Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0023] Example:
[0024] See also Figures 1-4 , the utility model provides a technical solution:
[0025] The tension adjustment device for the production of motor enameled wire includes a fixed platform 1, the four corners of the bottom of the fixed platform 1 are fixedly connected to support feet 2, the fixed platform 1 is fixedly connected to a support platform 3, the bottom end of the support platform 3 is fixedly connected to a reinforcing strip, the top of the support platform 3 is fixedly connected to a partition 4, the outer side of the partition 4 is rotatably connected to a first drive wheel 5, the back side of the partition 4 is fixedly connected to a connecting plate 6, the inner side of the connecting plate 6 is rotatably connected to a second drive wheel 7, an arc groove 8 is provided in the middle of the partition 4, the inner side of the arc groove 8 is slidably connected to a guide roller 9, the outer side of the guide roller 9 is fixedly connected to a rectangular box 10, and the outer side of the rectangular box 10 is rotatably connected to an adjusting wheel 11, through The supporting foot 2 is placed on the ground, so that the fixed platform 1 is kept in a horizontal and vertical state with the ground, and the supporting platform 3 is also stable. The enameled wire is placed on the outside of the first driving wheel 5 and the second driving wheel 7 respectively, and the enameled wire between the first driving wheel 5 and the second driving wheel 7 is passed through the bottom of the adjusting wheel 11. When the tension of the enameled wire needs to be adjusted, the rectangular box 10 is moved by turning the adjusting wheel 11, and the movement force is transmitted to the guide roller 9, and the arc groove 8 limits the guide roller 9, so that the guide roller 9 slides inside the arc groove 8, and then the pressure of the adjusting wheel 11 on the enameled wire is realized to achieve tension adjustment.
[0026] Furthermore, in this embodiment, a limit block 12 is fixedly connected to the middle of the guide roller 9, a linkage rod 13 is fixedly connected to the side of the guide roller 9 away from the rectangular box 10, and a rotating shaft 14 is fixedly connected to the side of the linkage rod 13 away from the guide roller 9. By rotating the rotating shaft 14, the linkage rod 13 is swung, and then the guide roller 9 is moved, and the rectangular box 10 and the limit block 12 are respectively arranged on both sides of the partition 4, so that the guide roller 9 is wrapped and fits with the partition 4.
[0027] Furthermore, in this embodiment, a control box 15 is fixedly connected to the outside of the rotating shaft 14, and a guide plate 16 is rotatably connected to the inside of the control box 15 and located outside the rotating shaft 14. An extension frame is fixedly connected to the bottom of the control box 15, and a worm 17 is rotatably connected to the inside of the extension frame. The outside of the worm 17 is meshed with a worm wheel 18, and the inside of the worm wheel 18 is rotatably connected to an insertion shaft. A rotating plate 19 is fixedly connected to the side of the insertion shaft away from the worm wheel 18, and a synchronization rod 20 is rotatably connected between the rotating plate 19 and the guide plate 16. By rotating the worm 17, the worm wheel 18 will mesh with the worm 17, so that the worm wheel 18 rotates, and then the rotating plate 19 and the worm wheel 18 rotate synchronously. The synchronization rod 20 will rotate along with the rotating plate 19, and at the same time generate a pulling force on the guide plate 16 to realize the rotation of the rotating shaft 14.
[0028] Furthermore, in this embodiment, a waist groove is opened on the surface of the rectangular box 10, and the internal rotation of the adjusting wheel 11 is connected to a connecting shaft, which extends to the interior of the rectangular box 10 through the waist groove. When the first driving wheel 5 and the second driving wheel 7 rotate, a conveying force is generated. After the adjusting wheel 11 comes into contact with the enameled wire, it drives the adjusting wheel 11 to rotate synchronously, thereby greatly improving the smoothness of the conveying process.
[0029] Furthermore, in this embodiment, the interior of the rectangular box 10 is fixedly connected to a support rod 21, and the support rod 21 is symmetrically slidably connected to a slider 22. A spring 23 is provided on the outside of the support rod 21 and on the side away from the slider 22. The top of the slider 22 is rotatably connected to a swing rod, and the end of the swing rod away from the slider 22 is rotatably connected to a mounting seat 24. A slot is provided in the interior of the mounting seat 24 at a position corresponding to the connecting shaft. A buffer block 25 is fixedly connected to the middle of the outside of the support rod 21. During the transportation of the enameled wire, the enameled wire is wound around the first driving wheel 5 and the second driving wheel. 7, when the position changes, the enameled wire will pull the adjusting wheel 11 upward when subjected to tension, so that the connecting shaft drives the mounting seat 24 to move upward, and then the swing arms are brought closer to each other, and at the same time, the spring 23 is pulled to stretch, thereby generating a buffering capacity, thereby achieving the purpose of adaptively adjusting the tension following the position change of the enameled wire, and effectively preventing the enameled wire from being broken by a strong tensile force. When the tension disappears, the spring 23 is reset, so that the mounting seat 24 moves downward, and at the same time, the buffer block 25 removes the impact force between the mounting seat 24 and the support rod 21, thereby extending its service life.
[0030] In this embodiment, the implementation scenario is specifically as follows: by placing the supporting foot 2 on the ground, the fixed platform 1 is kept in a horizontal and vertical state with the ground, and the supporting platform 3 is also stable, by placing the enameled wire on the outside of the first driving wheel 5 and the second driving wheel 7 respectively, and passing the enameled wire between the first driving wheel 5 and the second driving wheel 7 through the bottom of the adjusting wheel 11, when the tension of the enameled wire needs to be adjusted, the worm 17 is rotated, and then the worm wheel 18 is engaged with the worm 17, so that the worm wheel 18 rotates, and then the rotating plate 19 and the worm wheel 18 rotate synchronously, and the synchronization rod 20 rotates with the rotating plate 19, and at the same time generates tension on the guide plate 16, so that the rotating shaft 14 rotates, and the linkage rod 13 swings, and then the guide roller 9 moves, and the arc The groove 8 will limit the guide roller 9, so that the guide roller 9 can slide inside the arc groove 8, and then the pressure of the adjusting wheel 11 on the enameled wire can be realized to realize tension adjustment. When the enameled wire changes its position when it is wound on different positions of the first driving wheel 5 and the second driving wheel 7, the enameled wire will pull the adjusting wheel 11 upward when it is subjected to tension, so that the connecting shaft drives the mounting seat 24 to move upward, and then the swing bars are brought closer to each other, and at the same time, the spring 23 is pulled to stretch, thereby generating buffering capacity, achieving the purpose of adaptively adjusting the tension following the position change of the enameled wire, and can effectively prevent the enameled wire from being broken by a strong tensile force. When the tension disappears, the spring 23 is reset, so that the mounting seat 24 moves downward, and at the same time the buffer block 25 removes the impact force between the mounting seat 24 and the support rod 21, thereby extending its service life.
