Description

Technical Field

[0001] The present application relates to the technical field of shipbuilding, and in particular to a coating thickness gauge metrology and calibration auxiliary tooling. Background Art

[0002] In the shipbuilding industry, coating thickness gauges are widely used and there are a large number of them. They are measuring tools used to measure the thickness of metal coatings. Seawater is highly corrosive. During construction, a coating is usually applied to the surface of the hull for corrosion protection. Different locations on the hull have different requirements for the thickness of the anti-corrosion coating. Coating thickness gauges are usually used to detect the thickness of the anti-corrosion coating. The performance and measurement capabilities of coating thickness gauges are crucial to the shipbuilding industry, because the coatings on ships are not only required to be anti-corrosive, but also have high requirements for fire protection. In order to ensure the stability of the measurement performance of the coating thickness gauge and the accuracy and reliability of the values, it is necessary to conduct metrological verification on it regularly.

[0003] In order to ensure the reliability of product quality, the coating thickness gauge needs to be calibrated in accordance with the specific requirements of the metrological verification regulations JJG818-2018 "Verification Regulations for Magnetic and Eddy Current Coating Thickness Measuring Instruments". The commonly used coating thickness gauge metrological standard detection device consists of a standard thickness sheet and a flat workbench. The original flat workbench can hold at most two standard thickness sheets, and when calibrating, three to five points evenly distributed within the instrument range need to be taken as the inspection points. In this way, there are the following problems: First, safety issues. When calibrating the coating thickness gauge on the existing basis, in order to meet the metrological requirements, it is necessary to switch back and forth between standard thickness sheets of different specifications on the flat workbench as the inspection points. During the switching process, there is friction between the standard thickness sheet and the flat workbench. During the friction process, it is easy to cause scratches on the standard thickness sheet, which eventually causes damage to the metrological standard. Second, quality issues. There are many coating thickness gauges, so the number of calibrations for coating thickness gauges is also high, and the frequency of using standard thickness sheets is high. Due to the high frequency of use, the friction frequency between the standard thickness sheet and the flat workbench is also correspondingly high. Frequent friction will inevitably affect the accuracy of the standard thickness sheet value, and the data of the coating thickness gauge needs to be adjusted according to the value of the standard thickness sheet. Therefore, the accuracy of the standard thickness sheet value directly affects whether the data of the coating thickness gauge being tested is reliable, which will affect the quality of the coating on site and thus fail to guarantee product quality. 3. Efficiency issues: Since the coating thickness gauge has high accuracy and a large number of them, the existing flat workbench needs to switch the standard thickness sheet back and forth during calibration, which is inefficient and will affect the measurement and calibration work.

[0004] Therefore, it is necessary to design a coating thickness gauge metrology and calibration auxiliary tooling to solve the above problems. Summary of the invention

[0005] In view of this, in order to overcome the defects of the prior art, the present invention provides a coating thickness gauge metrological calibration auxiliary tooling, which effectively solves the problems of safety hazards, low calibration quality and efficiency in the calibration of the existing coating thickness gauge.

[0006] According to the present invention, a coating thickness gauge metrology and calibration auxiliary tooling is provided, wherein the coating thickness gauge metrology and calibration auxiliary tooling comprises a workbench body and at least three calibration card slots, the workbench body comprises a work surface, at least three of the calibration card slots are arranged on the work surface in sequence and at intervals, each of the calibration card slots is provided with a slot portion, the slot portion is used to accommodate a standard thickness sheet, and the specifications of the standard thickness sheets accommodated by at least three of the calibration card slots are different.

[0009] Preferably, the slot portion is formed as an open slot, and when the standard thickness sheet is accommodated in the inspection card slot, the inspection area of ​​the standard thickness sheet is located in the open slot, so that the inspection area of ​​the standard thickness sheet is exposed.

[0010] Preferably, the number of the test card slots is five.

[0011] Preferably, the workbench body is formed as a rectangular plate, and the rectangular plate has a length of 220 mm, a width of 80 mm, and a thickness of 5 mm.

It solves the safety, quality and efficiency problems, and can effectively avoid scratches or even damage to the standard thickness sheet due to friction; standard thickness sheets of different specifications are placed in different calibration slots to ensure the precision and accuracy of the coating thickness gauge; since at least three inspection points can exist at the same time, there is no need to switch the standard thickness sheet back and forth, and friction damage to the standard thickness sheet will not be caused, which avoids calibration errors, thus avoiding affecting the quality of the coating on site, and solving the problem of poor production quality. At the same time, it can also be calibrated in one step, without repeated calibration, and the calibration efficiency is high, which ensures the rapid development of metrology and calibration work and improves overall efficiency.
