Description

千斤顶揿手自动焊接装置 技术领域
本发明属于焊接机械技术领域，具体涉及一种千斤顶揿手自动焊接装置，用于对成型后的千斤顶揿手的封口部位的焊接。
背景技术
前述千斤顶揿手的形状可通过对中国专利授权公告号CN3081843D的阅读可知，前述千斤顶揿手的封口部位即为该专利的仰视图的左端揭示的一条槽口。为了体现良好的观瞻性，目前，前述千斤顶揿手的封口部位普遍以图弧替代直角。也就是说先前的千斤顶揿手的封口部位的形状呈L字形或称阿拉伯数字的7字形，该形状的长处是：便于进行封口焊接；不足是：因封口处存在直角过渡而有失柔和性并且影响观瞻效果。由圆弧代替前述形状可显著增进观瞻性，但是给封口焊接带来麻烦，也就是说增加了焊接难度。
目前，对前述成型后的千斤顶揿手的封口部位的焊接工作由手工完成，手工焊接的不言而喻的欠缺至少有以下几个方面：一是工人的焊接作业强度大；二是焊接效率低下，需投入众多人力(具有焊接技能的工人)以满足工业化批量生产要求；三是焊接的规整性或称一致性效果难以保证，因为人工焊接往往与焊接工人的经验、责任心乃至情绪诸因素相关；四是因焊接是由工人手执焊枪进行的，在焊接过程中需定睛观察焊位，因而不能佩戴如二氧化碳气体焊时那样的防护罩，于是对焊接人员的眼睛刺激大；五是由于对千斤顶掀手的焊前定位也需由焊接工人手动操作完成，因而进一步增大了焊接工人的作业强度并且降低了焊接效率。
在公开的中国专利文献中可见诸对千斤顶零部件焊接的相关装置的技术信息，典型的如发明专利授权公告号CN102294565B推荐的“千斤顶支架焊接装置”，通过对该专利说明书的全文阅读可以确定：对于旨在设计千斤顶揿手自动焊接装置在技术层面上具有可借鉴性，具体表现为左右、前后以及上下位移机构(以下相应地称“横向、纵向以及上下螺杆传动机构”)的宏观结构可以袭用，但是，由于千斤顶揿手与千斤顶支架在彼此的形状、构造等方面有着本质的差异，因而该专利未给出以下几个方面的技术启示：其一，依据说明书第0032段的描述，由于夹装千斤顶支架是以手动方式进行的，因而焊接工人的作业强度相对较大并且对焊接效率产生相应的影响，又由于千斤顶揿手的形状怪异并且体积较小，因而如果实施手工夹装，那么所耗时间会显著长于对千斤顶支架的夹装，而且夹装的可靠性难以保障，而自动地对千斤顶揿手夹装并定位是减轻焊接工人作 业强度以及提高焊接效率的不可偏废的一个重要因素；其二，如前述，由于千斤顶揿手的封口部位呈圆弧状，因而若要使焊枪对其焊接，那么需使焊枪顺应圆弧状的角度回转，而前述专利在将连接件与千斤顶支架焊接时，焊枪表现为前后上下的直线状位移，也就是说焊枪前后上下位移动作相对于焊枪焊圆弧动作要简单得多；其三，只有使有待于焊接的千斤顶揿手自动地抵达焊接工位，才能体现真正意义上的自动化并且得以保障自动焊接效率。由于并非限于前述几个方面的因素，因而对于设计出结构合理的并且满足对千斤顶掀手自动化焊接要求的装置有必要融入新的设计元素，下面将要介绍的技术方案便是在这种背景下产生的。

当由待焊千斤顶揿手自动引入机构5将有待于焊接的千斤顶揿手20(图1虚线示意)引入千斤顶揿手接应机构2的千斤顶揿手容纳腔24内后，侧向定位作用缸32工作，侧向定位作用缸柱321向缸体外伸展，经侧向定位作用缸柱让位孔221伸入到千斤顶揿手容纳腔24对千斤顶揿手20的后侧偏上部施加顶推力，将千斤顶揿手20限定在千斤顶揿手容纳腔24内，使千斤顶揿手20的开口部位即封口部位201变小形成一缝隙，焊接后形成一焊缝，反之亦然。与此同时，下面将要提及的千斤顶揿手端面定位机构4也工作，对千斤顶揿手20的右端端面限定，反之亦然。
前述的千斤顶揿手端面定位机构4包括一拖板作用缸固定座41、一拖板作用缸42、一拖板43、一对拖板导杆44、一揿手端面迫持头45和一位置信号采集器46，拖板作用缸固定座41的左端与前述机架工作台11固定，而右端探出前述机架1的右侧，拖板作用缸42在对应于拖板作用缸固定座41的右端前侧的位置与拖板作用缸固定座41固定，拖板43的中部对应于拖板作用缸42的前侧，在该拖板43的左端构成有一端面迫持头固定板431，而在拖板43的右端构成有一作用缸柱连接板432，该作用缸柱连接板432与前述拖板作用缸42的右端端面并行并且该拖板作用缸42的拖板作用缸柱421的末端与作用缸柱连接板432连接，进而由旋配在拖板作用缸柱421的末端的作用缸柱限定螺母4211限定，一对拖板导杆44彼此上下并行并且分别对应于拖板作用缸柱421的上下侧，该对拖板导杆44的左端与拖板作用缸42的拖板作用缸缸体滑动配合，而右端优选以焊接方式与作用缸柱连接板432固定，揿手端面迫持头45在对应于前述千斤顶揿手容纳腔24的右端的位置固定在迫持头螺杆451上，而该迫持头螺杆451通过迫持头螺杆螺母4511固定在端面迫持头固定板431上，位置信号采集器46在对应于揿手端面迫持头45的后侧的位置固定在前述端面迫持头固定板431上。作为优选的方案，将前述千斤顶揿手侧向定位机构3的结构体系的侧向定位作用缸固定座31与拖板作用缸固定座41的左端上部固定。

前述侧向定位作用缸32工作的同时，拖板作用缸42也工作，具体是：当拖板作用缸柱421向缸体内即向左位移时，由拖板作用缸柱421通过作用缸柱连接板432带动拖板43向左位移，使固定于端面迫持头固定板431上的揿手端面迫持头45向左位移并抵靠于千斤顶揿手20的右端端面，此时由位置信号采集器46采集信号并反馈给前述的电气控制箱30，拖板作用缸42不再使拖板作用缸柱421继续向左位移。反之同例。
继续见图1，前述的待焊千斤顶揿手自动引入机构5包括一揿手导入槽51、一振动器52、一导入槽倾斜度调整作用缸53和一倾斜度调整作用缸柱调整导板54，揿手导入槽51自左端向右端倾斜，该揿手导入槽51的右端端面同时与前述前定位座21的左端端面以及后定位座22的左端端面固定并且揿手导入槽51的右端还同时与前述的挡板23固定，揿手导入槽51的导入槽槽腔511与前述千斤顶揿手容纳腔24相对应并且相通，振动器52以悬置状态固定在揿手导入槽51的右端底部，倾斜度调整作用缸柱调整导板54优选以焊接方式固定在揿手导入槽51的底部，在该倾斜度调整作用缸柱调整导板54上开设有一调整槽541，导入槽倾斜度调整作用缸53通过作用缸座532与前述前定位座21的左端端面铰接，该导入槽倾斜度调整作用缸53的导入槽倾斜度调整作用缸柱531的末端在对应于调整槽541的位置通过销轴5311与倾斜度调整作用缸柱调整导板54连接，并且由旋配在销轴5311上的销轴螺母53111限定。在本实施例中，前述的导入槽倾斜度调整作用缸53为气缸，具体如同对侧向定位作用缸32的说明；前述的振动器52为直线振动器。
在实际的使用状态下，前述揿手导入槽51的左端即图示状态高的一端与振动盘相接合，由振动盘将有待于焊接的千斤顶揿手20有序地引至导入槽槽腔511，进而由振动器52(直线振动器)振动导入前述的千斤顶揿手容纳槽24。由于振动盘属于现有技术，因而申请人不再展开说明。此外，前述揿手导入槽51的左端的位置调整由前述的导入槽倾斜度调整作用缸53的状态决定，具体而言，导入槽倾斜度调整作有缸柱531向缸体外伸展的程度越大，则揿手导入槽51的左端越向上，即倾斜程度越大，反之同例。
继续见图1，前述的纵向螺杆传动机构6包括一纵向传动箱61、一纵向螺杆驱动电机62和一纵向螺杆63，纵向传动箱61以水平卧置状态固定在前述托架12的顶部，在 该纵向传动箱61的长度方向的上部固定有一纵向导轨板611，纵向螺杆驱动电机62与纵向传动箱61的左端端面固定，纵向螺杆63位于纵向传动箱61内，该纵向螺杆63的左端与纵向螺杆驱动电机62传动连接，而右端转动地支承在纵向传动箱61的右端的纵向螺杆支承板612上，并且在纵向螺杆63上配设有一纵向螺杆传动螺母631.
由图1所示，前述的横向螺杆传动机构7连同前述的上下螺杆传动机构8与前述纵向导轨板611滑动配合并且还同时与前述纵向螺杆传动螺母631固定连接；前述的纵向螺杆驱动电机62为具有正反转功能的伺服电机；前述的焊枪角度回转机构9与上下螺杆传动机构8的右侧固定；前述的焊枪10固定在焊枪固定座101上，而该焊枪固定座101与焊枪角度回转机构9固定。
当受控于电气控制箱30的纵向螺杆驱动电机62工作时，由其带动纵向螺杆63转动，由纵向螺杆63带动纵向螺杆传动螺母631在纵向螺杆63上位移，由纵向螺杆传动螺母631的位移而带动下面即将描述的横向螺杆传动机构7连同上下螺杆传动机构8相应位移，纵向螺杆传动螺母631向左或向右位移取决于纵向螺杆63的转动方向，而纵向螺杆63的转动方向取决于纵向螺杆驱动电机62正转或反转该两种工作状态的变化。
继续见图1，前述的横向螺杆传动机构7包括一横向传动箱71、一横向螺杆驱动电机72和一横向螺杆73，在横向传动箱71的后端朝向下的一侧各通过导座固定螺钉7111固定有一对横向传动箱滑动导座711，该对横向传动箱滑动导座711彼此前后对应并且在分别与前述纵向导轨板611的前后侧滑动配合的同时还与前述的纵向螺杆传动螺母631固定连接，在横向传动箱71的长度方向的上部固定有一横向导轨板712，横向螺杆驱动电机72与横向传动箱71的后端端面固定，横向螺杆73位于横向传动箱71内，该横向螺杆73的后端与横向螺杆驱动电机72传动连接，而前端转动地支承在横向传动箱71的前端端面的横向传动螺杆支承板713上，并且在横向螺杆73上配设有一横向螺杆传动螺母731。在本实施例中，前述横向螺杆驱动电机72为具有正反转功能的伺服电机。
由图1所示，前述的上下螺杆传动机构8连同前述的焊枪角度回转机构9与前述的横向导轨板712滑动配合并且同时与前述的横向螺杆传动螺母731固定连接。固定在前述焊枪固定座101上的前述焊枪10为二氧化碳气体保护焊枪。
由于前述的一对横向传动箱滑动导座711与纵向导轨板611滑动配合并且同时与纵向导杆传动螺母63固定连接，因而整个横向螺杆传动机构7可相对于纵向螺杆传动机构6左右移动。
当受控于电气控制箱30的横向螺杆驱动电机72工作时，由其带动横向螺杆73转动，由横向螺杆73带动横向螺杆传动螺母731在横向螺杆73上位移，由横向螺杆传动螺母731的位移而带动下面即将描述的上下螺杆传动机构8连同焊枪角度回转机构9相应位移，横向螺杆传动螺母731向前或向后位移取决于横向螺杆73的转动方向，而横向螺杆73的转动方向取决于横向螺杆驱动电机72正转或反转该两种工作状态的变化。
继续见图1，前述的上下螺杆传动机构8包括一上下传动箱81、一上下螺杆驱动电机82、一上下螺杆83和一滑动导座84，滑动导座84与前述的横向导轨板712滑动配合，在该滑动导座84朝向上下传动箱81的一侧(即图示状态的右侧)构成有一上下滑动导向板841，在上下传动箱81的高度方向的左侧固定有一竖向导轨板811，上下螺杆驱动电机82固定在上下传动箱81的顶部，上下螺杆83的上端与上下螺杆驱动电机82传动连接，而下端转动地支承在上下传动箱81的上下螺杆支承板812上，并且在该上下螺杆83上配设有一上下螺杆传动螺母831，前述的上下滑动导向板841与前述的竖向导轨板811滑动配合并且还同时与前述上下螺杆传动螺母831固定。在本实施例中，前述的上下螺杆驱动电机82为具有正反转功能的伺服电机。
由图1所示，前述的焊枪角度回转机构9连同所述的焊枪固定座101与所述上下传动箱81的右侧下部固定。
当受控于电气控制箱30的上下螺杆驱动电机82工作时，由其带动上下螺杆83转动，由于前述的上下螺杆滑动导向板841是与上下螺杆传动螺母831固定的，因而在上下螺杆83转动时，该上下螺杆传动螺母831不会上下移动，从而迫使整个上下传动箱81连同上下螺杆驱动电机82携下面将要描述的焊枪角度回转机构9向上或向下位移，向上或向下位移取决于上下螺杆83的转动方向，而上下螺杆83的转动方式取决于上下螺杆驱动电机82正转或反转该两种工作状态的变化。
通过上述说明并且由图1的示意可知，前述的纵向传动箱61、横向传动箱71以及上下传动箱81三者形成了三座标即X、Y和Z三个方向的位置关系。
继续见图1，前述的焊枪角度回转机构9包括一焊枪角度回转驱动电机91、一减速箱92和一减速箱固定座93，减速箱固定座93通过减速箱固定座螺钉932与减速箱固定座过渡板931固定，而该减速箱固定座过渡板931通过过渡板固定螺钉9311与前述上下传动箱81的右侧下部固定，焊枪角度回转驱动电机91与减速箱92传动配合并且由减速箱92连同焊枪角度回转驱动电机91固定在减速箱固定座93上，该减速箱92的减速箱 动力输出轴921伸展到减速箱固定座93的前方，前述的焊枪固定座101与该减速箱动力输出轴921固定。
当受控于前述电气控制箱30的焊枪角度回转驱动电机91工作时，由其带动减速箱92，由减速箱92减速并且由减速箱动力输出轴921带动焊枪固定座101转动，由于焊枪10固定在焊枪固定座101上，因而焊枪10也随焊枪固定座101转动。焊枪10的头部对应于前述千斤顶揿手20的封口部位201。
通过申请人在上面所作的说明并且依据专业常识，前述的侧向定位作用缸32、拖板作用缸42、位置信号采集器46、振动器52、纵向螺杆驱动电机62、横向螺杆驱动电机72、上下螺杆驱动电机82以及焊枪角度回转驱动电机91均与电气控制箱30电气控制连接，即受控于电气控制箱30的PLC(可编程序控制器)。
请参见图2并且结合图1，在图2中详细示出了千斤顶揿手20，并且还示出了对该千斤顶揿手20的封口部位201完成了二氧化碳气体保护焊焊接的情形。由此可知，前述的焊枪10为二氧化碳气体保护焊焊枪，但并不受此限定。
申请人结合图1和图2简述本发明的使用，由图中未示出的振动盘将有待于焊接的千斤顶揿手20供给揿手导入槽51，抵达揿手导入槽51的揿手20循着导入槽槽腔511滑落到千斤顶揿手接应机构2的结构体系的千斤顶揿手容纳腔24。接着前述的千斤顶揿手侧向定位机构3以及千斤顶揿手端面定位机构4工作，按申请人在上面所述而将千斤顶揿手20定位在千斤顶揿手容纳腔24内，其状态由图1所示。接着由焊枪角度回转机构9的焊枪角度回转驱动电机91的工作而使焊枪固定座101连同焊枪10作圆弧转动，由焊枪10对封口部位201实施焊接。在焊枪10对封口部位201进行焊接的过程中，通过前述纵向螺杆传动机构6、横向螺杆传动机构7以及上下螺杆传动机构8的协同作用而确保焊枪10准确地对封口部位201实施焊接。焊接完成后，前述的相应机构反向动作，由在线焊接工使完成了封口焊接的千斤顶揿手20逐离并使其循着配接于机架1的下方的导出槽导出。
综上所述，本发明提供的技术方案弥补了已有技术中的缺憾，顺利地完成了发明任务，如实地兑现了申请人在上面的技术效果栏中载述的技术效果。
