具体实施方式
参见图1 ，本发明的一种PI管切断机，包括工作台2和用于卡紧工件1并带动工件1旋转的夹料机构3，所述工作台2上还设有第一Y轴滑轨21和底座气缸22，所述第一Y轴滑轨21上滑动安装有底座4，所述底座4上设有X轴导槽41，所述X轴导槽41内滑动安装有至少一组刀架底座5，所述刀架底座5上设有Y轴电动滑台51，所述Y轴电动滑台51上滑动安装有刀架6，所述刀架6上安装有刀片7。
进一步参见图2 ，所述刀架6包括刀架本体61、滑动安装在Y轴电动滑台51上的底板62和固定安装刀片7的夹具63，所述底板62上设有第一X轴滑轨621，第一X轴滑轨621上还开设有螺纹孔，所述刀架本体61底端设有与第一X轴滑轨621配合的第一滑槽611，所述刀架本体61底端位于第一滑槽611位置处还开设有长通孔612，所述刀架本体61通过一手旋螺钉64穿过长通孔612的方式紧固在第一X轴滑轨621的螺纹孔上；所述底板62前端伸出设有X轴千分尺622，所述刀架本体61前端对应地伸出设有一第一限位块613，所述X轴千分尺622的螺杆抵顶在第一限位块613上，在需要对刀片7进行左右位置微调时，先拧松手旋螺钉64，旋转X轴千分尺622，刀架本体61相对底板62滑动，拧紧手旋螺钉64锁定刀片7的位置并记录X轴千分尺622的刻度。
进一步参见图3，所述刀架本体61一侧竖直设有Z轴导轨614，所述夹具63设有与Z轴导轨614配合的第二滑槽631，所述夹具63还伸出设有一连接块632，所述连接块632上安装有Z轴千分尺633，所述刀架本体61前端对应地伸出设有第二限位块615以及与Z轴千分尺633平行的螺纹杆616，所述Z轴千分尺633的螺杆下端抵顶在第二限位块615上，所述连接块632套在螺纹杆616上，所述螺纹杆616位于连接块632上下两侧均设有紧固螺母，同样地，在需要微调刀片7的高低位置时，拧松连接块632两侧的紧固螺母，使连接块632得到释放，旋转Z轴千分尺633，使得连接块632在螺纹杆616上滑动，当刀片7到达预定位置时，拧紧连接块632两侧的紧固螺母并记录Z轴千分尺633上的刻度。
进一步参见图4和图5，所述夹料机构3包括安装在工作台2上的主轴组件31和安装在底座4前端的尾端夹紧组件32，所述主轴组件31包括主轴311和主轴电机312，所述主轴311沿其轴向套设有若干套管313且主轴311能够带动若干套管313同步旋转，套管313可沿主轴311的轴向相对移动，工件1套设在若干套管313上，相邻的两个套管313之间夹设有复位弹簧314，所述主轴311与相邻的两个套管313之间形成一伸缩槽315，所述伸缩槽315沿主轴311的轴向的长度随复位弹簧314的形变而变化，所述伸缩槽315内安装有密封圈316。
进一步参见图6，所述尾端夹紧组件32包括夹紧气缸321、第二X轴滑轨322以及滑动安装在第二X轴滑轨322上的夹紧支架323，所述夹紧支架323上设有夹头324，所述夹头324高度与主轴311高度一致，如图1所示，所述工作台2位于底座4前方还设有定位块8，当底座4在底座气缸22作动下抵顶在定位块8上时，所述夹头324处于主轴311的轴向延伸位置，所述夹头324在夹紧气缸321作动下可移动至主轴311一端，并沿主轴311的轴向挤压套管313，使得任意相邻的两个套管313之间的距离被缩短，同时复位弹簧314被压缩，伸缩槽315沿主轴311的轴向的长度变短并挤压密封圈316，使密封圈316被挤压变形导致其外径扩大，从而卡紧并限制工件1，密封圈316通过摩擦力能带动工件1同步旋转，并防止工件1沿主轴311的轴向滑动，从而使得主轴能够带动工件1一起旋转，保证工件1稳定不晃动，在工件1完成切割成段操作后，夹头324在夹紧气缸321作动下复位，相邻的两个套管313在复位弹簧314的弹力下松开密封圈316，密封圈316与工件1分离，可依次取出成段后的工件。
此外，当工件1需要同时切割成多段时，为了提高切割效率，套管313和刀片7可设置为多组，每段工件对应被至少一个密封圈316对应卡紧并被带动旋转，再采用相应数量的刀片7分段同时切割工件1，每段工件在旋转时不受其两端切割程度的影响，而传统的夹持方式是采用夹料设备直接夹紧工件1两端并带动其旋转，工件1是在来自其两端的旋转扭矩作用下旋转，若操作时用两组或两组以上的刀片同时分多段切割工件1，在切割过程未完全完成时，处于中间段的工件已经很难在其两端的旋转扭矩作用下正常旋转，造成切割后的工件尺寸精度非常低。
本切断机先将工件1套在主轴311上，移动底座4及夹紧支架323，夹头324夹紧工件1，主轴电机312驱动工件1旋转，刀片7在Y轴电动滑台51驱动下切割工件1，可将工件切割成多段，刀片7与工件1始终稳定地保持垂直稳定状态，使切割尺寸稳定，切割后的工件1边缘整齐无毛边。
以上所述，只是本发明的较佳实施方式而已，但本发明并不限于上述实施例，只要其以任何相同或相似手段达到本发明的技术效果，都应属于本发明的保护范围。
