Abstract

The invention belongs to the technical field of robots, and particularly relates to a hinge-type robot joint. It includes a base, a waist seat, a large arm, a three-axis drive assembly, a small arm, a wrist shaft assembly and an end flange. The waist seat is arranged on the base and is rotatably connected to the base. One end of the big arm is rotatably connected to the waist seat, and the other One end is rotatably connected with the three-axis drive assembly, one end of the forearm is rotatably connected with the three-axis drive assembly, the other end is rotatably connected with the wrist shaft assembly, the end flange is rotatably connected with the wrist shaft assembly, and is hinged with the forearm, the three-axis drive assembly It is used to drive the rotation of the forearm relative to the three-axis drive assembly, the rotation of the wrist shaft assembly relative to the forearm, and the rotation of the end flange relative to the wrist shaft assembly. The invention adopts the hinge structure, which simplifies the joint structure, has low transmission viscous resistance, and has high energy saving and environmental protection efficiency; meanwhile, the inertia is small and the control difficulty is low.

Description

technical field [0001] The invention belongs to the technical field of robots, and particularly relates to a hinge-type robot joint. Background technique [0002] Conventionally, an industrial robot includes an arm and a wrist, and the wrist is rotatably connected to the arm, and the industrial robot is configured such that the wrist is driven to rotate by an actuator, and is attached to a distal end by means of an actuator. The end effector (such as a torch for arc welding, etc.) is used to perform specified operations. Conventionally, there has been disclosed an industrial robot including a plurality of linkers rotatably connected to each other, and an end effector (for example, arc welding for example) attached to the tip of the linker while rotating the linker by an actuator is disclosed. Use a welding torch, etc.) to carry out the prescribed work. [0003] Conventionally, there have been proposed industrial robots that include a plurality of links rotatably connected ...
