Generally, the airframe of aircraft is very complex and is often divided into several structural elements and assembled. Typically, it can be divided into wing, fuselage, tail wing, engine mount and landing gear.

In particular, the fuselage of an aircraft is divided into a front fuselage, a central fuselage, and a rear fuselage, and then aligned and interconnected.

1 is a cross-sectional view showing a connection state of a front body and a center body of an aircraft.

Referring to FIG. 1, a bulkhead 30 may be coupled to the rear end of the front body 10 to connect the front body 10 and the center body 20 of the aircraft. Air inlet ports 11 and 21 may be coupled to the inside of the front body 10 and the center body 20, respectively. The bulkhead 30 may be provided with a communication portion 31 for allowing the air inlet 11 of the front body 10 and the air inlet 21 of the central body 20 to communicate with each other.

Therefore, during the process of connecting the front body 10 and the center body 20, in order to connect the air inlet 11 of the front body 10 and the air inlet 21 of the center body 20, And the air intake port 21 of the central body 20 to the communication portion 31 of the bulkhead 30. [

For this purpose, the air inlets 11 and 21 may be formed with holes 11a and 21a for engagement with the communicating portion 31 of the bulkhead 30 and the air inlet 11 of the front body 10, And the air intake port 21 of the central body 20 are connected to each other by connecting the front body 10 and the center body 20 and then connecting the holes 11a and 21a formed in the air inlets 11 and 21, A reamer operation for drilling the holes 11a and 21a to expand the holes 11a and 21a and a riveting operation for fastening the air inlets 11 and 21 and the communicating portion 31 of the bulkhead 30 .

The reaming operation and the riveting operation are performed manually by the operator entering the air inlet 11 of the front body 10.

However, since the internal space of the air inlet 11 is narrow and the air inlet 11 is curved, it is difficult for the operator to approach the working position, causing musculoskeletal disorders of the operator, There is a problem that it is exposed to frequent safety accidents.

In addition, since the reaming operation and the riveting operation as described above are performed manually, there is a problem that the process efficiency is lowered.

At this time, the driving unit 140 operates the articulated robot arm 143 to prevent the end effector 150 from colliding with the inner surface of the air inlet 11 of the front body 10.

Subsequently, the vision sensor 153 senses the holes 11a and 21a formed in the connection portion between the communication portion 31 and the air inlets 11 and 21 by the bulkhead 30. [

Subsequently, the optical sensor 155 emits a plurality of lights to the periphery of the holes 11a and 21a, detects light reflected from the surfaces of the air inlets 11 and 21, The distance of the drill 151a, and the angle of the drill 151a with respect to the holes 11a and 21a. The drive unit 140 drives the end effector 150 based on the distance of the drill 151a to the holes 11a and 21a thus detected and the angle of the drill 151a with respect to the holes 11a and 21a The position of the drill 151a relative to the holes 11a and 21a can be precisely aligned.

Subsequently, the drill 151a is rotated by the rotary motor 151, and the drill 151a is advanced toward the holes 11a, 21a so that the holes 11a, 21a are expanded. The chip generated at this time is removed by the chip blower 157, and the oil mist is supplied to the work site by the oil mist supply module 159.

When the left air intake ports 11 and 21 and the left communication portion 31 of the bulkhead 30 are machined to the holes, the main body transfer bogie 120 transfers the main body 110 to the left base block 130, The hole machining apparatus 100 for connecting an aircraft fuselage according to the present embodiment has holes 11a and 21a for the right communicating portion 31 of the bulkhead 30 and right air inlets 11 and 21, Can be processed.

The hole machining of the right air inlets 11 and 21 and the right communicating portion 31 of the bulkhead 30 is performed by the above described left air inlets 11 and 21 and the left communicating portion 31 of the bulkhead 30 Therefore, a description thereof will be omitted.

The left and right air inlets 11 and 21 and the left and right communicating portions 31 of the bulkhead 30 are provided with a pair of left and right air inlet ports 11 and 21, Hole machining can be performed simultaneously.

As described above, the hole machining apparatus 100 for connecting an aircraft fuselage according to the present embodiment includes a front body 10 and a front body 10, which are connected to a bulkhead 30 for connection between the front body 10 and the center body 20 of the aircraft. It is possible to automate hole machining for connecting the air intake port 11 coupled to the center body 20 and the air intake port 21 coupled to the center body 20.

Accordingly, the hole machining apparatus 100 for connecting the aircraft body according to the present embodiment can prevent a safety accident of an operator by manual operation, and can improve the process efficiency.

The embodiments of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms.
