This application relates to a common rail diesel engine fuel injector installation and positioning tool, which includes a tool body. The tool body includes a centering part, a measuring part and a tail part. The centering part matches the part where the oil inlet pipe extends into the installation hole of the cylinder head , and can pass through the installation hole and align with the oil inlet hole of the injector. The outer wall of the measuring part is provided with a length scale, and the length scale extends from the zero scale to the centering part along the extension direction of the tool body; when the centering part and the fuel injection When the oil inlet hole of the injector is centered, the zero scale of the length scale is opposite to the end of the installation hole away from the injector. With such a setting, the thickness of the gasket can be quickly and accurately selected through the readings of the measuring part. The operation method is simple and the accuracy is high, and the error caused by the visual method and the waste of manpower and time caused by repeated replacement of the gasket can be avoided. Moreover, it has low requirements for operators, simple and portable structure, and is easy to carry. It can be applied to other center hole alignments with a slight change.
Description
technical field [0001] The present application relates to the technical field of profile diesel engines, and more specifically, relates to a common rail diesel engine fuel injector installation and positioning tool. Background technique [0002] At present, when assembling the fuel injector of the high-speed and high-power high-pressure common rail diesel engine, it is necessary to install the fuel injector and the adjusting gasket to the cylinder head first, and then connect the fuel inlet pipe through the fuel inlet pipe connection installation hole of the cylinder head to connect with the fuel injector. , the center of the fuel injection hole connected to the fuel inlet pipe needs to be aligned with the center of the fuel inlet hole of the fuel injector. The position of the fuel injector in the cylinder head is adjusted by adjusting the thickness of the gasket. cylinder head such as figure 1 shown. [0003] At present, when installing a high-pressure common rail injecto...
