Description

Technical Field

[0001] The utility model relates to the technical field of aircraft manufacturing, in particular to a rapid hole-making tooling for an aircraft through-cabin equipment cabinet. Background Technique

[0002] The installation of the aircraft through-cabin equipment cabinet is different from the open area. Due to many adverse factors such as extremely small visible area and small operation space at the position of the equipment cabinet pull rod, the hole-making is very difficult. At present, it is mostly the case of using the equipment cabinet body for matching drilling.

[0003] The above method has the following disadvantages:

[0004] (1) The equipment cabinet body is heavy, and each handling and placement is very time-consuming and labor-intensive;

[0005] (2) The hole-making process needs to go through four major parts: planning hole-making, matching and marking points, matching drilling and reinstalling and inspecting. The whole process needs to go through 3 times of handling of the equipment cabinet. Due to the heavy weight of the equipment cabinet body, multiple handling is easy to cause irreversible damage to the cabinet body structure;

[0006] (3) The paint used for marking the hole-making points is easy to cause irreversible erosion damage to electronic devices such as connectors and transfer modules in the equipment cabinet;

[0007] (4) The metal chips generated during hole-making are easy to float into electronic devices such as connectors and transfer modules in the cabinet, causing short circuits and leakage between wires, etc., thus burning out the equipment, and causing potential and devastating disasters to aircraft tests and flights;

[0008] (5) If the metal chips generated during hole-making are not processed in time and float around or accumulate too much, they will cause foreign objects in the cabin, affecting the performance and safety of the aircraft;

[0009] (6) Different from ordinary hole-making, cabinet hole-making needs to take into account both the matching of the cabinet body and the aircraft structure and reduce the hole-making over-tolerance, so it needs to be operated by experienced personnel, occupying too many professional personnel resources.
