The application discloses an
aviation aircraft accessory casing pipeline high-precision
assembly adjusting device and method, and belongs to the field of precision
machining. The device comprises: a reference positioning
assembly containing a positioning seat (4) and an angular pin (5), which is used for accurate positioning with a casing mounting seat; a space extension positioning
assembly, one end of which is connected with the reference positioning assembly, and the other end of which extends to the space position of a pipeline to be adjusted to reproduce an interface
coordinate vector; and a pipeline interface positioning pin (6, 7, 17), which is movably installed at the end of the space extension positioning assembly and is used for cooperating with a pipeline port to check the precision of the pipeline port. The method steps are as follows: fixing the device on the casing; inserting the positioning pin into the pipeline port; if all the positioning pins can be inserted freely and the end faces are flush, the pipeline is qualified; otherwise, the pipeline is repaired and rechecked. The application can accurately control the space position of the pipeline, realize high-precision stress-free
butt joint, greatly shorten the assembly period, build a quantitative
control system, and improve the reliability and safety of the pipeline
system.
