Specific embodiment
Below in conjunction with attached drawing 1-5, specific embodiment of the present utility model is described in further detail, so that the utility model
Technical solution 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. instructions orientation or position relationship be based on orientation shown in the drawings or position relationship, only
Be the utility model rather than instruction for ease of description or imply signified device or element must have specific orientation,
With specific azimuth configuration and operation, therefore it is not intended that limitation to the utility model.
In addition, the connection between component or fixed form if not otherwise specified in this embodiment, connection or solid
Determine mode can be fixed by bolt commonly used in the prior art or pin fix or axis pin connection etc. modes, therefore, this
It is no longer 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, includes metal outer ring
Disk 1 and the interior quoit 2 inside metal outer ring disk 1 are provided with more than one fixation on metal outer ring disk 1
Hole 3, the direction of the mounting hole 3 is parallel with the central shaft of metal outer ring disk 1, and the diameter of the mounting hole lower part 32 is less than admittedly
Determine the diameter on hole top 31, it 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 made to seem more beautiful, and the mounting hole 3 is included far from metal outer ring disk 1
First mounting hole of mandrel and the second mounting hole close to 1 central shaft of metal outer ring disk, first mounting 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 surface, and the angle of medial surface 11 and central shaft is 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 vertex court of the angle between the medial surface 11 and central shaft of metal outer ring disk 1
To the top of mounting 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
It encloses 1 inside of disk to slip, fixation.The inner surface of the interior quoit 2 is parallel with central shaft, on the interior quoit 2
Unclosed notch 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 gold
When belonging to outer ring disk 1, the notch 22 can be reduced, interior quoit 2 is made more closely to be fixed on the fixed disk body of needs；Make
Interior quoit 2 can be fixed more effectively and make fixation between interior quoit 2 and disk body more secured by metal outer ring disk 1, fixed
More effectively.
Principle explanation：Due to being provided with mounting hole 3, and the diameter on mounting hole top 31 compares mounting hole on metal outer ring disk 1
The diameter of lower part 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 central axes are formed with its central axes is
Equal acute angle and alternate interior angle, and the vertex of angle that the medial surface 11 due to metal outer ring disk 1 is formed with its central axes each other
Towards the direction on mounting hole top 31, metal outer ring disk 1 is fixed on machine body, interior quoit 2 can be prevented from metal
It is slipped in outer ring disk 1, fixation is more secured；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 notch 22 of interior quoit 2 is less and less, and the inner wall of interior quoit 2 can be with needing fixed disk body to be tightly fitted in one
It rises, simple in structure and fixation is easy to use.
Application method：Fixed disk body will be needed to be inserted in inside interior quoit 2 first, and make interior 2 lateral surface of quoit
The smaller 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 mounting hole 3 with bolt or rivet, metal outer ring disk 1 is consolidated
It is scheduled on machine body, both may be used.
The utility model has the technical effect that following aspect：Since the medial surface of metal outer ring disk is tilted for one
Angle between face and medial surface and central shaft is less than 90, but due to metal outer ring disk medial surface and interior quoit it is outer
Side fits, and metal outer ring disk is fixed on machine host, it is possible to quoit in fixed, so that it is fixed positioned at interior metal
Disk body inside circle, it is simple and effective, it is easy to use.
Certainly, it is the representative instance of the utility model more than, in addition to this, the utility model can also have other a variety of
Specific embodiment, all technical solutions formed using equivalent substitution or equivalent transformation all fall within the requires of the utility model protection
Within the scope of.
