中心配重块与至少两块周向配重块;
其中,中心配重块下压于中心保压杆653的顶端使得中心保压杆653下压于工件69的中心区域;每块周向配重块下压于相应一块周向保压块顶端使得周向保压块下压于工件69的周向区域;具体地,周向保压块设有两组,且关于中心保压杆653对称布置。
相较于现有的保压机构,整体的压头结构,本发明中的采用中心保压杆653及周向保压块对工件69上的不同的区域进行保压,分区块保压,简化了单个保压头的形状,便于加工成型保压头,同时,由于保压头在压合过程中同样受到工件对其的反作用力,保压头长期使用容易产生磨损,尤其是,保压头上部分细长的凸出部,容易产生折断,现有一体的保压头出现损坏时,需要全部替换,而在本发明中,仅需替换破损的中心保压杆653或周向保压块,节约成本。
在一具体实施例中,参考图8-10中详细示出了,工件69包括基座691及装配在基座691上的装配零件692,基座691上设置有环形凸块6911,装配零件692装配在环形凸块6911,装配零件692包括:零件本体6923,其一面与基座691贴合;另一面与压头相压合,且其上设有,外缘凸部6921,其为设置在零件本体6923部分边缘位置处的连续凸起;以及,中心凹部6922, 其为设置在零件本体6923中心位置处向内凹陷的槽口;
参照图5、6可以注意到,周向保压块包括第一保压块651及第二保压块652,第一保压块651与第二保压块652拼合形成的外缘轮廓对应装配零件692的外缘,且当第一保压块651与第二保压块652拼合后的整体其内部形成中空的压杆腔655,中心保压杆653设置在压杆腔655内;
第二保压块652压合面的一端上设置有凸起的第一压块6521及第二压块6522;第一压块6521及第二压块6522压合零件本体6923上的不同位置,使得第一压块6521、第二压块6522间相对凹陷的部分形成让位空间,从而避开零件本体6923上部分区域;
第一保压块651压合面的一端上设置有凸部压块6511,凸部压块6511沿第一保压块651的外缘设置,凸部压块6511的位置对应第一压块6521、第二压块6522;
周向保压块上设置凸起的凸块以使得压合部分的周向区域,从而避开了设置在周向区域内的精密部件,保证了保压质量。
同时,中心配重块与周向配重块对应设置在中心保压杆653及周向保压块上,使得中心保压杆653及周向保压块上的压力可独立调整以便于中心保压杆653及周向保压块上配置的配重块6562满足工件69不同区域下对保压压力的需求。
中心配重块与中心保压杆653构成中心保压组件,每一块周向配重块与相应一块周向保压块构成相应一组周向保压组件,中心保压组件的重量与任意一组周向保压组件的重量均不相同。
根据上述方案采用的一种配重块分配具体实施例中,中心配重块的重量与任意一块周向配重块的重量均不相同。中心区域与周向区域所需的保压压力不相同;
更进一步地是,任意两块周向配重块的重量均不相同,周向区域上所需的保压压力均不相同,以便于保压压力满足不同区域的不同需求。
再次参照图1-3所示,该保压机构还包括保压支撑架6581,保压支撑架6581的顶部开设有贯穿其上下表面的保压通孔65811,保压支撑架6581中设有位于保压通孔65811的正下方的顶推组件68,待保压的工件69在顶推组 件68的顶推下推向保压支撑架6581的顶部并使得工件69的待保压区域在保压通孔65811中露出;
保压支撑架6581承接整个保压机构的零部件,顶推组件68将工件69顶升实施保压,该保压机构可架设于传输流水线上,便于流水线作业,实现自动化。
进一步地,保压支撑架6581上固接有架设于保压通孔65811上方的保压导向组件659;
中心保压杆653及周向保压块受保压导向组件659限定方向;
顶推组件68顶升工件69,使得中心保压杆653及周向保压块受保压导向组件659限定方向向上滑动。
保压导向组件659及保压支撑架6581依次上下布置形成压头支座658,压头支座658用于盛放该保压机构内的零部件,具体地,顶推组件68安装在保压支撑架6581内,压头设置在保压导向组件659安装的结构空间内。
保压导向组件659包括两块导向立板,两块导向立板平行且间隔设置以形成位于两者之间的导向空间,中心配重块及周向配重块设于导向空间中并且均与导向立板的内侧沿竖直方向滑动连接。
中心配重块包括:中心配重支撑架,其由中心保压杆653所支撑并且与导向立板的内侧滑动配接;以及,至少一块中心配重砝码,其设于所述中心配重支撑架上;
周向配重块包括:周向配重支撑架,其由周向保压块所支撑并且与导向立板的内侧滑动配接;以及,至少一块周向配重砝码,其设于周向配重支撑架上。
现在将参考图4所示,其中更详细地示出了中心配重支撑架以及周向配重支撑架的结构相同为图中的承压板656;中心配重砝码及周向配重砝码为图中的配重块6562;
在一优选实施例中,承压板656安装有载重导柱6561,配重块6562套设在载重导柱6561上,通过载重导柱6561限制配重块6562的位置,使得配重块6562盛放在承压板656上;
保压导向组件659包括导向部及导轨部,保压导向组件659的导向部与 承压板656连接,导轨部设置在保压支撑架6581上,通过导向部与导轨部滑动连接,限制承压板656的移动方向。
中心配重块与保压支撑架6581的顶部之间弹性连接中心复位部件,周向配重块与保压支撑架6581的顶部之间弹性连接有周向复位部件。中心复位部件能够发生弹性变形,中心复位部件作用于中心配重块使得中心配重块沿竖直方向的下压保压力能够得到缓冲,防止在保压过程中由于保压力的突增造成工件的损坏。
其中地,中心复位部件及周向复位部件包括缓冲块6573,在一优选实施例中,缓冲块6573为弹簧;保压支撑架6581内架设限位块657;限位块657内置有缓冲块6573;缓冲块6573用于承接承压板656,使得在承压板656在下压时,采用缓冲块6573进行缓冲,保护自重保压机构内部的零部件;
参考图7所示,限位块657呈工形,限位块657包括下横梁6571及上横梁6572,下横梁6571及上横梁6572通过一支撑柱连接形成限位块657的支撑结构,限位块657安装在下横梁6571、上横梁6572;
中心保压杆653及周向保压块上的承压板656承接在下横梁6571、上横梁6572上的限位块657,减小了限位块657的占地面积,从而减小了机构面积,使得结构更加紧凑。
周向保压块上的承压板656与中心保压杆653上的承压板656错位设置,现参考图4,中心保压杆653上的承压板656设置凸起于周向保压块上的承压板656,使得中心保压杆653上的承压板656高起于周向保压块上的承压板656,通过错位设置,中心保压杆653上的承压板656的投影落在周向保压块上的承压板656上,且其间并无干涉,可正常进行保压工作,同时,减小了结构的占地面积,其结构更加紧凑。
参考图5所示,保压支撑架6581的顶部设置有校正板654,周向保压块压合在校正板654上,校正板654用于等效替代工件69的高度,在保压工作前,用来做压印试验。
通过压头压合在校正板654上,验证压头的压力否均匀,不能把压力试纸直接接放在产品上。校正板654目的就是构造一个等效替换面试验压印是否满足工件69压合需求,从而保证工件69保压的精确性。
周向保压块的顶部设置有向外侧延伸的裙边,以用于稳定承接承压板656,校正板654上设置有凹槽,两周向保压块上的承接板拼接形成的承接部与凹槽形状一致,使得两周向保压块上的承接板盛放在凹槽内。
保压支撑架6581的顶部靠近顶推组件68的一侧上安装有定位杆6582,基座691盛放在料盘694内,料盘694上开设有于定位杆6582相对应的定位孔6941,通过顶推组件68将料盘694顶升至定位杆6582与定位孔6941连接,从而对料盘694内的基座691定位,从而使得压头精确地压合在所需压合的区域上。
顶推组件68包括推板682及驱动推板682的抬升气缸681,通过抬升气缸681推动推板682,使得推板682承接基座691,为了推板682准确地连接基座691,推板682上设置有推起块,基座691的底部设置有限位槽6542,通过推起块伸入限位槽6542内,从而限制基座691的位置。
同时,本发明提供的保压机构,为了实现调整工件部分的形状还应包括供电装置、移载设备、以及检测控制系统,相应动作机构都应具有相应的动力机构等,相应机构所具有的有益效果,不再赘述。
尽管本发明的实施方案已公开如上,但其并不仅仅限于说明书和实施方式中所列运用,它完全可以被适用于各种适合本发明的领域,对于熟悉本领域的人员而言,可容易地实现另外的修改,因此在不背离权利要求及等同范围所限定的一般概念下,本发明并不限于特定的细节。
