Abstract

本发明涉及一种定心夹紧装置，包括壳体、内锥套、卡板、夹套和杠杆；所述壳体开有台阶孔，所述台阶孔底部中心开有通孔；所述壳体还开有水平贯通孔，中心开有通孔与所述水平贯通孔联通；所述内锥套固定在所述的台阶孔中，所述内锥套的内壁面为倒锥面；所述夹套设置在所述内锥套内；所述夹套下部具有内翻边，且从所述夹套的上端和下端交错开有多条轴向变形缝，使得夹套能够在径向上受到挤压而产生形变；所述杠杆可转动的设置在水平贯通孔中，杠杆一端与卡板联接，操作杠杆另一端能够带动夹套上下运动，当夹套向下运动时，会被内锥套挤压变形，从而夹紧夹套内的轴类零件。本发明能够快速的对轴类零件进行定位和夹紧，工件安装和操作方便。

Description

一种定心夹紧装置
技术领域
本发明属于工件紧固夹具领域，具体涉及一种定心抱紧装置，通过采用卡簧、锥形套和手柄的作用，实现对圆形工件的定心定位和夹紧。
背景技术
在车床夹具中，对于圆柱体工件的夹紧一般采用三爪卡盘，在铣床夹具中对圆柱体工件采用孔定位而后采用压板进行压紧。
发明内容
发明目的：需要提供一种对轴类零件的紧固和夹持的夹具。
发明技术方案：提供定心夹紧装置，包括壳体、内锥套、卡板、夹套和杠杆；
所述壳体开有台阶孔，所述台阶孔底部中心开有通孔；所述壳体还开有水平贯通孔，中心开有通孔与所述水平贯通孔联通；
所述内锥套固定在所述的台阶孔中，所述内锥套的内壁面为倒锥面；所述夹套设置在所述内锥套内，且夹套的外径大于所述倒锥面底部内径；
所述夹套下部具有内翻边，且从所述夹套的上端和下端交错开有多条轴向变形缝，使得夹套能够在径向上受到挤压而产生形变；
所述杠杆可转动的设置在水平贯通孔中，杠杆一端与卡板联接，夹套的翻边限位在所述卡板的卡槽内，杠杆另一端延伸到壳体外，操作杠杆另一端能够带动夹套上下运动，当夹套向下运动时，会被内锥套挤压变形，从而夹紧夹套内的轴类零件。
进一步的，壳体上还设有保护盖
进一步的，变形缝的端部开有应力分散孔。
进一步的，杠杆一端与卡板通过万向接头或球头节联接。
操作方法：
首先，将杠杆下压，杠杆另一端在卡板的作用下推动夹套上移，松开夹套，然后从上往下把轴类零件的一端插入夹套内，轴类零件在夹套内孔上定位，最后上拉杠杆，使夹套向下移动，对轴类零件实行夹紧。
技术效果：本发明能够快速的对轴类零件进行定位和夹紧，工件安装和操作方便。
附图说明
图1为本发明的夹紧状态示意图；
图2为夹套结构示意图；
图3为夹套与杠杆联接示意图；
其中：1-壳体、2-内锥套、3-夹套、3-1-变形缝、4-卡板、5-杠杆、6-万向接头或球头节、7-保护盖。
具体实施方式
提供一种定心夹紧装置，包括壳体、内锥套、卡板、夹套和杠杆；
所述壳体开有台阶孔，所述台阶孔底部中心开有通孔；所述壳体还开有水平贯通孔，中心开有通孔与所述水平贯通孔联通；
所述内锥套固定在所述的台阶孔中，所述内锥套的内壁面为倒锥面；所述夹套设置在所述内锥套内，且夹套的外径大于所述倒锥面底部内径；
所述夹套下部具有内翻边，且从所述夹套的上端和下端交错开有多条轴向变形缝，使得夹套能够在径向上受到挤压而产生形变；
所述杠杆可转动的设置在水平贯通孔中，杠杆一端与卡板联接，夹套的翻边限位在所述卡板的卡槽内，杠杆另一端延伸到壳体外，操作杠杆另一端能够带动夹套上下运动，当夹套向下运动时，会被内锥套挤压变形，从而夹紧夹套内的轴类零件。
进一步的，壳体上还设有保护盖
进一步的，变形缝的端部开有应力分散孔。
进一步的，杠杆一端与卡板通过万向接头或球头节联接。
