用光滑量规测量孔径,既方便,效率又高。当小批量生产时,可自制量规,其方法如下: 结构见附图,在柄体上装同型号的两只轴承,通过螺帽,左右压垫和中间隔套,将轴承外圈固定。柄体两端打有B2.5/6中心孔,将轴承外圈磨至所需尺寸。中间隔套在磨削时起退刀槽作用,若需减轻重量,可将柄体做成空心的。 Measuring aperture with a smooth gauge, convenient, efficient and high. When the small batch production, can be made of gauges, the method is as follows: The structure shown in the drawings, the handle body loaded with the same type of two bearings, through the nut, left and right pressure pad and the spacer sleeve, the bearing outer ring fixed. B2.5 / 6 center hole hit the ends of the handle body, the bearing outer ring mill to the desired size. The spacer sleeve acts as a relief groove when grinding. If the weight needs to be reduced, the handle body can be made hollow.
