Description

Technical Field

[0001] This utility model relates to the field of graphite electrode detection technology, and in particular to a clamping device for graphite electrode detection. Background Technology

[0002] In industrial production, graphite electrodes are widely used in electric arc furnace steelmaking, submerged arc furnaces and other fields. Because graphite electrodes need to withstand harsh conditions such as high temperature and strong current during use, their quality and performance directly affect the efficiency and safety of production. In order to ensure the quality of graphite electrodes, various tests are required, such as appearance inspection, dimensional inspection, resistivity testing, and compressive strength testing.

[0003] Existing technologies, such as the utility model with publication number CN219625421U, disclose a clamping device for graphite electrode detection. This patent uses a clamp, and an adjustment mechanism is provided above the clamp. The adjustment mechanism includes a rotating block, a movable groove, a movable rod, a connecting rod, a clamp, a limiting groove, and a limiting rod. This graphite electrode testing clamping device is equipped with an adjustment mechanism. When clamping and testing a graphite electrode, the rotating block can be pulled first. Under the action of the rotating block, the clamping fixture is rotated and adjusted. This avoids the problem that the clamping device is fixed after clamping the graphite electrode. Therefore, when it is necessary to test different parts of the graphite electrode, it is necessary to loosen the graphite electrode and then re-clamp it, which is time-consuming and laborious. At the same time, the rotating block is fixed by inserting a movable rod into the movable groove, and the clamping fixture can be installed by inserting a limiting rod into the limiting groove. This solves the problem that traditional graphite electrode testing clamping devices are fixed after clamping the graphite electrode. Therefore, when it is necessary to test different parts of the graphite electrode, it is necessary to loosen the graphite electrode and then re-clamp it, which is time-consuming and laborious.

[0004] In existing graphite electrode testing equipment, such as the one mentioned above, the graphite electrodes lack stable support during testing and are easily disturbed by external factors, causing them to shake. This shaking makes the contact between the measuring probe and the electrode unstable, resulting in a large error in the resistance measurement. Consequently, when inspecting the appearance of a motor, the difference in the observation angle and position may lead to deviations in the judgment of surface defects, causing some minor defects to be missed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the prior art, graphite electrodes lack stable support during testing and are easily disturbed by external factors, causing them to shake. This shaking can lead to unstable contact between the measuring probe and the electrode, resulting in large errors in resistance measurement. Consequently, when inspecting the appearance of a motor, differences in the observation angle and position may cause deviations in the judgment of surface defects, potentially causing some minor defects to be missed. Therefore, this invention proposes a clamping device for graphite electrode testing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a clamping device for graphite electrode detection, comprising a clamp, an adjustment mechanism, and a clamping assembly. The adjustment assembly is fixedly installed on the upper surface of the clamp, and a telescopic mechanism is fixedly provided on the lower surface of the clamp. A base plate is fixedly connected to the side of the telescopic mechanism away from the clamp. The clamping assembly is disposed on the lower surface of the base plate. The clamping assembly includes a mounting groove. The lower surface of the base plate has a mounting groove. A guide rail is fixedly connected to the inner wall of the mounting groove. The guide rail is convex and there are two guide rails. The two guide rails are symmetrically arranged at the center of the base plate.

[0007] Preferably, the inner wall of the guide rail is slidably connected to a slider, the slider is H-shaped, and there are two sliders. The two sliders are located at the center of the guide rail and are symmetrically arranged from left to right. The guide rail facilitates the guidance of the slider's sliding direction to ensure that the slider moves in a horizontal direction.

[0008] Preferably, a clamping plate is fixedly connected to the upper surface of the slider, and a rubber pad is fixedly connected to the side of the clamping plate near the electrode. The rubber pad is in contact with the upper surface of the base plate and abuts against the outer surface of the electrode. There are two rubber pads, which are symmetrically arranged at the center of the electrode. The rubber pads help protect the clamping plate when clamping the electrode to prevent the electrode from being damaged by friction during clamping.

[0009] Preferably, a mounting bracket is fixedly connected to the lower surface of the slider. A circular hole is opened on the surface of the mounting bracket. A connecting arm is rotatably connected to the inner wall of the circular hole. Both ends of the connecting arm are arc-shaped. There are two connecting arms, which are symmetrically arranged at the center of the guide rail. The connecting arms facilitate the synchronous movement of the sliders on both sides to ensure the uniformity of the movement of the sliders on both sides.

[0010] Preferably, a mounting bracket is fixedly connected to the lower surface of the base plate. The mounting bracket is L-shaped, and a cylinder is fixedly connected to the upper surface of the mounting bracket. A linkage block is fixedly connected to the driving end of the cylinder. The linkage block is rectangular. The mounting bracket facilitates the support of the cylinder's position to ensure the stability of the cylinder during operation.

[0011] Preferably, a connecting frame is fixedly connected to the side surface of the linkage block. The surface of the connecting frame is provided with a rotating hole. The connecting frame is rotatably connected to a connecting arm on the inner wall of the rotating hole. There are two connecting frames, which are symmetrically arranged at the center of the linkage block. The connecting frame facilitates the connection between the linkage block and the connecting arm, ensuring that the cylinder can drive the connecting arm to move in the driving state.

[0012] Preferably, a limiting block is fixedly connected to the side of the mounting bracket near the cylinder. The limiting block is in contact with the surface of the cylinder. An installation sleeve is fixedly connected to the inner wall of the limiting block. A cleaning brush is fixedly connected to the inner wall of the installation sleeve. The cleaning brush is in contact with the drive shaft of the cylinder. There are multiple cleaning brushes, which are arranged in a circumferential array at the axis of the drive shaft of the cylinder. The cleaning brush facilitates the cleaning of dust generated on the drive shaft of the cylinder, thereby ensuring the cleanliness of the cylinder drive shaft.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this utility model, by setting up a clamping component, when it is necessary to clamp the graphite electrode, the operator turns on the cylinder switch clockwise, the cylinder is powered on and drives the linkage block, and then the cylinder pushes the linkage block to move upward. The linkage block moves upward and pushes the connecting arm. Then the connecting arms on both sides move upward with the linkage block and gradually unfold to both sides. The unfolded connecting arms cooperate with the mounting frame, and drive the slider to move to both sides synchronously under the guidance of the guide rail. When the clamping plate moves to the middle distance, which is large enough to fit the graphite electrode, the servo motor switch can be turned off and the servo motor stops working. Then the graphite electrode can be placed in the middle of the clamp.

[0015] Once placement is complete, the cylinder switch can be turned counterclockwise, energizing the cylinder and causing it to move downwards. Simultaneously, the moving block, in conjunction with the connecting frame, pulls the connecting arm downwards. The connecting arm then moves the slider and clamping plate along the guide rail until the rubber pad clamps the graphite electrode. The cylinder switch can then be turned off, stopping the cylinder's operation. The clamping mechanism can then be turned on to inspect the graphite electrode. By incorporating the clamping components, a stable support and reliable clamping force are provided for the graphite electrode, keeping it stationary during inspection and preventing deviations in the inspection data due to shaking or displacement, thus further improving the accuracy of graphite electrode inspection.

Detailed Implementation

[0024] Please see Figures 1-6This utility model provides a technical solution: a clamping device for detecting graphite electrodes, including a clamp 1, an adjustment mechanism 2 and a clamping component 5. The adjustment component is fixedly installed on the upper surface of the clamp 1, and a telescopic mechanism 3 is fixedly provided on the lower surface of the clamp 1. A base plate 4 is fixedly connected to the side of the telescopic mechanism 3 away from the clamp 1, and the clamping component 5 is provided on the lower surface of the base plate 4.

[0025] In this embodiment: the clamping component 5 includes a mounting groove 51. The mounting groove 51 is provided on the lower surface of the base plate 4. A guide rail 52 is fixedly connected to the inner wall of the mounting groove 51. The guide rail 52 is convex and there are two guide rails 52. The two guide rails 52 are located at the center of the base plate 4 and are arranged symmetrically from left to right.

[0026] Specifically, the inner wall of the guide rail 52 is slidably connected to a slider 53. The slider 53 is H-shaped and there are two sliders 53. The two sliders 53 are located at the center of the guide rail 52 and are arranged symmetrically from left to right.

[0027] The effect achieved by the above components is that the guide rail 52 facilitates the direction of sliding of the slider 53, so as to ensure that the slider 53 moves in a horizontal direction.

[0028] Specifically, a clamping plate 54 is fixedly connected to the upper surface of the slider 53, and a rubber pad 55 is fixedly connected to the side of the clamping plate 54 near the electrode. The rubber pad 55 is in contact with the upper surface of the base plate 4 and abuts against the outer surface of the electrode. There are two rubber pads 55, which are symmetrically arranged at the center of the electrode.

[0029] The effect achieved by the above components is that the rubber pad 55 facilitates the clamping plate 54 to protect the electrode when clamping it, so as to prevent the electrode from being damaged by friction during clamping.

[0030] Specifically, a mounting bracket 56 is fixedly connected to the lower surface of the slider 53. A circular hole is opened on the surface of the mounting bracket 56. A connecting arm 57 is rotatably connected to the inner wall of the circular hole. Both ends of the connecting arm 57 are arc-shaped. There are two connecting arms 57, which are symmetrically arranged at the center of the guide rail 52.

[0031] The effect achieved by the above components is that the connecting arm 57 facilitates the synchronous movement of the sliders 53 on both sides, so as to ensure the uniformity of the movement of the sliders 53 on both sides.

[0032] Specifically, a mounting bracket 58 is fixedly connected to the lower surface of the base plate 4. The mounting bracket 58 is L-shaped. A cylinder 59 is fixedly connected to the upper surface of the mounting bracket 58. A linkage block 510 is fixedly connected to the drive end of the cylinder 59. The linkage block 510 is rectangular.

[0033] The effect achieved by the above components is that the mounting bracket 58 facilitates the support of the position of the cylinder 59, thereby ensuring the stability of the cylinder 59 in the working state.

[0034] Specifically, a connecting frame 511 is fixedly connected to the side surface of the linkage block 510. A rotating hole is opened on the surface of the connecting frame 511. A connecting arm 57 is rotatably connected to the inner wall of the rotating hole. There are two connecting frames 511, which are symmetrically arranged at the center of the linkage block 510.

[0035] The effect achieved by the above components is that the connecting bracket 511 facilitates the connection between the linkage block 510 and the connecting arm 57, so as to ensure that the cylinder 59 can drive the connecting arm 57 to move in the driving state.

[0036] Specifically, a limiting block 512 is fixedly connected to the side of the mounting bracket 58 near the cylinder 59. The limiting block 512 is in contact with the surface of the cylinder 59. An mounting sleeve 513 is fixedly connected to the inner wall of the limiting block 512. A cleaning brush 514 is fixedly connected to the inner wall of the mounting sleeve 513. The cleaning brush 514 is in contact with the drive shaft of the cylinder 59. There are multiple cleaning brushes 514, which are arranged in a circular array at the center of the drive shaft of the cylinder 59.

[0037] The effect achieved by the above components is that the cleaning brush 514 facilitates the cleaning of dust generated on the drive shaft of cylinder 59, thereby ensuring the cleanliness of the drive shaft of cylinder 59.

[0038] Working principle: When the graphite electrode needs to be clamped, the operator turns on the switch of cylinder 59 clockwise. Cylinder 59 is powered on and drives linkage block 510. Then cylinder 59 pushes linkage block 510 to move upward. Linkage block 510 moves upward and pushes connecting arm 57. Then the connecting arms 57 on both sides move upward with linkage block 510 and gradually unfold to both sides. When the connecting arms 57 unfold, they cooperate with mounting bracket 56, and drive slider 53 to move to both sides synchronously under the guidance of guide rail 52. When the clamping plate 54 moves to the middle distance, which is large enough to fit the graphite electrode, the switch of servo motor can be turned off and the servo motor stops working. Then the graphite electrode can be placed in the middle of clamp 1.

[0039] Once placement is complete, the switch of cylinder 59 can be turned counterclockwise, energizing cylinder 59 and causing linkage block 510 to move downwards. As linkage block 510 moves, it cooperates with connecting frame 511 to pull down connecting arm 57. Connecting arm 57 then moves slider 53 and clamping plate 54 to the middle of guide rail 52 until rubber pad 55 clamps the graphite electrode. Then, the switch of cylinder 59 can be turned off, stopping cylinder 59. The switch of clamp 1 can then be turned on to test the graphite electrode. By setting clamping component 5, a stable support and reliable clamping force can be provided for the graphite electrode, keeping it stationary during the test and avoiding deviations in test data due to shaking or displacement, thus further improving the accuracy of graphite electrode testing.
