Description

High-precision repairing tool for aircraft cabin door

Technical Field

The utility model belongs to aeronautical manufacturing engineering/aircraft assembly field relates to aircraft cabin door high accuracy repairing tool for the straightness accuracy that outer fringe was repaired when guaranteeing aircraft nose landing gear hatch door covering surplus repair, guarantee with organism covering butt joint clearance even, uniformity, improve super long dimension covering repair precision and quality.

Background

The landing gear cabin door is an essential structural component under the requirement of modern aircraft aerodynamic configuration, the cabin door of the existing aircraft nose landing gear is long in size, the change of the external surface curved surface is complex, and in order to eliminate assembly deviation during assembly, process allowance needs to be added on the outer edge of the cabin door skin so as to solve the problem of the occurrence of the condition of the gap tolerance between the fuselage skin and the cabin door skin. The existing cabin door skin allowance repairing is a manual marking repairing process method: when the cabin door of the front landing gear is installed, a process allowance cutting line which is required to be removed at the butt joint of the cabin door skin and the fuselage is marked out, the cabin door is taken down, the wind drilling milling wheel is manually held on the bracket, and the allowance of the cabin door skin is removed by one section at a point according to the cutting line until the outer edge of the repaired skin coincides with the cutting line. The assembling process method is greatly influenced by manual operation deviation, and has the problems of low repairing precision and large straightness deviation of the outer edge of the repaired skin.

Therefore, the existing manual repair process method cannot meet the precision requirement and the detection dominance requirement, and a high-precision repair tool with high precision and small deviation of outer edge repair straightness of the aircraft cabin door needs to be designed to solve the problems.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides an aircraft cabin door high accuracy repairing tool.

The utility model discloses the technical scheme who adopts as follows:

the high-precision repairing tool for the aircraft cabin door comprises a profiling sliding rail 1, an arched support 2, a positioning pointer 3, a pointer sliding block 4, a pneumatic drill clamp holder 5, a clamp holder up-and-down adjusting sliding rail 6, a clamp holder sliding block 7, a pneumatic drill 8 and a cabin door clamp 9.

The two arched supports 2 are clamped on the cabin door and are clamped through a cabin door clamp 9; the pointer sliding block 4 is arranged at the end parts of the two arched supports 2, and the positioning pointer 3 is arranged on the pointer sliding block 4 and used for positioning; two ends of the profiling sliding rail 1 are respectively arranged on the two arched supports 2; the clamp holder slider 7 is installed on the profiling slide rail 1, the clamp holder up-and-down adjusting slide rail 6 is installed on the clamp holder slider 7, the pneumatic drill clamp holder 5 is installed on the clamp holder up-and-down adjusting slide rail 6, the pneumatic drill 8 is installed on the pneumatic drill clamp holder 5, the clamp holder slider 7 slides left and right along the profiling slide rail 1, and the pneumatic drill clamp holder 5 slides up and down on the clamp holder up-and-down adjusting slide rail 6, so that the pneumatic drill 8 is driven to slide left and right up and down.

The utility model has the advantages that: the utility model discloses an aircraft cabin door high accuracy covering surplus is repaiied and is provided an audio-visual, simple and convenient repairment frock, has solved the big problem of covering outer fringe limit straightness accuracy deviation that aircraft cabin door covering surplus is repaiied the precision low, inefficiency, repairment. The utility model discloses a frock is easy and simple to handle, the flexibility ratio is high, the precision is high, and the assembly is simple, feasible, and the product of assembling accords with design, quality index requirement, promotes covering surplus repair precision by a wide margin, improves product assembly quality.

Drawings

Fig. 1 and 2 are front and side views, respectively, of a high-precision repair tool for an aircraft door;

in the figure: the device comprises a profile modeling sliding rail 1, an arched support 2, a positioning pointer 3, a pointer sliding block 4, a pneumatic drill holder 5, a vertical adjusting sliding rail of the holder 6, a holder sliding block 7, a pneumatic drill 8 and a cabin door clamp 9.

Detailed Description

The following further describes a specific embodiment of the present invention with reference to the drawings and technical solutions.

As shown in fig. 1 and fig. 2, the utility model discloses an aircraft cabin door high accuracy repairing tool, adjust slide rail 6, holder slider 7, pneumatic drill 8 and hatch door binding clasp 9 from top to bottom including profiling slide rail 1, bow-shaped support 2, location pointer 3, pointer slider 4, pneumatic drill holder 5, holder. The two arch supports 2 are clamped on the cabin door and are clamped through a cabin door clamp 9; the pointer sliding block 4 is arranged at the end part of the arched support 2, and the positioning pointer 3 is arranged on the pointer sliding block 4 and used for positioning; two ends of the profiling sliding rail 1 are respectively arranged on the two arched supports 2; the clamp holder slider 7 is installed on the profiling slide rail 1, the clamp holder up-and-down adjusting slide rail 6 is installed on the clamp holder slider 7, the pneumatic drill clamp holder 5 is installed on the clamp holder up-and-down adjusting slide rail 6, and the pneumatic drill 8 is installed on the pneumatic drill clamp holder 5.

The utility model discloses a high accuracy repairing tool replaces the assembly method that the operator repaired according to the marking off manual work, and concrete use step is as follows:

1) Installing a front landing gear cabin door on the airplane, and marking out a cabin door skin allowance line;

2) Moving the pointer slide block 4 to enable the tip ends of the front and rear positioning pointers 3 to be aligned with two ends of a repairing line, aligning a margin line positioning tool by taking the positioning pointer 3 on the tool as a reference, and positioning a tool repairing track; a cabin door clamp 9 on the arched support 2 is used for clamping the cabin door, so that the relative position of the tool and the cabin door is fixed;

3) Mounting the pneumatic drill 8 on the pneumatic drill holder 5;

4) The position of the pneumatic drill 8 is adjusted up and down on the clamp holder up and down adjusting slide rail 6 to reach an effective cutting position; the gripper sliding block 7 moves on the profiling sliding rail 1, so that the covering allowance of the cabin door is cut step by step, the cutting amount of the allowance is checked, the final design requirement is met, and the covering allowance repairing is completed.

After the tool is adopted, the deviation fluctuation of the air drill relative to the repairing position line when the aircraft cabin door skin allowance is cut is limited, the assembly precision is greatly improved, the cabin door repairing work is simpler and more convenient, no mistake is made, and the problems of low repairing precision of the aircraft cabin door skin allowance, low efficiency and large straightness deviation of the repaired skin outer edge are effectively solved.
