Engine high-pressure oil rail trimming die

Abstract

The invention discloses an engine high-pressure oil rail trimming die which comprises a bottom plate and a fixed structure. A U-shaped seat is arranged on the front side of the middle of the upper surface of the bottom plate, a toothed column is rotatably connected in the U-shaped seat through a bearing, a toothed column motor output shaft arranged on the left side face of the U-shaped seat is fixedly connected with a left rotating shaft of the toothed column, a guide table is slidably connected in a T-shaped sliding groove in the rear side of the upper surface of the bottom plate, a gear motor is arranged in the guide table, an output shaft of the gear motor is rotationally connected with a bottom plate of the guide table through a bearing and extends to the lower side of the guide table,and a gear is arranged at the lower side end of the output shaft of the gear motor. According to the engine high-pressure oil rail trimming die, an engine oil rail can be clamped and fixed, the situation that the machining quality is affected due to position deviation happening to the engine oil rail in the trimming process is prevented, a trimming wheel can conduct comprehensive trimming work onthe engine oil rail, trimming dead corners are avoided, and the trimming quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of engine component manufacturing, in particular to a high-pressure oil rail trimming mold for an engine. Background technique [0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. Engines are suitable for both power generating devices and Can refer to the entire machine including the power plant, such as: gasoline engine, aero engine. [0003] When the engine is working, the fuel rail is needed to provide fuel to each cylinder for combustion and drive the piston to work. The function of the high-pressure fuel rail is to store fuel and suppress pressure fluctuations caused by high-pressure pump fuel supply and injector fuel injection. Make sure the system pressure is sta...

Problems solved by technology

[0004] During the processing of the high-pressure fuel rail of the engine, both ends of the forged high-pressure fuel rail of the engine need to be trimmed. However, the existing trimming mold for the high-pressure fuel rail of the engine is prone to dead corners in the process of trimming, and workers need to manually Trimming work on dead corners increases the workload of personnel
