[0029] Compared to manually drilling holes in the web of an aircraft strand using a handheld drill, this application uses a clamping assembly to hold and fix the web of the aircraft strand. By adjusting the position of the X-axis moving part in the second direction, the drill bit of the drilling component can drill holes in the web. By adjusting the position of the Y-axis moving part in the first direction, the drill bit of the drilling component can make multiple holes distributed along the first direction in the web. This results in higher dimensional and positional accuracy of the drilling in the web, which is more conducive to meeting the assembly accuracy requirements of the overlap strip.

Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0039] like Figure 1 As shown in the figure, an aircraft stringer drilling device according to an embodiment of the present invention includes an aircraft stringer 1 comprising a connecting plate 101 and a web plate 102, wherein the web plate 102 is perpendicular to the connecting plate 101 and includes: a clamping assembly 2, a Y-axis moving slide rail 3, and an X-axis moving slide rail 5.

[0040] The clamping assembly 2 is used to clamp the web plate 102, so that the web plate 102 extends along the first direction Y and is positioned on both sides toward the second direction X.

[0041] Y-axis moving slide rail 3 extends along the first direction Y. One end of Y-axis moving slide rail 3 is connected to clamping assembly 2. Y-axis moving component 4, which can move along the first direction Y, is installed on Y-axis moving slide rail 3.

[0042] X-axis moving slide rail 5 extends along the second direction X. One end of X-axis moving slide rail 5 is connected to Y-axis moving component 4. X-axis moving component 6, which can move along the second direction X, is installed on X-axis moving slide rail 5. Drilling component 7 is installed on X-axis moving component 6. Drill bit 701 of drilling component 7 extends along the second direction X. Drill bit 701 is used to drill holes in web plate 102.

[0043] Among them, the first direction Y and the second direction X are perpendicular to each other.

[0044] It should be noted that the clamping assembly 2 clamps the web 102 of the aircraft spanner 1. The web 102 extends along the first direction Y and is positioned with both sides facing the second direction X. When the X-axis moving member 6 moves along the second direction X on the X-axis moving slide rail 5, it can drive the drilling member 7 to move synchronously. The drill bit 701 of the drilling member 7 extends along the second direction X, passing from one side of the web 102 to the other side along the second direction X, thus drilling a hole in the web 102. Afterwards, the X-axis moving member 6 retracts, causing the drill bit 701 to disengage from the web 102. When the Y-axis moving member 4 moves along the first direction Y on the Y-axis moving slide rail 3, it can drive the X-axis moving member 6 and the drilling member 7 to move along the first direction Y, thereby moving the drill bit 701 of the drilling member 7 to the next position in the web 102 that needs to be drilled along the first direction Y, thus drilling multiple holes distributed along the first direction Y in the web 102.

[0045] Compared to manually drilling holes in the web 102 of the aircraft stringer 1 with a handheld drill, this application uses a clamping assembly 2 to clamp and fix the web 102 of the aircraft stringer 1. By adjusting the position of the X-axis moving part 6 in the second direction X, the drill bit 701 of the drilling part 7 can drill holes in the web 102. By adjusting the position of the Y-axis moving part 4 in the first direction Y, the drill bit 701 of the drilling part 7 can drill multiple holes distributed along the first direction Y in the web 102. The form and position accuracy of drilling the web 102 is higher, which is more conducive to meeting the assembly accuracy requirements of the overlapping strip.

[0046] like Figure 1 As shown, in a more specific embodiment, the X-axis moving member 6 is equipped with a Z-axis moving slide rail 8 extending along the third direction Z, and the aircraft stringer drilling device also includes: a Z-axis moving member 9.

[0047] Z-axis moving part 9 is mounted on Z-axis moving slide rail 8 and can move along the third direction Z. Drilling part 7 is mounted on Z-axis moving part 9.

[0048] Among them, the first direction Y, the second direction X, and the third direction Z are perpendicular to each other.

[0049] It should be noted that the Z-axis moving part 9 is mounted on the Z-axis moving slide rail 8 and can move along the third direction Z. The drilling part 7 is mounted on the Z-axis moving part 9. Therefore, when the Z-axis moving part 9 moves along the third direction Z, it can drive the drill bit 701 of the drilling part 7 to move along the third direction Z. Thus, when the drill bit 701 drills a hole in the web 102, it can adjust the height of the hole on the web 102 in the third direction Z, so as to adapt to the assembly of more types of overlapping strips.

[0050] like Figure 1-3 As shown, in a more specific embodiment, it also includes: a Z-axis drive 10;

[0051] Z-axis drive 10 is used to drive Z-axis moving member 9 to move along a third direction Z. Z-axis drive 10 includes Z-axis lead screw 1001 and Z-axis grip 1002. Z-axis lead screw 1001 extends along a third direction Z and passes through X-axis moving member 6 and Z-axis moving member 9. Z-axis grip 1002 is installed at one end of Z-axis lead screw 1001.

[0052] It should be noted that the Z-axis drive component 10 is mounted on the Z-axis sliding rail 8, the Z-axis lead screw 1001 extends along the third direction Z and passes through the X-axis moving component 6 and the Z-axis moving component 9, the Z-axis grip 1002 rotates, causing the Z-axis lead screw 1001 to rotate, the X-axis moving component 6 is fixed in the third direction Z, and the Z-axis moving component 9 can move along the Z-axis lead screw 1001 and the Z-axis sliding rail 8 in the third direction Z without rotating.

[0053] like Figure 1-3 As shown, in a more specific embodiment, the Z-axis moving member 9 includes an adjusting part 901 and a mounting part 902. The adjusting part 901 is disposed on the side of the X-axis moving member 6 in the third direction Z. The Z-axis lead screw 1001 passes through the X-axis moving member 6 and the adjusting part 901. The mounting part 902 is connected to the adjusting part 901 on the side in the first direction Y. The X-axis moving member 6 is mounted with a Z-axis moving slide rail 8 on the side near the mounting part 902. The mounting part 902 is mounted on the Z-axis moving slide rail 8. A drilling part 7 is mounted on the mounting part 902.

[0054] The mounting part 902 has a mounting hole 9021 that extends through the third direction Z. The drilling part 7 is a right-angle drill. The handle 702 of the right-angle drill is inserted into the mounting hole 9021, and the drill bit 701 of the right-angle drill extends along the second direction X.

[0055] It should be noted that the Z-axis moving part 9 includes an adjusting part 901 and a mounting part 902. The adjusting part 901 is located on the side of the X-axis moving part 6 in the third direction Z. The Z-axis lead screw 1001 passes through the X-axis moving part 6 and the adjusting part 901. The mounting part 902 is mounted on the Z-axis moving slide rail 8. The rotating Z-axis gripping part 1002 drives the Z-axis lead screw 1001 to rotate. The position of the X-axis moving part 6 in the third direction Z is fixed. The adjusting part 901 moves along the Z-axis lead screw 1001 in the third direction Z, driving the mounting part 902 to move along the Z-axis moving slide rail 8 in the third direction Z.

[0056] Since the mounting part 902 is located on the same side of the adjusting part 901 and the X-axis moving part 6 in the first direction Y, the handle 702 of the right angle drill can be inserted into the mounting hole 9021 on the mounting part 902, and there is no obstruction in the third direction Z. The drill bit 701 at one end of the right angle drill is outside the mounting hole 9021 and can drill a hole in the web plate 102. The other end of the right angle drill is connected to an electric wire to provide power to the drill bit 701.

[0057] like Figure 1 , 4 As shown, in a more specific embodiment, there are two mounting parts 902, which are respectively connected to the two sides of the adjusting part 901 in the first direction Y. The X-axis moving member 6 is equipped with Z-axis moving slide rails 8 on both sides near the two mounting parts 902, and the mounting parts 902 are mounted on the corresponding Z-axis moving slide rails 8.

[0058] It should be noted that there are two mounting parts 902, which are respectively connected to the two sides of the adjusting part 901 in the first direction Y. The X-axis moving part 6 is equipped with Z-axis moving slide rails 8 on both sides near the two mounting parts 902. The mounting parts 902 are mounted on the corresponding Z-axis moving slide rails 8. Therefore, the rotating Z-axis gripping part 1002 drives the Z-axis lead screw 1001 to rotate. The adjusting part 901 moves along the Z-axis lead screw 1001 in the third direction Z, and the two mounting parts 902 move along the two Z-axis moving slide rails 8 in the third direction Z.

[0059] Both mounting parts 902 are equipped with drilling components 7, that is, the two drilling components 7 are arranged sequentially in the first direction Y. Therefore, when the Z-axis moving component 9 moves along the second direction X, the drill bits 701 of the two drilling components 7 can drill holes in the web plate 102 at the same time, thereby improving the efficiency of drilling multiple holes in the web plate 102 in the first direction Y.

[0060] like Figure 3 As shown, in a more specific embodiment, it also includes: a Y-axis drive 11;

[0061] Y-axis drive 11 is used to drive Y-axis moving member 4 to move along the first direction Y. Y-axis drive 11 includes Y-axis lead screw 1101 and Y-axis gripping part 1102. Y-axis lead screw 1101 extends along the first direction Y and passes through Y-axis moving member 4 and clamping assembly 2. Y-axis gripping part 1102 is installed at one end of Y-axis lead screw 1101.

[0062] It should be noted that the Y-axis moving part 4 is mounted on the Y-axis moving slide rail 3, the Y-axis lead screw 1101 extends along the first direction Y and passes through the Y-axis moving part 4 and the clamping assembly 2, the Y-axis gripping part 1102 rotates, causing the Y-axis lead screw 1101 to rotate, the clamping assembly 2 is fixed in the first direction Y, and the Y-axis moving part 4 can move along the Y-axis lead screw 1101 and the Y-axis moving slide rail 3 in the third direction Z without rotating.

[0063] The Y-axis moving component 4 is mounted on the Y-axis moving slide rail 3, specifically: the Y-axis moving slide rail 3 passes through the Y-axis moving component 4.

[0064] like Figure 4-5 As shown, in a more specific embodiment, it also includes: an X-axis drive 12;

[0065] The X-axis drive 12 is used to drive the X-axis moving member 6 to move along the second direction X. The X-axis drive 12 includes an X-axis lead screw 1201 and an X-axis gripping part 1202. The X-axis lead screw 1201 extends along the second direction X and passes through the X-axis moving member 6 and the Y-axis moving member 4.

[0068] like Figure 5 As shown, in a more specific embodiment, the clamping assembly 2 includes a frame 201, two fixing blocks 202, and two positioning bolts 203:

[0069] Two fixing blocks 202 are installed sequentially at the bottom of the frame 201 along the second direction X. The positioning bolts 203 extend along the second direction X. The two positioning bolts 203 pass through the two fixing blocks 202 respectively, and the two positioning bolts 203 define a clamping opening 204 for clamping the web plate 102.

[0070] One end of the Y-axis moving slide rail 3 is connected to the frame 201.

[0071] It should be noted that the two fixing blocks 202 are installed sequentially at the bottom of the frame 201 along the second direction X, and the positioning bolts 203 extend along the second direction X. The two positioning bolts 203 pass through the two fixing blocks 202 respectively, and the two positioning bolts 203 define a clamping opening 204 for clamping the web plate 102. Thus, adjusting the distance between the two positioning bolts 203 can adjust the size of the clamping opening 204 to accommodate clamping and fixing web plates 102 of different thicknesses.

[0072] The bottom of rack 201 is also equipped with feet.

[0075] Furthermore, two clamping components 2 are connected to both ends of the Y-axis moving slide rail 3 to ensure the stability of the Y-axis moving slide rail 3 as it extends along the first direction Y, and to ensure the stability of the movement of the Y-axis moving component 4.

[0076] When the Y-axis drive unit 11 includes the Y-axis lead screw 1101, the Y-axis lead screw 1101 also passes through the two clamping assemblies 2, improving the stability of the Y-axis lead screw 1101.

When the X-axis moving member 6 moves along the second direction X on the X-axis moving slide rail 5, it can drive the drilling member 7 to move synchronously. The drill bit 701 of the drilling member 7 extends along the second direction X and passes from one side of the web plate 102 to the other side along the second direction X to drill a hole in the web plate 102. Afterwards, the X-axis moving member 6 retracts, causing the drill bit 701 to disengage from the web plate 102.
