[0026] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0027] Please refer to Figure 1-6 , Figure 10 To achieve the above objectives, this utility model provides a milling device for the upper anode busbar 2 of an electrolytic cell, which, as a specific embodiment, includes: Frame 1 is a rectangular frame structure; The lifting frame 12 is installed on one side of the frame 1, moving up and down along the length of the frame 1; Milling unit 3 is mounted on frame 1; The mounting bracket 10 is located on the side of the frame 1 opposite to the lifting frame 12; The frame 1 has four positioning platforms 16 on the side near the mounting frame 10. The mounting frame 10 has a pressure plate 100. The end faces of the four positioning platforms 16 are in a virtual plane. The lifting direction of the lifting frame 12 is parallel to the virtual plane. The pressure plate 100 can move in a direction perpendicular to the virtual plane.

[0028] For details, please refer to Figure 1 - Figure 6 The frame 1 has a top plate 1a at the top and a bottom plate 1b at the bottom. The lower surface of the bottom plate 1b is used to install rollers 1c, and the upper surface of the top plate 1a is used to install the drive unit for lifting the lifting frame 12. The frame 1 adopts a rectangular frame structure and is vertically installed during use, which can adapt to the narrow working space above the electrolytic cell. With the above-mentioned configuration, when using it, refer to... Figure 1 The mounting bracket 10 can be lifted by a gantry crane and attached to the upper end of the busbar. The frame 1 can be moved so that the side of the busbar to be milled contacts the four positioning tables 16. Then, the pressure plate 100 applies pressure to the other side of the busbar, thereby forming a bidirectional limit and achieving a fixing effect. Then, the milling unit 3 is controlled to work and the milling depth is adjusted. Then, the lifting table is controlled to rise and fall to perform milling work on the busbar. With this device, the busbar can be milled online without removing the anode busbar 2, which effectively reduces downtime and labor intensity.

[0029] It should be noted that the milling unit 3 uses a milling device commonly used in this field.

[0030] Furthermore, as a preferred embodiment, along the width direction of the frame 1, two first clamping bolts 101 are spaced apart at the end of the mounting bracket 10 away from the frame 1, and a pressure plate 100 is disposed on the side of the first clamping bolts 101 near the frame 1, with the end of the first clamping bolt 101 abutting against the pressure plate 100. (Reference) Figure 1 - Figure 6 , Figure 8 , Figure 9 A vertical plate is provided at the end of the mounting bracket 10 away from the frame 1. Along the width of the frame 1, two first threaded holes 105 are spaced apart on the vertical plate. A first clamping bolt 101 is threaded into the first threaded holes 105. A pressure plate 100 is located on the side of the vertical plate closer to the frame 1, and the end of the first clamping bolt 101 abuts against the pressure plate 100. When the device needs to be fixed, rotating the first clamping bolt 101 moves it along its own axis, pushing the pressure plate 100 towards the positioning table 16 until the pressure plate 100 is tightly fitted with the relevant structure of the electrolytic cell, achieving rapid clamping and fixing of the equipment. When the equipment needs to be disassembled or its position adjusted, rotating the first clamping bolt 101 in the opposite direction resets the pressure plate 100 under external force or with the assistance of subsequent structures, making operation convenient.

[0031] Furthermore, as a preferred embodiment, refer to Figure 9 The pressure plate 100 is provided with positioning grooves 1001 corresponding to the two first clamping bolts 101. The ends of the first clamping bolts 101 can extend into the positioning grooves 1001 for limiting their position, ensuring the posture of the pressure plate 100, and ensuring that the thrust of the first clamping bolts 101 can be fully transmitted to the pressure plate 100, thereby improving the moving efficiency and fixing effect of the pressure plate 100. At the same time, the positioning grooves 1001 ensure that the first clamping bolts 101 and the pressure plate 100 always maintain a corresponding positional relationship, avoiding bolt misalignment caused by long-term use, ensuring consistency and stability of each fixing operation, and further improving the ease of use of the equipment.

[0032] Furthermore, as a preferred embodiment, a guide rod 103 is also provided on the hanging frame 10 between the two first clamping bolts 101. One end of the guide rod 103 is connected to the pressure plate 100, and the other end of the guide rod 103 away from the frame 1 is provided with a limiting surface. A compression spring 102 is sleeved on the guide rod 103, and the two ends of the compression spring 102 abut against the limiting surface and the connecting frame, respectively. Specifically, a guide hole 104 is provided on the vertical plate between the two first threaded holes 105. The guide hole 104 guides and fits the guide rod 103. The middle area of ​​the guide rod 103 and the pressure plate 100 is detachably threaded, and the other end is provided with a limiting plate, wherein the limiting surface is the plate surface of the limiting plate. Through the above arrangement, the guide rod 103 provides precise guidance for the movement of the pressure plate 100, ensuring that the pressure plate 100 always moves in a direction perpendicular to the virtual plane, avoiding the pressure plate 100 from shifting, which could lead to insecure fixing or damage to the equipment. When the first clamping bolt 101 is rotated to push the pressure plate 100 to move, the pressure plate 100 drives the guide rod 103 to move synchronously, and the limiting surface compresses the compression spring 102, which generates elastic potential energy. When the first clamping bolt 101 is loosened, the compression spring 102 releases its elastic potential energy, and pushes the guide rod 103 through the limiting surface to drive the pressure plate 100 to automatically reset. There is no need for manual pulling of the pressure plate 100, which simplifies the operation process and improves work efficiency.

[0033] Furthermore, as a preferred embodiment, refer to Figure 1 - Figure 6 Located below the mounting bracket 10, the frame 1 also has a lower positioning bracket 15, on which a second clamping bolt 152 is installed. Specifically, a lower positioning bracket 15 is installed below the mounting bracket 10, and a second clamping bolt 152 is installed on the lower positioning bracket 15. (Reference) Figure 1By setting the second clamping bolt 152, after the bracket 10 is hung on the busbar, the upper and lower parts of the busbar are clamped and positioned by the pressure plate 100 and the second clamping bolt 152 respectively, ensuring that the busbar can be accurately attached to the positioning table 16. The upper and lower two-point positioning can better position and match the frame 1 with the busbar. Through the double fixing structure, the equipment is subjected to more even force during operation, avoiding the tilting or shaking of the equipment caused by single-point fixing, and greatly improving the installation stability of the equipment.

[0034] Furthermore, as a preferred embodiment, a lifting rod 150 is provided at the end of the lower positioning frame 15 away from the frame 1 and parallel to the lifting direction of the lifting frame 12. The second clamping bolt 152 is provided at the upper end of the lifting rod 150. Specifically, by providing the lifting rod 150, when the mounting bracket 10 is hung on the busbar, the lifting rod 150 can be lowered to provide sufficient space for hanging on the busbar. After hanging, the lifting rod 150 can be raised to ensure that the second clamping bolt 152 can correspond to the busbar, ensuring the clamping effect and thus improving the convenience of use.

[0035] Furthermore, as a specific implementation method, refer to Figure 4 The lifting rod 150 is a threaded screw, and the upper end of the screw is rotatably fitted with a swing member 151 around its axis. The second clamping bolt 152 is connected to the swing member 151. Specifically, a rigid block 153 is welded to the end of the lower positioning frame 15. The rigid block 153 is provided with a second threaded hole 154. The lifting rod 150 is a screw threaded to the second threaded hole 154, and a ball head is provided at its upper end. The swing member 151 is connected to the lifting rod 150 through a ball joint. The lifting rod 150 is adjusted by rotating it.

[0036] Furthermore, as a specific implementation, the frame 1 is provided with two guide members 11 arranged in parallel and spaced apart and a first lead screw 14. Each guide member 11 is provided with a sliding member 13. The lifting frame 12 is connected to the sliding member 13. The lifting frame 12 is also provided with a lead screw nut that is threadedly connected to the lead screw. The top of the frame 1 is provided with a drive device 141 that is driven by the lead screw.

[0037] Specifically, the guide component 11 is a guide rail mounted on the frame 1, the sliding component 13 is a slider, the two ends of the lead screw are rotatably engaged with the top plate 1a and the bottom plate 1b, the drive device 141 is a worm gear screw reducer mounted above the top plate 1a, the output shaft of the reducer is driven by the lead screw, the lead screw nut (not shown in the figure) is connected to the lifting frame 12, the working chamber drive device 141 drives the lead screw to rotate, and through the threaded engagement of the first lead screw 14 and the lead screw nut, the rotational motion is converted into the linear lifting motion of the lifting frame 12. The cooperation of the two guide components 11 and the sliding component 13 provides dual guidance for the lifting of the lifting frame 12, ensuring that the lifting frame 12 does not deviate or shake during the movement, and improving the motion accuracy.

[0038] Furthermore, as a specific implementation method, refer to Figure 7 The specific structure of the milling unit 3 is as follows: the milling unit 3 includes a dovetail plate 34 mounted on the lifting frame 12, a milling cutter holder 33 that slides and guides the dovetail plate 34, a milling cutter shaft 310 rotatably mounted on the milling cutter holder 33, a milling cutter head 31 mounted at the end of the milling cutter shaft 310, and a motor 32 that is driven and connected to the milling cutter shaft 310.

[0039] Specifically, the milling unit 3 includes a dovetail plate 34 mounted on the lifting frame 12, a milling cutter holder 33 that slides and guides the dovetail plate 34, a milling cutter shaft 310 that is rotatably mounted on the milling cutter holder 33, a milling cutter head 31 mounted at the end of the milling cutter shaft 310, and a motor 32 that is driven and connected to the milling cutter shaft 310. The motor 32 drives the milling cutter shaft 310 to rotate, thereby driving the milling cutter head 31 to rotate to achieve milling work. The dovetail plate 34 slides and guides the milling cutter holder 33, allowing the milling cutter holder 33 to move along the length of the dovetail plate 34, adjusting the feed depth of the milling cutter head to adapt to different milling depth requirements. When connected to the busbar, the milling head can be retracted to avoid collision between the milling head and the busbar. As a specific implementation, the dovetail plate 34 and the milling cutter holder 33 can adopt the matching structure of the dovetail plate 34 and the slide table commonly used in the machine tool and lathe fields. The milling cutter holder 33 is the slide table. The dovetail plate 34 is provided with a groove (not shown in the figure) to accommodate the lead screw. A second lead screw 301 is rotatably arranged in the groove. The second lead screw 301 is provided with a second lead screw 301 nut (not shown in the figure). The milling cutter holder 33 is connected to the second lead screw 301 nut (not shown in the figure). The second lead screw 301 is connected to a handwheel 30. The position of the milling cutter holder 33 can be adjusted by rotating the second lead screw 301 through the handwheel 30.

[0040] Furthermore, as a preferred embodiment, the positioning platform 16 is threadedly connected to the frame 1. With this configuration, the length of the positioning platform 16 extending beyond the frame 1 can be adjusted by rotating it. When the positioning platform 16 is worn or damaged, it can be adjusted independently by rotating it, and it can also be disassembled and replaced individually, reducing maintenance costs and difficulty.

[0041] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
