以前我们在加工如图1所示的小刀架螺母时,是按划线在四爪卡盘上找正车削的。这种方法的缺点是要有一道划线工序,用于找正的辅助时间较长。T14×3螺纹孔轴线对圆柱母线的垂直要求不易保证,T14×3轴线与φ30ga轴线相交的要求也不易达到。现在采用了如图2所示的夹具。一、结构特点:先将带有V型槽的夹具体5拧到主轴上,然后将工件15放入V型槽中,用压板3压住工件,并拧紧螺母4和12,即可进行加工。调节螺钉1可用来调节螺母对主轴的中心位置。二、优缺点:这种夹具使用方便,不要求技术熟练程度较高的工人橾
In the past we are processing the small knife holder nut as shown in Figure 1, according to the scribe in the four-jaw chuck to find turning. The disadvantage of this method is to have a scribing process, the longer the auxiliary time for finding positive. The vertical requirements of the T14 × 3 threaded hole axis on the cylindrical bus bar are not easily guaranteed, and the requirement of intersecting the T14 × 3 axis and φ30ga axis is not easy to achieve. Now use the fixture shown in Figure 2. First, the structural features: First with the V-groove clamp body 5 onto the spindle, and then the workpiece 15 into the V-groove, with the pressure plate 3 to suppress the workpiece, and tighten the nuts 4 and 12, can be processed . Adjustment screw 1 can be used to adjust the nut’s center position on the spindle. Second, the advantages and disadvantages: This fixture easy to use, does not require skilled workers 橾 higher
