Abstract

一种滑动式切断锯，包括底座装置、马达、锯片[8]、机头架[6]，它还包括滑枕[4]，在转盘[2]的直径方向上开有滑枕导槽，所述的滑枕[4]可滑动地插在滑枕导槽内，所述的滑枕[4]的后端部与支持件[5]的下部相连接，所述的机头架[6]的后端部与支持件[5]的上部相连接。通过滑枕在转盘上滑动，因此支撑机头架的支持件可以作得粗大且刚性较好，滑枕的前部始终在锯片的下方，在锯片向后滑动后，滑枕也跟着向后滑动，工作时可以节省转盘的占用空间。

Description

滑动式切断锯
技术领域
本发明涉及一种切断锯。
背景技术
美国专利US5239906公开了一种切断电圆锯专利，它包括底座、滑动件、导向装置、滑动装置等，该导向装置为一个悬臂，滑动装置可在该导向装置上前后方向滑动，但是，这种悬臂由于需要机头部分在上面滑动，因此其刚性较差，直接影响了锯片对工件的加工精度。
发明内容
本发明的目的在于提供一种机头架的支撑装置具有较高刚性的滑动式切断锯。
本发明的技术方案是：一种滑动式切断锯，包括
底座装置，该底座装置包括底座、与底座枢轴连接的转盘；
马达，该马达包含一个有旋转轴线的电枢；
锯片，该锯片有一个旋转轴线；
机头架，所述的锯片及所述的马达都设置在该机头架上，所述的马达的电枢旋转轴线与锯片的旋转轴线之间有一段距离并且相互平行，所述的马达与锯片之间通过传动装置相连接；
支持件，支持件上部设有铰接枢轴，机头架通过枢轴与支持件相连接；
它还包括滑枕，在转盘的直径方向上开有滑枕导槽，所述的滑枕可滑动地插在滑枕导槽内，所述的滑枕的后端部与支持件的下部相连接，所述的机头架的后端部与支持件的上部相连接。
本发明与现有技术相比具有下列优点：
通过滑枕在转盘上滑动，因此支撑机头架的支持件可以作得粗大且刚性较好，滑枕的前部始终在锯片的下方，在锯片向后滑动后，滑枕也跟着向后滑动，工作时可以节省转盘的占用空间。
附图说明
附图1为本发明的一种使用位置时的左视图；
附图2为本发明的另一种使用位置时的左视图；
附图3为本发明的一种使用位置时的俯视图(去掉机头架及支持件时)；
附图4为本发明的另一种使用位置时的俯视图(去掉机头架及支持件时)；
附图5为本发明的锯片斜切时的俯视图(去掉机头架及支持件时)；
附图6为附图4的A-A方向剖视图；
附图7为附图4的B-B方向剖视图；其中：
1、底座；2、转盘；3、工件护栏；4、滑枕；5、支持件；6、机头架；7、锯片护罩；8、锯片；9、附加支撑件；10、扭簧；11、转盘轴；12、支持件转轴；13、锁定件；14、机头架转轴；15、锯片长槽；16、附加支撑件导槽；17、压板；18、压板；19、支撑脚；
具体实施方式
参见附图，一种滑动式切断锯，包括
底座装置，该底座装置包括底座1、与底座1枢轴连接的转盘2；
马达(图中没有画出)，该马达包含一个有旋转轴线的电枢；
锯片8，该锯片8有一个旋转轴线；
机头架6，所述的锯片8及所述的马达都设置在该机头架上，所述的马达的电枢旋转轴线与锯片的旋转轴线之间有一段距离并且相互平行，所述的马达与锯片8之间通过传动装置相连接，使得马达的动力能传递到锯片8上；它还包括滑枕4，在转盘2的直径方向上开有滑枕导槽，所述的滑枕4可滑动地插在滑枕导槽内，所述的滑枕导槽上设有直线轴承，使得滑枕与滑枕导槽能够更好地滑动连接，所述的滑枕4的后端部与支持件5的下部相连接，所述的机头架6的后端部与支持件5的上部相通过机头架转轴14相枢轴连接。
所述的滑枕导槽沿着转盘2的直径方向贯穿整个转盘2，在滑枕4向前滑动到极限位置时(如附图2所示)，所述的滑枕4的前端部伸出转盘2之外。所述的滑枕4的前部开有锯片长槽15，该锯片长槽15始终位于所述的锯片8的下方，并在锯片8下压时，锯片8插入所述的锯片长槽15内。所述的底座1的上表面两侧分别枢轴连接有附加支撑件9的一端部，所述的附加支撑件9水平设置，其另一端部向前伸出转盘2之外，所述的附架支撑件9一般在附图4及附图2所示的状态下使用，可与滑枕4共同用于支撑被加工的工件。所述的附加支撑件9的转动轴上套有扭簧10，该扭簧10的一端与附加支撑件9相连接，扭簧10的另一端与转盘2相连接。在附图5所示的状态下，由于锯片转动，因此转盘2及滑枕4也跟着转动，则滑枕4可把附加支撑件9的前端部推向左侧。所述的转盘2的上表面设有沿圆周方向延伸的附加支撑件导槽16，所述的附加支撑件9上的支撑脚19位于该附加支撑件导槽16内。
