Abstract

The invention belongs to the technical field of industrial robots, and particularly discloses a robot wrist. The robot wrist comprises a forearm base body, a wrist base body, an autorotation driving mechanism, a pitching driving mechanism and an auxiliary supporting mechanism, wherein the auxiliary supporting mechanism is used for supporting the pitching motion of the wrist base body in an auxiliary mode; a cavity is formed in the wrist base body, the autorotation driving mechanism is arranged in the cavity, and the autorotation driving mechanism comprises an autorotation driving motor and anautorotation speed reducer; and the pitching driving mechanism comprises a pitching speed reducer. The invention further discloses a using method of the robot wrist. The using method comprises an autorotation control step and a pitching control step. The invention belongs to a motor front-mounted type, and has high pitching freedom degree and high autorotation transmission precision.

Description

technical field [0001] The invention belongs to the technical field of industrial robots, and in particular relates to a robot wrist and a using method thereof. Background technique [0002] The modern robot wrist is also called the robot posture mechanism, such as figure 1 As shown, the posture of the wrist base can be determined by three orientations, which are roll angle α, pitch angle β and rotation angle γ. The upper arm 1, the lower arm 2 and the wrist 3 are connected sequentially, and the graphic posture of the wrist 3 can be regarded as being in X 3 Direction of wrist 3 first around Z 3 in plane X 3 o 3 Y 3 Rotate within angle α, then in Y 3 with Z 3 Composed of vertical plane Y 3 o 3 Z 3 The angle β is rotated upwards to obtain, if 0°≤α≤360°, 0°≤β≤360°, 0°≤γ≤360°, the wrist 3 is fully flexible. [0003] Modern robot wrists are divided into three-degree-of-freedom wrists and two-degree-of-freedom wrists in terms of structure. Among them, two-degree-of-free...
