五、几种常用夹具目前,各厂对滚丝机夹具采用情况差别较大。现就我厂使用的滚丝机夹具作一介绍。 1.可调节挡板(图19) 这种挡板用在工件前端定位的产品上。它制造简单、使用方便、适应性强,当产品更换时,只要换一下挡铁就可继续使用。 2.上支承悬臂夹具(如图20) 这种夹具适用于加工以孔定位的,旋转时离心力大的零件,如弯接嘴、三通接嘴等。这种夹具操作方便,不易产生事故;能控制零件偏摆,保证产品的质量;调整简单,只要注意转动心轴与滚丝轮主轴成水平,并与滚丝轮端而互相垂直就行了。由于该夹具后轴承悬臂较长,装滚丝轮时应注意各个方向的间隙,防止与机床相碰。 3.摆动夹具(如图21)
Fifth, several common fixture At present, the plant on the rolling machine fixture using a large difference. Now I use the rolling mill machine fixture for an introduction. 1. Adjustable Bezel (Figure 19) This bezel is for the product located on the front of the work piece. It is simple to manufacture, easy to use, adaptable, when the product is replaced, just change the block iron can continue to use. 2 on the support cantilever fixture (Figure 20) This fixture is suitable for processing holes to locate the rotation of the centrifugal force of large parts, such as bending mouth, mouth and other three-way nozzle. This fixture is easy to operate, easy to produce accidents; can control the deflection of the parts, to ensure product quality; simple adjustment, as long as the attention to the rotating mandrel level with the rolling wheel spindle, and the rolling wheel ends perpendicular to each other on the line. As the fixture bearing longer cantilever, loaded roller should pay attention to the gap in all directions to prevent collision with the machine. 3. swing fixture (Figure 21)
