Embodiment Construction

[0022] The invention will now be described more fully with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and describe the invention The scope of this is fully conveyed to those skilled in the art. Like reference numerals refer to like elements throughout.

[0023] Referring to Figure 1, there is shown a machine 20 in accordance with a preferred embodiment of the present invention. The machine includes a pair of rails 22, 24 to which a plurality of attachment devices, preferably in the form of vacuum cupholder assemblies 26, are releasably secured at spaced intervals along the length of each rail. The rails 22, 24 preferably have a width substantially greater than their thickness, so that they h...

Abstract

The present invention discloses a flexible rail drilling machine that employs a pair of rails that are flexible in one direction to accommodate non-flat workpiece surfaces and are substantially rigid in a direction parallel to the workpiece surface of. The rails are attached to the workpiece by vacuum cup holders spaced along each rail. The X-axis bracket is slidably installed on the track through rollers mounted on a flexible spring plate fixed to the bracket. A drill or other device to be positioned is mounted on a Y-axis carriage that is slidably connected to an X-axis carriage. The three-dimensional workpiece surface is mathematically transformed into a two-dimensional flat pattern, and the positioning of the carriage is controlled based on the flat pattern.

Description

technical field [0001] The present invention relates to machines for drilling holes or performing other machining operations on large workpieces, such as panels or similar structures constructed in simple or composite profiles, such as aircraft wings and fuselage sections. More particularly, the present invention relates to a flexible rail machine and method for positioning a tool such as a drill, stamper, or similar device relative to a workpiece by reciprocating a machining module along a rail mounted on and positioned to the workpiece processing module. Background technique [0002] The problem of accurately drilling holes in large workpieces such as aircraft wings and fuselage panels or other types of structures has always been a challenge to the aircraft industry and other industries, and so far has not provided a fully satisfactory, The solution for a wide range of workpiece configurations. Larger stationary machines, such as five-axis drills, can be used for some ty...
