Research On Mechanical Performance Analysis And Lightweight Design Of Frame Type Fixture

With the rapid rise of information technology,automation and intelligent manufacturing with the core of industrial robot technology,various mechanical equipment manufacturers are upgrading and renovating production lines on a large scale.Many large tooling equipments are put into use,but due to their own quality Large,the company has to use high-power,large-load industrial robots to use it,which ultimately leads to problems such as large production lines,high energy consumption and high equipment costs,and indirectly affects the ecological environment.Therefore,how to use the composite materials with higher specific strength and specific modulus to replace the traditional metal materials for lightweight design and research of automated production equipment has become a common concern of researchers at home and abroad.In this paper,the large frame clamps used in automobile automation production lines are taken as research objects.Based on the mechanical properties of composite laminates,it is proposed to use long glass fiber reinforced thermoplastic composites(hereinafter referred to as composite materials)instead of traditional metal materials for the main frame structure.Carry out lightweight design and research.Firstly,the mechanical properties of the original metal frame structure are analyzed,and the relevant performance parameters such as stress,strain and mode are obtained,which provides performance comparison parameters for the lightweight design and optimization of the subsequent frame structure.Secondly,the structural characteristics and force of the metal frame are combined.Features,fully consider the structural/material coupling effects of composite materials,strictly follow the design requirements,use composite materials to lightly design the frame structure,and use HyperWorks software as a finite element analysis and optimization tool to optimize the concept size and microscopic from the macro level.Layer thickness optimization and layering sequence optimization Three levels of composite frame structure are optimized in multiple stages,and finally a composite frame structure with good mechanical properties and light weight is obtained.By comparing with the performance of the original metal frame structure,on the basis of ensuring the structural strength and rigidity,the lightweight design goal of the frame type fixture is achieved.Finally,the industrial robot matching selection of the lightweight frame clamp is carried out.The results show that the load model of the industrial robot is optimized,which reduces the production cost input of the enterprise and prolongs the service life and maintenance cycle of the production line equipment.
