Problems solved by technology

[0005] Due to the many transmission mechanisms in the wrist and the complex structure, there will be deviations in assembly and processing, especially the gear transmission pair requires high installation and processing accuracy. Improper control will result in low transmission accuracy, vibration and noise.

Abstract

The present invention provides a wrist of a six-axis robot arm. This wrist comprises a housing assembly and a transmission structure disposed inside an external assembly. The transmission structure comprises: a six-axis motor, a five-axis motor, a six-axis input shaft assembly, a five-axis decelerator assembly, a six-axis decelerator assembly, a six-axis transmission belt connected between the six-axis motor and the six-axis input shaft assembly, and a five-axis transmission belt connected between the five-axis motor and the five-axis decelerator assembly, wherein the six-axis input shaft assembly is provided with a first arc gear, and the six-axis decelerator assembly is provided with a second arc gear engaged with the first arc gear. The components of the transmission assembly within the wrist of the six-axis robot arm in the present invention are designed as independent modules, and each module is assembled to reduce the dimension chain, reduce the assembly difficulty and increase the assembly precision. The six-axis input shaft assembly and the six-axis decelerator assembly of the wrist transmit power through the arc bevel gear. Therefore, the wrist can increase the transmission torque and reduce noise.

Description

technical field [0001] The invention belongs to the technical field of transmission of industrial manipulators, in particular to a wrist of a six-axis manipulator. Background technique [0002] The commonly used six-axis robotic arm is a manipulator that uses the rotation and movement of the x, y, and z axes to operate. The six-axis robotic arm has 6 degrees of freedom. Its main base (1 axis), arm (2, 3 axes), Wrist (4, 5, 6 axes), driven by the drive system through the transmission mechanism, realizes the required position and attitude of the robot end effector in space. [0003] Such as figure 1 Shown is a schematic diagram of the structure of the existing six-axis robotic arm. The six-axis robotic arm includes a rotary base 1 at the bottom, a first AC servo motor 2, a second AC servo motor 3, a large arm 4, a connecting rod 5, and a small arm 6 , the wrist 7, and the end effector, wherein the rotary base 1 is provided with a servo motor that drives the entire base to pe...
