Description

Technical Field

[0001] This utility model relates to the field of engine repair equipment technology, specifically to an engine cylinder block and cylinder liner installation device. Background Technology

[0002] Currently, engine overhauls require cylinder liner replacement. Existing technology involves the following methods: first, the entire engine block is frozen with liquid nitrogen or heated in an oven; then, technicians use a sledgehammer to hammer the cylinder liner into the cylinder. Liquid nitrogen freezing results in wasted liquid nitrogen evaporation, and after oven heating, the cylinder liner needs to cool naturally for two hours before proceeding to the next step. Furthermore, heating, liquid nitrogen freezing, and hammering all cause cylinder liner deformation, and hammering can cause permanent damage to the cylinder block, hindering secondary machining. In summary, existing cylinder liner replacement techniques are labor-intensive for technicians and easily damage both the cylinder liner and the cylinder block. Therefore, a new cylinder liner installation device is needed to solve these technical problems. Utility Model Content

[0038] The technical effects achieved by this embodiment are as follows: the bearing platform 2 has a simple structure and is easy to process and manufacture. At the same time, it can quickly adjust the position of the engine cylinder block during use so that each cylinder liner can be pressed in one by one.

[0039] Example 3

[0040] like Figures 1 to 7As shown in the figure, another engine block and cylinder liner mounting device provided in this embodiment has the same structure as in embodiment 1. Only the different parts are described below.
