在使用机床夹具铣制形状简单的工件时,往往是装卸工件的辅助时间多于切削时间,这当然是不经济的。为了减少辅助时间,应在一次装夹中夹几个工件。本文介绍一种多工位铣夹具作为例子。被铣削的工件是燕尾形镶条。一次装夹四件,上下左右四个面在一次行程中同时铣出。夹紧工件用手动拧紧手把,这样更为方便迅速,因为如果使用扳手,很易丢失,且不方便。工件形状或尺寸变更时,可以更换相应的夹具上体。
Of course, it is uneconomical to mill workpieces of simple shapes using a machine tool fixture, often with more auxiliary time for loading and unloading workpieces than cutting time. In order to reduce the auxiliary time, should be in a folder in the folder a few pieces. This article describes a multi-position milling fixture as an example. Milled workpiece is a dovetail trim. A folder of four, up and down about four sides in a trip at the same time milling. Clamping the workpiece manually tighten the handle, so more convenient and quick, because if you use a wrench, it is easy to lose, and inconvenient. When the shape or size of the workpiece is changed, the corresponding fixture upper body can be replaced.
