Description

Technical Field

[0001] The utility model relates to the technical field of aircraft maintenance tools, and particularly relates to an auxiliary tooling for manufacturing positioning holes of waterproof floor mats in the front and rear passenger cabins of an aircraft. Background Art

[0002] There are many positions inside the aircraft where waterproof floor mats need to be laid. The thickness of the floor mat is between 5 - 10 mm according to different usage areas. For example, in the front and rear passenger cabin areas, the purpose of laying the waterproof floor mat in the front and rear passenger cabins is to prevent the aircraft structure from being corroded in the water sprinkling and leakage areas, ensure the safety of the aircraft and extend its service life. When inspecting the aircraft floor beam structure, it is necessary to remove the original laid waterproof floor mat, and the structure will be damaged during the removal process. After completing the maintenance task, a new waterproof floor mat needs to be laid, and it needs to be cut according to the shape and structure of the laying position and the positioning holes need to be made. Since the original removed waterproof floor mat is tightly bonded to the floor structure, it is prone to deformation and damage, and it is very difficult to cut and make positioning holes for the new waterproof floor mat with the help of the original waterproof floor mat. The positioning holes are mostly located at the edge of the waterproof floor mat material. When making the positioning holes, manual measurement is used, which is prone to inaccurate positioning holes, and it is easy to misalign with the prefabricated fixed holes on the aircraft floor, resulting in poor waterproof tightness and corrosion of the aircraft structure. Content of the Utility Model

[0003] In order to overcome the above deficiencies in technology, the utility model provides an auxiliary tooling that realizes accurate positioning and rapid production of positioning holes for waterproof floor mats, and improves work efficiency.

[0004] The technical solution adopted by the utility model to overcome its technical problems is as follows:

[0005] An auxiliary tooling for manufacturing positioning holes of waterproof floor mats in the front and rear passenger cabins of an aircraft, comprising:

[0006] A column, arranged vertically, with a support in the middle part thereof, and a through hole is arranged vertically in the support;

A plurality of hole-opening tools are arranged around the outer side of the turntable, and the axis of each hole-opening tool is perpendicular to the axis of the turntable;

[0010] The support plate is arranged horizontally and fixed to the lower end of the column. A positioning mechanism is provided at the lower end of the support plate and is inserted into the positioning hole of the aircraft cabin. The axis of the boring tool at the lowest end of the turntable when it rotates to the vertical downward direction is coaxially arranged with the positioning mechanism.

[0011] Furthermore, the above-mentioned driving mechanism includes a pressure rod rotatably installed at the upper end of the column through a rotating shaft, a spring sleeved on the driving rod, and a ball head Ⅰ provided at the head end of the driving rod. A chute is arranged along the length direction at the lower end of the pressure rod. The upper end of the spring is connected to the driving rod, and the lower end is connected to the support. When the spring is in a free state, the ball head Ⅰ is inserted into the chute and the boring tool on the turntable is located above the support plate.

[0012] In order to improve the operation convenience, a ball head Ⅱ is provided at the head end of the above-mentioned pressure rod.

[0013] Furthermore, the above-mentioned positioning mechanism includes a threaded head provided at the lower end of the support plate. The axis of the threaded head is arranged vertically. A threaded hole is provided at the upper end of the positioning column, and the positioning column is screwed into the threaded head through the threaded hole.

[0014] In order to improve the operation convenience, handles are respectively installed on the left and right sides of the above-mentioned column.

[0015] In order to realize the locking after the boring tool reaches the position, it further includes a plurality of positioning holes provided on the side surface of the turntable, a threaded hole provided at the bottom of the driving rod, and a bolt Ⅰ is screwed into the threaded hole. When the boring tool at the lowest end of the turntable is in a vertical state, the bolt Ⅰ is inserted into the corresponding positioning hole.

[0016] In order to improve the sealing performance, it further includes a cover plate provided on the driving rod. The cover plate is fixed to the upper end of the support through a bolt Ⅱ, and the cover plate closes the upper end of the through hole.

[0017] The beneficial effect of the present utility model is that the positioning mechanism of the entire auxiliary tooling is inserted into the positioning hole of the aircraft cabin. At this time, the support plate is located below the waterproof floor covering that needs to be bored. The turntable is rotated through a pin shaft, so that the boring tool of the corresponding specification rotates to the lower side and is in a vertical state. Then, the driving rod is moved downward through the driving mechanism, and the boring tool can perform boring operation on the waterproof floor covering. At this time, since the positioning mechanism and the boring tool are in a coaxial state, the boring of the waterproof floor covering and the positioning hole of the aircraft cargo hold are accurately positioned, improving the processing efficiency and accuracy and enhancing the working efficiency.
