提高钳工钻孔加工质量的方法研究

Research on the Methods of Improving the Quality of Drilling by Locksmiths

在机械设备中,零件、构件、部件之间的连接多是依靠孔来实现的。孔加工是钳工操作的基本技能之一,是钳工作业中最常见的一道工序。孔的尺寸精度和位置精度受到钻床精度、划线精度、冲眼精度、麻花钻刃磨质量、工装夹具应用和钻削参数的选用等因素的影响,钳工作业手工操作需要一定的加工技巧和必要的保证措施,有效避免孔的尺寸精度和位置精度出现超差现象。

In mechanical equipment,the connections between parts,artifacts,and assembly units are mostly realized by holes.Hole processing is one of the basic skills of fitter operation,and it is the most common process in clamp work.The dimensional accuracy and position accuracy of the hole are affected by factors such as drilling machine ac⁃curacy,scribing accuracy,punching accuracy,twist drill sharpening quality,tooling and fixture application,and se⁃lection of drilling parameters,and the manual operation of the clamp work requires certain processing skills and nec⁃essary guarantee measures to effectively avoid the phenomenon of out of tolerance in the dimensional accuracy and position accuracy of the hole.
