摘要:
Dispositif pour l'usinage d'une pièce métallique maintenue dans un dispostif de serrage, par des outils (WZ) utilisés en alternance pouvant être sortis d'un magasin d'outils (14) avec un contrôle automatique séquentiel des étapes de l'usinage. Ce dispositif comprend également un dispositif de changement de broche d'outil et un dispositif de changement d'outil constitué d'une pince (ZQ) déplaçable, rotative et pivotante dont les mâchoires (28, 29) peuvent être ajustées sur l'axe de prélèvement des outils et sur l'axe de la broche respectifs (Z). Le dispositif comprend en outre un contour (30) profilé de mâchoire symétrique pour loger les outils (WZ), comportant au moins deux grandeurs différentes de tige respectivement de cône, avec au moins trois sections (a, b, d) en forme d'arc de cercle, raccordées les unes aux autres, dont les rayons (ERa, ERb, ERd) sont adaptés aux différents diamètres d'au moins trois grandeurs de tige ou respectivement de cône et pour lequel la broche d'outil respective (10), qui se trouve dans la position de travail, est introduite dans un dispositif de montage d'où elle peut être extraite et remplacée par une broche d'outil (11) à disposition dans une position de réserve. Les trois sections (a, b, d) au moins, en forme d'arc de cercle, des mâchoires (28, 29) sont écartées (f) des arcs générateurs correspondants dont les centres de cercle (Ma, Mb, Md) sont situés sur un arc d'ouverture (KB) coupant l'axe d'amenée et d'évacuation (x). Le centre générateur (MKB) des arcs générateurs coïncident avec le centre (D) des mâchoires de pince (28, 29).
摘要:
Device for the machining of a workpiece in a clamping fixture by using tools (WZ) which can be taken in alternating sequence from a tool magazine with sequence control of the machining steps, with a tool spindle unit changing device (14) consisting of a movable, rotatable and pivotable clamp (ZQ), the jaws (28, 29) of which can be directed towards the tool extraction and spindle axes (Z), and a mirror-image jaw shape (30) to accept tools (WZ) with more than two different shank or taper sizes with at least three adjacent arc-shaped sections (a, b, d), the radii (ERa, ERb, ERd) of which match the different diameters of at least three shank or taper sizes, and in which the tool spindle unit (10) which is in the working position can be inserted into and removed from a holder and exchanged for a tool spindle unit (11) in a stand-by position. The at least three arc-shaped sections (a, b, d) of the jaws (28, 29) are at a distance (f) from the generatrix arcs with their centres of curvature (Ma, Mb, Md) on an arc aperture (KB) intersecting the insertion and removal axis (x), the generatrix centre (MKB) of which coincides with the centre of rotation (D) of the jaws (28, 29).
摘要:
The invention relates to a method and device for machining out of round contours by using a cone-shaped or truncated cone-shaped tool which is rotationally mounted on a spindle. The spindle is arranged at a certain angle in relation to the work piece axis on which the contoured work piece is mounted. During machining, the tool pivots around at least one first pivoting axis which deviates from the spindle axis. Alternatively, the work piece can be correspondingly moved, and the tool can remain oriented in the same position. The tool and the work piece can also undergo a corresponding movement since it is simply a matter of relative movement between the tool and the work piece. In addition, the invention relates to a device for carrying out said method.

摘要:
The invention concerns a chain magazine designed to hold the tools (8) of machining devices, the magazine comprising a continuous chain fitted with holders for the machining tools (8) and driven by at least two sprockets and guided by guide elements up to the point of contact with the pitch diameter of the drive or return sprocket. The chain magazine further comprises chain links (9) consisting of a connecting bar (10) and, joined to the bar, two tubular sleeve elements (11, 12) of different diameters which form the flexible couplings between the links. The tubular sleeve elements (11, 12) encircle each other with a small motion clearance, and tool holders are located in them coaxial to the coupling axis (Z). Each of the tubular sleeve elements (11, 12) has shaft-like zones (21, 22) with parallel surfaces spaced a certain distance apart and facing the central axis (19) of each tool holder. The shaft-like zones (21, 22) form, in the insertion or removal position of the chain coupling, an open insertion or removal route (23). The invention can call, in addition, for the outer sleeve element (12), which encircles the smaller-diameter inner sleeve element (11), to have an opening, extending along part of its circumference, of the same width as the connecting bar (10).
