The invention provides a method and device for solving the disassembly path of product parts. The method comprises the following steps: solving the path of a first solving stage by taking the assembled posture of the parts as the first start posture of the first solving stage to obtain the first end posture of the first solving stage; solving a path of the second solving stage by taking the first end posture as the second start posture of the second solving stage to obtain the second end posture of the second solving stage; solving a path of the third solving stage by taking the second end posture as the third start posture of the third solving stage to obtain the third end posture of the third solving stage; and connecting the first path from the first start posture to the first end posture, the second path from the second start posture to the second end posture, and the third path from the third start posture to the third end posture in an end-to-end mode to obtain a global disassembly path of the parts. Through the invention, the product disassembly path in a complicated environment can be solved.
Description
technical field [0001] The invention relates to the field of mechanical engineering, in particular to a method and device for solving disassembly paths of product components. Background technique [0002] The assembly path solution of product parts is to search for the assembly path of parts with safety as the main index for the purpose of avoiding obstacles or meeting the needs of operations. means. Assembly path solving technology is an important key technology in Design for Assembly (DFA). The feasibility of the assembly path is directly related to the feasibility of the assembly scheme. In the assembly planning process of modern products, assembly path planning has become one of the key steps. [0003] In the assembly of complex products such as airplanes, ships, automobiles, and spacecraft, due to the many parts and complex structures of the product, the planning of its disassembly / assembly path is carried out in a complex environment composed of product parts, fixtur...
