Narrow groove of axle head portion mouth quenching inductor

The utility model relates to a heating inductor technical field especially relates to a narrow groove of axle head portion mouth quenching inductor. Connect inductor bottom plate and induction coil'sconnecting wire including inductor bottom plate, induction coil and being used for, still include the magnetizer, the induction coil level set up in connecting wire's below, and with connecting wire forms an annular structure, the magnetizer level is fixed induction coil's top. The induction coil of bottom together with the magnetizer can imbed wait to process the notch of work piece in to heat tothe notch wall, and avoid heating the terminal surface of whole axle, can effectually prevent that notch closed angle department from producing embrittlement. 本实用新型涉及加热感应器技术领域，尤其涉及种轴端部窄槽口淬火感应器。包括感应器底板、感应线圈和用于连接感应器底板与感应线圈的连接导线，还包括导磁体，所述感应线圈水平设置于所述连接导线的下方，且与所述连接导线形成个环状结构，所述导磁体水平固定在所述感应线圈的顶部。底部的感应线圈连同导磁体能够嵌入待加工工件的槽口内，从而针对槽口壁进行加热，而避免对整个轴的端面进行加热，能有效的防止槽口尖角处产生脆裂。
