Automatic knocking device and aerial robot

The utility model provides an automatic knocking device, including motor, shaft coupling, cam, rammer and sleeve, the motor with shaft coupling zonulae occludens, and pass through shaft coupling control the cam, through the motor drives the rotation of cam, just the cam with the one end of rammer is connected, cam control the rammer carries out linear motion to utilize when being linear motion the other end of rammer strikes the purpose thing, sleeve fixation and restraint the rammer makes the rammer can only carry out linear motion along telescopic direction. The utility model provides an aerial robot. The utility model provides a technical scheme can improve detection precision and detection efficiency, simultaneously the also very big security that improves the detection. 本实用新型提供种自动敲击装置，包括电机、联轴器、凸轮、敲击棒和套筒，所述电机与所述联轴器紧密连接，并通过所述联轴器控制所述凸轮，通过所述电机带动所述凸轮的转动，且所述凸轮与所述敲击棒的端连接，所述凸轮控制所述敲击棒进行直线运动，并在做直线运动时利用所述敲击棒的另端对目的物进行敲击，所述套筒固定约束所述敲击棒使得所述敲击棒只能沿着套筒的方向进行直线运动。本实用新型还提供种空中机器人。本实用新型提供的技术方案能提高检测精度和检测效率，同时也极大提高检测的安全性。
