Description

管道钻孔机 技术领域
本发明涉及管道钻孔机，属于钻孔装置技术领域。
背景技术
管道钻孔技术领域中，现有结构形式的钻孔机一般包括以下结构形式：在钻孔过程中需要采用辅助工装实现对工件的夹紧，结构形式复杂，使用起来非常的不方便，且采用辅助工装的结构形式装夹时容易造成管道夹持位置发生跑偏，对钻孔质量造成严重影响。
同时现有技术中的管道钻孔机电源连接软管为一体式结构形式，因为电源线内置在连接软管内，因此电源线发生损伤时无法进行维修，只能更换整根连接软管，浪费现象严重，且影响管道钻孔机的钻孔效率，需要进一步改进。
发明内容
本发明针对上述缺陷，目的在于提供一种结构合理，能快速、准确的对工件管道进行夹持，以及方便对电源线进行维护的管道钻孔机。
为此本发明采用的技术方案是：所述钻孔机包括驱动装置(1)，由所述驱动装置(1)驱动上下运动的钻头(2)，以及设置在所述钻头(2)侧部的夹持部(3)；
所述夹持部(3)包括和管道(4)外轮廓对应的呈内凹的的圆弧卡槽(31)，所述圆弧卡槽(31)两侧设置有夹持座(5)，所述夹持座(5)上设置有用于夹持管道(4)的链条(6)。
所述一侧的夹持座(5)上开设有安装孔(51)，所述安装孔(51)上穿设有链轴(61)，所述链轴(61)上安装有链环(62)，所述链条(6)的另一端端部设置有夹持钩(7)，所述夹持钩(7)钩持在另一侧的夹持座(5)上。

所述驱动装置(1)上连接有用于和电源连接的软管(8)，所述软管(8)分段设置，两段之间通过连接管(9)进行连接，所述连接管(9)内设置有用于导电的导电体(91)。
所述连接管(9)包括对应设置的公插头(92)和母插头(93)。
所述圆弧卡槽(31)内壁设置有突出所述内壁的凸块(32)，相邻两凸块(32)之间设置有磁性快(33)。
所述凸块(32)表面设置有若干小凸点，设置有弹性垫(11)覆盖在所述凸块(32)的表面并由所述小凸点顶出。
