薄壁零件的加工一直是感到头痛的问题。一般使用的夹具有机械夹紧式和液性塑料夹固式两种,但它们都有不足之处。为此,我们在参阅有关资料的基础上,自行设计制造了一种用钢球作填料的弹性胀紧式磨夹具。实践证明,该夹具有结构新颖,使用方便,夹紧可靠,定心精度高等优点。 弹性胀紧式磨夹具主要由夹具体1、弹性套2、钢球3和方头螺钉4等组成,见附图。使用前,先将弹性套装入夹具体内,然后填入钢球,旋上螺钉,装进工件 The machining of thin-walled parts has always been a headache problem. General use of the folder with a mechanical clamping and liquid plastic clamp two, but they have shortcomings. To this end, we refer to the information on the basis of their own design and manufacture of a steel balls for the expansion of the elastic expansion Clamps. Practice has proved that the clip has a novel structure, easy to use, reliable clamping, high centering accuracy. Elastic bulging mill fixture mainly by the clamp body 1, elastic sleeve 2, ball 3 and the square head screws 4 and other components, see the accompanying drawings. Before use, put the elastic sleeve into the clamp body, then fill the ball, screw on the screw
