Description

Technical Field

[0001] The present application relates to the field of graphite electrode processing, and in particular to a positioning 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, the graphite electrodes need to be fixed first, usually using clamping and positioning tools to fix them, so as to prevent them from moving randomly during the processing, resulting in an increase in the scrap rate.

[0004] However, due to the brittle texture of graphite electrodes, the positioning method of clamping with a bench vise or tightening with bolts can easily damage the graphite electrodes and affect the quality of the graphite electrodes. Utility Model Content

[0005] In order to reduce damage to the graphite electrode when clamping and positioning it, the present application provides a positioning tool for graphite electrode processing.

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

[0007] A positioning tool for graphite electrode processing includes a base, a clamping assembly and two limit assemblies, wherein the clamping assembly is arranged on the base, the clamping assembly includes a driving member and two clamping rods, the two clamping rods are arranged opposite to each other, the driving member drives the two clamping rods to clamp the graphite electrode, mounting plates are arranged on opposite sides of the top of the base, the limit assemblies are arranged on the mounting plates and correspond to the mounting plates one by one, and are used to limit the displacement of the graphite electrode.

[0008] By adopting the above technical solution, the graphite electrode is placed on the base, the driving member is controlled to drive the two clamping rods to move towards each other to clamp the graphite electrode, and then the two limit assemblies are driven to move towards each other to limit the movement of the graphite electrode from another direction, thereby enhancing the positioning stability of the graphite electrode. In addition, the graphite electrode is fixed from multiple directions, and multiple parts of the graphite electrode are subjected to clamping force, thereby reducing the possibility of damage to the graphite electrode due to excessive clamping force at a certain part.

[0009] Optionally, the driving member includes a cylinder, a connecting rod, a support plate and two guide blocks. A receiving groove is provided on the top of the base, the cylinder is arranged in the receiving groove, one end of the connecting rod is fixedly connected to the movable end of the cylinder, and the other end is fixedly connected to the bottom of the support plate, the support plate is arranged above the base, the two guide blocks are arranged on the opposite side walls of the connecting rod, and are both located in the receiving groove, the two guide blocks correspond to the two clamping rods one by one, the middle part of each clamping rod is hinged to the base, the bottom of the clamping rod extends into the receiving groove and abuts against the side wall of the guide block, and the side wall where the guide block abuts against the clamping rod is inclined downward from the side close to the connecting rod to the side away from the connecting rod.

[0010] By adopting the above technical solution, the graphite electrode is placed on the support plate, the cylinder is controlled to extend its movable end, the connecting rod is driven to drive the two guide blocks to move upward, the bottom of the clamping rod moves away from each other along the side walls of the guide blocks, and the top of the clamping rod moves toward each other, thereby clamping the graphite electrode on the support plate for easy operation.

[0012] By adopting the above technical solution, after the clamping rod clamps the graphite electrode, the worker turns the handle, and the handle drives the push rod to rotate, driving the limit plate to move toward the direction close to the graphite electrode until it is tightly against the graphite electrode. After the two limit plates are in contact with the opposite sides of the graphite electrode, the positioning of the graphite electrode is completed. In terms of operation, the positioning is stable.

[0013] Optionally, a torsion spring is coaxially arranged on the hinge axis of the clamping rod.

One end of the air pump is connected to the connecting cavity, and the other end is connected to the dust collecting box.

[0018] By adopting the above technical solution, since a lot of debris will be generated during the processing of graphite electrodes, the air pump is started during processing to suck the debris into the dust collecting box through the connecting cavity and the dust suction hole, thereby reducing the pollution of the surrounding environment by the debris of the graphite electrode.

[0019] Optionally, anti-slip grooves are provided on the top of the clamping rod.

[0022] By adopting the above technical solution, when the graphite electrode is placed on the support plate, the curved surface can reduce the possibility of the graphite electrode rolling randomly on the support plate, thereby further improving the stability of the graphite electrode.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] Reference Figure 1 A positioning tool for graphite electrode processing disclosed in an embodiment of the present application includes a base 1, a clamping assembly 2, two limit assemblies 3 and two dust suction assemblies 4. The base 1 is a square body, and mounting plates 11 are fixedly installed on opposite sides of the top of the base 1 along the vertical direction. The clamping assembly 2 is arranged on the base 1, and the two limit assemblies 3 are arranged on the two mounting plates 11, and correspond one to one to the two mounting plates 11. The two dust suction assemblies 4 are also arranged on the base 1.

[0033] Reference Figure 1 and Figure 2 The clamping assembly 2 includes a driving member 21 and two clamping rods 22, wherein the driving member 21 includes a cylinder 211, a connecting rod 212, a support plate 213 and two guide blocks 214. A receiving groove 12 is provided at the top of the base 1. The cylinder 211 is fixedly installed at the bottom of the receiving groove 12 along the vertical direction. One end of the connecting rod 212 is fixedly connected to the movable end of the cylinder 211, and the other end is fixedly connected to the bottom of the support plate 213. The support plate 213 is located above the base 1, and the top of the support plate 213 is set to be a downwardly concave arc surface to reduce the possibility of the graphite electrode being placed on the support plate 213 and rolling at will. The two clamping rods 22 are located on opposite sides of the support plate 213, and the two guide blocks 214 are fixedly installed on the side walls on opposite sides of the connecting rod 212, and correspond to the two clamping rods 22 one by one.

[0034] In this embodiment, the two clamping rods 22 are both arc-shaped bent rods and are arranged opposite to each other in the vertical direction. The middle part of each clamping rod 22 is hinged to the inner wall of the accommodating groove 12, the top of the clamping rod 22 extends out of the accommodating groove 12, and the bottom of the clamping rod 22 abuts against the side wall of the guide block 214. The side wall where the guide block 214 abuts against the clamping rod 22 is inclined downward from the side close to the connecting rod 212 to the side away from the connecting rod 212.

[0035] Therefore, after placing the graphite electrode on the support plate 213, the cylinder 211 is controlled to extend its movable end, driving the connecting rod 212 to drive the two guide blocks 214 to move upward, and the bottom of the clamping rod 22 moves away from each other along the side walls of the guide blocks 214, while the top of the clamping rod 22 moves toward each other, thereby clamping the graphite electrode on the support plate 213.

[0036] In order to enhance the clamping stability of the clamping rod 22, the top of the clamping rod 22 is provided with an anti-slip groove 221 to increase the friction between it and the graphite electrode. The bottom of the clamping rod 22 is provided with a roller 222 to reduce the friction between the clamping rod 22 and the guide block 214.

[0037] In addition, a torsion spring 5 is coaxially mounted on the hinge shaft of the clamping rod 22, one end of the torsion spring 5 is fixedly connected to the clamping rod 22, and the other end is fixedly connected to the inner wall of the receiving groove 12. When the cylinder 211 is extended, the bottom ends of the two clamping rods 22 move away from each other along the side wall of the guide block 214, the torsion spring 5 is compressed, and the top ends of the two clamping rods 22 clamp the graphite electrode; when the graphite electrode is processed, the cylinder 211 is contracted, and the two clamping rods 22 rotate under the elastic reset action of the torsion spring 5, and the top ends of the two clamping rods 22 move away from each other, releasing the positioning clamping of the graphite electrode.

[0038] Each limiting assembly 3 includes a limiting plate 31, a push rod 32 and a handle 33. The limiting plate 31 is arranged between the support plate 213 and the mounting plate 11 in the vertical direction. The bottom of the limiting plate 31 fits the top of the base 1. One end of the push rod 32 is rotatably connected to the limiting plate 31, and the other end is fixedly connected to the handle 33. The push rod 32 is a threaded rod, which is threadedly connected to the mounting plate 11. The worker rotates the handle 33 to drive the push rod 32 to rotate, thereby driving the limiting plate 31 to move along the top of the base 1 and press against the graphite electrode.

[0039] Reference Figure 1 and Figure 3, two dust suction components 4 correspond to two limit plates 31 one by one, each dust suction component 4 includes an air pump 41 and a dust box 42. In this embodiment, the air pump 41 and the dust box 42 are both installed on the top of the base 1. A connecting cavity 311 is provided in the limit plate 31. A plurality of penetrating dust suction holes 312 are provided on the side wall of the connecting cavity 311 close to the support plate 213. One end of the air pump 41 is connected to the connecting cavity 311, and the other end is connected to the dust box 42. During processing, the air pump 41 is turned on, and the debris generated by processing the graphite electrode can be sucked into the dust box 42 through the dust suction holes 312 and the connecting cavity 311, reducing pollution to the surrounding environment.

[0040] The implementation principle of the positioning tool for graphite electrode processing in the embodiment of the present application is as follows: the worker first places the graphite electrode on the support plate 213, and then controls the movable end of the cylinder 211 to extend, and the bottom ends of the two clamping rods 22 move away from each other along the side wall of the guide block 214, the torsion spring 5 is compressed, and the top ends of the two clamping rods 22 move toward each other to clamp the graphite electrode. Then turn the handle 33, the handle 33 drives the push rod 32 to rotate, and drives the limit plate 31 to move toward the direction close to the graphite electrode until it is tightly against the graphite electrode, completing the positioning of the graphite electrode in multiple directions, and multiple parts of the graphite electrode will be subjected to clamping force, reducing the possibility of damage to the graphite electrode due to excessive clamping force at a certain part. When the graphite electrode is processed, the handle 33 is rotated in the opposite direction to drive the limit plate 31 to move away from the graphite electrode, and then the movable end of the cylinder 211 is controlled to shrink. The two clamping rods 22 rotate under the elastic reset action of the torsion spring 5, and the top ends of the two clamping rods 22 move away from each other, releasing the positioning clamping of the graphite electrode. The operation is simple and convenient.
