对一特殊扇形陶瓷件的传动定位方式及夹具进行研究，设计蜗杆传动和圆弧导轨传动相结合的传动定位平台与活动扒爪的夹紧机构，通过对活动扒爪机构的受力分析，计算得到其运动的临界压力角，不仅使刀具在铣削过程中与装夹机构不发生干涉，而且为加工扇形陶瓷件提供所需夹紧力。从而简化运动定位方式，降低成本，提高陶瓷件的加工精度等。对后期具体设计制作具有很强的工程实用价值。

This article made research on drive positioning mode and fixture in order to machine a special fan-shaped ceramic parts. A drive positioning platform was designed by combining worm drive with circular rail drive and a dexterous claw mechanism was designed for clamping this fan -shaped ceramic parts. Through stress analysis of the dexterous claw mechanism, the zero pressure angle was calculated during the movement. This dexterous claw mechanism not only avoid interfering with the tool during milling, but also provided clamping force for machining this fan-shaped ceramic parts. In summary this can simplify the positioning and movement mode, reduce the cost, improve the machining precision of ceramic parts and so on. It has a strong the actual application significance for the manufacturing.
