Description

Technical Field

[0001] The invention relates to the technical field of aviation repair and production, in particular to a method for imitating hole processing of an aircraft tie rod. Background Art

[0002] Due to the influence of ocean, climate and other factors, the corrosion of aircraft bodies and their components of various types of naval aircraft has become an important issue for naval combat forces and related parties. Before this issue can be well resolved, some parts affected by corrosion must be replaced during factory overhauls; on the other hand, due to long-term use, the force causes the holes to deform, the bolts to loosen, and the pull rods cannot be used normally and need to be replaced.

[0003] However, during the manufacturing process of the pull rod, the maintainability of the part was not taken into consideration. During processing, the two parts were matched and then holes were made. The maintainability and interchangeability were extremely poor, and many holes of the parts that were connected and matched with each other had problems such as slanted holes. When the old holes were on the inside of the new parts, it was an unconventional hole matching. Mainly because of the obstruction of the new parts, the relative position of the holes in the old parts could not be seen, which caused great difficulties in the imitation hole processing and the cost of replacing the entire part was relatively high.

[0004] This method uses simple principles to perform hole-simulating machining.

[0005] Therefore, it is necessary to design a method for imitation hole processing of aircraft tie rods to solve the problem of poor subsequent maintainability and interchangeability caused by the original drilling in the production and manufacturing process. It can solve the problem of replacing various types of sleeve parts and realize the role of changing the replacement of a whole set into the replacement of a single part. Summary of the invention

[0006] The purpose of the present invention is to provide a method for imitation hole processing of aircraft tie rods to solve the problems raised in the above background technology.

[0007] To achieve the above object, the present invention provides the following technical solution: a method for imitation hole processing of an aircraft tie rod, comprising the following steps:

[0008] It includes an adapter, a type I bolt, an inner sleeve, a type II bolt, and an outer sleeve, and includes the following steps:

[0009] S1: Remove type I bolts and type II bolts;

[0010] S2: Make a conversion piece, the inner hole of the conversion piece matches the adapter, and the outer circle of the conversion piece is larger than the outer circle of the inner sleeve;

[0011] S3: Measure the position of the connection hole, mark it on the conversion part, and make process holes at the marked position;

[0012] S4: The conversion piece is fixedly mounted on the adapter so that the connection hole on the adapter can be observed through the process hole;

[0013] S5: Use the connection hole on the adapter to guide the imitation hole on the other side of the process hole on the conversion part;

[0014] S6: Match the inner hole of the conversion piece with the outer circle of the new inner sleeve to be replaced, and fix the conversion piece on the new inner sleeve;

[0015] S7: using the imitation hole on the conversion part to process the imitation hole of the new inner sleeve;

[0016] S8: Fix the new inner sleeve onto the adapter;

[0017] S9: By using the imitation hole of the new inner sleeve and the guiding function of the connecting hole on the adapter, the hole on the other side of the new inner sleeve is processed, so that the hole of the imitation new inner sleeve can be consistent with the old one.

[0018] In S2, the outer circle of the conversion piece is 10 mm larger than the outer circle of the inner sleeve.

[0019] The process hole in S3 is a single-side hole, which is 2mm larger than the original connection hole.

[0020] The new internal sleeve in S7 has a single-sided hole.

[0021] The connection hole positions in S3 can be multiple hole positions.

[0022] Compared with the prior art, the present invention utilizes the principle that the existing hole has a guiding effect on the drill bit, fully utilizes the guiding effect of the hole of the old part, and processes the hole of the new part so that the position of the hole of the new part can effectively match the old part, thereby solving the problems of poor maintainability and poor interchangeability; similarly, a conversion part similar to the new part is made with a hole one level larger on one side of the part, so that the hole on the matching part can be seen, and then the hole on the new part is reversely processed to ensure that the hole of the new part is consistent with the hole of the old part.
