Abstract
本发明关于一种拉出空心铆钉的工具,特别是自钻孔带有墩粗销的那一种。本工具被设计用于连接在手工具(1)的驱动轴(2)上,它包括带通孔(9)的嘴部(8),空心铆钉插入嘴部后当驱动轴(2)向一个方向旋转时会被带着转,当驱动轴(2)向相反方向旋转时,拉出装置(10、12)把铆钉的墩粗销拉出。
Description
本发明关于一种工具,用于拉出有墩粗销的空心铆钉又能用来占孔和拧螺钉。本发明也有关一种用于本发明工具的自占孔空心铆钉。本发明的工具能用于铆传统的波普空心铆钉,但最好是使用波普空心铆钉中的自占孔空心铆钉,这铆钉连同它的墩粗销一起插进工具中,通过拉去铆钉的墩粗销,占出铆钉孔和铆合,撕去墩粗销并从连接墩粗销的铆钉上拉出留下的销。所有这些工作可以被本发明的工具在一道工序中做好而不需要换工具。
当用所谓波普铆钉进行铆合时,首先要在工件上用占机占一个孔,然后换上工具进行铆合,如用手动或者液压或气压操作的铆机。这种工作很费时,因为占孔操作首先是用机器完成的,然后换上铆合用的工具,用手动或者重而复杂的铆合工具。
因此本发明的目的是提供一种小型轻便灵巧的工具,它能使用自占孔铆钉,并能铆合,这个工具还能撕去和抽出铆钉销。本发明的另一目的是做出一种工具,它可以使用占头,所以这个工具能用来占孔,此外还能拧螺钉。本发明进一步的目的是提供一种自占孔的空心铆钉,它造价便宜,还能形成一个不漏气的套。这些目的由本发明下面要提到的特征来实现的。
现在用附图中的图示例对本发明作详述。其中,

图2是按照本发明铆钉的第一改型的侧视图,部分剖开,
图3是图2中的铆钉从图2左面看过去的侧视图,

图1所示的工具被设计用于最好是电动拧螺钉机1上,该机可反转,以作左,右旋运作。然而,该机可以是由液压或气压操作的。在拧螺钉机1的驱动轴2上有一个内套3,它是拧在驱动轴2上的,最好是通过螺纹和驱动轴2连接在一起不能作相对转动,这可用锁紧螺钉4来达到。内套3被围绕在外套5的中间,外套5远离驱动轴的端部有一个前端套6可拆卸地装在外套上,并通过锁钉7不能转动地连接在外套5上。在端套6的前部拧有一个可更换的嘴部8,嘴部8有一个多边形截面的孔9,这在下面还要详述。端套6是空心的,这空心部分最好是正方形截面。拉出件10伸入此空心部分的是外形呈正方形的滑动部分10a。拉出件10的另一端用外螺纹11连接着内套的内螺纹。在拉出件10和内套3上的螺纹是左手螺纹,下面还要详细说明。拉出件10的前部形成退拔,支承着两个锥形拉出夹头12,两夹头12有一个通道用来夹持铆钉销。在两拉出夹头12里边是一个接收件13,它被置于拉出件的空心中,该接收件支承在两拉出夹头12上,并有一根弹簧14使它顶紧在两夹头12上,弹簧14用压板15和螺钉16连接在拉出件10的后部。
使用此工具时,带有墩粗销的铆钉通过嘴部8的孔9被放入,这样,铆钉的予成型的法兰就抵住嘴部8。铆钉最好带有占头尖,但这不是必需的,以及有数条边的墩粗销,以适合嘴部8的通道9,并由此伸出。如果铆钉是带有自占孔尖的话,驱动轴2就置于右旋,整个工具就在此方向旋转。嘴部8也可以在外部形成凿尖以配合铆钉套颈圈部的十字槽,这种颈圈部如图9所示,以驱动铆钉套旋转。由于拉出件10和内套3的螺纹11是左手螺纹,拉出件10被拉进内套3中,并因为拉出件的滑动部分10a是正方形的,它伸入端套6的方孔中而防止拉出件的旋转。拉出件的退拔部分就夹住夹头12,使夹头12被夹住铆钉销并把它向内拉,外套5也被拉向后直至它顶住机器的外壳1。外壳5就不会转动了。另外,拉出件10能被进一步移进内套3中直至铆钉被压缩和拉去。此后,驱动轴2的旋转方向再度反转成右旋,操作者用手抓住外套5防止它旋转。拉出件10就再度移出,夹头12被接收件13压得分开而离开销。如果这个工具此时被朝向下方,销的其余部分就要掉出来,就能开始新的铆合操作。
因此,本发明的工具具有简单的结构,使得制造费用非常便宜,此外,使用可靠。如果这个工具被用来在机器上拧螺钉或其它工作,需要左旋操作,那么可以把外套5锁定在内套3上,这可以把锁紧螺钉4旋出几圈把这两个部分连在一起而不会相互旋转。当然,这个工具也可以被做成一个专用机器,用于铆钉的拉出和占孔,接着拉出自占孔的空心铆钉。
因此,在图2至图6中显示了按照本发明的空心铆钉,它包括一个带有颈圈部分22的铆钉套21。一个墩粗销23穿过铆钉套21的中心孔,销上有位于颈圈部分外面的旋转翼24,用来转动墩粗销23。墩粗销23的另一端从铆钉套21中伸出,带有一个放大的主体部分25,它的外径大约等于铆钉套21的套部分的外径。这放大的主体部分25和墩粗销23的其余部分是一体的,但在主体部分25上有一个薄弱部分26,它直接位于放大的主体部分下面,当铆钉铆紧后,主体部分可由此从墩粗销上被分离。在放大的主体部分25上做出一个槽27,用来收容一个可拆卸的切削插件28。切削插件28有切削刃29和置于其下的凹缺30,这可由图2和图3中清楚地看到。主体部分25最好形成有一个夹入件31,伸进槽27中和切削插件28的凹缺30配合,把切削插件固定在主体部分上。从图5和图6可清楚看到,但也显示于图2中的虚线,槽27的底部可以是屋顶形的,而此时的切削插件28的底和它相配合以便进一步把切削插件固定在主体部分上。这个可换的切削插件28的宽度比主体部分25的直径和铆钉套21的套部分的直径大些。
切削插件28的材料和铆钉套及墩粗销的材料不同,可以是占头钢的插件,或者是用粉末材料压成适当的形状。
图7至图10的空心铆钉也有一个可拆卸的切削插件28。然而,在此例中,销23并没有完全地通过铆钉套21,而铆钉套在此包围着墩粗销的放大的主体部分25,墩粗销在这里的直径比铆钉套的直径小。因此,这个铆钉是一种气密铆钉,可换的切削插件28在此处连接到这个铆钉套21的端部。切削插件的这个实施例和图2至图6中的实施例基本相同,虽然切削插件的底部有着不同的形状,由图7可清楚看到,在这里的槽27形成于铆钉套21的端部,和切削插件相符合地具有另外的形状。在这个例中墩粗销23是不旋转的,用来提供占孔的是这个铆钉套21,因此在套的颈圈部分22形成十字形槽32,如图9所示,套中可配置一个适当的旋转工具。
图11和图12中,显示了按照本发明空心铆钉的第三实施例,基本上相同于图2至图6所述的空心铆钉,不同之处是这里没有可换的切削插件,但是这里的墩粗销的放大的主体部分被一个涂有粉末材料具有切削性能的切削刃29所代替。
图13和图14中显示了按照本发明空心铆钉的第四改型,它基本上和图7至图10的改型相符,不同之处是这里没有可拆卸的切削插件,但这里在铆钉套的端部形成着涂有切削性粉末材料的切削刃29。
所有显示于图中的普通空心铆钉的切削装置是用不同于铆钉套和墩粗销的材料制造的。切削装置可以是可换的切削插件,它用占头钢或粉末材料造成,例如碳化硅,这可以用来压成切削插件或者涂在铆钉或墩粗销端上。也可以不用上述方法,而是把粉末材料直接涂在铆钉套上,而这铆钉套上形成着切削刃,但也可以在某种场合把切削粉末材料直接涂在铆钉的基本上平的端面上。如何处置切削粉末材料,是由铆钉要用于何种材料而定。由于用了和铆钉套和墩粗销不同材料的切削装置以产生切削效果,这就可以采用轻金属来做铆钉套和墩粗销,例如铝,如果要从这种金属直接获得切削效果,那就不可能用这种金属做铆钉套和墩粗销了。
在附图中显示出在墩粗销上有旋转翼,同时在铆钉套的颈圈部分有一个十字形槽,以便铆钉为了占孔而能转动。在这些例子中所使用的工具必须备有相应的啮合装置通过旋转翼或十字形槽以转动铆钉和/或墩粗销。然而,这些为旋转而设的装置也可以采用各种其它的不同方法,这些都是内行熟手所知的。
