我厂试制引进的控制阀块,有六种不同方位的凸轮以及三种不同规格的手柄需加工12×12、19×19、27×27三种方孔,光洁度要求达到▽_5。凸轮外圆Ф39,厚8毫米。由于工件较薄和外形直径不大,孔与凸轮又有方位要求,这对工件的装夹、定位和加工增加许多困难。为了保证产品加工质量,如期完成试制任务,我们设计了12×12、19×19、27×27三种规格的推刀和方孔推切装置。从首批以及批量投产的控制伐各种凸轮和手柄的质量
I plant trial introduction of the control valve block, there are six different directions of the cam and three different specifications of the handle to be processed 12 × 12,19 × 19,27 × 27 three square hole, finish requirements ▽ _5. Outer cylindrical Ф39, 8 mm thick. As the workpiece is thin and the shape of the small diameter, holes and cams have azimuth requirements, which the workpiece clamping, positioning and processing to increase many difficulties. In order to ensure the quality of product processing, trial completion of the task as scheduled, we designed the 12 × 12,19 × 19,27 × 27 three kinds of specifications pushing and square hole to push the device. Control the quality of various cams and handles from the first and batch production controls
