本发明属于冲床技术领域，特别涉及一种冲床冲切导向定位装置。
背景技术
目前，金属工件加工是机械加工行业中一个重要的工序，现有的加工程序包括磨削、打磨、冲切等环节，其中，冲切是比较重要的一个部分，冲切是指将工件冲切出所需要形状的过程，因此冲切是应用较为广泛的加工方法，其实利用冲头下压会对工件产生作用力，以对工件的表面进行加工。
金属工件在冲切加工过程之前需要先将其传送至冲头冲切处，传送的过程中可能会出现工件偏移的情况，因此需要对工件进行导向，避免其偏移；金属工件在冲切加工过程中需要对工件进行定位固定，防止其歪斜以保证冲切位置的准确；同时现有技术中的金属工件冲切前对其进行调整和导向以及最终的冲切定位分别通过不同的设备进行，没有将调整、导向和冲切集成为一体，增加工作人员的劳动强度。
通过检索现有技术，检索到如下相关专利：
中国发明专利，公开号为CN102975230A，一种冲床冲切导向定位冶具及方法，包括第一限位块:所述第一限位块固定于冲床的工作台面上，并靠于冲切材料侧边缘；通过第一限位块的作用,将连续通过冲床工作台面的冲切材料的位置限定使其按预定位置通过工作台面,避免冲切材料跑偏,为冲切材料提供导向和定位。但是待冲切的金属工件往往大小和形状不一致，需要不断的根据进入设备中的金属工件的大小调整第一限位块；现有技术中的治具还包括固定于冲床工作台面上的支架，所述第一限位块连接支架，并通过支架固定于冲床的工作台面上。所述支架上设有固定杆，该固定杆位于冲切材料上方，并与工作台面之间留有供冲切材料通过的空隙。除了在冲切材料的幅宽方向限定外，还通过固定杆在冲切材料上方限制，使其在竖直方向上也只能贴于工作台面。在金属工件传送过程中，固定杆仅能在金属工件经过其下方时对其进行限位。但是在金属工件传送至与固定杆错位时，固定杆无法再对金属工件传送过程中进行竖 直方向和水平方向上的限位。

具体实施方式
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，所描述的实施例仅仅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。
如图1-图10所示，一种冲床冲切导向定位装置，设置在工作台40处，工作台40一端设置有冲切工位1，冲切工位1上方设置有冲头2，工作台40中部沿其长度方向固定设置有第一传送带3和第二传送带41，第一传送带3和第二传送带41分别位于冲切工位1的左右两侧；
该导向定位装置包括调整组件、导向压紧组件和冲切定位组件，所述工作台40前后两侧分别开设有与第一传送带3的传送方向相垂直的第一通孔4，所述调整组件在第一通孔4内前后移动；
工作台40是由前后两块竖直板和上下两块水平板形成的折形结构，第一通孔4和第二通孔5设置在上方的水平板上，竖直板不会对调整组件以及导向压紧组件产生干涉。
所述工作台40中部的前后两侧开设有与第一传送带3的传送方向相平行的第二通孔5，所述导向压紧组件在第二通孔5左右移动，当所述导向压紧组件与第一传送带3同步向冲头方向移动时，所述导向压紧组件压紧金属工件的顶面和侧面；
所述冲切定位组件包括转动设置在工作台40前后两侧的第一定位压板6和第二定位压板7，所述第一定位压板6和第二定位压板7底部之间转动设置有转动板8，所述工作台40底部铰接设置有驱动油缸9，所述驱动油缸9的活动端与转动板8转动连接，当所述冲头2冲切时，所述第一定位压板6和第二定位压板7压紧金属工件的顶面。
待冲切的金属工件通过第一传送带3进行传送，当金属工件到达调整组件处时，调整组件在第一通孔4内向第一传送带3中心位置处移动，当调整组件在第一通孔4内移动至与金属工件侧面接触的位置并与金属工件侧面接触时，通过调整组件的移动推动金属工件位置移动，实现金属工件位置的调整，校直后的金属工件随着第一传送带3传送至导向压紧组件处，通过导向压紧组件将其压紧在第一传送带3上，避免调整组件调整后的金属工件出现偏移的情况，同时导向压紧组件与第一传送带3同步移动，将金属工件输送至冲切工位1处，冲切定位组件在冲切工位1处转动将金属工件压紧，避免冲头2冲切金属工件时，金属工件出现晃动偏移的情况，此过程将金属工件的调整、传送和定位集成为一体，提高了金属工件冲切时的工作效率。
工作台40内固定设置有第一电机10，第一电机10的活动端固定设置有双头螺杆11，双头螺杆11的每段螺纹处均螺纹连接有第一底座12，调整组件设置在第一底座12上，调整组件包括第二电机13，第二电机13与第一底座12固定连接，第二电机13的转轴上固定设置有偏心轴14，偏心轴14背离第二电机13的一端固定设置有校直块15，偏心轴14活动设置在第一通孔4内即在第一通孔4内前后移动，校直块15位于第一传送带3侧面，第二电机13转轴转动带动双头螺杆11转动，由于双头螺杆11的每段螺纹上分别螺纹连接有第一底座12，因此第一底座12的数量是两个，调整组件也设置有两个且分别固定在第一底座12上，在第一电机10转动驱动双头螺杆11转动时，双头螺杆11上的两个第一底座12相对移动或者相背移动，金属工件到达调节组件处时，两个第一底座12相对移动，驱动每个第一底座12上固定的调整组件相对移动，此时偏心轴14在第一通孔4内朝着第一传送带3中心处移动，当校直块15随着偏心轴14的移动到达金属工件处时，第二电机13转动带动偏心轴14转动，偏心轴14转动带动校直块15在第一传送带3两侧移动至与金属工件侧面相抵的位 置处，当两个校直块15均与金属工件侧面相抵时，金属工件位置变换至与两个校直块15表面贴合的位置处，通过金属工件侧面与两个校直块15侧面相抵实现将金属工件位置调整，因此通过两个校直块15位置的变换实现金属工件的调整过程，此过程中对金属工件位置的调整是第二电机13驱动偏心轴14运动，偏心轴14带动两校直块15运动与金属工件的前后侧面接触，将金属工件推动至完全位于两校直块15之间，在对金属工件的位置调整完成后，两个第一底座12相背移动，驱动每个第一底座12上固定的调整组件相背移动，此时偏心轴14在第一通孔4内朝着背离第一传送带3中心的方向移动，金属工件达到导向压紧组件处，被导向压紧组件压紧。
调整组件的调节过程包括两步：第一步双头螺杆11上的两个第一底座12相对移动后，对不同宽度的调整组件进行调整可以适应不同宽度的金属工件，增加调整组件的通用性；第二步是偏心轴14转动使得金属工件侧面与两个校直块15的侧面相抵，使校直块15对金属工件位置进行微调。以方形金属工件为例，仅通过第一步调节之后，可能存在金属工件的两个对角被压紧的情况，而大多数情况需要将方形金属工件调整至其侧面与第一传送带3侧面平行的位置，因此通过校直块15与金属工件的接触，校直块15在偏心轴14的带动下运动推动金属工件移动至与第一传送带3平行的位置，实现金属工件的微调。
校直块15与第一传送带3相对的一侧开设有凹槽16，凹槽16内设置有辊筒17，辊筒17的上下两端分别与凹槽16的上下侧壁转动配合，辊筒17位于第一传送带3上方，在校直块15与金属工件侧表面接触对其进行调整时，由于第一传送带3持续移动，因此金属工件随之移动，通过辊筒17对其进行辅助传送，避免校直块15对金属工件进行校直时，金属工件卡在两个校直块15之间。
工作台40内固定设置有第三电机18，第三电机18的转轴上固定设置有驱动螺杆19，驱动螺杆19的表面螺纹连接有第二底座20，工作台40的底部滑动设置有驱动箱21，驱动箱21的顶部(即驱动箱21与工作台40底部的相对面)固定设置有滑块，工作台40底面固定设置有导轨(即工作台40与驱动箱21的相对面)，滑块滑动设置在导轨上，通过滑块与导轨的滑动配合实现导向压紧组件在工作台40内左右移动的过程，导向压紧组件包括固定设置在第二底座20上的驱动气缸22，驱动气缸22的活动端固定设置有驱动块23，驱动块23的上 部活动设置在驱动箱21内，驱动块23顶部的前后两侧分别固定设置有连接块24，前后两个连接块24均位于驱动箱21内，每个连接块24背离驱动块23的一端分别铰接设置有卡钳25，卡钳25的顶部穿出第二通孔5设置，卡钳25在第二通孔5内左右移动。
驱动箱21顶部的前后两侧分别开设有与卡钳25相对应的活动孔26，卡钳25穿出活动孔26设置，活动孔26内固定设置有圆柱状的第一限位杆27和第二限位杆28，第一限位杆27靠近驱动箱21中心设置，第二限位杆28背离驱动箱21中心设置，卡钳25靠近驱动箱21中部的一侧设置有斜面29，斜面29与第一限位杆27相抵，卡钳25背离驱动箱21的一侧设置有凹陷30，第二限位杆28活动设置在凹陷30内，在卡钳25转动过程中，第二限位杆28在卡钳25侧面的凹陷30内转动，通过第二限位杆28和第一限位杆27的设置，避免卡钳25转动到极限位置时造成损伤，同时卡钳25转动过程通过第二限位杆28在凹陷30内转动辅助实现。
第三电机18转动带动驱动螺杆19转动，驱动螺杆19转动带动第二底座20在工作台40内左右移动，第二底座20左右移动带动驱动气缸22及与驱动气缸22连接的部件左右移动，驱动气缸22活动端带动驱动块23以及驱动块23上安装的连接块24在驱动箱21内上下移动，当调整组件调整后的金属工件到达导向压紧组件处时，驱动气缸22活动端收缩，带动驱动块23及前后两个连接块24在驱动箱21内向下移动，此时第一限位杆27和第二限位杆28与卡钳25的配合处向上移动，前后两个卡钳25在前后两个第二通孔5内向下移动，卡钳25向下移动的过程中与金属工件上表面接触将其压紧在第一传送带3上，第一传动带3向右移动传送金属工件时，第二底座20在驱动螺杆19的驱动作用下同步向右移动，带动卡钳25在第二通孔5内向右移动，实现金属工件传送过程中的压紧过程。
卡钳25的顶部垂直且固定设置有压紧块31，压紧块31活动设置在第一传送带3上方，通过压紧块31随着卡钳25的升降实现对金属工件的压紧或松开的过程，当金属工件压紧传送至冲切工位处时，卡钳25松开金属工件并在第二通孔5内向下移动，通过驱动螺杆19的转动第二底座20向左移动，带动卡钳25在第二通孔5内向左移动至调整组件处，再次对另一金属工件进行压紧，金 属工件传送过程中，卡钳25将金属工件的侧面压紧，卡钳25上固定的压紧块31与金属工件的顶面相抵，将金属工件在竖直方向上压紧在第一传送带3上，由于导向压紧组件与第一传送带同步向冲切工位1处移动，因此导向压紧组件会一直将金属工件压紧在第一传送带3表面，随着金属工件向冲切工位1处移动，金属工件在水平和竖直方向上均被压紧限位，避免其出现偏移的情况。
驱动油缸9的底部铰接设置有安装座32，安装座32固定设置在工作台40内，转动板8的前侧面呈三角形状，转动板8的竖截面也为三角形状，转动板8其中一个拐角的一侧转动设置有卡扣33，卡扣33与驱动油缸9的活动端固定连接，工作台40内固定设置有竖板34，转动板8的中部垂直且固定设置有转轴35，转轴35背离转动板8的一端与竖板34转动连接。转动板8的另外两个拐角处分别转动设置有第一连杆36和第二连杆37，第一连杆36和第二连杆37均左右间隔设置有两个，第一定位压板6左右间隔设置有两个，第一连杆36的顶端与第一定位压板6转动连接，两个第一定位压板6分别位于冲切工位1的左右两侧，第二定位压板7左右间隔设置有两个，第二连杆37的顶端与第二定位压板7转动连接，两个第二定位压板7分别位于冲切工位1的左右两侧。工作台40的前侧固定设置有与第一定位压板6相对应的第一铰接座38，第一定位压板6的中部与第一铰接座38铰接，工作台40的后侧固定设置有与第二定位压板7相对应的第二铰接座39，第二定位压板7的中部与第二铰接座39铰接。
金属工件传送至冲切工位1处时，驱动油缸9的伸缩端伸出驱动转动板8在竖板34处转动，此过程中驱动油缸9的一端在安装座32处转动，另一端带动卡扣33在转动板8处转动，在转动板8转动的过程中，转动板8另外两个拐角处的第一连杆36和第二连杆37转动，同步带动第一定位压板6和第二定位压板7转动，此过程中第一定位压板6的中部和第二定位压板7的中部在第一铰接座38和第二铰接座39处转动，第一定位压板6和第二定位压板7在工作台40前后两侧转动，对进入到冲切工位1的工件进行竖直方向的压紧，避免冲头2冲切时金属工件出现晃动的情况。在冲头2冲切金属工件后与金属工件分离时，金属工件与冲头2之间可能会出现相对静止情况，此时由于第一定位压板6和第二定位压板7对金属工件在竖直方向上的压紧限位，避免出现上述情况时，金属工件随着冲头而移动。通过第一定位压板6在第一铰接座38处转动、 第二定位压板7在第二铰接座39处转动，这一步不仅实现金属工件竖直方向上的压紧，更能实现对金属工件水平方向上的压紧。
以板状的金属工件为例，本装置的工作原理是：金属工件进入到第一传送带3时，随着第一传送带3的移动，金属工件到达校直块15处，第一电机10驱动第一底座12移动，使两个偏心轴14上固定安装的两个校直块15在第一通孔4内相对移动至金属工件处，第二电机13驱动偏心轴14转动，偏心轴14带动校直块15侧面与金属工件侧面接触，通过两个校直块15同步作用，实现金属工件的校直过程即金属工件侧面与第一传送带3侧面平齐，随着第一传送带3的持续移动，校直块15侧面的辊筒17的转动辅助对金属工件进行传送，此过程既能实现金属工件的校直调整又将其传送至导向压紧组件处；当金属工件到达导向压紧组件位置处，第三电机18驱动螺杆19转动，第二底座20随着螺杆转动在工作台40内移动，驱动气缸22的活动端带动驱动块23及固定在驱动块23上的连接块24在驱动箱21内上下移动，连接块24上下移动过程中带动前后两个卡钳25在连接块24端部转动，卡钳25顶部的压紧块31随着卡钳25的转动将金属工件压紧或者放松，当卡钳25顶部的转动至压紧块31与金属工件表面接触时，将其压紧在第一传送带3上，第一传送带3移动的同时，第二底座20在螺杆上与第一传送带3同步向右移动，实现金属工件夹紧并传送的过程，将其传送至冲切定位组件处；到金属工件到达冲切工位1时，驱动油缸9的伸缩端伸出驱动转动板8在竖板34处转动，转动板8另外两个拐角处的第一连杆36和第二连杆37转动，同步带动第一定位压板6和第二定位压板7转动，此过程中第一安装板的中部和第二安装板的中部在第一铰接座38和第二铰接座39处转动，第一安装板和第二安装板在工作台40前后两侧转动，对进入到冲切工位1的工件进行压紧，避免冲头2冲切时金属工件出现晃动的情况。
以上仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
