[0002] EGR (Exhaust Gas Recirculation) is a mechatronic device installed on diesel engines to control the amount of exhaust gas recirculated back into the intake system. It is typically located on the right side of the intake manifold, near the throttle body, and is connected to a short metal tube that leads to the exhaust manifold. Its function is to control the amount of exhaust gas entering the intake manifold, ensuring a certain amount of exhaust gas is recirculated there.

[0003] The EGR cooler is a very important and key component in the exhaust gas recirculation device. It is used to cool the exhaust gas to reduce the temperature and pressure of the mixture and improve the efficiency of the EGR system.

[0004] After the EGR cooler is produced, the connection holes and installation holes of the connected and assembled pipes need to be inspected. The existing method is generally manual inspection, which is not only inefficient but also has poor inspection accuracy and cannot meet production needs. Utility Model Content

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0024] The utility model provides an EGR cooler hole position detection mechanism, such as Figure 1-3 Shown, including:

[0025] The base 1 has a handle 6 detachably mounted at each of its four corners;

[0026] The mold base 2 is adapted to the cooler and is used to support and place the cooler;

[0027] There are three brackets 3, each of which has a positioning pin 4 on its top. The three positioning pins 4 correspond to the three support holes of the cooler.

[0028] There are multiple columns 7, each of which has a hole position detection mechanism 8 detachably mounted thereon. The detection ends of the hole position detection mechanism 8 are arranged in one-to-one correspondence with the hole positions of the cooler.

[0029] The installation positions of the mold base 2, the bracket 3, and the hole position detection mechanism 8 on the base 1 are calculated based on qualified cooler products.

[0030] The cooler is supported by the mold base 2, and then the cooler is installed in position through the bracket 3 and the positioning pin 4. If the three supports of the cooler cannot be installed on the corresponding positioning pin 4, it is unqualified, otherwise it is qualified;

[0031] In addition, the hole position detection mechanism 8 set on the column 7 is used to squeeze and position each pipe hole of the cooler. If the detection end of the hole position detection mechanism 8 is inserted into the pipe hole, the cooler is qualified, otherwise it is unqualified. The automatic detection of the cooler pipe holes is realized, which not only greatly improves the detection efficiency, but also ensures the accuracy of the detection.

[0032] The hole position detection mechanism 8 includes a slide cylinder 81, a linear bearing 82, a spring 83, a probe 84, a guide rod 85, and a photoelectric sensor 86, wherein the slide cylinder 81 is detachably mounted on the top of the column 7, the linear bearing 82 is connected to the free end of the slide cylinder 81, the front end of the linear bearing 82 is sleeved with a spring 83, the probe 84 is connected to the linear bearing 82 of the spring 83, the guide rod 85 is connected to the rear end of the linear bearing 82, and the photoelectric sensor 86 is detachably mounted on the rear end top surface of the slide cylinder 81, the guide rod 85 and the photoelectric sensor 86 are arranged correspondingly front and back, and the guide rod 85 is located above the photoelectric sensor 86.

[0033] During the inspection, 81 drives 82 to move forward, so that 84 is inserted into or contacts the pipe opening. If 84 is inserted into the pipe hole, it is qualified. If 84 is not inserted into the pipe hole, the forward pressure cooperates with the cooler compression spring to make 82 move backward and drive 85 to move in the direction of 86, so that 85 covers 86. At this time, 86 generates a signal to indicate that the hole position is unqualified, realizing automatic inspection.

[0034] It also includes a rotary pressing cylinder 5 for cooperating with the mold base 2 and the positioning pin 4 to press and fix the cooler.

[0035] It also includes a barcode scanner 9, which is installed at a height corresponding to the cooler and is used to read the product information of the current cooler and bind the test data. The operator can obtain the test data by scanning the code and then know whether the product is qualified.

[0036] Cooler 10, such as Figure 4 As shown, three supports 101 are provided, and support holes are opened on the supports 101 for installation on the car, and the cooler 9 is provided with multiple pipes, and flanges are provided at both ends of the cooler 10 for connecting to the EGR valve.
