一种磨刀口可移动的磨刀器
技术领域
本发明涉及磨刀器领域，尤其是一种磨刀口位置可移动的磨刀器。
背景技术
目前市场上，磨刀器的磨刀部件主要有两种：一种是用硬质合金做成的磨刀片，利用其坚硬的棱边切削刀刃。另一种是用合成材料做成的磨刀棒，利用其具有研磨作用的外表面对刀刃摩擦，使刀具更加锋利。立式磨刀器的结构大致为：两个相同的磨刀部件一前一后交叉放置，在两个磨刀部件之间组成“V”形磨刀口。使用时，将刀刃按在“V”形磨刀口底部抽拉，让刀刃从两个相互交错的磨刀部件之间经过。这种结构的磨刀器，无论磨哪一侧，另一侧都要与对面的磨刀部件接触摩擦，力度控制不当，很容易造成卷边，影响磨刀效果。并且此类磨刀器的磨刀口都是固定的，磨刀部件上起到磨刀作用的只是磨刀口底部的一小段区域，其它大部分区域很少甚至根本用不到，比较浪费磨刀部件。

磨刀架1上设置有左右对称、开口朝上，呈V形排列的固定槽，用于放置磨刀片21；后面设置有横向的导槽102和固定转动轴4的定位骨101；
转动轴4上设计有两段螺旋方向相反的螺纹402（也可以是相互对称的两段螺纹）；转动轴4的一端设计有转动轮401；靠近转动轮401的一侧设计有限位骨403；转动轮401的外周设计有防滑纹。
左右立杆组件3的两个滑块32上都设计有凸起的导块3201和螺纹；两个滑块32上的螺纹螺旋方向相反，分别与转动轴4上的两段螺纹相匹配。
如图2、图3和图4所示，磨刀片21设置在磨刀架1的固定槽中，顶部用固定螺丝51和压紧扣52固定。磨刀片21的两端设置有对称的凹陷，用于固定槽和压紧扣52嵌入固定，以防止磨刀片21脱落。转动轴4通过固定螺丝61和固定片62横向安装在支架1的定位骨101上。组装后，固定片62夹在两个限位骨403之间，与转动轴4形成相互嵌合的限位结构，可以防止转动轴4左右移动。立杆组件3夹在磨刀架1和转动轴4之间，两个立杆31以左右磨刀片21的对称平面A为对称平面，左右对称。两个滑块32朝向磨刀架1一侧的导块3201，伸入到导槽102中。两个滑块32朝向转动轴4一侧的螺纹分别与转动轴4上的两段螺纹402相匹配嵌合。转动转动轮401时，转动轴4上的两段螺纹402的螺旋曲面会分别推动两个滑块组件3同时同步向相反的方向移动。左右立杆31与同侧的磨刀片21形成的V形磨刀口的底部就会沿磨刀片21的边缘同时上升或下降。
本实施例中，滑块32紧贴磨刀架1背面，两者之间形成平面配合，距离固定，因此滑块32无法旋转。滑块32上的导块3201伸入到磨刀架1的导槽102中，形成能左右滑动的嵌合结构，导块3201既可以在上下方向上起到定位作用，又能承受来自立杆31扭力，避免滑块32倾斜。同样的，此嵌合结构也可以设计为：磨刀架上设置凸出的导条，滑块上设置对应的导槽，使凸出条伸入到导槽中。滑块32与磨刀架1之间的这种嵌合结构也可以起到限制滑块旋转的作用。
进一步的，如图6所示，滑块32上的螺纹也可以设计为凸块3202，同时转动轴4上的螺纹设计成与凸块3202相匹配的螺纹槽。转动轴4旋转时，螺纹槽的螺旋曲面会推动凸块3202移动，从而带动滑块组件3横向移动。
更进一步的，只要滑块（32）和转动轴（4）上设置有相互匹配的凹槽或凸起，且凸起或凹槽的其中之一呈螺旋形；滑块（32）被限制旋转，转动轴（4）原地转动时，螺旋形凸起或凹槽的螺旋曲面会推动滑块（32）沿着转动轴（4）的轴心方向移动。
以上实施例中，磨刀器上的磨刀片21共有4片：两片安装在磨刀架1的固定槽中，另两片备用的磨刀片21放置在磨刀架1底部，由设置在底部的防滑垫7承托固定。进一步的，备用的磨刀部件也可以设置在磨刀器的其它位置，方便使用者替换使用。
如图5所示，本实施例在使用时，如果刀具8只从其中一个磨刀口经过，刀刃的一侧就会被磨削，可以磨单侧刀刃的刀具；如果刀具8分别从两边的磨刀口经过，刀刃的两侧就都会被磨削。磨刀过程中，两侧磨刀部件互不影响，容易操作。
图7是本发明实施例2的分解示意图，本实施例包括的主要部件有：磨刀架1、磨刀部件2、立杆组件3、转动轴4、磨刀部件固定组件5和转动轴固定组件6。其中磨刀部件2有两组，每一组都是由一个磨刀片21和一个磨刀棒22搭配构成；两组磨刀部件2左右对称，前后方向上并列放置；每组中的磨刀片21与磨刀棒22底部相近，顶部相远，在竖直方向上的倾斜角度相同，呈V形排列。两组磨刀部件中相互对称的两个磨刀部件长度方向的中心线处在同一平面上。固定磨刀部件2的磨刀部件固定组件5有三组，每组都是由一个固定螺丝51和一个压紧扣52构成。两组磨刀部件2中靠近对称中心的两个磨刀片21由同一个磨刀部件固定组件5固定。立杆组件3是由滑块32和固定其上的立杆31组成，立杆组件3设置有两个，左右对称的放置在磨刀部件2后面，其对称平面A与两组磨刀部件2的对称平面相同。
如图7、图8、图9和图10所示：磨刀架1上设置有放置磨刀部件2的固定槽，固定槽开口向上。磨刀架1的后面设置有U形支撑骨103。磨刀片21和磨刀棒22的两端的中心位置设计有突起部。磨刀片21的突起部上下相同，左右对称。组装后，突起部分别嵌入到压紧扣和磨刀架1的固定槽中，可以避免磨刀部件活动或脱落。
转动轴4上有两段螺旋方向相反（也可以是左右对称）的螺纹402，两段螺纹之间有两圈凸起的限位骨403，转动轴的一端设计有转动轮401，转动轮401外周设计有防滑条纹。
滑块32上设计有螺纹和可以让导柱64穿过的导孔；左右两侧滑块上的螺纹螺旋方向相反，分别与转动轴4上的两段螺纹402匹配。
转动轴固定组件6由螺丝61、固定架63和导柱64构成，固定架63上设置有用来轴接转动轴4的孔。
转动轴4穿过固定架63上的导孔，与两个立杆组件3通过螺纹活动连接。
两根导柱64从左右滑块32的导孔中穿过，两端分别固定在固定架63上。对滑块32起到定向作用，又可以承受来自立杆31扭力，避免滑块32倾斜、旋转。
转动轴固定组件6通过螺丝61将转动轴4和滑块组件3一起固定在磨刀架1的后面，转动轴4呈左右横向状态，立杆31呈竖立状态。
组装后，如图10所示：磨刀架1上的U形支撑骨103夹在转动轴4上的两个限位骨403之间，形成相互嵌合的限位结构，可以防止转动轴4左右移动。同时又能承托来自立杆31的扭力。左右两组磨刀部件2的对称平面A，也是左右两个立杆31的对称平面。转动轴4上的两段螺纹402也以平面A为对称平面左右对称。当转动转动轴4时，两侧的立杆31就会同时同步向相反的方向移动。立杆31与同侧的磨刀片21或磨刀棒22所形成的V形磨刀口的底部就会同时同步上升或下降。
相似的，转动轴4上的两个限位骨403组成的限位结构，也可以看作是一个限位槽，U形支撑骨103伸入其中，形成限位机制。
进一步的，转动轴4上也可以设置一个限位骨，同时U形支撑骨103的U形面上设置有限位凹槽，让限位骨伸入到限位凹槽中，形成限位机制。
如图10和图11所示，对刀具8进行打磨时，转动转动轴4，将立杆31移到磨刀片21的后面，用两个磨刀片21进行快磨，也可以转动转动轴4将立杆31向外移到磨刀棒22的后面，用两个磨刀棒22进行细磨。两种磨刀方式，方便使用者选择。同时两侧的磨刀部件2并排放置，避免相互干扰，磨刀更方便。
在以上两个实施例中，立杆既可以垂直竖立在磨刀部件后面，也可以小角度倾斜竖立在磨刀部件后面，以方便刀具放置。固定磨刀部件的螺丝都可拆装。磨刀部件可更换使用，不会浪费磨刀架和其它部件。同时，磨刀片在长度方向上的横截面是长方形，两端设计有相同的凹陷或突起，磨刀片整体在长度和宽度两个方向上平面对称；上下或左右交换位置后磨刀片的两端仍然可以分别与压紧扣和磨刀架的固定槽底部嵌合固定。这样磨刀片就可以上下颠倒或/和左右旋转后重复使用。同样的，磨刀棒两端的突起部在垂直于长度方向的横截面可以设计为正多边形，例如：三角形、四边形、五边形、六边形等均可。见图9，本实施例中，在磨刀棒的两端突起横截面为正六边形；磨刀棒的磨刀面被磨损后，就可以旋转一个角度重新使用；延长了磨刀棒的使用寿命。
特别说明：为了对本发明的描述更加清晰和便于理解，在对以上两个实施例的描述的中，对具有相同功能的部件或结构进行了统一命名；如左右两侧的滑块，虽然结构不同，但功能相同，所以统一称为滑块；固定磨刀部件的压紧扣，虽然结构上需要分别匹配磨刀片和磨刀棒，但功能相同，都是用来压紧固定磨刀部件，所以统一称为压紧扣；相应的，磨刀部件固定组件、定位骨、固定架也是按照这种规则命名的。
以上实施例中的采用的对称结构，也可以变更为非对称结构也是可以成立的。例如转动轴上的两段螺纹，只要旋转方向相反，不对称也是成立的。立杆既可以竖直方向设置，也可以采用非竖直方向的设计方案：与竖直方向倾斜一定角度；只要立杆与磨刀部件之间的形成V形磨刀口，即可实现充分利用磨刀部件的目的。同时，相临的两个磨刀部件之间，也可以是顶部上近，底部相远，组合成倒V形。立杆与磨刀部件之间一样能形成可移动的V形磨刀口。
以上参照附图对本发明的实施例进行了说明。需要特别指出的是以上仅为发明的优选实施例而已，并不用于限制本发明。尽管参照前述实施例对本发明进行了详细说明，对于本领域的从业人员来说，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换。凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均包含在本发明的保护范围之内。
