活塞销孔精加工影响因素与对策

Influences and Measures of Final Machining of Piston Pin Bore

活塞机械加工中,有不少加工工序是以活塞销孔为定位和夹紧面的,故其加工质量直接影响活塞整体加工质量。结合生产实际情况,针对有特殊要求的活塞销孔的精加工方法展开研究。主要研究活塞销孔精加工的现有手段和工艺要求,分析了影响活塞销孔精加工质量的因素,从而采取相应的措施。这些措施提高了活塞销孔精加工质量,并降低了精加工成本。

The machining quality of piston pin bores directly affacts that of a piston because the piston pin bores provide setting and clamping for many other machining processes.A study on the final machining of piston pin bore that has special requirement was carried out based on the actual production conditions,focusing on the existing machining methods and process.The influences on the quality of the final machining of piston pin bore were analyzed and the countermeasures were taken.These measures were proven to be effective.They have raised the quality of the final machining of piston pin bore and reduced the cost.
