[0002] The cylinder head gasket of an automobile engine is an important sealing element between the engine block and the cylinder head. Its main function is to prevent the leakage of engine coolant and lubricating oil, as well as to prevent the escape of combustion gases. The quality of the cylinder head gasket directly affects the engine's performance, reliability, and service life. In the production process of the cylinder head gasket, the machining accuracy and quality of the small holes are one of the key factors. These small holes are used to ensure that the coolant and lubricating oil inside the engine can flow normally, while preventing gas leakage. Therefore, the inspection of the small holes of the cylinder head gasket is crucial.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0042] Please see Figure 1-4 One embodiment of this utility model is: a batch small hole detection device for automotive engine cylinder head gaskets, including a conveyor belt 1 and a cylinder head gasket 2, the cylinder head gasket 2 being disposed above the conveyor belt 1 for moving and detecting the cylinder head gasket 2, and further including:
[0043] Multiple fixing mechanisms 3 are sequentially arranged on the conveyor belt 1 for installing the sealing cylinder gasket 2;
[0044] The testing mechanism 4 is located below the conveyor belt 1 and is used to test the sealing cylinder gasket 2;
[0045] Box 5 is positioned above the testing mechanism 4;
[0046] Camera 6 is installed on the outer wall of housing 5 and is used to take pictures of the test results;
[0047] Among them, testing agency 4 includes:
[0048] U-shaped frame 41 is located below conveyor belt 1;
[0049] Lamp 48 is located on one side of U-shaped bracket 41, and the light beam is directed toward the sealing cylinder head gasket 2;
[0050] Imaging plate 47, located on the other side of U-shaped frame 41, is used to receive the imaging spot of the small hole on the sealing cylinder gasket 2.
[0051] Testing agency 4 also includes:
[0052] Two slide rods 42 are fixedly connected to the inner wall of the U-shaped frame 41, and two sliders 43 are slidably connected to the outer walls of the two slide rods 42 respectively, and are located on the front and rear sides of the conveyor belt 1.
[0053] Electric actuator 2 45 is fixedly connected above the front slider 43. The output end of electric actuator 2 45 is fixedly connected to a loop-shaped mounting bracket 46. The top of the rear slider 43 is connected to another loop-shaped mounting bracket 46 through a connecting post.
[0054] Furthermore, the lamp 48 and the imaging plate 47 are respectively mounted on two U-shaped mounting brackets 46.
[0055] Electric push rods 44 are fixedly connected to the front and rear sides of the inner wall of the U-shaped frame 41, and the output end of the electric push rods 44 is connected to the slider 43 for moving the slider 43.
[0056] Working principle: During the production of cylinder head gasket 2, it is necessary to inspect the openings on cylinder head gasket 2. The small holes on the cylinder head gasket are crucial for the normal operation of the engine and are very small.
[0057] At this point, by placing the sealing cylinder gasket 2 on the fixing mechanism 3 and changing the position of the sealing cylinder gasket 2 by moving the conveyor belt 1, and aligning it with the detection mechanism 4, the operation is stopped and detection is performed. At the same time, by turning on the lamp 48, the sealing cylinder gasket 2 is illuminated inside the housing 5. According to the pinhole imaging principle, the light passes through the rectangular through hole and enters the pinhole on the sealing cylinder gasket 2, appearing on the imaging plate 47. At this time, by continuously controlling the two electric push rods 44 to adjust forward and backward, and by adjusting the position of the lamp up and down through the electric push rod 45, the imaging position can be changed, and the image is captured by the camera 6. The detection results are then comprehensively analyzed by the computer, thereby improving the detection efficiency.
[0058] Please see Figure 1-4 Based on the above embodiments, in another embodiment of the present invention, the fixing mechanism 3 includes:
[0059] Multiple fixing rods 31 are fixedly connected to the conveyor belt 1;
[0060] Insert plate 32 is inserted into the outer wall of fixing rod 31 for connecting insert plate 32;
[0061] The bottom of the placement frame 34 is connected to the top of the insert plate 32 via two connecting rods 33, and the sealing cylinder gasket 2 is placed inside the placement frame 34.
[0062] The fixed mechanism 3 also includes:
[0063] The round rod 35 is fixedly connected to the rectangular hole opened on the front of the placement frame 34, and the outer wall of the round rod 35 is provided with a threaded groove.
[0064] Multiple baffles 36 are threaded onto the outer wall of the round rod 35 to cover the large hole at the piston in the sealing cylinder gasket 2.
[0065] A push block 37 is movably connected to the middle of the placement frame 34, and the top of the push block 37 contacts the bottom of the sealing cylinder gasket 2;
[0066] Two push rods 38 are fixedly connected to the bottom sides of the push block 37 respectively, and are movably inserted into the circular slots opened on the insert plate 32;
[0067] A spring 39 is installed inside the circular groove to push the push block 37 upward;
[0068] An arc-shaped contact plate 7 is fixedly connected to the back of the housing 5, and the outer wall of the arc-shaped contact plate 7 contacts the top of the sealing cylinder gasket 2 to resist the downward movement of the sealing cylinder gasket 2.
[0069] The bristles 8 are installed on the back of the housing 5 and located at the rectangular through hole opened on the back of the housing 5, and the bristles 8 abut against the outer wall of the placement frame 34.
[0070] Working principle: When the test is performed, the plate 36 is rotated to adjust the diameter of the piston hole on the sealing cylinder gasket 2. Then, the sealing cylinder gasket 2 to be tested is directly inserted into the slot of the placement frame 34, and the piston hole is blocked by the baffle 36 to avoid affecting the imaging. At this time, the insertion plate 32 is directly inserted into the fixing rod 31 for quick fixation. When the conveyor belt 1 moves, it will drive the fixing mechanism 3 to move. At this time, the placement frame 34 will come into contact with the brush 8, and the brush 8 will brush the sealing cylinder gasket 2 in the placement frame 34 to remove the material that has not been separated during drilling, so as to improve the detection effect. At the same time, the arc-shaped contact plate 7 touches the sealing cylinder gasket 2, which will push the sealing cylinder gasket 2 down to perform the test. When the movement stops, the brush 8 and the arc-shaped contact plate 7 can prevent the light from being scattered and increase the irradiation intensity of the light entering the small hole, so as to make the imaging effect clearer.
[0071] After the inspection is completed, the conveyor belt 1 moves, at which point the arc-shaped contact plate 7 releases its pressure on the sealing gasket 2. Under the action of the spring 39, it pushes the push rod 38 upward, thereby pushing the sealing gasket 2 upward, so that the inspected sealing gasket 2 can be removed more easily, thus improving work efficiency.
[0072] This utility model provides a batch small hole detection device for automotive engine cylinder head gaskets. There are many methods and approaches to implement this technical solution; the above description is only a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
