Positioning and supporting auxiliary tool for precise drilling in aircraft

Abstract

The invention relates to a positioning and supporting auxiliary tool for precise drilling in an aircraft. The positioning and supporting auxiliary tool comprises a sliding rail, a sliding block, two electric telescopic rods, a connecting shaft, a longitudinal sliding rail I, a longitudinal sliding rail II, a sliding support and a gun drill clamping mechanism, wherein the longitudinal sliding railI and the longitudinal sliding rail II are horizontally arranged in the front-back direction. The gun drill clamping device is used for clamping and fixing a gun drill at a position matched with the height direction of a drilling position. The sliding support slides left and right to enable the longitudinal sliding rail I to slide along the connecting shaft through a linear bearing, so that the longitudinal sliding rail II slides along a guide rail groove I of the sliding rail through the sliding block, the gun drill can be conveniently adjusted to a to-be-drilled position in the left-right direction, the gun drill can be pushed to enable the sliding support to slide towards the inner side along the longitudinal sliding rail I and the longitudinal sliding rail II, and drilling or reaming operation can be carried out by the gun drill in the direction perpendicular to a drilling plane. The drilling efficiency and the drilling precision are improved. An operator only needs to hold the gundrill by hand and move the gun drill towards the inner side to complete drilling. The convenience of operation in a narrow space of a front storage cabinet is improved.

Description

technical field [0001] The invention relates to the technical field of aircraft refitting tools, in particular to a positioning support auxiliary tool for precise drilling on an aircraft. Background technique [0002] When carrying out work such as WiFi modification of Boeing 737 series aircraft, it is necessary to drill holes in related components such as lockers and place built-in nuts, etc. The purpose is to provide a support base for the added components, because the space of the aircraft is limited, such as WiFi During the modification, it is necessary to add a space for the WiFi device in the front locker, so it is necessary to drill holes in the cabinet and place the built-in nuts, but the space required for the modification is small, and it is difficult for the staff to specify the location for precise Drilling and reaming, due to the narrow space, it is extremely difficult for the staff to operate, and it cannot be guaranteed during the process of drilling and advan...

[0002] When carrying out work such as WiFi modification of Boeing 737 series aircraft, it is necessary to drill holes in related components such as lockers and place built-in nuts, etc. The purpose is to provide a support base for the added components, because the space of the aircraft is limited, such as WiFi During the modification, it is necessary to add a space for the WiFi device in the front locker, so it is necessary to drill holes in the cabinet and place the built-in nuts, but the space required for the modification is small, and it is difficult for the staff to specify the location for precise Drilling and reaming, due to the narrow space, it is extremely difficult for the staff to operate, and it cannot be guaranteed during the process of drilling and advancing. Drilling in this small space with built-in nuts will cause drilling due to the working limitations of the staff. It cannot be kept perpendicular to the drilled plane, and it is difficult for the staff to keep the trajectory of the drilling action always perpendicular to the drilled plane during the drilling work, which will greatly increase the probability of drilling failure, which will not only cause Additional repair work will even cause certain economic losses, and the accuracy of drilling cannot be guaranteed, resulting in more errors
