[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 - Figure 3This utility model provides an embodiment of a copper busbar milling clamping fixture, including a support base 1, which serves as the basic component of the entire fixture, supporting and fixing all other components. A positioning mechanism is provided on the inner wall of the support base 1. The positioning mechanism includes a positioning component and a limiting component. The positioning component includes a movable frame 21, connected to a movable rod 25 via a hinge rod 24. When the movable rod 25 slides, it can slide smoothly on the inner wall of the support base 1 under the drive of the hinge rod 24, adapting to the clamping requirements of copper busbars of different sizes and achieving initial positioning of the copper busbar. The movable frame 21 is slidably connected to the inner wall of the support base 1. A groove is provided on the upper part of the support base 1 to provide a track for the sliding of the fixed column 22, ensuring that the movable frame 21 can move smoothly. The movable frame 21 is fixedly connected to a fixed column 22 on its upper part to position and clamp the copper busbar. The fixed column 22 slides on the inner wall of the slide groove. A baffle 23 is fixedly connected to the outer side of the fixed column 22 and slides on the inner wall of the slide groove. The baffle 23 closes the upper part of the slide groove, which can reduce the entry of debris into the support base 1 during copper busbar processing. A movable rod 25 is slidably connected to the inner wall of the support base 1. The movable frame 21 is driven to move through a hinge rod 24. The movable frame 21 and the movable rod 25 are hinged through the hinge rod 24. The hinge rod 24 connects the movable frame 21 and the movable rod 25 and plays a transmission role. When the movable rod 25 slides, the linear motion of the movable rod 25 is converted into the sliding of the movable frame 21 through the hinge rod 24.

[0032] Reference Figure 3 and Figure 4 The limiting component includes a pull rod 31. By pulling the pull rod 31, the limiting block 34 can slide within the guide groove 33, thereby enabling the limiting block 34 to be inserted into or separated from the slot 35. The pull rod 31 is slidably connected to the inner wall of the moving rod 25. A guide groove 33 is provided on the left side of the pull rod 31. The guide groove 33 is inclined and cooperates with the limiting block 34 to control the up and down movement of the limiting block 34. The limiting block 34 is slidably connected to the inner wall of the moving rod 25. The limiting block 34 moves in the guide groove 33 along the inclined direction, thereby enabling the limiting block 34 to be inserted into or separated from the slot 35. The limiting block 34 slides on the inner wall of the guide groove 33. A slot 35 is provided on the inner wall of the support base 1 near the upper part of the moving rod 25. Multiple slots are provided for insertion and cooperation with the limiting block 34, providing a fixed position for the limiting block 34 and realizing the limiting function of the moving rod 25 and the positioning component.

[0033] Furthermore, the limiting block 34 is inserted into the inner wall of the slot 35. The right side of the pull rod 31 is elastically connected to the moving rod 25 through a return spring 32. One end of the return spring 32 is fixedly connected to the outside of the pull rod 31, and the other end is fixedly connected to the inner wall of the moving rod 25. After the pull rod 31 is pulled, it provides elastic force to reset the pull rod 31, thereby driving the limiting block 34 back to its initial position, ensuring that the limiting component can be reused. The moving frame 21 is provided with two sets of moving rods 25, which are symmetrically arranged about the center line of the support base 1. The outer side of the fixed column 22 is made of rubber, which increases the friction with the copper busbar and can effectively prevent the copper busbar from sliding during processing, ensuring the positional accuracy of the milling groove. The right side of the pull rod 31 is T-shaped for easy operation by the operator.

[0034] Reference Figure 2 and Figure 5 An auxiliary component is provided on the inner wall of the support base 1. The auxiliary component includes a limiting member 41, which slides on the inner walls of the left and right sides of the support base 1. Driven by the rack 42, it assists in positioning and clamping the copper busbar, further improving the stability of the copper busbar during the milling process. The rack 42 is fixedly connected to the outer side of the limiting member 41 and meshes with the gear 43. When the gear 43 rotates, it drives the rack 42 to move, thereby driving the limiting member 41 to slide, realizing the auxiliary positioning and clamping action of the copper busbar. The rack 42 slides on the inner wall of the support base 1.

[0035] Furthermore, a gear 43 is rotatably connected to the inner wall of the support base 1 as a transmission component, transmitting the power of the geared motor 44 to the rack 42, causing the rack 42 to drive the limiting member 41 to move, thereby realizing the automated operation of the auxiliary components. The rack 42 meshes with the outer side of the gear 43. The geared motor 44 is fixedly connected to the bottom end of the support base 1 to provide power. By driving the gear 43 to rotate, the limiting member 41 is automatically slidable, reducing manual intervention and improving production efficiency. The output shaft of the geared motor 44 is fixedly connected to the lower part of the gear 43. A baffle 45 is fixedly connected to the outer side of the limiting member 41 to prevent debris from entering the interior of the support base 1. The baffle 45 slides on the upper part of the support base 1. Two sets of limiting members 41 and racks 42 are provided. The two sets of racks 42 and the center line of the support base 1 are asymmetrically arranged with symmetrical axes.

[0036] Working principle: When in use, after placing the copper busbar on the support base 1, pull the lever 31. The lever 31 slides on the inner wall of the moving rod 25. The sliding of the lever 31 will cause the limiting block 34 to slide along the inner side of the guide groove 33 and slide out from the inner wall of the slot 35, thus releasing the limitation on the moving rod 25.

[0037] At this point, the moving rod 25 is pushed to slide on the inner wall of the support base 1. The sliding of the moving rod 25 will drive the hinge rod 24 to move, thereby making the moving frame 21 slide smoothly on the inner wall of the support base 1. The fixed column 22 on the upper part of the moving frame 21 slides in the groove on the upper part of the support base 1. By adjusting the position of the moving rod 25, the two sets of fixed columns 22 are gradually brought closer to the copper busbar until the copper busbar is initially positioned and clamped. Because the outer side of the fixed column 22 is made of rubber, the friction between it and the copper busbar is large, which can effectively prevent the copper busbar from sliding during the processing and ensure the accuracy of the milling groove position.

[0038] At this point, the pull rod 31 is released, and under the elastic force of the return spring 32, the limit block 34 is inserted into the inner wall of the corresponding slot 35, thereby locking the position of the moving rod 25 and fixing the entire positioning assembly to prevent displacement of the positioning assembly during the milling process and ensure the stability of the copper busbar clamping.

[0039] Start the geared motor 44. The output shaft of the geared motor 44 drives the gear 43 to rotate. The rack 42, which meshes with the gear 43, slides on the inner wall of the support base 1, causing the two sets of limiting members 41 to slide on the inner walls of the left and right sides of the support base 1 to clamp the copper busbar and further improve the stability of the copper busbar during the milling process.

[0040] During the sliding process of the limiting component 41, the baffle 45 fixedly connected to its outer side slides on the upper part of the support base 1, which can prevent the debris generated during the copper busbar processing from entering the interior of the support base 1, thus avoiding the debris from affecting the normal operation of the tooling components.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
