我厂在成批制造生产BJ-130汽车转向节(见图1)的铣削锥孔两端面的工序中,对其毛胚面一直没有采用合理的定位基准,致使铣削出的锥孔两端与轴颈中心以及对毛胚外形产生严重的形位超差。为了保证和提高BJ-130汽车转向节的产品质量,特设计一种自动平行定位浮动夹紧装置(见图2)使工件在本道工序中达到预想的效果。此工装在使用过程中对工件的定位基准性能稳定、装夹牢固, I plant in mass production BJ-130 car steering knuckles (see Figure 1) milling cone both ends of the process, the blank surface has been no reasonable positioning benchmark, resulting in both ends of the tapered bore milling and Journal centers and shape of the rough shape of the embryo out of tolerance. In order to ensure and improve the quality of the BJ-130 car steering knuckle, an automatic parallel positioning floating clamping device (see Figure 2) is designed to achieve the desired effect of the workpiece in this process. This tooling in the course of the positioning of the workpiece benchmark performance and stability, clamping firm,
