Problems solved by technology

[0002] The multi-cylinder machine is an important equipment, and many problems will be encountered in the processing of the multi-cylinder machine, especially in the processing of the bottom surface and holes of the multi-cylinder machine. After the bottom surface is processed, the hole The machining will cause damage to the hole position on the plane. These are all problems that we need to solve and change the machining process to improve the machining effect of the multi-cylinder machine.

Embodiment 1

[0016] A method for processing the bottom surface of a body of a multi-cylinder machine and the positioning holes on the bottom surface, the specific steps of the processing method of the bottom surface of the body of the multi-cylinder machine and the positioning holes on the bottom surface are as follows:

[0017] S1: Carry out rough milling on the top surface of the multi-cylinder machine. The feed rate of rough milling is 2mm, and the rough milling is performed twice. Fine grinding is carried out after fine milling, and the surface roughness after fine grinding is less than 1.6;

[0018] S2: Position the multi-cylinder machine, use a special fixture, and use the top surface of the multi-cylinder machine as the positioning reference for positioning. After the positioning is accurate, clamp the multi-cylinder machine to avoid large errors in processing caused by insufficient clamping force;

[0019] S3: Carry out rough milling on the bottom surface of the multi-cylinder mach...

Abstract

The invention discloses a processing method of a bottom surface and a positioning hole in the bottom surface of an engine body of a multi-cylinder engine. The processing method comprises the following steps that S1, the top surface of the multi-cylinder engine is roughly milled; S2, the multi-cylinder engine is positioned; S3, the bottom surface of the multi-cylinder engine is roughly milled; S4, a cast reserved hole in the bottom surface of the multi-cylinder engine is processed; S5, the bottom surface of the multi-cylinder engine is finely ground after the cast reserved hole is processed; and S6, the bottom surface and the hole in the bottom surface of the multi-cylinder engine are detected. The top surface of the multi-cylinder engine is finely processed in advance, the multi-cylinder engine is accurately positioned by using the top surface as a precise primary standard, the bottom surface of the multi-cylinder engine is convenient to process, alternately processing of the bottom surface of the multi-cylinder engine and the hole in the bottom surface is conducted, the bottom surface of the multi-cylinder engine and the hole in the bottom surface are prevented from being damaged in processing, and the processing precision of the bottom surface is ensured.

Description

technical field [0001] The invention relates to the technical field of multi-cylinder machining, in particular to a method for processing the bottom surface of a body of a multi-cylinder machine and positioning holes on the bottom surface. Background technique [0002] The multi-cylinder machine is an important equipment, and many problems will be encountered in the processing of the multi-cylinder machine, especially in the processing of the bottom surface and holes of the multi-cylinder machine. After the bottom surface is processed, the hole The processing will cause the hole position on the plane to be damaged. These are all problems that we need to solve and change the processing procedure to improve the processing effect of the multi-cylinder machine. Contents of the invention [0003] The object of the present invention is to provide a kind of body bottom surface of multi-cylinder machine and the processing method of the positioning hole of bottom surface, the proce...
