多槽孔零件精度要求较高,给加工和测量带来困难。为了保证零件质量,我们改装了如图所示的内孔槽测量卡尺,能准确无误地反映出精确尺寸,满足了要求。内孔槽测量卡尺由固定板、千分表、卡脚、调节螺钉、弹簧等组成。使用时,松动调节螺钉,调节卡脚位置,用外径百分尺测出D值后,将调节螺钉拧 Multi-slot parts require higher accuracy, to the processing and measurement difficulties. In order to ensure the quality of the parts, we modified the inner groove measuring caliper shown in the figure, can accurately reflect the exact size, to meet the requirements. Internal slot measuring caliper by the fixed plate, dial gauge, card feet, adjusting screws, springs and other components. Use, loose adjustment screw, adjust the card foot position, measured with an outer diameter percentage D value, the adjustment screw
