Description

传动链悬吊模壳止旋装置 技术领域
本发明涉及一种传动链悬吊物止旋装置，具体地讲，本发明涉及一种精密铸造干燥生产中的传动链悬吊模壳止旋装置，该技术方案属于机械传输技术领域。
背景技术
精密铸造工艺中的制壳工序属重点工序，其实质是一种循序渐成形过程，它由多道挂浆工序和相应的干燥处理工序组成，因此用于制壳的工时相对较多，正常情况下占该零件坯件制作工时的80％左右。本行业为了提高生产效率，通常在实施模壳每道挂浆工序之后的干燥处理工序上作技术改进，当今较理想的办法是将刚完成挂浆的模壳悬挂到传动链上，随传动链匀速送进干燥房内烘干。此技术方案经实践证明有效，能够显著提高模壳干燥效率。但是，此技术方案存在的问题是干燥质量欠佳，特别是模壳的迎风面与背风面干燥程度有差异。为此，本行业对该技术方案又作了进一步改进，其技术措施在行走的模壳上增加旋转运动，模壳动态位移可以克服干燥不均的问题。可是，该技术改进又带来新的技术难题，就是动态的模壳位置不确定性较大，模壳下线时增加配套机械手定位摘取难度。
发明内容
本发明主要针对动态的模壳下线时，配套机械手定位摘取难的问题，提出一种传动链悬吊模壳止旋装置。该装置设在传动链的末端且位于配套机械手一侧，这种机械式定点止旋结构简单、使用便捷、安装可靠。
本发明通过下述技术方案实现技术目标。
传动链悬吊模壳止旋装置，它包括柱桩、轨道、基座、制动杆、传感器和挂具。所述轨道为槽钢制成开口朝下的条形轨，水平横置的轨道 作定位安装。所述基座为片状构件，板面上均布两只朝下的矩形缺口，每只缺口内配装一只挂具，基座借助内置挂具的转轮悬吊在轨道中，挂具和所挂的模壳一并相对于基座旋转，横向顺序串连接的基座构成链式传动结构。其改进之处在于：所述制动杆为两端设有朝外折弯角的细长杆件，杆长L＝600～1500mm，折弯长度l＝100～150mm，夹角α为锐角，水平横置的制动杆安置在轨道靠近配套的机械手一侧，其高度位置处在基座中部并与轨道相平行，两端折弯段朝外安置，构成一种两端均留敞口式导向制动结构。所述传感器为定位传感器，安装位置在基座居中靠上边沿处，感应区面对配套的机械手。所述柱桩为朝下垂挂的柔性杆件，其固定端安装位置在轨道卸载区前端，即制动杆前敞口端口部。
作为进一步改进方案，所述制动杆两端折弯的锐角相等，其锐角α＝20°～40，优选30°。
作为进一步改进方案，所述柱桩为一节圆柱形弹簧，优选圆柱形压缩弹簧。
本发明与现有技术相比，具有以下积极效果：
1、在轨道一侧安置一道相平行的制动杆，此种由制动杆对挂具旋转约束结构很简单、制作容易、使用便捷、止旋效果好；
2、在烘干线卸载区进口端安置的柱桩为一节富有柔性的弹簧，充分利用柱桩的柔性来吸收进入卸载区的挂具旋转能量，由于该处的挂具首先得到柱桩有效缓冲，便于之后的制动杆快速、可靠止旋；
3、柔性柱桩与制动杆配合限制挂具，除止旋效果好，而且大大减小运行噪声，直接改善生产区的环境。
附图说明
图1是本发明结构示意图，该结构位于烘干生产线卸载区。
图2是图1的侧视图。
图3是图1的俯视图。
具体实施方式
下面根据附图并结合实施例，对本发明作进一步说明。
附图所示的传动链悬吊模壳止旋装置，它包括柱桩1、轨道2、基座3、制动杆4、传感器5和挂具6。所述轨道2为槽钢制成开口朝下的条形轨，其走向布置满足干燥工艺及配套的干燥房。水平横置的轨道2既有直线段，也有圆弧弯，图1仅是烘干生产线卸载区的一段结构示意图。所述基座3为片状构件，是挂具6的载体。基座3借助内置挂具6的转轮6.1悬吊在轨道之中，内置的挂具6和所挂的模壳7一并相对于基座3旋转。本发明中的基座3采用横向顺序串连接，由此形成链式传动结构，为持续生产创造条件。在干燥过程中挂具6旋转，可克服挂具6悬吊模壳7干燥不匀的问题。但是，进入卸载区的挂具6和悬吊的模壳7在惯性的作用下仍然处于旋转状态，使得配套的机械手8得到不到待卸载模壳7的准确位置信号，不能准确摘取已干燥的模壳7。为了解决摘取难题，本发明在轨道2前侧面对配套的机械手8处，配置相平行的制动杆4。如图2所示，制动杆4为两端设有朝外的折弯角的细长杆件，本实施例杆长L＝850mm，折弯l＝100mm，两端折弯的锐角相等，优选锐角α＝30°。安装制动杆4时将两端折弯段朝外安置，这样就构成一种两端均留敞口式导向制动结构，便于随挂具6导入的模壳7止旋。为了便于配套的机械手8准确地摘取已完成干燥处理且止旋的模壳7，在基座3的板面上配装传感器5，以备配套机械手8定位摘取。本实施例所用传感器5是一种定位传感器，直接安装在基座3居中靠上边沿处，感应区面对配套的机械手8。所述柱桩1为下垂挂的柔性杆件，它固定端安装位置处在轨道2卸载区前端，即制动杆4前敞口端口部。本实施例中的柱桩1是一节圆柱形压缩弹簧，具有足够的弹性和柔性，在结构中对传输的挂具6起到缓冲作用，一方面减少随挂具6导入的模壳7止旋前的冲击力，有利于减小后续制动杆4的止旋负荷，平移的挂具6易实现快速定位，便于配套的机械手8快速并准确摘取挂具6吊挂的模壳7。因此，本发明实际使用时，除显著提高卸载效率外，还减少运动噪声，改善工作环境。
