齿轮节圆夹具是利用弹性自定心鼓膜夹具的结构特点改制而成的,对制齿后的直齿、斜齿圆柱齿轮孔的磨削加工,使用性能可靠,定心定位精度较高。齿轮节圆夹具结构见图1,基盘1和磨床主轴兰盘联结,与夹具体2为一组合件。夹具体2为多爪鼓膜盘,是利用弹簧钢材料制做的,具有一定的涨缩弹力。夹具体鼓膜盘的结构尺寸见图1。应特别注意鼓圆D_1与厚度b的相互适宜。
The gear joint fixture is made from the structural characteristics of elastic self-centering tympanic membrane fixture. The grinding process of spur gear and helical gear hole after the manufacture is reliable and the positioning accuracy is high. Gear pitch circle fixture structure shown in Figure 1, the base plate 1 and grinder spindle flange connection, and the clamp body 2 as a combination. Clamp body 2 is a multi-claw tympanic membrane, is made of spring steel material, with a certain amount of elastic expansion. Clamping the structure of the tympanic disc size shown in Figure 1. Special attention should be drum circle D_1 and thickness b of each other appropriate.
