Description

Technical Field

[0001] This utility model relates to the field of grinding devices, specifically a grinding device for the surface of a graphite electrode with a quick-release structure. Background Technology

[0002] Graphite electrodes are high-temperature resistant graphite conductive materials made from petroleum coke and pitch coke as aggregates and coal tar pitch as binders through processes such as raw material calcination, crushing and grinding, batching, kneading, molding, baking, impregnation, graphitization, and machining. To ensure the smoothness of the graphite electrode surface, it is necessary to optimize the surface of the graphite electrode after its production. Usually, a grinding machine is used to grind the graphite electrode.

[0003] Because graphite electrodes are relatively heavy, such as a graphite electrode with a diameter of 200mm and a length of 2000mm, which generally weighs more than 100kg, it is inconvenient for the grinding machine to clamp the graphite electrode. Usually, it is necessary to use lifting equipment to lift and clamp it, which is time-consuming and labor-intensive, and reduces the overall grinding efficiency. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 4 As shown, a graphite electrode surface polishing device with a quick-release structure includes a base 1, a fixed seat 2 fixedly connected to the top of the base 1, a polishing assembly mounted on the top of the fixed seat 2, the polishing assembly including a top plate 11, support rods 12 fixedly connected to the four corners of the top plate 11, insertion holes adapted to the support rods 12 opened at the four corners of the fixed seat 2, cylinders 13 for driving the top plate 11 to rise and fall are installed at both ends of the fixed seat 2, a linear module 14 is installed at the bottom of the top plate 11, a vertical rod 15 is installed at the output end of the linear module 14, a mounting seat 16 is installed at the bottom of the vertical rod 15, a polishing disc 17 is installed at the bottom of the mounting seat 16, a vertical plate 18 is fixedly connected to the bottom of the top plate 11 on one side of the linear module 14, a slide rail 19 is fixedly connected to the side of the vertical plate 18, a slider 20 is slidably connected to the slide rail 19, and a sleeve 21 sleeved on the outside of the vertical rod 15 is fixedly connected to the side of the slider 20 through a connecting rod.

[0020] The top plate 11 moves up and down by extending and retracting the cylinder 13, thereby adjusting the height of the grinding disc 17. The linear module 14 drives the vertical rod 15 to move, thereby adjusting the position of the grinding disc 17. The sleeve 21, slide rail 19 and slider 20 can prevent the friction generated during grinding from damaging the linear module 14.

[0021] The fixed base 2 has a grinding chamber in the middle of the top and a through groove at the bottom. Equipment chambers are located on both sides of the grinding chamber. Clamping plate 3 and clamping plate 4 are located at both ends of the grinding chamber. A central shaft 5 extending into the equipment chamber is fixed to the side of clamping plate 3. A motor 6 for driving the central shaft 5 to rotate is installed inside the equipment chamber. A positioning seat is fixed to the inner side wall of the equipment chamber. The central shaft 5 passes through and is rotatably connected to the positioning seat. The motor 6 is installed inside the equipment chamber through a horizontal plate, and the output shaft of the motor 6 is connected to the central shaft 5 through a coupling. A drive assembly for driving clamping plate 4 to move is located on one side of clamping plate 4.

[0022] The drive assembly includes a circular plate 22, with an annular rail 23 fixedly connected to one side of the circular plate 22. Multiple sliders 24 that are slidably connected to the annular rail 23 are fixedly connected to the side of the clamping plate 24. A cylinder 3 25 is installed inside an equipment compartment near the clamping plate 24. The output end of the cylinder 3 25 is connected to the circular plate 22. Multiple limiting rods 26 extending into the equipment compartment are fixedly connected to the side of the circular plate 22. A limiting cylinder 27 sleeved on the outside of the limiting rods 26 is installed through the side wall of the equipment compartment.

[0023] The motor 6 can drive the clamping plate 3 to rotate via the central shaft 5; the extension and retraction of the cylinder 25 causes the circular plate 22 to move the clamping plate 4, which can adjust the distance between the two clamping plates. The setting of multiple limit rods 26 and limit cylinders 27 can prevent the cylinder 25 from being subjected to forces from other directions.

[0024] Two guide rails 7 are installed on the top of the base 1. A base plate 8 is slidably connected to the top of the guide rails 7. Two sets of cylinders 9 are installed on the top of the base plate 8. A support seat 10 is installed at the output end of the cylinders 9. Slider blocks 28 that are slidably connected to the guide rails 7 are fixed at the four corners of the base plate 8. Handles 29 are installed at both ends of the base plate 8. Indicator blocks are fixed to the top of both sides of the base 1.

[0025] Two sets of cylinders 29 are installed on the top of the base plate 8. The graphite electrode to be ground can be placed on the support seat 10 on the top of the set of cylinders 29 away from the handle 29. By pushing the base plate 8 with the handle 29, when one side of the handle 29 is aligned with the indicator block on the side, the support seat 10 for placing the graphite electrode moves to the center directly below the grinding chamber. The cylinder 29 extends, causing the support seat 10 to lift the graphite electrode between the two clamping plates, which can clamp and fix the graphite electrode. After one graphite electrode is ground, a new graphite electrode to be ground is placed near the base plate 8. When the empty support seat 10 on the set of support seats 10 of handle 29 moves to the center directly below the grinding chamber, cylinder 29 extends to pick up the ground graphite electrode. Then cylinder 29 retracts to return to its original position and pushes the base plate 8 to move again, so that the other end of the base plate 8 is flush with another indicator block. At this time, the graphite electrode to be ground moves to the center directly below the grinding chamber. Following the same operation, the graphite electrode can be clamped and ground by the clamping plate. Then push the base plate 8 again to move the ground graphite electrode to the other side, where the unloading operation can be performed.

[0026] In practical use, this device is controlled by an external PLC controller. The graphite electrode to be ground is placed on a set of support seats 10. The base plate 8 is pushed to move so that the graphite electrode moves to the center of the grinding chamber. The cylinder 29 extends so that the support seat 10 lifts the graphite electrode between the clamping plate 3 and the clamping plate 4. The cylinder 325 extends so that the clamping plate 4 moves to clamp and fix the graphite electrode. The motor 6 drives the clamping plate 3 to rotate, which can realize the rotation of the graphite electrode. This is then used in conjunction with the grinding components to complete the grinding. The extension of the cylinder 29 moves the support seat 10 upward so that the ground graphite electrode can be picked up, realizing the disassembly and quick clamping of the graphite electrode and improving the grinding efficiency.
