Abstract
Description
Technical Field
[0001] The utility model relates to the field of mechanical assembly, in particular to a pipe assembly shrinkage size inspection tool. Background Art
[0002] Pipe assemblies are widely used in mechanical structures. They not only transport fluids but also often serve as structural supports. In pipe assembly, shrinking is a common processing technique. This involves reducing the diameter of one or both ends of the pipe to allow for a tight connection with other pipes or fittings of different diameters. Narrowed pipe joints provide excellent sealing properties, effectively preventing liquid or gas leakage. Furthermore, shrinking connections do not require complex tools or equipment, making them easier to quickly install on-site. Consequently, they are widely used in many industries, such as automotive, aerospace, and refrigeration and air conditioning.
[0003] For example, in the refrigeration and air conditioning industry, the connection of evaporators, condensers, compressors, expansion valves, and other components requires constriction technology to connect pipe assemblies of varying diameters, ensuring efficient refrigerant circulation. With the rapid growth of the refrigeration and air conditioning industry, the number of air conditioner models has increased, and the internal piping has become increasingly complex. Therefore, the connection and assembly of pipe assemblies of varying diameters has become increasingly important. The dimensional accuracy of the pipe assembly constriction is particularly important, especially the length of the constriction, which directly affects the quality of the connection between pipe assemblies.
[0004] In the current production of air-conditioning pipe assemblies, the length inspection of the pipe assembly shrinkage mainly relies on manual measurement using a vernier caliper and then comparing it with the dimensions in the design drawings to determine whether the shrinkage size is qualified. This inspection method is not only inefficient and affects production efficiency, but is also prone to measurement errors, which affects the quality control of the pipe assembly shrinkage and, in turn, affects the production quality of the air conditioner. Utility Model Content
[0005] The utility model provides a pipe assembly shrinkage size inspection tool, which can simply, quickly and accurately inspect whether the pipe assembly shrinkage length is qualified. The specific technical solution is as follows:
[0006] A pipe assembly necking size inspection tool is used for inspecting the necking length of a pipe assembly, with the minimum necking length set to A and the maximum length set to B. The tool comprises a base, wherein the base includes a first inspection block and a second inspection block distributed left and right and with the bottoms located on the same horizontal plane. The height of the first inspection block is A, and the height of the second inspection block is B. An inspection hole is provided at the junction of the first inspection block and the second inspection block, and the inner diameter of the inspection hole is adapted to the necking diameter of the pipe assembly.
[0007] Furthermore, the height of the base is adjustable.
[0008] Furthermore, the first inspection block and the second inspection block are detachably connected.
[0009] Furthermore, the inner diameter of the inspection hole is adjustable.
[0010] Furthermore, at least two inspection holes with different inner diameters are provided at the junction of the first inspection block and the second inspection block.
[0011] Furthermore, the inspection hole is a circular through hole.
[0012] Furthermore, the inner diameter of the inspection hole is between 4.5 mm and 6.5 mm.
[0013] Furthermore, the inspection hole is located at the center of the base.
[0014] Furthermore, the base is in a ring shape.
[0015] Furthermore, the base is made of stainless steel.
[0016] The utility model provides a pipe assembly shrinkage size inspection tool, which sets a first inspection block and a second inspection block with the same height according to the minimum and maximum lengths of the pipe assembly shrinkage, and sets an inspection hole adapted to the shrinkage diameter of the pipe assembly at the junction of the first inspection block and the second inspection block, and then inserts the shrinkage of the pipe assembly into the inspection hole. By observing the position of the top end of the shrinkage of the pipe assembly in the inspection hole from above the pipe assembly shrinkage size inspection tool, it is possible to simply, quickly and accurately inspect whether the shrinkage length of the pipe assembly is qualified, which not only improves the inspection efficiency, but also reduces the measurement error caused by manual length measurement, and is more conducive to the quality control of the shrinkage of the pipe assembly, thereby improving the production quality of the air conditioner.
[0017] Furthermore, by arranging the base of the pipe assembly shrinkage size inspection tool to be height-adjustable, it can adapt to the length inspection of the shrinkage of pipe assemblies of more different lengths, thereby improving the versatility of the pipe assembly shrinkage size inspection tool.
[0018] Furthermore, by arranging the first inspection block and the second inspection block of the pipe assembly shrinkage size inspection tool to be detachably connected, the first inspection block and the second inspection block of the corresponding specifications can be selected according to the minimum length and maximum length of the pipe assembly shrinkage, and then assembled for inspection. The selection is more flexible, which can further improve the versatility of the pipe assembly shrinkage size inspection tool.
[0019] Furthermore, by setting the inspection hole of the pipe assembly shrinkage size inspection tool to have an adjustable inner diameter, it can be suitable for the length inspection of the shrinkage of pipe assemblies with more different diameters, which can further improve the versatility of the pipe assembly shrinkage size inspection tool.

[0029] The utility model provides a pipe assembly shrinkage size inspection tool, which can be used for the length inspection of the shrinkage 11 of the pipe assembly 1, such as Figure 1 As shown, the pipe assembly 1 includes a necking 11 and a pipe body 12. In this embodiment, the size requirements of the necking 11 of the pipe assembly 1 during production are set as follows: the minimum length is A, the maximum length is B, the length tolerance is BA, and the diameter is D; Figure 2 、 Figure 3 、 Figure 4As shown, the pipe assembly shrinkage size inspection tool includes a base 2, and the base 2 includes a first inspection block 21 and a second inspection block 22 distributed on the left and right, and the bottoms of the first inspection block 21 and the second inspection block 22 are located in the same horizontal plane; the first inspection block 21 and the second inspection block 22 can be an integrated structure as shown in this embodiment, or can be detachably connected, which is not limited here; wherein, the height of the first inspection block 21 is A (i.e., equal to the minimum length of the shrinkage 11 of the pipe assembly 1), the height of the second inspection block 22 is B (i.e., equal to the maximum length of the shrinkage 11 of the pipe assembly 1), and a step is provided at the junction of the first inspection block 21 and the second inspection block 22. The height of the step is the height difference BA between the first inspection block 21 and the second inspection block 22 (that is, equal to the length tolerance value of the necking 11 of the pipe assembly 1); an inspection hole 3 is provided at the junction of the first inspection block 21 and the second inspection block 22, and the inner diameter of the inspection hole 3 is adapted to the diameter of the necking 11 of the pipe assembly 1, allowing the necking 11 of the pipe assembly 1 to pass through, but not allowing the pipe body 12 of the pipe assembly 1 to pass through; the inspection hole 3 can be a circular through hole as in the present embodiment. Of course, it can also be a triangle, square, regular pentagon, regular hexagon, etc., the inner diameter of which is adapted to the diameter of the necking 11 of the pipe assembly 1 and allowing the necking 11 of the pipe assembly 1 to pass through. There is no restriction here.
[0030] like Figure 5 、 Figure 6 、 Figure 7 The figure shows the use state of the pipe assembly shrinkage size inspection tool. When in use, first insert the shrinkage 11 of the pipe assembly 1 from bottom to top into the inspection hole 3 until it can no longer be inserted. At this time, the position of the top end of the shrinkage 11 of the pipe assembly 1 in the inspection hole 3 is observed from above the pipe assembly shrinkage size inspection tool: (1) If Figure 6 、 Figure 7As shown in , the top of the constriction 11 of the tube assembly 1 is located between the top surfaces of the first inspection block 21 and the second inspection block 22, that is, located on the step at the junction of the first inspection block 21 and the second inspection block 22, which means that the actual length C of the constriction 11 of the tube assembly 1 is within the allowable error range and is a qualified product; (2) if the top of the constriction 11 of the tube assembly 1 is lower than the top surface of the first inspection block 21 (that is, it is not exposed from the inspection hole 3), it means that the length of the constriction 11 of the tube assembly 1 is less than the minimum length A, and is an unqualified product; (3) if the top of the constriction 11 of the tube assembly 1 is higher than the top surface of the second inspection block 22 (that is, it is completely exposed from the inspection hole 3), it means that the length of the constriction 11 of the tube assembly 1 is greater than the maximum length B, and is also an unqualified product. In addition, the pipe assembly necking size inspection tool can also inspect the diameter of the necking 11 of the pipe assembly 1. Specifically, if the necking 11 of the pipe assembly 1 cannot be inserted into the inspection hole 3, it means that the diameter of the necking 11 of the pipe assembly 1 is greater than the set value D, or if the necking 11 of the pipe assembly 1 can swing left and right after being inserted into the inspection hole 3, it means that the diameter of the necking 11 of the pipe assembly 1 is less than the set value D, and both are unqualified products.
[0031] The pipe assembly necking size inspection tooling with the above structure is adopted, and a first inspection block 21 and a second inspection block 22 with the same height are respectively set according to the minimum length and the maximum length of the necking 11 of the pipe assembly 1, and an inspection hole 3 adapted to the diameter of the necking 11 of the pipe assembly 1 is set at the junction of the first inspection block 21 and the second inspection block 22. Then, the necking 11 of the pipe assembly 1 is inserted into the inspection hole 3. By observing the position of the top end of the necking 11 of the pipe assembly 1 in the inspection hole 3 above the pipe assembly necking size inspection tooling, it is possible to simply, quickly and accurately inspect whether the length of the necking 11 of the pipe assembly 1 is qualified. This not only improves the inspection efficiency, but also reduces the measurement error caused by manual length measurement, which is more conducive to the quality control of the necking 11 of the pipe assembly 1, thereby improving the production quality of the air conditioner.
[0032] In some embodiments, the base 2 can be set to be height-adjustable. Specifically, this can be achieved by setting a height adjustment component inside the base 2 to adjust the distance between the bottom surface and the top surface of the base 2, etc., which is not limited here.
[0033] The pipe assembly shrinkage size inspection tool with the above structure can adapt to the length inspection of the shrinkage 11 of pipe assemblies 1 of more different lengths by setting the base 2 to be height-adjustable, thereby improving the versatility of the pipe assembly shrinkage size inspection tool.
[0034] In some embodiments, the first inspection block 21 and the second inspection block 22 are detachably connected, for example, by common connection methods such as snap connection, slide rail connection, and screw connection.
[0035] The pipe assembly shrinkage size inspection tool using the above structure, by setting the first inspection block 21 and the second inspection block 22 to be detachably connected, can select the first inspection block 21 and the second inspection block 22 of the corresponding specifications according to the minimum length and maximum length of the shrinkage 11 of the pipe assembly 1, and assemble them for inspection. The selection is more flexible, which can further improve the versatility of the pipe assembly shrinkage size inspection tool.
[0036] In some embodiments, the inner diameter of the inspection hole 3 is adjustable, so that it can be suitable for length inspection of the constriction 11 of pipe assemblies 1 with more different diameters, which can further improve the versatility of the pipe assembly constriction size inspection tool.
[0037] In some embodiments, at least two inspection holes 3 with different inner diameters are provided at the junction of the first inspection block 21 and the second inspection block 22, such as two, three, four, five, etc., so that the length inspection of the shrinkage 11 of pipe assemblies 1 with more different diameters can be directly applied without adjusting the pipe assembly shrinkage size inspection tooling, thereby improving the versatility of the pipe assembly shrinkage size inspection tooling and making the operation more convenient and quick.
[0038] In some embodiments, the inspection hole 3 is a circular through hole whose inner diameter is adapted to the diameter of the constriction 11 of the tube assembly 1 , which can improve the fit between the outer wall of the constriction 11 of the tube assembly 1 and the inspection hole 3 during inspection, thereby improving the reliability of the tube assembly constriction size inspection tooling.
[0039] In some embodiments, the inner diameter of the inspection hole 3 is between 4.5 mm and 6.5 mm, which is the diameter range of the constriction 11 of the tube assembly 1 commonly used in the industry, and has better versatility and practicality.
[0040] In some embodiments, the inspection hole 3 is located at the center of the base 2, which can be more convenient for processing and manufacturing and is more in line with usage habits.
[0041] In some embodiments, the base 2 is in a circular shape. The circular shape has no sharp edges and is safer. It can not only prevent people from being scratched, but also prevent the tube assembly 1 from being scratched. In addition, the circular shape is more convenient to carry and use.
[0042] In some embodiments, the base 2 is made of stainless steel, which has a high hardness and can prevent damage to the inner wall of the inspection hole 3 during long-term use. It is also more durable and can increase the service life of the pipe assembly shrinkage size inspection tooling.
[0043] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Any equivalent changes based on the shape, structure and principle of the present invention should be included in the scope of protection of the present invention.
