Description
The technical field is as follows: the utility model relates to an automobile engine oil pan specifically is an automobile engine oil pan gas tightness detection device.
Background art: the oil pan is a part which is arranged at the bottom of the engine and is used for containing engine oil, the engine oil provides lubrication for all parts of the engine during operation, and the service life of the engine can be prolonged through good lubrication. The air tightness of the oil pan is an important performance index of the oil pan, and the phenomenon of oil leakage caused by unqualified air tightness causes that each part of the engine cannot be effectively lubricated, the service life of the engine is shortened, and the use cost of customers is increased. Most of the pneumatic detection devices are adopted in China at the present stage, but the pneumatic tightness detection devices are high in cost, complex in structure and long in manufacturing period, are not suitable for production and use of sample pieces before the die sinking of new products, and easily cause unnecessary capital investment.
The invention content is as follows: an object of the utility model is to provide a practicality is strong, simple structure, low cost, safe and reliable's automobile engine oil pan gas tightness detection device. The purpose of the utility model is realized like this: the utility model provides an automobile engine oil pan gas tightness detection device, it contains work piece, big pressure head, air cock, bottom surface sealing gasket, the anchor clamps body, little pressure head, little sealed pad, big sealed pad, its characterized in that: the small pressure head is connected with the clamp body through threads, the small pressure head is connected with the small sealing pad through an interference press-in mode, the large pressure head is connected with the clamp body through threads, the large pressure head is connected with the large sealing pad through an interference press-in mode, the air tap is connected with the clamp body through threads, and the air tap is connected with the clamp body through threads; the screw rod is fixedly connected with the nut through the clamp body, the sealing gasket and the workpiece to realize sealing connection. The technical effects of the utility model lie in simple structure, low cost, safe and reliable. The utility model discloses an airtightness detection device, under the prerequisite of guaranteeing to have the same machining precision and stability with pneumatic fixture, make the 1/5 of the pneumatic fixture cost still can not be gone back to whole set of anchor clamps cost, manufacturing cycle is short moreover, and 1 set of anchor clamps of manufacturing just can be produced to the fastest 3 days, easy maintenance, maintenance duration are short, save the fund.
Description of the drawings: FIG. 1 is a schematic front view of the structure principle of the present invention; fig. 2 is a schematic top view of the structure principle of the present invention.
The specific implementation mode is as follows: the utility model provides an automobile engine oil pan gas tightness detection device, it contains work piece 1, big pressure head 2, air cock 5, air cock I6, the sealed 7 of bottom surface gasket, the anchor clamps body 8, little pressure head 9, little sealed 10, the big sealed 11 that fills up of filling up, its characterized in that: the small pressure head 9 is connected with the clamp body 8 through threads, the small pressure head 9 is connected with the small sealing gasket 10 through an interference press-in mode, the large pressure head 2 is connected with the clamp body 8 through threads, the large pressure head 2 is connected with the large sealing gasket 11 through an interference press-in mode, the air tap 5 is connected with the clamp body 8 through threads, and the air tap I6 is connected with the clamp body 8 through threads; the screw rod 4 is fixedly connected with the nut 3 through the clamp body 8, the sealing gasket 7 and the workpiece 1 to realize sealing connection.
The working principle and working process of the present invention will be described in detail with reference to the accompanying drawings.
The working principle is as follows: the workpiece 1 is positioned and clamped in the clamp through the screw rod 4 and the nut 3; the small pressure head 9 is screwed with the clamp body 8 through threads to generate pressing force, the pressing force acts on the workpiece 1 through the small sealing gasket 10 to realize the sealing of the end surface of the threaded hole, the large pressure head 2 is screwed with the clamp body 8 through threads to generate pressing force, and the large pressure head 2 acts on the pressing force on the workpiece 1 through the large sealing gasket 11 to realize the sealing of the end surface of an oil way; high-pressure air is input into a workpiece oil way through an air nozzle 5, the workpiece is detected by utilizing the pressure of the high-pressure air, the internal surface and the air nozzle I6 are observed to be not allowed to leak, the high-pressure air is cut off from the air nozzle 5, the high-pressure air is input into the other oil way of the workpiece 1 through the air nozzle I6 again, the internal surface of the workpiece and the air nozzle 5 are detected by utilizing the pressure of the high-pressure air to be not allowed to leak, and the air tightness of.
The working process is as follows: the workpiece 1 is positioned and compressed in the device through the bottom surface sealing gasket 7, the screw rod 4 and the nut 3, and meanwhile, the workpiece 1 and the clamp body 8 are connected through the bottom surface sealing gasket 7; the small pressure head 9 is connected with the clamp body 8 through threads, and the small pressure head 9 is screwed to enable the small sealing gasket 10 to generate pressing force, so that the end face of the threaded hole of the workpiece 1 is sealed; the large pressure head 2 is connected with the clamp body 8 through threads, and the large pressure head 2 is screwed to enable the large sealing gasket 11 to generate pressing force so as to seal the end face of the oil disc of the workpiece 1; compressed air is input into an oil path of the workpiece 1 through the air faucet 5, the air sealing device is placed into water to observe that the inner wall of the workpiece 1 and the air faucet I6 are free of air leakage, the air is compressed after the air sealing device is broken, then the compressed air passes through another oil path of the workpiece 1 through the air faucet I6 again, the air sealing device is placed into water to observe that the inner wall of the workpiece 1 and the air faucet 5 are free of air leakage, and air tightness detection is qualified. The large pressure head 2 and the small pressure head 9 are reversely unscrewed and the nut 3 is loosened, so that the workpiece dismounting process is realized.
