Mechanical clamping jaw for mechanical manufacturing

The invention discloses a mechanical clamping jaw for mechanical manufacturing. The mechanical clamping jaw comprises a connecting base, a motor is connected above the connecting base, a rotating shaft is connected to the power output end of the motor, a thread is arranged on the rotating shaft, nuts are threadedly connected to the rotating shaft, the other end of the rotating shaft penetrates through the connecting base and is mounted under the connecting base, a limiting plate is arranged in a connection mode, support frames are symmetrically arranged on the two sides of the limiting plate,the support frames are arranged toward the connecting base, driving arms are hinged to the support frames, the upper ends of the driving arms are hinged with the nuts, and the lower ends of the driving arms are hinged to limiting clamping blocks. Compared with the prior art, the mechanical clamping jaw has the advantages than the structure is simple, implementation is easy, clamping is stable, andusing and operation are c
