为了对活动座25和打磨头19进行移动限位,所述活动座25的上下两侧分别设有一个限位滑块24,限位滑块24为半圆柱形结构,限位滑块24、活动座25和打磨头19一体加工成型,所述伸缩槽20的上下两侧分别开设有与限位滑块24配合滑动的限位滑槽23,且当所述限位滑块24位于限位滑槽23外端时(如图5所示),打磨头19从钻头15侧面完全伸出,活动座25完全位于伸缩槽20内;当所述限位滑块24位于限位滑槽23内端时,打磨头19和活动座25完全位于伸缩槽20内。在实际应用时,也可将限位滑块24设置于打磨头19的前后两侧,同时对应设置限位滑槽23即可。
该管材自动化钻孔装置,在实际应用时,具有以下突出优点:
1)通过导料管2的结构设置,利于对管材1导向及限位,方便进行钻孔加工;通过在加工缺口17两侧设置夹紧组件,具有对管材1较佳的辅助固定效果;
2)通过第一伸缩缸4工作可带动顶板5上下移动,利于通过钻头15进行钻孔加工;在第一伸缩缸4的前后两侧设置固定板3,可提升第一伸缩缸4和导料管2的稳定性;
3)通过驱动机构带动钻杆14旋转,以及通过第一伸缩缸4带动顶板5上下移动,即可通过钻头15作用到加工缺口17内对管材1进行钻孔加工,方便快捷;
4)在钻孔加工后,控制第一伸缩缸4继续收缩,同时控制气泵13加压作业,因连接管12、第二空腔27、第一空腔26和伸缩槽20连通设置,打磨头19和活动座25构成的整体可从伸缩槽20伸出;当打磨头19伸出时位于管材1的外侧,可通过收缩控制第一伸缩缸4,利用打磨头19的下部对孔洞的外表面边缘进行修磨;当打磨头19伸出时位于管材1的内侧,可通过伸长控制第一伸缩缸4,利用打磨头19的上部对孔洞的内表面边缘进行修磨;修磨完毕后,控制气泵13负压作业,打磨头19和活动座25构成的整体即可重新容置于伸缩槽20内;通过限位滑槽23和限位滑块24的设置,可对打磨头19的移动进行限位,提升工作稳定性;
5)设置钻杆14和钻头15之间可拆卸连接,方便对钻头15进行拆卸更换,以进行不同尺寸的钻孔加工,此时打磨头19的尺寸进行适应设置即可,不再进行赘述。
以上的仅是本发明的优选实施方式,应当指出,对于本领域的技术人员来说,在不脱 离本发明构思的前提下,还可以作出若干变形和改进,这些也应该视为本发明的保护范围,这些都不会影响本发明实施的效果和专利的实用性。
