[0002] The medium frequency furnace is a device that uses electricity to convert electrical energy into thermal energy. Its working principle is to generate high-frequency current through electrodes, transmit electrical energy to the working medium, and thus heat the working medium. Graphite electrode is one of the key components of the medium frequency furnace. It is usually necessary to drill holes at one or both ends of the electrode to connect the electrode to the power system.

[0003] The graphite electrode body is cylindrical, and both ends of the cylindrical body are fixed with truncated cone-shaped connecting sections, and the outer wall of the connecting section is equidistantly provided with multiple annular grooves (see Fig. 9 ), before drilling the graphite electrode, it is necessary to determine the position of the electrode screw hole to be processed on the connecting section, and then use mechanical equipment (such as a hydraulic press to drive an external pressure plate) to press and fix the graphite electrode, and ensure that during drilling, the drill bit axis is perpendicular to the outer wall of the graphite electrode connecting section, and then perform subsequent drilling processing on the graphite electrode.

[0004] The existing graphite electrodes have the following defects and problems during processing: 1. Since the graphite electrode is made of graphite with lower hardness, the graphite electrode is prone to uneven force when the electrode is fixed and clamped, which causes deformation or cracks in the graphite electrode. Secondly, the graphite electrode will move during processing due to the lack of clamping at the left and right ends, affecting the processing accuracy and efficiency; 2. The graphite electrode needs to be debugged and corrected for many times before processing to ensure that the axis of the screw hole to be processed is perpendicular to the outer wall of the graphite electrode connecting section, which increases the time and cost required for production and reduces work efficiency; 3. When drilling, the graphite electrode needs to meet different processing requirements, that is, when drilling different angles of the same connecting section, the staff needs to rotate the graphite electrode and reposition it, which will cause positioning errors due to movement, thereby reducing the drilling accuracy and product quality.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0033] like Figure 1 and Figure 2As shown, a medium frequency furnace electrode assembly drilling processing equipment includes a base 1, the base 1 for placing a graphite electrode 6 and a connecting section 61 is L-shaped and the interior of the vertical section is a cavity, a driving mechanism 4 is arranged on the rear side of the vertical section of the base 1, an arc-shaped placement groove is opened on the horizontal section of the base 1, and a side seat 2 with a cavity inside is arranged on the rear side of the base 1.

[0034] like Figure 2 and Figure 3 As shown, the driving mechanism 4 includes a worm 41, and the inner cavity of the side seat 2 is rotatably provided with a worm 41 whose axis extends from the back to the front, and the worm 41 is connected to an external motor (not shown in the figure), and the inner cavity of the vertical section of the base 1 is rotatably provided with a turbine 42 meshing with the worm 41, and a rotating disk 31 is provided on the left side of the turbine 42, and a clamping mechanism 3 is provided on the left side of the rotating disk 31, and a fixed disk 32 with a hollow interior is fixedly provided in the inner cavity of the base 1, and a rotating unit 37 is provided on the left side of the fixed disk 32. The driving mechanism 4 also includes a fitting unit 43, and a fitting unit 43 is provided on the front side of the side seat 2.

[0035] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the clamping mechanism 3 includes a sliding plate 342, and a plurality of sliding plates 342 are radially slidably arranged on the rotating disk 31. A fixing unit 35 is arranged on the left side of the sliding plate 342. The fixing unit 35 includes a transverse plate 351 for clamping the graphite electrode 6. An adjusting unit 36 ​​is arranged on the left side of each transverse plate 351. The upper adjusting unit 36 ​​includes an inclined plate 364 for placing the drilling mechanism 5. A pushing unit 44 for pushing the inclined plate 364 to slide left and right is arranged on the front side of the base 1.

[0036] During operation, the operator places the graphite electrode 6 in the placement groove on the horizontal section of the base 1, and then the external motor starts to drive the worm 41 to rotate. Through the meshing between the worm 41 and the turbine 42, the turbine 42 drives the rotating disk 31 to rotate synchronously. Secondly, a thread groove is provided on the left end face of the rotating disk 31, and a plurality of radially equidistantly distributed matching strips matching the thread groove are provided on the right end face of the sliding plate 342. When the rotating disk 31 rotates, the matching between the thread groove and the matching strip drives the plurality of sliding plates 342 to slide radially at the same time, and the plurality of sliding plates 342 are connected to the rotating disk 31. The movable plates 342 drive the fixed units 35 to evenly clamp the circumferential outer wall of the graphite electrode 6, and the adjustment units 36 on the left side of the transverse plate 351 cooperate with the fitting units 43, so that the multiple inclined plates 364 are all fitted with the inclined surface of the connecting section 61 on the left side of the graphite electrode 6, so that the adjustment units 36 fixed to the transverse plate 351 and the drilling mechanism 5 can remain perpendicular to the connecting section 61, ensuring that the axial position of the electrode screw hole to be processed on the left connecting section 61 can be perpendicular to the outer wall of the connecting section 61, avoiding deviation in the processed hole position, which affects the quality and service life of the graphite electrode 6.

[0037] Then the operator pushes the adjustment unit 36 ​​through the pushing unit 44, so that the adjustment unit 36 ​​and the base 1 clamp the left and right ends of the graphite electrode 6, and cooperates with the fixing unit 35, so that the graphite electrode 6 can be clamped synchronously and evenly, ensuring the stability and positioning accuracy of the graphite electrode 6 during the processing.

[0038] When different processing requirements need to be met, that is, drilling processing is performed on different angles of the same connecting segment 61, the positions of the clamping mechanism 3 and the drilling mechanism 5 are adjusted by rotating the rotating unit 37 without moving the graphite electrode 6 and the overall equipment, so as to achieve drilling processing at different positions of the same connecting segment 61, thereby reducing the positioning error caused by movement and ensuring the processing accuracy.

[0039] like Figure 3 , Figure 4 and Figure 5 As shown, the clamping mechanism 3 also includes a connecting plate 341, and a circular disc is rotatably provided in the inner cavity of the base 1, and a plurality of connecting plates 341 uniformly distributed in the circumferential direction are fixedly provided on the circumferential surface of the circular disc. The upper sliding plate 342 is taken as an example for explanation, and the upper sliding plate 342 is slidably sleeved on the corresponding connecting plate 341 up and down, and a horizontal plate 351 is fixedly provided on the left side of the sliding plate 342, and the horizontal plate 351 slides up and down and penetrates two limit plates 352 distributed on the left and right, and a clamping plate 353 is fixedly provided on the lower end surfaces of the two limit plates 352, and the end of the clamping plate 353 away from the horizontal plate 351 is arc-shaped, and a plurality of fixing springs 354 equidistantly arranged from left to right are jointly provided between the horizontal plate 351 and the clamping plate 353, and a positioning plate 355 of the internal cavity is fixedly provided on the upper end surface of the left side of the horizontal plate 351.

[0040] During operation, when the rotating disk 31 is driven to rotate by the working external motor, multiple sliding plates 342 slide radially toward the center point of the rotating disk 31 synchronously, and each sliding plate 342 slides on the corresponding connecting plate 341, so that each sliding plate 342 moves synchronously with the corresponding cross plate 351 toward the central axis of the graphite electrode 6, and the cross plate 351 drives the clamping plate 353, the limit plate 352 and the fixed spring 354 to move synchronously until the arc-shaped end face of the clamping plate 353 fits with the circumferential outer wall of the graphite electrode 6, and then the cross plate 351 moves synchronously and gradually compresses the fixed spring 354. The elastic force generated by the compression of the fixed spring 354 enables multiple clamping plates 353 to clamp the circumferential outer wall of the graphite electrode 6 synchronously and evenly, thereby ensuring the quality of the graphite electrode 6 produced by drilling and improving the stability during processing.

[0041] like Figure 6 and Figure 7 As shown, the pushing unit 44 includes a bonding plate 441, and a bonding plate 441 is provided on the front side of the side seat 2 for sliding left and right. The bonding plate 441 is driven by an external cylinder (not shown in the figure) to slide left and right. A ring plate 442 is slidingly provided between every two adjustment plates 362, and the distance between the front end face of the bonding plate 44 and the side seat 2 is greater than the distance between the rear end of the rear ring plate 442 and the side seat 2.

[0042] like Figure 5 , Figure 7 and Figure 8 As shown, the adjustment unit 36 ​​also includes a sliding rod 361, and the inner cavity of each positioning plate 355 is slidably provided with a sliding rod 361 whose axis extends from left to right, and each sliding rod 361 is fixedly sleeved with an adjustment plate 362. Taking the upper adjustment plate 362 as an example, a movable groove is provided at the bottom of the upper adjustment plate 362, and a plurality of connecting holes 367 are equidistantly provided on the left side of the adjustment plate 362 from top to bottom, and a movable plate 363 is slidably provided on the inner wall of the movable groove, and a plurality of fixing holes corresponding to the connecting holes 367 are equidistantly provided on the movable plate 363 from top to bottom, and fixing pins are commonly inserted in the connecting holes 367 and the corresponding fixing holes.

[0043] like Figure 7 and Figure 8 As shown, the bottom of the movable plate 363 is hinged with an inclined plate 364, and a hinge spring 365 is commonly provided between the inclined plate 364 and the movable plate 363. Taking the upper inclined plate 364 as an example for explanation, a plurality of clips 366 are fixedly provided on the lower end surface of the upper inclined plate 364 at equal intervals from left to right. The clips 366 are in the shape of a triangle with a larger top and a smaller bottom, and are made of high temperature resistant rubber material.

[0044] During operation, the operator drives the laminating plate 441 to move to the right through the external cylinder, and the laminating plate 441 contacts the ring plate 442 and drives the ring plate 442 to move synchronously, so that each ring plate 442 drives the corresponding adjustment plate 362 to move synchronously, and the adjustment plate 362 drives the sliding rod 361 to slide in the inner cavity of the positioning plate 355 until multiple adjustment plates 362 contact the left side of the graphite electrode 6 body. The left and right ends of the graphite electrode 6 are clamped and fixed by cooperating with the base 1 through the adjustment plate 362, which further improves the stability of the clamping mechanism 3, reduces the error caused by drilling processing, ensures that the graphite electrode 6 maintains a constant position and angle during processing, and improves the processing accuracy.

[0045] The operator fixes the movable plate 363 to the inner wall of the movable groove of the adjustment plate 362 by fixing the pin, and adjusts the distance between the movable plate 363 and the inner wall of the movable groove according to the distance between the outer wall of the main body of the graphite electrode 6 and the circumferential outer wall of the left connecting section 61, so as to ensure that the bottom of the movable plate 363 can contact the circumferential outer wall of the left connecting section 61 while the clamping plate 353 clamps the main body of the graphite electrode 6, so that the equipment can process graphite electrodes 6 of different sizes, thereby enhancing the flexibility and practicality of the equipment, and through the driving of the fitting unit 43, the tilting The inclined plate 364 rotates along the circumferential end surface of the connecting section 61 and gradually stretches the hinged spring 365, so that the clamping strip 366 at the bottom of the inclined plate 364 is clamped on the inner wall of the annular groove of the connecting section 61. The clamping strip 366 is clamped on the inner wall of the annular groove to prevent the drill bit from shifting left and right when processing the inclined surface of the connecting section 61, thereby ensuring the processing quality and product performance of the graphite electrode 6. The clamping strip 366 can assist in clamping and fixing the electrode, further preventing the graphite electrode 6 from shifting during processing. Through multi-point clamping and fixing, the positioning accuracy and clamping effect during the drilling process are guaranteed.

[0046] like Figure 7 and Figure 8 As shown, the drilling mechanism 5 includes a control board 51, and the upper end surface of the upper inclined plate 364 is fixedly provided with a control board 51 that passes through from top to bottom, and the inclined plate 364 is provided with a control groove corresponding to the control board 51, and a drilling board 52 is slidably provided on the inner wall of the control board 51, and a drilling unit is provided on the drilling board 52 (the drilling unit includes a servo motor (not shown in the figure), a cooling pipe (not shown in the figure) and a drill bit 53 and other related equipment for drilling).

[0047] During operation, since the inclined plate 364 is parallel to the outer wall of the connecting section 61 of the graphite electrode 6, the axial position of the drill bit 53 remains perpendicular to the connecting section 61, and the drill bit 53 is driven by the drill plate 52 to slide up and down on the inner wall of the control plate 51 during drilling processing, and the connecting section 61 is drilled, so that the axis of the drilled electrode screw hole is synchronously perpendicular to the outer wall of the connecting section 61, which reduces the time for operators to correct and debug the axial direction of the electrode screw hole and improves production efficiency. Secondly, it avoids left and right deviation of the drill bit 53 during drilling, which damages the outer wall of the connecting section 61 and affects product quality and service life.

[0048] like Figure 5 , Figure 6 and Figure 7 As shown, the fitting unit 43 includes a driving gear 431, the rear end fixed sleeve of the worm 41 is provided with a driving gear 431, the inner cavity of the side seat 2 is rotatably provided with a screw rod 433 whose axis extends from left to right, the right side fixed sleeve of the screw rod 433 is provided with a driven gear 432, the driven gear 432 is meshed with the driving gear 431, and a moving block 434 is provided on the screw rod 433 for sliding left and right, the moving block 434 and the screw rod 433 are threadedly matched, the front side of the moving block 434 is fixedly provided with a support rod 435, the front side of the support rod 435 is fixedly provided with a pressure plate 436 with a cavity inside, and the pressure plate 436 is a truncated cone with a small left side and a large right side.

[0049] During operation, the external motor drives the worm 41 to rotate, the worm 41 drives the driving gear 431 to rotate, the driving gear 431 drives the meshing driven gear 432 to rotate, and the fixed gear drives the screw rod 433 to rotate, so that the moving block 434 slides on the screw rod 433, and the moving block 434 drives the support rod 435 to slide to the right synchronously, and the support rod 435 drives the pressure plate 436 to move, so that the left ends of the multiple inclined plates 364 gradually contact the inner cavity of the pressure plate 436, so that the hinged inclined plate 364 rotates along the inclined surface of the connecting section 61 until it is in contact with the circumferential outer wall of the connecting section 61.

[0050] like Figure 2 , Figure 3 and Figure 4As shown, the rotating unit 37 includes a rotating rod 371, a rotating rod 371 with an axis extending from right to left is fixedly provided on the left side of the connecting plate 341, and the rotating rod 371 slides through the fixed plate 32, and a limiting plate 33 is slidably provided on the fixed plate 32, and the rotating rod 371 is fixedly connected to the limiting plate 33, a moving spring 375 is commonly provided between the limiting plate 33 and the connecting plate 341, and the moving spring 375 is slidably sleeved on the rotating rod 371, a plurality of limiting grooves corresponding to the sliding plate 342 are equidistantly provided on the circumferential outer wall of the limiting plate 33, the rotating rod 371 is connected to an external motor 2 (not shown in the figure), a plurality of circumferentially evenly distributed ball grooves 374 are provided on the left end surface of the fixed plate 32, a square plate 372 is fixedly provided on the upper end of the rotating rod 371, and a round ball 373 corresponding to the ball groove 374 is fixedly provided on the right side of the square plate 372.

[0051] During operation, when different processing requirements need to be met, that is, when drilling holes at different angles of the same connecting section 61 is performed, the external motor 2 is used to drive the rotating rod 371 to rotate, and the rotating rod 371 drives the limiting plate 33 and the square plate 372 to rotate. When the square plate 372 drives the ball 373 to disengage from the ball groove 374, the ball 373 drives the square plate 372 to move to the left, and the square plate drives the rotating rod 371 to move synchronously, so that the rotating rod 371 drives the connecting plate 341 to move and gradually compresses the moving spring 375, and the limiting plate 33 drives the connecting plate 341 and the sliding plate 342 to move synchronously. The sliding plate 342 drives the fixing unit 35, the adjusting unit 36 ​​and the drilling mechanism 5 to rotate synchronously. After rotating to the required angle, the ball 373 fits against the inner wall of the ball groove 374, and the compressed moving spring 375 drives the rotating rod 371 and the connecting plate 341 to reset, so that the operator can rotate the angle of the drilling mechanism 5 without moving the equipment and the graphite electrode 6, and perform drilling processing on another angle of the same connecting section 61, thereby reducing the positioning error caused by the movement, improving the processing accuracy, and reducing the movement and positioning time of the graphite electrode 6, thereby improving the work efficiency.
