具体实施方式
下面结合附图对本申请的具体实施方式做说明。
为了说明本申请的技术方案，还定义了如图1中箭头所示的上、下、前、后、左以及右。本实施中所说的上下左右均以图1中的切割装置所在的状态为例。
切割装置1000包括切割系统1，切割系统1指的是完成切割作业的一系列组件，切割系统1主要包括切割组件10以及驱动组件20等。根据切割装置1000的功能不同，切割系统1也有所区别，本申请的切割装置1000以台型切割装置为例，例如以斜锯为例，如图1所示的切割系统1还包括工作台以及支撑切割系统的机架等。
如图1所示，切割装置1000包括一种切割系统1，切割系统1包括切割组件10’和驱动组件20’，切割组件10’包括切割件(图1未示出)和至少部分围绕所述切割件设置的护罩110’。驱动组件20’为切割系统提供动力。为了实现护罩110’的锁定，通常设有连接护罩110’和机架的连动杆3。连动杆3靠近护罩110’的一端设有滑动孔，护罩110’通过滑动柱与滑动孔连接，当护罩110’转动时，滑动柱在滑动孔中运动。护罩110’可以在第一位置和第二位置之间转动。示例性的，第一位置可以参考图1，第二位置可以参考图2，护罩110’在第二位置时对于切割件的覆盖面积大于护罩110’在第一位置时对于切割件的覆盖面积。
当护罩110’在外力作用下由如图1所示的第二位置运动到第一位置时，滑动柱从滑动孔的一端运动到另一端，在这种情况下依靠摩擦力、重力以及连动杆3对滑动柱的作用力等力的综合作用，护罩110’维持在第一位置静止。在该种结构中，若护罩110’在第一位置时被施加了外力，如操作人员的误操作等， 会打破护罩110’平衡并使护罩110’下落，影响正常操作。在该种结构中，还有一种情况是当连动杆3和滑动柱的连接过于紧密时，护罩110’往往不能轻易落到第二位置，若在这种情况下误触开关导致切割装置1000启动，切割件高速旋转会对操作者造成危险。
如图2所示，本申请提供另一种适配图1中切割装置1000的切割系统1，包括切割组件10和驱动组件20，切割组件10包括切割件120和至少部分围绕所述切割件120设置的护罩110，驱动组件20包括为所述切割系统1提供动力的马达211(见图4)，切割件120在马达211驱动下转动。护罩110在第一位置和第二位置之间运动，例如可以绕第一轴线101在第一位置和第二位置之间转动。在一定情况下，护罩110可以在第一位置下保持静止，当有其他部件作用时，护罩110被释放并自由下落，转动到第二位置。该第二位置是指不同于第一位置的多个护罩110可能停留位置的集合，若护罩110与切割装置的其他部件发生干涉，则护罩110会停留在第二位置，其他部件如工作台等，或者护罩110在重力等作用下停留在第二位置。护罩110在第二位置时对于切割件120的覆盖面积大于护罩110在第一位置时对于切割件120的覆盖面积。
如图3所示，驱动组件20包括机壳210，机壳210内设有马达211和传动装置，马达211通过传动装置连接切割件120。马达211为切割件120提供旋转的动力。机壳210设置在护罩110左右方向上的一侧。
切割系统1还包括第一把手30，第一把手30设置为供使用者握持并操作切割装置。在本实施例的斜锯中，切割系统1可以相对于工作台运动，通过操作第一把手30移动切割系统1的相对位置。为了便于操作，第一把手30一般设于靠近切割组件10的地方。在本实施例中，第一把手30连接于机壳210，并向切割系统1的前侧延伸。
第一把手30上设有设置为控制马达211切换状态的开关组件310，开关组件310包括第一状态和第二状态。在一些具体地实施例中，第一状态指开关组件310处于关闭状态，第二状态指开关组件310处于开启状态。如图4所示，当开关组件310位于第一状态时，所述切割系统1断电且所述护罩110位于第一位置。如图6所示，开关组件310位于第二状态时，切割系统1启动且所述护罩110位于第二位置。开关组件310包括能够导通的电子元件，上述的第二状态是指开关组件310内的电子元件导通的状态，第一状态指的是开关组件310内电子元件不导通的状态。
如图3所示，第一把手30形成握持部320，握持部320设置为供使用者握持，开关组件310设于握持部320。第一把手30包括壳体300，握持部320形成于壳体300上并具有开口321。开关组件310设于开口321内，并设于开口 321的一侧。
如图5所示，开关组件310包括第一按压部311和第二按压部312，第一按压部311和第二按压部312之间通过连接部313连接，第一按压部311和第二按压部312之间具有间隙，以供使用者手部进行操作。第一按压部311和第二按压部312分别位于开口321内的两侧。开关组件310沿第一方向X(见图4)运动时，开关组件310由第一状态切换至第二状态。开关组件310沿相反于第一方向X的第二方向运动时，开关组件310由第二状态切换至第一状态。开关组件310通过第二转轴315(见图4)连接第一把手的壳体300，开关组件310绕所述第二转轴315转动。
第一把手30包括锁定件330(见图5)，锁定件330设于开关组件310和护罩110之间，并与开关组件310联动。当开关组件310位于第一状态时，锁定件330将所述护罩110定位于第一位置。当开关组件310位于第二状态时，锁定件330释放护罩110，护罩110随即到达第二位置。锁定件330形成有锁定部331，护罩110形成有与锁定部331结合的定位槽111，当锁定部330与定位槽111结合时，护罩110位于第一位置。当护罩110位于第一位置时，第一把手30位于护罩110的一侧。锁定件330通过第一转轴332与第一把手30的壳体300转动连接，锁定部330绕第一转轴332转动。
锁定件330与开关组件310联动，并随着开关组件310的转动而转动。开关组件310朝向护罩110的一端形成有突出的限位部314，当开关组件310位于第一状态时，限位部314抵靠锁定件330，如图5所示，在这种情况下锁定件330位于锁定位置。当开关组件310位于第二状态时，限位部314释放锁定件330，如图6所示，在这种情况下锁定件330位于释放位置。第一把手30包括偏压件316，偏压件316连接锁定件330并为锁定件330提供作用力。当开关组件310位于第一状态时，限位部314抵靠锁定件330使锁定件330与定位槽111配合以锁定护罩110，并且锁定件330压缩偏压件316。当开关组件310位于第二状态时，即开关组件310离开锁定件220时，偏压件316由压缩状态复原，并提供锁定件330释放的作用力。锁定件330还可以设有设置为与偏压件316连接的偏压部。
锁定件330与限位部314的抵靠处设有限位槽333，限位槽333与限位部314形状相配合。如图5所示，当开关组件310位于第一状态时，限位部314抵靠限位槽333。如图6所示，当开关组件310位于第二状态时，限位部314脱离限位槽333，释放锁定件330，如图6所示，在这种情况下锁定件330位于释放位置。释放位置的锁定件330收回至壳体300的容纳空间内。
在其他实施例中，开关组件310可以不设置在第一把手30上，或者在其他 类型的切割装置中不设置把手，则开关组件310至少设置在临近护罩110的位置。
第一把手30还设有限位件340(见图6)，当开关组件310位于第一状态时，限位件340对开关组件310具有作用力以使开关组件310与护罩110相对静止。限位件340能够在外力作用下发生形变，开关组件310从第一状态切换至第二状态时，开关组件310使限位件340形变，以使限位件340对于开关组件310的作用力减弱直至小于开关组件310作用在限位件340上的外力。限位件340包括弹性件341，弹性件341向外伸出并在开关组件310处于第一状态时抵靠开关组件310的一端，例如抵靠第一按压部311朝向护罩110的一端。当开关组件310位于第一状态时，弹性件341被挤压产生对于开关组件310的作用力，使得开关组件310更稳定地维持在第一状态。当开关组件310在外力作用下运动到第二状态时，弹性件341复位，作用力减小或消失。
切割组件10还包括固定罩130(见图4)，固定罩130设于切割件120上方，并至少部分包围切割件120设置。固定罩130设于护罩110和切割件120之间，固定罩130相对保持静止。即，护罩110与固定罩130重叠设置，护罩110在第一位置与固定罩130的重叠面积大于护罩110在第二位置与固定罩130的重叠面积。固定罩130使得切割件120一部分露出，一部分设于固定罩130内。对于切割件120在固定罩130中露出的部分，护罩110在第一位置时不覆盖或者少覆盖该露出部分，护罩110在第二位置时覆盖切割件120露出部分，以保证切割系统1使用安全性。固定罩130连接机壳210，机壳210连接壳体300。
切割系统1还包括第二把手40(见图4)，第二把手40设于护罩110的后方，可以设于固定罩130和机架的连接处，第二把手40设置为辅助调整切割系统1的位置。当切割装置1000为非台型切割装置时，第二把手40可作为主把手。
在本申请的另一实施例中，可以通过对于切割系统1的控制实现护罩110和开关组件310的联动。切割系统1还包括传感元件和控制器(图中未示出)，传感元件一般设于护罩110的边缘处，或者靠近护罩110的位置，控制器一般被集成于切割装置1000的主电路板上。传感元件检测护罩110的位置并将信息传输给控制器。当开关组件310切换至第二状态时，控制器首先判断护罩110的位置，当护罩110位于第二位置时，控制器使切割系统1启动。切割系统1还包括指示元件，当控制器还接收到开关组件310达到第二状态和护罩110位于第一位置的信号时，控制器使指示元件发出指示信号，该指示信号包括声音、灯光等，提示使用者此时护罩110的状态不满足切割系统1的启动要求。
本申请的有益之处在于：本申请通过将护罩与开关联动，提高了切割系统启动的安全性，能够有效地防止误伤操作者。
控制器对于切割系统1的控制逻辑如图7所示，控制过程为：控制器检测开关组件310的状态，当开关组件310为第一状态时，不进行操作，直到开关组件310被切换至第二状态；当开关组件310切换至第二状态时，控制器查询传感元件传输的信号，传感元件设置为判断护罩110的位置；当传感元件反馈的信号显示护罩110位于第一位置时，控制器控制指示元件发出提醒，提醒的形式包括声音报警、指示灯闪烁等；当传感元件反馈的信号显示护罩110位于第二位置时，控制器控制切割系统1执行主循环，即，启动马达211进行切割等。
传感元件包括但不限于光电开关、微动开关、磁吸式开关以及编码器等。当传感元件为光电开关、微动开关、磁吸式开关以及类似元件的一种时，则将传感元件设于护罩110的边缘处。当传感元件为编码器时，传感元件设于护罩110的转动轴处，通过检测转动轴转动的角度输出位置信号。
