Abstract:
A protective cover for a zone of a machine tool, in which a machining part moves along an operating path, preferably extending on a single plane, in said zone; the cover comprises a plurality of cover elements consisting of a fixed cover element which can be fixed to the machine, a mobile element connected to the machining part and a plurality of mobile cover elements positioned between the fixed cover element and the mobile cover element which is connected to the machining part; the cover elements are closed in a pack, each with a window, and are arranged according to decreasing size and lie around the machining part, connected to one another by a first and a second support rod, at a given distance from one another and with respective mobile cursors on the rods so as to guide the mobile cover elements in a direction parallel with and a direction at right angles to the rods, during movement of the machining part, keeping the machining zone covered.
Abstract:
For a machine for running pairs of gears together, e.g., for lapping or testing one pair at a time, there is provided an incoming magazine, an outgoing magazine, a conveyor device which moves gear pairs toward the front of the incoming magazine; a conveyor device which moves gear pairs toward the back of the outgoing magazine; a transfer device which moves two pairs of gears across the machine at once: taking one pair from the machine''s work station and another from the front of the incoming magazine and shifting these pairs, respectively, to the front of the outgoing magazine (or to a reject chute) and the machine''s work station. The gears are oriented in the incoming magazine so they will mesh when mounted at the work station. The server is responsive to tests performed at the work station to reject and replace any damaged or improperly paired gears or any gear pair improperly installed at the work station and to indicate the reaons for rejection on a register which shifts as additional pairs are rejected so the machine operator can quickly discern which gear pair was rejected for which reason. A telescoping cover encloses the work station during the lapping operation to prevent contamination of the transfer mechanism.
Abstract:
The present invention relates to a loading station comprising a loading region which is accessible from a loading side and from a machine side and comprising two door elements movable along a guide from a machine position in which they release the machine side and close the loading side into a loading position in which they release the loading side and close the machine side, wherein the door elements overlap at least partially in the loading position and/or in the machine position so that, on an opening procedure of the machine side and/or of the loading side, the machine side and/or the loading side only starts to open when the respective other side has closed at least partially.
Abstract:
A protective cover for the work area of a machine tool having a plurality of frame-like segments disposed so as to be limitedly shiftable within each other and respectively provided with a sealing strip on at least one edge. A plurality of connecting elements formed as slidable lattice grates connect the frame-like segments, the respective link pins of the slidable lattice grates being fixed to a respective rear segment of a segment. For simplified assembly and removal of the protective cover the slidable lattice grates are detachably fixed to the frame-like segments.
Abstract:
A machine tool comprising a machine base having a first side comprising a first planar surface and a machine column movable along an arcuate path on the first planar surface. The machine further comprises a first spindle movable in a first linear direction and being rotatable about a first axis of rotation. The machine further comprises a machine turret located on a second planar surface of the machine base first side. The machine turret is angularly movable about a pivot axis. The machine turret includes a second spindle positioned within the turret with the second spindle being rotatable about a second axis of rotation and being movable in a second linear direction.
Abstract:
A protection device (D) of the driving means of a mobile element (O) against the cuttings projection of a machining machine tool comprising a driving section (P1) and a machining zone (P2) of the type that defines a protection wall that, being interdependent from the mobile element (O) that goes through it, separates the driving section (P1) from the machining section (P2). The protection wall is constituted by a plate (100) interdependent from the cross-through part of the mobile element (O) and having a free translational motion on a disk (200) rotating freely with respect to a cabin (300) and the rotation axis (A) of which is shifted with respect to the displacement axis (B) of said mobile element (O). A first displacement window (210) in the disk (200), and a second displacement window (310) in the cabin (300) are provided wherein both displacement windows (210 and 310) are arranged with respect to each other in such a way that the displacement of the mobile element (O) in said second window (310) according to a plane perpendicular to the rotation axis (A) of the disk (200) simultaneously causes the sliding of said plate (100) on the disk (200) and the rotation of the latter, so that said translational displacement of the plate (100) and the rotation of the disk (200) occlude the opening of both displacement windows (210 and 310).
Abstract:
An adjustable power transmitting device comprising a rotary input shaft mounted for rotation about a first axis and an output shaft mounted for rotation about a second axis. The output shaft is also mounted for pivotal movement about at least two non-parallel axes so that the position of the output shaft can be adjusted about both of these axes. The input shaft is drivingly coupled to the output shaft so that the input shaft can rotate the output shaft in all positions of the output shaft about the two non-parallel axes.
