车梁加工用翻转台的设计 摘要：重型卡车在建筑、矿场等的需求量很大，重型卡车的生产效率决定了市场经济效益。车梁对于车架而言是最基本的基础，决定了车身的安全性能。针对国内车梁加工采用单摇臂钻床靠模加工，加工效率低下，加工精度低，搬运不方便。经过分析单摇臂钻床靠模加工的缺点，对纵梁钻孔翻转系统的设计进行了改进，通过大梁台箱装置的翻转，只需一次安装和定位，减少了车梁的翻转装卸次数，从而减少了反复装卸和定位所引起的定位和加工误差。不仅提高了加工效率，而且增加了厂家的经济效率。 关键词：纵梁钻孔 装置 系统设计 指导老师签名： Cars with Flip Platform of Beam Processing Design Abstract：Heavy trucks in architecture, mines etc of great demand and heavy-duty truck production efficiency decided market economic benefits.As for car beam frame is the most basic foundation, decided to the body the safety performance. For the domestic car beam processing by a single radial drilling machine, processing modeling efficiency is low, the processing precision low, handling inconvenient. After analysis modeling single radial drilling machine processing faults, for longitudinal design of drilling flip system were improved, through the girders of Desktop cabinet device, only a flip, reducing the installation and positioning the flip loading and unloading car beam, thus reducing the number of repeated loading and unloading and locate the positioning and caused processing error. Not only increase the processing efficiency, but also increased the manufacturers of economic efficiency.
