该辅具(苏联发明证书1145237)可高效测量内孔锥度,能直接在加工机床上进行测量。辅具由板2(用于与游标卡尺尺身牢固连按)、三个固定测头3、滑动测头4、拉簧5和直尺1(用于与游标卡尺尺框牢固连接)构成。直尺1与滑动测头接触的斜度段按式a=dtgβC来确定。式中:a—直尺斜面上升值;d—两侧头轴线间的距离;β—读数时线值与角度值之比;C—直尺斜面长度坐标(即直尺移动距离C时上升a——译注)。测头的长度根据被测孔来确定。
The aids (Soviet invention certificate 1145237) can effectively measure the bore taper, can be measured directly on the processing machine. Auxiliary from the board 2 (for the vernier caliper ruler firmly connected), three fixed probe 3, the sliding probe 4, the tension spring 5 and the ruler 1 (for the vernier caliper frame firmly connected) form. Straightedge 1 sliding contact with the sliding section of the slope according to the formula a = dtgβC to determine. Where: a-ruler ramp value; d- distance between the two sides of the head axis; β-reading ratio of the value of the angle and angle; C-ruler length of the bevel (ie ruler move distance C rise a - Annotation). The length of the probe is determined by the hole under test.
