Problems solved by technology
However, with the increase in the output of diesel engine cylinder heads, the resources of the five-axis CNC machining center can no longer meet the needs of production. In order to solve the bottleneck problem of existing processing equipment, ensure the completion of the processing plan, and share the pressure of the five-axis CNC machining center, It is necessary to complete the machining of the valve hole by other boring machines without turntables, such as PAMA boring machines

The invention discloses a tool and method for processing a valve hole of an air cylinder cover of a marine diesel engine. The tool comprises a bottom plate, two side plates, two end plates, a supporting block, a middle block, two rollers and two shafts, wherein the bottom plate is horizontally placed on a workbench of a boring machine, and the two side plates are vertically and fixedly connected to the two side edges of the bottom plate respectively in the long edge direction; the two end plates are vertically and fixedly connected to the two end edges of the bottom plate respectively in the short edge direction, the two sides of the end plates are fixedly connected with the two side plates respectively, and the middle block is fixedly mounted in the center of the bottom plate; the supporting block is connected to the upper portion of the middle block through a vertical bolt and used for supporting the air cylinder cover, and lifting of the supporting block can be adjusted by rotating the bolt; and the two shafts horizontally and transversely penetrate through the side plates on the two sides of the middle block respectively, the two rollers are arranged on the two shafts respectively in a sleeving mode and rotate on the shafts, and the air cylinder cover is placed on the two rollers and can roll. The application of the turntable-free boring machine to process the valve hole of the air cylinder cover is realized, and the effects of reducing the cost, optimizing the process, shortening the period and ensuring the quality are achieved.
Description
technical field [0001] The invention relates to the processing of a cylinder head of a marine diesel engine, in particular to a tooling and a method for processing a valve hole of a cylinder head of a marine diesel engine, and belongs to the technical field of diesel engine manufacturing. Background technique [0002] The machining of the valve hole on the cylinder head of the existing marine diesel engine is generally carried out by a five-axis CNC machining center, because the machining of the cylinder head valve hole involves determining the position of the hole through multi-angle rotation, and the five-axis CNC machining center does not need to use auxiliary positioning Tooling can be processed. However, with the increase in the output of diesel engine cylinder heads, the resources of the five-axis CNC machining center can no longer meet the needs of production. In order to solve the bottleneck problem of existing processing equipment, ensure the completion of the proce...
