AI Technical Summary
The existing clamping device cannot achieve rotation during the machining of the motor rotor shaft, resulting in frequent loading, unloading and repositioning, which increases the labor intensity of operators and reduces processing efficiency.
A clamping and rotating mechanism was designed. By setting components such as an adjusting plate, a rotating shaft, a three-jaw chuck, an internal gear ring, and gears on the processing table, the rotor shaft can be fixed and rotated. The internal gear ring and the circular plate are rotated by a motor-driven gear, which in turn drives the rotating shaft to rotate, thus achieving synchronous clamping and rotation.
It improves the efficiency of motor rotor shaft machining, reduces the need for frequent loading, unloading and repositioning, and reduces the labor intensity of operators.
