Description

Technical Field

[0001] The present application relates to the field of graphite electrode processing, and in particular to a clamping tool for graphite electrode processing. Background Art

[0002] Graphite electrode refers to a high-temperature resistant graphite conductive material made from petroleum coke and asphalt coke as aggregates and coal tar as binder, through the process of raw material calcination, crushing and grinding, batching, kneading, molding, roasting, impregnation, graphitization and mechanical processing.

[0003] When processing graphite electrodes, it is necessary to first use tooling to clamp the graphite electrodes so that they cannot move at will, and then use processing equipment to process them.

[0004] However, the existing clamping tool can only clamp one graphite electrode. After the graphite electrode is processed, it needs to be removed and the unprocessed graphite electrode needs to be fixed on the tool for a new round of processing, which is inefficient. Utility Model Content

[0005] In order to improve the processing efficiency of graphite electrodes, the present application provides a clamping tool for graphite electrode processing.

[0006] The present application provides a clamping tool for graphite electrode processing, which adopts the following technical solution:

[0007] A clamping tool for graphite electrode processing, comprising a base, a drive assembly, a clamping assembly and a limit assembly, wherein a rotating disk is arranged on the top of the base, the drive assembly drives the rotating disk to rotate, a plurality of clamping assemblies are arranged and all are arranged on the top of the rotating disk for clamping the graphite electrode, and the limit assembly corresponds to the clamping assembly one by one and is arranged on the top of the rotating disk for limiting the displacement of the graphite electrode.

[0008] By adopting the above technical solution, the driving assembly is started, the rotating disk rotates, and the worker can manipulate the clamping assembly one by one to clamp the graphite electrode, and then press the limit assembly against the graphite electrode to limit the movement of the graphite electrode. The fixed graphite electrode rotates with the rotating disk to the processing equipment for processing. After the processing is completed, it rotates to the worker, who removes it and then fixes the unprocessed graphite electrode. The fixing and processing of the graphite electrode can be carried out at the same time, which improves the processing efficiency.

[0009] Optionally, the clamping assembly includes a pushing rod, a mounting rod, two connecting rods and two clamping plates, the length direction of the pushing rod is perpendicular to the length direction of the mounting rod, a clearance groove is provided on the side wall of the middle part of the pushing rod close to the pushing rod, the pushing rod is embedded in the clearance groove, the top of the pushing rod is fixedly connected with a hinge shaft, one end of the connecting rod is provided with a sliding groove connected to the hinge shaft in a sliding and hinged manner, and the other end is hinged to the mounting rod, the two connecting rods are hinged at opposite ends of the mounting rod, the two clamping plates correspond to the two connecting rods one by one, and the clamping plate is fixedly connected to one end of the connecting rod away from the pushing rod.

[0010] By adopting the above technical solution, the push rod is pressed toward the bottom of the give way groove, one end of the connecting rod will move with the hinge shaft and the push rod, and the other end of the connecting rod will drive the clamping plate to rotate accordingly, and the two clamping plates will rotate away from each other. At this time, the worker places the graphite electrode between the two clamping plates, and then pulls the push rod in the direction away from the bottom of the give way groove. The connecting rod will drive the clamping plates to rotate in the opposite direction, and the two clamping plates will clamp the graphite electrode, which is easy to operate.

[0011] Optionally, a return spring is provided in the give way groove, one end of the return spring is fixedly connected to the bottom wall of the give way groove, and the other end of the return spring is fixedly connected to the push rod.

[0012] By adopting the above technical solution, when the worker presses the push rod, the reset spring contracts, and the connecting rod can drive the clamping plate to rotate, making it convenient for the worker to place the graphite electrode; after the graphite electrode is placed, the worker releases the push rod, and the push rod will move in the opposite direction under the elastic reset action of the reset spring, so that the connecting rod drives the clamping plate to rotate in the opposite direction, clamping the graphite electrode, further facilitating the worker's operation.

[0013] Optionally, a support column is fixedly installed on the top of the base, the support column is coaxially arranged with the rotating disk, a guide disk is coaxially eccentrically arranged on the top of the support column, and the end of the push rod away from the mounting rod abuts against the side wall of the guide disk.

[0014] By adopting the above technical solution, as the rotating disk rotates, when the push rod rotates to the side of the guide disk away from its own rotating axis, the push rod is pressed to the bottom of the give way groove. At this time, the two clamping plates rotate away from each other, and the worker places the graphite electrode between the two clamping plates. The rotating disk continues to rotate. When the push rod rotates to the side of the guide disk close to its own rotating axis, under the elastic reset action of the reset spring, the push rod moves in the direction away from the bottom of the give way groove, and the two clamping plates clamp the graphite electrode. The setting of the guide disk can replace the worker's operation of the push rod, shorten the time for fixing the graphite electrode, and improve processing efficiency.

[0015] Optionally, the limiting assembly includes a rotating rod and a limiting plate, a fixed plate is provided at the top edge of the rotating disk, the rotating rod is threadedly connected to the fixed plate, the limiting plate is provided on a side of the fixed plate close to the clamping plate, and the rotating rod is rotatably connected to the limiting plate.

[0016] By adopting the above technical solution, when a worker places a graphite electrode, he or she puts one end of the graphite electrode against the mounting rod, and then rotates the rotating rod to drive the limit plate to move toward the graphite electrode until it is pressed against the graphite electrode, thereby preliminarily fixing the graphite electrode and reducing the possibility of the graphite electrode moving at will when the clamping plate is clamped.

[0017] Optionally, the driving assembly includes a motor, a driving gear and a driven gear, the motor is fixedly mounted on the top of the base, the driving gear is coaxially fixedly connected to the output shaft of the motor, and the driven gear is coaxially fixedly connected to the rotating disk and meshingly connected to the driving gear.

[0018] By adopting the above technical solution, the motor is started, the motor output shaft drives the driving gear to rotate, and the driving gear drives the driven gear to drive the rotating disk to rotate, and the structure is simple and compact.

[0019] Optionally, a guide groove is provided on the side wall of the guide plate, and one end of the push rod away from the mounting rod is slidably connected in the guide groove.

[0020] By adopting the above technical solution, the push rod is always located in the guide groove during the movement of the rotating disk, thereby ensuring that the push rod can control the opening and closing of the clamping plate under the drive of the guide disk.

[0021] Optionally, a handle is fixedly mounted on one end of the rotating rod away from the limiting plate.

[0022] By adopting the above technical solution, workers can grasp the handle and twist the rotating rod to drive the limit plate to move, which is more convenient and labor-saving.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Start the drive assembly, the rotating disk rotates, and the worker can manipulate the clamping assembly one by one to clamp the graphite electrode, and then press the limit assembly against the graphite electrode to limit the movement of the graphite electrode. The fixed graphite electrode rotates with the rotating disk to the processing equipment for processing. After the processing is completed, it rotates to the worker, who removes it and then fixes the unprocessed graphite electrode. The fixing and processing of the graphite electrode can be carried out at the same time to improve the processing efficiency;

[0025] 2. As the rotating disk rotates, when the push rod rotates to the side of the guide disk away from its own rotating axis, the push rod is pressed to the bottom of the clearance groove. At this time, the two clamping plates rotate away from each other. The worker places the graphite electrode between the two clamping plates. The rotating disk continues to rotate. When the push rod rotates to the side of the guide disk close to its own rotating axis, under the elastic reset action of the reset spring, the push rod moves away from the bottom of the clearance groove. The two clamping plates clamp the graphite electrode. The setting of the guide disk can replace the worker's operation of the push rod, shorten the time for fixing the graphite electrode, and further improve the processing efficiency.

[0026] 3. When workers place the graphite electrode, they place one end of the graphite electrode against the mounting rod, and then rotate the rotating rod to drive the limit plate to move toward the graphite electrode until it is pressed against the graphite electrode, thereby preliminarily fixing the graphite electrode and reducing the possibility of the graphite electrode moving at will when the clamping plate is clamped.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] Reference Figure 1A clamping tool for graphite electrode processing disclosed in an embodiment of the present application includes a base 1, a drive component 2, a clamping component 3 and a limit component 4. The base 1 is a cylinder, and the drive component 2 is arranged on the top of the base 1. A support column 11 is coaxially fixedly connected to the top of the base 1. The support column 11 is also a cylinder. The upper part of the support column 11 is coaxially rotatably connected to a rotating disk 12. Multiple clamping components 3 and limit components 4 are provided, and they correspond one to one. The clamping components 3 and the limit components 4 are circumferentially arranged on the top of the rotating disk 12 along the axis of the rotating disk 12.

[0034] Reference Figure 1 and Figure 2 The driving assembly 2 includes a motor 21, a driving gear 22 and a driven gear 23. The motor 21 is fixedly mounted on the top of the base 1. The output shaft of the motor 21 is fixedly connected to the driving gear 22. The driven gear 23 is coaxially fixedly connected to the rotating disk 12 and meshed with the driving gear 22. In this embodiment, the driven gear 23 is sleeved and rotatably connected to the support column 11.

[0035] Reference Figure 1 , Figure 3 and Figure 4 The clamping assembly 3 includes a push rod 31, a mounting rod 32, two connecting rods 33 and two clamping plates 34. The extension direction of the push rod 31 is perpendicular to the extension direction of the mounting rod 32. The push rod 31 is arranged on the side of the mounting rod 32 close to the axis of the rotating disk 12. A clearance groove 321 is provided on the side wall of the middle part of the mounting rod 32. A return spring 5 is installed in the clearance groove 321. One end of the return spring 5 is fixedly connected to the inner bottom wall of the clearance groove 321, and the other end is fixedly connected to one end of the push rod 31. A hinge shaft 311 is fixedly connected to the top of the push rod 31. A sliding groove 331 is provided at one end of each connecting rod 33 close to the push rod 31 along its own extension direction. The hinge shaft 311 is installed in the sliding groove 331 in a sliding and hinged manner. The end of the connecting rod 33 away from the hinge shaft 311 is hinged to the mounting rod 32. It should be noted that the two connecting rods 33 are hinged to the opposite ends of the mounting rod 32 respectively. The clamping plate 34 is fixedly connected to one end of the connecting rod 33 away from the hinge shaft 311 .

[0036] A guide plate 6 is eccentrically installed on the top of the support column 11. In the present embodiment, the guide plate 6 is a cam, which is arranged above the rotating plate 12. A guide groove 61 is provided on the side wall of the guide plate 6, and the end of the push rod 31 away from the mounting rod 32 is slidably connected in the guide groove 61.

[0037] Therefore, as the rotating disk 12 rotates, when the push rod 31 rotates to the side of the guide disk 6 away from its own rotation axis, the push rod 31 is pressed to the bottom of the clearance groove 321, and one end of the connecting rod 33 moves with the hinge shaft 311 and the push rod 31, and the other end of the connecting rod 33 drives the clamping plate 34 to rotate accordingly. At this time, the two clamping plates 34 rotate in a direction away from each other, and the worker places the graphite electrode between the two clamping plates 34. The rotating disk 12 continues to rotate, and when the push rod 31 rotates to the side of the guide disk 6 close to its own rotation axis, under the elastic reset action of the reset spring 5, the push rod 31 moves in a direction away from the bottom of the clearance groove 321, and the connecting rod 33 drives the clamping plates 34 to rotate in the opposite direction, and the two clamping plates 34 clamp the graphite electrode.

[0038] The limiting assembly 4 includes a rotating rod 41 and a limiting plate 42. A fixed plate 121 is fixedly connected to the top edge of the rotating disk 12 in the vertical direction. The rotating rod 41 is threadedly connected to the fixed plate 121. One end of the rotating rod 41 is rotatably connected to the limiting plate 42, and the other end is fixedly installed with a handle 7. The limiting plate 42 is arranged on one side of the fixing plate 121 close to the clamping plate 34, and the bottom of the limiting plate 42 is in contact with the top of the rotating disk 12.

[0039] The implementation principle of the clamping tool for graphite electrode processing in the embodiment of the present application is as follows: when processing the graphite electrode, the motor 21 is started, the output shaft of the motor 21 drives the driving gear 22 to rotate, and the driving gear 22 drives the driven gear 23 to drive the rotating disk 12 to rotate. When the push rod 31 rotates with the rotating disk 12 to the side of the guide disk 6 away from its own rotating axis, the push rod 31 is pressed to the bottom of the clearance groove 321, and one end of the connecting rod 33 moves with the hinge shaft 311 and the push rod 31, and the other end of the connecting rod 33 drives the clamping plate 34 to rotate accordingly. At this time, the two clamping plates 34 rotate in a direction away from each other, which is convenient for workers to place the graphite electrode between the two clamping plates 34. When placing the graphite electrode, one end of it is pressed against the mounting rod 32, and then the handle 7 is turned to drive the rotating rod 41 to rotate, driving the limit plate 42 to move in the direction close to the graphite electrode until it is pressed against it.

[0040] The rotating disk 12 continues to rotate, and when the push rod 31 rotates to the side of the guide disk 6 close to its own rotating axis, the push rod 31 moves away from the bottom of the clearance groove 321 under the elastic reset action of the reset spring 5, and the connecting rod 33 drives the clamping plate 34 to rotate in the opposite direction. The two clamping plates 34 clamp the graphite electrode to complete the fixation of the graphite electrode. The processing and fixation of the graphite electrode can be carried out simultaneously, and the operation of the workers is simple, which greatly improves the processing efficiency of the graphite electrode.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
