Description
Technical field
The utility model relates to a kind of powerful vibration nut assembly for high speed cutting machine.
Background technique
In existing technology, because high speed filament cutting mechanism exists periodically, cut off and impact, board vibration can cause general anti-loosening fastening nut to lose efficacy and ineffective, and then to skid appear in the wire-drawing effect that affects pulling wheel, cannot pull steel core.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of powerful vibration nut assembly for high speed cutting machine, can be not loosening under the anti-strong vibrational state of high speed cutting machine.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the powerful vibration nut assembly for high speed cutting machine, comprise knurled nut and recessed nut,
Described knurled nut comprises cylinder, an end face of described cylinder has protuberance, described protuberance is the cone with described cylinder concentric, described cone is less than the diameter of described cone cross section as the diameter of whole described knurled nut end face, have the tapped hole through two end face in described knurled nut;
Described recessed nut comprises the cylinder with step hole, described step hole is through two end faces of described cylinder, left section of cross-sectional diameter of described step hole is greater than its right section of cross-sectional diameter, left section of described step hole is cone shape hole, the tapering of described cone shape hole and size match with described cone, right section of cross-sectional diameter of described step hole is identical with described tapped hole cross-sectional diameter, and right section of described step hole has screw thread, and the screw thread in described screw thread and described tapped hole is adaptive.
Further, for strengthening relaxation effect, also comprise locking mechanism, described locking mechanism comprises a plurality of pinning plates and a plurality of pinning nail, and described pinning plate one end has mounting hole, has a plurality of lockholes of arranging continuously on described pinning plate;
Described pinning nail is axially distributed in its outer surface around described recessed nut;
The outer surface of described knurled nut is around the uniform a plurality of Screws of its axis, and described mounting hole is placed on described Screw, and described pinning plate can be around described Screw rotation;
Described lockhole can be placed on described pinning and nail on.
Further, for saving manufacture cost, the cross section of described protuberance is less than the cross section of described knurled nut cylinder.
Further, for ease of processing, described protuberance and described knurled nut cylinder connection part have tool withdrawal groove.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, this nut assembly to loosen antivibration effect extremely strong; Have simple in structure, the advantage such as processing cost is low.

Embodiment
As shown in Figure 1, the utility model provides a kind of powerful vibration nut assembly for high speed cutting machine, comprises knurled nut 1 and recessed nut 2,
Recessed nut 2 comprises the cylinder with step hole, step hole is through two end faces of cylinder, left section of cross-sectional diameter of step hole is greater than its right section of cross-sectional diameter, left section of step hole is cone shape hole 21, the tapering of cone shape hole 21 and size match with cone 11, right section of cross-sectional diameter of step hole is identical with tapped hole cross-sectional diameter, and right section of step hole has screw thread 22, and screw thread 22 is adaptive with the screw thread in tapped hole.
For further strengthening the antivibration relaxation effect of nut assembly, this nut assembly is also provided with locking mechanism, and locking mechanism comprises a plurality of pinning plates 32 and a plurality of pinning nail 33, as shown in Figure 3, pin plate 32 one end and there is mounting hole, pin on plate 32 and there are a plurality of lockholes of arranging continuously 34; Pin nail 33 and be axially distributed in its outer surface around recessed nut 2; The outer surface of knurled nut 1 is around the uniform a plurality of Screws 31 of its axis, and mounting hole is placed on Screw 31, and pinning plate 32 can be around Screw 31 rotation; Lockhole 34 can be placed on and pin on nail 33.
For saving manufacture cost, the cross section of protuberance is less than the cross section of knurled nut 1 cylinder.
For ease of processing, protuberance and knurled nut 1 cylinder connection part have tool withdrawal groove.
The working procedure of this example: as shown in Figure 2, during installation, knurled nut 1 is tightened (cone outwardly) in advance with equipment, then screw in recessed nut 2, cone shape hole 21 contacts direct stress and the axial thrust load producing perpendicular to the conical surface along the conical surface with cone 11, its reaction force acts is in concavo- convex nut 1, 2 conical surface contact position, screw thread stressing conditions acts on the conical surface to double nut to pushing up locking similar its radial component. along with the continuation screw-in of recessed nut 2, stress between the contact conical surface sharply strengthens, produce great friction torque, due to the size of this friction torque only with recessed nut 2 to be screwed into degree relevant, and it is irrelevant with any extraneous factor, therefore anti-loosening property is fine.Concavo-convex nut 1,2 is placed on the lockhole 34 pinning on plate 32 on pinning nail 33 after working good, and can further start relaxation effect like this.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
