Pneumatic clamping jaw executing mechanism based on switching mechanism

The invention provides a pneumatic clamping jaw actuating mechanism based on a switching mechanism, which comprises an air cylinder and a clamping jaw head, the air cylinder comprises an outer layer cylinder and an inner layer cylinder, the inner layer cylinder can move in the outer layer cylinder, the clamping jaw head is detachably connected to the inner layer cylinder, and the inner layer cylinder drives the clamping jaw head to act. According to the pneumatic clamping jaw executing mechanism based on the switching mechanism, a positioning robot can achieve the clamping function on a heat transfer pipe of a steam generator, the application range of the positioning robot is expanded, the maintenance cost is reduced, the maintenance time is shortened, and the irradiation dose borne by equipment personnel due to equipment maintenance is reduced. 本发明提供了一种基于转换机构的气动卡爪执行机构，包括气缸和卡爪头，所述气缸包括外层缸和内层缸，所述内层缸能够在所述外层缸内移动，所述卡爪头可拆卸地连接于所述内层缸，所述内层缸驱动所述卡爪头动作。本发明提供的基于转换机构的气动卡爪执行机构能使定位机器人能在蒸汽发生器传热管上实现夹持功能，扩展定位机器人的应用范围，降低维护成本，缩短维
