Abstract:
Apparatus for orienting a work-piece, particularly a metal girder and holding it in position ready for machining, particularly drilling, comprises a machining unit displaceable with respect to a fixed bed. At least one deformable member is provided on which the work-piece rests and this member is fixed by its two ends to the tops of two substantially vertical bars. These bars are capable of sliding vertically and independently with respect to the bed and the latter includes a table on which the work-piece rests. The table is arranged in front of the machining unit. The deformable member or members generally comprise chains, but may be cables either of metal or textiles. Different means for clamping the work-piece are described.
Abstract:
A method and apparatus for tapping into a pressurized multiple strings of coaxially situated tubulars for wells and/or platforms which have overturned wherein the tapping occurs underwater via a diver or remotely operated vehicle. The assembly includes a tapping tool connectable to the tubular via a saddle connection and an adjustable tapping clamp with adjustable support/locking feet, compression plate with view ports, and angularly adjustable hot tapping system, along with a drill/saw system.

Abstract:
Portable robot for carrying out the drilling process in the assembly of aeronautical components which are secured on a support known as a stand. The robot comprises a displaceable platform in order to permit it to be located close to the stand, and an arm, which supports a frame comprising a beam intended to support a drilling head that can be displaced in the three axes.
Abstract:
The apparatus for boring a web of a section. The apparatus is provided with a boring device which is opposed perpendicular to the web of a clamped section and arm plates for supporting the boring device. The apparatus further has a clamping mechanism for clamping the section from each side thereof along the direction substantially parallel to the rotational axis of the boring device.
Abstract:
An adaptor mounting a drill stand on an I-beam comprises a base plate which is clamped to a flange of the beam by clamping arrangements. A table of the drill stand is then bolted to cross-members slidably mounted on the base plate. In another arrangement, the pillar of the drill stand 11 is fitted in a collar housing which is slidably mounted on a base plate. In yet another arrangement, the pillar of the drill stand is mounted on the flange of an I-beam by opposed jaws which are slidable along the pillar and locked in position by screws.
Abstract:
A drilling tool is adapted for incorporation into a riveting robot. For this purpose, the drilling tool with its spindle head is mounted on a slide that is motor driven for displacement in the Z-direction of an XYZ coordinate system. The slide in turn is mounted on a console provided with a flange to be secured or docked to the riveting robot. The console is rotatable about its longitudinal axis that extends perpendicularly to the drill spindle axis and intersects the latter approximately in the center of the spindle axis. The drill spindle is rotatably mounted in a spindle head and carries a drive wheel approximately in the center between the spindle ends. The drive wheel is meshing or cooperating with a power transmission train from a motor that is also secured to the slide and moves up and down with the slide and thus with the spindle head. Another motor drives the up and down movement of the spindle head. This type of arrangement permits positioning the drill bit in difficult locations. Overhead drilling, sideways drilling is possible in addition to the normal downward drilling.
Abstract:
A workpiece drilling machine includes to be moved to any of several drilling locations along the workpiece. A plurality of indexing detents is formed along the rail coinciding with each drilling location. A cam follower on the drill carriage is engageable with the detents to coarsely position the drill carriage. An index-cancelling device is associated with each detent and controllable by a preprogrammed input device to determine which of the detents is to be available for engagement by the cam follower. The programmed input device has a visual marking thereon corresponding to the information encoded therein and a visually perceptible status readout is controlled by the index-cancelling means to permit visual verification that the index-cancelling devices are arranged in accordance with the desired pattern. An accurately positioned bearing is located at each drilling location and is engaged by a fine-positioning pin mounted on the drill carriage prior to the start of drilling to provide fine positioning of the drill carriage. A workpiece locator device is included that allows the workpiece to be positioned in one of several discrete positions relative to the rail. A clamping system located in the drill carriage clamps the workpiece in position referenced to the drill carriage to eliminate the effects of warp and twist in the workpiece on hole location.
Abstract:
A drilling-conveying apparatus for the layout and fabrication of structural beams and girders comprising, dual mobile opposite hand co-ordinated drilling-conveying units, mounted on a common longitudinal supporting-guiding track and symmetrically spaceable thereon to any selected lateral spacing by a common right and left threaded relocating shaft, oppositely threaded through the bases of the said dual opposed units and longitudinally restrained by a mid-located floor-mounted anchor-bearing located between the rails of the said track, with the operating faces of the said units facing inwardly towards said anchor-bearing, each of said co-ordinated units having an integral vertical wall on the outer end of said base, vertically guiding a low elevateable transversely-extending platen supporting and guiding transversely convergible dual drill heads holding plural horizontal drills for simultaneously drilling both shape flanges and an adjustableheight vise to locate, elevate and hold a raw shape for precise drilling, a longitudinal ram projectible through said wall to length-center shapes between said dual units, a stationary forwardly-overhung drill head with transversely-disposed plural vertical drills for simultaneous drilling of the shape web, an integral transversely-operable multiple-strand chain-link conveyor means to transport the shapes forwardly into and out of the operating area, and powered moving, elevating, rotating, operating and control means.
