【技术实现步骤摘要】
一种能夹持较大工件的大力钳
本技术涉及大力钳,具体地说是一种能夹持较大工件的大力钳。
技术介绍
现有手虎钳是由定夹臂、动夹臂及螺栓调节压紧机构组成,使用时,定、动夹臂夹持物体,旋转螺栓夹紧工件,反向旋转松开工件。开口量较小,不能夹持大件物体,而且夹持力小,旋转螺栓比较费力。存在一定缺陷,使用范围受限制。
技术实现思路
本技术的目的在于提供一种能夹持较大工件的大力钳,结构简单,设计合理,制造成本低,使用方便,夹持工件接触面大,使工件夹得更牢固,除了具有传统手虎钳的性能外,还有快速锁紧工件的性能。为了达成上述目的,本技术采用了如下技术方案,一种能夹持较大工件的大力钳,包括固定钳口、活动钳口、固定手柄、活动手柄、掀片、支板,所述固定钳口焊接在固定手柄上端,活动钳口铰接固定手柄,所述活动手柄前端铰接于活动钳口,所述掀片中部铰接于活动手柄中部,所述支板前端铰接于活动手柄,支板后端在固定手柄中部伸入固定手柄内部,所述固定手柄的后端设有调节螺丝,调节螺丝伸入固定手柄内部抵接在支板下端,所述固定钳口、活动钳口均在自己的夹持面设置有铅唇,所述铅唇的宽度为自身厚度的6倍或6倍以上。所述铅唇的内侧面上均设置有均匀分布的V型槽。所述固定手柄的中部与活动钳口之间设有拉簧。相较于现有技术,本技术具有以下有益效果:本技术的固定钳口与活动钳口较宽,钳唇平面上均匀分布着V型槽,夹持工件接触面大,使工件夹得更牢固,除了具有传统手虎钳的性能外,还有快速锁紧工件的性能。附图说明图1为本技术一种能夹持较大工件的大力钳的结构示意图;图2为钳口示意图;图3为图2俯视图。图中:1、固定钳口,2、活动钳口,3、铆 ...
