带顶针的挖槽刀架装置在组合机床上的应用

摘要

It is difficult to cut a slot on the outer circle, especially wide groove processing. Straight joints and T-fast-inserting joints, as multiple-grooved structure parts with straight flutes or chutes on excircle, should be clamped at once to implement the forming process in different directions. If the traditional cylindrical cutting process is used, it is easy to generate the vibration ripples, and needs more facilities. Nowadays this paper designs a trench knife rest device with a thimble on the modular machine tool. The model is not only used to solve the clamping rigidity of the parts, but also to form a plurality of grooves on the outer circle at one time. In the actual processing, it is verified that the quality of the processed parts is up to standard and its operation is smooth.%在外圆切削中割槽特别是宽槽的加工是一道难题,而直通或三通快插接头为多槽结构的零件,其外圆上有多个直槽或者斜槽,并且需一次装夹完成几个方向的成形加工.如果用传统的外圆切削割槽工艺容易产生振纹,且需要配备较多的设备.现设计了一种在组合机床上采用带顶针的挖槽刀架装置,不但解决了零件的夹持刚性,而且可一次装夹成型切削外圆上的多槽,经实际加工验证所加工的零件质量合格、稳定.
