Embodiment 1

[0032] A robot joint of a robot pushing a ring mechanism at a fixed angle, such as figure 1 shown, including:

[0033] Joint outer frame; the middle part of the joint outer frame is rotatably connected with the main joint shaft 11, and the rear end of the joint outer frame is provided with a connecting ring 9 for fixed axis fixed connection to the joint arm, and the middle part of the connecting ring 9 is provided with a power input disk 10, and The input disc 10 is coaxially fixed with the main joint shaft 11, and the power input disc 10 is used to connect one of the swing arms. The power output disc 8 is coaxially fixed at the position of the main joint shaft 11 at the front end of the joint frame, and the power output disc 8 is used for for connecting another swing arm;

[0034] Wherein, an upper cavity and a lower cavity are arranged in the outer frame of the joint, and a rotating cavity is arranged between the upper cavity and the lower cavity;

[0035] The upper push rin...

Abstract

The invention discloses a robot joint of a robot fixed-angle pushing ring mechanism, and belongs to the technical field of robot accessories. A robot joint of a robot fixed-angle pushing ring mechanism comprises a joint outer frame, the joint outer frame is rotationally connected with a main joint shaft, a connecting ring is arranged on the joint outer frame, a power input disc is arranged in the connecting ring, the power input disc and the main joint shaft are coaxially fixed, and the power input disc is used for being connected with one swing arm. A power output disc is further arranged on the joint outer frame and used for being connected with the other swing arm. A fixed-angle driving mechanism driven by the fluted discs is arranged in an original robot joint arm, mutual pushing of the right-angle fluted discs is utilized, so that the fluted discs are meshed and slide, the swing angle of the robot swing arm is slightly adjusted, the whole fluted disc pushing mechanism is pushed by adopting a worm and gear pushing mechanism. And the mechanism is prevented from loosening by utilizing the self-locking effect and the high torque effect of the worm gear and the worm.

Description

technical field [0001] The invention relates to a robot joint of a robot fixed-angle pushing ring mechanism, which belongs to the technical field of robot accessories. Background technique [0002] The robot swing arm is the main driving mechanism of modern industrial robots. It mainly drives the two swing arms to swing through the differential motion of the servo motor; the precision of the swing arm is also affected by the precision of the rotation angle of the servo motor; but for some loads For a large robot swing arm, because the magnetic resistance of the servo motor is limited, the swing of the robot swing arm will produce a certain amount of frame, so it is easy to reduce the accuracy of the swing arm. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the technical problem in the prior art that the precision of the swing arm of the robot becomes low under the state of heavy load, and provide a robot joint ...
