The invention discloses a feeding mechanical arm for a timber
rounding machine. The mechanical arm has the advantages that the
automation degree is high, feeding is convenient, the efficiency and thesafety are improved, the time-saving and labor-saving effects are achieved, the grabbing space is saved, the grabbing precision is improved, and the problems of unstable grabbing
gravity center, easiness in sliding and the like are solved. The feeding mechanical arm for the timber
rounding machine comprises a paw structure for grabbing round logs and a standard six-degree-of-freedom mechanical arm, wherein the paw structure comprises a
flange plate, a connecting piece, angle iron, a guide rail, racks, a paw groove, a paw and a fastening paw; and the six-degree-of-freedom mechanical arm comprises a mechanical arm base, a
waist rotating seat, a big arm, an
elbow joint, a small arm and a
wrist part, wherein the mechanical arm base is connected with a feeding mechanism. During work, the mechanical arm is moved to a designated position according to a
signal, the two racks are adjusted in relative distance according to requirements so as to adapt to the grabbing
gravity center, the round logs are wrapped through the paw popped out after the semicircular paw groove covers the round logs, and the fastening paw is popped out to fix the round logs.
