Abstract

本实用新型公开了一种可换式金属切削刀具,它由刀头和刀杆组成,其主要特征是刀杆横向设有一长槽孔,纵向至少设有一个与长槽孔相通的螺纹孔,刀头的后部置于长槽孔内,螺纹孔内设有定位调节螺栓。本实用新型结构简单,使用方便,刀头和刀杆的连接不用焊接工艺,故既节约金属材料,又可保持刀头的硬度。

Description

可换式刀具
本实用新型涉及一种金属切削刀具。
传统的机械金属切削刀具由焊接在一起的刀头和刀杆组成。上述刀具虽结构简单，但有以下缺点：1.在焊接时，若时间过长，或温度过高，会影响刀头的硬度，如焊接时间过短、或温度过低，则会影响焊接牢度，刀头易脱落。2.使用过程中，一旦刀头刃口磨损，必须将整个刀具从机床上拆下，不但装夹心比较麻烦，而且往往因刀头和刀杆固定焊接在一起，只能同时报废，故浪费较大。
本实用新型的目的是提供一种结构简单，安装方便，能省材节时的金属切削刀具。
本实用新型由刀杆和刀头组成，刀杆横向设有一长槽孔，纵向至少有一个与长槽孔相通的螺纹孔，刀头的后部置于长槽孔内，螺纹孔内设有定位调节螺栓以固定刀头。
由于本实用新型的刀头置于刀柄的长槽孔内，并由定位调节螺栓固定，当刀头磨损时，仅需松开定位调节螺栓，就能将刀头拔出，更换或修磨。本实用新型的刀杆可一次装夹，长期使用，无需更换，故既可节约金属材料，又可节省工作时间。对刀头而言因无焊节工艺，刃口的硬度不受影响，而且更换和修磨也十分简便。
附图1为本实用新型结构示意图。
图中1-刀杆、2-刀头、3-定位调节螺栓。
以下结合附图及实施例进一步描述本实用新型。
参见附图1，本实施例的刀杆(1)为45钢锻析，杆身横向开有长度为68mm的长槽孔，孔内装有刀头(2)，刀杆(1)的纵向开有二个与矩形长槽孔相通的螺纹孔，螺纹孔内各设有一定位调节螺栓(3)，拧紧该螺栓便可将刀头(2)紧定，反之，则可将刀夹(2)抽出。本实用新型用途广泛，特别适合于粮食加工机械如磨粉机的磨辊拉丝等。
