Six-axis robot

Abstract

The invention discloses a six-axis robot which comprises a base, a rotating base, supporting big arms, shoulder joints, supporting small arms, wrist joints and a terminal end actuator, wherein a first servo motor is fixedly arranged in the inner cavity in the base, a first harmonic speed reducer is arranged on the lower end of the inner cavity of the rotating base, a second servo motor is fixedly arranged on the upper end of the inner cavity of the rotating base, a second harmonic speed reducer and a third harmonic speed reducer are arranged on the inner cavities of the supporting big arms, a third servo motor and a fourth servo motor are fixedly arranged on the inner cavities of the shoulder joints, a first belt wheel is fixedly connected to the output shaft of the fourth servo motor, a fifth servo motor, a fourth harmonic speed reducer and a fifth harmonic speed reducer are arranged on the inner cavities of the supporting small arms, a second belt wheel is fixedly connected to a soft wheel of the fourth harmonic speed reducer, the second belt wheel is in transmission connection with the first belt wheel through a first synchronization belt, a sixth servo motor and a sixth harmonic speed reducer are arranged on the inner cavities of the wrist joints, and the terminal actuator is fixedly connected with the soft wheel of the sixth harmonic speed reducer. The six-axis robot is good in flexibility and fast in action.

Description

technical field [0001] The invention relates to a robot, in particular to a six-axis robot. Background technique [0002] The six-axis robot is a kind of serial robot. It can move freely in three-dimensional space, and can accurately and quickly perform a large number of repetitive tasks such as handling, welding, and spraying. In traditional factories, this kind of work is basically done manually, which has problems such as high labor intensity, time-consuming, boring, bad working environment, easy to cause pollution, and will increase the cost of the enterprise. Therefore, in these fields, robots are required to carry out operations such as handling, welding, and spraying of objects accurately and quickly. [0003] However, although current robots of this type have sufficient degrees of freedom, due to the excessive number of joints and the complexity of the drive mechanism, they are not dexterous enough, have slow movement speed, and poor precision.
