我厂开发生产的S25系列双臂树脂砂混砂机二级搅笼轴采用如图1所示的六棱轴。为了保证图样的设计要求,我们设计了一套如图2所示的专用分度夹紧装置,将其安装在B2016龙门刨床上加工六棱面。经生产实践证明,该夹具定位准确,夹紧可靠,结构简单操作使用方便,既保证了加工精度,又提高了工效。 I plant development and production of S25 series of arms sand mixer two stir-cage shaft axis shown in Figure 1 as the six-axis. In order to ensure the design requirements of the design, we designed a set of special indexing clamping device as shown in Figure 2, which is installed on the B2016 planer for processing hexagonal surfaces. The production proved that the fixture positioning accuracy, reliable clamping, simple structure and easy operation, both to ensure the processing accuracy, but also improve work efficiency.
