Problems solved by technology

Due to the very narrow operating space, it has brought great difficulties to the on-site processing of high-lock bolt holes. In addition, due to the influence of factors such as bushing clearance and human operation errors, it is very easy to cause damage to the overall fuel tank of the aircraft ...

Embodiment Construction

[0023] The high-precision porous member mentioned in the method of the present invention has multiple high-precision bolt holes with high precision requirements, and the reassembly refers to the assembly process of replacing the old high-precision porous member with a new high-precision porous member. The method of the present invention abandons the on-line processing method of all high-lock bolt holes on the new high-precision porous components of the original process, and firstly performs off-position processing of prefabricated holes on the new high-precision porous components, and then fixes the components through positioning, setting the knife with a set, and hole-to-hole precision Reaming and other steps, the prefabricated holes are processed into high-lock bolt holes that can accurately match the original high-lock bolt holes on the assembly base, and then high-lock bolts are driven into each high-lock bolt hole of the high-precision porous component and tightened.

Abstract

The invention discloses a reassembly method of a high precision porous component. The high precision porous component is provided with a plurality of high-lock bolt holes, each high-lock bolt hole and an assemble place substrate are operated in an accurate counterpoint mode when the high precision porous component is assembled. The high precision porous component is characterized in that the method includes the following steps: a, dislocation processing of prefabricated holes; b, locating fastening of a novel high precision porous component; c, precision reaming of the prefabricated holes; and d, installation of high-lock bolts. According to the reassembly method of the high precision porous component, the prefabricated holes are required to be only renovated and processed on line, original hole manufacturing work which needs to be done in a narrow space and is difficult to operate is mostly transferred to a working environment which is spacious and easy for operation, the repair cycle is greatly shortened under the premise that assembly requirements are met, and assembly operation difficulty is reduced.

Description

technical field [0001] The invention relates to an assembly method of precision components, in particular to a reassembly method of high-precision porous components. Background technique [0002] For some precision mechanical equipment, some high-precision components need to be replaced after the use time reaches the allowable period. The replaced components must fully meet the assembly technical conditions of the original equipment to meet the precise reassembly requirements. For example: a strut support for an aircraft is fixed on the fuel tank of the aircraft by nearly a hundred high-lock bolts and several standard bolts. When the aircraft maintains and replaces the strut support, how to ensure that the newly processed strut support It is a very tricky job to accurately match the high-lock bolt holes on the seat with all the high-lock bolt holes on the aircraft fuel tank. If the high-lock bolt holes on the strut support are processed off-site, even if all the holes meet ...
