Abstract

本实用新型公开了一种工程机械维修工具领域的伸缩式加力套筒,以解决目前小型工程机械维修空间小,使用现有普通工具不便把持,零部件紧固后拧紧力矩达不到工艺要求的问题。它由外筒和内筒套叠而成,外筒右半部开有凹槽,凹槽中设有稳定销,凹槽右边的外筒端部表面开有槽口,内筒套叠在外筒左半部。操作时,扳手从槽口插入外筒后,将扳手的梅花头或叉子头套在稳定销上,通过伸缩式加力套筒延长力臂,起到了加力作用,加力后的力矩能够达到设备要求,管接头紧固,不易松动,而且本实用新型携带使用方便,省时省力。

Description

伸缩式加力套筒
技术领域
本实用新型涉及一种工程机械维修工具领域的伸缩式加力套筒。
背景技术
国外进口的小型工程机械如滑移式装载机一般都具有体积小、结构紧凑、紧固连接件强度级别高、紧固力矩大的特点,在拆装液压油管接头、操纵阀等零部件时,维修空间小,使用现有普通工具时,维修人员不便把持,零部件紧固后拧紧力矩往往达不到工艺要求。
实用新型内容
本实用新型的目的在于克服现有技术缺陷,提供一种伸缩式加力套筒。
本实用新型的技术方案是这样实现的:伸缩式加力套筒,由外筒和内筒套叠而成,外筒右半部开有凹槽,凹槽中设有稳定销,凹槽右边的外筒端部表面开有槽口,内筒套叠在外筒左半部。
优选的,所述内筒表面沿纵向开有滑槽,螺栓穿过外筒壁伸入内筒滑槽,用于使内筒沿滑槽在外筒内伸缩滑动。
操作时,扳手从槽口插入外筒后,将扳手的梅花头或叉子头套在稳定销上,通过伸缩式加力套筒延长力臂,起到了加力作用,加力后的力矩能够达到设备要求,管接头紧固,不易松动,而且本实用新型携带使用方便,省时省力。
附图说明
图1是本实用新型一个实施例的结构主视图。
图2是图1的俯视图。
图中,1―外筒;2―内筒;3-凹槽;4―稳定销;5―槽口;6-滑槽;7―螺栓。
具体实施方式
下面结合附图作进一步描述。
如图所示,伸缩式加力套筒,由钢管制作的外筒1和内筒2套叠而成,外筒1右半上部开有凹槽3,凹槽3中焊有稳定销4,凹槽3右边的外筒1端部上表面开有槽口5,内筒2套叠在外筒3左半部,内筒2上表面沿纵向开有滑槽6,螺栓7穿过外筒1管壁伸入内筒2的滑槽6,使得内筒2可沿滑槽6在外筒1内伸缩滑动。
操作时,扳手从槽口5插入外筒1后,将扳手的梅花头或叉子头套在稳定销4上,通过伸缩式加力套筒延长力臂,起到了加力作用,加力后的力矩能够达到设备要求,管接头紧固,不易松动,而且本实用新型携带使用方便,省时省力。
