[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Refer to Figures 1-3, an embodiment provided by the present utility model: a connection device for a coil of an electromagnetic switch device, including a support frame 1. A support column 2 is fixedly connected to the bottom left side of the support frame 1. A support rod 3 is fixed inside the support column 2 through an adjustment component. The adjustment component is used to adjust the height of the support rod 3. The top end of the support rod 3 is fixedly connected to an installation shell 4. A first motor 5 is installed on one side of the outside of the installation shell 4. The output end of the first motor 5 extends into the installation shell 4 and is fixedly connected to a rotating block 6. A plurality of arc-shaped rods 7 are rotatably connected to the outside of the rotating block 6. A plurality of sliding rods 8 are fixedly connected to the inside of the installation shell 4. A slider 9 is slidably connected to the outside of the sliding rod 8. A moving rod 10 is fixedly connected to the outside of the slider 9. The other end of the moving rod 10 is fixedly connected to a clamping block 11. The other ends of the plurality of arc-shaped rods 7 are respectively rotatably connected to the outside of the adjacent slider 9. A plurality of sliding grooves are formed on the outer surface of the installation shell 4. The moving rod 10 is slidably connected to the inside of the sliding groove.
[0025] Specifically, the support frame 1 plays a role in fixing the support column 2, making the support column 2 not prone to tipping over. The support rod 3 is fixed through the adjustment component inside the support column 2, so that the support rod 3 plays a supporting role for the installation shell 4, ensuring that the internal structure of the installation shell 4 will not shake during the clamping operation. By fixing the first motor 5 through the installation shell 4, the first motor 5 can drive the rotating block 6 to rotate after starting, and then the arc-shaped rod 7 rotates. The arc-shaped rod 7 can drive the slider 9 to slide along the sliding rod 8, making the moving rod 10 move, and driving the clamping block 11 to move, so that the plurality of clamping blocks 11 approach the center, realizing the clamping and fixing of the electromagnetic switch device, making it not shake when connected to the coil, ensuring the firmness of welding, and avoiding the occurrence of poor contact. The plurality of sliding grooves respectively play a role in restricting the movement of the plurality of moving rods 10.
[0026] Referring to Figure 4 and Figure 5 , the adjustment component includes a limiting groove 19 opened inside the support column 2. A spring 20 is fixedly connected to the inside of the limiting groove 19. The other end of the spring 20 is fixedly connected to a limiting block 21. A pull rod 22 is fixedly connected to one side of the limiting block 21. A clamping block 23 is fixedly connected to the other side of the limiting block 21. A plurality of clamping grooves 24 are opened on the side of the support rod 3 close to the pull rod 22. The limiting block 21 is slidably connected to the inside of the limiting groove 19. The spring 20 is sleeved on the outside of the pull rod 22. The clamping block 23 and the clamping groove 24 are in plug-in fit.
[0027] Specifically, by pulling the pull rod 22, the pull rod 22 drives the limit block 21 to slide inside the limit slot 19, and the limit slot 19 restricts the movement of the limit block 21 to ensure that the limit slot 19 can maintain horizontal movement. While compressing the spring 20, it can also drive the latch 23 to disengage from the card slot 24, thereby adjusting the height of the support rod 3 extending out, making the height of the fixed electromagnetic switch device match that of the coil, facilitating connection, and improving the flexibility of the device. After the support rod 3 is adjusted to an appropriate height by the spring 20, when the pull rod 22 is released, the spring 20 will release elastic potential energy to push the limit block 21 to move, and then the latch 23 and the card slot 24 will complete the plug-in fit to fix the position of the support rod 3.
[0028] Refer to Figure 2 As shown in the figure, a second motor 12 is installed on the right side of the top of the support frame 1. The output end of the second motor 12 is fixedly connected to a threaded rod 13. A threaded block 14 is threadedly connected to the outside of the threaded rod 13. A moving block 15 is fixedly connected to the top of the support frame 1. A guide rod 16 is slidably connected to the outside of the moving block 15. The bottom of the threaded block 14 and the guide rod 16 are fixedly connected to a moving plate 17. The bottom of the moving plate 17 is fixedly connected to a clamping cylinder 18.
[0029] Specifically, the operation of the second motor 12 can drive the threaded rod 13 to rotate, thereby causing the threaded block 14 to move. At the same time, the moving block 15 will slide along the guide rod 16, which can play a guiding role in the movement of the threaded block 14. Thus, under the cooperation of the threaded block 14 and the moving block 15, the moving plate 17 is driven to move, and the clamping cylinder 18 is driven to move. The coil can be clamped and fixed by the clamping cylinder 18, and then it can be close to the fixed electromagnetic switch device, facilitating the connection between the two and ensuring the stability of the connection.
[0030] Refer to Figure 4 As shown in the figure, the outside of the support rod 3 is slidably connected to the inside of the support column 2. A plurality of card slots 24 are evenly opened on one side of the support rod 3.
[0031] Specifically, the sliding connection between the support rod 3 and the support column 2 facilitates the height adjustment of the support rod 3, thereby changing the height of the installation shell 4. And the plurality of card slots 24 can improve the flexibility of adjustment, providing more choices.
[0032] Working principle: When using this device, starting the first motor 5 can drive the rotating block 6 to rotate, thereby causing the multiple arc-shaped rods 7 connected to the outside to move, which can drive the slider 9 to slide along the slide rod 8, causing the moving rod 10 to move, so that the multiple clamping blocks 11 move closer to the center, realizing the clamping and fixing of the electromagnetic switch device, ensuring that there is no shaking when connected to the coil, ensuring the firmness of welding, and avoiding the occurrence of poor contact. Then, the operation of the second motor 12 drives the threaded rod 13 to rotate, thereby causing the threaded block 14 to move. At the same time, the moving block 15 will slide along the guide rod 16, playing a guiding role in the movement of the threaded block 14, so as to drive the moving plate 17 to move, and then drive the clamping cylinder 18 to move, so that the coil clamped by the clamping cylinder 18 can approach the fixed electromagnetic switch device, facilitating the connection between the two, ensuring the stability of the connection. At the same time, by pulling the pull rod 22, the pull rod 22 can drive the limit block 21 to slide inside the limit groove 19. While compressing the spring 20, it can drive the latch 23 to disengage from the card slot 24, so as to adjust the height of the support rod 3 extending, making the height of the fixed electromagnetic switch device match that of the coil, facilitating the connection and improving the flexibility of the device.
[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
