Abstract

本发明属于汽车零部件生产制作领域,具体涉及一种用于夹装汽车后地板总成的夹具支撑台。本发明包括用于安置夹具的安装部以及用于托撑安装部的支撑底座,所述安装部可转动的安装于支撑底座上。由于整个夹具台可转动,纵然夹具相应的占用了较大的横向空间,工作人员仍能在一个或多个固定位置操作电焊机并点焊到需点焊工件的所有焊接部位,减少了工作人员的移动频率;通过将传统的夹具台不动而工作人员环绕其工作的操作方式变更为工作人员不动而夹具台实现相应转动操作,从而极大的降低了工作人员的劳动强度,最终可实现高效率生产。

Description

一种夹具支撑台
技术领域
本发明属于汽车零部件生产制作领域,具体涉及一种用于夹装汽车后地板总成的夹具的支撑台。
背景技术
目前,汽车后地板总成的点焊装配工序中,均需先将其夹持于汽车后地板总成夹具上以固定其相对位置,再由人工操作电焊机对其需焊接部位进行点焊操作。在实际操作中,由于汽车后地板总成都为平卧并夹持固接于其夹具上的,致使其夹具相应的占用了较大的横向空间,工作人员难以在某一固定位置操作电焊机并点焊到汽车后地板总成的所有焊接部位,因此必须在焊接时以其夹具为圆心绕其一周实现焊接,费时费力,极大的增加了工作人员的劳动强度,同时造成工作效率低下。
发明内容
本发明的目的是提供一种结构简单的夹具支撑台,可有效降低工作人员的劳动强度,极大的提升其工作效率。
为实现上述目的,本发明采用了以下技术方案:一种夹具支撑台,包括用于安置夹具的安装部以及用于托撑安装部的支撑底座,所述安装部可转动的安装于支撑底座上。
本发明的有益效果在于:由于整个夹具台可转动,纵然夹具相应的占用了较大的横向空间,工作人员仍能在一个或多个固定位置操作电焊机并点焊到需点焊工件的所有焊接部位,减少了工作人员的移动频率;通过将传统的夹具台不动而工作人员环绕其工作的操作方式变更为工作人员不动而夹具台实现相应转动操作,从而极大的降低了工作人员的劳动强度,最终可实现高效率生产。
附图说明
图1为本发明安置夹具a后的使用状态结构示意图;
图2-3为本发明的分解结构示意图;
图4为本发明的分解结构正面视图。
具体实施方式
一种夹具支撑台,包括用于安置夹具的安装部10以及用于托撑安装部10的支撑底座20,所述安装部10可转动的安装于支撑底座20上,如图1-4所示。
作为本发明的进一步优选方案,为实现上述的可转动性能,所述夹具支撑台还包括旋转单元,所述旋转单元包括滚动体31以及用于引导滚动体31动作的保持架32,所述旋转单元夹设于安装部10与支撑底座20之间,所述安装部10、支撑底座20以及旋转单元三者构成推力轴承式构造;也就是说,由于实现安装部10相对支撑底座20可转动的方案为多种,本发明实现的即为在其两者结合部设置推力轴承构造,具体见图2-4所示,由于推力轴承本身即主要承受轴向力,当将其理念应用于本发明上时,将安装部10视为推力轴承的上圈,将支撑底座20视为推力轴承的下圈,其中构成旋转单元的各组件自然组成推力轴承的滚动体以及保持架部分,最终实现了本发明的可转动性能,其中本发明的滚动体优选为滚珠。
进一步的,所述安装部10和构成旋转单元的保持架32外形均呈圆盘状,所述支撑底座20包括用于与旋转单元配合的托盘21,为实现上述部件间的有效可靠配合,所述托盘21、安装部10和保持架32三者同轴设置且三者轴线处贯穿设置有用于限定旋转单元旋转轴心的定心轴40,所述定心轴40的上侧轴端挂置于保持架32的轴心处。实际操作时,如图1所示,当工作人员转动夹具a,与之固接的安装部10即可带动旋转单元绕定心轴40产生运动,由于定心轴40本身具有重量,将其一端挂置在可转动的保持架32的轴心处,而另一端贯穿并插入相对静止的托盘21中,即可确保其定心可靠,最终保证其有效的实现具体功能。
更进一步的,为具体实现定心轴40的挂设结构,所述夹具支撑台包括挡圈50,如图4所示,所述挡圈50夹设于安装部10与构成旋转单元的保持架32间且其外径尺寸大于保持架32的轴心孔内径,所述定心轴40外形呈阶梯轴状且其大口径段与支撑底座20构成配合关系,所述定心轴40小端端口部穿过保持架32的轴心孔且与挡圈50间固接,从而通过挡圈50与定心轴40小端构成的台肩部自然挂靠于保持架32的轴心孔的一侧孔端处。实际工作中,可将安装部10或保持架32的相应与挡圈50配合处设置与其外形吻合的凹槽,以保证其整体结构的紧凑性。
更进一步的,为便于本发明移动,如图2-4所示,所述支撑底座20还包括用于支撑托盘21并使其脱离地面的支撑架22,所述支撑架22外形呈“十”字状且其“十”字状支撑架22各尖部底端均设置辊轮部221,所述支撑架22上端与托盘21的一侧盘面固接。
考虑到现有夹具其机械化较多,不可避免存在与外界设备间的线路连接问题,因此,如图2-4所示,所述夹具支撑台由上至下开设有用于线路穿过的通孔,所述通孔轴线与定心轴40轴线重合且通孔内径尺寸小于定心轴40外径尺寸设置,这样,实际应用中直接将线路通过通孔连接外界与需连接的夹具a间,由于本发明实际上是以定心轴40为中心来转动的,也就是说可确保位于通孔内的线路不至于因外界转动而导致扭转和线路错乱问题,从而保证整台夹具的可靠正常运行。
