The invention provides a sampling mechanical arm and a Mars aircraft, and belongs to the field of mechanical arms. The problems that traditional mechanical arms are large in weight and size, some telescopic mechanical arms need to be adjusted through additional motors, convenience is poor, and additional weight needs to be increased are solved. The mechanical arm comprises a mechanical arm wrist ring, a motor, a sliding seat, a threaded shaft and a grabbing assembly, the mechanical arm wrist ring is of a three-section telescopic sleeve structure, the motor is fixedly connected to the interior of the sleeve at the uppermost end, the threaded shaft with external threads is arranged on an output shaft of the motor, and the lower portion of the threaded shaft is in threaded connection with the sliding seat with an internal threaded hole; the sliding seat is slidably connected into the sleeve at the lowest end of the mechanical arm wrist ring, the grabbing assembly is rotationally connected to the tail end of the mechanical arm wrist ring, and the lower end of the sliding seat is connected with the grabbing assembly. The motor can be used for driving the fingertip to grab a sampled object, and the weight margin can be provided for aircraft sampling to a greater extent.
本发明提出了一种采样机械臂及火星飞行器,属于机械臂领域。解决了传统的机械臂重量大,体积大,一些可以伸缩的机械臂需要用额外的电机进行调节,便利性差,且需要增加额外的重量的问题。它包括机械臂腕环、电机、滑动座、螺纹轴和抓取组件,所述机械臂腕环为三段伸缩套筒结构,所述电机固定连接在最上端的套筒内,电机的输出轴上设有带外螺纹的螺纹轴,螺纹轴下部螺纹连接有带内螺纹孔的滑动座,滑动座滑动连接在机械臂腕环最下端的套筒内,所述抓取组件转动连接在机械臂腕环的末端,所述滑动座下端与抓取组件相连。它能够利用电机驱动指尖完成对采样物的抓取并可以更大限度的为飞行器采样提供重量裕度。
