Description

Technical Field

[0001] This utility model belongs to the field of blade flaw detection technology, and in particular relates to an electrode angle adjustment and lead plate quick-change mechanism. Background Technology

[0002] Blades typically operate in harsh environments, such as high temperature, high pressure, and high speed. If there are minute defects on the surface and near the surface of the blade, such as cracks, inclusions, hairline cracks, white spots, or pores, they may pose serious safety hazards during blade operation. Magnetic particle testing can effectively detect blade defects.

[0003] However, the blades have complex shapes, especially the beveled portion at the blade tips. When using a fixed electrode head for flaw detection, the beveled portion at the blade tips cannot make complete contact with the electrode head, resulting in uneven circumferential current flow through the workpiece. This poor contact disrupts the uniform distribution of the magnetic field, preventing the magnetic powder from forming a clear magnetic trace at the defect, thus increasing the risk of missed defects. Therefore, to address these issues, the electrode angle adjustment and lead plate quick-change mechanism provided by this invention is of great significance. Utility Model Content

[0004] This invention provides an electrode angle adjustment and lead plate quick-change mechanism. By adjusting the electrode angle, it ensures that the current passes evenly through the workpiece, reducing problems such as arcing and burns or inaccurate test results caused by poor contact. Furthermore, the correct electrode angle can prevent arc discharge, reducing burns on the workpiece surface and equipment damage. Adjusting the electrode angle can also reduce false readings caused by uneven current density distribution, improving the accuracy and reliability of the test and reducing false readings and misjudgments. In addition, adjusting the electrode angle can better adapt to workpieces of different shapes, improving the flexibility of the test. By equipping the electrode plate with detachable arc-shaped stainless steel fixing plates, a 6-10mm lead plate can be clamped. The fixing plates can be quickly disassembled and replaced with bolts, reducing replacement time and improving test efficiency. The lead plate has low hardness, making it less likely to damage the workpiece surface during magnetization clamping. In summary, this invention solves the problems in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses an electrode angle adjustment and lead plate quick-change mechanism, including a mounting base, an electrode shaft fixedly connected to the mounting base, a slot at the end of the electrode shaft, threaded holes at the top and bottom of the slot, a fixing angle bolt threaded into the threaded hole, an electrode plate mounted at the end of the electrode shaft, a locking block fixedly connected to one side of the electrode plate, a copper plate mounted on the other side of the electrode plate, a lead plate mounted on one side of the copper plate, and fixing plates mounted at the top and bottom of the electrode plate.

[0007] Furthermore, the fixing plate is an arc-shaped stainless steel plate structure and adopts a detachable design. A threaded pipe is fixedly connected to the fixing plate, and the threaded pipe is connected to the fixing plate.

[0008] Furthermore, the fixed angle bolt is stepped, with its bottom diameter being equal to the diameter of the threaded hole, and the top diameter of the fixed angle bolt being larger than the diameter of the threaded hole.

[0009] Furthermore, the height of the card slot is equal to the thickness of the card block.

[0010] Furthermore, a V-shaped block is installed on the lead plate.

[0011] The present invention has the following advantages over the prior art:

[0012] (1) When using the electrode angle adjustment and lead plate quick-change mechanism of this utility model, the current can be made to pass through the workpiece evenly by adjusting the electrode angle, so as to reduce the problem of arcing and burning or inaccurate detection results caused by poor contact. Furthermore, the correct electrode angle can avoid arc discharge, thereby reducing the burn on the surface of the workpiece and equipment damage. Adjusting the electrode angle can also reduce false displays caused by uneven current density distribution, improve the accuracy and reliability of detection, and reduce false displays and misjudgments. In addition, adjusting the electrode angle can better adapt to workpieces of different shapes, thereby improving the flexibility of detection.

[0013] (2) When using the electrode angle adjustment and lead plate quick-change mechanism of this utility model, a 6-10mm lead plate can be pressed by detachable arc-shaped stainless steel fixing plates on the upper and lower parts of the electrode plate. The fixing plates can be quickly disassembled and replaced by bolts to reduce replacement time and improve detection efficiency. The lead plate has low hardness and is not easy to damage the workpiece surface when magnetized and clamped.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0023] Please see Figure 1-3 As shown, this utility model discloses an electrode angle adjustment and lead plate quick-change mechanism, including a mounting base 1. The mounting base 1 has mounting holes for mounting the mounting base 1 together with the entire mechanism on a fixed or movable housing. An electrode shaft 2 is fixedly connected to the mounting base 1. A slot 3 is provided at the end of the electrode shaft 2. Threaded holes are provided at the top and bottom of the slot 3. Fixed angle bolts 4 that cooperate with the threaded holes are threaded into the threaded holes. An electrode plate 5 is installed at the end of the electrode shaft 2. A locking block 6 is fixedly connected to one side of the electrode plate 5, and a copper plate 7 is installed on the other side of the electrode plate 5. A lead plate 8 is installed on one side of the copper plate 7. The lead plate 8 has low hardness and is not easy to damage the workpiece surface when magnetized and clamped. Fixing plates 9 are installed at the top and bottom of the electrode plate 5.

[0024] The fixing plate 9 is an arc-shaped stainless steel plate structure with a detachable design. A threaded tube 10 is fixedly connected to the fixing plate 9. The threaded tube 10 is connected to the fixing plate 9, and a fastening bolt that matches it can be screwed into the threaded tube 10. By tightening the fastening bolt in the threaded tube 10, the lead plate 8 of 6-10mm can be pressed to prevent the lead plate 8 from loosening. The fixing plate 9 can be quickly disassembled and replaced by bolts to reduce replacement time and improve testing efficiency.

[0025] The fixed angle bolt 4 is stepped, with its bottom diameter matching the diameter of the threaded hole, and its top diameter larger than the diameter of the threaded hole. Tightening the fixed angle bolt 4 can secure the locking block 6 in the locking slot 3 to fix the angle of the electrode plate 5. When the fixed angle bolt 4 is loosened, its stepped surface leaves the locking block 6, allowing the electrode plate 5 to rotate left and right (±15°) to adjust the electrode angle. Adjusting the electrode angle ensures that the current passes evenly through the workpiece, reducing problems such as arcing and burns or inaccurate test results caused by poor contact. A correct electrode angle can also prevent arc discharge, reducing burns on the workpiece surface and equipment damage. Adjusting the electrode angle can also reduce false displays caused by uneven current density distribution, improving the accuracy and reliability of the test and reducing false displays and misjudgments. Furthermore, adjusting the electrode angle can better adapt to workpieces of different shapes, improving the flexibility of the test.

[0026] The height of the slot 3 is equal to the thickness of the block 6. When the block 6 is inserted into the slot 3, its top and bottom surfaces can fit against the inner wall of the slot 3 so that the electrode plate 5 can be installed at the end of the electrode shaft 2 by means of insertion.

[0027] Among them, V-shaped blocks are installed on lead plate 8. The V-shaped blocks are designed according to the shape characteristics of the workpiece and can be used to stabilize and support the blades.

[0028] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon.

[0030] The working principle of this utility model is as follows:

[0031] In use, this invention can be mounted on the fixed housing at the left end and the movable housing at the rear end via mounting base 1. Before magnetization, the movable housing on the right end moves to the left end to a suitable distance from the workpiece via a gear and rack. Then, the workpiece is placed on the V-block on the lead plate 8, and the cylinder on the movable housing at the right end is driven to extend the electrode shaft 2 in the mechanism on the right side to clamp the workpiece. Next, the angle of the electrode plate 5 in the mechanism on the left side is rotated so that the blade tip bevel is perfectly aligned with the lead plate 8. After the clamping is stable, the screws can be tightened for fixation. Then, defects on the blade surface can be detected by magnetic particle inspection or other methods. This invention features an electrode angle adjustment and a quick-change lead plate structure. Through its application in magnetic particle inspection of blade workpieces, it significantly improves the accuracy, efficiency, and reliability of the inspection, providing a more flexible and efficient solution for the inspection of complex workpieces, ensuring the efficiency and accuracy of the inspection process.
