Description

Technical Field

[0001] This utility model relates to the technical field of sealing test devices, and in particular to an engine cylinder head gasket sealing test device. Background Technology

[0002] A cylinder head gasket, also known as a cylinder liner, is located between the cylinder head and the cylinder block. Its function is to fill the microscopic gaps between the cylinder block and the cylinder head, ensuring good sealing at the mating surfaces, thereby ensuring the sealing of the combustion chamber and preventing cylinder oil leakage.

[0003] In the prior art, cylinder head gaskets are often directly installed in the application product after production, and then their sealing performance is tested. After the test, excess oil overflows around the cylinder head gasket and cannot be cleaned or recycled. Moreover, the oil used during the test cannot be collected in a centralized manner, which is not convenient for secondary recycling. Therefore, we propose an engine cylinder head gasket sealing performance testing device. Utility Model Content

Four sets of recovery pipes 4 are fixedly connected to the inner side of the collection box 3. Each of the four sets of recovery pipes 4 has a recovery hole on its outer side. A first pressure plate 5 is fixedly connected to the outer side of the four sets of recovery pipes 4 near the upper end. A sealing gasket body 6 is installed on the upper end of the first pressure plate 5. A second mounting plate 7 is fixedly connected to the rear end of the workbench 1.

An oil delivery hose 12 is fixedly connected to the outlet of the first oil pump 10.

[0022] In this embodiment, the cleaning mechanism 2 includes four sets of support rods 21 fixedly connected to the workbench 1. The upper ends of the four sets of support rods 21 are all fixedly connected to an external gear ring 22. The upper end of the external gear ring 22 is fixedly connected to a limit ring 23. The inner and outer sides of the limit ring 23 are slidably connected to two sets of symmetrical rollers 24. The two sets of rollers 24 are rotatably connected to a first mounting plate 25 through a rotating shaft. A motor 26 is mounted on the upper end of the first mounting plate 25. A gear 27 is rotatably connected to the lower end of the first mounting plate 25 through a rotating shaft. The output shaft of the motor 26 is fixedly connected to the gear 27. The outer side of the gear 27 meshes with the external gear ring 22.

[0023] Specifically, the motor 26 is started, which drives the gear 27 to rotate. The gear 27 meshes with the external gear ring 22, thereby driving the first mounting plate 25 to rotate. The scraped oil drops fall into the collection box 3 for recycling. The support rod 21 provides support for the external gear ring 22 and helps stabilize its position.

[0024] In this embodiment, a limiting block 28 is fixedly connected to the lower end of the first mounting plate 25, and the inner side of the limiting block 28 is slidably connected to the limiting ring 23.

[0025] Specifically, the roller 24 slides on both the inner and outer sides of the limiting ring 23 to reduce the friction generated when the first mounting plate 25 moves, and the limiting block 28 slides on the outer side of the limiting ring 23 to prevent misalignment when the first mounting plate 25 moves.

[0026] In this embodiment, a first electric telescopic rod 29 is installed at the front end of the first mounting plate 25, and a scraper 210 is fixedly connected to the output shaft of the first electric telescopic rod 29.

[0027] Specifically, when the first mounting plate 25 moves in a circular motion, it drives the first electric telescopic rod 29 to move. The first electric telescopic rod 29 retracts according to the length of the sealing gasket body 6. The first electric telescopic rod 29 scrapes off the oil overflowing around the sealing gasket body 6 through the scraper 210 to avoid affecting the next set of sealing gasket body 6 tests.

[0028] In this embodiment, two sets of symmetrical second electric telescopic rods 11 are installed on the inner side of the cleaning mechanism 2. The output shafts of the two sets of second electric telescopic rods 11 are fixedly connected to a diversion box 13. The upper end of the diversion box 13 is fixedly connected to the oil delivery hose 12. The lower end of the diversion box 13 is fixedly connected to four sets of output pipes 14. The outer sides of the four sets of output pipes 14 are fixedly connected to a second pressure plate 15 near the lower end.

[0029] Specifically, starting the second electric telescopic rod 11 causes the diversion box 13 to move downward, the diversion box 13 causes the output pipe 14 to move downward, and the output pipe 14 causes the second pressure plate 15 to press the sealing gasket body 6 tightly.

[0030] In this embodiment, a second oil pump 16 is installed on the upper end of the workbench 1 near one side. The input port of the second oil pump 16 is fixedly connected to the collection box 3, and the output port of the second oil pump 16 is fixedly connected to the return pipe 17. The other end of the return pipe 17 is fixedly connected to the oil tank 9.

[0031] Specifically, the second oil pump 16 is started to output the oil in the collection tank 3 through the return pipe 17 to the oil tank 9 for circulation, thereby testing the sealing performance of the sealing gasket body 6.

[0032] Working principle: When using this equipment, place the sealing gasket body 6 on the upper end of the first pressure plate 5 and align it. Start the second electric telescopic rod 11 to drive the diversion box 13 to move downward. The diversion box 13 drives the output pipe 14 to move downward. The output pipe 14 drives the second pressure plate 15 to press the sealing gasket body 6. Start the first oil pump 10 installed at the lower end of the mounting bracket 8. The first oil pump 10 outputs the oil in the oil tank 9 to the diversion box 13 through the oil delivery hose 12. Then the diversion box 13 diverts the oil through the output pipe 14. The oil in the output pipe 14 passes through the sealing gasket body 6 and enters the recovery pipe 4. Then it flows into the collection box 3 through the recovery hole on the outside of the recovery pipe 4. Start the second oil pump 16 to output the oil in the collection box 3 to the oil tank 9 through the return pipe 17 for circulation, thereby testing the sealing performance of the sealing gasket body 6.

[0033] When oil overflows between the second pressure plate 15 and the first pressure plate 5, it indicates that the sealing performance of the sealing gasket body 6 is unqualified. The motor 26 is started, and the motor 26 drives the gear 27 to rotate. The gear 27 meshes with the external gear ring 22, thereby driving the first mounting plate 25 to rotate. The roller 24 slides on the inner and outer sides of the limiting ring 23 to reduce the friction generated when the first mounting plate 25 moves. The limiting block 28 slides on the outside of the limiting ring 23 to prevent misalignment when the first mounting plate 25 moves. When the first mounting plate 25 moves in a circular motion, it drives the first electric telescopic rod 29 to move. The first electric telescopic rod 29 retracts according to the length of the sealing gasket body 6. The first electric telescopic rod 29 scrapes off the oil overflowing around the sealing gasket body 6 through the scraper 210 to avoid affecting the next set of sealing gasket body 6 tests. The scraped oil drips into the collection box 3 for recycling. The support rod 21 provides support for the external gear ring 22 and assists in the stability of its position.
