(1) the flange of the mandrel and sliding sleeve with the gap between the gap must be controlled between the H7 / H6, and to ensure that the flange rotation flexibility. Such as the gap between the mandrel and the slip sleeve is too small, there will be difficult to turn the flange; if the gap is too large, the mandrel radial runout error, affecting the accuracy of workpiece processing requirements.
(2) vertical plate ball positioning hole with the ball with the gap size of the gap must be controlled within 0.05-0.1MM within the ball and spring to ensure flexibility and flexibility.
(3) The fixture is designed according to the rotary fixture design and is positioned by the elastic element. Therefore, it is necessary to control the center hole distance and the depth dimension of the six uniform holes on the flange to reduce the manufacturing positioning error. Otherwise caused by poor contact gap is too large, affecting the positioning accuracy.
