Deformation Analysis And Optimal Design Of The Main Shaft Device Of A Novel Carton Packaging Machine

In the packaging industry,the demand for carton packaging is strong,and the processing quality requirements become more and more high.As a new show in the carton packaging industry cardboard carton packaging,occupies the mainstream market packaging materials for 3C products.In the production process of carton box,the manufacturing speed can not reach the needs of production demand,the new facturing precision is not reach the requirements of technology effect,which is the maket demend.There for,research on a carton production equipment with high precision and high speed,has very important practical significance for the production of cardboard carton.Focused on the low positioning accuracy of the mian shaft device of the new carton packaging machine,this paper analyied this problem and mand several optimization,and made several optimization,and put forward the high shaft device.1.Analyzing the structural characteristics of the main shaft device supporting body,using Ansys Workbench software to calculate its deformation,find the root cause affecting its positioning accuracy.Based on the optimum design theory,the response surface optimization and topological structure optimization of Ansys Workbench finite element Analysis software plate is analyzed and optimized design scheme is proposed.2.Analyzing the structure characteristics of the spindle lifting and clamping components,using Ansys Workbench software to calculate the deformation,find the root cause of the lack of positioning accuracy.Based on the principle of rigidity lifting and the selection of material characteristics,three optimum design points can be raised for the stiffness of mechanical design.The optimization results of three design points are analyzed,and the design requirements are met by finite element analysis.3.Analyzing the working state of the steel ball linear guideway pairs in the spindle device,and extracting a load model of the steel ball linear guideway with the lateral load and preload,and the corresponding mechanical model.The calculation and step of the analytic method for solving the deformation of the steel ball linear guideway are deduced theoretically and the deformation quantity is calculated.The accuracy of the theoretical model is verified by Ansys Workbench FEM,which shows that the model can describe the deformation state of steel ball linear guideway pairs.4.According to the structure characteristics of the spindle lifting and clamping components,analyze the reason of fixture deflection after make linear ball guide deformation by lateral load.The fixture positioning precison values and characteristics were solved by researching deformation of linear ball guide on upright and horizontal direction.The accuracy shortage of carton short direction were determined by solution,and the optimization scheme was proposed according to the solution.This paper mainly introduces the main shaft device of the new carton packaging machine,the mechanical analysis and structural optimization are carried respectively of the main shaft support body,the spindle lifting clamping unit and the steel ball linear guideway,Then the structure of the main spindle device of the new carton packaging machine is improved,and it is used in the production to achieve a good effect.
