在中小批螺钉铣槽时,过去,我们一直是用三爪卡盘夹紧工件,由铣床工作台纵向往复一次铣一个工件,不仅效率低,而且工人劳动强度大。现在,我们制造、使用了如图所示快装自紧自卸铣槽夹具,提高了工效,减轻了劳动强度。夹具结构简单,制造容易,通用性强。其结构如图所示。在活动盘7与固定盘8之间装一薄垫圈1,使两盘之间留有0.5毫米的间隙,当轴承外圈推动活动盘的上端时,活动盘形成杠杆
In small and medium-sized screw milling slot, in the past, we have been using a three-jaw chuck clamping workpieces, the milling table reciprocating milling a workpiece longitudinally, not only inefficient, but also labor-intensive. Now, we make and use the quick-loading self-tightening self-draining mills as shown in the picture, which improves work efficiency and reduces labor intensity. Fixture structure is simple, easy to manufacture, versatility. Its structure as shown. A thin washer 1 is arranged between the movable plate 7 and the fixed plate 8 so as to leave a gap of 0.5 mm between the two plates. When the bearing outer ring pushes the upper end of the movable plate, the movable plate forms a lever
