1-图 4所示， 本发明的缸盖自动锁紧装置， 设置在缸盖 1和缸体 2之间， 缸 盖 1上设置有沿圆周均匀分布的齿 12，缸体 2的上端设置有托住缸盖 1的卡箍 21， 卡 箍 21 具有容纳齿 12 的环槽和位于环槽上方的环形凸缘， 环形凸缘上设置有与齿 12 相配合的槽 213， 本发明还包括： 设置于缸盖 1的上方的吊臂 3， 吊臂 3的一端与缸盖 1的中心通过中心轴枢接， 另一端与卡箍 21枢接； 还包括驱动装置， 优选为锁紧气缸 4， 该驱动装置具有驱动端，驱动端连接到缸盖 1上偏离缸盖 1的中心轴线的位置以驱 动缸盖 1绕缸盖的中心轴线旋转， 以锁紧或解锁缸盖 1。 本发明的具体实施例如下： 实施例一： 本发明的缸盖自动锁紧装置， 包括缸盖 1和缸体 2， 缸盖 1上设置有沿圆周均匀 分布的齿 12， 缸体 2的上端圆周上设置有托住缸盖 1的卡箍 21， 卡箍 21具有容纳齿 12的环槽和位于环槽上方的环形凸缘，环形凸缘上设置有与齿 12相配合的槽 213，缸 盖 1的上方设置有吊臂 3， 吊臂 3的一端与缸盖 1的中心通过中心轴枢接， 另一端与 卡箍 21的外圆周枢接；吊臂 3上远离缸盖 1中心的位置上通过支座 9枢接有锁紧气缸 4， 锁紧气缸 4的内部设置有活塞杆， 活塞杆的一端连接有接杆 41， 接杆 41的一端伸 出锁紧气缸 4， 接杆 41伸出锁紧气缸 4的一端通过固定在缸盖 1上的连接耳 8枢接在 缸盖 1上， 由于连接耳 8的与接杆 41的枢接部距离缸盖 1有一定的距离， 因此能够托 起锁紧气缸 4， 以使锁紧气缸 4整体与缸盖 1分离， 进而防止了接杆 41与缸盖 1之间 的摩擦。 吊臂 3上远离缸盖 1中心的一端枢接有开盖气缸 5， 开盖气缸 5与缸体 2的缸壁 平行设置， 并且开盖气缸 5的中部与缸体 2固定连接， 以向吊臂 3施以向下的力进而 使缸盖 1沿垂直方向旋转， 打开缸盖 1， 为了增加开盖气缸 5的力， 开盖气缸 5还连 接有配重 7， 配重 7配合开盖气缸 5向吊臂 3施力。 本发明还包括控制系统， 控制系统与锁紧气缸 4电连接， 控制锁紧气缸 4的启动 与停止，控制系统与开盖气缸 5电连接，控制开盖气缸 5驱动吊臂 3沿垂直方向旋转。 本发明在使用时， 锁紧到位状态下， 齿 12与槽 213处于非配合位置， SP， 齿 12 位于卡箍 21上的相邻两槽 213之间的中间位置的下方，此时，缸盖 1无法沿垂直方向 旋转， 进而起到了阻止缸盖 1打开的作用。 在预进行解锁程序时， 控制系统向锁紧气 缸 4发出指令， 启动锁紧气缸 4， 活塞杆沿锁紧气缸 4向外运动， 进而带动接杆 41向 外运动推动缸盖 1绕其中心轴线旋转， 当旋转至齿 12与槽 213的配合位置时， SP， 齿 12位于槽 213内时， 即完成了缸盖 1与缸体 2的解锁， 解锁完成后， 控制系统向开盖 气缸 5发出指令， 开盖气缸 5向吊臂 3施力， 使吊臂 3拉动缸盖 1一起沿垂直方向上 旋转， 进而打开缸盖 1。 实施例二： 本发明的缸盖自动锁紧装置， 不但具有实施例一中的结构， 并且卡箍 21的外缘上 分别设置有解锁到位行程开关 212和锁紧到位行程开关 211，缸盖 1上设置有撞块 11， 撞块 11的一端固定在缸盖 1上， 另一端设置有撞头 111， 在缸盖 1与缸体 2闭合状态 下， 撞头 111位于解锁到位行程开关 212和锁紧到位行程开关 211之间， 并具有碰触 解锁到位行程开关 212的解锁到位状态和碰触锁紧到位行程开关 211的锁紧到位状态。 解锁到位行程开关 212与控制系统电连接，在解锁到位状态下，解锁到位行程开关 212 向控制系统发出解锁到位信号； 锁紧到位行程开关 211与控制系统电连接， 在锁紧到 位状态下， 锁紧到位行程开关 211 向控制系统发出锁紧到位信号。 为了增强信号的发 出功能， 锁紧气缸 4上还可以设置到位磁性感应装置， 在解锁到位状态下， 活塞杆带 动接杆 41伸出并触动到位磁性感应装置，此时， 到位磁性感应装置与解锁到位行程开 关 212各自向控制系统发出解锁到位信号，控制系统在接到到位磁性感应装置和 /或解 锁到位行程开关 212发出的解锁到位信号后， 控制锁紧气缸 4停止动作； 在锁紧到位 状态下， 活塞杆带动接杆 41缩回并触动到位磁性感应装置， 此时， 到位磁性感应装置 与锁紧到位行程开关 211各自向控制系统发出锁紧到位信号， 控制系统在接到到位磁 性感应装置和 /或锁紧到位行程开关 211发出的锁紧到位信号后， 控制锁紧气缸 4停止 动作。 本发明在使用时， 控制系统向锁紧气缸 4发出指令， 锁紧气缸 4启动， 当解锁到 位时， 撞块 11的撞头 111碰触解锁到位行程开关 212， 活塞杆带动接杆 41伸出， 触 动到位磁性感应装置， 到位磁性感应装置和解锁到位行程开关 212各自发出解锁到位 信号，控制系统在接到到位磁性感应装置和 /或解锁到位行程开关 212发出的解锁到位 信号后， 控制锁紧气缸 4停止供气， 至此解锁程序完成。 锁紧时， 自动控制系统发出 指令， 启动锁紧气缸 4， 当锁紧到位时， 撞头 111碰触锁紧到位行程开关 211， 活塞杆 带动接杆 41缩回并触动到位磁性感应装置，此时， 到位磁性感应装置和锁紧到位行程 开关 211各自发出锁紧到位信号， 控制系统在接到到位磁性感应装置和 /或锁紧到位行 程开关 211发出的锁紧到位信号后， 控制锁紧气缸 4停止供气， 至此锁紧程序完成。 实施例三： 本发明的缸盖自动锁紧装置， 与实施例二的区别在于， 还包括泄压装置， 泄压装 置与控制系统电连接， 控制缸盖 1打开前缸体 2内的最大压力值。 其中， 泄压装置优 选地包括： 与缸体 2内部连通的气动球阀 6以及设置于气动球阀 6上的安全手柄 61， 安全手柄 61与控制系统电连接，接受控制系统的指令进行旋转， 以使气动球阀 6与大 气相通或与大气隔绝， 安全手柄 61水平设置于气动球阀 6的上端， 安全手柄 61具有 位于缸盖 1上方的部位； 缸盖 1上设置有限位结构 13， 在缸盖 1锁紧到位状态下， 安 全手柄 61位于缸盖 1上方的部位抵住限位结构 13， 以防止缸盖 1的转动； 当安全手 柄 61旋转至气动球阀 6与大气相通时， 安全手柄 61位于缸盖 1的外缘的外侧并与限 位结构 13分离， 此时启动锁紧气缸 4， 缸盖 1可以沿其中心轴线旋转， 进而实现缸盖 1 的解锁， 本发明还包括压力检测装置， 该压力检测装置与控制系统电连接， 将其检 测到的缸体 2内部压力值反馈至控制系统。 本发明在使用时， 利用控制系统设置最高压力值为 0.2kg/cm2， 最高温度为 85 °C。 如图 1和图 2所示， 缸盖 1与缸体 2闭合状态下， 由于安全手柄 61抵住限位结构 13， 以使得缸盖 1无法进行旋转， 进而无法打开缸盖 1。 本装置预解锁时， 自动控制系统 首先发出指令， 旋转安全手柄 61， 使气动球阀 6与大气相通， 进行泄压， 此时， 安全 手柄 61位于缸盖 1的外缘的外侧并与限位结构 13分离。 当压力检测装置检测到缸体 2内气体压力降至 0.2kg/cm2以下时， 将压力值信息反馈给控制系统； 控制系统接到反 馈信号后， 启动锁紧气缸 4， 当开锁到位时， 如图 3和图 4所示， 撞头 111触动解锁 到位行程开关 212， 活塞杆带动接杆 41伸出并触动到位磁性感应装置， 此时， 到位磁 性感应装置和解锁到位行程开关 212各自发出解锁到位信号， 控制系统在接到到位磁 性感应装置和 /或解锁到位行程开关 212发出的解锁到位信号后，控制锁紧气缸 4停止 供气， 至此解锁程序完成。 锁紧时， 自动控制系统发出指令， 启动锁紧气缸 4， 当锁 紧到位时， 撞头 111触动锁紧到位行程开关 211， 活塞杆带动接杆 41缩回并触动到位 磁性感应装置， 此时， 到位磁性感应装置和锁紧到位行程开关 211各自发出锁紧到位 信号， 控制系统在接到到位磁性感应装置和 /或锁紧到位行程开关 211发出的锁紧到位 信号后， 控制锁紧气缸 4停止供气； 锁紧气缸 4停止供气后， 控制系统向安全手柄 61 发出指令， 旋转安全手柄 61， 至安全手柄 61抵住限位结构 13， 防止缸盖 1的旋转， 至此锁紧程序完成。 本发明由于限位块的阻挡作用， 开锁时只有先打开安全手柄 61泄压的情况下，锁 紧气缸 4才能运行， 这样就起到了安全保护作用。 本装置安全可靠， 生产制造机械化 和自动化水平高， 省时省力， 劳动效率高。 本发明还提供了一种筒子纱染色机， 具有缸盖 1和缸体 2， 缸盖 1与缸体 2之间 设置有缸盖自动锁紧装置， 其中， 缸盖自动锁紧装置为上述的缸盖自动锁紧装置。 从以上的描述中， 可以看出， 本发明的缸盖自动锁紧装置及包括该装置的筒子纱 染色机， 通过在缸盖 1与缸体 2之间设置驱动装置， 通过驱动装置的驱动端驱动缸盖 1绕缸盖 1的中心轴线旋转， 以锁紧或解锁缸盖 1。本发明利用驱动装置的驱动作用取 代了人工旋转缸盖 1， 不仅操作力大， 而且可一次连续旋转到位； 可节省劳动力， 提 高生产效率， 大大降低劳动力成本， 大大提高了设备的机械化和自动化水平， 有利于 实现自动化生产。 本发明的缸盖自动锁紧装置除了适用于纺织染整设备行业外， 还可以适用于其他 装置的缸盖 1锁紧或解锁， 只要能够实现缸盖 1的自动锁紧或解锁即可。 以上所述仅为本发明的优选实施例而已， 并不用于限制本发明， 对于本领域的技 术人员来说， 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内， 所作的 任何修改、 等同替换、 改进等， 均应包含在本发明的保护范围之内。
