Air cylinder sleeve finish machining process

Abstract

The invention discloses an air cylinder sleeve finish machining process. The air cylinder sleeve finish machining process adopts a following air cylinder sleeve finish machining treatment device. Theair cylinder sleeve finish machining treatment device comprises a base, a fixing device, clamping devices and a machining device, the fixing device is fixedly installed on the base, and the clamping devices are installed at the two sides of the fixing device; and the machining device is installed on the base and comprises a grinding mechanism, a honing mechanism and a machining power mechanism. The air cylinder sleeve finish machining process adopting the air cylinder sleeve finish machining treatment device comprises the following steps that S1, air cylinder sleeves are fixed; S2, clamping and positioning are carried out; and S3, inner wall treatment is carried out. According to the air cylinder sleeve finish machining process, the air cylinder sleeves of different sizes and specifications can be clamped and fixed through cooperation of the fixing device and the clamping devices, the application range of the air cylinder sleeve finish machining process is enlarged, the machining device can repeatedly conduct grinding and honing work on the inner walls of the air cylinder sleeves at the same time, the working efficiency is improved, and the machining effect is improved.

Description

technical field [0001] The invention belongs to the technical field of cylinder liner processing, in particular to a cylinder liner finishing process. Background technique [0002] The cylinder liner is a cylindrical part, which is placed in the cylinder block hole of the machine body, and is pressed and fixed by the cylinder head. It forms the combustion chamber together with the piston and the cylinder head. The cylinder liner is divided into two categories: dry cylinder liner and wet cylinder liner. , the cylinder liner whose back does not contact the cooling water is called a dry liner, and the cylinder liner whose back is in contact with the cooling water is a wet liner. The dry liner is thinner, simple in structure, and easy to process. The wet liner directly contacts the cooling water, so there are It is beneficial to the cooling of the engine, and is beneficial to the miniaturization and weight reduction of the engine. Due to the complex working environment of the c...

AI Technical Summary

Problems solved by technology

[0004] 1. It is difficult to fix the cylinder liner during manual grinding, so the cylinder liner shakes or swings during the grinding process, which affects the grinding quality. The initial grinding quality affects the effect of subsequent fine honing, and the labor efficiency is low, time-consuming and laborious

[0005] 2. It is often difficult to adapt to cylinder liners of different sizes when the machine is polished, and the adaptability is poor, and the next step of fine honing can only be carried out after the machine is polished, which is inefficient
