Detailed ways

Tooling equipment for machining the outer circle of the motor stator core, including a cylinder 1, a rib 2, an annular expansion block 3, a screw rod 4, and a dome-shaped positioning block 6, and the cylinder 1 is provided with a Through the opening, the caliber of the cylinder 1 can be expanded or reduced. On the inner wall of the cylinder 1, four ribs 2 are fixedly arranged along the longitudinal interval of the cylinder body, and the distance between every two adjacent ribs 2 is 90°. Circumferential angle, and the length of the cylinder 1 is equal to the length of the ribs 2, and the inner surfaces of both ends of each rib 2 are respectively provided with conical surfaces 7 with equal taper; both ends of the screw rod 4 are provided with threads respectively Through the two ring-shaped expansion blocks 3, the two ring-shaped expansion blocks 3 are movably arranged in the circular holes formed by the tapered surfaces 7 of the four ribs 2 at the two ends of the cylinder 1. By adjusting The trapezoidal nuts 5 screwed on the two ends of the screw rod 4 make the two opposite ring-shaped expansion blocks 3 move toward each other or move in the opposite direction along the tapered surface 7 on the rib 2, thereby realizing the expansion or expansion of the diameter of the cylinder 1. Narrowing; the outer surfaces of the two ring-shaped expansion blocks 3 are respectively provided with dome-shaped positioning blocks 6, and the center of circle of the dome-shaped positioning blocks 6 is concentric with the center of circle of the ring-shaped expansion blocks 3.
