Aircraft assembly is throughout the aircraft manufacturing process, however assembly-type mounts play a crucial role in aircraft assembly. The advanced airplane assembly fixture can improve the assembly working efficiency, shorten the manufacturing period, reduce the rework rate and improve the assembly quality. At present, the assembly of domestic airplanes largely adopts manual positioning or semi-automatic positioning, and mainly adopts manual operation. Because the rigidity of the assembly part is small, in order to ensure the geometric dimension and the appearance of the part, a large number of clamps and assembly fixture are needed during assembly, so that the parts can be assembled quickly, efficiently and at low cost.
A large number of guide rail positioning devices are used for positioning in an airplane assembly jig, and the traditional guide rail mounting method is that a worker measures the deviation between the actual position and the theoretical position of a guide rail through a laser tracker, and a wooden hammer is used for knocking the guide rail to adjust the position until the mounting position of the guide rail is adjusted to be within the error range of the theoretical position. Firstly, the guide rail is generally purchased as a component, only a bolt connection mode is adopted for fixing during installation, a certain gap exists between a bolt and an installation hole of the guide rail, the guide rail cannot be positioned by the aid of a cylindrical pin after being fixed, the guide rail can be moved to a certain extent after being used for a period of time, and the positioning requirement of the guide rail cannot be ensured, so that the position of the guide rail is required to be checked and adjusted again after being used for a period of time; secondly, as the assembly precision of the laser tracker is generally within the range of +/-0.1 mm, the laser tracker cannot be used for mounting some slide rails with the mounting precision higher than +/-0.1 mm; finally, when the guide rails are installed by adopting the laser tracker, the requirements of the parallelism among the guide rails on the proficiency and the assembly skill of workers are high, and the labor intensity of the workers and the assembly time of the fixture are increased.
In conclusion: how to design a guide rail mounting tool with simple processing, convenient installation, high precision, high stability, easy adjustment, convenient maintenance and lower cost to improve the assembly quality of the fixture is a technical problem to be solved urgently by technical personnel in the field.
