背景技术 Background technique
对于大直径深孔内孔的检测，常规游标卡尺受量爪深度的限制不能直径测量，通常采用的是内径千分尺，但是需通过接杆接长，使用过程中，一方面为避免自重对检测结果的影响，需在内径千分尺全长尺寸两端安装支承，提高了检测难度，生产现场不便操作，另一方面一般内径千分尺不附带测力装置，同时为避免旋转力过大损害千分尺或旋转力过大造成很大的误差这种问题的出现，对测力的大小要求很高；另外，大直径内径千分尺采购成本很高，不利于现场操作使用。 For the detection of large-diameter deep holes, conventional vernier calipers cannot measure the diameter due to the limitation of the depth of the measuring jaws. Usually, an inner diameter micrometer is used, but it needs to be extended by an extension rod. Affected, it is necessary to install supports at both ends of the full length of the inner diameter micrometer, which increases the difficulty of detection and is inconvenient to operate on the production site. The emergence of the problem of causing large errors requires high force measurement; in addition, the purchase cost of large-diameter inner-diameter micrometers is very high, which is not conducive to on-site operation and use.
目前，尚未有一款专用于测量大直径深孔、并行之有效的内径测量装置。 At present, there is not yet an effective internal diameter measuring device specially designed for measuring large diameter deep holes.
