在机械制造中,各种形状和角度的弯接头是经常遇到的,除了要在两端车削内螺纹或外螺纹外,还要从不同角度的两端分别打孔准确接通,加上这类接头的毛坯都是外形不规则的锻、铸件,不便于直接装夹和找正,这给机械加工带来麻烦。为此,我们设计了一种很简易的工装,巧妙地解决了这个问题。此工装是一根短圆棒的一个端面上铣斜面,使其夹角等于90°-α,再根据工件尺寸 L,计算出偏心距(e=L.sina),划线后在斜面上钻孔,孔径的大小与工件外径相适应,最后将孔的出口处铣平(见附图),至此,简易夹具就作好了。使用时,将工件已加工好了
In machinery manufacturing, the bending joints of various shapes and angles are often encountered. In addition to turning the internal thread or the external thread at both ends, the two ends of different angles are respectively drilled to be accurately connected, and this The joints of the rough are irregular shape forging, casting, not easy to clip and find the correct, which brings trouble to the machining. To this end, we designed a very simple tooling, cleverly solved the problem. This tool is a short rod on one end of the milling bevel, so that the angle is equal to 90 ° -α, and then according to the size of the workpiece L, calculate the eccentricity (e = L.sina), crossed the slope on the drill Hole, the size of the aperture and the outer diameter of the workpiece to adapt, and finally the mouth of the hole milling flat (see photo), so far, simple fixture to make it. When used, the workpiece has been processed
