Description
Technical Field
The invention relates to the field of automobile fuel systems, in particular to an automobile fuel tank thimble height detection tool.
Background
In recent years, with the rapid development of the automobile industry, the number of automobiles has been drastically increased, and the environmental problems caused thereby have been increased. For this reason, the national environmental protection department and the national quality supervision and inspection and quarantine administration jointly issue "light automobile pollutant emission limit and measurement method (sixth stage of China)" in the year 2016, 12 and 23, and issue the emission requirement and implementation time of the light automobile in the sixth stage. Since 7/1/2020, all light vehicles sold and registered should meet the national sixth standard. Compared with the prior vehicle type, the total hydrocarbon emission of the six vehicle types is reduced by more than 50 percent. In order to meet the requirements of the national sixth emission standard, the structure of the automobile fuel tank is greatly changed, wherein the biggest change is the locking mode of the oil pump. A sealing ring is arranged on the outer ring of an oil pump port, and then the upper part of the sealing ring arranged on the oil pump is tightly locked and sealed with the oil tank pump port through a plastic nut. The problem that this kind of mounting means exists is that plastics nut generally can appear obvious moment decay after 24 hours to there is expend with heat and contract with cold phenomenon along with the temperature variation, and the car is in operation because vibration simultaneously also can cause not hard up, thereby influences sealed effect, leads to discharging great. The novel Guohu oil tank is tightly sealed in a locking mode of a metal caulking ring and a clamping ring, the metal caulking ring is firmly welded on the oil tank through a robot when the fuel tank is in blow molding, then the sealing ring is placed into the caulking ring when the fuel tank is assembled, and the clamping ring and the caulking ring are locked together by using larger installation force after the sealing ring is placed into the fuel pump. Therefore, moment attenuation and thermal expansion and contraction phenomena can not occur, and the emission is reduced. However, if the quality of the embedded ring is unqualified, or the embedded ring is clamped by a robot in the welding process and is not matched with the size of the clamping ring, the oil pump cannot be normally installed, or a large gap exists after the assembly, so that the discharge exceeds the standard, and even an oil leakage accident occurs in serious cases.
