Problems solved by technology
Due to the complex structure of the wrist drive system, at present, the component-assembled harmonic reducer is generally used. The disadvantage of this structure is that the harmonic reducer and the components of the drive system need to be installed on site, and there are many parts and assembly requirements. High, complex installation, and difficult to guarantee transmission accuracy; especially in wrist maintenance, it is also necessary to disassemble and reassemble all parts of the harmonic reducer and transmission system, which not only increases the difficulty of maintenance; moreover, the harmonic reducer and transmission Repeated assembly and disassembly of components will directly lead to the decline of performance and transmission accuracy

The invention discloses a unit assembly type robot wrist. The unit assembly type robot wrist comprises an upper arm, a swing part, a B-shaft transmission and speed reduction unit, a T-shaft speed reduction and output unit and a T-shaft intermediate transmission unit. The B-shaft transmission and speed reduction unit is capable of directly driving the swing part to realize wrist swing movement; the T-shaft speed reduction and output unit directly drives a wrist tool mounting flange and an operation tool to realize wrist rotation; the T-shaft intermediate transmission unit realizes T-shaft directional conversion and is connected between a T-shaft servo drive motor and the T-shaft speed reduction and output unit. The B-shaft transmission and speed reduction unit, the T-shaft speed reduction and output unit and the T-shaft intermediate transmission unit are independent integral parts available for direct assembly and disassembly, and adjustment is avoided in assembly or maintenance, so that wrist mounting and maintenance are greatly facilitated, precision of a transmission system is guaranteed, and the service life of the robot wrist is prolonged.
Description
technical field [0001] The invention relates to the field of industrial robots, in particular to a unit combined robot wrist. Background technique [0002] The wrist of the robot needs to have two rotary motion axes: wrist swing (B axis) and hand rotation (T axis). The rotation speeds of the wrist swing axis B and the hand rotation axis T are both low, so the transmission system must be equipped with a reducer. Due to the complex structure of the wrist drive system, at present, the component-assembled harmonic reducer is generally used. The disadvantage of this structure is that the harmonic reducer and the components of the drive system need to be installed on site, and there are many parts and assembly requirements. High, complex installation, and difficult to guarantee transmission accuracy; especially in wrist maintenance, it is also necessary to disassemble and reassemble all parts of the harmonic reducer and transmission system, which not only increases the difficulty ...
