Description

Technical Field

[0001] The utility model relates to the technical field of graphite electrode fixtures, in particular to a graphite electrode blank inlet and outlet fixture. Background Art

[0002] Graphite electrodes are mainly made of petroleum coke and needle coke as raw materials, coal tar as a binder, and are made through calcination, batching, kneading, pressing, roasting, graphitization and machining.

[0003] The existing Chinese patent with publication number CN 213976641 U discloses a graphite electrode clamp device, including a support plate, a slide groove is provided at the bottom of the support plate, a first threaded rod is movably connected between the left and right ends of the inner cavity of the slide groove, a servo motor is fixedly installed at the right end of the support plate, the motor shaft of the servo motor is fixedly connected to the first threaded rod, two identical sliders are spirally sleeved on the outer wall of the first threaded rod, and the bottoms of the two sliders are fixedly connected with clamps. The utility model starts the servo motor through the arrangement of the servo motor, the slide groove, the slider, the first threaded rod, the clamp and the truncated cone column, thereby driving the two clamps to move toward each other. Since the graphite electrode is a hollow structure, the truncated cone column is placed in the inner cavity at the left and right ends of the graphite electrode, and the graphite electrode can be further clamped.

[0004] However, the above patent still has some shortcomings. Since a truncated cone column is provided for clamping, the contact surface between the clamp and the graphite electrode is small, which may easily cause damage to the contact part. Furthermore, if the clamp is not in place, a gap will be created between the truncated cone column and the inner cavity of the graphite electrode, causing the graphite electrode to shake during hoisting. Utility Model Content

[0005] In order to solve the deficiencies mentioned in the above background technology, the purpose of the utility model is to provide a graphite electrode blank in and out of the furnace clamp, which is sleeved on the inner rod by a sleeve rod, and the spring is located between the clamp and the sleeve rod. When the sleeve rod is squeezed by the graphite electrode, the sleeve rod will move outward along the inner rod, and the spring will be compressed. In this way, the adaptive fixing component can automatically adjust the clamping force according to the inner diameter of the graphite electrode to ensure the stability and safety of the clamping.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A graphite electrode blank in-and-out fixture comprises a hanger, a guard plate is symmetrically arranged at the bottom end of the hanger, a screw is arranged between two guard plates, the screw is a double-threaded screw, one end of the screw passes through one side guard plate, a rotating motor is installed on one side of the guard plate, the output end of the rotating motor is fixedly connected to the screw, a driving block is threadedly connected to the screw, a limiting rod is fixedly connected between the two guard plates, the limiting rod passes through the driving block, the driving block and the limiting rod are slidably connected, a clamp is fixedly connected to the bottom end of the driving block, and an adaptive fixing component is arranged on the side where the two clamps are close to each other. Start the rotating motor, and the output end of the rotating motor drives the screw to rotate. Since the screw is a double-threaded screw, when the screw rotates, the two driving blocks will move towards or away from each other at the same time. This design makes the clamping and loosening actions of the clamp more rapid and stable.

[0008] Further preferably, the adaptive fixing assembly includes an inner rod and a sleeve rod, the sleeve rod is sleeved on the inner rod, the inner rod is sleeved with a spring, and the spring is located between the clamping plate and the sleeve rod. Since the sleeve rod is sleeved on the inner rod and the spring is located between the clamping plate and the sleeve rod, when the sleeve rod is squeezed by the graphite electrode, the sleeve rod will move outward along the inner rod, and the spring will be compressed. In this way, the adaptive fixing assembly can automatically adjust the clamping force according to the inner diameter of the graphite electrode to ensure the stability and safety of the clamping.

[0009] Further preferably, a connecting block is provided on the sleeve rod, connecting rods are symmetrically provided on the connecting block, and a support frame is rotatably connected between the two connecting rods.

[0010] Further preferably, the support frame and the connecting rod are parallel to each other, the two connecting rods are parallel to each other, and a plurality of the connecting blocks and support frames are provided, and are distributed in a circular array around the sleeve rod. The support frame also plays a key role in the clamping process. Since the support frame and the connecting rod can rotate, when the support frame contacts the inner wall of the graphite electrode, it will automatically adjust the angle according to the shape of the graphite electrode, thereby providing more stable support. At the same time, multiple support frames are distributed in a circular array around the sleeve rod, which can ensure that the graphite electrode is evenly supported in all directions.

[0011] Further preferably, an angle rod is fixedly connected to the inner rod, a limiting groove is provided inside the sleeve rod, and the angle rod is located in the limiting groove. Such a design limits the circumferential angle between the sleeve rod and the inner rod.

[0012] Further preferably, when the support frame is in the initial position, the distance between the end of the support frame away from the clamping plate and the clamping plate is smaller than the distance between the end of the sleeve rod away from the clamping plate and the clamping plate. Such an arrangement enables the sleeve rod to be squeezed first.

[0013] Beneficial effects of the utility model:

[0014] 1. The utility model is provided with a sleeve rod on the inner rod, and the spring is located between the clamping plate and the sleeve rod. When the sleeve rod is squeezed by the graphite electrode, the sleeve rod will move outward along the inner rod, and the spring will be compressed. In this way, the adaptive fixing component can automatically adjust the clamping force according to the inner diameter of the graphite electrode to ensure the stability and safety of the clamping;

[0015] 2. The utility model drives the screw to rotate by rotating the output end of the motor. Since the screw is a double-threaded screw, when the screw rotates, the two drive blocks will move towards or away from each other at the same time. This design makes the clamping and loosening actions of the splint more rapid and stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0025] like Figure 1-4 As shown, a graphite electrode blank in-and-out fixture comprises a hanger 1, a guard plate 2 is symmetrically arranged at the bottom end of the hanger 1, a screw 3 is arranged between two guard plates 2, the screw 3 is a double-threaded screw 3, one end of the screw 3 passes through one side guard plate 2, a rotating motor 4 is installed on one side of the guard plate 2, the output end of the rotating motor 4 is fixedly connected to the screw 3, a driving block 5 is threadedly connected to the screw 3, a limiting rod 6 is fixedly connected between the two guard plates 2, the limiting rod 6 passes through the driving block 5, the driving block 5 and the limiting rod 6 are slidably connected, a clamping plate 7 is fixedly connected to the bottom end of the driving block 5, and an adaptive fixing component is arranged on the side where the two clamping plates 7 are close to each other. Start the rotating motor 4, and the output end of the rotating motor 4 drives the screw 3 to rotate. Since the screw 3 is a double-threaded screw 3, when the screw 3 rotates, the two driving blocks 5 will move towards or away from each other at the same time. This design makes the clamping and loosening actions of the clamping plate 7 more rapid and stable.

[0026] The adaptive fixing assembly includes an inner rod 8 and a sleeve rod 9, wherein the sleeve rod 9 is sleeved on the inner rod 8, and a spring 11 is sleeved on the inner rod 8, and the spring 11 is located between the clamping plate 7 and the sleeve rod 9. Since the sleeve rod 9 is sleeved on the inner rod 8 and the spring 11 is located between the clamping plate 7 and the sleeve rod 9, when the sleeve rod 9 is squeezed by the graphite electrode, the sleeve rod 9 will move outward along the inner rod 8, and the spring 11 will be compressed. In this way, the adaptive fixing assembly can automatically adjust the clamping force according to the inner diameter of the graphite electrode to ensure the stability and safety of the clamping.

[0027] The sleeve rod 9 is provided with a connecting block 12 , and connecting rods 13 are symmetrically provided on the connecting block 12 , and a supporting frame 14 is rotatably connected between the two connecting rods 13 .

[0028] The support frame 14 and the connecting rod 13 are parallel to each other, and the two connecting rods 13 are parallel to each other. There are multiple connection blocks 12 and support frames 14, which are distributed in a circular array around the sleeve rod 9. The support frame 14 also plays a key role in the clamping process. Since the support frame 14 and the connecting rod 13 can rotate, when the support frame 14 contacts the inner wall of the graphite electrode, it will automatically adjust the angle according to the shape of the graphite electrode, thereby providing more stable support. At the same time, multiple support frames 14 are distributed in a circular array around the sleeve rod 9, which can ensure that the graphite electrode is evenly supported in all directions.

[0029] An angle rod 15 is fixedly connected to the inner rod 8, and a limiting groove 16 is provided inside the sleeve rod 9, and the angle rod 15 is located in the limiting groove 16. Such a design limits the circumferential angle between the sleeve rod 9 and the inner rod 8.

[0030] When the support frame 14 is in the initial position, the distance between the end of the support frame 14 away from the clamping plate 7 and the clamping plate 7 is smaller than the distance between the end of the sleeve rod 9 away from the clamping plate 7 and the clamping plate 7. Such an arrangement allows the sleeve rod 9 to be squeezed first.

[0031] Working principle:

[0032] When using the graphite electrode blank in-and-out fixture provided by the present invention, first, the fixture is hoisted above the graphite electrode by the hanger 1. Then, the rotating motor 4 is started, and the output end of the rotating motor 4 drives the screw 3 to rotate. Since the screw 3 is a double-threaded screw 3, when the screw 3 rotates, the two driving blocks 5 will move towards or away from each other at the same time. This design makes the clamping and loosening actions of the clamping plate 7 faster and more stable.

[0033] As the driving block 5 moves, the clamping plate 7 will also move closer to the graphite electrode accordingly. When the clamping plate 7 contacts the graphite electrode, the adaptive fixing assembly starts to work. Since the sleeve rod 9 is sleeved on the inner rod 8, and the spring 11 is located between the clamping plate 7 and the sleeve rod 9, when the sleeve rod 9 is squeezed by the graphite electrode, the sleeve rod 9 will move outward along the inner rod 8, and the spring 11 will be compressed. In this way, the adaptive fixing assembly can automatically adjust the clamping force according to the inner diameter of the graphite electrode to ensure the stability and safety of the clamping.

[0034] During the clamping process, the support frame 14 also plays a key role. Since the support frame 14 and the connecting rod 13 can rotate, when the support frame 14 contacts the inner wall of the graphite electrode, it will automatically adjust the angle according to the shape of the graphite electrode, thereby providing more stable support. At the same time, multiple support frames 14 are distributed in a circular array around the sleeve rod 9, which can ensure that the graphite electrode is evenly supported in all directions.
