　　平板式振动器机座的工艺工装设计
　　摘  要：分析了平板式振动器机座的技术要求，根据大批量生产类型，制定了平板式振动器机座的机械加工工艺过程，设计各加工工序，包括各加工面和孔的加工方法、方案和切削用量的选择。对加工精度要求高的孔采用粗镗—半精镗—精镗的加工方法，平面的加工采用粗铣－精铣的方法。根据基准统1原则，选择平板式振动器机座底面及其上两工艺孔为精基准。同时设计了平板式振动器机座加工过程中的铣夹具、镗夹具和钻夹具。其中铣两端面夹具和镗主轴孔夹具采用＂1面两孔＂ 定位，螺旋压板夹紧；钻端面3个孔夹具采用＂1圆面和1防转销＂定位的盖板式钻模.

　　Process planning and Fixture over The chassis of Flat-vibrator
　　Abstract：This thesis analyzes the technical requirements on the chassis of flat-vibrator, formulates its machining process, and plans all processing techniques according to the mass-production type, including processing methods of all machined sueface, processing plan and the choice of cutting amount. The processing method of rough boring-boring-precision boring is adopted.in high precision hole and the rough milling-precision milling method is used in plane process.According to the principle of the basis unity, the botton and two technique holes of the chassis of flat-vibrator are choosed as precise basis. At the same time, it designs the milling , drilling and boring fixtures used in machining process of the chassis of flat-vibrator. Among the three fixtures, milling side fixture and boring fixture use＂one surface-two holes＂position with spirial platen clamping and 3 hole drilling fixture uses ＂one cylinder-one bolt＂position with plat drilling mould.
