Description

Technical Field

[0001] The invention relates to the field of engine cylinder processing equipment, and in particular to a cylinder cleaning interlayer device. Background Art

[0002] The cylinder block is the main load-bearing part of the engine. On the one hand, it has to withstand the impact force generated by the explosion of the combustion gas. At the same time, the crank-connecting rod mechanism inside the engine is installed on the cylinder block. The existing engine cylinder body is formed by aluminum alloy die-casting, which has the advantage of reducing the overall weight of the engine. There are multiple channels on the engine cylinder block, which are mainly formed by core-pulling die-casting during die-casting. During the die-casting process, the gap between the front end face of the core-pulling and the joint surface of the mold core is prone to form a partition. After the die-casting is completed, the partition needs to be removed to ensure that the channel is completely through. The existing technology mainly uses a manual handheld grinding head to clean a single channel. This cleaning method is not only inefficient, but also prone to leakage. Summary of the Invention
