The invention discloses a six-degree-of-freedom
industrial robot based on an X-Y-Z rectangular coordinate joint and a posture
wrist. The six-degree-of-freedom
industrial robot based on the X-Y-Z rectangular coordinate joint and the posture
wrist comprises the rectangular coordinate joint and the posture
wrist, wherein the rectangular coordinate joint achieves the degree of freedom of moving in three directions and comprises four linear modules of the same structure, two linear modules are arranged in parallel to be integrated and are in pairwise orthogonality with the other two linear modules; each linear module comprises a motor, a
ball screw, a linear guide rail and a sliding block; the posture wrist is installed at the
tail end of the rectangular coordinate joint, achieves
three degrees of freedom of rotation, and comprises a substrate, three motors, three
harmonic reducers and three transmission mechanisms, the motors are arranged on the rear portion, and each motor corresponds to one rotation joint. The six-degree-of-freedom
industrial robot based on the X-Y-Z rectangular coordinate joint and the posture wrist is compact in structure and achieves the modularization; the parameters of the posture wrist are close to the parameters of a world mainstream industrial
robot; the six-degree-of-freedom industrial
robot based on the X-Y-Z rectangular coordinate joint and the posture wrist has the advantages of being flexible in
tail end, high in reliability, good in universality, high in practicality and
operability, and applicable to various occasions such as
welding and carrying.
