Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchanger pipe orifice inspection tools, and relates to a inspection tool with a rapid pipe orifice inspection structure. Background Art

[0002] The main drawbacks of accurate three-dimensional inspection of pipe openings in existing heat exchanger water pipe structures include insufficient accuracy and low efficiency. These shortcomings arise from the fact that traditional inspection methods rely on contact measurement tools such as calipers and micrometers. These tools are prone to errors when measuring small dimensions, complex shapes, or confined spaces, and the operator's skill level significantly affects the results. Furthermore, comprehensive analysis of measurement data from multiple angles and positions is required for three-dimensional measurement, which is not only time-consuming but also prone to errors.

[0003] Conventional solutions include using higher-precision measuring tools. These tools are expensive and may not function properly in extreme environments. While automated inspection systems can improve efficiency and reduce human error, they are extremely expensive to develop and maintain, and may not be suitable for some heat exchanger pipes with special structures. While existing technologies have made some progress in accurately inspecting the three-dimensional dimensions of pipe orifices in heat exchanger pipe structures, many deficiencies remain. These deficiencies limit the accuracy and efficiency of inspections and increase production costs. Therefore, a new inspection tool capable of rapidly inspecting pipe orifice structures is urgently needed to address these issues. Summary of the Invention

The inner diameters of the internal detection cores inside the detection hole one and the detection hole two correspond to the inner diameters of the detection hole one and the detection hole two. By using the internal detection cores, it can be determined whether the inner diameters of the detection body one and the detection body two are accurate.

[0010] As a preferred embodiment, the back plate and the inspection column 1 and the inspection column 2 are separate structures. The lower end of the inspection column 2 is provided with a group of positioning seats for positioning with the internal card seat. The positioning seats and the upper end of the internal card seat are positioned and engaged with each other.

Several groups of heat exchange tube groups are provided on the rear side of the detection body 2, which can facilitate the entry of the detection body 1 and the detection body 2 by using the inner chamfers inside the detection hole 1 and the detection hole 2. At the same time, the precise fit is enhanced to ensure the precise docking of the detection body 1 and the detection hole 1 and the detection hole 2, thereby reducing resistance and improving the convenience of operation.

[0013] As a preferred embodiment, the heat exchange tube group, the inner holder, the detection body 1 and the detection body 2 are an integrated structure, and are all externally detected heat exchanger structures, and the outer positive corners of the back plate are all rounded.

[0014] After adopting the above technical scheme, the beneficial effects of the utility model are: by using the inspection column 1 and the inspection column 2 to measure the inner diameter of the tube mouth of the inspection body 1 and the inspection body 2, by using the internal detection core to determine whether the inner diameter size of the inspection body 1 and the inspection body 2 is accurate, by using the positioning seat and the internal clamping seat to determine the position of the back plate, the inspection column 1 and the inspection column 2, by using the internal chamfer inside the inspection hole 1 and the inspection hole 2 to facilitate the entry of the inspection body 1 and the inspection body 2, and at the same time strengthen the precise fit to ensure the accurate docking of the inspection body 1 and the inspection body 2 with the inspection hole 1 and the inspection hole 2, reduce resistance and improve the convenience of operation.
