Abstract

The invention relates to a radial positioning code disc which comprises a reference disc, a floating disc, a fixed disc, a check ring, a baffle ring, an outer sleeve and an inner sleeve. Accurate positioning of any radial position can be achieved, and the method is particularly suitable for field actual matching connection of complex pipelines and shafts. The positioning method is differential relative position positioning, so that initial positions do not need to be set for the reference shaft and the floating shaft, and the positioning method can be used for radial positioning of various structures such as shafts, pipelines, joints with threads and injection orifices on a machine. Rapid positioning of installation and maintenance is facilitated, and assemblability and maintainability are improved.

Description

technical field [0001] The invention relates to the technical field of shaft or pipeline assembly, in particular to a radial positioning encoder. Background technique [0002] There are various complicated pipelines, shafts, joints and nozzles on the aircraft. The pipelines on the aircraft are mostly rigid pipelines. At the same time, the joints and nozzles usually have the direction of radial positioning. At the same time, due to the complexity of the pipeline system and the requirement of interface connection between multiple functional modules, there are a large number of field adaptation and positioning operations of pipelines and joints in practical applications. [0003] In order to realize the radial positioning of shafts, pipes and joints, some positioning structures such as positioning pins, positioning holes and positioning bosses are used in the prior art. This positioning is rigid positioning, and positioning pins and positioning holes are preset on the parts. ,...
