For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0030] The utility model provides a kind of automobile oil pipe joint internal diameter detection device, for the internal diameter detection of vertical shaft hole 12 on the vertical shaft part 11 of oil pipe joint 1, as shown in Figure 1 The oil pipe joint 1 includes oil inlet hole on one end of horizontal shaft part and oil outlet hole on one end of vertical shaft part 11, since the oil outlet hole is located on the vertical shaft part 11, it is called vertical shaft hole 12 in this embodiment; of course, the internal diameter detection of similar structural components can also be applicable, which is not limited here.

[0031] As shown in Figures 2 to 10 The automobile oil pipe joint internal diameter detection device includes pneumatic internal diameter measuring instrument 2 and product carrier 3, specifically:

[0032] The pneumatic inner diameter measuring instrument 2 is a tool for precision dimensional measurement using pneumatic principles. Its main working principle is that when the measuring probe contacts the surface of the inner diameter being measured, the inner diameter of the product can be detected through signal conversion based on the different gaps, and then the specific dimensional data is displayed on the display device. In this embodiment, the pneumatic inner diameter measuring instrument includes an inner diameter detection head 21 and a display device 22. Figure 4 As shown, the inner diameter detection head 21 has an air outlet 211 on its side wall, and the outer diameter of the inner diameter detection head 21 is adapted to the inner diameter of the vertical shaft hole 12, so that the inner diameter detection head 21 can be inserted into the vertical shaft hole 12; the display device 22 can display the inner diameter value of the vertical shaft hole 12.

[0033] like Figure 5 As shown, the product carrier 3 is provided with a first through hole 31 and a second through hole 32 arranged vertically and coaxially. The inner diameter of the first through hole 31 is adapted to the outer diameter of the vertical shaft portion 11, allowing the vertical shaft portion 11 to be inserted into the first through hole 31. The inner diameter of the second through hole 32 is adapted to the outer diameter of the inner diameter detection head 21, allowing the inner diameter detection head 21 to be inserted into the second through hole 32. Furthermore, since the inner diameter of the first through hole 31 is larger than the inner diameter of the second through hole 32, a boss 33 is formed at the junction of the first through hole 31 and the second through hole 32. The boss 33 can be used to support the bottom of the vertical shaft portion 11. During inspection, if... Figure 6 As shown, the inner diameter detection head 21 passes through the second through hole 32, so that the product carrier 3 is sleeved on the inner diameter detection head 21, and the height between the top end face of the inner diameter detection head 21 and the boss 33 is less than the depth of the vertical shaft hole 12, so that the top end face of the inner diameter detection head 21 does not contact the top of the vertical shaft hole 12.

[0034] The automotive oil pipe joint inner diameter detection device with the above structure, through the cooperation of the pneumatic inner diameter measuring instrument 2 and the product carrier 3, can not only realize the automatic detection of the inner diameter of the vertical shaft hole 12 on the vertical shaft part 11 of the oil pipe joint 1, greatly improving the detection efficiency and quality, but also, since the top end face of the inner diameter detection head 21 does not contact the top of the vertical shaft hole 12 during detection, it can also prevent the vertical shaft hole 12 of the oil pipe joint 1 from being scratched or abraded by the inner diameter detection head 21, thereby improving the product qualification rate and reducing production costs.

[0035] In some embodiments, the inner diameter detection head 21 is movably connected to the product carrier 3, thereby facilitating the replacement, cleaning, or maintenance of the product carrier 3.

[0036] In some embodiments, the automotive oil pipe joint inner diameter detection device further includes a leak-proof detection mechanism 4, specifically, as shown in the following example.Figure 7 As shown, the leak detection mechanism 4 includes a product sensor 41 and a lifting assembly 42; wherein, the product sensor 41 can be used to detect whether the oil pipe connector 1 is placed in the product carrier 3, and the product sensor 41 can be a photoelectric sensor, pressure sensor, etc., which is not limited here; the lifting assembly 42 can drive the product carrier 3 to move up and down.

[0037] The automotive oil pipe joint inner diameter detection device with the above structure, when... Figure 7 When the oil pipe connector 1 is not placed in the product carrier 3 as shown, the lifting assembly 42 drives the product carrier 3 to move upward to the unloading position to accommodate the oil pipe connector 1; when... Figure 8 As shown, after the product sensor 41 detects that the oil pipe connector 1 has been placed in the product carrier 3, as indicated... Figure 9 The lifting assembly 42 shown drives the product carrier 3 to move downward to the inspection station. At this time, the inner diameter detection head 21 is inserted into the vertical shaft hole 12 to detect the inner diameter. After the inspection is completed, the lifting assembly 42 drives the product carrier 3 to move upward to the unloading station. At this time, the oil pipe joint 1 that has been inspected is removed and the oil pipe joint 1 to be inspected is put in. Then, the lifting assembly 42 drives the product carrier 3 to move downward to the inspection station to carry out the inspection. This cycle is repeated.

[0038] Through the cooperation of the product sensor 41 and the lifting assembly 42, the product carrier 3 and the oil pipe connector 1 are lowered to the inspection station during each inspection. After the inspection is completed, they are raised to the unloading station. During the inspection, the worker can judge whether the inspection has been completed based on the position changes of the product carrier 3 and the oil pipe connector 1. This avoids the problem of missing inspections caused by taking away the product directly before the inspection is completed after it is lowered, which can further improve the inspection quality.

[0039] In some embodiments, the product sensor 41 is a laser sensor disposed on the side of the product carrier 3; the laser sensor adopts a non-contact measurement method, is suitable for long-distance detection, and has the advantages of high measurement accuracy and good reliability.

[0040] In some embodiments, such as Figure 8 , Figure 9 , Figure 10 As shown, the lifting assembly 42 includes a lifting plate 421 and a lifting cylinder 422; the lifting plate 421 is fixed to the bottom of the product carrier 3, and the lifting plate 421 is provided with a third through hole 423 that allows the inner diameter detection head 21 to pass through; the lifting cylinder 422 can drive the lifting plate 421 to move up and down, thereby driving the product carrier 3 fixed on the lifting plate 421 to move up and down.

[0041] The automotive oil pipe joint inner diameter detection device with the above structure, through the cooperation of the lifting plate 421 and the lifting cylinder 422, can not only realize the up and down movement of the product carrier 3, but also make the lifting process more stable and reliable because the lifting plate 421 is fixed to the bottom of the product carrier 3.

[0042] In some embodiments, the top of the inner diameter detection head 21 is made of tungsten steel, and as... Figure 4 As shown, the top of the inner diameter detection head 21 has a rounded chamfer structure.

[0043] The automotive oil pipe joint inner diameter detection device with the above structure uses tungsten steel material, which makes the top of the inner diameter detection head 21 harder and more wear-resistant, resulting in high cost performance and long service life. Furthermore, setting the top of the inner diameter detection head 21 to a rounded chamfer structure can reduce friction during insertion, avoid damage to the product hole wall, and extend the service life of the detection head.

[0044] In some embodiments, at least two air outlets 211 are evenly arranged circumferentially on the side wall of the inner diameter detection head 21; in this embodiment, the number of air outlets 211 is two, arranged symmetrically on the left and right, but of course, there can also be three, four, etc.

[0045] The automotive oil pipe joint inner diameter detection device with the above structure has two or more air outlets 211 that can help balance the airflow, improve the stability of the measurement, and enhance the measurement accuracy.

[0046] In some embodiments, such as Figure 5 As shown, the product carrier 3 is annular. Setting the product carrier 3 in an annular shape prevents the outer edge of the product carrier 3 from scratching the oil pipe connector 1 during operation, thus preventing an increase in the product defect rate and improving the reliability of the automotive oil pipe connector inner diameter detection device.

[0047] In some embodiments, the automotive oil pipe joint inner diameter detection device further includes a large-diameter alarm 5 and a small-diameter alarm 6; when the inner diameter value of the vertical shaft hole 12 detected on the display device 22 is greater than a set value, the large-diameter alarm 5 lights up and alarms, and when the inner diameter value of the vertical shaft hole 12 detected on the display device 22 is less than a set value, the small-diameter alarm 6 lights up and alarms.

[0048] The automotive oil pipe joint inner diameter detection device with the above structure can directly judge the detection results through the large-diameter alarm 5 and the small-diameter alarm 6, which can make the detection results clearer and more obvious, and further improve the detection efficiency.

[0049] In some embodiments, the automobile oil pipe joint inner diameter detection device further comprises a detection table 7, the pneumatic inner diameter measuring instrument 2, the product carrier 3, the leak detection mechanism 4, the large-diameter alarm 5 and the small-diameter alarm 6 are arranged on the detection table 7, and the detection table 7 can also be used to place the oil pipe joint 1 to be detected or the oil pipe joint 1 that has been detected.

[0050] The automobile oil pipe joint inner diameter detection device with the above structure can improve the operation convenience of detection, thereby further improving the detection efficiency.

[0051] The above embodiments are only preferred embodiments of the present application, and do not limit the scope of the present application. Any equivalent changes made according to the shape, structure and principle of the present application should be covered within the protection scope of the present application.
