十二、英国机械工业中具有代表性的钻模及夹具(介绍36种) 下面介绍的为目前英国机械工业生产中具有代表性的钻模和夹具,共三十六种,用立体图、剖视图介绍其结构,图文对照。具体叙述如下。夹紧原则(图1) 在设计钻模和夹具时,最重要之点是钻模或夹具的结构必须具有足够的刚性和稳定性,能防止工件产生任何的位移、以及由于加工负荷引起的工件变形和振动。在可能的情况下,切削力应直接作用在一个固定的部位上,而不 Twelve, the representative of the British machinery industry in the drilling and fixture (36 kinds introduced) Here are the current British machinery industry in the production of a representative drill and fixture, a total of 36 species, with a perspective view of the cross-sectional view Its structure, graphic control. Specific description is as follows. Clamping principle (Figure 1) The most important point in designing a drill and a fixture is that the structure of the drill or fixture must be sufficiently rigid and stable to prevent any displacement of the workpiece, as well as the workpiece due to machining load Deformation and vibration. Where possible, the cutting force should act directly on a fixed part, not
