Description

一种钻头锁紧设备及钻头
技术领域
本发明涉及一种外科使用的骨钻电机，尤其涉及其中钻头锁紧设备及钻头。
背景技术
   在外科手术中，开颅钻、铣刀和磨钻是较为常用的开颅工具。开颅钻包括主机、减速器、锁紧座和钻头，钻头包括前部的刀刃部和后部的传输杆。钻带有传输杆钻头，锁紧座通过螺纹连接于减速器的前部，钻头穿过锁紧座与减速器的动力输出相接。锁紧座的作用是卡紧传输杆，防止在工作时，钻头脱落。现有的锁紧设备是通过卡勾进行锁紧，存在安装不方便，不易使用的缺点。
发明内容
本发明的目的是提供一种使用方便的钻头传输杆锁紧设备及钻头。
为了实现上述目的，采用以下技术方案：
一种钻头锁紧设备，其特征在于：所述设备包括：具有通孔的凸台，所述凸台上方小圆柱体的内壁上设置有轴承，所述凸台还套有锁紧套，锁紧套的上部内壁上设置有凸起，锁紧套下部内壁呈锥形面；锥形面的底面与凸台的上底面之间设置有弹簧，压片与凸台的上方小圆柱体的顶部的外壁螺纹连接并压住凸起；凸台上方小圆柱体的壁上与锥形面对应的位置设置有锥形孔，所述锥形孔内设置有钢珠。
为了使得传输杆可以受力均匀，所述轴承为两个，分别位于外壁下方和上底面的上方。
为了保证两个轴承的牢固，所述两个轴承之间设置有支撑体。
为了方便连接减速器，所述凸台下方大圆柱体的内壁上设置有内螺纹。
一种与上述钻头锁紧装置配合的钻头，包括前部的刀刃和后部的传输杆，其特征在于：所述传输杆上设置有凹槽。
采用本结构，当需要插入传输杆时，只需将锁紧套下压，此时，锥形面下移，钢珠向外滚出。传输杆到达指定位置后，松开锁紧套，由于弹簧的作用，锁紧套上升，锥形面抵住钢珠向内运动，卡住传输杆上的卡槽，将传输杆固定。这种锁紧方式，锁紧与松开的操作简单、方便，且锁紧时比较牢固，安全性能较好。
附图说明
图1为本发明实施例中钻头锁紧设备的结构示意图；
图2为本发明实施例中钻头的结构示意图。
具体实施方式
    下面结合附图及具体实施例对本发明做进一步的描述：
     如图1及图2所示：
一种钻头，包括前部的刀刃部和后部的传输杆，传输杆13上设置有凹槽14。
一种钻头锁紧设备，包括：具有通孔的凸台1，凸台上方小圆柱体的内壁上设置有轴承8，轴承8为两个，分别位于外壁7下方和上底面10的上方。两个轴承8之间设置有支撑体12。两个轴承可以有效的保证传输杆转动时的平稳，减少发热，上底面10上还螺纹连接有压紧件15，用以顶紧轴承8和支撑体12，增加了轴承8的牢固度，不易脱落。凸台还套有锁紧套2，锁紧套2的上部内壁上设置有凸起5，下部内壁呈锥形面3；锥形面3的底面与凸台的上底面10之间设置有弹簧9；压片6与凸台的上方小圆柱体的顶部的外壁7螺纹连接并压住凸起5；凸台上方小圆柱体的壁上设置有通向凸台通孔的锥形孔11，锥形孔11内设置有钢珠4。锥形孔11对应在钻头的传输杆13的位置上设置有凹槽14。凸台1下方大圆柱体的内壁上设置有内螺纹。在此实施例中，当然锥形孔11和钢珠4的个数分别为两个。作为一种等同的变形，可以分别设为三个，这样的话，锁紧的效果将更好。
以上所述，仅是本发明的实施例，并非对本发明的任何形式上的限制，任何熟悉本专业的技术人员，在不脱离本发明技术方案的范围内，当可利用上述揭示的技术内容做出些许更改或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案内容，依据本发明技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明技术方案保护的范围。
