handle part (18), outside of the inner sleeve (30).

    摘要: A piercing saw machine (10) has a device (20) for clamping the saw blade (22) at the lower end of a reciprocating rod (18). A clamping sleeve (40) can axially slide and rotate on the reciprocating rod (18) and is provided at its free lower end with an inwardly projecting continuous collar (46) with a passage (48) and a radial slit (47). In the clamping position, the collar (46) is axially supported against heels (49, 50) of the saw blade (22) and thus pushes the saw blade clamping end (25) against the lower front face of the reciprocating rod (18) or against an elastic separator (22). In order to obtain a piercing saw machine (10) that is easier and safer to use, locking means are provided for retaining the clamping sleeve (40) in relation to the reciprocating rod (18) in the saw blade (22) releasing position. When the saw blade (22) is set in and moved in its clamped position, the locking means release again the clamping sleeve (40).

    摘要: Dispositif de retenue de poinçon (20) amélioré dans lequel une plaque d'appui (24) s'étend sur une surface relativement grande pour dissiper la force émanant d'un poinçon (64). Un corps de retenue (22) et la plaque d'appui sont reliés l'un à l'autre de façon permanente et comportent des passages (38, 40, 42, 44 et 46) qui sont finalement meulés après avoir été fixés à demeure. Ce dispositif permet d'avoir des passages dans la plaque d'appui et dans le corps de retenue bien alignés durant la constitution du dispositif de retenue de poinçon. Comme la plaque d'appui dissipe la force sur une surface relativement grande, le dispositif de retenue de poinçon peut être utilisé dans des conditions plus sévères que les dispositifs de retenue de poinçon de l'art antérieur. Un passage de ressort (56) est fermé par un élément étanche (79) inséré dans la plaque d'appui, ce qui permet l'utilisation de ressorts standard (82).

    摘要: Es wird ein Schnellwechselsystem für eine Werkzeugaufnahme (14) angegeben, mit einer maschinenseitigen Aufnahme (12), die einen hohlzylindrischen Fortsatz (28) aufweist, auf dem eine Schalthülse (18) verschiebbar gehalten ist, wobei im Fortsatz erste Kugeln und axial und winkelmäßig dazu versetzt zweite Kugeln (44) gehalten sind, wobei die Werkzeugaufnahme (14) auf der der Aufnahme (12) zugewandten Seite einen zylindrischen Halteabschnitt (22) mit Längsnuten aufweist, die mit den ersten Kugeln zur drehfesten Festlegung der Werkzeugaufnahme (14) zusammenwirken, mit einer sternförmigen Stirnfläche (40) am Ende des zylindrischen Halteabschnitts (22) mit ersten Vertiefungen (52) zwischen jeweils benachbarten Spitzen der Stirnfläche (40) zur Aufnahme und Führung der ersten Kugeln in die Längsnuten beim Einschieben in den hohlzylindrischen Fortsatz (28) und mit zweiten Vertiefungen (46) am zylindrischen Halteabschnitt (22), die mit den zweiten Kugeln (44) zusammenwirken, um die Werkzeugaufnahme (14) in Axialrichtung zu fixieren, wobei an der Schalthülse (18) die zweiten Kugeln (44) zugeordnete Vertiefungen (26) vorgesehen sind, die ein radiales Ausweichen nach außen erlauben, wenn diese mit den zweiten Kugeln (44) ausgerichtet sind, und wobei die Spitzen der sternförmigen Stirnfläche (40) zur winkelmäßigen Ausrichtung der Werkzeugaufnahme (14) an den ersten Kugeln beim Einführen des Halteabschnitts in den hohlzylindrischen Fortsatz (28) ausgebildet sind.

    摘要: The specification describes a tool arrangement and chuck apparatus for quick change of a range of tools. In particular, a quick change chuck adapted to engage various diameter drill bits, tools and tool holders. The tools are rotatable in a chuck or adaptor and have at one end a centreing shaft portion having a constant diameter for mulitple tool end diarneters and shapes, a drive shoulder portion and a lock portion in any order. The chucks are described as haying a tool cenerting arrangement for accomodating the constant diameter centering shaft. The chucks are also described as having tool bit release mechanism operable to disengage the tool from a retention mechanism when a force is applied inwards of the body of the chuck by the user to allow the tool bit to be removed longitudinally from the chuck but also arrange to allow the tool bit to be inserted longitudinally into the chuck without requiring any other user operation.
