    摘要： The invention relates to a tool changer for machine tools, comprising at least two tong-type grippers (16), whose limbs (17, 18) are configured to engage in the annular groove (23) at the wider end of a tool taper. The grippers (16) are axis-symmetrically mounted on a support (13) that can be rotated about its center axis (15), the bit pointing outward. The support (13) is mounted on a support construction (11, 12) that is provided with a drive for displacing the support. In order to prevent the tool taper from prematurely coming loose from the chuck disposed in the work spindle and to allow for a faster tool change, at least one limb (18) of the grippers (16) is extended to give a salient retaining finger (20).

    摘要： The invention is directed to a method and apparatus for selectively and simultaneously drilling a plurality of holes in thin panels such as printed circuit boards, while providing for automatic changing of the drill bits, individually or plurally, as required. A tray of drill bits (42) is driveable in X and a row of vacuum pickers (20) are driveable in Y, so that the various bit locations of the tray (42) are addressable by such X-Y positioning, and selectable vacuum pickers (20, 34) are extensible and retractable so as to pick and place the drill bits (74) at various matrix locations of the tray (42). The vacuum pickers (20, 34) also are extensible and retractable through corresponding tray openings (48) in order to deliver replacement bits (74) to, and retrieve used bits from, a flipper assembly (111) associated with each drilling module (50). Each flipper assembly (111) transfers bits back and forth between the vacuum picker and drill without having to transfer either bit through the opening in a footprint portion of the pressure foot (90) which engages the materials to be drilled during the drilling operation. Thus, the footprint opening may be made smaller in diameter than depth stop collars or the like which are of greater diameter than the working portion of the bit which is advanced through the footprint opening during drilling. This smaller footprint opening of the pressure foot is for minimizing or eliminating hole "smears" and for overcoming problems normally associated with the so-called "oil can effect".

    摘要翻译： 本发明涉及一种用于选择性地同时钻孔诸如印刷电路板的薄板中的多个孔的方法和装置，同时根据需要单独地或多次地自动改变钻头。 钻头盘（42）可在X中驱动，一排真空拾取器（20）可以在Y中驱动，使得托盘（42）的各种钻头位置可通过这种XY定位来寻址，并且可选择的真空拾取器 20，34）是可伸缩的，以便将钻头（74）拾取并放置在托盘（42）的各种矩阵位置。 真空选择器（20,34）也可通过对应的托盘开口（48）伸展和缩回，以便将与每个钻孔模块（50）相关联的导板组件（111）的更换钻头 ）。 每个导板组件（111）在真空拾取器和钻头之间来回传送钻头，而不必将钻头通过压力脚（90）的覆盖部分中的开口传送，钻孔部分在钻井操作期间与待钻探的材料接合。 因此，足迹开口的直径可以比深度止动环等更小，其比在钻孔期间通过足迹开口前进的钻头的工作部分的直径大。 压脚的这种较小的占地面积的开口是用于最小化或消除孔“涂抹”并克服通常与所谓的“油可以影响”相关的问题。

    摘要： A machine tool (1) consists in a pair of slide ways (2) set apart one from another and extending parallel with a longitudinal axis (A), a machining station (3) between the slide ways (2), presenting a first zone (3a) and a second zone (3b) adjacent one to the other, and a travelling gantry (5) set in motion along the slide ways (2) and carrying a machining head (8) positionable in the first and second zones (3a, 3b). Installed alongside at least one of the slide ways (2) and containing a supply of tools (9) attachable to the machining head (8) is a magazine (12) equipped with a first changer element (14) positioned to coincide with the first zone (3a) of the station, and a second changer element (15) positioned to coincide with the second zone (3b), so that whichever of the two zones (3a, 3b) the machining head (8) happens to occupy at any given moment, the tool (9) currently in use can be replaced with a tool from the magazine (12) by the relative changer element (14, 15) with minimal loss of time.
