Crankshaft Forming Grinding Wheel Dressing And Surface Measurement Problem Research

As the rapid development of China’s industrial machinery parts precision workpiece measurement positioning requirements increasing. Domestic grinder NC rate is generally high, therefore, put forward some common cylindrical grinder NC transformation, improve the level of modernization of China’s machine tool numerical control system based on the secondary development of new methods and techniques, has a very important significance.Cylindrical grinder before grinding crankshaft workpieces need to be trimmed molding grinding wheel on the crankshaft. General CNC grinder using a diamond pen grinding wheel dressing, but you can not simultaneously achieve both repair the left fillet, repaired another right fillet, thus affecting the efficiency of the grinding workpiece. The proposed method has great practical value and practical significance. Crankshaft workpiece grinding extra bed processing crankshaft neck or processing Crankpin, processing methods, regardless of the grinding wheel servo or eccentric Clamp, face orientation is concerned, the main purpose is to hope that the grinding wheel alignment The surface of the intermediate position of the both ends of the crankshaft grinding parts. The proposed meter of the crankshaft workpiece measurement positioning significance.The face measuring instrument when measurement is performed on the workpiece in the workpiece, the position of the lever can not be determined in the case of unmanned observation, so can not make the automatic detection of the NC program control probe may lead to the sensor head and lever collision. In view of this situation, this paper presents the the spindle lever anti-collision technology.Problems encountered in the actual production of CNC machine tools, methods and techniques of several solutions, and do the following work:(1) The use of CNC machine tools, a double diamond pen crankshaft forming wheel dressing process is realized through PLC programming, and to describe the process. Described the double Vajra Note on the use of dual Diamond analyze the advantages and disadvantages of the crankshaft molding Dresser.(2) End measurement positioning problem in the first meter Measuring end and contactless face Meter both end face Meter description, then the use of the meter’s analysis and use brief and PLC programming, implementation, and analysis of the advantages and disadvantages of the use meter. (3) On the the workpiece spindle lever anti-collision technology to solve the main problems are:1、the cause of the spindle lever and the end face of the measuring instrument probe anti-collision technology analysis.2、the sensor used in the anti-collision technology analysis and selection.3、By theoretical analysis of the sensor the spindle lever end measuring instrument probe anti-collision method.
