【技术实现步骤摘要】
用于实验室手持式钻孔机垂直夹持与导向装置
本技术属于一种钻孔机夹持与导向装置,具体涉及一种实验室手持式钻孔机垂直夹持与导向装置。
技术介绍
目前,在实验室用手持式钻孔机对试件进行垂直钻孔时,钻孔机一般采用手持或装置夹持。但是不论采用手持或用装置夹持都存在很多弊端:一是由于钻孔机的震动,手或夹持装置会随着钻机轻微摆动,这样钻出的钻孔角度随机性较大,达不到实验设计要求,而且钻孔时钻机的摇摆会扩大钻孔口甚至破坏试件,而且当钻杆较细较长时,钻机的摆动会使钻杆变弯甚至折断;二是手持钻孔机钻孔时,钻孔机的重量全靠手的支持,十分消耗体力;三是用现有的夹持装置夹持钻孔机钻孔时,钻孔机在垂直方向上的移动距离会受到限制,当钻孔较深时就无法使用;四是现有的夹持装置没有办法固定试件,当对较小的试件钻孔时,钻杆的转动会带动试件转动,影响钻孔的角度;五是由于现有的夹持装置夹持的钻机不能移动,当在较大的试件不同位置钻孔时,需要不断移动试件,费时费力,同时也造成试件固定困难。
