Abstract

The invention belongs to the technical field of robots, and particularly relates to a hinge type robot joint. The hinge type robot joint comprises a bottom seat, a waist seat, a large arm, a three-axis driving component, a small arm, a wrist shaft component and a tail end flange, wherein the waist seat is arranged on the bottom seat and is rotatably connected with the bottom seat; one end of the big arm is rotatably connected with the waist seat; the other end of the big arm is rotatably connected with the three-axis driving component; one end of the small arm is rotatably connected with the three-axis driving component; the other end of the small arm is rotatably connected with the wrist shaft component; the tail end flange is rotatably connected with the wrist shaft component and is hinged to the small arm; and the three-axis driving component is used for driving the small arm to rotate relative to the three-axis driving component, the wrist shaft component to rotate relative to thesmall arm, and the tail end flange to rotate relative to the wrist shaft component.

Description

technical field [0001] The invention belongs to the technical field of robots, in particular to a hinged robot joint. Background technique [0002] Conventionally, an industrial robot has an arm and a wrist, and the wrist is rotatably connected to the arm, and the industrial robot is configured to drive the rotation of the wrist by an actuator while being attached to the terminal The end effector (such as a welding torch for arc welding, etc.) performs specified operations. In the past, the following industrial robots have been disclosed: it has a plurality of joints connected to each other in a rotatable manner. Use a welding torch, etc.) to perform the specified work. [0003] Conventionally, an industrial robot has been proposed which includes a plurality of links rotatably connected to each other and which can A predetermined operation is performed while rotatably driving the link by using the actuator. Existing industrial robots have complex structures, need to rely...
