[0032] In this embodiment, as shown in Figure 7 The support block 3 is provided with a circular hole penetrating up and down in the middle, and the positioning rod 4 can slide up and down in the circular hole in the middle of the support block 3.

[0033] In this embodiment, as shown in Figure 7 The support block 3 is provided with a circular hole penetrating up and down in the middle, and the positioning rod 4 can slide up and down in the circular hole in the middle of the support block 3. The positioning rod 4 is also provided with a circular protruding plate on the outside, and the top end of the spring 5 on the outside of the positioning rod 4 is in close contact with the bottom surface of the circular protruding plate. When the bottom surface of the stator core pressing plate 12 is in close contact with the top end of the positioning rod 4, it will push the positioning rod 4 to slide down in the circular hole in the middle of the support block 3, ensuring that the stator core pressing plate 12 can press the stator core silicon steel sheet to be welded tightly. After welding is completed, the electric cylinder 9 can be controlled to extend to push the smoke exhaust pipe 11, the stator core pressing plate 12 and the protective cover 13 to move up to the top again. At this time, the spring 5 on the outside of the positioning rod 4 will push the positioning rod 4 to slide up to the top through the circular protruding plate on the outside of the positioning rod 4, so that the positioning rod 4 is automatically returned to the original position.

[0034] In this embodiment, as shown in Figure 4 and Figure 7 The welding support plate 2 is provided with two rectangular opening grooves penetrating up and down, and the support block 3 can slide left and right in the rectangular opening grooves. The support block 3 is provided with a semicylindrical protruding block on the front and rear outer walls, and the rectangular opening grooves on the welding support plate 2 are provided with a corresponding semicylindrical guide groove on the front and rear sides. When the screw rod 8 rotates, it can drive the support block 3 to slide left and right in the rectangular opening grooves on the welding support plate 2. When the support block 3 slides left and right, the semicylindrical protruding blocks on the front and rear sides will slide left and right in the semicylindrical guide grooves on the inner walls of the rectangular opening grooves on the welding support plate 2, thereby ensuring the stability of the support block 3 when it slides.

[0035] In this embodiment, as shown in Figures 1-3 and Figure 6 and Figure 8As shown, the smoke exhaust pipe 11 is a top open circular pipe, and four circular holes are arranged in the outer wall of the bottom end of the smoke exhaust pipe 11, the protective cover 13 is a transparent glass cover, and a circular hole with the same diameter as the outer diameter of the smoke exhaust pipe 11 is arranged in the middle of the top of the protective cover 13, so that the welding condition can be observed through the protective cover 13 during welding, and the protective cover 13 can rotate outside the smoke exhaust pipe 11, so that the welding of different positions of the stator core can be facilitated, and the exhaust device in the workshop can be opened at the same time, so that the air inside the protective cover 13 is exhausted outside through the smoke exhaust pipe 11, and the smoke generated during welding is also exhausted outside through the circular holes in the outer wall of the bottom end of the smoke exhaust pipe 11, reducing the influence of the smell generated during welding on workers.

[0036] In this embodiment, as shown in the figure, Figure 4 Two protruding blocks are arranged on the bottom of the welding support plate 2, two threaded holes are arranged in the middle of the two protruding blocks, and one end of the two lead screws 8 is rotatably connected to one side of the support block 3, and the threads on the outer sides of the two lead screws 8 are reverse threads. When the lead screws 8 rotate, they will move left and right in the threaded holes in the middle of the protruding blocks on the bottom of the welding support plate 2, and one end of the lead screws 8 will also slide left and right in the cylindrical groove inside the rotating cylinder 7. Therefore, the two support blocks 3 can be driven to slide in the rectangular opening slot on the welding support plate 2 in the opposite direction, and the distance between the two positioning rods 4 can be adjusted to facilitate the positioning of the stator core silicon steel sheets of different sizes.

[0037] In this embodiment, as shown in the figure, Figure 5 The inner diameter of the cylindrical groove inside the rotating cylinder 7 is equal to the outer diameter of the lead screw 8, two semicylindrical protruding blocks are arranged on the outer wall of one end of the lead screw 8, and two corresponding semicylindrical guide grooves are arranged on the inner wall of the rotating cylinder 7. When the rotating cylinder 7 rotates, it will be driven to rotate synchronously by the semicylindrical guide grooves on the inner wall of the rotating cylinder 7 and the semicylindrical protruding blocks on the outer wall of one end of the lead screw 8. When the lead screw 8 rotates, it will move left and right in the threaded holes in the middle of the protruding blocks on the bottom of the welding support plate 2, and one end of the lead screw 8 will also slide left and right in the cylindrical groove inside the rotating cylinder 7, ensuring that the lead screw 8 and the support block 3 can move left and right normally.

[0038] In this embodiment, as shown in the figure, Figures 1-8 Two vertical opening slots are arranged on the outer wall of the protective cover 13, and a layer of rubber is wrapped around the outer wall of the bottom of the protective cover 13. During welding, the welding torch can be inserted through the vertical opening slots on the outer wall of the protective cover 13 to weld the stator core, and the spring 5 outside the smoke exhaust pipe 11 will push the protective cover 13 downward during welding, so that the rubber on the outer wall of the bottom of the protective cover 13 can be tightly attached to the top surface of the welding support plate 2, ensuring that the protective cover 13 can block the smoke generated during welding.

[0039] The working principle of the embodiment: when installing, the device can be supported and fixed on the machining table through the base 1, and the double-shaft motor 6 and the electric cylinder 9 are connected with the external controller and power supply, and the top end of the smoke exhaust pipe 11 is connected with the air inlet of the air exhaust device in the workshop. When the device is needed to weld the motor stator core, first, the silicon steel sheet constituting one of the stator cores is placed on the top of the welding cradle 2, then the double-shaft motor 6 is controlled by the external controller to drive the two rotating cylinders 7 to rotate. When the rotating cylinder 7 rotates, it will drive the screw rod 8 to rotate synchronously by relying on the cooperation between the semicylindrical guide groove on the inner wall of the rotating cylinder 7 and the semicylindrical protruding block on the outer wall of one end of the screw rod 8. When the screw rod 8 rotates, it will move left and right in the threaded hole in the middle of the protruding block at the bottom of the welding cradle 2, and one end of the screw rod 8 will also slide left and right in the cylindrical groove on the inner side of the rotating cylinder 7. Therefore, the supporting block 3 can slide left and right in the rectangular opening slot on the welding cradle 2. When the supporting block 3 slides left and right, the semicylindrical protruding blocks on the front and back sides of the supporting block 3 will slide left and right in the semicylindrical guide grooves on the inner walls of the rectangular opening slot on the welding cradle 2 on the front and back sides, thereby ensuring the stability of the supporting block 3 when it slides. After the supporting block 3 slides left and right, the distance between the two positioning rods 4 can be adjusted, so that the positioning rods 4 can be embedded in the grooves on the inner side of the stator core silicon steel sheet, thereby facilitating the positioning of stator core silicon steel sheets of different sizes. Then, the remaining stator core silicon steel sheets can be placed on the stator core silicon steel sheet in turn. After all the stator core silicon steel sheets are placed, the controller is controlled to drive the two electric cylinders 9 to contract synchronously, thereby driving the upper supporting plate 10 to move down. When the upper supporting plate 10 moves down, the smoke exhaust pipe 11, the stator core pressing plate 12 and the protective cover 13 will move down synchronously. During this process, the bottom surface of the protective cover 13 will first tightly contact the top surface of the welding cradle 2, and then the smoke exhaust pipe 11 and the stator core pressing plate 12 will continue to move down. When the bottom surface of the stator core pressing plate 12 tightly contacts the top end of the positioning rod 4, the positioning rod 4 will be pushed to slide down in the circular hole in the middle of the supporting block 3. Finally, the stator core pressing plate 12 will press the stator core silicon steel sheet tightly, and then a welding torch can be inserted through the vertical opening slot on the outer wall of the protective cover 13 to weld the stator core. During welding, the welding situation can be observed through the protective cover 13, and the protective cover 13 can rotate outside the smoke exhaust pipe 11, thereby facilitating the welding of different positions of the stator core. While welding, the air exhaust device in the workshop can be turned on. At this time, the air exhaust device will exhaust the air inside the protective cover 13 through the smoke exhaust pipe 11, and the smoke generated during welding will also be exhausted through the circular hole on the outer wall of the bottom end of the smoke exhaust pipe 11, thereby reducing the influence of the smell generated during welding on workers. Moreover, the spring 5 outside the smoke exhaust pipe 11 will push the protective cover 13 down during welding, thereby ensuring that the rubber on the outer wall of the bottom of the protective cover 13 tightly contacts the top surface of the welding cradle 2, thereby ensuring that the protective cover 13 can block the smoke generated during welding. After welding is completed, the electric cylinder 9 can be controlled to extend to push the smoke exhaust pipe 11, the stator core pressing plate 12 and the protective cover 13 to move up again to the topmost position.At this time, the spring 5 outside the positioning rod 4 will push the positioning rod 4 up to the topmost position through the circular protruding plate outside the positioning rod 4, so that the positioning rod 4 is automatically returned, and the subsequent positioning of the stator core silicon steel sheet is facilitated.
