Description

圆筒状工件加工用夹具
技术领域
本发明涉及一种夹具。具体说,是加工圆筒状工件时用来对圆筒装工件进行固定的夹具。
背景技术
目前在机械加工领域,加工圆筒状工件时大都是采用三爪卡盘来对圆筒状工件进行固定。虽然采用三爪卡盘可以实现圆筒状工件的固定,但由于三爪卡盘只有其三个爪与圆筒状工件相接触,圆筒状工件只有三个点受力,受力很不均匀,甚至会导致圆筒状工件变形。因此,采用三爪卡盘对圆筒状工件进行固定,难以保证被加工工件的质量,使得加工出的工件质量较差。
发明内容
本发明要解决的问题是提供一种圆筒状工件加工用夹具。采用这种夹具来对圆筒状工件进行固定,能保证被加工工件的质量,使得加工出的工件质量较高。
本发明要解决的上述问题由以下技术方案实现:
本发明的圆筒状工件加工用夹具特点是包括底座和上大下小的圆锥形顶柱。所述底座为圆筒状,其下端有筒底。底座的四周均布有圆弧形块,由所述圆弧形块拼接成一个横截面为矩形的圆环。所述圆弧形块的内圆一侧均有径向伸缩头,与所述径向伸缩头对应的底座相应位置处均有径向滑孔,所述径向伸缩头呈滑动状伸入径向滑孔内,且径向伸缩头里端均为上大下小的圆锥形面。所述圆弧形块的下侧面中间与所述底座的筒底邻近中间之间均有拉簧,在所有拉簧非拉伸状态下,由所有径向伸缩头里端的圆锥形面组成一个与圆锥形顶柱相配的上大下小的圆锥形孔。
所述圆弧形块的下侧面上均有圆弧形下凸台,以便在圆弧形块下侧面与相应径向伸缩头的的下侧面间形成限位台阶。
采取上述方案,具有以下优点:
由上述方案可以看出,由于本发明由底座、上大下小的圆锥形顶柱、底座四周的圆弧形块、圆弧形块内圆一侧的径向伸缩头、与所述径向伸缩头对应的底座相应位置处的径向滑孔组成,所述径向伸缩头呈滑动状伸入径向滑孔内,且径向伸缩头里端均为上大下小的圆锥形面。所述圆弧形块的下侧面中间与所述底座的筒底邻近中间之间均有拉簧,在所有拉簧非拉伸状态下,由所有径向伸缩头里端的圆锥形面组成一个与圆锥形顶柱相配的上大下小的圆锥形孔。工作时,给圆锥形顶柱一个向下的推力,可推动径向伸缩头沿径向向外伸出,直至使径向伸缩头外端的圆弧形块的外侧面紧紧顶在被加工圆筒状工件的内侧面上。与背景技术相比,变传统被加工圆筒状工件由三点受力为多面受力,使得受力均匀,从而避免了圆筒状工件变形情况的发生。因此,采用本发明对圆筒状工件进行固定,能确保被加工工件的质量,使得加工出的工件质量较高。
附图说明
图1是本发明的圆筒状工件加工用夹具结构示意图;
图2是去掉圆锥形顶柱的图1的俯视示意图;
图3是本发明的圆筒状工件加工用夹具使用状态示意图。
具体实施方式
如图1和图2所示,本发明的圆筒状工件加工用夹具包括底座2和圆锥形顶柱3。所述底座2为圆筒状,其下端加工有筒底。所述圆锥形顶柱3为上大下小的圆锥形。所述底座2的四周均布有四块圆弧形块5,由四块所述圆弧形块5拼接成一个横截面为矩形的圆环。所述圆弧形块5的内圆一侧均加工有径向伸缩头4,与所述径向伸缩头4对应的底座2相应位置处均加工有径向滑孔,所述径向伸缩头4呈滑动状伸入径向滑孔内,且径向伸缩头4里端均为上大下小的圆锥形面。在所述圆弧形块5的下侧面中间与所述底座2的筒底邻近中间之间均设置有拉簧6,拉簧6两端分别连接在圆弧形块5的下侧面中间和底座2的筒底邻近中间处。在所有拉簧6非拉伸状态下,由所有径向伸缩头4里端的圆锥形面组成一个与圆锥形顶柱3相配的上大下小的圆锥形孔。
其中,所述圆弧形块5的下侧面上均加工有圆弧形下凸台,以便在圆弧形块5下侧面与相应径向伸缩头4的下侧面间形成限位台阶7,以用于对径向伸缩头4缩回时进行限位。
如图3所示,利用本发明对圆筒状工件1进行固定时,首先在圆锥形顶柱3上方给圆锥形顶柱3一个向下的压力,由圆锥形顶柱3的锥形面对所述径向伸缩头4里端的锥形面一个压力,使四个径向伸缩头4及其外端的圆弧形块5一起向外伸出,直至使四个圆弧形块5同时顶住被加工圆筒状工件1的内圆,从而实现了对圆筒状工件1的固定。变传统被加工圆筒状工件1由三点受力为多面受力,使得受力均匀,从而避免了圆筒状工件1变形情况的发生,确保了被加工工件的质量。
