为了进一歩地优化本发明的实施效果， 本发明所涉及的具有改进 型传动结构的轮胎后充气装置的第二种实施方式中， 如图 2所示， 上 述的第二卡盘 5上相对于其卡盘端的另一端固定连接气缸的活塞籽， 即第二卡盘 5的卡盘座 51 固定连接气缸 6的活塞軒 61， 同时第二卡 盘 5套设于导杆 63上。 为了保证轮胎与卡盘之间可以形成密闭空间， 设置气缸可以推动第二卡盘继续运动一段距离， 从^有效地去除两个 卡盘之间在达到预设距离后所具有的间隙。
为了进一步地优化本发明的实施效果， 本发明所涉及的具有改进 型传动结构的轮胎后充气装置的第三种实施方式中， 如图 2所示， 上 述的气缸 6沿第二卡盘 5的边缘均布有多个， 可以更为稳固地驱动第 二卡盘的运_动。
为了进一步地优化本发明的实施效果， 本发明所涉及的具有改进 型卡盘结构的轮胎后充气装置的第四种实施方式中， 如图 1所示， 上 述的具有改进型传动结构的轮胎后充气装置还包括相对于水平方向 而对称于上述第一、 第二卡盘 2、 5的第三、 第四卡盘 7、 8， 该第三 卡盘 7的结构同于该第一卡盘 2 , 该第四卡盘 8的结构同于该第二卡 盘 5， 从而形成上下两个可以独立运行的工位。
为了进一步地优化本发明的实施效果， 本发明所涉及的具有改进 型卡盘结构的轮胎后充气装置的第六种实施方式中， 如图 1所示， 上 述的机架 1上还设置有相对于垂直方向而对称于上述第一、 第二、 第 三和第四卡盘 2、 5、 7和 8的另一套卡盘机构 9， 从而形成四个可以 独立运行的工位。
下面介绍本发明的工作过程： 结合图 1 -5所示， 卸胎机械手将疏 化好的轮胎从疏化机抓到第一卡盘 2上后， 电机 4开始工作， 第二链 轮 34和第一链轮 33带动螺母 32旋转， 螺杆 31上升， 第一- 盘 2和 轮胎一起迅速提升到指定高度 （可设定） ， 此时上下两卡盘之间的间 距达到预设高度值， 为了保证轮胎和上下卡盘之间形成密闭空间， 气 缸 6推动第二卡盘 5向下运动一段距离， 此时开始对轮胎内部进行预 定型充气， 随着轮胎内部空间里的蒸气压力逐渐增加， 轮胎对上下卡 盘的反作用力逐渐加强， 由于第一- 盘 2是螺杆 31 带动上升下降， 自锁性能良好，第一卡盘 2保持不动， 而第二卡盘 5是由气缸 6推出， 其竖直位置相对可变， 当轮胎内部压力大于气缸 6工作压力时， 轮胎 便会推动第二卡盘 5运动， 直到第二卡盘 5回到原位， 此时， 两卡盘 回到原始设定值， 轮胎开始正常充气冷却， 充气完成后，
