A method of assembling thin-walled curvilinear components to a bulkhead offers a cost-effective, time-saving process of manufacture. Each component includes a faying edge configured to be aligned with respect to the other. A first component and the bulkhead are preassembled. In one approach, a second component is clamped about the bulkhead for a preassembly measurement of radial gaps between the faying edge of the second component and the bulkhead. An average value of the radial gaps is calculated, and a specific shim thickness corresponding to the calculated average gap value is selected. The second component is unclamped, and a plurality of shims, each having the selected thickness corresponding to the calculated average gap value, is applied about the bulkhead. The second component is then permanently secured to the bulkhead over the shims, with respective faying edges of the first and second components fixed in radial alignment with each other.

A splicing structure, a splicing table, and a splicing and fitting device are provided. The splicing structure includes: a splicing adjustment component, a splicing alignment component, and a splicing base. The splicing adjustment component and the splicing alignment component are connected to the splicing base; and the splicing adjustment component is configured to support at least two to-be-spliced pieces; the splicing alignment component is configured to align the at least two to-be-spliced pieces to a first reference site. The splicing adjustment component is further configured to drive at least one of two adjacent to-be-spliced pieces in the at least two to-be-spliced pieces to move relative to the first reference site, to enable the two adjacent to-be-spliced pieces to be close to or far away from each other.

A tool to manage flanges during installation and dismantling of flanges includes a first ring support structure and a second ring support structure spaced apart along a tool axis. First and second mechanical arms are retained on the first and second ring support structures. Each of the mechanical arms has an extendible arm joint that is operable to adjust an axial distance between the first and second ring support structures. A guide shaft is coupled to the first and second ring support structures. The guide shaft is positioned to guide a relative movement between the first and second ring support structures during operation of the extendible arm joints of the first and second mechanical arms.

A system for mounting a door hinge to upper and lower mounting portions of front and rear pillars of a vehicle body being transferred along a vehicle transfer line. The system includes: a jig frame installed to reciprocate in a vehicle width direction through a driving unit on a base frame outside the vehicle transfer line; a rotation index installed on the jig frame and rotatable by a predetermined angle through a servomotor; a vertical rotation shaft formed as a polyhedron having a cavity and coaxially connected to a rotation center axis of the rotation index along an up and down vertical direction; and a pair of clamping units installed through a mounting plate to a base plate fixed to each side of the vertical rotation shaft, the pair of clamping units being disposed at upper and lower portions of the mounting plate and configured to clamp the door hinge.

A method for assembling a beam combiner array including providing an array block having a back wall, a front surface and a plurality of aligned channels extending from the back wall to the front surface, where a bore extends through the back wall and into each channel, and providing a lens array including a plurality of lenses. The method further includes securing the lens array to the front surface of the block so that one of the lenses is aligned with each channel and threading a separate hollow core fiber through one of the bores in the back wall so that an end of the fiber is positioned within the channel. The method also includes aligning each fiber to the lens array so that a beam that propagates down the fiber is emitted into the channel, focused by the lens and emitted from the array as a collimated beam.
