The X-ray inspection device and the X-ray inspection method according to the present invention are configured to hold an object to be inspected irradiated with an X-ray from an X-ray irradiation device, uses a swinging device for performing swinging motion of tilting the object to be inspected at an arbitrary angle and in an arbitrary direction, images the X-ray that passes through the object to be inspected in an X-ray detection device and extracts data of a desired cross section from the X-ray image of the X-ray detection device in a control device.

X-ray inspection apparatus and X-ray inspection method

The traverse apparatus of the subject invention is provided at the end of the main base 24 with a control box 38 having electromagnetic valves 57, 58, relief valves 59, 60, and manifold 61; and, one or more connectors 54 affixed at one end to sliding base 28 and at the other end to a separate sliding base 70. By these elements, the main body having cylinder 32 is separated from the rail guides 22, 23, the work of replacing a worn cylinder 32 is made easy, conveyance can be expedited, and the head mounting bases for attaching working heads can be increased readily.

Traverse apparatus

Method and apparatus for shaping the coil ends for electric appliances wherein convex shapes are formed in the end portions of a plurality of types of coils, and the number or different shape of the convex shapes in each coil is selected to simplify the distinguishing of the plurality of end portions extending from each coil from each other and to prevent wiring errors in the connection of the end portions.

Method of shaping coil ends of an electric appliance

An apparatus for forming an interpole crossover wire in a winding apparatus for winding a wire around a spool to form stator coils. The circular arc motion of a pair of pawls is performed by a piston-cylinder device driving an adjustable link mechanism. By adjusting the dimensions of the link mechanism the length of the circular arc motion of the pawls can be adjusted.

Apparatus for forming an interpole crossover wire between stator coils

A wire cutting apparatus for use in a winding machine which winds an electric wire or the like round a spool, wherein one terminal wire leading to the coil from the terminal wires formed through the drawing operation of the wire is cleared to remove the entwinement with the cutting arm, the other terminal wire leading to the nozzle of the flyer is descended together with the clamp pawl, with the result that the terminal wire is not involved in the flyer even if the terminal wire is floated after the clamp pawl has released the terminal wire.

Wire cutting apparatus for wire winding machine

An improved coil winding apparatus, for example, for stators of electrical machines and the like, in which undesirable rising or floating of coils accommodated in a coil inserting jig is prevented by the employment of a rockable stop which permits the coils formed above the stop to be pushed onto the lower part of the coil inserting jig by the rocking function of the stop, and which cannot pivot past a horizontal position, thereby blocking floating or rising of coils off the coil inserting jig.

Coil winding apparatus

A coil winding apparatus comprising a spool, a flyer for effecting relative revolution around the spool to wind the wire around the spool, a continuous wire passage for guiding the wire to the flyer, a bobbin with the wire wound therearound, and a feeding means for compulsorily feeding the wire, wound around the bobbin, to the flyer through the wire passage, the continuous wire passage through which the wire is extended to form the coil allowing the wire to be automatically fed into the wire passage, whereby the time required for the wire inserting operation to be effected during the replacement of the wire can be considerably shortened.

A holding device used in a drawing-in device for inserting winding coils into a stator core of an electrical machine from a transfer tool carrying the winding coils. The holding device includes a stationary cam plate defining therein a cam groove and a pusher block supporting a holding down-plate, which pusher block bears guide rollers cooperating with the cam groove so that the holding-down plate is guided to the stator core disposed on the transfer tool and then applies a force in the direction of the stator core axis about which an associated rotor of electrical machine is rotated.

Stator core holding device for fabricating a stator assembly for an

A method for fabricating stator assemblies of electrical machines and an apparatus suitable for carrying the method into practice, wherein a plurality of transfer tools receiving wound coils and inserting the coils into stator cores are transported by conveyors in two identical closed paths arranged symmetrically. Located along each closed path are a plurality of main coil winding devices for winding main coils and transferring them to the transfer tools, a plurality of auxiliary coil winding devices for winding auxiliary coils and transferring these coils to the transfer tools, and a transfer tool indexing device interposed between the main coil winding devices and the auxiliary coil winding devices for indexing the auxiliary coils with the main coils. A drawing-in device common to the two closed paths simultaneously draws the main and auxiliary coils on each transfer tool into stator grooves. The main coils wound by one of the main coil winding devices and the auxiliary coils wound by one of the auxiliary coil winding devices are successively transferred to each transfer tool while the latter moves in each closed path. The coils are simultaneously drawn into the stator grooves by the drawing-in device in one operation.
