平口钳在铣、刨、钻等机加工中应用极广。特别在钳口夹紧、松开频繁的场合,手工操作劳动强度很高。为了减轻劳动强度,提高工作效率,我们革新改制了一台电动平口钳。经过半年来生产实践的考验,效果很好。这种电动平口钳制造简单、使用方便、夹紧力可调、安全可靠、维修容易、工效提高2～3倍,很受操作工人的欢迎。电动平口钳由机械和电气两部分组成。结构如图所示。由550瓦的微型电动机6带动单头蜗杆,经40齿的蜗轮减速,运动传到丝杠,丝杠在原来的螺母中旋转,从而带动活动钳口作张开或闭合运动。整个改装部分的零件只有5只。原平口钳不作任何改动。蜗轮变速箱采用二硫化钼润滑,故不存漏
Flat-nose pliers in the milling, planing, drilling and other machining applications is very wide. Especially in the jaw clamping, release frequent occasions, manual operation of high labor intensity. In order to reduce labor intensity, improve work efficiency, we innovatively transformed a electric jaw. After six months of production practice test, the effect is very good. This electric flat nose pliers manufacture is simple, easy to use, adjustable clamping force, safe, reliable, easy maintenance, work efficiency increased by 2 to 3 times, very popular with the operators. Electric jaw pliers by the mechanical and electrical two parts. Structure as shown. Driven by a 550-watt micro-motor 6, a single-headed worm gear is decelerated by a 40-tooth worm gear and transmitted to a lead screw. The lead screw rotates in the original nut, thereby driving the movable jaw to open or close. The entire modified part of the parts only 5. The original level pliers without any changes. Worm gearbox with molybdenum disulfide lubrication, it does not leak
