FIELD: machine building.
SUBSTANCE: detachable device has two pivotally connected plates, one of them is intended for rigid installation on the rotating table of the lathe, and another one is installed with inclination relatively to the first one, and is intended for installation on it and securing of machined part in form of wedge, and is connected with the first plate by axle of the pivot with possibility of rotation. Said plates in places opposite relatively to the pivot axle have above each other the stops, each of them is rigidly connected with the appropriate plate. On surface of the bottom stop a cavity is made to install in it the replaceable regulating plate with height exceeding depth of the cavity on surface of the bottom stop.
EFFECT: improved quality of machining and tightness of gate of wedge-gate valves.
