Abstract

The invention discloses a robot wrist part, which comprises a box body, a wrist shell, a rotary disc, a first driver, a first transmission mechanism, a second driver and a second transmission mechanism, wherein the wrist shell is rotatablely connected with the box body; the rotary disc is rotatablely connected with the wrist shell; the first driver is used for driving the wrist shell to rotate; the first transmission mechanism is arranged between the first driver and the wrist shell; the second driver is used for driving the rotary disc to rotate; the second transmission mechanism is arranged between the second driver and the rotary disc; the first driver and the second driver are arranged on the box body; the wrist shell is arranged outside the box body; and the first transmission mechanism and the second transmission mechanism are adjacently arranged in the box body and are both positioned on one side of the wrist shell. According to the robot wrist part, the transmission mechanisms for controlling rotation of the wrist shell and self-rotation of the rotary disc are arranged on one side of the wrist shell respectively; the robot wrist part has a more compact structure; the space occupied by the integral structure of the robot wrist part is reduced; and the robot wrist shell, the rotary disc and a control mechanism are integrated, so that a robot is convenient to mount, debug and maintain.

Description

technical field [0001] The invention relates to a robot wrist, a robot upper arm and an arc welding robot. Background technique [0002] Vertical multi-joint robots generally have more than 4 joints, and the axes of their adjacent joints are mostly perpendicular to each other. Vertical multi-joint industrial robots with a small load of no more than 20Kg are generally used in industrial automation fields such as arc welding, handling, and machine tool loading and unloading. Arc welding occupies the largest proportion. In the early days, arc welding robots generally used general-purpose industrial robots, which can be used in various industrial automation fields such as welding, handling, gluing, and machine tool loading and unloading. General-purpose industrial robots are mainly relative to some special models such as spraying, palletizing and other robots. [0003] In the arc welding integration process, the user needs to integrate the required peripheral equipment such as...
