In modern aircraft assembly and manufacturing processes, the aircraft skin is a member that is wrapped around the aircraft skeleton structure and secured to the skeleton with an adhesive or rivet to form the aerodynamic profile of the aircraft. The skin structure formed by the aircraft skin and the framework has larger bearing capacity and rigidity, and the self weight is very light, so that the aircraft skin and the framework play a role in bearing and transmitting pneumatic load. The skin is under aerodynamic action and then transmits acting force to the connected frame of the fuselage, the stress is complex, and the accuracy of the internal positioning of the skin directly influences the strength of the skin, so that the primary purpose in the production process is that the position meets the drawing requirement.
At present, parts such as a positioning skin, a firewall and a wallboard in a production workshop are roughly divided into three cases, wherein the first case is to position by means of other parts, and the position is determined according to other parts positioned according to a tool or a scribing line. The second case is that the structural space is open, and the positioning can be performed according to the positioner on the tool. The third condition is that the structural space is not open, the appearance of the part is complex, and the part cannot be positioned according to the first two methods, for example, some internal structural parts such as a firewall cannot be positioned through a positioning hole and a special tool due to complex coordination relationship and space limitation, and the positioning is needed manually, so that an operator measures a plurality of relatively accurate dimensions on the frame part as a reference according to the drawing requirements in general, and the position accuracy of the subsequent skin installation is mainly ensured. However, the method has obvious defects, firstly, the manual positioning error is larger only, the manual positioning can influence the position of the part in the normal direction (Z direction), the normal positioning quality directly influences the aerodynamic profile step difference of the subsequent skin, and the situation that the hole positions of each aircraft are different can be caused.

Thirdly, manual positioning needs repeated trial assembly, and production efficiency is reduced. The utility model mainly aims at the third situation, and has important significance in the aspect of positioning firewall parts.
