采用图1所示夹具,在铣床上用锯片铣刀加工大六角螺母的开花槽,可保证质量,提高工效。使用时先把拉紧螺丝头2拧入待铣槽的螺母中,并要与端面大致平齐。然后把拉紧螺丝头2从夹具体两端的圆孔中放入长槽内。工件靠定位销周向定位,由中间靠近定位销的工件开始逐个靠拢锁紧(图1)。为了能多件装夹,夹具体(图2)尽可能取最大允许长度。
Using the fixture shown in Fig. 1, machining a large hexagonal nut blossom slot on a milling machine with a saw blade ensures quality and improves work efficiency. First tighten the screw head 2 into the nut to be milled, and to be flush with the end face. Then tighten the screw head 2 from the folder at both ends of the hole into the long slot. The work piece is positioned circumferentially by the locating pin, and the work piece close to the locating pin in the middle is locked one by one (Figure 1). In order to be able to multi-piece clamping, clamp body (Figure 2) as much as possible to take the maximum allowable length.
