Abstract: A flexible fixture system and method wherein a single fixture system can accommodate and hold a plurality of different workpieces, i.e. the various workpieces comprising the different flight surfaces of a wing. The flexible fixture system comprises a plurality of posts each including a plurality of different contoured formers, one former for each of the different workpieces to be accommodated and held by the flexible fixture system. Depending upon which workpiece is to be held by the fixture system, the required former on each post is selected automatically and moved into position for operative association with the workpiece. The contoured formers include powered clamps for holding details to be fastened to the workpiece. Each post of the flexible fixture system also includes a plurality of holding devices, such as suction cup type devices, which are moved into position to hold the workpiece and maintain its curvature.

Abstract: A printed circuit board is aligned to its mounting plate by using cutouts already cut for electronic components. A top plate with a notched location block and two edge locators is placed on top of both the printed circuit board and the mounting plate so that the notched block straddles two cutouts on the board and the mounting plate. At the same time, the two edge locators are placed inside the two matching cutouts. An eccentric cam is used to move a pressure plate that slides on top of the top plate and pushes both the circuit board and the mounting plate with spring action. The cam is turned until the edge locators hit the edges of the cutouts, aligning the printed circuit board to the mounting plate.

Abstract: In assembling a vehicle body frame for a motorcycle by welding front and rear frame subassemblies to each other, the following steps are carried out: a step of positioning left and right rear portions of the front frame subassembly by a pair of front positioning device movable at least in a widthwise direction of the vehicle body frame, a step of clamping a head pipe by a front clamp device which is capable of being moved in vertical and longitudinal directions of the vehicle body frame and is capable of being tilted longitudinally, a step of positioning left and right rear portions of the rear frame subassembly by a pair of rear positioning device movable in the longitudinal, widthwise and vertical directions of the vehicle body frame, a step of clamping left and right front portions of the rear frame subassembly by a pair of rear clamp means movable in the longitudinal, widthwise and vertical directions of the vehicle body frame, and a step of welding the front and rear frame subassemblies to each other.

Abstract: A method of making car bodywork, the method including a step of assembling body sides (4a, 4b) to an underbody (1), the underbody (1) including a rigid engine compartment (2) at one end and being placed in an assembly station in a precise position determined in an orthogonal frame of reference having directions X, Y, and Z, the method consisting: in putting the body sides (4a, 4b) into position and holding them in position in the frame of reference of the station by means of two parallel tools (13, 14) each co-operating with a respective body side (4a, 4b), and at least one transverse tool (11) extending transversely to said parallel tools, the three tools being connected to one another and to the X, Y, Z frame of reference of the station in such a manner that the transverse tool (11) is placed and held in a position that is precise and locked in the frame of reference and that it forms a spacer and bracing tool in the Y direction for the two parallel tools (13, 14) in a zone that is remote from the engine co

Abstract: A system for mounting a slab substrate in a three-dimensional modeling machine includes two parallel rails positioned on opposite sides of a modeling platform. A blade extends along each rail, each blade having an inward-facing knife edge. A slab substrate having a width which approximates the distance between the two rails and having slits in its sides is loaded in the machine by lining up the slits, respectively, with each blade and pushing the substrate towards the rear of the platform as the knife edges cut into the substrate. Preferably, the platform includes a rear stopper to stop rearward motion of the substrate. The platform preferably also includes a retaining means at its front edge that is actuated to lock the substrate into place on the platform during modeling. The substrate is removed from the platform by deactuating the retaining means, if any, grasping the substrate, and sliding the substrate towards the front of the platform.

Abstract: To produce a flanged pipe unit, a separate flange is put on a pipe and then the pipe is subjected to a punching to achieve an interlocked connection between the flange and the pipe. The flanged pipe unit produced by the method of the invention comprises a metal pipe including a larger expanded portion, a smaller expanded portion and a raised portion which are axially aligned so that the smaller expanded portion is placed between the larger expanded portion and the raised portion; and a metal flange having a through bore through which the pipe passes, the through bore including a larger diameter portion, a smaller diameter portion and a tapered end portion which are axially aligned so that the smaller diameter portion is placed between the larger diameter portion and the tapered end portion.

Abstract: An aircraft engine shipping system includes a frame assembly for supporting the aircraft engine, and a cradle assembly mounted on the frame assembly for securing the aircraft engine to the frame assembly. The frame assembly includes shock absorbers to provide continual shock absorption to an aircraft engine loaded thereon. The shipping system may be configured in either a truck or air transport mode. In the truck transport mode, the aircraft engine is secured to the cradle assembly by an aft ring which attaches to the aft portion of the aircraft, and a pair of cradle arms which attach to the forward portion of the aircraft engine. In the air transport mode, the aircraft engine is attached to the cradle assembly by the aft ring, and a forward ring which attaches directly to the fan of the aircraft engine. In the air transport mode, the cradle arms are disconnected from the aircraft engine and rotated away from the engine in a stowed position.

Abstract: A weld seam opening regulator for use in constricting cylindrical structures, including a frame, first and second wheels for riding on a first edge of a band of metal, a third wheel for riding on a first edge of a cylindrical portion of the structure, and a fourth wheel for riding on an inner surface of the cylindrical portion and maintaining a minimum weld spacing between the band and cylinder. Also, an adjustable bottom roller rides on a second edge of the metal band urges the metal band toward the cylindrical portion of the structure.

Abstract: A method and apparatus for manufacturing wing spars includes a fixture that holds spar webs for drilling and edge trimming by accurate numerically controlled machine tools using original numerical part definition records, utilizing spatial relationships between key features of detail parts or subassemblies as represented by coordination features machined into the parts and subassemblies, thereby making the parts and subassemblies intrinsically determinant of the dimensions and contour of the wing.
