Abstract


Cylinder honing is an important part of the automotive engine cylinder repair process . With the increase in car ownership , the amount of engine maintenance also surged . Cylinder honing machine is the necessary equipment of more than two car repair business . Currently , most repair companies use , or manually adjust the stroke stop small simple honing machine cycle control different types of machining the cylinder when the process parameters adjustment takes time longer , and it is difficult to accurately control , resulting in the production low efficiency , poor accuracy maintenance and the technical requirements for processing personnel . Thesis analyzed on the basis of a honing process to identify several key issues , affecting the processing efficiency and accuracy parameter options to achieve shorter processing time , reduce labor intensity and improve the machining accuracy of the purpose . 3M9814 honing machines for use in recent years a large amount of aviation equipment production plants the following aspects : 1 according to the characteristics of the machining process to identify the key control parameters honing should explore the use of precise control of honing head speed, stroke and sand bars poked amount , so that the processing speed , accurate angle between more fine textured , more accurate size . Designed a loop control system , the application of computer control proportional valve to determine the speed of grinding head back and forth , with optical encoder control stroke reversal point . The structure is simple, fast and accurate positioning . 3 . Microcomputer control system hardware design , the system uses AT89C52, through the peripheral chip expansion and the auxiliary circuit design , so that the system can be carried on of stroke positioning honing stroke and short -stroke digital control . 4 , the control system software developed internally based on the commonly used models to establish the the cylinder parameter data table , user-friendly call . Can increase processing models data processing needs , honing the need to adapt to the new models . 5 conducted experiments to verify the feasibility of the design and the inadequacies .
