Robot three-degree-of-freedom wrist device

Abstract

The invention discloses a robot three-degree-of-freedom wrist device. The robot three-degree-of-freedom wrist device comprises flange plates, connecting rods, supporting rods, cross shafts, cylindrical straight gears, driving bevel gears, driven bevel gears, side plates, surrounding plates, guide wheel sets, a first steel wire rope, a second steel wire rope, a third steel wire rope, a fourth steelwire rope, a first motor, a harmonic reducer, a motor frame and rotating holes, wherein the guide wheel sets are fixedly connected to the outer walls of the surrounding plates in a distributed mode;and the side plates are symmetrically and fixedly connected to the inner walls of one sides of the surrounding plates. The robot three-degree-of-freedom wrist device is simple in structure and convenient to use; through cooperative use of the cross shafts, the cylindrical straight gears, the driving bevel gears, the driven bevel gears, the guide wheel sets, the steel wire ropes, the first motor and the harmonic speed reducer, the structure is simple; and through user-friendly appearance structural design, pitching, deflection and rotary motion of the wrist device are achieved, the flexibilityand the operation space of the robot wrist device are improved, and use is convenient.

[0002] With the continuous application of robot technology, the robot wrist has become one of the research hotspots in the field of robots. In the field of new technology development, industrial robots are a very important technology. Sensing technology has formed the current high-tech robot technology, which is widely integrated into all aspects of our modern society, and plays a pivotal role in many fields such as aerospace, industrial production and medical education; the wrist device is an important part of the manipulator. On the one hand, the robot wrist device makes the manipulator have a more anthropomorphic shape structure, on the other hand, it can enhance the flexibility and operating space of the manipulator. In recent years, the field of robotics in my country has also developed rapidly, and domestic enterprises engaged in the robotics industry are also increasing. There are more, but the current situation that the product level is not high and key components rely on imports, especially in some special robot wrists, there are many gaps. Therefore, a new type of robot wrist device with three degrees of freedom is urgently needed at this stage.
