AI Technical Summary

Technical Problem

Deep hole grinding operations, especially the wear of the sealing cone surface of the injector hole in the cylinder head of diesel engines, are difficult to achieve with precision grinding, leading to sealing failure.

Method used

A grinding tool was designed, comprising a flange, guide sleeve, cone sleeve, positioning cone, drive shaft, clamping block, and abrasive paper. The drive shaft drives the abrasive paper to precisely grind the sealing cone surface. The use of a locking ring and lubricating grease ensures the stability and wear resistance of the tool.

Benefits of technology

It enables convenient and precise grinding of the sealing cone surface of the injector hole in the diesel engine cylinder head, ensuring sealing performance. The tool has a compact structure, is easy to operate, and occupies little space.

Abstract

一种用于船用柴油机缸盖喷油器孔密封锥面的研磨工具,包括法兰、导向套、锥套、定位锥筒、传动轴、夹块和研磨砂纸;其中,法兰固定于缸盖上,导向套设于喷油器孔中,上部与法兰固定,下部的倒锥体紧贴喷油器孔的倒锥面,对导向套进行中心定位,锥套的上平面紧贴法兰,外圆与喷油器孔壁贴合,定位锥筒连接于法兰下方且套置于导向套与锥套之间,定位锥筒向上顶抵锥套,通过锥套的内圆锥面与定位锥筒的外圆锥面的相互作用,对导向套进行中心定位,传动轴穿置于导向套的中心孔内且以该中心孔定中心,下端轴头的倒圆锥体的圆锥角与密封锥面相对应,上端伸出缸盖的上平面,研磨砂纸通过夹块固定于传动轴的轴头上且紧贴密封锥面;本发明结构紧凑,操作简单,实现了喷油器孔中密封锥面的方便精准研磨。
