Description

一种伺服液压机
技术领域：
本实用新型主要涉及锻压行业的液压机领域，尤其涉及一种伺服液压机。
背景技术：
目前的液压机主要采用异步电机驱动，存在着效率低、噪音大等缺点。
实用新型内容：
本实用新型目的就是为了弥补已有技术的缺陷，提供一种伺服液压机，它采用伺服电机控制液压泵的运转，具有效率高和噪音小的优点。
本实用新型是通过以下技术方案实现的：
一种伺服液压机，包括有供水槽、液压缸和控制阀组，所述控制阀组的出油口和调节口均通过管路分别接入液压缸的进油端和回油端，控制阀组的进油管路和回油管路均伸入供水槽内，所述液压缸的活塞端部固定连接有滑块，其特征在于：所述控制阀组的进油管路上安装有液压泵和伺服电机，所述伺服电机控制液压泵运转。
所述的一种伺服液压机，其特征在于：所述控制阀组上安装有压力传感器。
本实用新型时采用伺服电机驱动液压泵，液压泵驱动液压缸的液压机。它通过改变伺服电机的转速对滑块的行程进行控制。通过压力传感器检测传动介质(液压油)的压力，通过软件或硬件计算计算改变伺服电机的转速闭环控制传动介质的压力，从而控制液压缸的输出力。
本专利采用伺服电机直接驱动液压泵具有以下优点：
(1)所述滑块不工作时，伺服电机不转动，具有节能和降噪的作用。
(2)采用伺服电机调节滑块的速度，使加速减速更柔性，具有提高效率的作用。
(3)用伺服电机保压，具有压力稳定，节能等特点。
(4)使滑块的速度可控。
附图说明：
图1为本实用新型的结构示意图。
具体实施方式：
一种伺服液压机，包括有供水槽7、液压缸4和控制阀组3，所述控制阀组3的出油口和调节口均通过管路分别接入液压缸4的进油端和回油端，控制阀组3的进油管路和回油管路均伸入供水槽7内，所述液压缸4的活塞端部固定连接有滑块5，控制阀组3的进油管路上安装有液压泵2和伺服电机1，所述伺服电机1控制液压泵2运转。控制阀组3上安装有压力传感器6。
