Abstract
The invention belongs to metallurgical equipment fasteners, and particularly relates to a novel locking fastener applicable to a straightener system. The novel locking fastener at least comprises a screw rod (1) and a nut (3), and is characterized in that when the screw rod (1) and the nut (3) are screwed together, the bottom end of the nut (3) is fixedly connected with a pressure cover (5) through a locking screw (6), and the head of the pressure cover (5) is screwed in the screw rod (1) in a threaded way. The novel locking fastener has the advantages of being good in locking effect and easy to process and implement, and ensuring that a user can easily observe whether the thread is loosened.
Description
Technical field
The invention belongs to the metallurgical equipment fastening piece, be specially adapted to a kind of novel fastener that the straightening machine system uses.
Background technique
Existing nut anti-looseness technology has had a variety of, but high tenacity, big load and repeatedly concussion impact place locking with large-scale nut, remain a critical technical barrier.Existing several kinds of locking modes are as adopting 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 lock screw also is easy to generate loosening under the effect of bigger axial force.
Summary of the invention
The objective of the invention is: a kind of novel fastener is provided, and its anti-loosing effect is good, is prone to processing, implements easily, and whether the easy screw thread of observing out becomes flexible.
Technological scheme of the present invention is: a kind of novel fastener, which comprises at least screw mandrel, nut, and it is characterized in that: when screw mandrel and nut are screwed in a time-out, the bottom of nut is fixedly connected with gland through lock screw, and the gland head is threaded into screw mandrel.
Described screw and the gland that spins with screw mandrel is integrative-structure.
Be pressed with the adjustment pad between described nut bottom and the gland.
Described screw mandrel end internal thread and external thread rotary are on the contrary.
The described gland that spins with screw mandrel is screwed in the central part of screw mandrel, and the lock screw that spins with the nut bottom is screwed on the bottom end of nut symmetrically.
The shearing force that its shearing force summation that can bear of lock screw that described and nut spin should can bear less than gland end screw.
The lock screw length that described and nut bottom spin should be greater than the thickness of gland, and can gland be fastened to nut end face.
Described thickness through adjustment adjustment pad makes lock screw screw in the nut end tapped hole just.
Described spacer sheet material is to adjust thickness of material.
The outside thread of axle cooperates with nut, and it cooperates for right-handed thread, with 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 the tightening cover through the thickness of adjusting packing ring repeatedly; With eye bolt with tightening cover and nut tight, and bolt is worn with steel wire.So, loosening if nut has, must drive the tightening cover rotation; Tightening cover is left-handed cooperation with shaft part again, and its screw-in mode should be revolves tighter and tighter, so so the loosening power of whole nut has become a shearing force of closing nut and tightening cover bolt; If, must cut off the bolt of outer ring earlier, perhaps cut off on the tightening cover screw of self if nut is deviate from; In case such phenomenon takes place, and we have just known nut loosening, needed again locking nut.
Characteristics of the present invention are: this novel fastener it to have an anti-loosing effect good, on structure, thoroughly stopped the loosening of screw thread.And its enforcement is more or less freely, and component also are prone to processing.Whether and it is loosening to be easier to observe out screw thread, behind 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, has thoroughly suppressed the trend of thread looseness.It can be used with other locking modes, such as housing screw, has further strengthened anti-loosing effect.
Effect of the present invention: when making full use of screw thread rotation; Thereby because the different principle of different its moving direction of thread rotary orientation; On structure, suppressed the loosening of screw thread up hill and dale; Especially the application in the screw-down on straightening machine has thoroughly prevented because becoming flexible of the screw thread that jerk repeatedly causes reaches good using effect.
Description of drawings
Below in conjunction with embodiment's accompanying drawing the present invention is described further.
Fig. 1 is the example structure schematic representation.
Among the figure: 1, screw mandrel; 2, adjustment ring; 3, nut; 4, adjustment backing plate; 5, gland; 6, lock screw.
Embodiment
Embodiment 1: a kind of novel fastener, and it comprises that it comprises screw mandrel 1, nut 3, gland 5, lock screw 6, adjustment pad 4, is characterized in that: when nut 3 is wanted loosening the disengagement owing to the long-term vibration impact; Screw mandrel 1 is motionless; Nut 3 rotation, nut 3 end faces and gland 5 are rigidly connected through lock screw 6, gland 5 heads since the another kind of rotation direction of employing be threaded into screw mandrel 1; Two kinds of screw thread movement tendencies are different, thereby thoroughly suppressed the loosening of nut 4.The present invention is applied in the straightening machine system, thereby has avoided because the screw thread that prolonged and repeated jerk causes loosening.
Embodiment 2: basic identical with embodiment 1, different is lock screw in nut 3 adopts itself, thereby has further suppressed the loosening of screw thread.
