Description

一种自动调整臂壳体的加工工装 技术领域
本实用新型涉及一种加工工装，尤其涉及一种自动调整臂壳体的加工工装。
背景技术
自动调整臂一般由壳体，传动部分，单向离合器，控制装置和蜗杆压紧部分等组成，其通过壳体实现安装，故而要在壳体上进行各种安装孔的加工，对于这种加工最见的就是采用立式或卧式加工中心进行加工，然而由于自动调整臂壳体的结构特殊性，无法再加工中心的底座上进行有效稳固的安装，通常需要采用各种气缸配合压块实现各个方位的按压，才可确保加工过程中不会出现位移。
实用新型内容
本实用新型的目的在于克服现有技术的缺陷，提供一种自动调整臂壳体的加工工装，可以实现对自动调整臂壳体的快捷稳固的定位。
为实现上述目的，本实用新型提出如下技术方案：一种自动调整臂壳体的加工工装，安装在加工中心内对壳体进行定位安装，包括基板，安装在基板上的多个定位锁紧机构，其中：
基板两端通过多个支架固定在加工中心的底座上，其表面嵌装有多个定位芯轴，壳体套装在定位芯轴上；
所述定位锁紧机构包括薄型液压缸，水平锁紧机构及两个竖直锁紧机构；
所述薄型液压缸固定在定位芯轴对应的基座背面，其伸缩杆上安装有连接板；
两个竖直锁紧机构对称设置在薄型液压缸两侧，包括多根连杆以及压板，连杆底端具有外螺纹，拧固安装在连接板内，上端穿过基板并固定有压板，通过薄型液压缸带动连接板下移，使得连杆带动压板下移从而压住壳体；
所述水平锁紧机构包括锁紧块，锁紧螺栓，定位块以及定位杆，其中锁紧块及定位块固定在基板上位于定位芯轴两侧，锁紧螺栓拧装在锁紧块内抵住壳体侧面，定位杆一端插装在壳体内，另一端卡在定位块表面的定位凹槽内。
作为优选，所述自动调整臂壳体具有与定位芯轴配合的定位孔，其侧面具有与螺杆配合的插孔。
作为优选，所述定位芯轴包括具有多个安装孔的安装盘，其底面一体成型有嵌入部，上表面具有凸起的定位部，嵌入部嵌装在基板内，通过紧固件将安装盘与基板固定，壳体卡装在定位部上。
作为优选，所述竖直锁紧机构与水平锁紧机构相错位。
有益效果：本实用新型所揭示的一种自动调整臂壳体的加工工装，其具有如下有益效果：
通过在基板上嵌装定位芯轴，配合壳体自身结构中的定位孔，可以确保套装在芯轴上的壳体不会前后左右的移动，考虑到其旋转移动，采用定位杆配合定位块对其旋转位置进行限定，通过锁紧螺栓从另一侧抵住，可以实现壳体在水平面上各个方向的定位锁紧；
采用对称设置的压板配合螺杆，连接板以及液压缸，控制两侧压板同步下压，确保两侧上下压力一致，实现对壳体竖直方向的定位，
本工装采用一个液压缸作为动力源，配合其余结构的设计可以实现对壳体的精确定位，降低加工难度，提升加工效率。
