在机械加工过程中,常常会遇到一些不通孔的螺孔零件,由于带有复杂特殊形面的外形,因而不便在组合机床上进行攻丝。如用手攻丝,不仅效率低,劳动强度大,而且还容易攻偏螺孔,折断丝锥,影响零件质量。本文介绍一种安装钻床主轴上,在不改变钻床主轴转向,攻丝到预定深度,丝锥能自动反转退出零件孔的自动攻丝夹具。
In the machining process, often encounter some non-through hole screw hole parts, due to the complex shape of the special shape of the surface, thus making it difficult to tap the combined machine. Such as hand tapping, not only inefficient, labor-intensive, but also easy offensive screw hole, broken tap, affecting the quality of parts. This article describes an installation of drilling spindle, without changing the drilling spindle, tapping to a predetermined depth, the tap can automatically reverse the exit hole parts tapping fixture.
