Description

Technical Field

[0001] The utility model relates to the technical field of coating thickness detection, and more specifically, to a structure for real-time detection of coating thickness under high temperature spraying. Background Art

[0002] Spraying technology is increasingly widely used in modern industry. It not only plays an important role in fields such as automobiles, aerospace, electronics, and construction, but also with the rise of emerging fields such as 3D printing, nanomaterials, and biomedicine, its market demand continues to grow. Accurate measurement of coating thickness is one of the key factors to ensure the quality of sprayed products, which directly affects the performance of the coating and the final effect of the product.

[0003] There are still obvious limitations in the existing coating thickness measurement. Especially when the workpiece has a special-shaped structure, due to the limitation of tooling clamping, it is very difficult to measure the coating thickness of the workpiece in real time and accurately. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a structure for real-time detection of coating thickness under high temperature spraying, solve the above technical problems, and improve the accuracy and reliability of measurement.

[0005] The utility model is realized through the following technical solutions: A real-time coating thickness detection structure under high temperature of plasma spraying includes a workpiece and a tooling for clamping the workpiece. A measuring piece is detachably connected to the tooling, and the surface of the measuring piece is flush with the spraying surface of the workpiece.

[0006] Further, the measuring piece is an L-shaped block. One end of the L-shaped block is bolted to the tooling, and the other end of the L-shaped block abuts against the end of the workpiece.

[0007] Preferably, a plurality of L-shaped blocks are evenly arranged along the outer edge of the workpiece.

[0008] Further, the measuring piece is an annular plate, and the enclosed shape and size of the detection surface of the annular plate are the same as the enclosed shape and size of the spraying surface of the workpiece.

[0009] Further, the material of the measuring piece is the same as that of the workpiece.

[0010] The utility model has at least the following advantages and beneficial effects: By detachably connecting the measuring piece to the tooling, making the surface of the measuring piece flush with the spraying surface of the workpiece, an equivalent simulation is constructed. By measuring the coating thickness of the measuring piece in real time under high temperature spraying, the measurement of the thickness, roughness, and multi-region step difference of the workpiece coating is correspondingly realized, replacing the destructive module interception of the workpiece coating, ensuring the consistency of the simulation, and improving the accuracy and reliability of the measurement.

[0017] Embodiment 1

[0018] As Figure 1As shown, in this embodiment, a structure for real-time detection of coating thickness under high-temperature spraying is mainly disclosed, which is suitable for plasma spraying, and the coating growth value of the workpiece 1 is measured in real time under high-temperature spraying. The structure comprises a workpiece 1 and a fixture 2 for clamping the workpiece 1, and the fixture 2 is detachably connected with a measuring piece 3, and the surface of the measuring piece 3 is flush with the spraying surface of the workpiece 1; specifically, in this embodiment, the workpiece 1 can be a cylindrical component, and the fixture 2 can be a circular clamping component provided by the workpiece 1, and the outer wall of the workpiece 1 is clamped by the fixture 2 to be fixed, and the inner wall of the workpiece 1 is measured. The surface is sprayed; the measuring piece 3 is made of the same material as the workpiece 1 and is processed by the same process method as the workpiece 1 to avoid interference from influencing factors, ensure the consistency of simulation, and improve the accuracy of measurement; in the prior art, due to the clamping limitation of the tooling 2, the coating thickness of the sprayed surface of the workpiece 1 cannot be detected in real time under the high temperature state of spraying, and it needs to be executed after the spraying is completed and cooled. In this embodiment, the measuring piece 3 is installed on the tooling 2, that is, an equivalent simulation is constructed near the workpiece 1, and the initial value of the measuring piece 3 needs to be recorded in advance before installation. Thickness, when spraying, it is only necessary to move the spraying area of ​​the original workpiece 1 outward for a distance to cover the measuring piece 3. Since the measuring piece 3 is placed on the outside of the workpiece 1, when measuring, it is only necessary to use a micrometer to measure and calculate the growth value compared with the initial thickness, which represents the real-time thickness value of the coating. After spraying, the measuring piece 3 can be easily disassembled and replaced; in addition, by installing the measuring piece 3, by measuring the coating thickness of the measuring piece 3 under high temperature, it is also possible to measure the roughness of the coating of the workpiece 1 and the step difference of the multi-region coating of the workpiece 1, replacing the destructive module interception of the coating of the workpiece 1 in the prior art; it should be noted that there is a gap between the measuring piece 3, the workpiece 1 and the tooling 2 for easy execution of the coating thickness measurement, avoiding interference with the measuring tool and ensuring the smooth measurement. During the spraying process, the coating thickness value of the measuring piece 3 recorded in real time should be 0.05mm~0.06mm larger than the required value; after spraying, the coating thickness of the workpiece 1 is measured by metallographic measurement and compared with the coating thickness measured during the spraying process to ensure that the error is within the range of 0.05mm~0.06mm.

[0019] Furthermore, in a specific implementation, the measuring piece 3 provided in the embodiment of the utility model is an L-shaped block, one end of the L-shaped block is bolted to the tooling 2, and the other end of the L-shaped block is abutted against the end of the workpiece 1; specifically, the L-shaped block is formed by bending after laser cutting; a plurality of L-shaped blocks are evenly arranged along the outer edge of the workpiece 1, and the coating thickness can be detected at different positions of the workpiece 1, thereby avoiding local measurement errors and improving the reliability of detection.

[0020] Embodiment 2

[0021] In this embodiment, the main structure is exactly the same as that of the first embodiment. The difference is that the measuring piece 3 is an annular piece, and the enclosed shape and size of the detection surface of the annular piece are the same as those of the enclosed shape and size of the spraying surface of the workpiece 1. That is, the edge of the workpiece 1 is flush with the spraying surface of the workpiece 1 to butt against the annular piece, which can measure and reflect the coating thickness of each part in the circumferential direction of the workpiece 1 to a certain extent.

[0022] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
