Spring retainer groove of valve and stem end processing device for internal combustion engine

摘要

The subject innovation enhances the extent that, more specifically, machining concentricity and Lee mutator fixing groove consideration of the spring retainer screw hole of the valve and the stem end (chamfering) of the processing apparatus for making an intake, an exhaust valve used in the engine It relates to the processing unit of the valve that allows accurate and fast processing.; In Sikkim the subject innovation is to form a spring retainer fixed groove and the stem end (chamfered) to a valve, interposed between the reference roller and a pressure roller which is fixed to move the compaction roller rotation without and so the valve is rotating, being moved between the rollers by the grinding wheel from the side of the valve to be moved toward the valve stem was formed a fixing groove and the stem end is hameuroseo be made to reverse the same time the pressure roller to reverse the grindstone.; That is, the subject innovation will be the work done with the conventional method is fixed to the reference roller, unlike that in use the process that after the reference roller and the pressure roller is work done by moving toward the grindstone original position and moves the pressure roller and the grinding wheel to provide a step for the spring retainer fixed to the stem end groove elapsed (chamfered), and can be accurately and easily formed in the concentricity of the spring retainer screw hole.
