一种在线内孔密封槽测量仪
本技术涉及一种量具,特别是一种在线内孔密封槽测量仪。
技术介绍
目前在航空航天及民用领域的相关部附件中,内孔密封槽的应用非常广泛,特别是在加工航空钛合金等高硬度材料时,机械加工刀具磨损很快,所加工的内孔密封槽尺寸变化较大,所以要测量的频次相对较高,而在制造内孔密封槽时相对简易高效的量具较少,现有的内孔密封槽相关尺寸测量的量具有内径杠杆量表及内卡钳量表,内径杠杆量表只能测量通孔、深度较大的盲孔及槽宽大且浅的内槽,且不能测量槽的宽度及位置度,局限性较大;内卡钳量表只能测量内孔直径和槽宽大且浅的内槽直径,且不能测量槽的宽度及位置度,其受设计原理缺陷,测量误差也相对较大,局限性较大。如中国专利号为200410023993.0的浅盲孔精密量具中,在与所测孔尺寸对应的外径百分尺或标准孔校对好固定测头和杠杆百分表测头的尺寸后,就可对要测的孔的尺寸进行测量,因其测量原理与内径杠杆量表的原理一样,所以测量精度与内径杠杆量表相同,同时也具有内径杠杆量表的缺点,无法测量槽的宽度及位置度,因此仍然需要对此进行改进。
