Abstract

本发明涉及一种手提式冲击钻,具有能防止沿园周方向转动且通过摆动体而转换成往复运动的传动件,例如其形状可以是空心活塞形。本发明的任务是制造一种传动件防转安全装置,该传动件可在摆动体的带有凸肩的冲击杆作用下移动,此装置的结构要简单,易于装配并且不会脱开保险。本发明对上述任务所做出的解决方案是使冲击杆(6)的凸肩(13)位于两根成一定间距平行排列的销钉(14、15)之间,销钉的一端固定在传动件(1)的后壁(16)内,另一端固定在传动件后部凸台的尾壁(17)内。

Description

带有防转传动件的手提式冲击钻
本发明涉及一种带有冲击器的手提式冲击钻,该冲击钻装有一个位于圆形气缸内的活塞形传动件,该传动件可以在压缩空气的作用下驱使一个能沿轴向自由运动的冲击体做往复运动,冲击体将其能量以轴向冲击的形式传递给安装在冲击钻上的刀具,通过一个摆动体将电动机的旋转运动转换成传动件的振摆运动,摆动体上带有一个沿径向设置的球头冲击杆,该冲击杆的球头安装在活塞形传动件后部的凸台内,冲击杆沿径向自球头处向外延伸出一凸肩,该凸肩在传动活塞后部的凸台内不能进行切向运动。
从US-PS4456076专利文件已知一种冲击钻,这台冲击钻传动件(空杆)的后端呈叉形,并支持一个铰链螺栓,铰链螺栓中心有一个横孔,通向摆动盘槽沟里的旋转环的冲击杆嵌在模孔里,通过冲击杆作用在传动件上的力主要由叉头接受,因此与使用球头一样,同样产生冲击杆沿径向自球头处向延伸出一凸肩阻止切向运动的问题。从该文件中没有提到如何解决这些问题。
因为润滑剂不能或者只能在很小的范围内进入冲击杆和铰链螺栓的导油腔,因此这里也有润滑问题。另外,铰链螺栓必须比冲击杆更准确地确定尺寸,因此小冲击钻确定尺寸时就可能首先出现困难。
本发明的任务就是,为这类型的冲击钻制造一种传动件防转安全装置,其结构简单、易于装配,不出现润滑问题且能防止脱落。
根据本发明,上述任务的解决方案如下,使冲击杆的凸肩位于两根成一定间距且平行排列的销钉之间,销钉的一端固定在传动件的后壁内,另一端固定在传动件后部凸台的尾壁内。
下面对照附图说明本发明的一个实施例。其中:
图1表示传动件和由其带动的摆动体的局部视图,
图2表示传动件的俯视图,
图3表示图2中A-B截面的剖视图。
正如图1所示,呈空心活塞形状的传动件1将使沿轴向自由移动的冲击体2通过气垫做往复运动,在传动件的后部有一个凸台3,在这个凸台内装有轴承套4(环)。冲击杆6上的球状球头5位于轴承套4内,冲击杆6沿径向延伸并固定在一个滚珠轴承8的外环上,该轴承和中间轴10的轴线成α交角,中间轴(10)上有轴套12,而该轴套外部则套着滚珠轴承8的倾斜安装的内环11,中间轴(10)可驱动轴套转动。
冲击杆球头5上的突出的凸肩13位于两个成一定间距平行排列的紧固销钉14、15之间,该销钉的一端固定在传动件的后壁16内,另一端固定在传动件后部凸台的尾壁17内。
两个紧固销钉14和15穿在凸台3的尾壁17上的通孔18,19内并且向前压紧,直至其伸入传动件的壁上的盲孔18′,19′内(参见图2和图3)。
由于冲击杆6的旋转方向上作用有分力并且球头5的中心产生了位移,所以在传动件上作用有扭矩,而本发明中的防转安全装置可以防止传动件沿圆周方向的转动。
