Description

用于刀具同步动作的运动机构以及切刀 技术领域
本发明涉及切刀传动装置，属于切割工具领域，尤其涉及一种用于刀具同步动作的运动机构以及切刀。
背景技术
切刀又被称为切刀机或切边机，包括电动和手动操作两种方式，常见的切刀通常由工作台面、刀具、手柄等部件构成，手柄和刀具为一体结构，刀具与工作台面铰接，通过手柄操作对材料形成切割。
现有用于木板、地板、PVC板等建筑装修材料处理的切刀，虽然结构上比先前的切刀有改进，但体积仍然较大，不方便搬运和携带，成本较高；结构简单，切刀的功能单一。此类切刀中电动方式的，由于刀片速度快、多次摩擦材料，易产生灰尘且较难进行集尘除屑；手动方式的，阻力较大，使用较为费力。尤其是用于塑料地板切割，由于冲击力较大，会损坏塑料地板内部结构，导致切面开裂等问题；切割时也极易发生材料崩飞，存在安全隐患。
如中国专利(授权公告号CN204914008U)公开了“一种塑料地板切割机”，用以切割一塑料地板，包含有，一机架本体，其上具有一工作台面，所述工作台面形成有上下贯通的一贯通槽；以及，一切刀本体，其具有相对的第一端及第二端，其中，所述切刀本体的第一端为切割部，所述切刀本体的第二端为握持部；又，所述切刀本体的第一端处于所述贯通槽内并与所述机身本体转动连接，使得所述切刀本体的转动投影面落在所述贯通槽。本实用新型的优点在于：可方便地剪切各种塑料地板，极大地提高铺设塑料地板的效率。
再中国专利(授权公告号CN 203993987U)公开了“一种塑料地板铡刀切割 机”，包括工作台面、辅助台面、标尺、组合刀片、刀头夹板、手柄、手把、辅助刀座和支撑脚，工作台面一侧设置有辅助台面，辅助台面通过工作台导槽与工作台面滑动配合，辅助台面上设置有标尺座托盘，标尺座托盘通过辅助台导槽与辅助台面滑动配合，标尺座托盘上固定连接有标尺，工作台面的一端通过刀头夹板连接有组合刀片，组合刀片与手柄连接，手柄上固定连接有手把，组合刀片上还通过螺栓连接有辅助刀座，工作台面下方设置有可旋转的支撑脚。
发明内容
本发明提供一种用于刀具同步动作的运动机构以及切刀，用于解决现有的切刀在使用时较为费力、容易损伤板材以及易发生材料崩飞等问题。
为了实现本发明的目的，采用以下技术方案：
用于刀具同步动作的运动机构，包括摇杆机构、传动机构和偏心旋转机构，偏心旋转机构用于带动刀具组件上、下移动；所述摇杆机构、偏心旋转机构至少设置有两套，多套摇杆机构之间通过传动机构实现同步动作；所述偏心旋转机构包括偏心轮和转轴，转轴穿过偏心轮后与摇杆机构连接，所述偏心轮安装在支架上，所述偏心轮与摇杆机构之间固定连接，偏心轮通过摇杆机构的摆动可以在支架上旋转。
为了进一步提高本发明的效果，还可以采用以下技术方案：
如上所述的用于刀具同步动作的运动机构，所述摇杆机构包括在支架两侧对称设置的两套摇杆，所述偏心轮安装在支架上开设的支架孔内，所述摇杆与偏心轮通过连接件固定连接。
如上所述的用于刀具同步动作的运动机构，所述传动机构包括推杆轴、推杆，多套摇杆机构分别配置对应的推杆轴，推杆轴与摇杆机构活动连接，所述 推杆与多套推杆轴固定连接。
如上所述的用于刀具同步动作的运动机构，所述推杆上设有弹簧和弹簧罩，弹簧罩相对于推杆固定安装，弹簧设置在推杆轴与弹簧罩之间，所述弹簧通过推杆轴与弹簧罩形成压缩状态。
如上所述的用于刀具同步动作的运动机构，所述偏心旋转机构的转轴外周固定安装导套，导套与刀具组件配合。具体可以是刀具组件上安装导套滑槽，导套滑槽与转轴相对应，多个导套分别在多个导套滑槽内同步滑动，带动刀具组件同步上、下动作。
本发明还公开了一种切刀，包括如上任一所述的运动机构以及底盘、安装座、驱动机构、刀具组件，所述支架固定安装在安装座上，安装座下部与底盘固定，刀具组件与偏心旋转机构连接，驱动机构用于通过运动机构带动刀具组件上、下移动，通过调整偏心轮和/或传动机构中推杆轴的相对位置，可以实现刀具组件纵向两端高度位置变化。
如上所述的切刀，其特征在于，所述驱动部件包括手柄，手柄一端与其中纵向最外侧的一套摇杆机构上部固定连接，手柄的另一端为自由端，相对设置在纵向最外侧的另一套摇杆机构上方。
如上所述的切刀，所述安装座为一侧开口的U型构件，安装座在所述运动机构纵向两端对称设置有两套，所述底盘固定在两套安装座之间，支架固定在安装座的开口上侧。
如上所述的切刀，所述底盘上设有垫条和垫条夹板，垫条夹板通过连接件将垫条夹持在底盘上，所述垫条位于所述刀具组件的下方。
如上所述的切刀，所述底盘上设置有调整材料切割角度的小挡板组件。
与现有技术相比，本发明的有益效果：
1、本发明的运动机构以及切刀，改变了原有的手柄或电动装置与刀具成一体结构、刀具为铰接安装的方式，而是通过手柄或电动方式下压刀具组件整体，刀具组件受到的下压推力一致，本发明的偏心轮旋转机构与摇杆机构、传动机构配合，刀具组件安装在偏心轮旋转机构上，偏心旋转机构中设置有偏心轮以及与刀具组件连接的转轴，两点(不限于)同步带动刀具组件上、下运动，可以实现刀具组件的同步上、下动作，用于板材的切割处理。
2、和现有技术中通常利用偏心轮做机械动作往复运动不同，本发明中利用两个或多个偏心轮安装在支架上，通过推杆和推杆轴构成的传动机构或类似的连杆机构，保证每个偏心轮都能同步转动。而且，通过调整每一偏心轮的相对位置，可以实现刀具组件中刀刃在纵向前后端的高低调整，将其设置为前高后低或前低后高等方式，配合板材的厚度及特性要求，由于单位压力下切割面积降低，切割时更省力。
3、采用手动方式下，配置的手柄安装在其中一套摇杆机构上，增大力臂，带动偏心轮的动作。拉伸支撑杆不工作时，可收纳在底盘内或安装座上，减小机器的体积，方便携带；工作时拉出形成稳定的支撑。底盘支撑被切割的板材，其上安装有小挡板，通过调整板状放置方向和方式，调整角度实现斜角切割。安装座是一个U型构件，可以实现一定宽度板料的纵向切割。
4、垫条夹板把塑料垫条安装在底盘上，位于刀具组件的下方，在切割时保护刀刃。弹簧和弹簧罩的作用是防止刀刃在重力作用下自动下落。本发明不论采用电动还是手动操作方式，结构紧凑、体积小，方便搬运和携带；可以实现板材的倾斜、纵向切割等多种功能。本发明为刀具组件提供的冲击力小，解决 了传统切割易产生毛边、切割面不整齐的问题，切割效果好，切割更灵活，切割精度高；不会产生尘屑、板材崩飞等问题，解决环境和安全隐患。解决切割过程中对板材损害，保护切割安全，方便操作人员使用。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
为方便理解和描述本实施例，以图1所示左、右侧为纵向，对应表述为前端、后端，图1所示上、下为横向，对应表述为左侧、右侧。
如图1所示，本实施例公开的一种用于刀具同步动作的运动机构，包括摇杆机构、传动机构和偏心旋转机构，偏心旋转机构用于带动刀具组件1上、下移动，用于板材的切割加工处理。
本实施例中，摇杆机构、偏心旋转机构设置有两套，根据刀具组件1的纵向长度、或板材长度和宽度的切割需要，也可以设置两套以上的摇杆机构、偏心旋转机构，多套摇杆机构之间通过传动机构实现同步动作，每一摇杆结构与偏心旋转机构相对应并配合，从而保证准确、顺畅的同步动作。
如图1所示，偏心旋转机构包括偏心轮10和转轴8，转轴8穿过偏心轮10后与摇杆机构连接，偏心轮10安装在支架7上开设的支架孔内，偏心轮10与摇杆机构之间通过螺钉固定连接，偏心轮10通过摇杆机构的摆动带动下在支架孔内旋转，传动机构带动两套摇杆机构同步动作后，每一摇杆机构又同步带动偏心轮10和转轴8旋转，转轴8与刀具组件1配合，从而使刀具组件1形成上、下移动，完成板材切割切断。
具体而言，如图2所示，转轴8外周安装塑料导套9，导套9与固定在刀具组件1上的导套滑槽19配套，多个导套9分别在多个导套滑槽19内同步滑动，带动刀具组件同步上、下移动。
两套偏心轮10的形状和结构一致，并直接在支架7上开设与偏心轮10配合的安装口，支架7可以独立设置，或者作为本发明切刀中的与安装座配合的上梁架，横向上，该支架7设置有两套，刀具组件1设在两套支架7之间，用于保护刀具、设备安全和使用安全。
如图1、图5、图6所示，摇杆机构包括在支架7两侧对称设置的两套摇杆，两套摇杆分别为第一摇杆11、第二摇杆12，第一摇杆11、第二摇杆12横向上， 在两套支架7外侧分别对称设置有一块，由于第二摇杆12上部与作为驱动机构的手柄16连接，因此，第二摇杆12相对第一摇杆11较高，且为了使手柄16具有向上倾斜，其上部向纵向后侧弯曲，同时，为了保证摇杆与偏心轮10的连接稳定性，摇杆与偏心轮10之间设置有两套连接杆。
如图1、图3所示，传动机构安装在刀具组件1上方，包括推杆轴13、推杆14，由于摇杆机构与偏心轮旋转机构相配合，推杆轴13需要带动摇杆机构动作，因此，其数量与摇杆机构相同，推杆轴13与摇杆机构活动连接，推杆14与多套推杆轴13固定连接。
推杆14上安装弹簧15和弹簧罩17，弹簧罩17的下端与所述支架7固定，弹簧罩17相对与推杆14为固定安装，弹簧15位于弹簧罩17与纵向后端的推杆轴之间，弹簧15受弹簧罩17和其中一推杆轴13的作用处于压缩状态，通过弹簧罩17可以保持弹簧15对推杆14后侧具有一定的推力，保证手柄16自由回弹，避免刀具组件1的重力作用下自动下落，造成安全隐患。
也可以将弹簧罩17设置成纵向位置可调形式，以便在弹簧15老化或根据需要进行位置调整，弹簧罩17除具备上述的安全保护作用外，还可以作为手柄16下移的限位，以保护刀具组件1的刀刃等部件的质量。
为了保证刀具上、下动作的稳定性，在两套支架7的纵向前、后端分别设置端板20，端板20上开设滑槽21，刀具组件1端部固定的滑块22必须在滑槽21内限位滑动，因此，滑槽21的高度与刀具组件1上、下移动的幅度相配合。
本发明的运动机构，改变了原有的手柄16或电动装置与刀具成一体结构、刀具为铰接安装的方式，而是通过手柄16或电动方式下压刀具组件1整体，刀具组件1受到的下压推力一致，本发明的偏心轮旋转机构与摇杆机构、传动机 构配合，刀具组件1安装在偏心轮旋转机构上，偏心旋转机构中设置有转轴8和导套9连接偏心轮10和刀具组件1，两点(不限于)同步带动刀具组件1上、下运动，可以实现刀具组件1的同步上、下动作，用于板材的切割处理。
具体实施的选材和方式，以说明书附图作为图纸，按照说明书附图中各个部件的比例和配合方式实施，采用强力胶黏剂连接、焊接、铆接、法兰连接、一体成型式连接等常用的连接方式，实际制作时可以根据实际连接强度需要，无需创造性的选择对应的连接方式、连接点的厚度和强度。
本申请公开的一种切刀，包括如上所述的运动机构以及底盘2、安装座5、驱动机构、刀具组件1，支架7固定安装在安装座5上，安装座5下部与底盘2固定，刀具组件与偏心旋转机构连接，驱动机构用于通过连杆机构带动刀具组件上、下运动。驱动机构采用手柄6，为手动操作方式，驱动机构也可以设置为电动或液压驱动方式，但相对会增加重量和成本。
如图1、图3-图6所示，本实施例中的切刀，由运动机构、机体和刀具组件1三部分构成。
如图2所示，刀具组件1顶部带有导套滑槽19、最下端带有刀刃，导套滑槽19与转轴8和导套9配合。
机体包括底盘2、安装座5、拉伸支撑杆6以及和支架7，塑料垫条3和垫条夹板4，安装座5前后设置有两块、上梁左右设置有两件，用来支撑板材、运动机构和刀具组件1。
垫条夹板4把垫条3安装在底盘2上，位于刀体的下方，在切割时保护刀刃。拉伸支撑杆6不工作时，收缩在本切刀的内部以减小设备体积，方便携带；工作时拉出即可形成稳定的支撑。底盘2支撑被切割的板材，其上安装有小挡 板18，可以调整角度，用于斜角切割。安装座5是一个右侧开口的U型构件，以实现一定宽度板料的纵向切割。
运动机构，包括摇杆机构、传动机构和偏心旋转机构，偏心旋转机构用于带动刀具组件1上、下移动。纵向前后端各有2个对称设置的偏心轮10，分别安装在横向左右侧的2个支架7上，同时，每个偏心轮10的外侧与摇杆固定连接，通过第一摇杆11，第二摇杆12以及由推杆14、推杆轴13构成的的连杆机构实现每个偏心轮10都能同步转动。推杆轴13上设置的弹簧15和弹簧罩17，可以防止刀具组件受重力作用而自动下落，消除安全隐患。
通过调整偏心轮10和/或传动机构中推杆轴13的相对位置，可以实现刀具组件纵向两端高度位置变化。本实施例中，在左、右对称的第二摇杆12上，设置有三对高度不同调节孔，调节孔与第二摇杆12相对应的推杆轴配合，通过调整该推杆轴的位置，从而实现刀具组件纵向两端为水平、前高后低或前低后高这三种相对位置变化。通过调整偏心轮10实现刀具纵向两端高度位置变化，和上述方式类似。
和现有技术中通常利用偏心轮做机械动作往复运动不同，本发明中的偏心轮的作用是实现同步旋转和相对可以独立的位置调节，具体而言，通过推杆14和推杆轴13构成的传动机构或类似的连杆机构，使得每个偏心轮10都能同步转动。而且，通过调整每一偏心轮10的相对位置，可以实现刀具组件1中刀刃在纵向前后端的高低调整，将其设置为前高后低或前低后高等方式，配合板材的厚度及特性要求，相同的单位下压作用力下切割面积变小，切割时更省力。
本发明未详尽描述的技术内容均为公知技术。
