Description

一种双头钻攻机床 技术领域
本实用新型涉及一种加工中心工作台，尤其涉及一种立式加工中心的双头钻攻机床。
背景技术
目前许多的连接轴、阀门等机械零件都需要进行孔类加工，加工机床一般采用单个钻头，加工时零件需要进行旋转，对另一面进行钻孔，操作繁琐，浪费时间，旋转后精度无法保证，因此后来研发出了双头钻孔机床。
现有的双头钻孔机床普遍采用工作台固定，钻孔头实现横向和纵向的移动，由于两侧对称设置，故而这就使得机床的占地面积比较大，而且由于两侧都要移动，钻孔的同心度难以把控，两侧的移动速度也难以同步控制。
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，提供一种双头钻攻机床，将工作台设置成纵向移动，而钻孔机构只需要横向移动即可，可以确保两侧同步加工时的同步性，而且可以有效减小整个机床的占地面积。
为实现上述目的，本实用新型提出如下技术方案：一种双头钻攻机床，包括床身，安装在床身中间的工作台机构以及对称安装在工作台机构两侧的钻攻机构，其中：
工作台机构包括基座，滚珠丝杆，第一驱动电机及工作台，基座安装在床身表面，其中间有个内凹槽，滚珠丝杆通过轴承座安装在内凹槽内，且一端与第一驱动电机连接，所述内凹槽两侧边表面安装有线轨，工作台背面安装在滚珠丝杆的丝杆螺母上，且两侧与线轨固定实现滑动；
所述钻攻机构包括第二滚珠丝杆，第二驱动电机，主轴箱以及加工刀头，第二滚珠丝杆通过轴承座安装在床身表面，其一端连接有第二驱动电机，主轴箱底面与第二滚珠丝杆的丝杆螺母固定，两侧安装有滑板，且滑板对应的床身表面安装有配合的滑槽，加工刀头安装在主轴箱上正对工作台。
作为优选，所述第二驱动电机通过电机支架安装在床身表面。
作为优选，所述内凹槽一侧成型有电机安装座，第一驱动电机固定在电机安装座上。
作为优选，两侧的钻攻机构位于同一直线。
有益效果：本实用新型所揭示的一种双头钻攻机床，其具有如下有益效果：采用工作台纵向移动，钻攻机构横向移动的形式，可以极大的缩小整个机床的占地面积，采用工作台纵向移动的形式配合同一直线的两侧钻攻机构，可以确保钻孔的同心度，且加工时只需工作台移动，提升了移动速度，以及定位精确度。
附图说明
图1是本实用新型的主视图；
图2是本实用新型的俯视图。
具体实施方式
下面将结合本实用新型的附图，对本实用新型实施例的技术方案进行清楚、完整的描述。
如图1～2所示，本实用新型所揭示的双头钻攻机床，包括床身1，安装在床身中间的工作台机构以及对称安装在工作台机构两侧的钻攻机构，且两侧的钻攻机构位于同一直线，工件固定在工作台机构上，通过两侧的钻攻机构进行钻孔加工。
具体说来，所述工作台机构包括基座2，滚珠丝杆3，第一驱动电机4及工作台5，其中基座2安装在床身1表面，其中间有个内凹槽6，内凹槽一侧成型有电机安装座7，第一驱动电机固定在电机安装座上，滚珠丝杆通过轴承座安装在内凹槽里，且一端部与第一驱动电机连接，内凹槽两侧边的表面安装有线轨8，工作台安装在滚珠丝杆的滚丝杆螺母上，其背面两侧与线轨固定实现滑动。
