Space orientation computing method for numerical control bracket

Abstract

The invention relates to a space orientation computing method for a numerical control bracket, which comprises the following steps of: 1, processing three-dimensional digital analogy of each part; 2, defining a fixed mechanism and a moving mechanism in each digital analogy; 3, setting a drive command for a multiple axis movements of a numerical control bracket; 4, simulating whether each axis movement accords with an actual condition; 5, correcting a movement zero point of the digital analogy of the numerical control bracket; 6, enabling a spindle axes of an automatic drilling and riveting machine to be coincident with a normal line of a riveting point and the riveting point to be coincident with the center of a pressure foot bush; 7, refreshing the digital analogy; 8, figuring out data of five axes of the numerical digital bracket and data of a lifting position and a rotating angle of a lower riveting head under the condition of automatic drilling and riveting on any point on the surface of an airplane; 9, carrying out collision checking and batch output on space orientation data; and 10, carrying out numerical control programming to ensure that the automatic drilling and riveting machine continuously operates. According to the space orientation computing method, the numerical control system can automatically operate according to the space orientation data, and the airplane on the numerical control bracket meets the working requirements of the automatic drilling and riveting machine on the space.

Description

technical field [0001] The invention relates to a space positioning calculation method for a numerical control bracket, which is a method for calculating positioning data of a numerical control bracket of an aircraft product under space positioning conditions. Background technique [0002] The current assembly of aircraft products is gradually developing towards digitalization to replace traditional manual assembly methods. Automatic drilling and riveting machines have been used on aircraft assembly lines, but aircraft products must meet the requirements of the main axis of automatic drilling and riveting machines when processed on automatic drilling and riveting machines. Drill vertically into the surface of the aircraft product. Since the surface of the aircraft product is hyperbolic and irregular, the spatial state of the aircraft product must be continuously adjusted to level the riveting points during processing. The previous adjustment was performed manually, relying on...
