introduction：jiya hangmo Extrusion honing extrude hone A viscoelastic matrix medium carrying abrasives is used（Grinding medium）A special process in which the surface is repeatedly rubbed under a certain pressure to achieve polishing or removing burrs，Also known as abrasive flow processing。This machining method was originally mainly used to remove burrs in hidden parts or in cross holes，Later, it is applied to the surface of polishing molds or parts，It is also used to polish the surface of EDM or remove the surface deterioration layer,Extrusion honing for edge rounding of mechanical parts has high processing efficiency、Capable of automatic operation、Polishing effect is good, etc

introduction： 1. Ball-and-fork universal joint According to the different shape of the steel ball raceway, the ball-fork universal joint can be divided into two forms: circular groove and straight groove。 Spherical fork universal joint with circular groove raceway type(figure4—6a)Consists of two universal-joint forks、It consists of four transmission steel balls and one centering steel ball。The center line of the circular groove on the two ball forks isO1andO2Circles with equal radii for their centers，O1andO2To the center of the universal jointOequidistant。When the universal-joint two axes are centered around the center of the ballOWhen turning at any Angle，The center of the ball is always at the intersection of the two circles in the center of the raceway，Thus, the output shaft and the input shaft rotate at the same speed。This ball fork
