一种螺栓筛选机
本申请要求于2018年07月13日提交中国专利局、申请号为201810770505.4、发明名称为“一种螺栓筛选机”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。

如图1所示，本发明的一种螺栓筛选机包括一外部框架10、一送料机构20以及一筛选机构30，所述外部框架10呈方形，所述送料机构20结合安装在所述外部框架10的顶部，所述筛选机构30结合安装在所述外部框架10内部。所述送料机构20与所述筛选机构30的入料部分对应设置，通过所述送料机构20能够将未经筛选的螺栓送入所述筛选机构30，所述筛选机构30能够将未经筛选的螺栓进行筛选排列后排出。所述筛选机构30采用螺旋滑道结构，螺栓在重力作用下在所述筛选机构30中从上向下滑动。所述筛选机构30在筛选过程中不断振动，有助于加快筛选过程。
具体的，如图2所示，所述送料机构20包括一送料支架21、一送料筒22、一送料滑道23以及一送料电磁铁组件24，所述送料支架21顶部具有一送料支撑板211，所述送料筒22底端垂直穿透所述送料支撑板211与所述送料支撑板211连接。所述送料筒22中存储未经筛选的螺栓。更进一步的，所述送料筒22底部设置若干定位插销221，所述定位插销221垂直于所述送料筒22侧壁与所述送料筒22可拆卸的连接，通过在所述送料筒22底部侧壁不同位置安装所述定位插销221，能够改变所述送料筒22的上下位置。所述送料滑道23设置在所述送料支撑板211底部，所述送料滑道23的一端与所述送料支架21可转动的连接，且所述送料滑道23在转动的过程中堵塞或开启所述送料筒22的底端。所述送料电磁铁组件24包括一第一送料电磁铁241和一第二送料电磁铁242，所述第一送料电磁铁241设置在所述送料支撑板211底部，所述第二送料电磁铁242设置在所述送料滑道23上，且所述第一送料电磁铁241与所述第二送料电磁铁242位置相对。当所述送料电磁铁组件24通电时，所述第一送料电磁铁241与所述 第二送料电磁铁242合并，所述送料滑道23在所述第二送料电磁铁242的带动下转动至与所述送料支撑板211贴合，堵塞所述送料筒22的底端，所述送料筒22中的螺栓无法进入所述筛选机构30；当所述送料电磁铁组件24断电时，所述第一送料电磁铁241与所述第二送料电磁铁242分开，所述送料滑道23在重力作用下转动，不再堵塞所述送料筒22的底端，所述送料筒22中的螺栓落至所述送料滑道23，并沿所述送料滑道23滑动落入所述筛选机构30。通过控制所述送料电磁铁组件24的通断电即可控制所述送料机构20开始或停止输送螺栓，操作便捷，所述送料机构20结构简单牢固，故障率低，便于检修维护。
如图3所示所述筛选机构30与所述外部框架10结合安装的后视图，所述筛选机构30设置在所述外部框架10内部，所述筛选机构30包括一基座31、一下底板32、一上顶板33、若干连接所述下底板32和所述上顶板33的滑道支撑架34、一直滑道35以及一螺旋滑道组件36。所述基座31与所述外部框架10底部固定连接，所述基座31顶部为一斜坡结构，所述下底板32与所述基座31顶部斜坡顶端可转动的连接。所述上顶板33与所述下底板32对位平行设置，且所述上顶板33设置接近所述外部框架10的顶部；若干所述滑道支撑架34互相平行，且若干所述滑道支撑架34均垂直于所述下底板32和所述上顶板33。当所述下底板32相对于所述基座31转动时，所述下底板32通过若干所述滑道支撑架34带动所述上顶板33同步转动。进一步的，所述上顶板33还包括一振动电磁铁组件331，所述振动电磁铁组件331与所述上顶板33及所述外部框架10顶端结合设置，通过控制所述振动电磁铁组件331的通断电，能够控制所述上顶板33与所述外部框架10顶端的相对距离，进而通过若干所述滑道支撑架34带动所述下底板32转动，即通过所述控制所述振动电磁铁组件331的通断电能够带动所述下底板32、所述上顶板33以及若干所述滑道支撑架34整体进行运动。通过不断的对所述振动电磁铁组件331进行通断电操作，即可控制下底板32、所述上顶板33以及若干所述滑道支撑架34整体产生振动。所述直滑道35与所述螺旋滑道组件36连接，且所述直滑道35及所述螺旋滑道组件36均与若干所述滑道支撑架34固定连接，所述直滑道35设置在接近所述上顶板33的位置，且所述直滑道35延伸超出所述上顶板33水平覆 盖范围，所述直滑道35延伸超出所述上顶板33水平覆盖范围部分与所述送料滑道23垂直对位，未经筛选的螺栓能够通过所述送料滑道23落入所述直滑道35中。当在所述振动电磁铁组件331作用下，所述下底板32、所述上顶板33以及若干所述滑道支撑架34整体产生振动时，所述直滑道35和所述螺旋滑道组件36也会随之产生振动，有利于加速螺栓在所述直滑道35和所述螺旋滑道组件36中的滑动速度，提高筛选效率。
如图4为所述基座31与所述下底板32结合安装的结构示意图，所述基座31顶部具有一斜坡311，所述斜坡311底端设置一弹簧片组312，所述斜坡311顶端具有一铰链组313，所述斜坡311顶部还均匀设置若干弹簧314，所述下底板32通过所述铰链组313与所述基座31可转动的连接，所述下底板32还通过所述弹簧片组312与所述基座31连接。所述弹簧片组312及所述弹簧314会在所述下底板32下落的过程中积蓄弹性势能，在所述下底板32上升的过程中进行释放，助力所述下底板32上升。所述弹簧片组312及所述弹簧314还会在所述下底板32下落的过程中降低冲击力度。
如图5所示为所述直滑道35的结构示意图，所述直滑道35底部具有一直滑槽351，所述直滑槽351沿所述直滑道35轴线设置，所述直滑道35内部具有若干挡料板352，所述挡料板352平行与所述直滑道35截面间隔连接设置于所述直滑道35中。落入所述直滑道35内的螺栓在滑过所述直滑道35的过程中受到所述挡料板352的阻挡分批次每次小量的进入所述螺旋滑道组件36，防止突然大量螺栓进入造成筛选出错的情况。所述直滑槽351的刻度针对目标螺栓设置，目标螺栓在滑动过程中会落入所述直滑槽351中，所述直滑槽351会卡住目标螺栓的头部，将其输送至所述螺旋滑道组件36中。
如图6所示为所述螺旋滑道组件36中一段螺旋滑道36A的结构示意图，螺旋滑道组件36可以根据需要筛选螺栓的种类或数量设置不同种类或数量的螺旋滑道，螺旋滑道依次上下设置，与若干所述滑道支撑架34固定连接。所述螺旋滑道36A包括一上滑道361A、一排料部362A以及一下滑道363A，所述上滑道361A、所述排料部362A以及所述下滑道363A呈螺旋形从上到下依次排列连接，需要筛选出的螺栓会在通过所述上滑道361A 滑动至所述排料部362A处排出，不需要筛选出的螺栓会继续通过所述下滑道363A向下滑动至另一段螺旋滑道36A或滑落至底部。所述上滑道361A顶端具有一上连接端3611A，且所述上滑道361A通过所述上连接端3611A与所述直滑道35连接，所述下滑道363A底端具有一下连接端3631A。所述上滑道361A底部具有一上滑槽3612A，所述上滑槽3612A与所述直滑槽351对接且宽度相同，需要筛选的螺栓会从所述直滑槽351划入所述上滑槽3612A；所述上滑槽3612A沿所述上滑道361螺旋方向延伸至所述排料部362A，需要筛选的螺栓会沿所述上滑槽3612A滑入所述排料部362A后排出。螺栓在所述上滑槽3612A中滑动的过程中，没有落入所述上滑槽3612A的需要筛选的螺栓会在振动的作用下落入所述上滑槽3612A，进而通过所述排料部362A排出。根据需要筛选螺栓的种类数量，所述螺旋滑道组件36能够设置由多段螺旋滑道组成，所述螺旋滑道36A的下连接端3631A能够与另一段螺旋滑道的上连接端连接，所连接的螺旋滑道具有宽度不同的上滑槽，从而能够筛选不同的螺栓。值得注意的是，从上往下的螺旋滑道的上滑槽的宽度呈递增分布。
如图7所示为所述螺旋滑道36A的所述排料部362A的结构示意图，所述排料部362A具有一排料槽3621A，所述排料槽3621A一端与所述上滑槽3612A对接，落入所述上滑槽3621A的螺栓会沿所述上滑槽3612A滑入所述排料槽3621A。所述排料槽3621A的另一端延伸至所述排料部362A的侧壁并穿透所述排料部362的侧壁，所述排料部362在所述排料槽3621A延伸出侧壁的位置具有一排料口3622A，所述排料口3622A呈直线延伸，所述排料口3622A能够卡住螺栓头部。螺栓沿所述排料槽3621A滑动冲入所述排料口3622A后继续运动，会在惯性作用下冲出所述排料口3622A，完成筛选过程。
