DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example: like Figure 1-9 As shown, this embodiment proposes a stator winding device for producing a servo motor, comprising a cabinet 10, on which a rotating shaft 13 is provided; An elastic reset component 80 is provided on the rotating shaft 13, and a movable frame 20 that can be moved back and forth is also provided on the side of the cabinet 10. The movable frame 20 matches the position of the elastic reset component 80. A placement plate 70 is provided on the movable frame 20 and the elastic reset component 80. A silicon steel sheet rack module 60 is provided between the two groups of the placement plates 70. The movable frame 20 is displaced toward the cabinet 10, so that the two groups of placement plates 70 clamp the silicon steel sheet rack module 60 to perform the winding process.

[0020] In this case, the silicon steel sheet rack module 60 is a part of the servo motor stator. After the winding of multiple sets of silicon steel sheet rack modules 60 is completed, the multiple sets of silicon steel sheet rack modules 60 are combined together and welded to form a completed servo motor stator. In this embodiment, when the silicon steel sheet rack module 60 is wound, the silicon steel sheet rack module 60 is placed between two sets of placement plates 70, and the placement plates 70 away from the cabinet 10 are driven by the moving frame 20 to move until the two sets of placement plates 70 contact the silicon steel sheet rack module 60, and then a circle of guide is wound around the grooves on both sides of the silicon steel sheet rack module 60, and the rotating shaft 13 is rotated at the same time, so that the silicon steel sheet rack module 60 is rotated to perform the winding process; The automated stator winding device can realize a fast and continuous winding process, reducing the time and labor intensity of manual operation, thereby improving the production efficiency of the servo motor stator; The position of the placement plate 70 can be accurately controlled by the moving frame 20 and the elastic reset assembly 80 to ensure the precise positioning of the silicon steel sheet rack module 60 during the winding process, thereby ensuring the uniformity and accuracy of the winding; The clamping, winding and releasing processes of the silicon steel sheet rack module 60 are automatically completed by the mobile frame 20, which reduces manual intervention, improves the degree of automation of production, reduces labor costs and material waste, and helps to reduce the production cost of the servo motor.

[0021] Specifically, the cabinet 10 is provided with a guide rod 40, and the guide rod 40 is connected to the surface of the cabinet 10; A movable rod 30 is arranged just above the guide rod 40 , and the movable rod 30 is rotatably arranged on the cabinet 10 . The movable frame 20 is connected to a placement plate 70 away from the cabinet 10 , and the movable frame 20 cooperates with the movable rod 30 and the guide rod 40 to move back and forth.

[0022] Specifically, the surface of the movable rod 30 is provided with an external thread wall 31; The movable frame 20 is provided with a threaded sleeve 21 and a guide sleeve 22 . The threaded sleeve 21 is threadedly sleeved on the external threaded wall 31 , and the guide sleeve 22 is slidably sleeved on the outer wall of the guide rod 40 .

[0023] In this embodiment, when the movable frame 20 needs to move toward the cabinet 10, the movable rod 30 rotates, and the cooperation between the external thread wall 31 and the threaded sleeve 21 causes the movable frame 20 to move along the axial direction of the movable rod 30 to adjust the position of the movable frame 20; Of course, the sliding fit between the guide sleeve 22 and the guide rod 40 can improve the stability of the movable frame 20 during displacement.

[0026] Specifically, the elastic reset assembly 80 includes a reset circular plate 81, on which a reset rod 84 is coaxially arranged, on which a reset hexagonal prism 85 is arranged, and the outer wall sliding sleeve of the reset hexagonal prism 85 is provided with a reset sleeve 86, and the reset sleeve 86 is connected to the placement plate 70 close to the cabinet 10.

[0027] Specifically, a reset spring 82 is disposed on the reset circular plate 81 . The reset spring 82 is sleeved on the outer wall of the reset rod 84 . The reset spring 82 is also connected to the placement plate 70 close to the cabinet 10 .

[0028] In this embodiment, when the moving frame 20 is displaced, the moving frame 20 drives a group of placement plates 70 away from the cabinet 10 to move toward the cabinet 10. When clamping the silicon steel sheet rack module 60, the moving frame 20 continues to displace, so that the reset sleeve 86 is displaced on the reset hexagonal prism 85, thereby causing the two groups of placement plates 70 and a group of silicon steel sheet rack modules 60 to be displaced along the axis of the reset rod 84. At this time, the reset spring 82 is in a compressed state, so that on the basis of clamping, the position of the silicon steel sheet rack module 60 can be adjusted, and winding processing can be performed on different positions of the grooves on both sides of the silicon steel sheet rack module 60.

The fixing rod 83 is connected to a set of placement plates 70 close to the cabinet 10 , and a bolt is provided at one end of the fixing rod 83 facing the cabinet 10 .

[0030] In this embodiment, the fixing rod 83 is slidably arranged in the fixing through hole 90, so that the stability of the silicon steel sheet rack module 60 during the displacement process can be ensured.

[0031] Specifically, two groups of side plates 73 are provided on the placement plate 70 , two groups of placement screws 71 are threadedly provided on the side plates 73 , a clamping plate 72 is provided between the two groups of the placement screws 71 , and the placement screws 71 are rotatably connected to the clamping plate 72 .

[0032] In this embodiment, by means of the threaded cooperation between the placement screw 71 and the side plate 73, the clamping plate 72 can be displaced toward the silicon steel sheet rack module 60, and the silicon steel sheet rack module 60 can be reinforced by two sets of clamping plates 72 to ensure the stability of the silicon steel sheet rack module 60 during the winding process.

[0033] Specifically, a connecting plate 50 is provided on the cabinet 10 , and a connecting guide pipe 51 is provided on the connecting plate 50 . The connecting guide pipe 51 matches the position of the silicon steel sheet rack module 60 .

[0034] In this embodiment, when winding the silicon steel sheet rack module 60, the wire is passed through the connecting guide tube 51 and first wrapped around the grooves on both sides of the silicon steel sheet rack module 60. Then, the silicon steel sheet rack module 60 is rotated to perform the winding process. When the moving frame 20 pushes the silicon steel sheet rack module 60 to move, the connecting guide tube 51 points to different positions of the grooves on both sides of the silicon steel sheet rack module 60, so as to perform the winding process on different positions of the grooves on both sides of the silicon steel sheet rack module 60.
