Abstract
The utility model belongs to a metallurgical equipment fastening piece and provides a novel device for locking a nut clockwise and counter-clockwise. The device for locking the nut clockwise and counter-clockwise is especially suitable for using for a straightening machine system. The device for locking the nut clockwise and counter-clockwise at least includes a screw (1) and the nut (3). The device for locking the nut clockwise and counter-clockwise is characterized in that when the screw (1) is threaded with the nut (3), the bottom end of the nut (3) is connected with a press cover (5) fixedly through a lock screw (6). The head part of the press cover (5) is threaded into the screw (1). The device for locking the nut clockwise and counter-clockwise is good in locking effect, easy to process and put into practice. And by using the device for locking the nut clockwise and counter-clockwise, whether the nut becomes flexible or not can be observed easily.
Description
Technical field
The utility model belongs to the metallurgical equipment fastening piece, is specially adapted to a kind of novel positive and negative nut anti-looseness device that the straightening machine system is used.
Background technique
Existing nut anti-looseness technology has had a variety of, but high strength, large load and repeatedly concussion impact locking with large-scale nut of place, remain a critical technical barrier.Existing several locking mode is as adopted large-scale round nut, nut pad, and it processes comparatively difficulty, and its nut pad reliability under high-strength impact load repeatedly is not high; The mode of double nut and internal thread locking screw also easily produces loosening under the effect of larger axial force.
Summary of the invention
The purpose of this utility model is: a kind of novel positive and negative nut anti-looseness device is provided, and its anti-loosing effect is good, and whether loosening easily processing, enforcement easily, easily observe out screw thread.
The technical solution of the utility model is: a kind of novel positive and negative nut anti-looseness device, which comprises at least screw mandrel, nut, it is characterized in that: when screw mandrel, with together with nut is screwed in the time, the bottom of nut is fixedly connected with gland by lock screw, and the gland head is threaded into screw mandrel.
Described screw and the gland spun with screw mandrel is integrative-structure.
Be pressed with the adjustment pad between described nut bottom and gland.
Described screw mandrel end internal thread with external thread rotary to contrary.
The described gland spun with screw mandrel is screwed in the central part of screw mandrel, and the lock screw spun with the nut bottom is screwed on the bottom end of nut symmetrically.
Described its shearing force summation can bear of lock screw spun with nut should be less than the shearing force that gland end screw can bear.
The described lock screw length spun with the nut bottom should be greater than the thickness of gland, and gland can be fastened to nut end face.
The described thickness of adjusting pad by adjustment, make lock screw just screw in the nut end tapped hole.
Described spacer sheet material is the material of capable of adjusting thickness.
The outside thread of axle coordinates with nut, it coordinates for right-handed thread, by the mode that is embedded in screw, nut is tentatively locked, a left handed threaded hole is attacked in the end of axle, tightening cover is screwed in, and aim at the hole on nut screwing sky and tightening cover by the thickness of repeatedly adjusting packing ring, with eye bolt, that tightening cover and nut handle is tight, and with steel wire, bolt is worn.So, if nut has loosening, must drive the tightening cover rotation, tightening cover is left-handed cooperation with shaft part again, its screw-in mode should be revolves tighter and tighter, so so the loosening power of whole nut has become to the shearing force closing nut and tightening cover bolt, if, if nut is deviate from, must need first to cut off the bolt of outer ring, perhaps cut off on tightening cover the screw of self, once such phenomenon occurs, and we have just known nut loosening, needed again locking nut.
Characteristics of the present utility model are: this New anti-loose fastening piece it to have an anti-loosing effect good, thoroughly stopped the loosening of screw thread structure.And its enforcement is comparatively easy, component are more easily processing also.And whether be easier to observe out screw thread loosening, after thread looseness, will inevitably at first cut off row's screw of outer ring.Thereby it utilizes the different principle of thread rotary orientation difference action direction, thoroughly suppressed the trend of thread looseness.It can be used in conjunction with together with other locking modes, such as housing screw, has further strengthened anti-loosing effect.
Effect of the present utility model: while taking full advantage of screw thread rotation, thereby due to the different principle of different its moving direction of thread rotary orientation, suppressed up hill and dale the loosening of screw thread structure, especially the application in screw-down on straightening machine, thoroughly prevent the loosening of the screw thread that causes due to jerk repeatedly, reached good using effect.
The accompanying drawing explanation:
Below in conjunction with embodiment's accompanying drawing, the utility model is described in further detail:
Fig. 1 is the example structure schematic diagram.
In figure: 1, screw mandrel; 2, adjustment ring; 3, nut; 4, adjust pad; 5, gland; 6, lock screw.
Embodiment
Embodiment 1: a kind of novel positive and negative nut anti-looseness device, it comprises that it comprises screw mandrel 1, nut 3, gland 5, lock screw 6, adjusts pad 4, it is characterized in that: when nut 3 is wanted loosening the disengagement due to the long-term vibration impact, screw mandrel 1 is motionless, nut 3 rotation, nut 3 end faces and gland 5 are rigidly connected by lock screw 6, and gland 5 heads are because the another kind of rotation direction of employing is threaded into screw mandrel 1, two kinds of screw thread movement tendency differences, thus the loosening of nut 3 thoroughly suppressed.The utility model is applied in the straightening machine system, thereby has avoided the loosening of the screw thread that causes due to prolonged and repeated jerk.
Embodiment 2: substantially the same manner as Example 1, difference is that nut 3 itself adopts the internal locking screw, thereby has further suppressed the loosening of screw thread.
