However, the existing positioning and fixing device for the high-pressure common rail injector has the following problems in the use process:
1. when most high-pressure common rail oil injectors in the current market are used, the existing oil injectors are fixed by pressing and fixing an oil injector clamp through a single bolt, and in the process of assembly or use of a production line, the installation angle of the oil injector clamp has randomness or rotates, so that the oil injection angle of the oil injector is changed, and the atomization of fuel oil and the performance of an engine are influenced;
2. in most high-pressure common rail fuel injector positioning and fixing devices in the market at present, a fuel injector clamp is fixed through a single bolt, and the installation angle of the fuel injector clamp can be executed without standards in a production line or a maintenance process;
3. in most high-pressure common rail oil sprayer positioning and fixing devices in the market at present, the mounting surface of an oil sprayer is inclined possibly due to the randomness of the mounting angle of an oil sprayer clamp;
4. in most high-pressure common rail oil sprayer positioning and fixing devices in the market at present, because the oil sprayer clamp is lack of positioning design, the oil sprayer clamp is directly contacted with an oil sprayer, excessive vibration of an engine can be conducted to the oil sprayer, and the timing and the oil spraying quantity of the oil sprayer are influenced;
5. most high pressure common rail fuel injector location fixing device in the existing market, the oil spout clip lacks the location design, leads to the installation angle uniformity of sprayer poor to lead to the uniformity of engine performance poor.
SUMMERY OF THE UTILITY MODEL
