该内径千分尺特征、 构造及实施方式如下:  The inner diameter micrometer features, construction and implementation are as follows:
该内径千分尺的两个测头分别为固定弯头测头 (13) 和移动弯头测头 ( 14), 当需要测量工件内孔直径时, 测量前, 先将固定弯头测杆(13〉和移 动弯头测头(14)放进校验架 (51 ) 内侧位置 d处, 然后将调节旋钮(7) 向 逆时针方向旋转, 使移动弯头测头(14)接触校验架 (51 ) 内侧位置 d处后 听到棘轮发出达达响声后, 将微分筒(4) 上的微分筒刻度 (47) (见图 11 ) 的 0线刻度值对准支撑套筒(2)上的微分筒刻度值基准线(3), 当 0线刻度 值没有对准微分筒刻度值基准线 (3〉 时, 通过微分筒 (4)上的校准调节孔 (5)进行调节。 调节完毕后再通过微分筒(4)和调节旋钮(7)进行二次校 验, 直至通过调节旋钮(7)里面的弹簧(29)、 棘轮棒(30),和内棘轮(31 ) 自然发出机械传动打滑的达达声音后(其结构见图 3), 微分筒(4)上 0线刻 度值仍然对准微分筒刻度值基准线(3〉才算校验完成,移动弯头测杆刻度(1 ) 的起始测量刻度值(如 25mm)预先设计在尺身(9)的便于测读的可见位置处, 在校验前该起始刻度值的线与尺身至少有 0. 5rara-lmm的距离, 以便该内径千 分尺的两测头放进校验架 (51〉 内, 校验架 (51 ) 的内侧的精密校验尺寸 d 与该内径千分尺的起始测量刻度值相吻合, 以确保校验尺寸的精确。 The two probes of the inner diameter micrometer are a fixed elbow probe (13) and a moving elbow probe (14). When the diameter of the inner hole of the workpiece needs to be measured, the elbow rod is fixed before the measurement (13> And move the elbow probe (14) into the inner position d of the checker (51), then rotate the adjustment knob (7) counterclockwise to bring the moving elbow probe (14) into contact with the check frame (51). After the inner position d is heard and the ratchet is heard, the 0-line scale value of the differential cylinder scale (47) (see Figure 11) on the differential cylinder (4) is aligned with the differential on the support sleeve (2). The cylinder scale value reference line (3), when the 0 line scale value is not aligned with the differential barrel scale value reference line (3>, it is adjusted by the calibration adjustment hole (5) on the differential cylinder (4). The differential cylinder (4) and the adjustment knob (7) are recalibrated until the spring (29), the ratchet rod (30), and the inner ratchet (31) inside the adjustment knob (7) naturally emit mechanical transmission slips. After reaching the sound (the structure is shown in Figure 3), the 0 line scale value on the differential tube (4) is still aligned with the differential tube scale value reference line (3> After the verification is completed, the initial measurement scale value (such as 25mm) of the moving elbow scale (1) is pre-designed at the visible position of the ruler (9) for easy reading, and the initial scale value before verification. The distance between the line and the ruler is at least 0. 5rara-lmm, so that the two probes of the inner diameter micrometer are placed in the check frame (51>, and the precision check size d on the inner side of the check frame (51) Matches the initial measurement scale value of the inner diameter micrometer to ensure accurate calibration dimensions.
当实际测量内径时, 采用微分筒(4) 和调节旋钮 (7 )配合进行, 微分 筒(4)用于快速移动, 即将测头快速移至或移出测量表面, 而调节旋钮(7) 则用于控制操作者的测量旋力, 即当测头己经接触测量表面或';夬要达到最终 测量尺寸数值时就必须使用调节旋钮 (7)来控制操作者的测量力度, 以避免 用力过大而产生的测量误差。  When the inner diameter is actually measured, the differential cylinder (4) and the adjustment knob (7) are used together. The differential cylinder (4) is used for rapid movement, that is, the probe is quickly moved to or removed from the measurement surface, and the adjustment knob (7) is used. To control the operator's measuring torque, that is, when the probe has touched the measuring surface or '; to achieve the final measured size value, the adjustment knob (7) must be used to control the operator's measurement strength to avoid excessive force And the resulting measurement error.
