Embodiment Construction

[0024] Such as figure 1 As shown, the piston cylinder liner processing technology of the present invention includes the following steps: step a, rough boring inner hole; step b, rough turning small end face and outer circle; step c, rough turning large end face; step d, artificial aging; step e , semi-fine boring and boring the inner hole; step f, semi-finishing the outer circle and end face; step g, finishing small end and chamfering; step h, semi-finishing the hole; step j, finishing turning the outer circle and large end face; step k , fine grinding hole; step L, inspection; step m, drilling; step n, countersinking, chamfering; step o, tapping; step p, hole deburring, chamfering; In a furnace with a temperature lower than 205°C, heat the casting slowly, and keep it at 592±27°C for at least 2 hours. Calculate the holding time according to the maximum central section size of the casting. Every 25mm needs to be kept warm for 1 hour to calculate the holding time. Cool in the fu...

Abstract

The invention discloses a processing process of a piston cylinder sleeve, comprising the following steps of: a, roughly boring an inner hole; b, roughly turning a small end surface and an excircle; c, roughly turning a large end surface; d, carrying out artificial aging; e, half finely boring the bored inner hole; f, half finely turning the excircle and the small end surface; g, finely turning the small end, and chamfering; h, half turning a hole; j, finely turning the excircle and the large end surface; k, finely grinding the hole; L, detecting; m, drilling; n, reaming the hole, and chamfering; o, tapping; and p, burring and chamfering an orifice. The processing process of the piston cylinder sleeve has the advantages of high processing accuracy, strict process flow and higher quality of processed products.

Description

technical field [0001] The invention relates to a process for processing a piston cylinder liner. Background technique [0002] The traditional piston and cylinder liner processing technology, because the process flow is not fine enough, and the process requirements in the artificial aging link are not accurate, resulting in insufficient precision of the piston and cylinder liner processed by this processing technology, and the product quality is poor. Contents of the invention [0003] The purpose of the present invention is to provide a piston cylinder liner processing technology. [0004] The technical solution adopted by the present invention to achieve the above object is: a piston cylinder liner processing technology, comprising the following steps: [0005] Step a, rough boring the inner hole; [0006] Step b, rough turning the small end face and outer circle; [0007] Step c, roughing the large end face; [0008] Step d, artificial aging; [0009] Step e, semi...
