Abstract
The utility model relates to the field of mechanical parts, and particularly relates to a hydraulic nut. The hydraulic nut comprises a nut body, an oil transporting pipe, an oil chamber, a compacting ring, a countersink, an oil filling hole, and an oil discharging hole, the oil filling hole and the oil discharging hole are disposed in the countersink, the oil filling hole and the oil discharging hole are connected with the oil chamber via the oil transporting pipe, and the clamping ring is embedded in the oil chamber. An ''O''-shaped sealing ring is sleeved at the clamping ring. A joint is disposed on the oil filling hole. The oil discharging hole is provided with an oil discharging valve. The hydraulic nut is advantageous in that, the nut is provided with a hydraulic device, and the hydraulic device can be used to apply pressure upon a workpiece, occupying space is small, dismounting is easy, and pretightening force can be controlled.
Description
Technical field
The utility model relates to the mechanical parts field, especially a kind of hydraulic nut.
Background technique
Some occasion in industries such as machinery, metallurgy, oil, chemical industry is often wanted the pretension of frequent dismounting, fastening bolts and nuts, the pretension of high strength nut particularly, normally adopt torque spanner, hydraulic spanner to wait to realize, owing to will use pre-clamping tool, so the dismounting nut will take certain spatial position, dismounting is very inconvenient, and pretightening force is difficult to control.
The model utility content
In order to overcome existing nut dismounting inconvenience, the unmanageable deficiency of pretightening force, the utility model provides a kind of hydraulic nut.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of hydraulic nut, comprise nut body, transport pipe, oil pocket, hold-down ring, counterbore, tank filler sleeve and drain oil, tank filler sleeve and drain oil are positioned at counterbore, tank filler sleeve is connected with oil pocket by transport pipe with drain oil, and hold-down ring is embedded in the oil pocket.
Be with " O " shape seal ring on the hold-down ring.
Tank filler sleeve is provided with joint.
Drain oil is provided with fuel outlet valve.
The beneficial effects of the utility model are, the structure of hydraulic pressure installation is set on nut, can exert pressure to workpiece by means of hydraulic pressure installation, and it is little to take up room, easy accessibility, and pretightening force can be controlled.
