本文所介绍的万能夹具可以用来加工比较精确的偏心、带角度的孔、多头螺纹和需要固定在角铁上的零件。夹具的结构如附图所示。锥形尾柄装在车床的主轴孔内。加工具有偏心或带角度的孔的零件时,可以把零件固定在带有4个T形槽的圆盘2上。圆盘2和3可以沿导向板4移动到我们所需要的位置。移动距离的大小可以通过平板1和档销5控制。 This article describes the universal fixture can be used to process more accurate eccentric, angular holes, multi-head thread and the need to be fixed on the angle iron parts. Fixture structure as shown in the figure. Taper tail handle installed in the spindle hole in the lathe. When machining parts with eccentric or angled holes, the part can be held on a disk 2 with four T-slots. The discs 2 and 3 can be moved along the guide plate 4 to the position we need. The size of the moving distance can be controlled by the plate 1 and the dowel pin 5.
