Description
Technical field
The utility model relates to a kind of locking device, belongs to technical field of metallurgical equipment.
Background technology
During big specification shaped steel product of aligning, because the product cross section modulus is big, it is big to align required axial force, and straightener adopts the form of hydraulic locking or hydraulic pressure+mechanical interlocking that collars is locked more.Yet for the shaped steel product than small dimension, required axial force is little, and straightener adopts the hydraulic locking form collars to be locked cost of investment and the operation cost of meeting increase equipment.
The utility model content
The purpose of this utility model provides a kind of axle head locking device that need not the section straightener of hydraulic mechanism.
To achieve these goals, by the following technical solutions: a kind of axle head locking device of section straightener, it is characterized in that: described locking device comprises first key that is arranged on the axle sleeve, the locking end cap is fastened to collars pad and collars on the axle sleeve, smoothing roll is provided with second key, described locking device also comprises retaining ring and the locking nut that cooperatively interacts, wherein on the double-screw bolt that locking nut is arranged on smoothing roll is connected, locking nut is the external splines shape, the cross section of locking nut is convex, and the locking nut endoporus is processed with the screw thread that cooperates with double-screw bolt, and the inside of locking nut is provided with bolt hole, after the double-screw bolt threaded engagement, by bolt and double-screw bolt locking; Wherein the retaining ring endoporus is the internal spline shape, and the cross section of endoporus is spill, and the circumference of retaining ring is provided with through hole, is provided with the locking screw screw bolt and nut in the through hole.
The utility model is simple in structure, weight of equipment is light, need not hydraulic locking apparatus, from having reduced equipment investment to a great extent, effectively reduces cost of investment and operation cost.
