Study On The Application Of Flexible Fixture In Passenger Bus Manufacturing

Objective:In the modern manufacturing process,flexible toolingis an important means to control the cost of manufacturing process.Especially in passenger car production process,due to the affected by the order of production,models,and other components structure,small batch,change orders easily increase production costs for each module of tooling,emergence of a flexible tooling,in a certain extent reduce the passenger making process technics equipment cost,improve production efficiency and reduce tool change frequency,can also make design personnel reduction in tooling development workload.With our country manufacturing industry development and market demand changes,the research of craft equipment equipped with flexible technology and development model of flexible fixture is very necessary and in the bus manufacturing increased flexible fixture is more important.This paper mainly for flexible fixture in the passenger car production in the process of use and different orders under flexible tooling application research.First of all,this paper analyzes the flexible fixture the basic composition and working principle,and expounds the development of flexible fixture now welding,and traditional fixture for comparison,the creation of products from the bus type,structure,order of,divided various skeleton structure of fixture types.At the same time,the analysis bus industry and trade all structure.Then,according to the structure characteristics of passenger car frame,at the beginning of the product design or orders in the process of structure analysis,and according to the structure tooling design experience,using three-dimensional design software analysis between various kinds of tooling and skeleton matching structure,because of the small quantity and many kinds of orders caused by the tooling are different,high cost,low construction efficiency problems.Finally,tooling and skeleton structure analysis,based on their own tooling design production capacity,create a suitable for their own flexible tooling fixture structure,and apply it in practice,at the same time,in the future intelligent manufacturing in the prospect of the flexible technology development direction.
