Problems solved by technology

Due to the lack of a tool that can directly pre-configure the fuel injection advance angle of the diesel engine injector, it is difficult to assemble the fuel injection advance angle of the diesel engine during the assembly process of the diesel engine, so it must be readjusted during the thermal test of the diesel engine The fuel injection advance angle of the fuel injector of the diesel engine requires the disassembly and assembly of diesel engine parts such as the gear chamber cover plate during specific operations. The workload is heavy, which not only affects production, but also causes economic losses.

Abstract

The invention discloses a fuel injection advance angle assembling tool of a diesel engine fuel injector. The fuel injection advance angle assembling tool of the diesel engine fuel injector comprises a base board on which an idle gear is fixed. The base board outside the idle gear is provided with a positioning shaft on which an oil pump gear connector is mounted. The positioning shaft is movably connected with the base board. The positioning shaft is provided with an adjusting handle. The base board at the periphery of the positioning shaft is provided with a reference hole. The base board at the periphery of the reference hole is provided with a plurality of angle positioning holes. The deflection angle of the positioning shaft is fixed through pins which are inserted between the angle positioning holes and the adjusting handle. According to the fuel injection advance angle assembling tool of the diesel engine fuel injector, a fuel injection pump advance angle can be preset according to a technological requirement for a diesel engine, and re-adjustment of the fuel injection pump advance angle in a thermal test is prevented. Not only is a problem of low production efficiency settled, but also consistency and reliability of a product are improved. Furthermore production cost is greatly reduced.

Description

technical field [0001] The invention relates to a diesel engine assembling tool, more specifically, it relates to a diesel engine fuel injector fuel injection advance angle assembling tool. Background technique [0002] In the assembly of diesel engines, there are various installation angles for the injection advance angle of the fuel injector of the diesel engine, such as: 8°, 10°, 12° and more than ten kinds. Its accuracy cannot be guaranteed. Due to the lack of a tool that can directly pre-configure the fuel injection advance angle of the diesel engine injector, it is difficult to assemble the fuel injection advance angle of the diesel engine during the assembly process of the diesel engine, so it must be readjusted during the thermal test of the diesel engine The fuel injection advance angle of the fuel injector of the diesel engine requires the disassembly and assembly of diesel engine parts such as the gear chamber cover plate during specific operations. The workload ...
