Embodiment 1

[0020] Referring to Figures 1-3, it is a schematic structural view of Embodiment 1 of the present invention, an aircraft skin grinding device, including a positioning frame 1, a carriage 2, a sliding beam 3, two pairs of vacuum suction cups 4, a first electronic slide rail 5, A pair of second electronic slide rails 6, a servo motor 7, a turntable 8, a grinding motor 9 and a grinding wheel 10, the positioning frame 1 and the sliding frame 2 are rectangular frames, and two pairs of the vacuum suction cups 4 are detachably connected to the positioning frame 1 at the four corners of the lower surface, the upper and lower sides of the lower surface of the carriage 2 are horizontally slidably connected to the positioning frame 1, and the first electronic slide rail 5 is arranged in one of the sliding connections between the carriage 2 and the positioning frame 1, And the connecting surface of the first electronic slide rail 5 is detachably connected with the positioning frame 1, the ...

Embodiment 2

[0023] refer to Figure 2-3 Compared with Embodiment 1, this embodiment is different in that it also includes a connecting rod 11, one end of which is detachably connected to the four corners of the lower surface of the positioning frame 1, and the other end of the connecting rod 11 is detachably connected Vacuum suction cup4.

[0024] In actual use: when the damaged part of the aircraft skin is a hyperbolic skin, the suction position of the vacuum suction cup 4 can be changed through the connecting rod 11, so that the positioning frame 1 can be stably positioned on the aircraft skin.

Embodiment 3

[0026] Referring to Figure 1 and image 3 Compared with Embodiment 1 or 2, the difference of this embodiment is that: the positioning frame 1 is detachably connected with a recovery bucket 12, the recovery bucket 12 has an opening, and a recovery bag 13 is connected under the opening .

[0027] In actual use: there will be debris when the skin is polished, and the splashed debris can be collected through the recovery bucket 12, and the debris falls into the recovery bucket 12 and enters the recovery bag 13 below to complete unified recovery.

Abstract

The invention relates to the field of aircraft skin grinding, in particular to an aircraft skin grinding device. The aircraft skin grinding device comprises a positioning frame, a sliding frame, a sliding beam, two pairs of vacuum suction cups, a first electronic sliding rail, a pair of second electronic sliding rails, a servo motor, a rotating frame, a grinding motor and a grinding wheel. The positioning frame and the sliding frame are rectangular frames. The two pairs of vacuum suction cups are detachably connected to the four corners of the lower surface of the positioning frame. The upperand lower sides of the lower surface of the sliding frame are transversely and slidably connected to the positioning frame. The first electronic sliding rail is arranged inside one sliding connectionof the sliding frame and the positioning frame, and the connection face of the first electronic sliding rail is detachably connected with the positioning frame. The sliding end of the first electronicsliding rail is detachably connected with the lower surface of the sliding frame. Due to the fact that the positioning frame is sucked to the surface of an aircraft by adopting the vacuum suction cups, the problem that operation can only be performed on a maintenance workshop workbench is effectively solved, and operation is not limited by maintenance conditions. The rotating angle of the grinding motor is controlled by adopting the servo motor, and therefore the grinding depth can be accurately controlled.

Description

technical field [0001] The invention relates to the field of aircraft skin grinding, in particular to an aircraft skin grinding device. Background technique [0002] Aircraft skin damage caused by lightning strikes, stone impacts, and bird strikes occurs frequently during aircraft flight. Direct replacement of aircraft skin materials and time costs are too high, which seriously restricts the development of the civil aviation industry. In the existing technology, manual grinding is used for grinding and repairing. This maintenance method and the technology of the postgraduate staff, if there is too much grinding and missing repairs, it will seriously affect the safety of the aircraft flight, and the grinding accuracy is low, which seriously reduces The repair rate of aircraft skin requires a more precise grinding method. Contents of the invention [0003] The invention provides an aircraft skin grinding device, which solves the problem of low precision of traditional grind...
