Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum busbar electro-erosion surface treatment, and particularly relates to a high-precision milling machine. Background Art

[0002] In the process of electrolytic aluminum production, aluminum busbars are used as conductors to transmit the current of electrolytic cells. Electrical energy is transmitted from the aluminum busbars to the anode rods through the contact surfaces. The anode rods and the aluminum busbars are crimped by clamps. Due to the consumption of the anodes, the anode rods need to be replaced and slid up and down regularly under the energized state. When the rods are replaced or slid, contact arcing occurs, forming an electro-erosion surface on the surface of the aluminum busbars, which affects the contact effect with the anode rods. To ensure that the contact area with the anode rods reaches more than 90%, during the major overhaul of the electrolytic cells, it is necessary to process the aluminum welding slag on the electro-erosion surface of the aluminum busbars to increase the surface smoothness of the busbars, and then increase the contact area between the busbars and the anode rods to solve the problem of decreased conductivity.

[0003] In the prior art, a milling machine is generally used to process the electro-erosion surface of aluminum busbars. However, in the prior art, when the milling machine for the electro-erosion surface of aluminum busbars processes the aluminum welding slag, its feed is not stable enough. After processing the electro-erosion surface of the aluminum busbars, it is difficult to make the surface of the aluminum busbars smooth enough, so the effect of increasing the contact area between the busbars and the anode rods is poor, and thus the effect of increasing its conductivity is poor. Moreover, the existing milling machine has no limit during feeding, which may also cause excessive grinding of the electro-erosion surface, being unfavorable for the contact and conductivity between the busbars and the anode rods. Therefore, it is necessary for the utility model to propose an improved design of the milling machine, aiming to provide a more stable and accurate treatment solution for the electro-erosion surface of aluminum busbars. Summary of the Utility Model

[0040] An embodiment of the present utility model provides a high-precision milling machine. As Figure 1-19 shown, the high-precision milling machine includes: a main frame 1 for mounting on an electrolytic cell device, and a milling mechanism 4 for milling aluminum welding slag on the electrically etched surface of the aluminum busbar of the electrolytic cell device; wherein, a lifting assembly 2 is installed on the main frame 1 for lifting the milling mechanism 4 to perform up-and-down feed on the etched surface; and a horizontal movement assembly 3 is assembled on the lifting assembly 2 for horizontally moving the milling mechanism 4 to perform feed on the etched surface.

[0041] In this embodiment, the lifting assembly 2 provided on the main frame 1 provides a stable and precise lifting motion to lift the milling mechanism 4, so that when the milling mechanism 4 works on the electrically etched surface of the aluminum busbar, it performs feed in the vertical direction. By means of the horizontal movement assembly 3 provided on the lifting assembly 2, the movement of the milling mechanism 4 in the Z direction is enabled, so that the milling mechanism 4 performs feed, improving the stability and precision of the feed, thereby machining the electrically etched surface of the aluminum busbar into a smooth and flat surface, which is beneficial for the contact and conduction between the busbar and the anode rod.

[0042] In a further preferred embodiment of the present utility model, the main frame 1 includes a bottom plate 11, a top plate 12, two columns 13 and a hook 14. The two columns 13 are fixedly installed at the top of the bottom plate 11 and the bottom of the top plate 12. The two columns 13 are symmetrically arranged, and both of the two columns 13 are in the shape of angle steel. The hook 14 is fixedly installed on the two columns 13 for hanging on the electrolytic cell device.

[0043] In this embodiment, the design of the main frame 1 not only ensures the stability and strength of the high-precision milling machine but also provides a convenient installation method. The main frame 1 includes a bottom plate 11, a top plate 12, two columns 13, and a hook 14. The bottom plate 11 serves as the foundation of the entire high-precision milling machine and provides stable support for other components. The top plate 12 is located at the top of the entire frame and works together with the bottom plate 11 to jointly bear various forces during the milling process. The two columns 13 are the key parts of the main frame 1. They are fixedly installed at the top of the bottom plate 11 and the bottom of the top plate 12, providing vertical support for the entire frame. The columns 13 are in the shape of angle steel, which not only has high strength but also can effectively resist vibration and impact force during the milling process. In addition, the two columns 13 are symmetrically arranged to ensure the stability and balance of the entire frame. The hook 14 is fixedly installed on the two columns 13 and is used to hang on the electrolytic cell equipment. This design enables the high-precision milling machine to be conveniently installed on the electrolytic cell equipment without complex installation steps and additional fixing devices. At the same time, the design of the hook 14 can also ensure that the high-precision milling machine remains stable during operation and avoid falling off or shifting due to vibration or impact force.

[0044] In a further preferred embodiment of the present utility model, the hook 14 includes two support hanging plates 141 and a limit plate 142. The two support hanging plates 141 are respectively fixedly installed on the two columns 13, and the limit plate 142 is fixedly installed on one side of the two support hanging plates 141, and the bottom of the limit plate 142 is lower than the bottom positions of the two support hanging plates 141.

[0045] In this embodiment, the design of the hook 14 is further optimized and refined. This design not only improves the stability and load-bearing capacity of the hook 14 but also ensures the safety and stability of the electrolytic cell equipment. Specifically, the hook 14 includes two support hanging plates 141 and a limit plate 142. The two support hanging plates 141 are respectively fixedly installed on the two columns 13. This structural design enables the hook 14 to be firmly fixed on the main frame 1 and is not easily detached or shaken. At the same time, the design of the support hanging plates 141 also enables the hook 14 to bear a large weight and force, ensuring the stability and safety of the electrolytic cell equipment during the milling process. The limit plate 142 is fixedly installed on one side of the two support hanging plates 141. This design can effectively limit the horizontal movement of the electrolytic cell equipment and prevent it from falling off or shifting due to vibration or impact force. In addition, the design that the bottom of the limit plate 142 is lower than the bottom positions of the two support hanging plates 141 can ensure that this equipment can be placed smoothly on the electrolytic cell equipment during hanging, and at the same time, the limit plate 142 can effectively prevent the main frame 1 from falling off the electrolytic cell equipment.

[0046] In a further preferred embodiment of the present utility model, a hanging plate 15 is welded to the top of the top plate 12. A lifting lug 16 is provided on the hanging plate 15, which is used for hoisting the equipment. The equipment can be lifted through the lifting lug 16, facilitating the installation of this equipment on the electrolytic cell equipment. A speed reducer fixing plate 17 is fixedly installed on the top of the top plate 12. The speed reducer fixing plate 17 is welded to the hanging plate 15, and the speed reducer fixing plate 17 is used for installing the driving equipment of the lifting assembly.

[0047] In this embodiment, the top plate 12 and its related components are designed and optimized in detail to improve the hoisting and installation convenience of the milling machine, while ensuring the stable operation of the lifting assembly. First, a hanging plate 15 is welded to the top of the top plate 12. This design enables the hoisting equipment to easily lift the entire milling machine through the lifting lug 16, improving the installation efficiency of the milling machine, being relatively labor-saving, and reducing the safety risks during the installation process. The main function of the speed reducer fixing plate 17 is to install the driving equipment of the lifting assembly, such as a speed reducer or other transmission devices. This design enables the driving equipment to be stably fixed on the milling machine, thus ensuring the smooth operation of the lifting assembly.

[0048] In a further preferred embodiment of the present utility model, the lifting assembly includes: two vertical slide rails 21 respectively and fixedly installed on the same side of the two columns 13 and arranged in parallel. Two lifting sliders 22 are slidably installed on the two vertical slide rails 21; a slide base 23 fixedly installed on the two lifting sliders 22. The slide base 23 is fixedly connected to the two lifting sliders 22. A mounting plate 24 is welded to one side of the slide base 23, which is used for installing the horizontal movement assembly; a cycloidal speed reducer 26 fixedly installed on one side of the speed reducer fixing plate 17, and the cycloidal speed reducer 26 is used to provide power for the lifting of the milling mechanism 4; an up-and-down feed screw 28 arranged between the bottom plate 11 and the top plate 12. The top end of the up-and-down feed screw 28 is installed with a coupling 27 connected to the output shaft of the cycloidal speed reducer 26; two square aligning bearing seats 29 are respectively and fixedly installed on the top of the bottom plate 11 and the bottom of the top plate 12. The up-and-down feed screw 28 is rotatably connected to the two square aligning bearing seats 29 through bearings; a copper sleeve 25 sleeved on the up-and-down feed screw 28. The copper sleeve 25 is threadedly connected to the up-and-down feed screw 28, and the copper sleeve 25 is fixedly connected to the mounting plate 24.

[0049] In this embodiment, the lifting assembly ensures that the milling mechanism 4 can move stably and precisely in the vertical direction to meet the requirements of the treatment of the electro-erosion surface of the aluminum busbar. First of all, the lifting assembly includes two vertical slide rails 21 respectively and fixedly installed on the same side of the two columns 13, and they are arranged in parallel. This design ensures the stability and parallelism of the slide rails, providing a basis for the smooth sliding of the lifting sliders 22. The lifting sliders 22 are slidably installed on the two vertical slide rails 21, and these sliders can move freely along the slide rails, realizing the lifting function of the milling mechanism 4. Secondly, one side of the slide base 23 installed on the lifting slider 22 is welded with a mounting plate 24 for installing the horizontal movement assembly 3. In this way, through the slide base 23 and the mounting plate 24, the horizontal movement assembly 3 and the lifting assembly 2 are organically combined together to jointly constitute the motion system of the milling machine.

[0050] In addition, a cycloidal reducer 26 is fixedly installed on one side of the reducer fixing plate 17, which provides power for the lifting of the milling mechanism 4. The output shaft of the cycloidal reducer 26 is connected to the top end of the up-and-down feed screw 28 through a coupling 27, thus realizing the transmission of power. The up-and-down feed screw 28 is arranged between the bottom plate 11 and the top plate 12, and its upper and lower ends are respectively rotatably installed with two square aligning bearing seats 29. This design enables the up-and-down feed screw 28 to rotate freely in the bearing seats, while ensuring the stability and accuracy of its rotation.

[0051] A copper sleeve 25 is sleeved on the up-and-down feed screw 28. It is threadedly connected with the up-and-down feed screw 28 and fixedly connected with the mounting plate 24. In this way, when the cycloidal reducer 26 drives the up-and-down feed screw 28 to rotate, the copper sleeve 25 will move up and down along the screw, thereby driving the mounting plate 24, the slide base 23 and the lifting slider 22 to slide on the vertical slide rail 21, realizing the lifting movement of the milling mechanism 4. The design of this lifting assembly not only ensures the stability and accuracy of the lifting movement of the milling mechanism, but also realizes the organic combination of power transmission and movement. It provides an efficient and reliable solution for the treatment of the electro-erosion surface of the aluminum busbar.

[0052] In a further preferred embodiment of the present utility model, two triangular reinforcing blocks 20 are welded between the slide base 23 and the mounting plate 24 for increasing the stability between the mounting plate 24 and the slide base 23.

[0053] In this embodiment, in order to improve the stability and connection strength between the slide base 23 and the mounting plate 24, two triangular reinforcing blocks 20 are especially welded between them. This design can improve the stability between the mounting plate 24 and the slide base 23, ensuring the smoothness and accuracy of the milling mechanism 4 during the lifting process.

[0054] In a further preferred embodiment of the present utility model, the horizontal movement assembly 3 includes: two laterally parallel slide rails 31 fixedly installed on the top of the mounting plate 24, on each of the two laterally parallel slide rails 31, a translation slider 32 is slidably installed; a motor fixing plate 33 fixedly installed on the two translation sliders 32 for installing the milling mechanism 4; a vertical self-aligning bearing block 341 and a diamond self-aligning bearing block 342 both fixedly installed on the top of the mounting plate 24; a feed screw 35 rotatably installed on the vertical self-aligning bearing block 341 and the diamond self-aligning bearing block 342, one end of the feed screw 35 is installed with a handwheel 36; a moving block 37 threadedly sleeved on the feed screw 35, and the moving block 37 is fixedly installed at the bottom of the motor fixing plate 33.

[0055] In this embodiment, the design of the horizontal movement assembly 3 is described in detail. This mechanism is responsible for realizing the precise movement of the milling mechanism 4 in the horizontal direction (Z-axis direction). First, the horizontal movement assembly 3 includes two laterally parallel slide rails 31, which are both fixedly installed on the top of the mounting plate 24. These two laterally parallel slide rails 31 provide a stable and smooth sliding path for the translation slider 32. The sliding of the translation slider 32 on the laterally parallel slide rails 31 enables the milling mechanism 4 to move freely in the horizontal direction. Next, a motor fixing plate 33 is fixedly installed on the two translation sliders 32 for installing the milling mechanism 4. The design of the motor fixing plate 33 enables the milling mechanism 4 to be stably fixed on the translation slider 32, thus ensuring the stability during the milling process. In addition, a vertical self-aligning bearing block 341 and a diamond self-aligning bearing block 342 are also fixedly installed on the top of the mounting plate 24. The design of these two bearing blocks is used to ensure the stability and precision of the feed screw 35 during rotation. One end of the feed screw 35 is installed with a handwheel 36, which is convenient for the operator to perform manual adjustment. On the feed screw 35, a moving block 37 is threadedly sleeved, and the moving block 37 forms a threaded connection with the feed screw 35. When the feed screw 35 rotates, the moving block 37 will move along the direction of the screw. This design enables the operator to precisely control the position of the moving block 37 by rotating the handwheel 36, thereby realizing the precise movement of the milling mechanism 4 in the horizontal direction. The bottom of the moving block 37 is fixedly installed on the motor fixing plate 33. In this way, when the moving block 37 moves, the motor fixing plate 33 and the milling mechanism 4 will also move accordingly. This design ingeniously realizes the movement function of the milling mechanism 4 in the horizontal direction, providing a flexible and precise operation method for the treatment of the electro-erosion surface of the aluminum busbar.

[0056] In a further preferred embodiment of the present utility model, a locking device is further installed at the bottom of the motor fixing plate 33. The locking device includes two locking screw rods 38 fixed to the motor fixing plate 33. The two locking screw rods 38 respectively penetrate through two strip-shaped holes formed in the mounting plate 24 and do not contact the inner walls of the strip-shaped holes. Threaded nuts 30 are installed on both of the two locking screw rods 38, and a runner 39 is welded to each of the two nuts 30. The runner 39 and the nut 30 are concentrically arranged. The runner 39 and the nut 30 are both located below the mounting plate 24. A retaining rod for blocking the nut 30 from falling off is welded to the bottom end of each of the two locking screw rods 38.

[0057] In this embodiment, a locking device is added to the bottom of the motor fixing plate 33. This design aims to improve the stability and safety of the milling mechanism during operation. Specifically, the locking device includes two locking screw rods 38, which respectively penetrate through two strip-shaped holes formed in the mounting plate 24. The design of these two strip-shaped holes allows the locking screw rods 38 to have a certain range of movement on the mounting plate 24, but the locking screw rods 38 do not contact the inner walls of the strip-shaped holes, which can avoid unnecessary friction and wear during the locking process.

[0058] Moreover, a nut 30 is threadedly installed on each locking screw rod 38, and the nut 30 can move freely on the locking screw rod 38. For the convenience of operation, a runner 39 is welded to the nut 30. The runner 39 and the nut 30 are concentrically arranged. By rotating the runner 39 to drive the nut 30 to rotate, it is more labor-saving. When it is necessary to lock the motor fixing plate 33, the operator only needs to rotate the nut 30 through the runner 39 to make the nut 30 move upward along the locking screw rod 38 until the bottom surface of the nut 30 is in close contact with the top surface of the mounting plate 24. In this way, the nut 30 can firmly fix the motor fixing plate 33 on the mounting plate 24 through friction, preventing it from loosening or displacing during operation, and effectively improving the stability and safety of the milling mechanism during operation, providing a more reliable guarantee for the treatment of the electro-erosion surface of the aluminum busbar.

[0059] In addition, a retaining rod for blocking the nut 30 from falling off is welded to the bottom end of each locking screw rod 38. This design is to prevent the nut 30 from falling off due to misoperation or other reasons during the locking process, thereby improving the reliability and safety of the entire locking device.

[0060] In a further preferred embodiment of the present utility model, the milling mechanism 4 includes: a three-phase asynchronous motor 41 fixedly installed on the motor fixing plate 33, an output shaft of the three-phase asynchronous motor 41 is connected with a sleeve 42, and the sleeve 42 is concentrically arranged with the output shaft of the three-phase asynchronous motor 41; a cutter head 44 fixedly installed at one end of the sleeve 42, the cutter head 44 is used for milling the aluminum welding slag on the electro-erosion surface of the aluminum busbar, a cutter head fixing plate 43 is fixedly sleeved on the sleeve 42, and the cutter head fixing plate 43 is fixedly connected with the cutter head 44, which is used to increase the balance and stability of the cutter head 44.

[0061] In this embodiment, the milling mechanism 4 is the core part for realizing the function of milling the aluminum welding slag on the electro-erosion surface of the aluminum busbar. The milling mechanism 4 includes a three-phase asynchronous motor 41 fixedly installed on the motor fixing plate 33. The three-phase asynchronous motor 41 serves as a power source, and its output shaft is connected with the sleeve 42. Through the sleeve 42, it is transmitted to the cutter head 44. The cutter head 44 is the main tool for milling the aluminum welding slag on the electro-erosion surface of the aluminum busbar, and is used to remove the aluminum welding slag on the electro-erosion surface of the aluminum busbar. In order to improve the balance and stability of the cutter head 44, a cutter head fixing plate 43 is fixedly sleeved on the sleeve 42. The cutter head fixing plate 43 is fixedly connected with the cutter head 44. The cutter head fixing plate 43 can also reduce the vibration of the cutter head 44 to a certain extent during the milling process and improve the milling quality.

[0062] It should be noted that in this solution, an electric control cabinet 6 (as Figure 12 shown) is also equipped. The electric control cabinet 6 is the control center of the entire device. When in use, each electrical equipment can be started separately through the electric control cabinet 6. The power connection method of each electrical equipment is an existing mature technology, which is well-known to those skilled in the art, has been widely verified and applied, and has high reliability and stability. Therefore, no redundant description will be made here to avoid unnecessary repetition and redundancy.

[0063] In order to further improve the use effect of the present device, in addition to the above solution, this solution also has the following embodiments:

[0064] In another embodiment of the present utility model, a protection component for protecting the debris generated during the operation of the cutter head 44 is further assembled on the sliding seat 23. The protection component is used to prevent the debris from splashing everywhere. The protection component includes: a fixing frame 71 fixedly installed on one side of the sliding seat 23; a first protective cover 72 fixedly installed on one side of the fixing frame 71, an outer sleeve 74 is installed on one side of the first protective cover 72, and the sleeve 42 passes through the outer sleeve 74; a second protective cover 73 slidably installed on the inner wall of the first protective cover 72, both sides of the second protective cover 73 are open, and a plurality of telescopic connection mechanisms are arranged on the second protective cover 73 and the first protective cover 72.

[0065] In this embodiment, a protective component is added to the original solution. This component is mainly used to protect against the debris generated during the operation of the cutter head 44, preventing the debris from splashing everywhere and improving the safety of the working environment. Specifically, the protective component includes a fixing frame 71 fixedly installed on one side of the slide base 23, a first protective cover 72 fixedly installed on one side of the fixing frame 71, and a second protective cover 73 slidably installed on the inner wall of the first protective cover 72. An outer sleeve 74 is installed on one side of the first protective cover 72, and the sleeve 42 passes through the outer sleeve 74. This design enables the first protective cover 72 to be close to the sleeve 42, reducing the splashing of debris from the gap between the sleeve 42 and the first protective cover 72. A number of telescopic connection mechanisms are provided between the second protective cover 73 and the first protective cover 72, allowing the first protective cover 72 and the second protective cover 73 to freely expand and contract as needed. When the cutter head 44 starts to operate, the second protective cover 73 will automatically extend forward under the action of the telescopic connection mechanism and closely fit on the electro-erosion surface of the aluminum busbar, preventing debris from splashing out from both sides. At the same time, the first protective cover 72 will also play its role, jointly forming a complete protective barrier with the second protective cover 73, ensuring the cleanliness and safety of the working environment, while also reducing the difficulty and frequency of cleaning work and improving work efficiency. This improvement makes the device more in line with the needs of users in practical applications and enhances its market competitiveness.

[0066] In another embodiment of the present utility model, the telescopic connection mechanism includes: a mounting block 83 fixedly installed on the outer wall of the second protective cover 73; a stop block 84 fixedly installed on the outer wall of the first protective cover 72; a sliding rod 85 slidably installed on the stop block 84, one end of the sliding rod 85 is fixedly connected to the mounting block 83, and a limit block is fixedly installed at the end of the sliding rod 85 away from the mounting block 83; a spring 86 slidably sleeved on the sliding rod 85, and the spring 86 is located between the mounting block 83 and the stop block 84.

[0067] In this embodiment, the telescopic connection mechanism is specifically described. The design of this mechanism aims to ensure the stable connection between the second protective cover 73 and the first protective cover 72 and allow the second protective cover 73 to freely expand and contract as needed. When the cutter head 44 approaches the electro-erosion surface of the aluminum busbar along with the slide base 23, the first protective cover 72 also moves accordingly, causing the stop block 84 to move and compress the spring 86, keeping the second protective cover 73 in contact with the surface of the electrolytic cell equipment. This not only realizes the stable connection and free expansion and contraction between the second protective cover 73 and the first protective cover 72, but also improves the overall stability of the protective component, and enables the second protective cover 73 to be flexibly adjusted according to different working requirements, further improving the use effect of the device.

[0068] In another embodiment of the present utility model, the protection mechanism is further equipped with a collection mechanism for collecting debris. The collection mechanism includes an installation box 76, a collection box 77 for containing debris is placed inside the installation box 76, a filter box 78 is fixedly installed on the top of the installation box 76, the filter box 78 is communicated with the installation box 76, a connecting pipe 81 is installed on the top of the filter box 78, the connecting pipe 81 is connected to a material discharge port provided at the bottom of the first protective cover 72, an air extractor 79 is fixedly installed on one side of the filter box 78, an air extraction pipe 80 is connected to the air inlet end of the air extractor 79, one end of the air extraction pipe 80 is communicated with the inside of the filter box 78, a filter screen plate 82 is fixedly installed inside the filter box 78, the filter screen plate 82 is right-angled and is hermetically connected to the inner walls of three sides and the top inner wall of the filter box 78.

[0069] In this embodiment, in order to improve the processing efficiency of debris and the cleanliness of the working environment, a collection mechanism for collecting debris is specially equipped. Specifically, the collection mechanism mainly includes components such as an installation box 76, a collection box 77, a filter box 78, a connecting pipe 81, an air extractor 79, an air extraction pipe 80, and a filter screen plate 82. The installation box 76 is used to place the collection box 77, and the collection box 77 is used to contain the debris generated from the cutter head 44. The filter box 78 is installed on the top of the installation box 76 and is communicated with the installation box 76. Such a design enables the debris to smoothly fall from the filter box 78 into the collection box 77. The connecting pipe 81 is installed on the top of the filter box 78 and is connected to a material discharge port provided at the bottom of the first protective cover 72. When the cutter head 44 works, the generated debris will fall from the material discharge port, pass through the connecting pipe 81, and fall into the filter box 78. The air extractor 79 is fixedly installed on one side of the filter box 78, and the air extraction pipe 80 is connected to the air inlet end of the air extractor 79 and is communicated with the inside of the filter box 78. Such a design enables the air extractor 79 to extract the air inside the filter box 78, forming a negative pressure environment, thereby accelerating the fall of the debris and also forming a negative pressure environment inside the first protective cover 72. External air can enter from the gap between the outer sleeve 74 and the sleeve 42, effectively preventing the debris from escaping from the gap between the outer sleeve 74 and the sleeve 42. A filter screen plate 82 is fixedly installed inside the filter box 78. The filter screen plate 82 is right-angled and is hermetically connected to the inner walls of three sides and the top inner wall of the filter box 78. The function of the filter screen plate 82 is to separate the debris from the air, only allowing the air to pass through, while the debris is intercepted on the filter screen plate 82 and gradually falls into the collection box 77 over time.

[0070] In summary, the collection mechanism in this embodiment effectively collects and filters the debris generated during the operation of the cutter head 44 through a clever design and the cooperation of components, maintaining the cleanliness of the working environment and improving the working efficiency. At the same time, the collection mechanism also has the advantages of simple structure, convenient operation, and easy maintenance, and has broad application prospects in practical applications.

[0071] In another embodiment of the present utility model, the first protective cover 72 is composed of an upper cover 721 and a lower cover 722, and the outer sleeve 74 is composed of two identical semi-cylindrical tubes. Two connecting blocks 75 are provided on both the upper cover 721 and the lower cover 722. The upper cover 721 is integrally formed with the upper semi-cylindrical tube and the two upper connecting blocks 75. The lower cover 722 is integrally formed with the lower semi-cylindrical tube and the two lower connecting blocks 75. And the connecting block 75 on the upper cover 721 is connected to the connecting block 75 on the lower cover 722 by bolts.

[0072] In this embodiment, the structure of the first protective cover 72 is further optimized to improve the convenience of its assembly and the reliability of its use. Specifically, the first protective cover 72 is designed to be composed of two parts, an upper cover 721 and a lower cover 722. The outer sleeve 74 is also correspondingly improved and is composed of two identical semi-cylindrical tubes. To ensure the firm and reliable connection between the upper cover 721 and the lower cover 722, the present utility model provides two connecting blocks 75 on both the upper cover 721 and the lower cover 722. The upper cover 721 is integrally formed with the upper semi-cylindrical tube and the two upper connecting blocks 75, and the lower cover 722 is integrally formed with the lower semi-cylindrical tube and the two lower connecting blocks 75. The advantage of this design is that the connection between the connecting block 75 and the upper cover 721 and the lower cover 722 is more firm and not easy to loosen. At the same time, by connecting the connecting block 75 on the upper cover 721 to the connecting block 75 on the lower cover 722 with bolts, the overall stability of the first protective cover 72 is further enhanced. And such a design makes it more convenient for assembly and disassembly, and is also beneficial for subsequent maintenance and replacement.

[0073] In summary, compared with the related technology, by setting the lifting component and the horizontal movement component and using a linear slide rail to replace the traditional dovetail rack, the milling mechanism 4 can move smoothly. The horizontal movement of the milling mechanism 4 in the Z direction shortens the length of the sleeve 42, increases the balance and stability of the cutter head 44, and the horizontal movement component 3 also enables the milling mechanism;

[0074] Moreover, the original locking method of the milling machine is changed from horizontal locking to vertical locking, which can not affect the stability of the cutter head 44 during the locking process and is more convenient and fast for locking;

[0075] Not only that, by adding a cutter head fixing plate 43, the high-precision milling machine increases the strength and connection method of the cutter head 44, makes the force on the cutter head 44 more uniform during rotation, and the rotation is more stable. Thus, when the cutter head 44 mills the aluminum welding slag on the electrochemically corroded surface of the aluminum busbar, it can mill the aluminum welding slag as flat as the outer wall of the electrolytic cell equipment, which is convenient for the connection of the conductive bar and has better conductivity;

[0076] In addition, a protection mechanism is added to the device to prevent the debris generated during the operation of the cutter head 44 from spilling out, and a collection mechanism is also equipped to efficiently collect and filter the debris, thereby maintaining the cleanliness of the working environment.
