Problems solved by technology

[0003] In the prior art, according to the structural strength requirements of the large end of the connecting rod, the width of the large end of a part of the connecting rod will be larger than the inner diameter of the cylinder liner. The sleeve removal method and device can no longer meet the removal requirements of this matching method, and it is necessary to develop a new type of cylinder liner removal device to meet the actual work requirements

Abstract

The invention provides a cylinder sleeve dismounting device. The cylinder sleeve dismounting device comprises pressing devices, friction plates, a base, regulating liner tubes, a pressing nut, a supporting block, a wear reducing device, a rocking bar and a center stud, wherein the center stud is used for sequentially mounting the base, a plurality of pressing device, the pressing nut, the supporting block and the rocking bar from bottom to top; the rocking bar and the pressing nut are both in threaded connection with the center stud; each regulating liner tube is arranged between every two adjacent pressing devices; a cylindrical structure consisting of a plurality of friction plates of which the sections are arc-shaped is arranged at the outer side of each pressing device; the bottom of each friction plate is in contact with the base. The device disclosed by the invention can be used for realizing dismounting of a general cylinder sleeve and also realizing the dismounting of the cylinder sleeve at a condition that the width of a large head of a connecting rod is larger than the inner diameter of the cylinder sleeve; the cylinder sleeve dismounting device is reasonable in structural design and easy to implement.

Description

technical field [0001] The invention belongs to the technical field of engine disassembly tooling, in particular to a cylinder liner removal device. Background technique [0002] The engine cylinder liner is one of the main components that make up the combustion space of the engine. During the combustion process, it not only bears the interactive influence of the high temperature difference on both sides of the wall, but also bears the high temperature gas pressure of tens or even hundreds of atmospheres. The cooperation between the cylinders (referred to as the cylinder clearance) has a very important impact on the engine's work efficiency, piston blow-by and engine oil consumption. Therefore, reducing the amount of deformation produced during the removal of the cylinder liner has a very important impact on improving the stability and service life of the engine's working state. [0003] In the prior art, according to the structural strength requirements of the large end of...
