In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0051] The present invention provides a drilling jig, a drilling system and a drilling method. During the process of aircraft assembly, the drilling jig, the drilling system and the drilling method provided by the present invention are used to improve the efficiency of drilling and facilitate the operation of workers.

[0052] like Figure 1 As shown, the drilling system provided by the specific embodiment of the present invention includes a drilling jig and a drilling device 4. The drilling jig is provided with a guide hole. During the processing of the workpiece 3, the drilling system needs to fix the drilling device 4 to the drilling jig, and the workpiece 3 is processed through the position of the preset hole on the drilling jig.

[0053] like Figure 1-3As shown, the drilling template includes a first drilling template 1 and a second drilling template 2. The first drilling template 1 is provided with a first guide hole 11 and a through-hole 12. The first guide hole 11 is used to connect with the workpiece 3 and for the tool head of the drilling device 4 to pass through. The second drilling template 2 is detachably connected to the first drilling template 1. The second drilling template 2 is provided with a second guide hole 21. The distribution position of the second guide hole 21 corresponds to the through-hole 12. The second guide hole 21 is used for the tool head of the drilling device 4 to pass through. Specifically, when the holes to be processed on the workpiece 3 are too dense, on the premise of meeting the processing requirements of the holes on the workpiece 3, the aperture of the through-hole 12 is smaller than the aperture of the first guide hole 11, so as to avoid interference between the through-hole 12 and the first guide hole 11. The positions and numbers of the first guide hole 11, the second guide hole 21 and the through-hole 12 are all adapted to the positions and numbers of the holes to be processed on the workpiece 3. The diameter of the through-hole 12 is larger than the diameter of the hole to be processed, so that the through-hole 12 can pass the tool head of the drilling device 4 without affecting the size of the hole to be processed on the workpiece 3.

[0054] The first drilling template 1 is connected to the workpiece 3, and the second drilling template 2 is connected to the first drilling template 1. The workpiece 3 is processed according to the positions of the second guide hole 21 and the through-hole 12, and then the second drilling template 2 is disassembled, and the drilling device 4 is connected to the first drilling template 1. The workpiece 3 is processed according to the position of the first guide hole 11 preset on the first drilling template 1. Finally, the connection position of the workpiece 3 and the first drilling template 1 is changed, and the unprocessed holes on the workpiece 3 are processed, thereby completing the processing of all the holes on the workpiece 3. During the entire processing process, there is no need to install or disassemble the workpiece 3 on the second drilling template 2. The workpiece 3 is always connected to the first drilling template 1, which reduces the number of times the workpiece 3 is disassembled and assembled, and the processed hole position is not prone to deviation, thereby improving the processing accuracy of the holes on the workpiece 3.

[0055] like Figure 4-5 As shown, during the processing of the workpiece 3 , the workpiece 3 needs to be connected to the first drilling template 1 . The first drilling template 1 and the workpiece 3 are connected via a connecting assembly, which includes a first connecting member 5 and a second connecting member 6 .

[0056] In order to ensure that the first connecting member 5 does not loosen, that is, to ensure the stability of the connection between the first drilling template 1 and the workpiece 3, the first guide hole 11 is a tapered hole, and the aperture of the upper end of the first guide hole 11 along the penetration direction of the drilling device 4 is larger than the aperture of the lower end of the first guide hole 11; the first connecting member 5 is placed in the first guide hole 11, and the first connecting member 5 includes a side wall 51 and a bottom surface 52, and the bottom surface 52 of the first connecting member 5 is provided with an opening for the rod portion of the second connecting member 6 to penetrate, and the shape of the side wall 51 of the first connecting member 5 matches the shape of the hole wall of the first guide hole 11, and the head of the second connecting member 6 abuts against the bottom surface 52 of the first connecting member 5. The first connecting member 5 is used to fix the second connecting member 6. The first guide hole 11 is a tapered hole that is wide at the top and narrow at the bottom, so that the first connecting member 5 cannot move downward after being placed in the first guide hole 11, and plays a role in fixing the first connecting member 5. The head of the second connecting member 6 abuts against the bottom surface 52 of the first connecting member 5 to avoid the head of the second connecting member 6 being exposed to the first drilling template 1, resulting in interference between the second connecting member 6 and the drilling device 4 provided at the first guide hole 11 or the through-hole 12. Specifically, in this embodiment, the second connecting member 6 is a connecting bolt 61, and is equipped with a connecting nut 62 to lock and fix the second connecting member 6.

[0057] like Figure 1-3 As shown, during the processing of the workpiece 3, the second drilling template 2 needs to be connected to the first drilling template 1. The first drilling template 1 is provided with a first connection hole 91, and the second drilling template 2 is provided with a second connection hole 92. The first connection hole 91 and the second connection hole 92 are used to detachably connect the first drilling template 1 and the second drilling template 2. In this embodiment, the first connection holes 91 are respectively opened at the four corners of the first drilling template 1, and the second connection holes 92 are respectively opened at the four corners of the second drilling template 2, so that the connection between the first drilling template 1 and the second drilling template 2 is more stable. Specifically, the first connection holes 91 and the second connection holes 92 are penetrated by bolts to realize the connection between the first drilling template 1 and the second drilling template 2, and are locked and fixed by nuts.

[0058] like Figure 1-3 and Figure 6 As shown, during the process of machining the workpiece 3 , the drilling device 4 needs to be connected to the first drilling template 1 (not shown in the figure) or the drilling device 4 needs to be connected to the second drilling template 2 .

[0059] In order to connect the drilling device 4 with the first drilling template 1 or the second drilling template 2, the outer peripheral sides of the first guide hole 11 and the second guide hole 21 are provided with a clamping groove 7, and the clamping groove 7 is used to clamp the drilling device 4. Adaptively, the drilling device 4 includes a fixing member 42 and a drill 41, one end of the fixing member 42 is connected to the drill 41, and the other end of the fixing member 42 is provided with a clamping member 421, and the clamping member 421 is used to clamp with the clamping groove 7 on the first drilling template 1 or the second drilling template 2.

[0060] Furthermore, in order to allow the cutter head of the drill 41 to smoothly penetrate and act on the workpiece 3, the fixing member 42 has a channel along its axial direction, and the end of the fixing member 42 connected to the first drilling template 1 or the second drilling template 2 is provided with a cutter end 422, and the cutter end 422 can penetrate the first guide hole 11 or the second guide hole 21 and have a clearance fit with the first guide hole 11 or the second guide hole 21, and the cutter end 422 has a through hole at one end of which is connected to the channel, and the channel and the through hole are provided for the cutter head of the drill 41 to penetrate.

[0061] Specifically, in this embodiment, one end of the fixing member 42 connected to the knife end 422 is a round head, and the other end is a square head. The square head end of the fixing member 42 is connected to the drill 41, and the knife end 422 is loosely matched with the first guide hole 11 or the second guide hole 21. The clamping member 421 is a combination of a cylindrical head and a cylindrical rod. Accordingly, the clamping groove 7 includes a circular hole for the cylindrical head of the clamping member 421 to pass through and a slide rail for clamping the cylindrical head and sliding the cylindrical rod. The clamping groove 7 is an arc groove arranged around the axis direction of the first guide hole 11 or the second guide hole 21, and two clamping grooves 7 are arranged along the circumference of each of the first guide hole 11 and the second guide hole 21. The two clamping grooves 7 are arranged with the center of the circle of the first guide hole 11 or the second guide hole 21 as the symmetry center, and are arranged in a central symmetric manner, so that the clamping is more stable. The clamping groove 7 is arranged in an arc shape so that the clamping groove 7 can match the shape of the first guide hole 11 and the second guide hole 21. When clamping, the cutting end 422 of the fixing piece 42 is passed through the first guide hole 11 or the second guide hole 21, the cylindrical head of the clamping piece 421 is aligned with the hole on the clamping groove 7, the cylindrical head of the fixing piece 42 is pushed into the circular hole of the clamping groove 7 and rotated along the arc direction of the clamping groove 7, and the fixing piece 42 is tightened and fixed to the first drilling template 1 or the second drilling template 2 by rotating and sliding the clamping piece 421 in the clamping groove 7.

[0062] Furthermore, if Figure 1-3 and Figure 7 As shown, in order to remove the waste chips after processing and make the processing process smoother, the first drilling template 1 and the second drilling template 2 are respectively provided with a chip removal groove 8 on the side opposite to the connecting drilling device 4, and the chip removal groove 8 passes through the end surface of the first drilling template 1 or the second drilling template 2. Specifically, in this embodiment, the chip removal groove 8 is configured as a plurality of interconnected grooves distributed horizontally or vertically along the first drilling template 1 or the second drilling template 2, which is conducive to the formation of airflow and ensures smooth chip removal.

[0063] like Figure 8 As shown, in other embodiments, there is no limitation on the size specifications of the first drilling template 1 and the second drilling template 2. Two or more first drilling templates 1 and one or more second drilling templates 2 can also be used in combination and connected to the workpiece 3 for drilling holes in the workpiece 3.
