Description

Technical Field

[0001] This application relates to the field of capacitor assembly clamping technology, specifically a clamping fixture for capacitor assembly and welding. Background Technology

[0002] The clamping fixture for capacitor assembly and welding is a fixture or platform specifically designed for the capacitor welding process, aiming to improve the accuracy and efficiency of welding.

[0003] In the existing capacitor assembly and fixing process, positioning pins are usually used to limit the copper busbar and capacitor core, and a clamping device (such as the clamping device in the patent with publication number CN211042007U) is used to clamp the copper busbar and capacitor core.

[0004] However, due to the different application scenarios, the capacitor cores have different sizes. In order to maintain smooth communication between the capacitor cores, the copper busbars have different thicknesses. When the clamping device clamps the copper busbars of different thicknesses, the clamping device is fixed and cannot be accurately aligned with the copper busbar holes. Therefore, the position of the clamping device needs to be adjusted. However, when the clamping device is fixed by bolts, the adjustment method is inconvenient. Therefore, a clamping fixture for capacitor assembly and welding is needed to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a clamping fixture for capacitor assembly and welding, which can achieve the effect of adaptive clamping of copper busbars of different thicknesses.

[0007] To achieve the above objectives, this application provides the following technical solution: a clamping fixture for capacitor assembly and welding, comprising a main platform, support platforms on both sides of the main platform, pressure plates on the support platforms, positioning pins between the pressure plates and the support platforms, side fixing platforms installed at the ends of the main platform, a pressing mechanism installed on the main platform, the pressing mechanism comprising a main rod, the main rod being an integral structure composed of a screw and a hexagonal head at the top of the screw, a sliding cavity being formed inside the screw, a movable groove communicating with the sliding cavity being formed on the hexagonal head, a sliding rod being slidably installed in the sliding cavity, a holding end being provided at the top of the sliding rod, a step being provided at the bottom of the sliding rod, and a spring being disposed between the step and the top of the sliding cavity.

[0008] Preferably, a pull head is fixed on the pressing end.

[0009] Preferably, a nut is threaded onto the screw, and the nut is used to limit the movement of the screw.

[0010] Preferably, the movable groove has a U-shaped structure design.

[0011] The beneficial effects of this application are as follows: The clamping fixture for capacitor assembly and welding provided by this application uses the elastic force of the spring applied to the step to make the slide rod always subject to a downward force. The slide rod moves up and down along the slide cavity under the external force. With the action of the spring force, the slide rod is suitable for resetting and is limited and pressed against the copper busbar under the action of the pressing end. The pressing end is suitable for moving in the movable groove of the hexagonal head, so as to achieve the purpose of pressing and limiting copper busbars of different thicknesses and achieve the effect of adaptive pressing of copper busbars of different thicknesses.

[0012] In addition to the purposes, features, and advantages described above, this application has other purposes, features, and advantages. A further detailed description of this application will be provided below with reference to the figures. Attached Figure Description

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0021] like Figures 1-2 As shown, this application provides a clamping fixture for capacitor assembly and welding, including a main table 1 and a support table 13 disposed on both sides of the main table 1. A pressure plate 11 for limiting and holding copper busbars is installed on the support table 13, and a positioning pin 14 is inserted between the support table 13 and the pressure plate 11 to limit the pressure plate 11 on the support table 13 and limit the copper busbars with the pressure plate 11.

[0022] A side platform 12 for supporting copper busbars is provided at the end of the main platform 1. The side platform 12 has through holes corresponding to the copper busbars and works with the positioning pin 14 to limit the copper busbars. A pressing mechanism 2 is provided on the side of the side platform 12 and is installed on the main platform 1.

[0023] like Figures 2-3 As shown, the pressing mechanism 2 includes a main rod 21, which is an integral structure consisting of a hexagonal head 211 and a screw 212 disposed below the hexagonal head 211. The screw 212 is adapted to cooperate and fix with the main platform 1, and a nut 25 is threadedly connected to the screw 212. The nut 25 is adapted to limit the screw 212.

[0024] Furthermore, a sliding cavity 214 is provided inside the screw 212, and a movable groove 213 is provided at the side end of the hexagonal head 211. The movable groove 213 is U-shaped and communicates with the sliding cavity 214. At the same time, a sliding rod 22 is slidably installed in the sliding cavity 214 of the main rod 21. The top end of the sliding rod 22 is provided with a pressing end 221 for pressing the copper busbar. The pressing end 221 is located in the movable groove 213 of the hexagonal head 211, and a pull head 23 is fixed on the pressing end 221. The pull head 23 is suitable for pulling the sliding rod 22 to move up and down along the sliding cavity 214.

[0025] Furthermore, a step 222 is provided at the bottom end of the slide rod 22, which is located inside the slide cavity 214, and a spring 24 is provided between the step 222 and the top surface of the slide cavity 214.

[0026] When assembling the copper busbar and capacitor core, first place the capacitor core in the main platform 1, then place the copper busbar on the capacitor core, and use the side platform 12 and support platform 13 to lift the edge of the copper busbar. At this time, pull the pull head 23 and drive the slide rod 22 to move upwards towards the hexagonal head 211, and indirectly drive the pressing end 221 to slide along the movable groove 213. At the same time, the step 222 squeezes the spring 24, causing the spring 24 to contract. When the pressing end 221 is above the copper busbar, release the pull head 23. Under the action of the spring 24, the spring 24 applies a downward elastic force to the step 222, thereby driving the slide rod 22 to move downwards, so that the pressing end 221 presses and limits the copper busbar, and achieves the purpose of limiting and pressing copper busbars of different thicknesses.

[0027] Meanwhile, the installation position of the pressing mechanism 2 is determined according to the actual capacitor assembly requirements, and no further restrictions are imposed here;

[0028] In summary, the elastic force applied to the step 222 by the spring 24 ensures that the slide rod 22 is always subjected to a downward force. The slide rod 22 moves up and down along the slide cavity 214 under the influence of external force. Combined with the elastic force of the spring 24, the slide rod 22 is suitable for resetting and, under the action of the holding end 221, limits and holds the copper busbar. The holding end 221 is suitable for moving within the movable groove 213 of the hexagonal head 211, thereby achieving the purpose of pressing and limiting copper busbars of different thicknesses and achieving the effect of adaptive pressing of copper busbars of different thicknesses.

[0029] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations are possible for those skilled in the art. Any improvements and modifications made within the spirit and principles of this application, without departing from its underlying principles, should also be considered within the scope of protection of this application.
