Description

一种双刀库双主轴动柱式型材加工中心 技术领域
本发明涉及机械加工技术领域，更具体地说，涉及一种双刀库双主轴动柱式型材加工中心。
背景技术
用于加工铜铝等有色金属或塑料等等长条型的型材的动柱式型材加工中心，大多采用一个主轴一台标准刀库，只能同时用一个主轴加工工件，效率较低，其X轴行程超过1500mm，Y轴行程在300-450mm范围的居多；也有个别专用双主轴动柱式型材加工中心，采用一个非标刀库，安装8组刀柄，在主轴中心距离150mm或以下时实现自动换刀，加工产品的范围非常有限，可自动换刀的数量也较少，而且由于采用非标刀库，刀库生产数量较少、专业刀库厂家不生产，需要机床生产厂家在标准刀库上改造，刀库故障率比标准刀库高。
发明内容
本发明所要解决的问题在于，提供一种双刀库双主轴动柱式型材加工中心，能够同时加工两件宽度大于300mm的长条型工件，提高工作效率和加工范围，并降低加工成本。
为了解决上述技术问题，本发明提供了一种双刀库双主轴动柱式型材加工中心，其包括机床底座、鞍座、立柱、主轴座、刀库支架、第一主轴、第二主轴、第一刀库和第二刀库，所述机床底座为长条型结构，所述机床底座上沿其长度方向上设有X轴导轨，所述机床底座上设有工作台且所述工作台与所述X轴导轨平行设置，所述鞍座设置在所述X轴导轨上，所述鞍座上沿所述机床底座的宽度方向上设有Y轴导轨，所述立柱设置在所述Y轴导轨上，所述立柱上沿其高度方向设有Z轴导轨，所述主轴座为L型结构或U型结构，所述 主轴座的一端设置在所述Z轴导轨上，所述第一主轴和第二主轴分别设置在所述主轴座的末端的两侧，所述第一主轴的轴心线与所述第二主轴的轴心线平行且所述第一主轴的轴心线和所述第二主轴的轴心线所在的平面与所述工作台相垂直，所述第一主轴的轴心线与所述第二主轴的轴心线之间的距离为300mm-450mm，所述刀库支架设置在所述立柱的顶面，所述第一刀库通过第一安装轴可转动地安装在所述刀库支架上，所述第二刀库通过第二安装轴可转动地安装在所述刀库支架上，所述第一安装轴在所述工作台上的投影与所述Y轴导轨平行，所述第二安装轴在所述工作台上的投影与所述第一安装轴在所述工作台上的投影之间的夹角为30°-90°，所述第一刀库和所述第二刀库均为夹臂式刀库。
作为本发明优选的方案，所述第一主轴的轴心线与所述第二主轴的轴心线之间的距离为350mm-450mm。
作为本发明优选的方案，所述刀库支架为L型结构或U型结构。

作为本发明优选的方案，所述升降门包括升降气缸，所述升降气缸的缸体固定在所述机床底座上，所述升降气缸的活塞杆与所述倒U型外罩连接。
实施本发明的一种双刀库双主轴动柱式型材加工中心，与现有技术相比较，具有如下有益效果：
本发明中的立柱通过鞍座在机床底座左右移动，立柱通过Y轴导轨在鞍座上前后移动，主轴座通过Z轴导轨在立柱上上下移动，使主轴座上的第一主轴和第二主轴任意移动，第一主轴在第一刀库选择对应的刀具，第二主轴在第二刀库选择对应的刀具，第一主轴与第二主轴之间的距离300mm-450mm之间，能够同时加工工作台上两件宽度大于300mm的长条型工件，且无需移动工件，提高工作效率，而且第一主轴的轴心线和第二主轴的轴心线所在的平面与工作台相垂直，能够有利于加工装夹和对型材加工中心进行编程；而且由于夹臂式刀库的重量较轻，保证立柱移动性能好，夹臂式刀库的容量较大，满足不同的加工需求，大幅缩短加工时程，降低生产成本，通过将设置第一安装轴在工作台上的投影与Y轴导轨平行，以及第二安装轴在工作台上的投影与第一安装轴在所述工作台上的投影之间的夹角设置为30°-90°，避免第一刀库与第二刀库在旋转过程中出现干涉现象，保证运行正常。
