汽车空调活塞加工机床的自动化改造

目前汽车活塞的加工大多采用单机数控模式。考虑活塞产品量大且品种较为固定的特点,为全面实现柔性自动化加工,在分析汽车空调活塞生产工艺流程的基础上,根据企业现有的数控设备条件,综合考虑零件加工精度、速度、可靠性等方面问题,对零件自动化上下料机构、检测与装夹机构、控制系统等进行分析,提出一种切实可行的数控机床改造方案,在保持机床原有操作习惯的基础上,大大提高产品加工效率及质量的稳定性和可靠性,改善了PXE活塞加工的自动化水平。该技术目前已在企业实现中试,具有较好的应用价值,同时可为其他企业实现"机器换人"提供很好的示范作用。

Automatic Reform of Automobile Air Conditioning Piston Machine Tool

At present, in machining of automobile piston, single machine numerical control mode is adopted. Because piston pro-duction has the characteristics of large amount and fixed variety, in order to achieve flexible automation, on the basis of analyzing the technological process of automobile air conditioning piston production, according to the existing CNC equipment conditions of the enter-prise, comprehensively considering the parts machining accuracy, speed, reliability and other issues, the parts automatic feeding mechanism, inspection and clamping mechanism and control system were analyzed, a feasible reform scheme for NC machine tool was proposed on the basis of keeping the machine tools’ original operating habits. So the product processing efficiency and the stability and reliability of product quality are greatly improved, and the automation level of PXE piston machining is improved. The technology has been carried out pilot-scale experiment in enterprise, it has good application value. While it provides a good role model for other com-panies to achieve “Machine Substitution”.
