Method for machining centrifugal cylinder sleeve and integrated tool

Abstract

The invention relates to a method for machining a centrifugal cylinder sleeve and an integrated tool. The method for machining the centrifugal cylinder sleeve comprises the steps that firstly, the inner diameter of the centrifugal cylinder sleeve is machined, then a chamfering being 45 degrees, an R angle being R0.3, an R angle being R0.8, and a chamfering being 22 degrees are machined simultaneously, and finally a chamfering being 60 degrees is machined. The integrated tool comprises a tool holder and a tool bar connected to the tool holder, the end which the tool bar connected to the tool holder is provided with a first fixing portion used for fixing a machining knife, and the other end opposite to the tool bar is provided with a second fixing portion used for fixing the machining knife;the first fixing portion is provided with a first chamfering knife and a forming knife; and the second fixing portion is provided with a second chamfering knife, and one position, close to the secondfixing portion, of the tool bar is further provided with an inner hole knife. The method for machining the centrifugal cylinder sleeve and the integrated tool can realize simultaneous machining of the R angles and the chamferings with different angles of the centrifugal cylinder sleeve, thereby reducing machining steps and shortening the machining time. In addition, machining tools are assembledin the same tool bar, thus reducing the space moving time in the process of machining, so that the working efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of engine production, in particular to a method for processing a centrifugal cylinder liner and an integrated tool. Background technique [0002] The centrifugal cylinder liner is an important component of the engine, together with the cylinder head and the piston, it forms the working space of the cylinder, bears the side thrust of the piston, and becomes the lead of the reciprocating motion of the piston. Centrifugal cylinder liners should have sufficient strength, rigidity and heat resistance, and should also have good wear resistance. In terms of size, sufficient roundness and cylindricity accuracy are required, and the center of the inner hole of the mounting support surface should have high position accuracy. Therefore, there are also high requirements for the processing of centrifugal cylinder liners. In the traditional processing method, it is necessary to perform chamfering at different angles, ar...

Problems solved by technology

Therefore, different tools need to be used in the processing process, and the processing tools need to be replaced when performing different steps. The processing takes a long time and the processing cycle is slow.

However, the distance between the cutter rod and the cutter rod is large, the empty moving path is long, the processing cycle is slow, and the processing efficiency is not high.
