Description

A kind of bolt arrangement and handling method thereof
Technical field
The present invention relates to a kind of bolt arrangement, particularly relate to a kind of bolt arrangement of two fastened component for convenience detach, and use this bolt arrangement to carry out loading and unloading the method for component.
Background technique
Common clamping bolt rotates under force to be needed in two fastening component, thus plays fastening effect.During dismounting, unclamp clamping bolt, component I separated from component II, this for the component conveniently picked and placeed than being easier to operation, but to be unfavorable for that the component picked and placeed operate just more difficult for larger or structure itself.
For the clamping bolt of motor for washer, general clamping bolt rotates in motor for washer axle under active force, thus the rotor of washing machine is connected with stator tightens up.When dismounting, clamping bolt of first dismantling, then takes out rotor, and because of the weight of rotor own, and motor stator and rotor itself coordinate, and takes out rotor and to operate inconvenience, be unfavorable for dismounting.
Summary of the invention
The present invention is based on the defect of above-mentioned prior art, in order to solve the problem, a kind of new fastening bolt structure of special proposition, and use this bolt to carry out loading and unloading the method for component.
The object of the invention is to, by improving the structure of bolt, realizing the component that convenient assembling and disassembling two is fastened, saving time, reduce costs.
In order to realize the object of the invention, the present invention adopts following technological scheme:
A kind of bolt arrangement, comprises bolt head, bolt column, and the epimere of bolt column is provided with the flank being inclined upwardly and extending, and the upper end face radial dimension of flank is greater than the diameter of bolt column.
The inclination angle scope of described bolt flank is 110 ± 5 degree.
Described bolt flank is at least two symmetrically arranged sheet structures, and further, the thickness of sheet structure is 2 ± 1mm, and width range is 10 ± 2mm, is highly 7.5 ± 1mm.
Described bolt head lower end is also provided with integrated ring spacer.
A kind of bolt loading and unloading method, comprise on the bolt with flank, the fastener with binding groove, with under the fastener of mounting hole, there is the acting surface suitable with bolt flank binding groove upper end wherein on fastener, when disassembled, first unscrew bolt, bolt flank is stuck on the acting surface on the fastener suitable with it; Then, continue to rotate, bolt to drive on fastener outward movment together by flank; Finally, bolt screws out completely, complete on fastener with the dismounting under fastener.
When seated, first by bolt under screw thread and flank leading role, be inserted in the binding groove on fastener; Then, will the fastener being inserted with bolt be placed under fastener, the mounting hole under fastener aimed at by bolt; Finally, screwing bolts, complete on fastener with the installation under fastener;
Mounting hole under described fastener is interior threaded hole, and bolt is tightened in interior threaded hole, and what complete with under fastener on fastener is fastening.
Or the mounting hole under described fastener is through hole, adds nut after bolt screws at end, what complete with under fastener on fastener is fastening.
By adopting above-mentioned technological scheme, when the outward turning of bolt own, by flank to be supplied on fastener one be parallel to bolt axis to power upwards, thus can take out of on fastener, the component that so just dismounting two is secured together easily, save time, reduce costs.
Accompanying drawing explanation
Fig. 1 is bolt stereogram of the present invention;
Fig. 2 is the bolt plan view described in invention;
The embodiment of Fig. 3 bolton component of the present invention assembles schematic diagram;
Fig. 4 is the partial enlarged drawing in Fig. 3.
Number in the figure: 1. bolt head, 2. bolt column, 3. flank, 4. air ring, 5. rotor, 51. binding grooves, 52. acting surfaces, 6. stator, 61. mounting holes, 7. motor shaft
Embodiment
Below in conjunction with accompanying drawing, the method for bolt arrangement provided by the invention and these bolt arrangement tightening and loosening component of use is described in detail.
Fig. 1, Fig. 2 illustrate the concrete structure of bolt of the present invention, comprise bolt head 1, bolt column 2, the epimere of bolt column is provided with the flank 3 being inclined upwardly and extending, the bottom end of flank comes from bolt column, the upper end face radial dimension of flank is greater than the diameter of bolt column, and said radial dimension namely refers to the overall greatest width dimension of two flanks herein.The inclination angle of the upper-end surface bolt flank of flank is 109 degree, and up big and down small flank shape ensure that progressive guiding during installation, and when ensureing again dismounting, the upper-end surface of flank can snap on the inner face of fastened part.In the present embodiment, bolt flank is two symmetrically arranged sheet structures, and the thickness of sheet structure is 2mm, and width is 10mm, be highly 7.5mm, flank should have certain elasticity, is convenient to install, there is certain rigidity again, can take out of on fastener when guaranteeing dismounting.In order to increase fastening strength, being also provided with integrated ring spacer in bolt head lower end, increasing the area of contact of bolt and part.
Fig. 3 needs the component of tightening and loosening for the rotor of motor and stator as two, illustrate fastening after assembling condition.Comprise bolt, rotor 5, the stator 6 with flank, motor shaft 7, there is the acting surface 52 suitable with bolt flank binding groove 51 upper end of its rotor 5, and motor shaft upper end is provided with interior threaded hole 61.Using the bolt method of the present invention's rotor for convenience detach, is realize by increasing by two flanks with inclination angle on clamping bolt.
Before washing machine is installed to stator, first by bolt under screw thread and flank leading role, be inserted in the binding groove of rotor; Then, be placed on stator by the rotor being inserted with bolt, the mounting hole of motor shaft aimed at by bolt, and swivel bolt is fastened on motor shaft, completes the installation of rotor and stator.
When dismantling washing machine motor rotor, first unscrew bolt, upper-end surface acting surface contact in rotor of bolt flank, in force transmission to rotor inner face give rotor one be parallel to bolt axis to power, rotor rises under power effect, and namely bolt is by flank rotor driven outward movment together; Finally, bolt screws out completely, and washing machine motor rotor is easy to separate with stator, completes the dismounting of rotor and stator.
In the present embodiment, the inside of motor shaft mounting hole is threaded, and after bolton puts in place, stator and rotor are fixed together.Other technological scheme (illustrating), when mounting hole is through hole, bolt is by after on fastener, under fastener, and end adds nut, and what complete with under fastener on fastener is fastening.
In sum, by adopting above-mentioned technological scheme, when the outward turning of bolt own, to the power that one of them component is outside, realize two component secured together for convenience detach.
Certainly, the present invention is not limited to above-mentioned citing, the technological scheme that it will be apparent to those skilled in the art that, without departing from the spirit or scope of the present invention, make various amendment to the present invention and change in the claims in the present invention and equivalent scope of replacing thereof, then such amendment and change are contained in the present invention.
