In view of the inaccurate statistics of quality information, the accumulation of measurement tasks can not be measured in time, and the traceability of abnormal parts can not be realized in the process of parts inspection in the metering room of a manufacturing enterprise, a measuring room parts measuring system was designed based on B/S architecture. In view of some problems that exist in the process of measuring parts in the measuring room, this system provides solutions through modules. The system uses Java programming language and selects MySQL database for data storage. The front-end measurement system page uses Thymeleaf template engine and the back-end uses SpringBoot framework to realize the business logic. Through the practical application in a manufacturing enterprise, the system can meet the business needs of the enterprise to solve the problems of low efficiency and inaccurate data filling in the measurement process.
Part deformation was one of the main sources of assembly errors. Traditional assembly accuracy analysis usually regarded parts as rigid body without considering the influence of deformation on assembly accuracy. This article took part deformation as the object of analysis. Firstly, the small displacement torsors theory was used to model the deformation of the front and rear mating characteristic surfaces of the part, and the relative pose relationship was used as the deformation of a single part. Secondly, the mapping relationship between part deformation and assembly error was established by the homogeneous coordinate transformation theory. Finally, the influence weight of each part deformation on the assembly error was obtained by sensitivity analysis, and the assembly accuracy was improved by increasing the stiffness of the key part deformation error sources. The calculation method of the key deformation error source is verified by an example analysis.
