    • The invention relates to a collet device, in particular for snap closure attachments for gaseous and/or liquid media which comprises a clamping plunger (4) and a plurality of collets (3) each with a connection end (3a) and a bearing end (3b). The bearing ends (3b) of the collets (3) are detachably suspended on the clamping plunger (4) and said collets can be displaced axially with the clamping plunger (4) using an actuating member. For simple and rapid replacement and assembly of the collets the invention proposes that the collet arrangement (3, 4) is linked to a fixing member (5; 5') movable in relation to the collet arrangement (3, 4) in order to lock the bearing ends (3b) positively.

    • Die Erfindung betrifft einen Spanndorn für Werkzeugmaschinen mit einer Mehrzahl von radial ausgerichteten Spannkörpern (14), die jeweils mit einer ebenen Fläche (64) versehen sind und sich mit dieser Fläche (64) auf einer zugehörigen Stützfläche (62) eines im Querschnitt polygonalen Spannkegels (104) abstützen, gegenüber welchem die Spannkörper (14) zur Erzeugung einer radialen Spannbewegung in axialer Richtung durch einen Zugkörper (156) verschiebbar sind, wobei die Spannkörper (14) jeweils mit einem radial ausgerichteten Vorsprung (142) zur formschlüssigen Mitnahme bei der Axialbewegung ausgebildet sind. Um einen Rundlauf mit einer Genauigkeit von weniger als 10⁻² mm einzuhalten sind die Spannkörper (14) in radialen, zur Vorderseite offenen Aufnahmen (92) eines Spannkopfes (12) angeordnet, der mit einer ringförmigen Nut (140) zur Aufnahme der Vorsprünge (142) der Spannkörper (14) versehen und mit dem Zugkörper (156) durch eine schnell lösbare Verbindung (Bajonettverschluß) verbindbar ist. Der Spannkopf (12) ist in seiner Gebrauchsstellung durch eine entriegelbare Verdrehsicherung gegen Verdrehung gehalten.
    • 本发明涉及一种用于机床的膨胀心轴,其具有多个径向取向的夹紧体(14),每个夹紧体均设有平面(64)并且在相关联的支撑表面(62)上由该表面(64)支撑, 夹紧锥体(104)的横截面为多边形并且相对于夹紧体(14)可以通过用于产生径向夹紧运动的张力体(156)在轴向方向上移位,夹紧体(14) ),每个都形成有径向定向的突起(142),用于在轴向移动期间进行正向锁定驱动。 为了以小于10 -2 mm的精度保持同心度,夹紧体(14)被布置在提供的夹紧头(12)的朝向前侧的径向插座(92)中 具有用于容纳夹紧体(14)的突起(142)的环形槽(14),并且可以通过快速释放连接(卡口卡扣)连接到张力体156。 夹紧头(12)通过可解锁的防旋转锁定装置在其使用位置上抵抗旋转。 ... ...

    • The invention provides an expanding mandrel comprising a shaft (1) having a conical forward end (10), an expanding sleeve (5) constituted by a ring provided with longitudinal slits designed to slide over said conical forward end (10), the inner wall of said sleeve (5) itself also having the shape of a cone the apex angle of which is equal to that of the conical forward end (10), and a tie member (2) designed to be connected to a rod that can be caused to slide along the axis of the machine spindle to control the gripping or the release of a workpiece. According to the invention, the sleeve (5) is connected to said tie member (2) via a control ring (3) integral with the tie member (2), and the mandrel comprises a removable quick mounting means enabling the sleeve (5) to be secured to said control ring (3).

    • An expanding collet assembly comprises an arbor having a flange portion for securing to a machine tool spindle and a shaft portion extending from the flange portion. The shaft portion includes a first conical surface disposed at its free end and a second conical surface disposed adjacent the flange portion. Conical surfaces are parallel to each other and disposed radially inwardly in the direction away from the flange portion. An expanding collet having alternately disposed slots to form a plurality of fingers extend inwardly from opposite collet ends and have inner conical surfaces at the collet ends that cooperate with the first and second conical surfaces. The expanding collet is axially slidably disposed around the shaft portion between a relaxed position when the collet is disposed away from the flange portion and an expanded position when disposed toward the flange portion. A draw plug with a flanged head in engagement with one end of the collet is disposed axially through the arbor in an opening in the shaft portion. A draw bar adapter is disposed within a recess in the arbor and secures one end of the draw plug, the adapter being secured to a draw bar for axially actuating the draw plug, thereby actuating the collet. An annular work locating stop is secured to the flange portion and overlies at least a portion of the collet, the stop having an annular free edge for abutting against a workpiece. Another embodiment of the expanding collet assembly for smaller workpieces is also disclosed.
    • 一种膨胀的夹头组件包括具有用于固定到机床主轴的凸缘部分和从凸缘部分延伸的轴部分的心轴。 轴部包括设置在其自由端的第一锥形表面和邻近凸缘部分设置的第二锥形表面。 锥形表面彼此平行并且沿远离凸缘部分的方向径向向内设置。 具有交替设置的狭槽以形成多个指状物的扩张夹头从相对的夹头端向内延伸,并且在夹头端处具有与第一和第二锥形表面协作的内锥形表面。 当夹头远离凸缘部分放置在松弛位置之间时,膨胀的夹头可轴向地可滑动地设置在轴部分上,并且当朝向凸缘部分设置时,该扩张夹头可沿轴向可滑动地设置。 具有与夹头的一端接合的凸缘头的牵引塞在轴部的开口中轴向地设置穿过心轴。 拉杆适配器设置在心轴中的凹部内并且固定拉拔塞的一端,适配器被固定到拉杆上以用于轴向地致动拉拔塞,从而致动夹头。 环形工件定位止动件固定到凸缘部分并且覆盖在夹头的至少一部分上,止动件具有用于邻接工件的环形自由边缘。 还公开了用于较小工件的膨胀夹头组件的另一实施例。
