| description | The utility model provides a top device of horizontal gerar grinding headstock, the headstock is top include before top and back centre, the preceding top switching -over valve that is equipped with,switching -over valve meso position are Y type structure, respectively install a one -way throttle valve in the two chamber return circuits of preceding top hydro -cylinder. The utility model providesa top device of horizontal gerar grinding headstock has changed around the prior art movable sleeve the alive wearing and tearing that top powerful top leads to after tight, produces toply with holding the shakiness, causes the overproof problem of part generating line. The utility model provides a top device of horizontal gerar grinding headstock adopts the switching -over valve of the Y type area choke valve of integrated form, through together integrated with the bicavitary choke valve of hydro -cylinder, has reduced hydraulic circuit's interference, and it is accurate reliable to make itcontrol.
