FIELD: machine building. ^ SUBSTANCE: invention refers to machine building, particularly to devices for tool holders of metal-working machines. Device (1) for tool fixture has case (3) with through orifice (31) connected to receiving opening (13) for shank end (15) of the tool. Rotary in axial direction foot bushing (45) of the device with its thrust face (47) adjoins end (23) of shank end (15) of the tool. Foot bushing (45) is screwed into internal thread (43) of through orifice (31) and is connected not rotating, but movable in axial direction, to control tube (49) engaging foot bushing (45). On one side the rotating, but rigid on axis, control tube is mounted on hydraulic clutch (27). At tool cutting lubricating fluid is supplied through hydraulic clutch (27), control tube (49), foot bushing (45) and channels (17). ^ EFFECT: improved passage of lubricant via device for tool holder in system with minimal amount of lubricant. ^ 44 cl, 10 dwg |
