[Abstract]:In the packaging industry, the demand for carton packaging is high, and the quality requirements are becoming higher and higher. Cardboard carton packaging, as a new show in carton packaging industry, occupies the mainstream market of 3C products. In the production of carton, the speed of manual carton making is not enough, the production demand of enterprise is not reached, the precision of mechanical carton making is insufficient, and the technological effect required by market is not reached. Therefore, it is of great practical significance to develop a fast and high precision carton production equipment for paperboard carton production. This thesis mainly analyzes the problem of the insufficient positioning accuracy of the spindle device of the new carton packaging machine, and puts forward the optimization design in three aspects, and completes a set of spindle device with high box making precision. This paper analyzes the structural characteristics of the mainstay of the main shaft device, calculates its deformation by using Ansys Workbench software, and finds out the reasons that affect its positioning accuracy. Based on the theory of optimization design, the response surface optimization and topology optimization of ANSYS Workbench finite element analysis software are used to analyze the main support body of the main shaft device, and the optimal design scheme. 2. This paper analyzes the structural characteristics of the main shaft lifting clamping parts, calculates its deformation by using Ansys Workbench software, and finds out the fundamental reasons that affect the positioning accuracy of the parts. Based on the stiffness lifting principle of mechanical design and the characteristic selection of materials, three optimization design points are proposed to enhance the stiffness of mechanical design. The optimization results of the three design points are analyzed by finite element method to meet the design requirements. 3. 3. Based on the analysis of the working state of the steel ball linear guideway pair in the main shaft device, a load model and the corresponding mechanical model of the steel ball linear guide rail pair subjected to lateral load and pretightening force are extracted. The calculation and procedure of calculating the deformation of the steel ball linear guide rail pair are presented in this paper, and the deformation amount is calculated. The accuracy of the theoretical model is verified by using the Ansys Workbench finite element method, which shows that the theoretical model can describe the deformation state of the steel ball linear guideway pair. According to the positioning characteristics of the fixture in the main shaft lifting clamping parts, the mechanism of the jig deflection caused by the deformation of the steel ball linear guide rail pair under lateral load is analyzed. Through the vertical and horizontal deformation of the steel ball straight-line guide rail, the positioning accuracy and characteristics of the fixture are solved. It is determined that the positioning accuracy of the short edge direction of the carton is insufficient, and the optimization scheme is put forward. Based on the introduction of the main shaft device of the new carton packaging machine, the mechanical analysis and structural optimization of the main body of the main shaft device, the main lifting and clamping parts of the spindle and the steel ball linear guide rail pair are carried out respectively in this paper. The structure of the spindle unit of the new carton packaging machine is improved and the practical application of the new type carton packaging machine has achieved good results.
