Press fitting tool for thin-walled cylinder sleeve

Abstract

The invention discloses a press fitting tool for a thin-walled cylinder sleeve. The press fitting tool comprises a pressing rod, a supporting plate combination piece, a plurality of supporting rods and a pressing head and sleeve assembly, wherein the pressing rod is in the shape of a threaded shaft; the pressing head and sleeve assembly is barrel-shaped; one end of the pressing head and sleeve assembly is closed; the other end of the pressing head and sleeve assembly is provided with an opening; the supporting plate combination piece is sleeved on the pressing rod; one end of the pressing rod is fixedly connected with the closed end of the pressing head and sleeve assembly; the supporting plate combination piece comprises a bearing pressing plate, a thrust ball bearing, a bearing nut and a supporting plate; and the pressing head and sleeve assembly comprises a pressing head and a sleeve. The press fitting tool has the advantages that press fitting of the cylinder sleeve can be quickly and effectively finished under the condition that an engine is not required to be detached from a whole machine, the press fitting quality is high, the degree of deformation on the cylinder sleeve is low, and the requirement on the quality of the cylinder sleeve after press fitting can be met completely; and an operation process is convenient, and the working efficiency is greatly improved.

Description

Technical field [0001] The invention relates to a pressing tool for thin-walled cylinder liners, in particular to a tool for press-fitting thin-walled cylinder liners during engine maintenance. Background technique [0002] After the engine has been working for a period of time, it is often prone to cylinder pulling failures due to the harsh working environment and the operator’s failure to perform maintenance and repair in time. In most cases, the cylinder liner needs to be replaced; usually for thinner In order to ensure the quality of press-fitting, the wall-type cylinder liner needs to be press-fitted with special equipment, which requires the engine to be removed from the vehicle and then press-fitted. The work is heavy and seriously affects work efficiency. In order to effectively avoid this When the situation arises, it is necessary to design a tool that can press-fit the cylinder liner on the whole vehicle. Summary of the invention [0003] In order to be able to quickly ...
