The Research On The Body Manufacturing Quality Optimization Of Bq Motor In Dimensional Engineering

The main research content of this paper is to introduce the relevant theory of Dimension engineering into quality control work,to assist in the development of white body process quality and early quality prevention work,quality control and size engineering are complementary.Through the integration of the two advantages of resources,effective information to each other to achieve the gradual improvement of the quality of the body and shorten the body design and development cycle of the target.In the real manufacturing process,quality control runs through the whole process of automobile manufacturing,body quality problems are mainly reflected in the welding quality,dimensional quality and surface Quality.Accuracy quality directly affect the vehicle matching effect,the appearance of the car,the use of performance plays a vital role.Dimension engineering can be used to carry out the concept of body mass and improve the quality of early prevention to solve such problems.Dimensional engineering is a link between product design,process production and quality control,it covers the whole process of car design,craftsmanship and production.It is the basis of body technology planning,quality improvement and production process size control.We can use the dimension chain method to check whether the actual size of the site meets the design requirements.Calculate the component size tolerance required to meet the design requirements and determine the component dimension tolerance,improve content to drive accuracy improvement process,pointing out the need to focus on control of the region,to provide scientific and reasonable data support for the design,process,size,process control.Optimize the size of components,structure and process equipment through the design phase,to carry out early quality prevention work,it has very high effectiveness and traceability.To solve these problems,the idea of dimension engineering can be used to carry out the quality improvement work,and mainly control the most influential part from design,craft,tolerance management and process control,provide data support and scientific and rational basis for process production and quality control,then guide the design and development process of car body.The main work of the article is as follows:(1)combining with various theories of design,craft and manufacturing process,it comes up with the systematic framework of using the dimension engineering theory into quality control process;(2)based on the current BQ car white body moving parts matching problem as an example,elaborate its analysis process,and the improve process of its size tolerance;(3)it comes up with the detailed method and content to guide the product design and craft planning process using dimension engineering theory,in order to have early preventative effect on body quality problems.
