加工 KG 螺纹,手动操作锥度不准确,质量差,废品多。为了保证质量,提高效率,革新成功如图退刀工具。将工具主体装卡在刀架上,挡铁固定在床面。把手柄搬到图示位置,并将靠柱的退刀槽和螺纹要求的长度对好,即可挑扣。退刀后,再将手柄搬到图示位置进行下次挑扣。此工具可加工 L=30mm 左右的 KG 螺纹。挑外扣可利用靠庄上的退刀槽,挑内扣不能自动退刀。
KG thread processing, manual taper inaccurate, poor quality, waste and more. In order to ensure the quality, improve efficiency, the success of the innovation shown in Figure tool. The main tool installed in the tool holder, retaining iron fixed on the bed.
