In order to achieve a compact spindle drive which is also lightweight and consisting of few components, and where the drive motor (8) is mounted in a stationary manner in relation to the spindle drive, the spindle drive according to the invention is configured with two sets of bevel gears comprising a first larger pair of gears (11, 13) and a second smaller pair of gears (12, 14). The spindles (15, 17) can hereby be mounted in star formation in the housing and alternately enter into engagement with the first gear (11) and the second gear (12), and thus alternately rotate the one way and the other way. At the same time, all of the spindles (15, 17) are suspended in the same plane, whereby a very uniform machining operation is achieved. Finally, the housing can be provided with a turning motor (21), which via a pinion (2, 19) can revolve the housing (1) at the same time that the spindles rotate.

Le moteur (34) peut assurer le nombrage du plateau (9) si le pignon (30) est en prise avec le disque (21) et si l'arbre (19) est déplacé vers la gauche afin de dégager la couronne mobile (24) de la couronne fixe (23). Dans ce cas, le porte-outil (15) est dégagé de l'élément d'accouplement (43). Lorsque la tourelle est bloquée, l'entraînement du porte-outil tournant (15) par l'arbre de transmission (39,41) se fait par l'intermédiaire du pignon (35) de la couronne (36) et du pignon (38). Tout porte- outil tournant placé dans n'importe laquelle des alésages (10) peut être amené par nombrage de la tourelle (9) dans l'emplacement d'usinage et est alors accouplé à l'élément (43).
摘要:
An automatic tool exchange device for a machine tool has a spindle head (4) rotatably bearing a spindle (2) and a magazine (40) having a plurality of tools. A pair of gear wheels (46, 48) are provided for the spindle and the magazine respectively, to index them by engaging the two gear wheels (46, 48) so that they are driven by a spindle motor (6) when exchanging tools and disengaging them when machining with a machine tool. The engagement and disengagement of the gears is performed by the relative axial motions of a cooperation slider (30) bearing the head (4) and the magazine (40).

A tool (10) including a drive shaft (36) having an axis of rotation, and a plurality of bit holders (28,30) interchangeable with one another at a position of use. The bit holders (28,30) being mounted on a turret (26) which is rotatable around an axis (k) set at an angle to the axis of rotation of the drive shaft (36). The drive shaft (36) being in drive connection with a respective bit holder (28,30) at the position of use, wherein the tool (10) includes means (20x) for engaging a clutch (46) which activates a drive train (44) to establish a drive connection between the drive shaft (36) and the turret (26) so that subsequent operation of the drive shaft (36) rotates the turret (26) to interchange the positions of the bit holders (28,30) at the position of use, and wherein after the turret (26) has been rotated the clutch (46) is disengaged to deactivate the drive train (44) to prevent any further rotation of the turret (26).
摘要:
Die Erfindung betrifft ein Motorhandwerkzeug (1) zum Bohren/Schrauben, mit einem Gehäuse (2) mit darin vorgesehenem Motorantrieb (3) und angeschlossener Antriebswelle (4) und mit einem Revolverkopf (7) mit antreibbaren Kupplungsköpfen (8a,8b), die in eine angetriebene Position und in eine Parkposition verschwenkbar sind, wobei die Antriebswelle (4) über zumindest ein Zwischenelement (9) mit einem ersten Kupplungsteil (10) im Revolverkopf verbunden ist und jedem Kupplungskopf jeweils ein zweites Kupplungsteil (11) zugeordnet ist, welches sich nur in der aktiven Position dieses Kupplungskopfes in Eingriff mit dem ersten Kupplungsteil (10) befindet. Für ein Verdrehen des Revolverkopfes (7) ohne aufwändiges Entkoppeln der Kraftübertragung zum Revolverkopf soll als ein Zwischenelement (9) eine im Bereich der Drehlagerung des Revolverkopfes in den Revolverkopf hineingehende Zwischenantriebswelle vorgesehen sein, deren im Gehäuse befindliches Ende von der Antriebswelle (4) angetrieben wird und deren im Revolverkopf befindliches Ende mit einem Kegelrad als ersten Kupplungsteil (10) verbunden, insbesondere versehen ist, dessen Drehachse (B) nicht mit der Drehachse (A) der Drehlagerung des Revolverkopfes fluchtet.

Le centre comprend un convoyeur, un chariot motorisé muni d'une pince pour déplacer un profilé (2) sur le convoyeur vers le bâti fixe (7) d'un poste d'usinage suivant un axe numérique et un étau (11). Selon l'invention, le poste d'usinage comporte uniquement: deux éléments mobiles en translations croisées (16, 21), le premier (16) étant mobile par rapport au bâti fixe (7) et le deuxième (21) par rapport au premier (16), ce deuxième élément mobile (21), portant une tête orientable d'usinage (25) équipée d'au moins un outil (5). Par ailleurs, l'actionneur (22) qui commande en déplacement chaque élément mobile est polyvalent et est piloté par la commande numérique de façon sélective dans le cadre de son programme général pour exécuter notamment des consignes exclusives de positionnement, des consignes exclusives d'avance d'usinage ou des consignescombinées.
摘要:
To provide a tool post for a machine tool that can smoothly detach an engaging member in a side of a supporting member and an engaging member in a side of tool, the engaging members engaging in accordance with the movement of the tool. A first driving force transmission part (51) is disposed between an attachment part turning transmission shaft (90) located in a side of a tool post body (11) and a tool attachment part (15) located in a side of a first turning driving force transmission shaft (81). The first driving force transmission part (51) transmits rotary driving force from a side of the attachment part turning transmission shaft (90) to the side of the first turning driving force transmission shaft (81). The first driving force transmission part (51) includes a groove (97a), a tenon shaped protrusion (92), and protrusions (93a, 93b). The groove (97a) is formed on a tip of a slide shaft (97) of the attachment part turning transmission shaft (90). The tenon shaped protrusion (92) is formed in the first turning driving force transmission shaft (81) and detachably engages with the groove (97a). The protrusions (93a, 93b) once releases an engaging posture by pressing the groove (97a) that is biased to the engaging posture in an disengaging state when the tool is in the middle of the movement to a predetermined position.
