Expansion tool suitable for machining of air cylinder body of marine large diesel engine

Abstract

The invention discloses an expansion tool suitable for machining of an air cylinder body of a marine large diesel engine. The expansion tool comprises a large-diameter expansion cutter body, a middle adapter and a mandrel joint, wherein the large-diameter expansion cutter body, the middle adapter and a cross joint are connected in sequence, a detachable cutter holder and a detachable blade are arranged on the machining end surface of the large-diameter expansion cutter body, the middle of the large-diameter expanding cutter body is fixedly connected to one end of the middle adapter through a bolt, the mandrel joint is coaxially connected to the other end of the middle adapter, and the large-diameter expanding cutter body and the end of a machining shaft of a machining center are rapidly assembled and connected through the mandrel joint. The expansion tool can be used on the basis that an existing machining center does not need to be changed, machining stability and machining precision can be guaranteed, cost is low, efficiency is high, and assembling operation is easy and convenient.

Description

technical field [0001] The invention relates to machining technology, in particular to an expansion tool suitable for machining cylinder blocks of large marine diesel engines. Background technique [0002] The cylinder block is one of the three major parts of civil products. Since there are many types of cylinder blocks, such as MEC, FLEX, etc., the processing steps of the cylinder block are complicated. With the development of the times and the advancement of technology, the cylinder block has also undergone major changes recently. Compared with the previous cylinder block, the internal structure of the new cylinder block is quite different. Some structures have never been seen before, and there are many processing difficulties. After combining the existing processing tools in the processing workshop, it is found that the existing processing tools cannot meet the processing requirements of the new cylinder block, and cannot solve the processing difficulties, especially the ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide an extended tool suitable for machining cylinder blocks of large marine diesel engines, which can solve the problem that existing machining centers cannot meet the requirements of existing medium and large cylinder blocks.

[0004] Invention principle: While designing the processing tool, it is necessary to consider the processing conditions of the existing machine tool accessories, the convenience of the operator and the cost of the processing tool
