Embodiment
Below in conjunction with accompanying drawing 1-5, the embodiment of the present invention is described in further detail, so that technical solution of the present invention
It is more readily understood and grasps.
In the present embodiment, it is to be understood that term " centre ", " on ", " under ", " top ", " right side ", " left end ",
" top ", " back side ", " middle part ", etc. instruction orientation or position relationship be based on orientation shown in the drawings or position relationship, only
It is must have specific orientation, Yi Te for the ease of the description present invention, rather than the device or element of instruction or hint meaning
Fixed azimuth configuration and operation, therefore be not considered as limiting the invention.
In addition, the connection between part or fixed form if not otherwise specified in this embodiment, it is connected or solid
It can be to be fixed by bolt commonly used in the prior art or pin is fixed to determine mode, or the mode such as bearing pin connection, therefore, at this
No longer it is described in detail in embodiment.
With reference to figure 1-5, a kind of mechanical fastening device, for disk body is fixed on machine body, include metal outer ring
Disk 1, and the interior quoit 2 inside metal outer ring disk 1, more than one fixation is provided with metal outer ring disk 1
Hole 3, the direction of the fixing hole 3 is parallel with the central shaft of metal outer ring disk 1, and the diameter of the fixing hole bottom 32 is less than admittedly
Determine the diameter on hole top 31, can either metal outer ring disk 1 be fixed on machine body and bolt or riveting by rivet with bolt
Nail can be inlaid into metal outer ring disk 1, it is seemed more attractive in appearance, and the fixing hole 3 is included away from metal outer ring disk 1
First fixing hole of mandrel and the second fixing hole close to the central shaft of metal outer ring disk 1, first fixing hole and second are fixed
Hole is arranged alternately, and can be fixed on metal outer ring disk 1 is stronger on machine body.The medial surface of metal outer ring disk 1
11 be an inclined plane, and medial surface 11 and the angle of central shaft are less than 90 °, the medial surface 11 of metal outer ring disk 1 with it is interior
The lateral surface 21 of quoit 2 fits, the summit court of the angle between the medial surface 11 and central shaft of metal outer ring disk 1
To the top of fixing hole 3, angle and interior quoit 2 between the medial surface 11 and central shaft of metal outer ring disk 1 it is interior
The angle that side 21 and central shaft are formed alternate interior angle each other, after fixed metal outer ring disk 1, interior quoit 2 will not be outside metal
Enclose the inside of disk 1 to slip, fixation.The inner surface of the interior quoit 2 is parallel with central shaft, on the interior quoit 2
Unclosed breach 22 is provided with, metal outer ring disk 1 is formed with interior quoit 2 and is interference fitted, and interior quoit 2 is inserted in into gold
When belonging to outer ring disk 1, the breach 22 can be reduced, interior quoit 2 is more closely fixed on the fixed disk body of needs；Make
Interior quoit 2 can more effectively be fixed and make fixation between interior quoit 2 and disk body more firm by metal outer ring disk 1, fixed
More effectively.
Principle explanation：Due to being provided with fixing hole 3 on metal outer ring disk 1, and the diameter on fixing hole top 31 compares fixing hole
The diameter of bottom 32 is big, can use bolt or rivet that metal outer ring disk 1 is fixed on machine body, due to metal outer ring
The angle that the angle and the lateral surface 21 of interior quoit 2 that the medial surface 11 of disk 1 is formed with its axis are formed with its axis is
Equal acute angle and alternate interior angle, and the summit of the medial surface 11 due to metal outer ring disk 1 and the angle of its axis formation each other
Towards the direction on fixing hole top 31, metal outer ring disk 1 is fixed on machine body, interior quoit 2 can be prevented from metal
Slipped in outer ring disk 1, fixation is more firm；Due to setting jagged 22, and interior quoit 2 and metal outer ring disk 1 on interior quoit 2
Interference fit is formed, after metal outer ring disk 1 is fixed on machine body, metal outer ring disk 1 can be tightly placed on interior quoit 2, made
The breach 22 of interior quoit 2 is less and less, and the inwall can of interior quoit 2 is tightly fitted in one with needing by fixed disk body
Rise, simple in construction and fixation is easy to use.
Application method：It will need to be inserted in inside interior quoit 2 by fixed disk body first, and make the interior lateral surface of quoit 2
The less side of 21 diameters outwardly, then by 1 set of metal outer ring disk on the lateral surface 21 of interior quoit 2, and makes metal outer ring
The side that the medial surface 11 of disk 1 is relatively large in diameter outwardly, finally passes through fixing hole 3 with bolt or rivet, metal outer ring disk 1 is consolidated
It is scheduled on machine body, both may be used.
The technology of the present invention effect major embodiment is in the following areas：Due to metal outer ring disk medial surface for an inclined plane and
Angle between medial surface and central shaft is less than 90, and the lateral surface phase of the medial surface due to metal outer ring disk and interior quoit
Fitting, metal outer ring disk is fixed on machine main frame, it is possible to quoit in fixed, so that it is fixed inside interior quoit
Disk body, it is simple and effective, it is easy to use.
Certainly, the above is the representative instance of the present invention, and in addition, the present invention can also have other a variety of specific implementations
Mode, all technical schemes formed using equivalent substitution or equivalent transformation, is all fallen within the scope of protection of present invention.
