Description

一种扩孔机
技术领域
本发明涉及汽车零部件生产研究领域中的一种扩孔机，特别是一种用于弯曲件弯曲前塞入特定胶条的扩孔机。
背景技术
在生产汽车零部件中，有部分零件需要折弯的，然而，由于该零件的折弯一端为中空腔，在折弯过程中，尺寸偏差较大。弯曲出来的产品尺寸不稳定，造成后续产品的不合格率升高，而通过塞入特定胶条的方法很好的解决了这个问题。但是，特定胶条不能直接从中空腔的进口端插入，需要对中空腔的进口端进行处理后才能。现有的操作方式为，操作人员一手把持扩孔治具，操作人员的另一只手拿着零件，用力挤压后对中空腔的开口端进行扩孔。由于人工操作，扩孔的质量不稳定，导致需要二次或者三次扩孔才能将特定胶条塞入中空腔中，产生效率低下，长时间工作后，操作员容易累，且劳动强度大。因此，亟需一种用于弯曲件弯曲前塞入特定胶条的设备。
发明内容
本发明的目的，在于提供一种扩孔机，其将待弯曲产品一端的孔进行扩孔工艺后，便于将特定胶条塞入，以便于后续弯曲。
本发明解决其技术问题的解决方案是：一种扩孔机，包括机座，所述机座上布置有沿水平方向依次布置的扩孔驱动源、夹具组以及挡板，所述扩孔驱动源的动作端上安装有扩孔头，所述扩孔头的末端朝向夹具组，所述夹具组包括沿水平方向依次布置的若干个第一夹具，所述第一夹具包括下夹具、上夹具以及驱使上夹具运动的夹具驱动源，所述下夹具的上端面布置有下夹腔，所述上夹具的下端面布置有上夹腔。
作为上述技术方案的进一步改进，所述扩孔头包括连接扩孔驱动源的连接杆以及锥形头，所述锥形头的一端固定在连接杆上，锥形头的另一端为呈锥形的凸起块，所述凸起块的前端为导向弧面。
作为上述技术方案的进一步改进，所述凸起块从其末端开始内凹成一个仿形槽。
作为上述技术方案的进一步改进，所述下夹腔的外表面布置有缓冲胶层，所述上夹腔的外表面布置有缓冲胶层。
作为上述技术方案的进一步改进，所述上夹具的一端铰接在机座上，所述夹具驱动源驱使上夹具绕着铰接轴旋转后，上夹具扣合在下夹具上。
作为上述技术方案的进一步改进，所述机座上布置有导向座，所述导向座上布置有导向滑槽，所述扩孔头安装在所述导向槽内后沿着导向槽往复移动。
作为上述技术方案的进一步改进，所述第一夹具的数量为3个或者4个。
本发明的有益效果是：本发明通过将产品水平放置到第一夹具上后，产品的一端与挡板压触，产品的另一端对着扩孔头，扩孔驱动源驱使扩孔头插入到产品的中空端后，通过扩孔头逐渐增大的外形尺寸对产品进行扩孔，从而轻而易举地就能塞入特定胶条。本发明实现该产品的半自动扩孔，提高生产效率，降低操作人员的劳动强度。
