Description

一种夹持顶紧机构 技术领域
本发明涉及非标自动化设备领域，特别涉及一种夹持顶紧机构。
背景技术
在非标自动化流水线上往往需要用到多种夹持机构，在某些工位中需要对工件夹持的同时给予顶紧以保证工件的稳定，在现有技术中往往通过两个夹具来实现，即在待夹紧工件的工位处安装夹持机构与顶紧机构，然而采用这种方式往往导致整条流水线系统过于繁重，也导致了拆装过程的繁琐、耗时，有鉴于此，实有必要开发一种夹持工件的同时能够顶紧的夹持顶紧机构，用以解决上述问题。
发明内容
针对现有技术中存在的不足之处，本发明的目的是提供一种夹持顶紧机构，其结构简单，在夹紧工件的同时还能顶紧工件，大大简化了机构的复杂性，同时还降低了机构的体积，提高了拆装、调试效率及便捷性。
为了实现根据本发明的上述目的和其他优点，提供了一种夹持顶紧机构，包括：
夹紧组件；以及
用于驱动夹紧组件的驱动器，
其中，夹紧组件包括基座、压紧板、以及顶紧板，夹紧组件开设有垂直相交的纵向安装通孔与横向安装通孔，压紧板及顶紧板分别设于纵向安装通孔及横向安装通孔中，压紧板及顶紧板可在驱动器的驱动下分别沿竖直方向滑移及沿水平方向滑移。
优选的是，压紧板包括：
横向延伸的压紧板主体；以及
纵向延伸的牵引部，其与压紧板主体相固接，
其中，牵引部上开设有与竖直方向呈一定夹角的导引槽，导引槽的贯穿 方向与顶紧板的运动方向相垂直，牵引部的底部开设有与驱动器的动力输出端相配接的卡接槽。
优选的是，顶紧板上开设有配合通孔，配合通孔中设有导引杆，导引杆在水平面内直线延伸且其延伸方向与导引槽的贯穿方向相一致。
优选的是，配合通孔在顶紧板运动方向上的孔径尺寸大于纵向安装通孔在顶紧板运动方向上的孔径尺寸，配合通孔在导引杆延伸方向上的孔径尺寸不小于纵向安装通孔在导引杆延伸方向上的孔径尺寸。
优选的是，当顶紧板设于横向安装通孔中时，压紧板能够从上至下依次插入纵向安装通孔及配合通孔中，同时导引杆插入到导引槽中。
优选的是，导引槽与竖直方向的夹角为30°～45°。
优选的是，导引槽在其端部设有至少一个沿竖直方向延伸的锁止槽，所述锁止槽与导引槽相连通。
优选的是，压紧板主体与顶紧板相互平行设置且相隔一定的距离已形成两者之间的夹持空间。
优选的是，顶紧板上与工件相接触的一端设有沿其长度延伸方向呈逐渐缩小之势的接触部。
本发明与现有技术相比，其有益效果是：由于压紧板及顶紧板可在驱动器的驱动下分别沿竖直方向滑移及沿水平方向滑移，从而可使得驱动器仅需一个方向的动作就能在压紧工件的同时将工件沿水平方向顶紧，简化了机构的结构复杂性，实现了两个方向的夹持定位功能，节省了安装空间，降低了反复拆装过程中的繁琐工序。

下面结合附图对本发明做进一步的详细说明，本发明的前述和其它目的、特征、方面和优点将变得更加明显，以令本领域技术人员参照说明书文字能够据以实施。在附图中，为清晰起见，可对形状和尺寸进行放大，并将在所有图中使用相同的附图标记来指示相同或相似的部件。在说明书中，诸如“前部”、“后部”、“上部”、“下部”、“顶部”和“底部”及其衍生词的相对术语应当被解释为是指如然后所述的或如在被讨论的附图中所示出的取向。这些相对术语是为了说明方便起见并且通常并不旨在需要具体取向。涉及附接、联接等的术语(例如，“连接”和“附接”)是指这些结构通过中间结构彼此直接或间接固定或附接的关系、以及可动或刚性附接或关系，除非以其他方式明确地说明。
参照图1，夹持顶紧机构包括：驱动器1及夹紧组件2，其中，驱动器1用于驱动夹紧组件夹紧，夹紧组件包括基座21、压紧板22以及顶紧板23，夹紧组件开设有垂直相交的纵向安装通孔211与横向安装通孔212，压紧板22及顶紧板23分别设于纵向安装通孔211及横向安装通孔212中，压紧板22及顶紧板23可在驱动器1的驱动下分别沿竖直方向滑移及沿水平方向滑移，从而可使得驱动器1仅需一个方向的动作就能在压紧工件的同时将工件沿水平方向顶紧，简化了机构的结构复杂性，实现了两个方向的夹持定位功能，节省了安装空间，降低了反复拆装过程中的繁琐工序。
再次参照图1，压紧板22包括：
横向延伸的压紧板主体221；以及
纵向延伸的牵引部222，其与压紧板主体221相固接，
其中，牵引部222上开设有与竖直方向呈一定夹角的导引槽2221，导引槽2221的贯穿方向与顶紧板23的运动方向相垂直，牵引部221的底部开设有与驱动器1的动力输出端12相配接的卡接槽222。在优选的实施方式中，导引槽2221沿前后方向贯穿牵引部222。
参照图1，顶紧板23上开设有配合通孔232，配合通孔232中设有导引 杆2321，导引杆2321在水平面内直线延伸且其延伸方向与导引槽2221的贯穿方向相一致。在优选的实施方式中，导引槽2221沿前后方向贯穿牵引部222，导引杆2321在水平面内直线延伸且其延伸方向亦为前后方向。
参照图1及图4，配合通孔232在顶紧板23运动方向上的孔径尺寸大于纵向安装通孔211在顶紧板23运动方向上的孔径尺寸，配合通孔232在导引杆2321延伸方向上的孔径尺寸不小于纵向安装通孔211在导引杆(2321)延伸方向上的孔径尺寸。在一实施方式中，配合通孔232在左右方向上的孔径尺寸大于安装通孔211在左右方向上的孔径尺寸，配合通孔232在前后方向上的孔径尺寸与纵向安装通孔211在前后方向上的孔径尺寸相同。在优选的实施方式中，配合通孔232在左右方向上的孔径尺寸为安装通孔211在左右方向上的孔径尺寸的1.5倍。
再次参照图1及图4，当顶紧板23设于横向安装通孔212中时，压紧板22能够从上至下依次插入纵向安装通孔211及配合通孔232中，同时导引杆2321插入到导引槽2221中。
进一步地，导引槽2221与竖直方向的夹角为30°～45°。在一实施方式中，导引槽2221与竖直方向的夹角为30°；在另一实施方式中，导引槽2221与竖直方向的夹角为35°；在另一实施方式中，导引槽2221与竖直方向的夹角为45°；
再次参照图1，导引槽2221在其端部设有至少一个沿竖直方向延伸的锁止槽，所述锁止槽与导引槽2221相连通。在优选的实施方式中，锁止槽设有两个，分别设于导引槽2221的上下两端。锁止槽的设置可以使得松开或夹紧状态保持稳定。
参照图2与图3以及图4与图5，压紧板主体221与顶紧板23相互平行设置且相隔一定的距离已形成两者之间的夹持空间。图2为根据本发明所述的夹持顶紧机构处于松开状态时的立体图，此时压紧板主体221与顶紧板23之间的距离大于待夹持工件的纵向尺寸，图3为根据本发明所述的夹持顶紧机构处于夹紧状态时的立体图，此时压紧板主体221与顶紧板23之间的距离略小于待夹持工件的纵向尺寸，而顶紧板23与工件相对端从横向将工件顶紧，从而能够将工件从纵向夹紧并从横向顶紧。
再次参照图1，顶紧板23上与工件相接触的一端设有沿其长度延伸方向呈逐渐缩小之势的接触部231。
这里说明的设备数量和处理规模是用来简化本发明的说明的。对本发明的应用、修改和变化对本领域的技术人员来说是显而易见的。
尽管本发明的实施方案已公开如上，但其并不仅限于说明书和实施方式中所列运用，它完全可以被适用于各种适合本发明的领域，对于熟悉本领域的人员而言，可容易地实现另外的修改，因此在不背离权利要求及等同范围所限定的一般概念下，本发明并不限于特定的细节和这里示出与描述的图例。
