Description
Technical Field
The invention relates to a precise separator assembly mistake-proofing structure of an automobile oil-gas separator.
Background
Energy conservation and emission reduction become common subjects of the automobile industry in the world, and strict emission regulations continuously improve the performance requirements of crankcase ventilation systems of automobiles. The oil-gas separator is an essential functional component forming a crankcase ventilation system in a plastic valve chamber cover, and has important influence on the stability and safety of the engine operation. When the engine works, a part of high-temperature and high-pressure fuel gas leaks into a crankcase through a piston ring, wherein after gasoline vapor and water vapor are condensed, engine oil becomes thin, the performance is deteriorated, foams are formed in the engine oil to damage the normal supply of the engine oil, and the phenomenon is particularly serious when the engine is cooled in winter. After the oil-gas separator is installed, engine oil in oil gas discharged from a crankcase can be separated and reserved back to an oil pan, so that after the oil-gas separator is separated, mixed waste gas, oil vapor, incompletely combusted CO and other fuel gas enter an air inlet of a supercharger through corresponding pipelines to be mixed with air, and the mixture is pressurized and then enters a human cylinder to be combusted secondarily. Therefore, in the design and development process of the crankshaft ventilation system, the design and performance research of the oil-gas separator is one of the most important links.

"this patent document discloses a good oil-gas separator, but this patent document only discloses an oil-gas separator for vehicles, and does not relate to how to prevent the occurrence of misloading when the fine separator is installed, and if the misloading occurs, the problems that the sample piece has cracks or the oil-gas separation efficiency does not reach the standard occur, so that the problems that customers complain about and the like occur can be caused.
Disclosure of Invention
The invention aims to provide an oil-gas separator assembly mistake-proofing structure which can effectively prevent the occurrence of installation errors when a fine separator and a lower shell of the oil-gas separator are connected together during the production and assembly of the oil-gas separator.
The technical scheme adopted by the invention is as follows: a precise separator of an oil-gas separator is provided with an error-proofing structure, and the precise separator comprises a precise separator body, a fiber cotton body and a supporting plate. The fine separator body is provided with a right installation mistake proofing column and a left installation mistake proofing column. The cross sections of the right installation mistake-proofing column and the left installation mistake-proofing column are rectangular. The upper surface of the rear end of the right installation mistake-proofing column is attached to the lower surface of the right end of the front crosspiece at the upper end of the fine separator body and fixedly connected together, and the front end of the right installation mistake-proofing column is located in front of the front side face of the front crosspiece. The left end of the rear crosspiece at the upper end of the fine separator body is established to left side installation mistake proofing post, and the front end of left side installation mistake proofing post links firmly with the rear surface laminating of rear crosspiece together, and the lower surface of left side installation mistake proofing post flushes with the lower surface of rear crosspiece.
Preferably, the fine separator body, the right installation mistake-proofing column and the left installation mistake-proofing column are of an integrated structure. Namely, the material of the fine separator body, the right installation mistake-proofing column and the left installation mistake-proofing column is the same, and the material is preferably PA66 GF 30.
Preferably, the right side surface of the right installation mistake-proofing column and the right side surface of the right end of the front crosspiece are coplanar, and the distance from the front side surface of the right installation mistake-proofing column to the front side surface of the front crosspiece is more than or equal to 1.5 mm.
Preferably, the left side surface of the left installation mistake-proofing column is flush with the left side surface of the rear crosspiece, and the length of the left installation mistake-proofing column is greater than or equal to 0.8 mm.
The oil-gas separator comprises an upper oil-gas separator shell and a lower oil-gas separator shell, a left clamping groove and a right clamping groove which are used for being connected with the lower end of the fine separator are formed in the lower oil-gas separator shell, the left end and the right end of the fine separator are correctly inserted into the corresponding left clamping groove and the right clamping groove, the next assembly operation can be carried out, and the lower oil-gas separator shell cannot be damaged. However, in actual production, the left end or the right end of the fine separator is often inserted into the corresponding left clamping groove and the right clamping groove, and for various reasons, an operator often fails to find the wrong insertion and forcibly presses the fine separator downwards, so that the lower shell of the oil-gas separator is easily damaged, unnecessary economic loss is caused, and even if the damage is not caused, the next operation is influenced, the production efficiency is reduced, and unnecessary economic loss is caused. According to the oil-gas separator, the right installation error-proof column and the left installation error-proof column are arranged on the fine separator, and once the left end or the right end of the fine separator is not correctly inserted into the corresponding clamping groove on the lower shell of the oil-gas separator, the lower surface of the corresponding installation error-proof column can touch the upper end surface of the corresponding clamping groove, so that an operator can easily find that the installation operation is wrong, timely correction is carried out, and the installation quality and the efficiency of the oil-gas separator are greatly improved. Therefore, the invention is a very excellent fine separator assembly mistake-proofing structure of the oil separator.
