Description

用于IV型气瓶内胆成型的摩擦旋熔机
技术领域
本发明涉及一种储氢容器成型设备技术领域，具体是用于IV型气瓶内胆成型的摩擦旋熔机。
背景技术
目前主流的车载储氢技术——高压气态储氢，其容器按种类可分为：纯钢制金属瓶(I型)、钢制内胆纤维缠绕瓶(II型)、铝内胆纤维缠绕瓶(III型)和塑料内胆纤维缠绕瓶(IV型)4种，IV型瓶具有长寿命、轻量化、生产效能高、降成本潜力大等优势。随着氢能产业热潮兴起，市场对IV型储氢瓶的需求越来越迫切。IV型瓶内胆是通过注塑加工成型的，由于工艺的原因无法一次注塑成型得到气瓶内胆，因此可以注塑成两半后再通过焊接等方式合成整体，而内胆间的可靠连接是其加工的技术难点。现有技术中内胆主要通过热板焊、激光焊进行连接，内衬损耗较大、加工质量难以保证。而通过摩擦旋熔的方式能够快速地将内胆连接到一起，但现有的旋熔机精度不能达到IV型气瓶的密封要求。
因此，有必要提供用于IV型气瓶内胆成型的摩擦旋熔机，以解决上述背景技术中提出的问题。
发明内容
为实现上述目的，本发明提供如下技术方案：用于IV型气瓶内胆成型的摩擦旋熔机，包括支架，所述支架下方设有多个圆周分布的夹台，所述支架一侧设有升降台，所述升降台上部设有伺服驱动的升降架，所述升降架对应夹台分布位置的正上方设有夹持臂，所述夹持臂上方的升降架中固定有能够驱动其旋转的电机；
所述升降台下端固定有稳定套环组件，所述稳定套环组件套设在固定于夹台的下内胆与夹持臂的上内胆间的间隙外围。
进一步的，作为优选，所述稳定套环组件包括套环壳体，所述套环壳体为两个半圆环组成的套环，其内壁中可转动地设有多根滚柱。
进一步的，作为优选，两个所述套环壳体的两个接触面中各分别对应地设有导磁块和电磁铁，且其二者间设有嵌入套环壳体内的分离弹簧；
且，所述分离弹簧在自然状态下使得两个套环壳体分离，所述电磁铁在通电时能够吸附对应的导磁块从而使两个套环壳体贴合成完整的环形。
进一步的，作为优选，每根所述滚柱侧面固定有高频线圈，且所述滚柱内部为金属材质，所述高频线圈通电能够加热滚柱。
进一步的，作为优选，所述滚柱的上下端各通过滑块与套环壳体可滑动地连接，所述滑块可滑动地连接到套环壳体上下面开始的滑槽中，所述滚柱的中心转轴通过腰形槽铰接到滑块中。
进一步的，作为优选，所述滑块中固定有推杆，所述推杆与套环壳体可滑动地连接且贯穿到其外壁外，所述推杆外壁还套设有支撑弹簧，所述支撑弹簧的一端固定在套环壳体中；
且，所述支撑弹簧在自然状态下使得滚柱保持竖直且凸出到套环壳体内壁内。
进一步的，作为优选，所述推杆末端固定有距离传感器，所述距离传感器能够测量其与套环壳体外壁的距离。
进一步的，作为优选，同一滚柱对应的上下两根推杆的中部间通过支撑板连接到一起，所述支撑板的上下端各通过铰接套上的腰形槽与其二者铰接。
进一步的，作为优选，所述支撑板与套环壳体的外壁间的腔体内设有气囊，所述气囊的气压由固定在套环壳体外的气泵控制。
进一步的，作为优选，所述滚柱外壁涂有润滑涂层。
与现有技术相比，本发明的有益效果是：
本发明中，当套环壳体夹紧下内胆与上内胆的间隙时，高频线圈加热滚柱能够通过热传递而加热下内胆与上内胆，从而使其达到恒定温度，避免由于热胀冷缩影响其二者间隙的初始大小。
本发明中，当套环壳体夹紧下内胆与上内胆，滚柱受到挤压向外移动，而当下内胆与上内胆存在错位时，滚柱会发生倾斜，从而使其上下两根推杆伸出到套环壳体外的距离不相同而发生错位，且该错位的大小和方向由距离传感器记录而能够通过数据显示出下内胆与上内胆错位的大小和方向，以方便进行准确地修正。
本发明中，通过气泵对气囊充气，使其产生对支撑板的推力，推动滚柱对下内胆与上内胆进行夹持，能够使其二者的转动更稳定。

具体实施方式
请参阅图1，本发明实施例中，用于IV型气瓶内胆成型的摩擦旋熔机，包括支架1，所述支架1下方设有多个圆周分布的夹台2，所述支架1一侧设有升降台3，所述升降台3上部设有伺服驱动的升降架4，所述升降架4对应夹台2分布位置的正上方设有夹持臂5，所述夹持臂5上方的升降架4中固定有能够驱动其旋转的电机6；
所述升降台3下端固定有稳定套环组件7，所述稳定套环组件7套设在固定于夹台2的下内胆9与夹持臂5的上内胆8间的间隙外围。
请参阅图2，本实施例中，所述稳定套环组件7包括套环壳体71，所述套环壳体71为两个半圆环组成的套环，其内壁中可转动地设有多根滚柱72。
本实施例中，两个所述套环壳体71的两个接触面中各分别对应地设有导磁块73和电磁铁74，且其二者间设有嵌入套环壳体71内的分离弹簧75；
且，所述分离弹簧75在自然状态下使得两个套环壳体71分离，所述电磁铁74在通电时能够吸附对应的导磁块73从而使两个套环壳体71贴合成完整的环形；
也就是说，当套环壳体71套设入下内胆9与上内胆8的间隙外围时，电磁铁74通电能够使套环壳体71将其夹紧。
本实施例中，每根所述滚柱72侧面固定有高频线圈721，且所述滚柱72内部为金属材质，所述高频线圈721通电能够加热滚柱72；
当套环壳体71夹紧下内胆9与上内胆8的间隙时，高频线圈721加热滚柱72能够通过热传递而加热下内胆9与上内胆8，从而使其达到恒定温度，避免由于热胀冷缩影响其二者间隙的初始大小。
请参阅图3，本实施例中，所述滚柱72的上下端各通过滑块76与套环壳体71可滑动地连接，所述滑块76可滑动地连接到套环壳体71上下面开始的滑槽中，所述滚柱72的中心转轴通过腰形槽铰接到滑块76中，从而使得滚柱72能够在竖直方向转动一定角度。
本实施例中，所述滑块76中固定有推杆77，所述推杆77与套环壳体71可滑动地连接且贯穿到其外壁外，所述推杆77外壁还套设有支撑弹簧78，所述支撑弹簧78的一端固定在套环壳体71中；
且，所述支撑弹簧78在自然状态下使得滚柱72保持竖直且凸出到套环壳体71内壁内。
本实施例中，所述推杆77末端固定有距离传感器711，所述距离传感器711能够测量其与套环壳体71外壁的距离；
也就是说，当套环壳体71夹紧下内胆9与上内胆8，滚柱72受到挤压向外移动，而当下内胆9与上内胆8存在错位时，滚柱72会发生倾斜，从而使其上下两根推杆77伸出到套环壳体71外的距离不相同而发生错位，且该错位的大小和方向由距离传感器711记录而能够通过数据显示出下内胆9与上内胆8错位的大小和方向，以方便进行准确地修正。
本实施例中，同一滚柱72对应的上下两根推杆77的中部间通过支撑板79连接到一起，所述支撑板79的上下端各通过铰接套710上的腰形槽与其二者铰接。
本实施例中，所述支撑板79与套环壳体71的外壁间的腔体内设有气囊712，所述气囊712的气压由固定在套环壳体71外的气泵10控制；
也就是说，通过调整气囊712的气压，使其产生对支撑板79的推力，从而推动滚柱72对下内胆9与上内胆8进行夹持，能够使其二者的转动更稳定。
本实施例中，所述滚柱72外壁涂有润滑涂层，优选为聚四氟乙烯材料，使滚柱72与下内胆9和上内胆8间转动时减少摩擦阻力。
具体实施时，将下内胆9固定到夹台2中心，将上内胆8固定到夹持臂5中，下降升降台3使下内胆9与上内胆8合拢，同时稳定套环组件7套在下内胆9与上内胆8的连接处；
电磁铁74通电吸附对应的导磁块73从而使两个套环壳体71贴合成完整的环形，同时，滚柱72受到挤压向外移动，而当下内胆9与上内胆8存在错位时，滚柱72会发生倾斜，且错位的大小和方向由距离传感器711记录；
调整夹台2和夹持臂5以修正下内胆9与上内胆8的位置后，高频线圈721加热滚柱72，电机6驱动夹持臂5低速转动以预加热下内胆9与上内胆8的连接处；
电机6停转，调整升降架4使夹持臂5下的上内胆8对下内胆9施加一个预定的压力，并通过气泵10对气囊712充气，使其产生对支撑板79的推力，从而推动滚柱72对下内胆9与上内胆8进行夹持，能够使其二者的转动更稳定；
电机6驱动上内胆8高速转动使上内胆8与下内胆9的接触面摩擦融合。
以上所述的，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内。
