一种直联机械式加工中心皮带轴
技术领域
本发明涉及一种加工中心皮带轴，特别是涉及一种直联机械式加工中心皮带轴。
背景技术
现有的加工中心皮带轴传动方式多是皮带传动，即采用普通电机驱动，通过皮带带动加工中心主轴转动，松拉刀机构采用气缸推动拉杆的方式。这种皮带轴传动和松拉刀方式存在的缺点是传动不平稳，皮带的振动会影响加工中心皮带轴的正常运转，另外机床结构庞大复杂，占用的空间大，成本高。
发明内容
本发明针对现有技术不足，尤其是小型加工中心，提供一种直联机械式加工中心皮带轴，通过联轴器将加工中心皮带轴的转轴与电机轴连接传动，松拉刀采用加工中心机床打刀臂推动连接体带动拉杆实现松拉刀，传动更加平稳，简化加工中心机床的结构，空间更加紧凑，降低成本。
本发明所采取的技术方案：
一种直联机械式加工中心皮带轴，包括由转轴、前盖、壳体和连接体组成加工中心皮带轴，加工中心主轴的转轴设置为中空匹配安装有拉杆，该拉杆中部设置有轴向气道，该转轴上段设置有U 形限位径向通孔匹配安装有径向连轴销，该连轴销中空设置有气道结构，中部与拉杆匹配安装，两端与连接体匹配安装，该连接体轴向设置台阶结构，内部设置有气道结构；该转轴上端外径设置有轴向台阶结构，匹配安装有联轴器输出端。
所述连接体台阶面与加工中心机床打刀臂接触。
所述连轴销气道的进气道一端与连接体气道对接，中空出气道与拉杆中部轴向气道对接。
所述连接体气道的进气道一端与定位块出气道对接，出气道一端与连轴销进气道对接。
所述联轴器的输入端与电机轴匹配安装连接。
本发明的有益效果是：
本发明直联机械式加工中心皮带轴，用联轴器取代皮带驱动，优化了驱动方式，传动平稳，采用机械式更换刀具，降低机床的复杂难度，使机床的结构更加紧凑，更加具有经济性。
附图说明
图1：本发明直联机械式加工中心皮带轴结构示意图。
其中：图中标号，1为转轴，2为前盖，3为前密封垫，4为壳体，5为拉爪，6为碟簧调整垫，7为碟簧，8为拉杆，9为后密封垫，10为定位块，11为连接体，12为拉杆连轴销，13为联轴器输出端，14为拉杆连接套。
具体实施方式
下面结合附图，并结合实施例，对本发明做进一步的说明。
如图1所示，本发明是一种直联机械式加工中心皮带轴，包括转轴1、前盖2、壳体4和连接体11组成的加工中心皮带轴，转轴1中空匹配安装有拉杆8，在上段U 形限位径向通孔匹配安装有径向拉杆连轴销12，该连轴销两端与拉杆连接体11匹配安装，中段与拉杆8匹配安装；该转轴上端外径设置有轴向台阶结构匹配安装有联轴器输出端13，同时设置有防尘密封的拉杆连接套14，在拉杆8和弹簧调整垫6之间设置有碟簧7，还设有用于密封轴承的前密封垫3、后密封垫9，同时在靠近连接体11的壳体4一端匹配设置安装有进气的定位块10。
本发明的工作原理：加工中心机床启动后，当电机处于工作状态时，电机轴的转动通过联轴器输出端直接驱动加工中心皮带轴转轴1动，需要换刀时，通过加工中心机床打刀臂作用在连接体11台阶面的力，推动连接体11轴线移动，带动转轴1轴线移动，联轴器的输入端和输出端分离，加工中心皮带轴停止转动，同时在拉杆连轴销12的作用下连接体11的移动推动拉杆8移动，拉爪5涨开实现松刀，换刀完成后，加工中心机床打刀臂脱离连接体11的接触，在碟簧7的作用力下，拉杆8推动转轴1轴向复位移动，推动联轴器输入端和输出端13合并，加工中心皮带轴正常转动。高压气体通过定位块10的气孔进入连接体11气道，经拉杆连轴销12气道到达拉杆8内，在换刀时吹净转轴锥孔内侧壁灰尘。
