我厂加工某一工件时,采用划线后加工难以保证精度,所以设计了定位块移动式框架钻铰夹具,在摇臂钻床上能一次装夹加工出2—φ8.1_0~(+0.022)mm和9mm三个孔。 如图所示,加工时将工件放在滑块7上,以工件E面定位,然后推入模架体3内,分别由定位块10、12完成两个方向的定位,并用螺钉1预紧。尔后用螺钉8将滑块7固定在模架体3上,以免加工时 I plant processing a workpiece, the use of scribing difficult to ensure the accuracy of the processing, so the design of the positioning block mobile frame drilling hinge fixture, in the radial drilling machine can be a folder processing 2-φ8.1_0 ~ (+0.022) mm and 9mm three holes. As shown in the figure, when processing, the workpiece is placed on the slider 7, positioned on the workpiece E surface, and then pushed into the mold body 3, respectively, by the positioning block 10,12 to complete the two directions of positioning and preload with the screw 1 . Thereafter, the slider 7 is fixed on the mold frame body 3 by a screw 8 so as to avoid processing
