在有键槽的轴类零件成批加工中,需要检测键槽对轴线的对称度。为了适合工人在生产现场快速检测的需要,我们设计了如图所示键槽对轴线对称度极限量规,量规的基准轴线由V形槽模拟,键槽中心平面对基准轴线的对称度极限误差由量头的工作尺寸φ_1控制,量头的端平面必须与量头的圆柱体垂直,量头与量杆的同轴度公差为0.002mm,量杆与孔的配合间隙<0.002mm,量杆的轴线对称平分V形槽,取角度量块用光隙法检测量杆母线与V形槽两侧斜面的夹角γ,γ应在角度公差带内,并用千
In the key shaft parts of the batch processing, you need to detect the symmetry of the keyway on the axis. In order to meet the needs of workers in the production site for rapid testing, we designed as shown in the keyway axial symmetry limit gauge, gauge reference axis by the V-groove simulation, the central axis of the keyway axis of symmetry limit error by the amount of head Work size φ_1 control, the head end of the plane must be perpendicular to the measuring cylinder, the head and the amount of rod coaxial tolerance of 0.002mm, the amount of rod and hole with the gap <0.002mm, the rod axis symmetry Divide the V-shaped groove evenly and take the angle measuring block to measure the included angle γ and γ of the measuring rod busbar and the slope on both sides of the V-shaped groove with the light gap method within the angle tolerance zone,
