Problems solved by technology

[0003] The most ideal processing method is to make a large-scale special machine to process the main shaft hole, camshaft hole and transmission shaft hole of the diesel engine body in one positioning to ensure the machining accuracy. However, for the high-power diesel engine body, it is difficult to manufacture the special machine due to the large body size. , so far there is no successful case of making a special plane

Abstract

The invention belongs to the technical field of diesel engines, and relates to a machining method of transmission shaft holes of a high-power diesel engine body. The machining method of the transmission shaft holes of the high-power diesel engine body comprises the steps that first, a main shaft hole, a cam shaft hole I and a cam shaft hole II of the diesel engine body are machined; and then the main shaft hole, the cam shaft hole I, and the cam shaft hole II are used as the reference to machine a transmission shaft hole I, a transmission shaft hole II, a transmission shaft hole III and a transmission shaft hole IV. According to the machining method of the transmission shaft holes of the high-power diesel engine body, the dimensional accuracy of the center distance between each shaft holecan be ensured, the coordinate dimension accuracy of the transmission shaft holes can be ensured, and it is of great significance for improving the machining quality of the high-power diesel engine body.

Description

technical field [0001] The invention belongs to the technical field of diesel engines and relates to a processing method for a drive shaft hole of a body of a high-power diesel engine. Background technique [0002] The body is one of the basic parts of the diesel engine and is the skeleton of the diesel engine. Almost all the moving parts and fixed parts of the diesel engine are installed inside and outside. The processing quality of the body directly affects the working performance of the diesel engine. However, the main shaft hole, camshaft hole, and transmission shaft hole where the main shaft, camshaft, and transmission gear are installed on the body have high precision requirements. It only exists on the first gear of the end face of the machine body; in actual machining, it is very difficult to ensure the machining accuracy of the main shaft hole, camshaft hole and transmission shaft hole at the same time. [0003] The most ideal processing method is to make a large-s...
