Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on the present application. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0023] like Figure 1-4 As shown, a flat wire motor stator crimping machine includes a workbench 16, a support frame 19 is installed on the workbench 16, a first motor 20 is installed on the top of the support frame 19, and a first gear 21 is installed at the output end of the first motor 20.

[0024] A ball screw 23 is installed on the top of the support frame 19, and the nut of the ball screw 23 is rotatably connected to the support frame 19. The nut fixing sleeve of the ball screw 23 is provided with a second gear 1. The screw 3 of the ball screw 23 passes through the top of the support frame 19 and is fixedly connected to a pressing plate 5. A chain 22 is installed between the first gear 21 and the second gear 1. The first motor 20 can drive the second gear 1 to rotate through the first gear 21 and the chain 22, and the second gear 1 drives the nut of the ball screw 23 to rotate.

[0025] The output end of the screw 3 is fixedly connected with a pressing plate 5, and the pressing plate 5 is slidably connected with a plurality of guide rods 4, and the guide rods 4 are vertically fixedly connected to the support frame 19, and the pressing plate 5 is concave; the pressing plate 5 includes a pressing portion 24 and a limiting portion 26, and a connecting portion 25 is installed on the top of the lower pressing plate 24, and the lower pressing portion 24 and the limiting portion 26 are fixedly connected through the connecting portion 25. A plurality of guide rods 4 are installed on the top of the support frame 19, and the guide rods 4 penetrate the limiting portion 26. The guide rods 4 are light rods that limit the direction of the pressing plate 5, so that the pressing plate 5 can only move up and down along the guide rods 4. At the same time, the guide rods can prevent the pressing plate 5 from rotating, and the pressing plate 5 is fixedly connected to the screw, and the screw 3 also does not rotate. Therefore, when the nut of the ball screw 23 rotates, the screw 3 will drive the pressing plate 5 to move up and down, thereby realizing the pressing and multi-movement of the pressing plate 5.

[0026] The guide rod 4 is slidably connected to the limit portion 26, and the guide rod 4 can limit the pressing plate 5 from rotating, so that the screw rod 3 can move up and down when the sleeve 23 rotates, so that the pressing plate 5 can move along the guide rod 4, thereby completing the pressing action of the pressing plate 5 and the lifting action after the pressing is completed; the concave shape of the pressing plate 5 can shorten the required length of the guide rod 4.

[0027] A connecting rod 6 is installed at the bottom of the guide rod 4, and the connecting rod 6 is vertically arranged to the guide rod 4. The connecting rod 6 is fixedly connected to the support frame 19. The connecting rod 6 can make the structure of the guide rod 4 more stable, and prevent the screw 3 from driving the pressing plate 5 to move up and down, so that the pressing plate 5 can cause the guide rod 4 to tilt or even directly break the guide rod 4. The concave shape of the pressing plate 5 can shorten the required length of the guide rod 4 and prevent the pressing plate 5 from affecting the handling of the stator of the flat wire motor during the downward pressing process.

[0028] A tripod 15 is installed on the top of the workbench 16, and a second motor 11 is installed on the tripod 15. The tripod 15 supports the second motor 11 and can make the structure of the device on the workbench 16 more stable during work. A third gear 12 is installed on the output end of the second motor 11, and the third gear 12 is meshingly connected with a fourth gear 13. A transmission shaft 10 is installed on the fourth gear 13. The transmission shaft 10 passes through the workbench 16 and is installed with a base 9. The second motor 11 drives the third gear 12 to rotate, the third gear 12 drives the fourth gear 13 to rotate, the fourth gear 13 drives the transmission shaft 10 to rotate, and the transmission shaft 10 drives the base 9 to rotate; the base 9 is a rectangle with arc treatment at both ends, and two installation barrels 18 with the transmission shaft 10 as the central symmetry point are symmetrically installed on the base 9, and the installation barrel 18 is used to place the flat wire motor that needs to be pressed. Stator, by setting the operation cycle of the second motor 11, the second motor 11 can rotate the base 9 180° each time it runs. When the base 9 is in the initial position, one of the mounting barrels 18 corresponds to the screw rod 3 up and down. In this way, the second motor 11 can be controlled to operate after each pressing is completed, so that the other mounting barrel 18 rotates to a position corresponding to the screw rod 3 up and down. During each pressing process, the flat wire motor stator to be pressed is placed on the mounting barrel 18 that does not correspond to the screw rod 3 up and down, and the control dial moves the mounting barrel 18 corresponding to the flat wire motor stator to be pressed to the position corresponding to the screw rod 3 up and down, and presses. During the pressing process, other flat wire motor stators are placed on the empty mounting barrel 18. After pressing is completed, the chassis is rotated to change the position of the mounting barrel 18, and the pressing continues. At the same time, the flat wire stator that has been pressed is removed, and a new flat wire motor stator to be pressed is placed on the mounting barrel 18.

[0029] A limit block 17 is installed on the workbench 16, and the limit block 17 is installed in cooperation with the base 9. The limit block 17 and the base 9 are slidably connected, and the position of the limit block 17 and the screw rod 3 are arranged correspondingly up and down. Since there is a certain gap between the base 9 and the work, during the pressing process, the force on the base 9 is uneven, and the pressure of the pressing plate 5 is relatively large, which may cause the base 9 to tilt during the pressing process, and may also affect the normal operation of the transmission shaft 10. The limit block 17 can prevent the base 9 from tilting too much, and plays a role in limiting the side of the base 9 that is subjected to force.

[0030] The workbench 16 is provided with a fixing device 7, which is matched with the arc-shaped end of the base 9 and is located on a side away from the screw rod 3. The fixing device 7 can fix the base 9 to prevent the base 9 from being rotated by manual external force applied during installation or removal of the flat wire motor stator; the fixing device 7 includes a surrounding platform 27, which is fixedly connected to the workbench 16, and is C-shaped. The bottom of the surrounding platform 27 is slidably connected to the base 9, and there is a certain distance between the top of the surrounding platform 27 and the top of the base 9. A cylinder 28 is installed on the top of the surrounding platform 27, and a fixing plate 29 is installed on the output end of the cylinder 28. The fixing plate 29 is located between the top of the surrounding platform 27 and the top of the base 9. When fixing is required, the cylinder 28 is controlled to extend and retract downward, so that the fixing plate 29 and the bottom of the surrounding platform 27 squeeze the base 9, thereby fixing the base 9.

[0031] A controller 8 is installed on one side of the workbench 16 , and the controller 8 is electrically connected to the first motor 20 , the second motor 11 and the cylinder 28 . The controller 8 makes the control of the entire device more convenient and concise.

[0032] To sum up, in actual use, the flat wire motor stator must first be placed in the corresponding mounting barrel 18, and then the mounting barrel 18 is controlled to move to directly below the screw 3, and then the cylinder 28 is controlled to fix the base 9, and then the first motor 20 is controlled to rotate so that the pressing plate 5 presses the flat wire motor stator downward. While pressing, another flat wire motor stator can be placed on another mounting barrel 18. After the pressing is completed, the first motor 20 is controlled to make the pressing plate 5 rise back to the initial position, the fixing device 7 is controlled to release, and then the base 9 is rotated for pressing.

[0033] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
