Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
Referring to fig. 1 to 8, the utility model provides a drip-proof device for engine oil filler plugging mechanism mainly comprises automatic plugging mechanism 100, vacuum resorption mechanism 200 two parts. The automatic plugging mechanism 100 is used for plugging the engine oil filling port 15, and is used for preventing oil from splashing out of the cylinder body except for meeting the test requirement, and the composition of the automatic plugging mechanism is shown in fig. 2; the vacuum suck-back mechanism 200 is used for sucking back the oil attached to the sealing gasket (polyurethane sealing gasket 1) of the plugging mechanism into the oil collecting tank 9, and the composition of the vacuum suck-back mechanism is shown in fig. 3.
As shown in fig. 2, the polyurethane gasket 1 is mounted on a mounting plate (fixing plate) 2, and is prevented from rotating by a limit bolt 4, so that the oil groove 11 is always located at the lowest edge of an inclined surface (the end surface of the engine oil filling port contacting with the polyurethane gasket), the mounting plate 2 is connected with a driving cylinder 3 by a screw, and the driving cylinder 3 is fixed on a rack.
As shown in fig. 1, 3 and 8, the vacuum suck-back mechanism 200 is usually installed below the automatic plugging mechanism 100, and the vacuum generator 6, the mini ball valve 7, the oil return pipe joint 8, and the like are installed in the oil collection tank 9. The oil return pipe joint 8 is connected with a return suction pipe 16, and the other end of the return suction pipe 16 is connected with a quick-plugging joint 5.
The polyurethane sealing gasket 1 is manufactured by special die sinking, and the plugging surface 13 is smooth and is provided with an oil groove 11 and an oil return hole 12. The oil groove 11 is positioned at the inner diameter edge of the filling port and ensures the sealing property between the engine filling port and the polyurethane sealing gasket 1 when the sealing and the butt joint are carried out, and the depth H and the width W of the oil groove 11 are about half of the diameter phi 1 of the return suction pipe 16 so as to ensure the maximum return suction force in the oil groove. The oil groove 11 is arc-shaped, the oil return hole 12 is located in the middle of the oil groove 11 (namely, at the arc top), and the diameter can be determined according to the attached oil quantity and related parameters of the vacuum generator.
In the figure, the polyurethane sealing gasket 1 is of a double-layer circular truncated cone structure, the limiting threaded hole is formed in the side end of the narrow circular truncated cone, and in the mounting structure, the narrow circular truncated cone is integrally embedded into the mounting plate 2 (see figure 8).
Further, the diameter 2R (shown schematically as radius R) of the oil groove is smaller than the inner diameter φ 2 of the oil fill port 15, so that the oil can be further collected while maintaining the seal of the seal gasket against the oil fill port.
The electromagnetic valve controls the compressed air to enter the vacuum generator 6 of the vacuum suck-back mechanism 200, and the oil return pipe joint 8 is connected with the quick connector 5 of the automatic plugging mechanism 100 through an air pipe (namely, a suck-back pipe 16) to form a negative pressure loop. After the engine test is completed, the splashed oil can be attached to the polyurethane sealing gasket 1 of the automatic sealing mechanism 100, because the polyurethane sealing gasket 1 is in an inclined state (namely, the sealing surface 13 in the figure is inclined), the attached oil can flow into the arc-shaped oil groove 11 of the polyurethane sealing gasket 1 under the action of gravity and reach the oil return hole 12 at the arc top, and under the action of negative pressure, the oil flowing into the oil groove is sucked back into the oil collecting tank 9 of the vacuum suck-back mechanism 200 through the oil return hole 12, so that a test cycle is completed.
When the anti-dripping device is used for testing an engine, the electromagnetic valve is in a closed state, and the vacuum suck-back mechanism has no negative pressure. After the engine test is finished, the electromagnetic valve is opened, the vacuum suck-back mechanism is in a negative pressure state, the attached oil is sucked back into the oil collecting tank 9, the electrifying time is 6-8S, and the circulation is performed in sequence.
