Abstract:
A tool bit stop (24) located on an inner surface (32) of a clamping jaw (16) of a drill chuck (10) The tool bit stop (24) is located a distance from a clamping jaw gripping surface (30) of the clamping jaw (16) The tool bit stop (24) is adapted to provide a surface to register an end (48) of a tool bit (44) in a consistent location relative to the jaw gripping surface (30) The tool bit stop (24) is shaped to allow advancement and retraction of the clamping jaws (16) without interference from the tool bit stop (24).
Abstract:
A chuck has a generally cylindrical body member having a nose section and a tail section. The tail section is configured to mate with the drive shaft so that the body rotates with the drive shaft. The nose section has an axial bore formed therein and a plurality of jaws is slidably positioned to engage a bit within the axial bore. Each of the jaws has a bit engaging jaw face formed thereon. One or more centering members are disposed adjacent to the jaws. The members are deformable from a first position where the members define a through passage configured to accept a bit, which has a drive shaft diameter less than a predefined diameter. The members are further configured to be deformable to a second position upon the insertion of a bit, which has a diameter greater than the predefined diameter, into the axial bore.
Abstract:
Die Erfindung betrifft ein Futter (2) zur Halterung von jeweils mit einer radialen Druckfläche und einem Mitnahmeprofil (17) versehenen Befestigungselementen (1) für eine Reibschweissverbindung an einem Bauteil und zur Übertragung von auf ein Befestigungselement wirkenden Rotations- und Druckkräften. In dem Futter (2) ist zur Übertragung der Rotationskraft eine Ringaufnahme (9) vorgesehen, die das ein axiales Mehrkantprofil aufweisende, eingeführte Befestigungselement satt umfasst. Das Futter weist ein in der Ringaufnahme (9) rückziehbares Druckstück (18, 27) auf, das von der Ringaufnahme geführt und in der Ringaufnahme zur Zuführung eines Befestigungselementes durch eine seitliche Öffnung (12) an der Ringaufnahme bis hinter die Öffnung zurückziehbar und nach Einführung eines Befestigungselementes in eine Wartelage gegen die Druckfläche (19) des Befestigungselementes derart vorschiebbar ist, dass das Befestigungselement in der Reibschweissposition bei seiner Rotation gegen das Bauteil drückt, wobei in der Wartelage das in die Ringaufnahme eingeführte Befestigungselement von radial nach innen ragenden, rückziehbaren Stoppteilen (10, 11) in axialer Richtung gehalten wird.
Abstract:
The invention relates to a clamping chuck (1) for a tool (6) comprising a device (9) for supplying a cooling agent and/or lubricants to a feeding channel (7) of the tool maintained by the clamping chuck (1). The inventive clamping chuck (1) comprises a sleeve (13) for coupling a feed pipe (10) for supplying a cooling agent and/or lubricants, the sleeve (13) provided with a tubular element (14) and an adjusting screw (15) which is arranged thereafter in such a way that it is displaceable with respect to the clamping chuck (1) in the direction of the longitudinal axis thereof.
Abstract:
The invention concerns a chuck (1) with a shank (4) having an axially located cylindrical opening (41) designed to hold the fixation lug (5) of a tool (6). Mounted in a bore (10), which is also located axially, is an axially movable stop piece (11, 12, 13) with a rack-like tooth construction (14). An adjustment shaft is mounted in a bore (15) at right angles to the chuck axis, the shaft having a second tooth construction (17) which engages with the first (14) on the stop piece. This makes it possible to adjust the stop piece (11), the end (12) of which forms the stop for the fixation lug (5) of the tool (6), by adjusting the chuck directly. The time-consuming repeated removal and insertion of the chuck in a pre-setting device, necessary with prior art equipment, is eliminated.
Abstract:
Die Beschreibung zeigt ein Spannzangenfutter 303 zum Einspannen eines Werkzeugs zur spanenden Bearbeitung eines Werkstücks, umfassend: eine Ausnehmung zur Aufnahme einer Spannzange 301, wobei das Spannzangenfutter 303 eine Schneide 306 zur spanenden Bearbeitung des Werkstücks aufweist.
Abstract:
Ein einfach herstellbares Hydraulik-Dehnspannfutter (1) umfasst ein werkzeugseitiges Ende (3) sowie ein maschinenseitiges Ende (4). An dem maschinenseitigen Ende (4) ist ein Schaft (7) zum Einspannen des Dehnspannfutters (1) in einer Werkzeugmaschine angeordnet. An dem werkzeugseitigen Ende (3) ist eine von einer Druckkammer (22) umgebene Dehnbuchse (21) angeordnet, die zum Einspannen eines Werkzeugs unter Wirkung eines in der Druckkammer (22) aufgenommenen Druckmediums (F) radial verformbar ist. Das maschinenseitige Ende (4) ist hierbei durch einen den Schaft (7) tragenden Grundkörper (8) gebildet, an den werkzeugseitig eine die Druckkammer (22) außenseitig begrenzende Spannhülse (9) starr angefügt ist. Im Inneren der Spannhülse (9) ist eine sowohl von der Spannhülse (9) als auch von dem Grundkörper (8) separate Innenhülse (12) eingefügt, die die Dehnbuchse (21) beinhaltet und die Druckkammer (22) innenseitig begrenzt. Die Innenhülse (12) weist hierbei an ihrem werkzeugseitigen Ende (3) einen radial nach außen ragenden Ringkragen (14) auf, der mit der Spannhülse (9) überlappt.
Abstract:
A drill includes a chuck which has a body member including a bore to receive a tool. Jaw members frictionally engage the tool to retain the tool in the chuck. A member is associated with the jaw members and the body to move the jaw members between clamping and non-clamping position. A centering mechanism extends radially into the body member to center tool bits within the chuck while prohibiting the tool bit from contacting the bore wall.
Abstract:
The present invention refers to a key cutting machine for the 10 duplication of keys, in particular of so-called "laser-type" keys, comprising a mechanical machining unit (1) connected to an electronic control unit (2) that is provided with memory means for storing the coded data of the keys to be duplicated, in which said mechanical machining unit comprises, along with a tracer or key follower (15) for tracking the bit notch pattern of 15 the keys to be duplicated, a spindle (13) and a milling cutter (14) associated thereto, both said cutter and said spindle being adapted to be driven rotatably about the axis thereof, as well as a carriage (5) on which there is mounted a jaw (9), said carriage being movable on the base-plate (4) of the mechanical machining unit in a plane that is orthogonal to the 20 plane of the milling cutter and the key follower or tracer. Said milling cutter (14) is temporarily attached to the end portion of a stem (18) that is adapted to be inserted axially in said spindle (13) through the back-side end portion of the latter, so as to enable said milling cutter to be fastened to said end portion of the same spindle. The milling cutter 25 (14) is adapted to be brought into contact with a reference plane on the jaw (9) so as to directly and readily achieve a correct setting and adjustment of the milling cutter (14) itself in the operating position thereof.
Abstract:
A tool receiver or chuck (10) is provided which may receive a cutting tool (14) therewithin and non-rotatably retain the tool relative to a rotary driving device (12). The tool receiver (10) includes a plurality of blades (16) substantially encased within a conical surface. A biasing member (18) biases the blades toward (16) a narrow end of the conical surface such that the (16) blades are biased in a tool engaging or operative position. The tool receiver (10) preferably includes a retaining member (26), which retains the blades within the conical surface and biases the blades radially outwardly toward the conical surface. The tool (14) may be released by overcoming the biasing force of the biasing member by moving or sliding a retaining ring (26a) or by activating a lever (38) or the like, such that no accessory wrenches or tools are required to insert or release a cutting tool or bit.
