Motor end cap screwing machine

The utility model provides a motor end cap screwing machine. The screwing machine comprises a feeding fixation plate and a rotation fixation plate which are mutually corresponding. The feeding fixation plate is provided with a feeding device; the rotation fixation plate is provided with a rotation device; the feeding device can hold a motor with a motor end cap; the feeding device transmits the motor with the motor end cap to the place under the rotation device; the rotation device comprises a plurality of rotation shafts in one-to-one correspondence with fan-shaped pieces, and a rotation shaft driving structure connected with the plurality of rotation shafts; the lower end surface of each rotation shaft is provided with a clamp groove; the fan-shaped pieces can be clamped into the clamp grooves of the corresponding rotation shafts respectively; an axis of each rotation shaft is overlapped with a rotation axis of the corresponding fan-shaped piece; and the rotation shaft driving structure can drive each rotation shaft to rotate around the axis. According to the motor end cap screwing machine, the fan-shaped pieces are rotated through a machine instead of an existing manual operation mode, thereby improving productivity and product quality, and saving occupation space and manpower cost.
