Embodiment Construction
[0025] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0026] The invention provides a high-precision mechanical arm joint driven by a synchronous belt, which uses a stepping motor instead of a servo motor as the driving device of the robot joint, reducing the cost of the joint; using a planetary reducer instead of a harmonic reducer as the reduction device of the robot joint, reducing Cost of the joint; use the synchronous belt to offset the output rotation axis of the joint from the axis of the motor, so that the joint can conveniently realize the hollow wiring scheme; use the photoelectric switch as the position detection sensor of the joint, and design the photoelectric switch baffle to detect Joint zero position.
[0027] Such as figure 1 Shown is the front view of the manipulator joint. It can be seen from the figure that a synchronous belt transmission type high-precision manipulator joint i...

A high-precision mechanical arm joint driven by a synchronous belt relates to the field of robot configuration and structural design; it includes a joint casing, a stepping motor, a planetary reducer, a small pulley, a large pulley, a synchronous belt, a first joint bearing and a large Pulley bracket; the stepper motor is fixedly installed in the middle of the joint casing; the planetary reducer is connected to the output shaft of the stepper motor; the output shaft of the planetary reducer protrudes from the side wall of the joint casing; the small pulley is set on the output of the planetary reducer The outer wall of the shaft; the large pulley bracket is installed at the lower end side wall of the joint shell; the first joint bearing is arranged between the large pulley support and the lower end side wall of the joint shell to realize the rotation of the large pulley support relative to the joint shell; the large pulley Set on the outer wall of the large pulley bracket; the synchronous belt is set on the outer wall of the small pulley and the large pulley to realize the transmission; the invention reduces the cost of the joint, so that the joint can conveniently realize the hollow wire routing scheme, and at the same time realizes zero detection of the joint. bit position.
Description
technical field [0001] The invention relates to the field of robot configuration and structural design, in particular to a high-precision mechanical arm joint driven by a synchronous belt. Background technique [0002] The robot joint is the basic component of the robot, and its performance directly affects the performance of the robot. There are many types of robot joints. According to the different functions of the robot, the configuration of the joints and the form of the motion system are also different. [0003] The common joint forms of robots are mobile joints and rotational joints. The most widely used robot is a multi-joint robot, which is mainly composed of multiple rotary joints and connecting rods, simulating the functions of human shoulder joints, elbow joints and wrist joints. [0004] The current mainstream collaborative robots all adopt the joint design of "modularization", adopting the method of direct drive motor + harmonic reducer. The internal structure...
