Mechanical arm anti-deviation structure and mechanical hand
This application relates to the field of photovoltaic installation technology, providing a robotic arm anti-deviation structure and a robotic hand. The robotic arm anti-deviation structure includes a double-ended bolt with oppositely oriented threads at both ends; a rotating shaft passing through one end of the robotic arm and two side plates oppositely positioned on both sides of the robotic arm, allowing the robotic arm to rotate relative to the side plates via the rotating shaft; a fixing member for connecting the double-ended bolt and the rotating shaft, the fixing member having a screw hole and a insertion hole, the axis of the screw hole being parallel to the axis of the insertion hole; one end of the double-ended bolt is threadedly connected to the robotic arm, and the other end of the double-ended bolt is threadedly connected to the fixing member through the screw hole; the end of the rotating shaft is inserted into the insertion hole and abuts against the fixing member, allowing the fixing member to rotate around the rotating shaft via the insertion hole. The robotic hand includes the aforementioned robotic arm anti-deviation structure. This application has a simple structure and ingenious design, which can limit the relative movement between the robotic arm and the base, prevent the robotic arm from deviating, reduce the impact on the positioning accuracy of the robotic arm's end effector, and ensure installation or handling accuracy.
