锥柄套管是车工用于钻孔的常用工具。多年来,装卸钻头一直使用楔铁,不少同志在紧张的生产中极易忽视或丢失楔铁,而用其它工具,甚至用铁块敲打锥柄。久而久之,锥柄套管和钻头的锥柄变得凹凸不平,以致于车床尾座的锥孔接触不良,加之钻削时各表面相互拉磨,影响加工精度,缩短锥柄套管、钻头尾舌的寿命,往往不得不提前报废。因此,我厂革新成一种弹簧锥柄套管。这种新型弹簧锥柄套管,制造简单、使用方便。其结构见图1,在锥柄
Taper shank is a common tool used by turning workers to drill holes. Over the years, loading and unloading drill bits have been using wedge iron, many comrades can easily overlook or lose wedge iron in the intense production, and use other tools, even iron tapping the taper shank. As time passes, the taper shank of the taper shank and the drill bit become uneven so that the taper hole of the tailstock of the lathe is not in good contact with each other, and each surface of the taper shank touches the ground to affect the processing precision, shortens the taper shank, Of life, often have to retire in advance. Therefore, I plant innovation into a spring taper shank casing. This new spring taper shank sleeve, easy to manufacture, easy to use. The structure shown in Figure 1, in the taper shank
