AI Technical Summary
Technical Problem
In the existing technology, the disassembly efficiency of interference fit bushings is low and there are safety hazards, making it difficult to meet the replacement requirements of tamping devices under high-frequency vibration environments.
Method used
The device employs a combination of bushing bracket, connecting rod, clamping assembly, and hydraulic power unit. The hydraulic cylinder drives the grippers to open and clamp the bushing, and the elastic reset element enables the grippers to automatically close. The hydraulic power unit then pulls out the bushing.
Benefits of technology
It enables labor-saving, efficient, and safe bushing removal, avoids workpiece damage, and improves work efficiency and safety.

Abstract
本申请公开了一种过盈安装衬套的拆卸装置及方法，拆卸装置包括衬套支架；连接杆，其与第一液压油缸远离所述连接杆的一端连接，另一端与第二液压油缸的缸体连接；夹持组件，其包括两片夹爪以及弹性复位元件；夹爪用于伸入待拆卸的衬套孔内并撑开卡住衬套；液压动力单元包括两个液压输出设备，二者分别连接第一液压油缸和第二液压油缸；第一液压油缸被配置为其活动端伸出顶推衬套支架的第二端的端面，通过连接杆带动第二液压油缸及夹持组件移动，以拉拔出衬套。本申请通过设置衬套支架作为固定支撑点，并利用两个独立控制的液压油缸分别驱动夹爪撑开卡紧衬套及整体拉拔衬套，达到了省力、高效、安全且操作便捷的拆卸效果，同时避免了工件损伤。
