[0038] The invention provides a docking hole positioning device and a docking hole positioning method for fuselage docking, which can quickly position a plurality of docking holes and have good positioning accuracy, low labor intensity for workers and high efficiency.

[0039] like Figure 1-3As shown, the docking hole positioning device for fuselage docking is used to position the processing positions of multiple docking holes to be processed in the fuselage docking area. The docking hole positioning device for fuselage docking includes a positioning template component, a hole making template component and a plurality of positioning pins 3.

The two first positioning holes 13 on the positioning template 1 The corresponding position on the fuselage is the processing position of the second positioning hole, and the second positioning hole is processed at the processing position of the second hole. Multiple positioning templates 1 are arranged along the circumference of the fuselage to process multiple second positioning holes distributed along the circumference of the fuselage; the hole-making template assembly includes multiple hole-making templates 2, and the multiple hole-making templates 2 are detachably connected head to tail and form a ring, which is sleeved on the outside of the fuselage. The hole-making template 2 is provided with multiple third positioning holes 21 at intervals, wherein a part of the multiple third positioning holes 21 corresponds to the second positioning hole one by one, and the other part corresponds to the position of the docking hole to be processed one by one. The positioning pin 3 is inserted into the second positioning hole and the third positioning hole 21 corresponding to the second positioning hole to fix the relative position of the hole-making template 2 and the fuselage, and the positions of the multiple docking holes can be determined according to the positions of the remaining third positioning holes 21.

[0040] The docking hole positioning device for fuselage docking first uses two first positioning holes 13 on the positioning template 1 to determine the processing position of the second positioning hole on the fuselage and processes the second positioning hole on the fuselage, and then uses the positioning pin 3 to plug the second positioning hole and the third positioning hole 21 on the hole making template 2 to fix the hole making template 2 to the fuselage. The distribution positions of the multiple third positioning holes 21 on the hole making template 2 are the same as the distribution positions of the multiple docking holes to be processed on the fuselage. After the hole making template 2 is fixed to the fuselage, the processing positions of the multiple docking holes on the fuselage can be determined according to the multiple third positioning holes 21 on the hole making template 2. The docking hole positioning device for fuselage docking has a simple structure and is easy to operate. It can reduce the labor intensity of the staff, improve the hole making efficiency of the docking area, and accurately locate the position of the docking hole.
