汽车发动机缸体铸件制芯中心工装通用性研究

Investigation on Core Making Center Tools Universality of Automotive Engine Cylinder Block Castings Production

介绍了用制芯中心生产各种不同汽车发动机缸体铸件时确保工装通用性的原则:(1)缸体芯盒中各个砂芯的中心间距始终保持不变,锁芯孔轮廓尺寸始终保持不变;(2)所有芯盒的分盒面到设备工作台平面之间的距离保持一致;(3)各种缸体的去毛刺夹具安装中心线保持一致;(4)涂料机器人抓取位置统一;(5)所有缸体均采用相同的锁芯定位设计和射砂垫;(6)所有缸体的连体芯头部分沿缸孔方向的长短保持一致;(7)制订标准,所有工装制造厂家必须严格遵照执行;(8)所有工装厂家必须使用指定的SMC品牌气缸,必须使用Parker品牌油缸,必须使用Parker品牌阀。

An introduction was conducted to the principles to ensure tools universality when using core-making center to produce different automotive engine cylinder block castings:(1)keeping the spacing distance between central lines of every two neighboring cores unchanged,and keeping the shape and dimensions of the cores-locking holes unchanged;(2)keeping the distance from the parting face of every core boxes to the work table surface of the core-making equipment consistent;(3)keeping the installation central line of the veining-cleaning clamper used for different cylinder blocks consistent;(4)keeping the location for coating robot grasping the cores unchanged;(5)using the same cores-locking design and shooting pad for all types of cylinder blocks;(6)keeping the conjoined core print length of all cylinder blocks along the cylinder hole direction consistent;(7)drawing up relational standards,all core-making tools manufacturers must implement;(8)all tools manufacturers must used appointed SMC brand air cylinders,Parker brand oil cylinders and Parker brand valves.
