As shown in fig. 2, the outer rotating ring 1 is cylindrical in shape and has a plurality of driving grooves 8 on its side wall. The driving groove 8 penetrates through the side wall of the outer rotating ring 1, one end of the driving groove is higher, the other end of the driving groove is lower, and the driving groove is obliquely arranged.
The inner annular plate 2 can be vertically arranged inside the outer rotating ring 1 in a sliding mode, and the inner annular plate 2 and the outer rotating ring 1 are coaxially arranged.
As shown in fig. 3, the outer wall of the inner annular plate 2 is provided with a plurality of driving shafts 9, and each driving shaft 9 is disposed in one of the driving grooves 8. The number of the driving shafts 9 is set to be plural, and is specifically the same as the number of the driving grooves 8, and each driving shaft 9 is inserted into one driving groove 8.
The shape of the drive shaft 9 is adapted to the shape of the drive slot 8 so that the drive shaft 9 is movable along the drive slot 8. Typically, the driving slot 8 is a strip-shaped slot with a constant width, such as an oblong slot, and the width of the driving slot 8 is equal to the diameter of the driving shaft 9. The driving shaft 9 may be a pin or a roller.
When the outer rotating ring 1 rotates, the driving groove 8 synchronously rotates, and then the driving shaft 9 is lifted or lowered, so that the inner annular plate 2 is lifted and lowered. In order to ensure that the inner annular plate 2 is stably lifted or lowered, the driving grooves 8 are uniformly distributed along the circumferential direction of the outer rotating ring 1, and the driving shafts 9 are uniformly distributed on the outer wall of the inner annular plate 2.
The fixing ring 3 is fixedly arranged, is positioned inside the inner annular plate 2 and is coaxially arranged with the inner annular plate 2.
The number of the clamping members 4 is set to be plural, and the number can be flexibly determined according to the number of the groups of the coil heads 101 of the stator 100 in practical application, and generally can be kept consistent with the number of the groups of the coil heads 101. As shown in fig. 3, in the present embodiment, the number of the groups of the stubs 101 of the stator 100 is 48, and each group includes 4 stubs 101 arranged along the radial direction of the stator 100, so that the number of the clamping members 4 is set to be 48.
As shown in fig. 4, the clamping members 4 are uniformly distributed around the axis of the fixing ring 3, and each clamping member 4 comprises a rack 13, a gear 12 and a clamping jaw 14.
A plurality of clamping teeth 17 arranged at intervals are arranged on one side of the clamping jaw 14, an inclined abutting surface 18 is arranged on the other side of the clamping jaw, the rack 13 is vertically fixed on the inner annular plate 2, the middle part of the clamping jaw 14 rotatably penetrates through the fixing ring 3, and the rear end of the clamping jaw is connected with the gear 12.
Preferably, as shown in fig. 5 and 6, each of the jaws 14 includes a connecting rod 15 and a clamping head 16 connected to each other, and the connecting rod 15 is horizontally arranged, and the middle part of the connecting rod penetrates through the fixing ring 3 and can rotate.

The clamping teeth 17 are arranged on one side of the chuck 16 at equal intervals. The abutting surface 18 is arranged on the other side of the chuck 16. Preferably, the abutting surface 18 of the chuck 16 is a cambered surface. A groove 19 is formed between two adjacent clamping teeth 17, and the groove bottom of each groove 19 is parallel to the abutting surface 18 of the adjacent clamping head 16.
When the wire ends 101 are clamped through the stator wire end integral clamping device of the flat wire motor, in an initial state, the stator 100 is clamped and fixed inside the fixing ring 3 and located at a preset position, the wire ends 101 face and are flush, each clamping piece 4 is located between two adjacent groups of wire ends 101 in the circumferential direction, the front end of each clamping head 16 extends to the inner ring of the stator 100, and each clamping head 16 is in a vertical state.
Then, the outer rotating ring 1 is driven to rotate, the driving groove 8 synchronously rotates to drive the inner annular plate 2 to lift, and then each rack 13 is driven to move upwards, and the gear 12 and the rack 13 are meshed for transmission to enable the chuck 16 to rotate to a horizontal state. As shown in fig. 7, the respective ends 101 of each group of coils enter the respective recesses 19, and since the groove bottoms of the respective recesses 19 are parallel to the abutting surface 18 of the adjacent chuck 16, the respective ends 101 of each group of coils are clamped by the respective clamping teeth 17 of each clamping jaw 14 and the abutting surface 18 of the adjacent clamping jaw 14.
Because each thread end 101 enters each groove 19, the abutting surface 18 blocks the notch direction of the groove 19, so that each clamping tooth 17 of each clamping jaw 14 and a plurality of constraint spaces formed by the abutting surface 18 of an adjacent clamping jaw 14 perform accurate circumferential and radial positioning on each thread end 101, and accurate positioning of all the clamped thread ends 101 is ensured.
It should be noted that, even if the partial thread ends 101 have a position offset, especially a circumferential offset, before being clamped, under the pushing action of the abutting surface 18, the position of the thread ends 101 can be adjusted, so that each thread end 101 can accurately enter each groove 19, thereby ensuring that the thread ends 101 can be clamped at the same time.
In some other embodiments, the stator wire end integral clamping device of the flat wire motor further comprises a workbench 5 and a rotating disk 10.
The middle of the workbench 5 is provided with a through hole, the diameter of the through hole is larger than the outer diameter of the stator 100, the stator 100 to be welded is placed in the through hole, the rotary disk 10 surrounds the through hole and is arranged on the workbench 5, the edge of the rotary disk 10 is connected with the outer rotating ring 1, the edge of the rotary disk 10 is in transmission with the outer rotating ring 1, and the outer rotating ring 1 can be driven to rotate.

In this embodiment, the stator clamp 6 surrounds the through hole and is installed below the table 5. After the stator 100 is clamped by the stator clamp 6, the thread end 101 of the stator 100 is in an upward flush state.
Since the stator clamp 6 is a common device in the flat wire motor stator production line, and its function is only to clamp the iron core of the stator 100 by the periphery, the stator clamp 6 will not be explained in detail here.
The lifting mechanism is connected with the stator clamp 6 to drive the stator to lift, and the lifting mechanism can select a cylinder or a lead screw. The lifting mechanism drives the stator clamp 6 to be lifted when each wire end 101 needs to be clamped, so that the stator 100 reaches a preset height, and drives the stator clamp 6 to be lowered after each wire end 101 is welded, so that the stator 100 is lowered, and the welded stator 100 is taken out.
