气动液压夹具是以压缩空气作为动力,油液作为传递动力的介质,通过气动液压增力器,将低压的空气转化为高压油进入夹具的工作油缸,将工件夹紧。气动液压夹具共分两大部分:一是动力部件,即增力器;二是工作部件,即工作油缸及管路等。气动液压夹具的定位夹紧元件和一般机械夹具相同。一、气动液压增力器 (1) 气动液压增力器的工作原理:通过增力器使低压的压缩空气(5公斤/厘米~2)转化为高压的油(80～100公斤/厘米~2),然后进入工作油缸,夹紧工件。增力器是利用巴斯噶原理来增加压力的,即在密封的容腔中充满了
Pneumatic hydraulic fixture is compressed air as a power, the oil as the power transmission medium, through the pneumatic hydraulic booster, the low pressure air into high pressure oil into the work of the clamping cylinder, the workpiece clamping. Pneumatic hydraulic fixtures are divided into two parts: First, the dynamic components, namely booster; Second, the working parts, that is, working cylinders and piping. Pneumatic hydraulic clamp positioning clamping components and general mechanical fixture the same. First, the pneumatic hydraulic booster (1) Pneumatic hydraulic booster works: Through the booster so that low pressure compressed air (5 kg / cm ~ 2) into high pressure oil (80 ~ 100 kg / cm ~ 2 ), And then into the working cylinder, clamping the workpiece. Booster is the use of the principle of Bath Karma to increase the pressure, that is filled in the sealed chamber
