Description

technical field [0001] The invention belongs to the technical field of diesel engine processing, and specifically relates to a device and method for processing the cylinder bore surface of a V-type diesel engine, which can ensure the surface milling of the two-row cylinder bore surface of the V-type diesel engine fuselage and the rough and fine boring of the cylinder bore and the seam (Mainly because the A-row and B-row cylinder bore surfaces of the V-type diesel engine fuselage are two 26° symmetrical planes, and the processing elements such as flatness, symmetry, and shape and position tolerance of the cylinder bore have relatively high requirements). Background technique [0002] On the V-type diesel engine body, there are two rows of cylinder hole face milling and rough and fine boring cylinder holes and seams (mainly because the A-row and B-row cylinder bore surfaces of the V-type diesel engine body are two symmetrical planes of 26 degrees, the plane It is one of the bo...

AI Technical Summary

Problems solved by technology

[0002] There are two rows of cylinder hole face milling and rough and fine boring cylinder holes and spigots on the V-type diesel engine body (mainly because the A-row and B-row cylinder bore surfaces of the V-type diesel engine body are two symmetrical planes of 26 degrees, the plane degree, symmetry, and shape and position tolerance of the cylinder bore and other processing elements have high requirements) and the processing accuracy is relatively high, which is one of the bottlenecks in the processing of the entire fuselage. It is difficult to guarantee the positional accuracy of the holes during sub-process processing

It is troublesome to align the above parts before processing. When processing the hole system on the CNC machine tool, because the accessory (machine tool spindle) of the machine tool is processed vertically downward, it cannot be turned into a 26° surface, so the V-type diesel engine cylinder hole Surface processing is very difficult, and the 26° cylinder bore surface of this type of diesel engine has the problem that the symmetry of the two rows of cylinder bore surfaces is out of tolerance. It can only be exposed during the assembly process of the diesel engine, which seriously restricts the normal production of the diesel engine body. Therefore it is necessary to improve
