【技术实现步骤摘要】
本技术属于夹具的
,尤其涉及一种液压式复联紧固机构。
技术介绍
摆动夹具普遍应用于制造作业中,通过夹持端的摆动来装载和卸载工件。在现有的夹具组件中,工件通过其自身物理形状与夹持端对应形状之间的匹配而被固定在位,而在实际的作业中,工件的种类繁多,工件的大小形状也会发生变化,如不采用与之相匹配的夹具组件,工件可能会相对于夹持端发生移位,导致工件的最终位置不准确,因而无法将工件正确地安装到合适位置。
技术实现思路
本技术要解决的技术问题是提供一种摆动压紧装置,可较好地夹持工件,防止其移位。为了解决上述技术问题,本技术提供如下技术方案:一种液压式复联紧固机构,包括夹具本体、缸体、作为施力装置的活塞、连杆和夹爪,所述夹爪铰接在夹具本体上,夹爪的从动端用于夹紧工件,夹爪的主动端与连杆铰接,连杆与活塞通过转轴铰接,活塞置于缸体内,活塞通过液压装置驱动。与现有技术相比,本技术的优点在于:需要夹紧工件时,通过液压将活塞向下推动,位于活塞下方的连杆在活塞的带动下顺时针旋转,位于连杆下方的夹爪在连杆的带动下顺时针旋转,从而夹紧工件,可较好地夹持工件,防止其移位;需要松开工件时,通过液压将活塞向上推动,位于活塞下方的连杆在活塞的带动下逆时针旋转,位于连杆下方的夹爪在连杆的带动下逆时针旋转,从而松开工件。进一步,所述夹爪上设有限位块,可与连杆相抵,从而控制夹爪的摆动范围,提高夹爪的利用率。以下结合附图和实施例对本技术技术方案进一步说明:附图说明图1是本技术液压式复联紧固机构一种实施例的结构示意图。具体实施方式如图1所示,本技术一种液压式复联紧固机构,包括夹具本体、缸体4、作为施力装 ...
