A rack 11 is fixedly connected to the movable guide rail of the servo electric cylinder 5 through a connecting plate 12. The rack 11 meshes with the outer gear ring of the external gear slewing support 6. When the movable guide rail of the servo electric cylinder 5 performs telescopic movement, the rack 11 is driven to perform linear movement through the connecting plate 12. The rack 11 is meshed with the outer gear ring of the external gear slewing support 6. When meshing, it will drive the outer gear ring of the external gear rotary support 6 to rotate; a chuck middle cover 2 is fixedly connected to the top of the chuck base 1, and a gear shaft is rotatably connected to the chuck middle cover 2. The number of gear shafts is the same as the number of claws 4, and the number of claws 4 is not less than three. The lower end of the gear shaft meshes with the outer gear ring of the external gear rotary support 6, and a chuck top cover 3 is fixedly connected to the top of the chuck middle cover 2. The chuck top cover 3 is evenly distributed along the circumference with claw slide grooves corresponding to the number of claws 4. The claws 4 are slidably connected in the claw slide grooves and the side walls of the claws 4 are fixedly connected with a toothed plate, which meshes with the upper end of the gear shaft; the rotation of the gear shaft drives the claws 4 to slide, thereby realizing the clamping and loosening of the workpiece by the claws 4.

[0022] Specifically, a chuck pressure block is fixedly connected to the contact point between the inner side of the clamping jaw 4 and the workpiece, and a pressure sensor for collecting the clamping force of the chuck pressure block on the stator of the flat wire motor is fixedly connected to the chuck pressure block. A limit sensing plate is fixedly connected to the outer end of the clamping jaw 4, and the limit sensing plate is slidably connected in the clamping jaw slot. The limit sensing plate is used to limit the stroke of the clamping jaw 4 to prevent the clamping jaw 4 from slipping out of the clamping jaw slot.

[0023] Specifically, the gear shaft is connected to the chuck middle cover 2 and the chuck top cover 3 through the U-shaped bearing seat 10 and the diamond-shaped bearing seat 8.

[0024] Specifically, refer to Figure 4 The gear shaft includes a shaft rod 9 and gears 7 fixedly connected to both sides of the shaft rod, wherein one gear 7 is meshed with the outer gear ring of the external gear slewing support 6, and the other gear 7 is meshed with the gear plate.

[0026] The working principle of this utility model:

[0027] The servo electric cylinder 5 drives the rack 11 on the connecting plate 12 to make linear motion, and the rack 11 meshes with the outer gear ring of the external gear slewing support 6, so that the rack 11 drives the outer gear ring of the external gear slewing support 6 to rotate, and the outer gear ring drives the gear shaft to rotate, and the gear shaft drives the gear plate to move, and the gear plate drives the claw 4 to make linear motion in the claw slide groove. Similarly, the linear motion of each claw 4 is synchronous motion. When the servo electric cylinder 5 makes a feeding motion, each claw 4 moves inward at the same time, so that the claw pressure block contacts the stator core of the flat wire motor. The pressure applied by the claw pressure block to the surface of the stator core of the flat wire motor is fed back by the pressure sensor. When the pressure reaches the preset value, it is considered that the stator of the flat wire motor is clamped, and the servo electric cylinder 5 stops the feeding motion. The outer end of the claw 4 is fixedly connected to a limit position sensor to limit the stroke of the claw 4.
