Robot arm assembly

Abstract

Provided is a robot arm assembly. The robot arm assembly comprises a first mechanical arm, a second mechanical arm, a third mechanical arm and a wire passing hose, wherein the second mechanical arm comprises a first shaft base, a first input shaft, a first bevel gear and a second bevel gear, the third mechanical arm comprises a second input shaft, a second shaft base and an output shaft, the first mechanical arm, the first input shaft and the second input shaft are arranged in a sleeved mode in sequence, the first shaft base comprises a first open end and a second open end, the first open end is fixedly connected with the first mechanical arm, the first bevel gear is fixedly installed at the end, close to the first open end, of the first input shaft, the second bevel gear is installed at the second open end, and is meshed with the first bevel gear, a rotary shaft of the second bevel gear is in oblique crossing with the axis of the second input shaft, the second shaft base is fixedly connected with the second bevel gear, the output shaft is arranged in the second shaft base in a penetration mode, and the wire passing hose penetrates through the first bevel gear and the second bevel gear along the axis of the second input shaft, and is fixedly connected with the output shaft. According to the robot arm assembly, cables in the hose are protected against damage.

Description

technical field [0001] The present invention relates to a robot arm component, in particular to a robot arm component having a plurality of sequentially connected mechanical arms. Background technique [0002] With the development of the machinery industry, more and more robotic arm parts are used in the machining process to realize automated production. With the continuous advancement of technology, robot arm components are gradually developing towards multi-axis to achieve more complex movements. The multi-axis robot arm part is used for spraying, cleaning and other occasions. It is necessary to pass the cables or pipes for conveying liquid such as spraying liquid or cleaning liquid through the multi-axis robot arm part and connect it to the execution end of the multi-axis robot arm part to Spray or wash the workpiece. However, since the central axis of each mechanical arm of the robot is different, when the multi-axis robot arm component is in operation, each mechanical...

AI Technical Summary

Problems solved by technology

However, since the central axis of each mechanical arm of the robot is different, when the multi-axis robot arm component is in operation, each mechanical arm rotates around its own central axis, so that the hose is sometimes straightened and sometimes bent, and the liquid flowing through the hose cannot be kept constant. Speed ​​outflow, resulting in unstable working state of the robot arm parts, thereby reducing its working efficiency

In addition, the multiple bending actions of the hose make the hose easier to damage, resulting in the malfunction of the robot arm parts
