Background
Along with the continuous increase of the national degree of vision of aviation technology, the new machine development task enters a period of various machine types and short design and manufacturing period; particularly, products corresponding to the movable airfoil surface type assembly fixture are various in types and sizes, for example: the inner flap, the outer flap, the aileron, the elevator, the rudder and the like are also required to meet some special requirements of an automatic hole making production line on the assembly tool, for example, the tool needs to be movable, the positioning support leg needs to meet the ground cone head spacing of the production line, and the like, so that the design and manufacturing time of the movable airfoil assembly tool is very long, the development of a new machine is seriously restricted, and meanwhile, the disposable probability of a large number of test piece assembly tools brought by the development of the new machine is very high, so that the development cost of the scrapped test piece tool is greatly increased, and therefore, how to shorten the design and manufacturing period and reduce the development cost becomes the main research direction and the research difficulty of the movable airfoil assembly tool.
At present, the assembly tools of movable wing surfaces of domestic large-scale army and civil aircraft are all designed in a mode that a product corresponds to an assembly tool, and tool designers generally experience from receiving a product model to finishing tool design tasks: the product is analyzed, the tool main body is primarily designed, the tool main body structure is optimized and changed according to the positioner, the tool positioner structure is thinned, the design of the whole assembly tool is finally completed, and the assembly tool for the disposable test piece can be used along with the extremely individual positioner components, and most of other tool main bodies are scrapped, so that the following defects are caused:
(1) the design period is long: because each product corresponds to a tool main body, a designer needs to spend a great deal of time to think about the main body structure design, repeatedly modify and optimize the main body structure, and the later-stage drawing workload is added, so that the time cost is more than half of the whole tool design.
(2) The manufacturing period is long: the manufacturing unit can prepare materials when the tool design is finished and the tool main body is primarily designed, then the machining and the manufacturing can be performed after the tool is completely designed, wherein the waiting time is too long, meanwhile, the tool main body forms are different, the manufacturing unit process staff needs to spend a great deal of time to compile a machining process route, an assembly process route and a numerical control machining program, and the operation staff needs to carefully study the drawing and the process list to perform the machining and the manufacturing, so that the time consumption is huge.
(3) The development cost is high: because a large number of test piece assembly tools are generated at the beginning of a new grinding machine type, most of the tools are disposable due to the later product change, and most of the tool main bodies can be scrapped and wasted greatly except for a few positioning components.
