Method and cutting tool for machining inclined planes of diesel engine base

Abstract

The invention provides a method and a cutting tool for machining large and small inclined planes of a diesel engine base. The cutting tool comprises a special insertion milling cutter, a corn millingcutter and a welding alloy end milling cutter; the insertion milling cutter does feed motion through CNC program instructions in the machining process axially for combined drilling and milling as wellas layered cutting so that rough machining is finished; the corn milling cutter does feed motion radially so that the rough machining of the large and small inclined planes as well as the finish machining of the small inclined plane are finished; the welding alloy end milling cutter does feed motion radially so that the finish machining of the large inclined plane is finished; and thus, the working procedures of rough machining, de-allowance rough machining and finish machining of all large and small inclined planes on the engine base are finished automatically. The cutting tool has the advantages of high safety and efficiency, and continuous automatic machining, and the machining cycle is shortened effectively; the machining quality is ensured, and the labor intensity is reduced; and thecutting tool is especially suitable for machining the large and small inclined planes of large diesel engine base.

Description

technical field [0001] The invention relates to the processing of diesel engine parts, in particular to a method and a cutting tool for processing large and small inclined surfaces of a diesel engine frame, belonging to the technical field of metal cutting. Background technique [0002] Engine base is one of the important parts of marine diesel engine, please refer to figure 1 , the large inclined plane 6 and the small inclined plane 7 are the mating surfaces where the inner bearing seat of the machine base 1 and the bearing cover are installed, the small inclined plane 7 is perpendicular to the large inclined plane 6, and the large inclined plane 6 forms an angle of 25° with the plane of the machine base 1; the crankshaft is installed in the bearing hole , the inner file of the support 1 has two bearing blocks, four large inclined planes 6 and four small inclined planes 7 per cylinder, and the number of cylinders of each support base 1 multiplied by 4 is the total number of...
