[0037] Example 2, based on Example 1, such as Figures 5 to 7As shown, the locking part 5 includes a rectangular slide cylinder 501, a rectangular slider 502, a locking wheel 503, a locking groove 504, a locking insert 505, a spring guide rod 506, a limiting slider 507, a hexagonal prism 508, a sliding plate 509, a handle 5010, a limiting block 5011, and an arc-shaped limiting port 5012. The rectangular slide cylinder 501 is fixedly mounted on the U-shaped support plate 401. The rectangular slider 502 is slidably connected inside the rectangular slide cylinder 501. The head end of the rectangular slider 502 is provided with a locking insert 505, and the tail end of the rectangular slider 502 is provided with a spring guide rod 506 that penetrates the tail end of the rectangular slide cylinder 501. A spring is sleeved on the outside of the spring guide rod 506 inside the rectangular slide cylinder 501. The locking wheel 503 is fixedly mounted on the clamping screw 404. The outer circumference of the locking wheel 503 is provided with locking grooves 504 in a ring array. A limiting slider 507 is fixedly connected to the rectangular slider 502. 7. A rectangular sliding opening is provided on one side of the rectangular sliding cylinder 501, and the rectangular sliding opening on the rectangular sliding cylinder 501 is slidably connected to the limiting slider 507. A hexagonal prism 508 is fixedly connected to the limiting slider 507, and a circular limiting plate is fixedly connected to the other end of the hexagonal prism 508. A sliding plate 509 is slidably connected to the outside of the hexagonal prism 508. A spring is sleeved on the outside of the hexagonal prism 508 between the circular limiting plate and the sliding plate 509. A handle 5010 is fixedly connected to the sliding plate 509. A limiting block 5011 is fixedly connected to the outside of the rectangular sliding cylinder 501, and an arc-shaped limiting opening 5012 is provided on the limiting block 5011. Through the setting of the locking part 5, when the stator end plate is clamped and positioned, the locking wheel 503 can be effectively locked and limited, which effectively avoids the clamping screw 404 from loosening and improves the firmness of the clamping and positioning mechanism 4 when positioning the stator end plate.

[0038] The working principle of this embodiment is as follows: When the stator end plate is precision machined, the four stator end plates are first clamped onto the four clamping and positioning mechanisms 4 respectively. When clamping and positioning, the stator end plate is placed into the two arc-shaped clamping grooves 405 opened on the two clamping plates 403. Then, the handle 5010 is inserted into the arc-shaped limiting port 5012, so that the head end of the rectangular slider 502 is retracted into the rectangular slide cylinder 501. At this time, the locking block 505 is separated from the locking groove 504. Then, by manually rotating the clamping screw 404, the two clamping plates 403 move simultaneously in opposite directions under the action of the two reverse threads on the outside of the clamping screw 404, and finally the stator end plate is clamped and positioned.

[0039] After the stator end plate is clamped and positioned, the handle 5010, which is stuck inside the arc-shaped limiting port 5012, is taken out, so that the rectangular slider 502 loses its limiting function. Then, under the action of the spring force outside the spring guide rod 506, the rectangular slider 502 moves with the locking block 505 towards the axis of the locking wheel 503, so that the locking block 505 is inserted into one of the locking grooves 504 on the locking wheel 503, thereby effectively locking and limiting the locking wheel 503 and effectively preventing the clamping screw 404 from becoming loose.

[0040] Then, the stator end plate clamped and positioned on the rear clamping and positioning mechanism 4 is processed by the machining tool installed on the spindle at the lower end of the spindle box 102. After the stator end plate clamped and positioned on the rear clamping and positioning mechanism 4 is processed, the servo motor 302 is controlled by the controller 104 to rotate the shaft clockwise one revolution, thereby rotating the circular turntable 303, the notched disc 305 and the actuating column 304 clockwise one revolution. Then, the actuating column 304, which rotates one revolution clockwise, drives the grooved wheel 301 to rotate counterclockwise by a quarter. One revolution, or ninety degrees, drives the vertical rotating shaft 201 and the loading turntable 2 to rotate ninety degrees counterclockwise, switching the positions of the four clamping and positioning mechanisms 4. Then, the machining tool installed on the spindle at the lower end of the spindle box 102 processes the stator end plate clamped and positioned on the previous and rear clamping and positioning mechanism 4. At the same time, the stator end plate on the clamping and positioning mechanism 4 that has rotated to the left can be removed and replaced. This cycle of operation allows for the loading and unloading of stator end plates while the spindle box 102 is in operation.
