【摘要】 设计了一种用于管道检测机器人的旋转夹兵,该夹具能够在100～200mm以及200～400mm范围内对管道实现变径剖分式夹紧。其中的夹盘利用互齿的“V”型槽滑块自动定心原理,通过螺母丝杠驱动滑决并夹紧管道。用有限元方法分析了夹盘受力场状态,找到了“V”型槽滑块关键尺寸的设计依据。对机器人整体夹紧装置做了描述,其中包括剖分式框架。该装置作为一种夹紧与自动定心支撑平台,可广泛应用到管道无损检测、焊接与切割等工艺设备上。更多还原

【Abstract】 A rotation jig applied to pipe inspection manipulator is designed. It can clamp the pipe whose diameter ranges from 100 to 200 mm and 200 to 400 mm with split structure. The self-centering mechanism of engaged V shaped slide is realized in the jig and the slides are driven by the motion of nut-screw to tightly clamp the pipe. The stress field of the jig is analyzed by finite element method and the key dimensions of V-shaped slide are established. The whole jig including split frame is described also. As a kind of clamping and self-centering backing platform, its application ranges from devices of nondestructive detection to welding and cutting technology etc.更多还原
