| TB tire automatic trimming machine in tire production line can be received on the tire to achieve full automation,remove the tread and sidewall of the tire out of lanugo,and save a lot of manpower,material resources,can significantly improve the tire production efficiency,product quality,has very broad prospects for development.Through consulting a large number of data the appearance of the finished tire,existing problems,understand the current development level of the machine tire surface treatment,finally summed up the current market presence of similar product information,put forward the automatic tire repair problems and gives the existence of the edge of the thought and content of this paper.The control system of automatic trimming assembly and repair this paper focuses on the research of the tire edge machine,through the reasonable organization,system design to ensure the tire side trimming knife precision components,improve the tire quality,the main contents are as follows:1.The working principle of the automatic trimming machine of TB tire,building design and the overall framework.First elaborated the tire,flow chart is used to explain the tire production process and gives the trimming tire specific structure parameter.Then cited a modular design method,according to the design method of the tire trimming action process tire automatic trimming machine is divided into four parts: pushing device,rotary driving device for tire,tire repair device,playing device.Tire structure design of four separate parts,the four parts assembled into the trimming machine body,and design the work flow,draw the work cycle diagram,thus the whole automatic tire repair machine frame design.2.Analysis of structure design and 1 tool position side assembly of automatic trimming machine of TB tire.Based on the curves on the tire side,the design of the tire trimming action sequence,so that the blade assembly and trimming cutter movement and the structure.In order to determine the initial position of the trimming blade,through simplified 1 tool,analyzed the motion of positive solutions by D-H coordinate method,and then use the correct Matlab and Pro/E cutter head motion equation is verified,then the inverse kinematics motion of each component 1 tool.Calculate the parameters of the motion relationship between the various components of the mechanism can make the blade it is exactly in the different types of tire initial position(inside diameter of lanugo),so as to ensure complete removal of the blade lanugo,improve trimming quality.3.The analysis of the TB automatic tire repair force components in the three side edge machine tool position arrangement and tires.By determining the initial position of the tool edge of the repair,the size of each component of the numerical mechanism,on the basis of the designof the reasonable place II,the initial position and component size value III tool three,can make the blade to fit the reasonable combination of the tire side good.Through HyperMesh and ABAQUS finite element analysis software modeling and analysis of TB tire,the deformation failure of the maximum pressure,and then guide the three knife cylinder size and inlet pressure relationship.Through kinematics analysis software Pro/E displacement.The trimming tool speed and acceleration analysis,finally through 3D modeling software to complete the assembly of side components.4.Design of TB control system of the tire side edge tool automatic repair At the TB tire trimming machine tool system function analysis,completed the design of gas,electric control system.The design of pneumatic control system,the selection of the cylinder,completed the design of pneumatic system and gas diagram;electronic control system design,the barcode reader,increment type encoder the selection and analysis.According to the control process of TB side trimming machine components of tire trimming to complete the design of PLC logic control,and a prototype,to achieve the TB tire trimming machine tool automatic,high precision operation. |
