Description
Technical field
The utility model belongs to component of machine field, particularly relates to a kind of locking nut of high-speed rod-rolling mill tube reducing unit roll installation hydraulic gripping apparatus.
Background technology
High-speed rod-rolling mill tube reducing unit roll need use hydraulic gripping apparatus when installing, and dress roller pressure is generally at about 150bar, and its reaction force all concentrates on hydraulic gripping apparatus locking nut, and therefore whether locking nut locks is the key point ensureing roll installation quality.The maternal employing of locking screw is threaded, and because working space is less, spanner cannot be used to dismantle, can only with the hands be tightened on roll shaft by locking nut, closely cooperate with hydraulic gripping apparatus.Therefore, often occur that locking nut does not tighten the problem occurring loosening, not only need running check and manually fastening, and very easily cause roll that not in place and quality accident that is that produce is installed.
Summary of the invention
The utility model aims to provide one and is convenient to fastening, can ensure that locking nut does not loosen, thus avoids because installing not in place and producing the hydraulic gripping apparatus locking nut of quality accident.
For this reason, the solution that the utility model is taked is:
A kind of hydraulic gripping apparatus locking nut, it is characterized in that, described locking nut be in the middle of one with stage shape circular hole, lower end with the cylinder of trapezoid boss, at least 10 road tip surfaces are equidistantly processed with along cylindrical outer surface axis direction, stage shape circular hole epimere is sleeve hole, and hypomere is connecting hole, and sleeve hole diameters is greater than connecting hole diameter, sleeve hole hole wall is axially equidistantly processed with deep-slotted chip breaker, and connecting hole hole wall is with internal thread.
Described locking nut outer wall top is equidistantly provided with screw hole.
The beneficial effects of the utility model are:
The utility model structure is simple, is convenient to fastening, does not loosen after locking nut screwing, both can shorten the set-up time, can guarantee that again roll is in place, the quality accident avoiding collars to loosen causing.
