Description

Technical Field

[0001] This utility model belongs to the field of metal pipe processing technology, specifically relating to a metal pipe marking tool and inspection fixture. Background Technology

[0002] In automotive thermal management systems, coolant piping plays a crucial role in heat transfer. To achieve lightweight design and corrosion resistance, aluminum alloy tubing (aluminum pipes) is widely used in coolant pipe manufacturing due to its superior performance. To ensure the stability and reliability of the piping system during vehicle operation, aluminum pipes typically require specialized clamps for secure installation at the target location. The clamps must be precisely engaged in the designated positions on the aluminum pipe to prevent damage caused by vibration, interference, or stress concentration. Therefore, clear and accurate markings must be pre-drilled on specific locations on the outer surface of the aluminum pipe, serving as the sole reference for subsequent clamp installation.

[0003] Traditional scribing methods rely heavily on manual operation (such as using a handheld scribing tool or marker to scribble lines at a defined location), resulting in low efficiency and poor consistency. To address this issue, specialized fixtures integrating scribing functions (such as fixtures with adjustable scribing or engraving tools) have been developed in the prior art. These designs combine scribing tooling and fixtures into one, avoiding the need to switch between separate tools and improving the uniformity of positioning references and operational efficiency. However, this design only guarantees accurate positioning during scribing; the scribing process still requires the operator to manually apply force to drive the engraving tool across the aluminum tube surface. This method still has significant drawbacks: the depth and clarity of the scribing are significantly affected by the operator's skill and force, easily leading to unclear markings or damage to the aluminum tube's surface coating / substrate; the operation still requires additional steps (applying force to scribble), limiting the efficiency improvement.

[0004] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0029] The shapes and sizes of the components in the attached drawings do not reflect the actual proportions of the product; they are only intended to illustrate the content of this utility model.

[0030] This utility model discloses a metal pipe scribing tool and inspection fixture. The metal pipe scribing tool includes a positioning base 1, on which a limiting component 3 for placing a metal pipe 2 is provided. A stamp assembly is movably connected to the limiting component 3, and a driving structure 4 is provided on the stamp assembly, which can drive the stamp assembly to move towards the metal pipe 2 to apply positioning marks. The stamp assembly includes a stamp plate 5, on which there is an oil inlet groove 6, and a stamp body 7 is slidably disposed in the oil inlet groove 6. The driving structure 4 is a driving rod with a pressing block 8 and a helical spring reset component 9. This utility model also provides a metal pipe inspection fixture containing this scribing tool. By using the technical solution of this utility model, damage to the pipe material can be avoided, the positioning marks 12 are clear and durable, have good positional consistency, and are convenient and efficient to operate, realizing the integration of inspection and scribing.

[0031] Example 1

[0032] This utility model provides a metal pipe inspection tool, such as Figure 1 As shown, the fixture includes a fixture body 10, which has multiple positioning units for fixing the metal tube 2. One of the positioning units includes a metal tube scribing tool. The fixture body 10 can inspect the size, shape, and other parameters of the metal tube 2. After passing the inspection, the scribing tool on it can be used to scribing, thus realizing the integration of inspection and scribing.

[0033] like Figures 2-4 As shown, the metal tube marking tool includes a positioning base 1, on which a limiting component 3 is provided for placing a metal tube 2. The limiting component 3 is a limiting groove formed on the top of the positioning base 1. The limiting groove is rectangular in shape and its width is not less than the diameter of the metal tube 2, so as to ensure that the metal tube 2 is completely placed in the limiting groove and to ensure the accuracy of positioning.

[0034] The limiting component 3 has a movable stamp assembly, which includes a stamp plate 5. The stamp plate 5 is hinged to the positioning base 1, so that when placing or removing the metal tube 2, the stamp plate 5 can be flipped upward around the hinge axis, making operation very convenient. The stamp plate 5 is provided with an ink supply groove 6 with an opening facing the positioning base 1. The stamp body 7 is slidably disposed in the ink supply groove 6. In this embodiment, the ink supply groove 6 integrates a sealed ink reservoir (ink chamber), which continuously supplies fast-drying metal-specific ink to the stamp body 7 through capillary permeation. In other embodiments, the ink supply groove 6 does not need to integrate a sealed ink reservoir. The stamp plate 5 can be flipped upward around the hinge axis to expose the stamp body 7, and ink can be manually added to the stamp body 7 to achieve ink supply to the stamp body 7.

[0035] The stamp body 7 is made of oil-resistant rubber. On the side facing the metal tube 2, it has an arc-shaped groove adapted to the metal tube 2. A 0.5mm wide closed-loop raised ring 11 is etched on the inner surface of the arc-shaped groove. The shape of this raised ring 11 can be designed according to actual marking requirements; for example, it can be a dot or a short line. When the stamp body 7 contacts the metal tube 2, the raised ring 11 leaves a corresponding positioning mark 12 on the surface of the metal tube 2 (e.g., ...). Figure 4 (As shown).

[0036] The stamp assembly has a driving structure 4 for driving the stamp assembly to move closer to the metal tube 2 to apply positioning marks 12 to the metal tube 2. In this embodiment, the driving structure 4 is a driving rod, one end of which is fixedly connected to the stamp body 7, and the other end extends outward through the oil supply groove 6, with the driving rod slidingly engaged with the oil supply groove 6. A cylindrical pressing block 8 is provided at the end of the driving rod away from the oil supply groove 6. The cross-sectional dimension of the pressing block 8 is larger than that of the driving rod, making it easier for the operator to press. A reset component 9 is provided on the driving rod. The reset component 9 is a helical spring sleeved on the driving rod, and the helical spring is arranged between the pressing block 8 and the outer wall of the oil supply groove 6. When the operator presses the pressing block 8, the driving rod drives the stamp body 7 to move closer to the metal tube 2, and the helical spring is compressed. When the pressing block 8 is released, under the elastic force of the helical spring, the driving rod drives the stamp body 7 to move away from the metal tube 2, achieving automatic reset.

[0037] The procedure for using this metal pipe inspection tool is as follows:

[0038] The formed metal tube 2 (aluminum tube) is placed on the inspection fixture body 10 to verify the conformity of its dimensions and three-dimensional orientation.

[0039] Flip the stamp plate 5 upwards and place the metal tube 2 to be marked into the limiting groove of the positioning base 1 to ensure that the position of the metal tube 2 is accurate.

[0040] Flip the stamp plate 5 downwards so that it covers the positioning base 1. At this time, the stamp body 7 is located directly above the metal tube 2.

[0041] The operator presses the pressing block 8, and the drive rod moves the stamp body 7 downward. The arc groove on the stamp body 7 fits against the outer surface of the metal tube 2. The raised ring line 11 in the arc groove coats the ink in the ink tank 6 onto the surface of the metal tube 2, forming a positioning mark 12.

[0042] Release the pressing block 8, and under the action of the spiral spring, the stamp body 7 automatically resets and moves upward away from the surface of the metal tube 2.

[0043] Flip the stamp plate 5 upwards and remove the metal tube 2 with the lines drawn, thus completing one line drawing operation.

[0044] This utility model also provides a metal pipe marking tool, which is the same as the metal pipe marking tool described in the above technical solution, and will not be described again here.

[0045] In summary, the metal pipe scribing tool and gauge provided by this utility model, through reasonable structural design, solves many problems existing in the metal pipe scribing technology. It has the advantages of convenient operation, high scribing efficiency, clear and accurate positioning marks, good consistency, less risk of damaging the pipe material, and durable markings. It is suitable for widespread application in the field of metal pipe processing.

[0046] It is understood that the above description is merely exemplary and the embodiments of this application do not limit the scope of the application.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the protection scope of the present utility model.
