Abstract
The utility model belongs to mechanical coupling technical field, especially relates to a kind of to top formula expanding cover locking nut, and it is characterized in that forming primarily of opening slot nut and the conehead nut be arranged in this opening slot nut, opening slot nut and conehead nut are interference fit.Of the present utility model the advantage that double nut is locking and self-locking nut is locking is merged to top formula expanding cover locking nut, strong ensure that vibration is large, the stability of load large part Bolt Connection, the structural type that it is non-maintaining, Security is high, decrease the line service amount of post personnel, also for the stable operation of equipment provides guarantee.
Description
Technical field
The utility model belongs to mechanical coupling technical field, especially relates to a kind of to top formula expanding cover locking nut.
Background technique
The more bolt and nut of current employing connects anti-loose method has compression spring locking, double nut is locking, self-locking nut is locking, elastic ring nut anti-looseness, slotted nut and locked spacer locking, round nut and locked spacer locking, series connection steel wire is locking, trimming method is locking, bond locking etc., but effect is not very desirable in actual use, especially at vibrating motor, vibrating sieve, the bolt and nut of the equipment key parts such as vibrating material feeding device connects in locking problem, large owing to vibrating, load is large, the bolt and nut of vibrating motor footing usually can be caused to connect loosen, the bolt and nut at vibrating sieve key structure position connects the bolt and nut connection loosened with vibrating material feeding device eccentric motor footing and loosens.In daily production, needing regularly to connect bolt and nut to carry out fastening replacing, then can cause serious equipment accident not in time as safeguarded.
Summary of the invention
It is strong that the purpose of this utility model is to provide a kind of tightness, non-maintaining to top formula expanding cover locking nut, can solve due to vibrate large, load is large and loosening problem that equipment key part bolt and nut is connected.
The purpose of this utility model is realized by following technical proposals:
Of the present utility model to top formula expanding cover locking nut, it is characterized in that forming primarily of opening slot nut and the conehead nut be arranged in this opening slot nut, described opening slot nut and described conehead nut are interference fit.
Described opening slot nut top is provided with the endoporus that groove angle is α, and this bore depth is 1/3 of described opening slot nut thickness.
Described conehead nut bottom is provided with the cone that cone angle is β, and this cone length and described bore depth match.
Described groove angle α is 25
0-32
0.
Described cone angle beta is 25
0-32
0.
Advantage of the present utility model:
Of the present utility model the advantage that double nut is locking and self-locking nut is locking is merged to top formula expanding cover locking nut, strong ensure that vibration is large, the stability of load large part Bolt Connection, the structural type that it is non-maintaining, Security is high, decrease the line service amount of post personnel, also for the stable operation of equipment provides guarantee.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model opening slot nut.
Fig. 3 is the structural representation of the utility model conehead nut.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, of the present utility model to top formula expanding cover locking nut, it is characterized in that forming primarily of opening slot nut 1 and the conehead nut 2 be arranged in this opening slot nut, described opening slot nut 1 and described conehead nut 2 are interference fit.
As shown in Figure 2, it is 25 that described opening slot nut 1 top is provided with groove angle α
0-32
0endoporus 1-1, this endoporus 1-1 degree of depth be 1/3, endoporus 1-1 hole wall of described opening slot nut 1 thickness surface finishment remove materials processing reach 3.2, to ensure required precision when coordinating with conehead nut 2.
As shown in Figure 3, it is 25 that described conehead nut 2 bottom is provided with cone angle beta
0-32
0cone 2-1, this cone 2-1 length and the described endoporus 1-1 degree of depth match, the cone angle of cone 2-1 is slightly larger than the groove angle of opening slot nut 1, reserve swelling amount, on its cone 2-1, according to requirements can process the elastic opening 2-2 of certain interval in the axial direction, conehead end is processed with chamfering, is convenient to install; The surface finishment of cone 2-1 body wall requires that removing materials processing reaches 3.2, to ensure required precision when coordinating with opening slot nut 1 equally.
During installation, first bolt shank 3 is fixed to equipment position of mounting hole, then is fastened on bolt shank 3 by opening slot nut 1, opening direction is as shown in Figure 1, firm closing by opening slot nut 1, secondly conehead nut 2 is fastened on bolt shank 3, be positioned at above opening slot nut 1, conehead direction as shown in Figure 1, along with screwing continuing to increase of dynamics, the conehead part of conehead nut 2 is constantly pressed in opening slot nut 1, elastic opening 2-2 gap in conehead nut 2 conehead part will constantly reduce, simultaneously conehead nut 2 shown in Fig. 1 comparatively opening slot nut 1 magnitude of interference constantly increase, to be tightened to fixed position time, the cone head part of conehead nut 2 divides formation one perpendicular to the outside power of axial direction, by this power, opening slot nut 1 is firmly fixed, corresponding opening slot nut 1 pair of conehead nut 2 applies the inside power in a vertical axis direction, conehead nut 2 is firmly fixed, opening slot nut 1 and conehead nut 2 power in the axial direction restrict again mutually simultaneously, opening slot nut 1 and conehead nut 2 is made to form stable firmly self-locking form, thus reach the fastening object loosened of bolt 3.
Of the present utility model the advantage that double nut is locking and self-locking nut is locking is merged to top formula expanding cover locking nut, strong ensure that vibration is large, the stability of load large part Bolt Connection, the structural type that it is non-maintaining, Security is high, decrease the line service amount of post personnel, also for the stable operation of equipment provides guarantee.
