DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0022] As Figure 1 - Figure 4As shown, a motor winding machine with a limiting function includes a winding head 1 and a worktable 2. The winding head 1 is located above the worktable 2. Several support platforms 3 are mounted on the top of the worktable 2, and the winding head 1 is located directly above the support platform 3. Each support platform 3 has a top groove 4 on its top, and a working cavity is formed inside the support platform 3. The top groove 4 communicates with the working cavity. Two clamping claws are slidably connected in the top groove 4. The clamping claws include a drive rod 5, a base plate 6, a worm gear 7, two side worm wheels 8, two rotating plates 9, two moving rods 10, two swing rods 11, and two side panels 12. The two side panels 12 are respectively fixedly mounted on the two side walls of the base plate 6. A fixing seat 13 is formed at the bottom of the base plate 6. The drive rod 5 passes through the fixed seat 13, the worm gear 7 is fixedly mounted on the top of the drive rod 5, the two rotating plates 9 are respectively fixedly connected to the side walls of the two side worm wheels 8, the side worm wheels 8 are rotatably connected to the side walls of the side panel 12, the two side worm wheels 8 are respectively threadedly connected to the worm gear 7, the two swing rods 11 are respectively rotatably connected to the side walls of the two side panels 12, the swing rod 11 is rotatably connected to the side panel 12 at the top of the side panel 12, the swing rod 11 is rotatably connected to the moving rod 10 at the middle position of the moving rod 10, when the moving rod 10 is driven to move, the swing rod 11 will restrict the moving rod 10, thereby causing the arc-shaped clamp 14 at the end of the moving rod 10 to clamp the stator.

[0023] The other end of the swing rod 11 is rotatably connected to the side wall of the moving rod 10. One end of the moving rod 10 is rotatably connected to the end of the rotating plate 9 away from the side worm gear 8. An arc-shaped clamping plate 14 is installed at the end of the moving rod 10 away from the rotating plate 9. The top of the arc-shaped clamping plate 14 is flat to better clamp the edge of the stator, while the lower end of the arc-shaped clamping plate 14 is arc-shaped. When the arc-shaped clamping plate 14 releases the stator, the stator will fall onto the side panel 12 under the guidance of the arc-shaped part of the arc-shaped clamping plate 14, ensuring that the stator will not be damaged due to sudden falling.

[0024] A drive mechanism for driving the gripper is installed in the working cavity. The drive mechanism includes a dual-axis motor 15, a telescopic spring 16, two threaded rods 17, two moving blocks 18, and two side rods 19. A transverse groove 20 is formed in the side wall of the working cavity. The two side rods 19 are slidably connected to the transverse groove 20. The telescopic spring 16 is fixedly disposed between the two side rods 19. The dual-axis motor 15 is located in the working cavity. The two output ends of the dual-axis motor 15 are fixedly connected to the two threaded rods 17, respectively. The two moving blocks 18 are threadedly connected to the two threaded rods 17, respectively. The thread directions of the two threaded rods 17 are opposite. Therefore, when the dual-axis motor 15 drives the two threaded rods 17 simultaneously, the moving blocks 18 will simultaneously move towards or away from the dual-axis motor 15. The drive rod 5 passes through the top of the moving block 18. Figure 4 As can be seen, the two ends of the moving block 18 are designed with arcs to fit the arcs at the ends of the top groove 4.

[0025] The movement cavity is arranged in the movement block 18, and a rotating mechanism matched with the side rod 19 is arranged in the movement cavity, the rotating mechanism comprises an electric push rod 21, a center rod 22, two side racks 23, two connecting gears 24 and two rotating gears 25, the electric push rod 21 is arranged in the working cavity, the output end of the electric push rod 21 is fixedly connected with the side wall of the center rod 22, the side wall of the side rod 19 is provided with a movement groove 26, the two ends of the center rod 22 respectively pass through the two movement grooves 26, the movement groove 26 is in a T shape, and the center rod 22 is also in a T shape; the arrangement of the movement groove 26 and the center rod 22 enables the center rod 22 to always keep the driving effect on the side rod 19 when the two movement blocks 18 move relative to each other.

[0026] The side rack 23 is fixedly arranged on the side wall of the side rod 19, the side rod 19 passes through the side wall of the movement block 18, the connecting gear 24 and the rotating gear 25 are rotationally connected with the side wall of the movement cavity, the side rack 23 is meshed with the connecting gear 24, the rotating gear 25 is meshed with the side, away from the side rack 23, of the connecting gear 24, the size of the rotating gear 25 is greater than that of the connecting gear 24, but the meshing state can still be ensured, the driving rod 5 is fixedly connected with the top of the rotating gear 25, and the size of the rotating gear 25 is greater than that of the connecting gear 24, so that the rotating gear 25 can drive the driving rod 5 to rotate.

[0027] The working principle is as follows: firstly, the double-shaft motor 15 is driven, so that the two threaded rods 17 rotate, the movement block 18 arranged on the threaded rod 17 moves along the top groove 4, so that the distance between the two clamping jaws is consistent with the diameter of the stator to be wound, then the stator is placed in the middle position of the two arc-shaped clamping plates 14, the electric push rod 21 is driven, so that the center rod 22 drives the side rod 19 to move, the side wall gear fixedly arranged on the side wall of the side rod 19 drives the connecting gear 24 to rotate, thereby the rotating gear 25 meshed with the connecting gear 24 rotates synchronously, so that the driving rod 5 arranged on the top of the rotating gear 25 rotates along with the rotating gear 25;

[0028] The driving rod 5 drives the worm 7 to rotate, the side worm gears 8 arranged on the two sides of the worm 7 drive the rotating plate 9 to rotate, thereby the movement rod 10 moves obliquely downward, the swing rod 11 inclines when the movement rod 10 moves, thereby the arc-shaped clamping plate 14 at the end of the movement rod 10 clamps the side wall of the stator, so that the winding head 1 conveniently winds the stator.

[0029] The above merely describes a preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
