Description

锯条的快换夹紧机构
技术领域
本发明涉及一种锯条的夹紧机构。
背景技术
现有技术中，US6209208公开了一种夹紧机构，它是利用一个外部凸轮表面和一个内部凸轮表面组成驱动组件，锁紧组件包括一个外部从动轮表面适合于外部凸轮表面，并且一个内部从动轮表面适合于外部凸轮表面，使得驱动组件转动时，锁紧组件可以径向移动而锁定锯片。这种夹紧机构由于是内部凸轮表面直接压动外部凸轮表面径向移动，因此在驱动组件驱动锁紧组件径向移动时费力，该夹紧机构的大部分零部件都为切削件，使得零部件的装配误差大，并且这种凸轮的加工难度相当大。
发明内容
本发明目的是提供一种结构简单的锯条的快换夹紧机构
为达到上述目的，本发明采用的技术方案是：一种锯条的快换夹紧机构，它包括一个支座、一个滑动地设置于所述的支座上的滑动块、一个与所述的支座枢轴连接的夹紧杠杆，所述的夹紧杠杆在转动轴的一侧被称为压板，夹紧杠杆在转动轴的另一侧被称为被压板，所述的支座上有一个支承面，该支承面位于压板的对面。
由于上述技术方案运用，本发明与现有技术相比具有下列优点：
通过滑动块的滑动，使得滑动块压在被压板上，则压板可以翘起，使得压板与支承面之间出现间隙，则锯条可以插入该间隙内或从该间隙内取出。本发明的零部件少，加工容易，可以降低生产成本。
附图说明
附图1为本发明的滑动块被压下后，压板处于解锁状态下的结构剖视图(锯条正在插入)；
附图2为本发明的滑动块被压下后，压板处于解锁状态下的结构剖视图(锯条已插入)；
附图3为松开滑动块后，本发明的压板处于锁定状态下的结构剖视图；
附图4为本发明的各零部件分解示意图；
附图5为本发明的各零部件装配在一起后的立体图；
其中：1、弹簧；2、锁紧斜面；3、被压板；4、支座；5、转动轴；6、滑动块；7、压板；8、锯条定位孔；9、锯条；10、定位凸柱 11、夹紧杠杆；12、支承面；13、解锁压面；14、通孔；
具体实施方式
参见附图1至附图5，一种锯条的快换夹紧机构，它包括一个支座4、一个滑动地设置于所述的支座4上的滑动块6、一个与所述的支座4枢轴连接的夹紧杠杆11，所述的夹紧杠杆11的转动轴的一侧称为压板7，夹紧杠杆11的转动轴的另一侧称为被压板3，所述的支座4上有一个支承面12，该支承面12位于压板7的下方，所述的支承面12上设有一个朝向压板7凸起的定位凸柱10，在锯条9插入支承面12和压板7之间后，该定位凸柱10插入所述的锯条9上的锯条定位孔8内。
所述的滑动块6上设有一个锁紧斜面2和一个解锁压面13，在压板7处于锁定状态下(如附图3所示)，所述的被压板3的端部与所述的锁紧斜面2相接触，该锁紧斜面2在弹簧1的作用下有向上移动的趋势，使得被压板3在锁紧斜面2的作用下具有沿顺时针方向转动的趋势，则压板7进一步压紧锯片9，此时所述的解锁压面13与所述的被压板3相分离；如附图1和附图2所示，在压板7处于解锁状态下，所述的解锁压面13压在所述的被压板3上，使得被压板3逆时针方向转动，则支承面12与压板7之间的间隙张开，便于插入或拔出锯片9。所述的被压板3的端部出有一个斜面，在压板7处于锁定状态下，该斜面与所述的锁紧斜面2相面接触。在下压滑动块6的过程中，锁紧斜面2向下移动，留出空间，在解锁压面13压到被压板3后，被压板3可以逆时针方向转动。所述的滑动块6与支座4之间设有弹簧1，该弹簧1使得滑动块6上的解锁压面13具有趋于脱离被压板3的趋势。
所述的压板7上开有供滑动块6穿过的通孔14，所述的滑动块6穿过所述的通孔14。所述的被压板3相对于压板7呈大致上90度的弯折。
