Abstract
Description
Technical Field
[0001] This utility model relates to the field of milling grooves for aluminum cathode carbon blocks, and in particular to a milling groove device for aluminum cathode carbon blocks. Background Technology
[0002] Aluminum cathode carbon blocks are conductive materials used at the bottom of aluminum electrolytic cells. As the cathode, they operate in high-temperature and highly corrosive electrolyte environments, providing a conductive path for the aluminum electrolysis process while withstanding the scouring and erosion of molten aluminum and the electrolyte. During processing, aluminum cathode carbon blocks are typically clamped and milled using a milling machine.
[0003] A search revealed that the Chinese patent "A Milling Device for Aluminum Cathode Carbon Blocks" (authorization announcement number CN221021772U) features guide devices on both sides of the mounting base corresponding to the milling cutter head, enabling automatic centering of the milling cutter head. During operation, with the aluminum cathode carbon block groove facing upwards, the guide devices make contact with the two groove walls of the corresponding groove in the aluminum cathode carbon block. This ensures that the milling cutter head is positioned on the centerline of the corresponding groove in the aluminum cathode carbon block, guaranteeing consistent groove depth on both groove walls. This eliminates the need for clamping and positioning the aluminum cathode carbon block using lifting equipment and for tool setting, significantly improving operational efficiency.
[0004] Although the cathode carbon block itself is relatively heavy in the above application, a large milling force will be generated between the milling cutter and the cathode carbon block during the milling process. This milling force can easily cause the cathode carbon block to shift, thereby affecting the milling effect of the cathode carbon block.
[0005] Therefore, a milling device for aluminum cathode carbon blocks is proposed to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a milling device for aluminum cathode carbon blocks to solve the above-mentioned problems, thereby improving the problem that cathode carbon blocks are prone to displacement during milling.
[0007] This utility model achieves the above-mentioned objective through the following technical solution: a milling device for aluminum cathode carbon blocks, comprising: a milling machine; and an anti-deviation mechanism. The anti-deviation mechanism includes an electric push rod fixedly connected to both sides of the inner wall of the milling machine. A push plate is fixedly connected to the telescopic end of the electric push rod. Two air storage cylinders are fixedly connected to one side of the push plate. The air storage cylinders are filled with gas. A rubber plate is slidably connected to the inner wall of the air storage cylinder. An exhaust pipe is connected to one end of the air storage cylinder. A pressure sensor is fixedly connected to one end of the air storage cylinder. A first spring is fixedly connected to the opposite end of the air storage cylinder and the rubber plate. Through the electric push rod, air storage cylinder, first spring, exhaust pipe, and rubber plate, flexible pressure clamping of the aluminum cathode carbon block is achieved. The rubber plate and pressure sensor ensure timely closure of the electric push rod, thereby ensuring that the rubber plate presses against the side of the aluminum cathode carbon block, guaranteeing stable clamping of the aluminum cathode carbon block, avoiding over-clamping, and ensuring the milling effect of the aluminum cathode carbon block.
[0008] Preferably, a sealing gasket is slidably connected to the inner wall of the exhaust pipe, and a second spring is fixedly connected to one end of the sealing gasket. The elastic force of the second spring pushes the sealing gasket into the exhaust pipe, thereby ensuring the sealing gasket seals the inner wall of the exhaust pipe and preventing gas leakage from the inside of the gas storage tank.
[0009] Preferably, one end of the gas storage cylinder is connected to an air inlet pipe, and a one-way valve is embedded in the surface of the air inlet pipe. The one-way valve is used to prevent the gas inside the gas storage cylinder from being discharged through the air inlet pipe.
[0010] Preferably, filter frames are embedded at the ends of both the intake pipe and the exhaust pipe. These filter frames prevent debris generated during milling from entering the intake and exhaust pipes, thus ensuring the cleanliness of the air reservoir interior.
[0011] Preferably, a fixing block is fixedly connected to one side of the inner wall of the filter frame, the surface of the sealing gasket is slidably connected to the inner wall of the fixing block, and one end of the fixing block is fixed to one end of the second spring.
[0012] Preferably, a rubber ring is fixedly connected to the inner wall of the air storage cylinder, and the surface of the rubber plate is slidably connected to the inner wall of the rubber ring. The rubber ring ensures the sealing of the connection between the air storage cylinder and the rubber plate, preventing air leakage from occurring inside the air storage cylinder.
[0013] Preferably, a ball bearing is rotatably connected to the lower end of the surface of the push plate, and the surface of the ball bearing is rotatably connected to the top of the milling machine.
[0014] The beneficial effects of this utility model are:
[0015] 1. By using an electric push rod, an air tank, a first spring, an exhaust pipe, and a rubber plate, a flexible, constant-pressure clamping mechanism is achieved for the aluminum cathode carbon block. The rubber plate and a pressure sensor enable timely closing of the electric push rod, thereby ensuring that the rubber plate maintains constant pressure against the side of the aluminum cathode carbon block. Compared to existing cathode carbon blocks that are prone to displacement during milling, this method provides stable clamping of the cathode carbon block, avoiding over-clamping and ensuring the milling effect of the aluminum cathode carbon block.
[0016] 2. The elastic force of the second spring pushes the sealing gasket into the exhaust pipe, thereby ensuring the sealing gasket seals the inner wall of the exhaust pipe and preventing gas leakage inside the gas storage tank. Attached Figure Description

[0022] 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.
[0023] In practical implementation: such as Figure 1-4As shown, a milling device for aluminum cathode carbon blocks includes: a milling machine 1; and an anti-deviation mechanism 2. The anti-deviation mechanism 2 includes an electric push rod 21 fixedly connected to both sides of the inner wall of the milling machine 1. A push plate 22 is fixedly connected to the telescopic end of the electric push rod 21. Two air storage cylinders 24 are fixedly connected to one side of the push plate 22. The interior of the air storage cylinder 24 is filled with gas. A rubber plate 23 is slidably connected to the inner wall of the air storage cylinder 24. An exhaust pipe 25 is connected to one end of the air storage cylinder 24. A pressure sensor 26 is fixedly connected to one end of the air storage cylinder 24. A first spring 210 is fixedly connected to the opposite end of the air storage cylinder 24 and the rubber plate 23.
[0024] A lead screw is rotatably connected to the upper end of the inner wall of the milling machine 1. A first servo motor is fixedly connected to the upper end of the inner wall of the milling machine 1. The output shaft of the first servo motor is fixedly connected to one end of the lead screw. A slider is slidably connected to the upper end of the inner wall of the milling machine 1. The inner wall of the slider is threaded to the surface of the lead screw. A hydraulic cylinder is fixedly connected to the bottom of the slider. A protective shell is fixedly connected to the bottom end of the hydraulic cylinder. A second servo motor is fixedly connected to the inner wall of the protective shell. A milling cutter is rotatably connected to the lower end of the inner wall of the protective shell. The top end of the milling cutter is fixedly connected to the output shaft of the second servo motor. A CNC screen is fixedly connected to one side of the milling machine 1.
[0025] The CNC screen adopts an advanced CNC system to realize automated control of the milling process. Operators can set parameters such as the size, depth, and spacing of the milling groove through programming. The control system automatically controls the movement and feed speed of the milling power head, improving machining accuracy and production efficiency.
[0026] When the cathode carbon block needs to be milled, place the cathode carbon block at a suitable position at the end of the milling machine 1. By operating the CNC screen, the electric push rod 21 is automatically activated. The telescopic end of the electric push rod 21 moves, pushing the push plate 22 and the rubber plate 23 to move, so that the rubber plate 23 abuts against the side of the cathode carbon block. At this time, the telescopic end of the electric push rod 21 continues to push the push plate 22 to move. The movement of the push plate 22 drives the air storage cylinder 24 to move on the surface of the rubber plate 23, thereby causing the gas in the air storage cylinder 24 to be discharged through the exhaust pipe 25 and squeeze the first spring 210. The movement of the air storage cylinder 24 drives the pressure sensor 26 to move and abut against the pressure plate 210. When the pressure sensor 26 receives a compression signal from the rubber plate 23, it transmits the signal to the electric push rod 21, which then automatically closes the electric push rod 21. This causes the rubber plate 23 to press against the side of the aluminum cathode carbon with constant pressure. According to the process requirements, the operator inputs the relevant parameters for milling the groove into the CNC screen, such as groove width, groove depth, and groove spacing. The control system automatically starts the first servo motor, hydraulic cylinder, and second servo motor according to the set parameters, driving the milling cutter to move along the predetermined trajectory. The milling cutter rotates at high speed to mill the cathode carbon block, gradually removing excess material and forming the required groove shape.
[0027] like Figure 4As shown, a sealing gasket 27 is slidably connected to the inner wall of the exhaust pipe 25, and a second spring 29 is fixedly connected to one end of the sealing gasket 27. A fixing block 28 is fixedly connected to one side of the inner wall of one side of the filter frame 213. The surface of the sealing gasket 27 is slidably connected to the inner wall of the fixing block 28, and one end of the fixing block 28 is fixed to one end of the second spring 29. The sealing gasket 27 is a rubber component.
[0028] When the pressure of the gas discharged from the gas reservoir 24 is less than the elastic force of the second spring 29, the elastic force of the second spring 29 pushes the sealing gasket 27 to move to the inner wall of the exhaust pipe 25, thereby sealing the exhaust pipe 25.
[0029] like Figure 4 As shown, one end of the air storage cylinder 24 is connected to an air inlet pipe 211. A one-way valve 212 is embedded in the surface of the air inlet pipe 211. The one-way valve 212 is used to prevent the gas inside the air storage cylinder 24 from being discharged through the air inlet pipe 211. Filter frames 213 are embedded in the ends of both the air inlet pipe 211 and the exhaust pipe 25.
[0030] The telescopic end of the electric push rod 21 pulls the push plate 22 and the rubber plate 23 to move. At this time, the elastic force of the first spring 210 pushes the rubber plate 23 to move inside the air storage cylinder 24, so that suction is generated inside the air storage cylinder 24. The outside gas is filtered through the filter frame 213 and then enters the air storage cylinder 24 through the air inlet pipe 211 and the one-way valve 212.
[0031] like Figure 4 As shown, a rubber ring 214 is fixedly connected to the inner wall of the air storage cylinder 24, the surface of the rubber plate 23 is slidably connected to the inner wall of the rubber ring 214, and a ball bearing 215 is rolledly connected to the lower end of the surface of the push plate 22. The surface of the ball bearing 215 is rolledly connected to the top of the milling machine 1.
[0032] When in use, this utility model automatically activates the electric push rod 21. The telescopic end of the electric push rod 21 moves, pushing the push plate 22 and the rubber plate 23 to move, so that the rubber plate 23 abuts against the side of the cathode carbon block. At this time, the telescopic end of the electric push rod 21 continues to push the push plate 22 to move. The movement of the push plate 22 drives the gas storage cylinder 24 to move on the surface of the rubber plate 23, thereby causing the gas in the gas storage cylinder 24 to be discharged through the exhaust pipe 25 and squeeze the first spring 210. The movement of the gas storage cylinder 24 drives the pressure sensor 26 to move and abut against one end of the rubber plate 23. The pressure sensor 26 receives a squeeze signal and transmits it to the electric push rod 21, thereby causing the electric push rod 21 to automatically close, so that the rubber plate 23 presses against the side of the aluminum cathode carbon block.
[0033] It should be noted that the milling machine 1, electric push rod 21, air tank 24, pressure sensor 26, one-way valve 212, ball bearing 215, first servo motor, hydraulic cylinder, second servo motor, CNC screen and milling cutter mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the electric push rod 21, pressure sensor 26, first servo motor, hydraulic cylinder, CNC screen and second servo motor can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.
[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
