图2示出了根据本发明第一实施例中的内循环高速液压系统和动台板升降组件 的静止状态。该内循环高速液压系统包括液压缸组件和加压阀组件。
液压缸组件包括：高压油缸11、液压柱塞15以及壳体6。在高压油缸11的顶 部设置有一个轴向孔，该轴向孔与液压柱塞15顶部上方的腔体相通。在高压油缸11 的靠近顶部的位置还设置有至少一个径向油孔12，这些径向油孔12与所述轴向孔相 交。液压柱塞15在高压油缸11内作往复运动，液压柱塞15的下端可连接至动作元 件，在该较佳实施例中，动作元件是一个动台板16。壳体6包围高压油缸11并在其 外侧形成密封的内循环油腔，该内循环油腔可通过前述的至少一个径向油孔12与轴 向孔相通，进而可连通至液压柱塞15的顶部。另外，在壳体6的上部设置有压缩空 气入口7，用于引入压缩空气。
加压阀组件设置在液压缸组件的上方，该加压阀组件包括：加压伺服电机5和 加压柱塞10。加压柱塞10可由加压伺服电机5驱动而在设置于高压油缸11顶部的 轴向孔内上下移动。在该实施例中，在加压伺服电机5和加压柱塞10之间可设置有 驱动机构，该驱动机构包括：加压滚珠丝杆8和与加压滚珠丝杆8啮合而移动的加压 螺母9。加压滚珠丝杆8连接至加压伺服电机5并支承在轴承上旋转，加压螺母9连 接至加压柱塞10。
应该理解的是，如果需要，可采用由直线伺服电机5直接驱动加压柱塞10的方 式。
加压阀组件的作用如下。由加压伺服电机5，根据接收控制系统发来的指令，使 加压柱塞10适时关闭液压缸组件上的至少一个径向油孔12中的液压油，继而使加压 柱塞10进入液压柱塞15的顶部的高压油腔22。当加压柱塞10继续向下移动时，将 会压缩液压柱塞15顶部的低压液压油21，从而使密封腔内的压强增高，该压强最高 可达400kg/cm2，在液压柱塞15上产生巨大的推力。只要控制加压柱塞(1)向液压 柱塞15顶部的移动距离，即可控制液压柱塞15所产生的推力和高精度的位置，例如 可达到±0.01mm的位置重复精度。
图2中还示出动台板升降组件。该动台板升降组件连接至前述动台板16，动台 板升降组件包括：升降伺服电机20和升降机构。升降机构可由升降伺服电机20驱动 而使得动台板16按预设的升降曲线作升降运动。在该实施例中，升降机构包括：升 降滚珠丝杆18和与升降滚珠丝杆18啮合而移动的升降螺母19。升降滚珠丝杆18连 接至升降伺服电机20，而升降螺母19则连接至动台板16。
该动台板升降组件能够让动台板16快速、高精度的零速度接近并压紧固定平台， 同时拉动固定于动台板16上的液压柱塞15，使其上部的高压油缸11充液或向外泄 出液压油。
以下将结合图2-4来描述根据本发明较佳实施例的液压系统的动作过程。
在图2中，液压系统处于静止状态。在此状态下，低压压缩空气从压缩空气入 口7进入内循环油腔，使液压油21沿油流方向A，经过各径向油孔12进入液压柱塞 15的顶部，从而使液压柱塞15产生向下的低压推力。此时，动台板升降组件受到伺 服电机20所产生的原点静止时的静转矩的制约，从而对动台板16，进而对液压柱塞 15加以约束，于是停留在如图2所示的静止状态。此状态为本发明的液压系统的“原 点状态”。
参见图3，被低压压缩空气所推动的液压油21，经径向油孔12进入液压柱塞15 的顶部。此时，升降伺服电机20根据控制系统发出的指令而转动，使升降滚珠丝杆 18带动升降螺母19，进而推动与液压柱塞15相固定的动台板16以预设的下降曲线 向下朝向下固定平台17移动，无冲击地接近并压紧到下固定平台17。这样就完成了 “低压充液”的动作。随后，加压伺服电机5启动，驱动加压滚珠丝杆8旋转，使加 压螺母9推动加压柱塞10，向图中向下方向移动。在加压柱塞10的移动过程中，其 首先会将进入液压柱塞15顶部的径向油孔12关闭，从而在液压柱塞15顶部的上方 形成了一个密闭的“高压油缸”。当加压柱塞10继续向下移动时，密闭的高压油缸内 的液压油被压缩，从而使该高压油缸内产生很高的压强(例如400kg/cm2)，进而使 液压柱塞15产生很大的推力。只要改变加压伺服电机5的转动角度，就能改变加压 柱塞10的移动位置，相应也改变液压柱塞的推力或位置。
参见图4，当动台板16需要上升回归到图2中的静止状态时，加压伺服电机5 驱动加压滚珠丝杆8反转，于是加压螺母9会带动加压柱塞10向上移动。当加压柱 塞10移动至使径向油孔12开始暴露的位置时，前述“高压油缸”内的高压油，开始沿 油流方向B，向内循环油腔泄油。
此时，升降伺服电机20反转，带动动台板16和液压柱塞15一起向上移动，并 使液压油21经径向油12完全泄出。这样就完成了一个行程的全部动作，回归至图2 中的状态，并等待下一次动作指令的到来。
图5-7是根据本发明第一实施例的四个内循环高速液压系统(仅示出两个，两外 两个在图中被遮挡)构成的内循环高速液压平台处于各运行状态的剖视图。
除了内循环高速液压平台之外，图5-7中还示出了下固定平台17、右墙板14、 左墙板14A，其中上固定平台13、下固定平台17、右墙板14、左墙板14A共同组成 平台支承系统，该支承系统用于将内循环高速液压平台固定地安装到其所应用的设 备，诸如烫印机等。其中右墙板14和左墙板14A垂向连接在上固定平台13与下固 定平台17之间，从而将上固定平台13与下固定平台17的相对位置固定，并形成容 纳高压油腔22的壳体和动台板16并允许动台板16在其中往复运动的空间。此外， 液压缸组件的各壳体6通过螺栓、铆钉等固定连接到上固定平台13，而高压油腔22 的缸体容纳在形成于上固定平台13中的通孔内并同样也固定到上固定平台13。当然， 应理解液压缸组件的各壳体6或高压油腔22的缸体也可与上固定平台13一体形成。 通过以上述方式连接的内循环高速液压平台和支承系统，形成了作为整体的内循环高 速液压平台组件。这样形成的内循环高速液压平台组件结构紧凑，降低了组件的总体 高度，便于运输。
此外，图5-7中示出了内循环高速液压平台的控制系统。参照图5，本发明的控 制系统包括控制器1以及对应于动台板升降组件的伺服电机20的驱动器3以及对应 于各液压缸组件的伺服电机5的各驱动器(图中仅示出两个，即2和4)。该控制系 统用于按照动作要求，向各液压缸组件的加压阀组件的伺服电机5、动台板升降组件 的伺服电机20以及其它执行元件发出相应的指令并从其接收处理相关的反馈信息， 从而保证内循环高速液压动台的高速度，高压力，高精度的可靠工作。
接下来参照图5-7描述内循环高速液压平台在控制系统控制下的运行过程。
图5中示出各部件在平台开始下行时的状态：动台板16开始下压时，控制器1 按照预设的动作程序，向驱动器3发出驱动伺服电机20旋转的驱动指令，并带动升 降滚珠丝杆18旋转，从而使升降螺母19按照控制器1预设的加减速曲线，使动台板 16零速接近并压紧下固定平台17，即达到图6所示的状态。随着动台板16的下行， 压缩空气经各内循环高速液压系统的压缩空气入口7，压缩液压油21，使其经各油孔 12快速进入高压油缸11内，从而完成平台下行充液行程。
参照图6，当升降伺服电机20达到零速时，由驱动器3向控制器1发出到位信 号，同时控制器1向驱动器2、4发出各加压伺服电机5的同步旋转指令。此时，各 加压伺服电机5同步运行并分别带动各加压滚珠丝杠3，从而带动各加压螺母9做线 性移动并推动各加压柱塞10，首先封住各油孔12，同时压缩各高压油缸11中的液压 油，使其产生高的压强。应理解，使各加压伺服电机5伺步运行的方法可采用本领域 公知的任何方法，诸如并行控制、主从控制、交叉耦合控制、虚拟总轴控制、偏差耦 合控制等。
参照图7，当图6所示的全部动作完成后，控制器1首先向驱动器2、4发出旋 转指令，此时各加压伺服电机5同样按照控制器1预设的升降曲线旋转，并分别带动 各加压滚珠丝杆8，从而驱动各加压螺母9以带动各加压柱塞10作向上的线性移动。 当其移动到并停止在图7所示的位置时，控制器1即向驱动器3发出升降伺服电机 20旋转的指令。此时，该升降伺服电机20带动升降滚珠丝杆18，从而使升降螺母 19带动动台板16和液压柱塞15向上移动。此时，高压油缸11内的液压油2，经各 油孔12泄回内循环油腔内。此时完成了平台上下行行程的全部动作。
尽管参照包括4个内循环高速液压系统的内循环高速液压平台的第一实施例描 述了本发明，但本发明并不限于包括4个内循环高速液压系统，而是可包括1个以上 任何数量的内循环高速液压系统。
应理解，这里的控制器可以实施为本领域公知的控制器，诸如PLC、运动控制 器等。
本发明中的关于“上”、“下”的描述并不意味着限制附图中各部件在使用时 的方向。本领域的技术人员会理解，以上系统经改动也可倒置使用，如下文将描述的 本发明的第二实施例。
图8示出根据本发明第二实施例的内循环高速液压平台的立体图。该内循环高 速液压平台主要包括：下固定平台13′、动台板升降组件、安装到上固定平台13′的多 个(例如2个、3个、5个等，在该实施例中具体是4个)内循环高速液压系统、以 及控制系统(未示出)。其中动台板升降组件用于推动动台板16朝向上固定平台17′ 移动并以零速度与上固定平台17′接触(参见图9)。内循环高速液压系统用于在推 动动台板16朝向上固定平台17′移动时完成液压系统充液并在动台板16与

固定平 台17′接触后对上固定平台17′施加压力。控制系统用于按照动作要求，向各部件发出 相应的指令并接受处理相关的反馈信息，以保证内循环高速液压动台高速度、高压力、 高精度的可靠工作。
图9-11是根据本发明第一实施例的四个内循环高速液压系统(仅示出两个，两 外两个在图中被遮挡)构成的内循环高速液压平台处于各运行状态的剖视图。
在该实施例中，内循环高速液压平台包括4个相同的内循环高速液压系统。但 应理解，本发明并不限于此4个内循环高速液压系统，而是可包括诸如2个、3个等 任何合适的数量。这4个内循环高速液压系统具有与第一实施例类似的结构和运行过 程。在此参照图9仅对其中一个进行详细描述。
以图9左侧所示的液压缸组件为例，其包括：高压油缸11、液压柱塞15以及壳 体6。在高压油缸11的底部设置有一个轴向孔，该轴向孔与液压柱塞15底部下方的 腔体相通。在高压油缸11的靠近底部的位置还设置有至少一个径向油孔12，这些径 向油孔12与所述轴向孔相交。液压柱塞15在高压油缸11内作往复运动，液压柱塞 15的上端可连接至动作元件，在该较佳实施例中，动作元件是一个动台板16。壳体 6包围高压油缸11并在其外侧形成密封的内循环油腔，该内循环油腔可通过前述的 至少一个径向油孔12与轴向孔相通，进而可连通至液压柱塞15的底部。另外，在壳 体6的上部设置有压缩空气入口7，用于引入压缩空气。
加压阀组件设置在液压缸组件的下方，该加压阀组件包括：加压伺服电机5和 加压柱塞10。加压柱塞10可由加压伺服电机5驱动而在设置于高压油缸11底部的 轴向孔内上下移动。在该实施例中，在加压伺服电机5和加压柱塞10之间可设置有 驱动机构，该驱动机构包括：加压滚珠丝杆8和与加压滚珠丝杆8啮合而移动的加压 螺母9。加压滚珠丝杆8连接至加压伺服电机5并支承在轴承上旋转，加压螺母9连 接至加压柱塞10。
应该理解的是，如果需要，可采用由直线伺服电机5直接驱动加压柱塞10的方 式。
加压阀组件的作用如下。由加压伺服电机5，根据接收控制系统发来的指令，使 加压柱塞10适时关闭液压缸组件上的至少一个径向油孔12中的液压油，继而使加压 柱塞10进入液压柱塞15的底部的高压油腔22。当加压柱塞10继续向上移动时，将 会压缩液压柱塞15底部的低压液压油21，从而使密封腔内的压强增高，该压强最高 可达400kg/cm2，在液压柱塞15上产生巨大的推力。只要控制加压柱塞10向液压 柱塞15顶部的移动距离，即可控制液压柱塞15所产生的推力和高精度的位置，例如 可达到±0.01mm的位置重复精度。
图9中还示出动台板升降组件。该动台板升降组件连接至前述动台板16，动台 板升降组件包括：升降伺服电机20和升降机构。升降机构可由升降伺服电机20驱动 而使得动台板16按预设的升降曲线作升降运动。在该实施例中，升降机构包括：升 降滚珠丝杆18和与升降滚珠丝杆18啮合而移动的升降螺母19。升降滚珠丝杆18连 接至升降伺服电机20，而升降螺母19则连接至动台板16。
该动台板升降组件能够让动台板16快速、高精度的零速度接近并压紧固定平台， 同时拉动固定于动台板16上的液压柱塞15，使其上部的高压油缸11充液或向外泄 出液压油。
以下将结合图9-11来描述根据本发明较佳实施例的液压系统的动作过程。
在图9中，液压系统处于静止状态。在此状态下，低压压缩空气从压缩空气入 口7进入内循环油腔，使液压油21经过各径向油孔12进入液压柱塞15的底部，从 而使液压柱塞15产生向上的低压推力。此时，动台板升降组件受到伺服电机20所产 生的原点静止时的静转矩的制约，从而对动台板16，进而对液压柱塞15加以约束， 于是停留在如图9所示的静止状态。此状态为本发明的液压系统的“原点状态”。
参见图10，被低压压缩空气所推动的液压油21，经径向油孔12进入液压柱塞 15的底部。此时，升降伺服电机20根据控制系统发出的指令而转动，使升降滚珠丝 杆18带动升降螺母19，进而推动与液压柱塞15相固定的动台板16以预设的下降曲 线向上朝向上固定平台17′移动，无冲击地接近并压紧到下固定平台17′。这样就完成 了“低压充液”的动作。随后，加压伺服电机5启动，驱动加压滚珠丝杆8旋转，使 加压螺母9推动加压柱塞10，向图中向上方向移动。在加压柱塞10的移动过程中， 其首先会将进入液压柱塞15底部的径向油孔12关闭，从而在液压柱塞15底部的下 方形成了一个密闭的“高压油缸”。当加压柱塞10继续向上移动时，密闭的高压油缸 内的液压油被压缩，从而使该高压油缸内产生很高的压强(例如400kg/cm2)，进而 使液压柱塞15产生很大的推力。只要改变加压伺服电机5的转动角度，就能改变加 压柱塞10的移动位置，相应也改变液压柱塞的推力或位置。
参见图11，当动台板16需要下降回归到图9中的静止状态时，加压伺服电机5 驱动加压滚珠丝杆8反转，于是加压螺母9会带动加压柱塞10向下移动。当加压柱 塞10移动至使径向油孔12开始暴露的位置时，前述“高压油缸”内的高压油，开始向 内循环油腔泄油。
此时，升降伺服电机20反转，带动动台板16和液压柱塞15一起向下移动，并 使液压油21经径向油12完全泄出。这样就完成了一个行程的全部动作，回归至图9 中的状态，并等待下一次动作指令的到来。
除了内循环高速液压平台之外，图9-11中还示出了上固定平台17′、右墙板14、 左墙板14A，其中下固定平台13′、上固定平台17′、右墙板14、左墙板14A共同组 成平台支承系统，该支承系统用于将内循环高速液压平台固定地安装到其所应用的设 备，诸如烫印机等。其中右墙板14和左墙板14A垂向连接在下固定平台13′与上固定 平台17′之间，从而将下固定平台13′与上固定平台17′的相对位置固定，并形成容纳 高压油腔22的壳体和动台板16并允许动台板16在其中往复运动的空间。此外，液 压缸组件的各壳体6通过螺栓、铆钉等固定连接到下固定平台13′，而加压阀组件穿 过形成于下固定平台13′中的通孔内并同样也固定到下固定平台13′。当然，应理解液 压缸组件的各壳体6或高压油腔22的缸体也可与下固定平台13′一体形成。通过以上 述方式连接的内循环高速液压平台和支承系统，形成了作为整体的内循环高速液压平 台组件。这样形成的内循环高速液压平台组件结构紧凑，降低了组件的总体高度，便 于运输。
此外，图9-11中还示出了内循环高速液压平台的控制系统。参照图9，本发明 的控制系统包括控制器1以及对应于动台板升降组件的伺服电机20的驱动器3以及 对应于各液压缸组件的伺服电机5的各驱动器(图中仅示出两个，即2和4)。该控 制系统用于按照动作要求，向各液压缸组件的加压阀组件的伺服电机5动台板升降 组件的伺服电机20以及其它执行元件发出相应的指令并从其接收处理相关的反馈信 息，从而保证内循环高速液压动台的高速度，高压力，高精度的可靠工作。
接下来参照图9-11描述内循环高速液压平台在控制系统控制下的运行过程。
图9中示出各部件在平台开始上行时的状态；动台板16开始上压时，控制器1 按照预设的动作程序，向驱动器3发出驱动伺服电机20旋转的驱动指令，并带动升 降滚珠丝杆18旋转，从而使升降螺母19按照控制器1预设的加减速曲线，使动台板 16零速接近并压紧上固定平台17′，即达到图10所示的状态。随着动台板16的上行， 压缩空气经各内循环高速液压系统的压缩空气入口7，压缩液压油21，使其经各油孔 12快速进入高压油缸11内，从而完成平台上行充液行程。
参照图10，当升降伺服电机20达到零速时，由驱动器3向控制器1发出到位信 号，同时控制器1向驱动器2、4发出各加压伺服电机5的同步旋转指令。此时，各 加压伺服电机5同步运行并分别带动各加压滚珠丝杠3，从而带动各加压螺母9做线 性移动并推动各加压柱塞10，首先封住各油孔12，同时压缩各高压油缸11中的液压 油，使其产生高的压强。应理解，使各加压伺服电机5同步运行的方法可采用本领域 公知的任何方法，诸如并行控制、主从控制、交叉耦合控制、虚拟总轴控制、偏差耦 合控制等。
参照图11，当图10所示的全部动作完成后，控制器1首先向驱动器2、4发出 旋转指令，此时各加压伺服电机5同样按照控制器1预设的升降曲线旋转，并分别带 动各加压滚珠丝杆8，从而驱动各加压螺母9以带动各加压柱塞10作向下的线性移 动。当其移动到并停止在图11所示的位置时，控制器1即向驱动器3发出升降伺服 电机20旋转的指令。此时，该升降伺服电机20带动升降滚珠丝杆18，从而使升降 螺母19带动动台板16和液压柱塞15向下移动。此时，高压油缸11内的液压油21， 经各油孔12泄回内循环油腔内。此时完成了平台下行行程的全部动作。
尽管参照包括4个内循环高速液压系统的内循环高速液压平台的第二实施例描 述了本发明，但本发明并不限于包括4个内循环高速液压系统，而是可包括1个以上 任何数量的内循环高速液压系统。
应理解，这里的控制器可以实施为本领域公知的控制器，诸如PLC、运动控制 器等。
本发明中的关于“上”、“下”的描述并不意味着限制附图中各部件在使用时 的方向。
虽然以上结合较佳实施例对本发明进行了详细的描述，但应理解的是，熟悉本 技术领域的普通技术人员应该可以在上述揭示内容的基础上作出各种等同的变型和 改动而不偏离本发明的实质，因此，本发明的保护范围应由所附权利要求书来限定。
