Harmonic wave integrated robot joint

The invention discloses a harmonic wave integrated robot joint. Belongs to the technical field of robot structures, adopts coaxial and integrated design of a motor and a harmonic reducer, can tighten the internal structure and reduce the use space, and is simple in structure and convenient to use. Comprising a shell, and a pressure plate and a rotating plate which are arranged in the shell, the pressing disc comprises a transverse part and a longitudinal part which are integrally formed. The longitudinal part away from one end of the transverse part is rotationally sleeved with the rotating disc. A harmonic reducer and a motor are arranged between the transverse part of the pressing disc and the rotating disc; the motor comprises a motor shell, a stator and a rotor; the rotor is in driving connection with the wave generator, the wave generator is in driving connection with the flexible wheel, the rigid wheel fixedly connected with the flexible wheel is arranged on the flexible wheel, the rigid wheel is fixedl
