Abstract

The invention discloses an assembly unit division method based on assembly relation grading, and the method comprises the steps: 1, obtaining an assembly relation value table of an assembly body, anddetermining a grade relation value between any two functional parts according to the assembly relation of all functional parts and the values; 2, calculating a grade relationship value of each assembly relationship and each functional part according to the grade relationship value of each functional part; 3, determining the sum of the weights of all the assembly relations to the grade relation ofany functional part, and selecting basic parts from all the functional parts from large to small according to the sum of the weights of the grade relation; and 4, dividing the assembly units accordingto the grade relationship values between the basic parts and the non-basic parts. The division method is simple to implement and high in feasibility; the applicability is high, and functional parts of different assembling bodies can be divided into assembling units through the method; conversion of brawling graph structural features is not needed, conversion into computer language is easy, and the automation degree is high.

Description

technical field

[0001] The present application relates to the technical field of assembly unit division, and in particular to an assembly unit division method based on the hierarchical assembly relationship. Background technique

[0002] For an assembly with a large number of parts and a complex assembly process, if the assembly sequence planning is carried out directly, the problem of "combination explosion" will inevitably occur. One of the effective ways to solve this problem is to unitize the complex assembly and divide it into multiple parts. An assembly unit (or sub-assembly) with fewer parts, thus simplifying the assembly sequence planning process of complex products and shortening the efficiency of product development.

[0003] The methods for unitizing complex assemblies in the prior art can be roughly divided into clustering methods, process information division methods, and graph and tree structure theoretical division methods and case-by-case reasoning methods. ...
