在机械加工中,往往需要不同高度的垫铁来配合工装夹具使用。最常用的方法是用不同厚度(如δ=1、2、3……)的铁板切成长方形条板,供不同高度值叠厚的需要,但在使用过程中有如下不足之处: (1)每道机加工工序中,需配备相当数量的垫片使用,保管很不方便。 (2)薄垫片被叠的两面高低不平许多片叠起来后片与片有缝隙,易造成被支撑或夹紧在机床上的刀具或 In machining, often require different height horn to work with fixtures. The most common method is to use different thickness (such as δ = 1, 2, 3, ...) cut into rectangular strip of iron for different height value of the need for stack, but in the course of the following deficiencies: 1) Each machine machining process, the need to be equipped with a considerable number of gaskets, storage is not convenient. (2) thin shims stacked on both sides of the uneven Many sheets stacked after the film and the gap, can easily be supported or clamped on the machine tool or
