The invention relates to a machining technology of a cross-country vehicle steering knuckle, the machining technology is characterized by comprising the following steps of: S1, a main pin hole, a bracket surface, a gear opening surface, a central hole and a branch pin hole of the cross-country vehicle steering knuckle are roughly machined by adopting a first horizontal machining center with an exchangeable workbench; S2, a numerical control turning and milling composite machine tool is adopted for machining all stages of journal machining surfaces, disc surface threads and journal end surfaces at a time; and S3, a second horizontal machining center with an exchangeable workbench is adopted for conducting finish machining on the main pin hole, the bracket surface, the gear opening surface, the central hole and the branch pin hole through journal positioning machined in the step S2. The machining technology has the beneficial effects that the production cost input is low, and the blindness of equipment investment can be reduced through the relatively concentrated technology mode; and logistics links among procedures are greatly simplified, investment is conducted on a production line in batches according to types of production parts and capacity requirements, and investment risks are reduced.
本发明涉及一种越野汽车转向节的加工工艺,其特征在于,包括以下步骤:S1、采用可交换工作台的第一卧式加工中心对越野汽车转向节的主销孔、支架面、开档面、中心孔、支销孔进行粗加工;S2、采用数控车铣复合机床将各级轴颈加工面、盘面螺纹、轴颈端面一次性加工完成;S3、采用可交换工作台的第二卧式加工中心利用S2中加工出来的轴颈定位将主销孔、支架面、开档面、中心孔、支销孔进行精加工,本发明的有益效果为:生产成本投入低且这种相对集中的工艺方式可以降低设备投资的盲目性,大大简化了工序间的物流环节,根据生产零件的类型和产能需求分批对生产线进行投资,降低了投资风险。
