随着成组技术(GT)的推广,成组夹具的重要性日益增加,现介绍几种国外的车床用成组夹具,供参考.(一)图1所示的车床成组夹具可以代替坐标镗床,用来加工钻模板、镗模板、偏心盘等具有精密孔系的零件。在该夹具上加工的零件,必须具有外圆表面,以便能用三爪卡盘夹紧。夹具由导向板1、5,花盘9、滑块4、过渡盘10及三爪卡盘11等组成。花盘上装有螺丝2和螺母座3,可使滑块沿导向板移动。导向板上装有标尺7,滑块上装有精确到0.02mm 的游标尺6。导向板5刚性固定,而导向板1则可以在移动滑块后用螺栓12锁
With the promotion of group technology (GT), the increasing importance of group fixture, now introduced several foreign group lathe lathe fixture for reference. (A) shown in Figure 1 lathe group fixture can be used instead of coordinates Boring machine, used to process drilling template, boring template, eccentric disk and other parts with precision holes. Parts machined on this fixture must have a cylindrical outer surface so that they can be clamped with a 3-jaw chuck. Jig by the guide plate 1,5, faceplate 9, the slider 4, the transition plate 10 and the three jaw chuck 11 and other components. The face plate is fitted with screws 2 and nut holder 3 to move the slider along the guide plate. The guide plate is equipped with a ruler 7 with a slide gauge 6, which is accurate to 0.02 mm. The guide plate 5 is rigidly fixed, while the guide plate 1 can be locked with the bolt 12 after moving the slider
