Abstract

The invention discloses a special neck joint structure for a three-degree-of-freedom robot, which belongs to the field of industrial robot joint design. It includes an outer connecting piece B for installing the robot head, an inner connecting piece installed on the outer connecting piece B using a cylindrical hinge, an outer connecting piece A connected with the robot body, and an outer connecting piece A installed on the outer connecting piece A. The freely rotating gear shaft C, the gear shaft D meshed with the gear shaft C, the motor C fixed on the outer connecting piece B through the motor C frame, the gear shaft B and the motor B installed on the inner connecting piece 1. The gear shaft A installed on the outer connecting piece B and meshed with the gear shaft B for transmission. The invention is a special neck joint structure with more reasonable structure, more stable movement, which can be used in industrial robots and has three degrees of freedom of movement.

Description

technical field [0001] The invention mainly relates to the field of industrial robot joint design, in particular to a special neck joint structure for a three-degree-of-freedom robot. Background technique [0002] The neck joint design of the robot has important decisive significance for the performance of the whole robot. The neck joint in the prior art usually has only one torsional degree of freedom, and it is difficult to realize the complex movement effect of the robot head, which is very unfavorable for industrial robots, especially robots for special operations. Therefore, it is of great significance to design a neck joint structure with three degrees of freedom of motion. Contents of the invention [0003] The technical problem to be solved by the present invention is: aiming at the technical problems existing in the prior art, the present invention provides a special neck joint structure with more reasonable structure, more stable motion, which can be used in ind...
