| Spiral bevel gear dynamic performance is good, have an overlap coefficient,smooth transmission, low noise, high bearing capacity, the mounting errorsensitivity is low characteristic, in the automotive, aviation, navigation andall kinds of precision machine tools and other industries are widely used, inthe field of machinery occupies a pivotal position. But the spiral bevel geardesign and processing is very complicated, if an ordinary machining spiral bevelgear, precision and efficiency are not guaranteed; if the numerical controlmachine tool to machining spiral bevel gear, not only improves the machiningprecision, but also improve the machine automation, enhance machining ability,satisfy market demand.For example YK2250,the project in a comprehensive analysis of the contrastbetween domestic and abroad CNC spiral bevel gear processing machine tool basedon, at home and abroad from a similar machine design method, system of thenumerical control system and machine tool each motion control of keytechnologies are studied.The main research job for the paper as follows:1）a detailed analysis of the domestic and foreign various CNC system’sadvantages and disadvantages, after accurate analysis and selection, firstidentified the machine using the NC system, and then completed a feed system,a portion of the spindle, and the auxiliary device for NC rotary table andfunctional components of the control design and selection.2）based on the analysis of spiral bevel gear milling machine tooltechnology on the basis of demand, and discusses design of spiral bevel gearmilling machine tool control system scheme of feed;, spindle, rotary table andother functions to achieve the key technology in the process of the controlsystem, the selection of demonstration and design is put forward; servo motorand drive configuration scheme; based on SEIMENS828D system DNC control scheme;explains the system debugging steps and methods; analysis of the system in theprocess of commissioning fault and problems.Based on the above of the spiral bevel gear processing machine tool controlsystem research, design, analysis, finish machining trial, after assembly,commissioning and trial operation, successfully developed with independentintellectual property rights of the spiral bevel gear processing machine toolYK2250. The research and design of spiral bevel gear machine tool has been handedover to the user, the actual operation can see: system state is good, friendlyman-machine windows, machining accuracy to meet the requirements of thedrawings. Between the axis motion control more flexible; cutting processinga variety of gear line of spiral bevel gear, gear hobbing machine can be usedas cutting all kinds of cylindrical gears, so that the equipment universalgreatly improved. |
