The tool is applied to the outer conical surface of the steam extraction pipe by using the pressure ring, which not only solves the problem of difficult clamping, but also avoids clamping deformation due to the ring compression. After processing, the parallelism of the two ends of the steam extraction pipe length is within 0.03mm. The special positioning tool for turning the steam extraction pipe of the utility model is used for positioning the steam extraction pipe.
【技术实现步骤摘要】
一种车削抽汽管的专用定位工具
本技术涉及车削抽汽管定位工具领域。
技术介绍
抽汽管为圆锥筒型部件,其长度两端面需进行车削加工处理,以及倒角处理,目前在处理抽汽管时遇到的加工难点是,该部件为薄壁部件,刚性差,装夹时易变形;由于抽汽管外壁为光滑圆锥面,难于装夹固定,因此需要采取适当的工艺措施保证其长度两端面平行装夹以便进一步的加工。
技术实现思路
本技术要解决现有车削抽汽管长度两端面难以装夹固定的技术问题,而提供一种车削抽汽管的专用定位工具。一种车削抽汽管的专用定位工具,包括底座、压环、压板、紧定螺钉和支撑螺钉;其中底座下端平面定位安装在机床工作台上,底座均匀设置多个螺纹孔A,抽汽管放置在底座上,压环的内孔为锥形孔,锥度与抽汽管外圆的锥度相同,压环套装在抽汽管外圆锥面上,多个压板均匀搭架在压环上,压板设置螺纹孔B和紧定螺钉孔,压板的一端搭架在压环上,紧定螺钉穿过压板紧定螺钉孔旋进底座螺纹孔A,支撑螺钉穿过压板螺纹孔B支撑在底座上。进一步的,压环内孔直径大于抽汽管上端外径,小于抽汽管下端外径。进一步的,所述压板数量为至少4个。进一步的,所述压板数量为4~6个。进一步的,所述压板对称均匀设置。本技术的有益效果是:本技术定位工具,底座以下端平面定位安装在机床工作台上,压环的内孔为锥形孔,锥度与抽汽管外圆的锥度相同,利用压环套装在抽汽管外圆锥面上,紧定螺钉穿过压板紧定螺钉孔旋进底座螺纹孔,支撑螺钉穿过压板螺纹孔支撑在底座上,支撑螺钉工作时起辅助支撑作用,利用 ...
