Abstract
The invention relates to a magnetic force anti-vibration loosing-proof bolt and nut that includes magnetic guiding bolt and magnetic nut that is formed by a flute nut and a permanent magnet. When the nut screwing on the bolt, the permanent magnet would generate magnetic attraction to the bolt to make the nut and the bolt joint together, if the fasten material is magnetizer, the nut would joint with it tightly. And the nut, the bolt and the fasten material would be joint together, and sharply increase the fastening strength and loosing defend ability. The invention has good anti-vibration loosing-proof ability, simple structure and is material saving.
Description
Technical field
The invention belongs to industrial manufacturer's standard part---fastener areas, relate to a kind of magnetic material, particularly a kind of magnetic force antivibration chek bolt, nut in the tightening technology Application for Field.
Background technique
Screw fastener is one of most widely used accessory, relates to every field such as industry, agricultural, traffic, national defence, daily life.Along with rapid development of science and technology, people are also more and more higher to the requirement of screw, especially at aspects such as locking, antitheft, antivibratioves, for this reason, people have done unremitting effort, have studied many novel bolt, nuts with some function, and obtained gratifying achievement, Chinese patent discloses the innovation and creation of a lot of relevant this respects, and wherein the overwhelming majority all is to propose new idea, new technology, new method from the mechanical realization aspect, but still the end is seen and related to magnetic material application in this respect.
Summary of the invention
The objective of the invention is at above-mentioned reason, the application of a kind of magnetic material in the tightening technology field is provided, be specifically related to a kind of locking bolt of magnetic force antivibration, nut of utilizing.The present invention compared with prior art have the locking Security of antivibration good, can locate arbitrarily, simple in structure, easy manufacturing, easy to use, advance and retreat flexibly, characteristics such as use repeatedly, highly versatile, saving material have also been opened up the frontier that magnetic material is used simultaneously.
To achieve these goals, the present invention by the following technical solutions: a kind of magnetic force antivibration chek bolt of the present invention, nut comprise magnetic conduction bolt and magnetic nut.
Described magnetic conduction bolt is meant and has magnetic property the bolt of (or claiming ferromagnetism).General plain bolt generally has magnetic conductivity.The magnetic property of described magnetic conduction bolt is strong more, and its antivibration anti-loosing effect is good more.
Described magnetic nut is made of a groove nut and a permanent magnet.Described groove nut is that the end at general nut or non-general nut is provided with groove, is provided with a permanent magnet that is complementary with it in described groove.Less than the axial dimension of described magnetic nut, the radial dimension of described groove is less than the radial dimension of described magnetic nut at least for the axial dimension of described groove, and the shape of described groove can be and the corresponding to hexagon of nut shape or other shapes.Described permanent magnet has the geometrical shape that is complementary with described groove, has the geometrical shape that can fill described groove in other words.The inwall of described permanent magnet can be smooth, also can be the internal thread shape.Smooth surface is easy to process, and internal thread shape surface then has better antivibration anti-loosing effect.When the inwall of described permanent magnet is designed to the internal thread shape, then described internal thread should magnetic conduction bolt supporting with it screw thread match, and this internal thread inlet should continue mutually with the internal thread outlet of its joining described groove nut, in other words, after described permanent magnet was installed in the described groove of described groove nut, the internal thread of described permanent magnet should communicate with the internal thread lines of described groove nut.When screwing on described bolt with the described magnetic nut of box lunch, described groove nut and the synchronous precession of described permanent magnetism physical efficiency.
The material of described groove nut can not limit, and promptly can be that permeability magnetic material also can be a non-magnet material.When described groove nut was magnet case, described permanent magnet should magnetize in advance and reinstall described groove and get final product, because magnetic force can be connected as one them securely; On the contrary, if when described groove nut is non-magnetizer, described permanent magnet just must be affixed by modes such as bonding, engaging, injection moulding and described groove nut.
Described permanent magnet comprises various permanent magnets such as neodymium iron boron, ferrite, Nanocomposite magnet and the composite material that comprises a kind of permanent-magnet material at least.
The working principle of a kind of magnetic force antivibration of the present invention chek bolt, nut: when described magnetic nut screws on described magnetic conduction bolt, described permanent magnet on the described magnetic nut will produce magnetic attraction to described magnetic conduction bolt, this magnetic attraction links together described magnetic nut and magnetic conduction bolt as glue, thereby strengthened the linking intensity of described magnetic nut and magnetic conduction bolt widely, made a kind of magnetic force antivibration chek bolt of the present invention, nut have good anti-loosening property and any locating function.Magnetic material makes a kind of magnetic force antivibration chek bolt of the present invention, nut have the function of vibration damping, antivibration again to the absorption of the ripple that shakes.If fastened body is magnet case or is magnet case in the magnetic field range at permanent magnet when contacting with described magnetic nut, described magnetic nut is when fastening described fastened body, described permanent magnet also can produce magnetic attraction to described fastened body simultaneously, thereby magnetic force antivibration chek bolt of the present invention, the antivibration of nut, anti-loosening property further are enhanced.Therefore, it is tubaeform that described magnetic nut can also be designed to its described permanent magnet one end, to improve the further antivibration anti-loosing effect of a kind of magnetic force antivibration chek bolt of the present invention, nut.
A kind of magnetic force antivibration chek bolt of the present invention, nut beneficial effect are to have improved the antivibration anti-loosening property significantly, and have random positioned function.When reaching same fastening strength, a kind of magnetic force antivibration of the present invention chek bolt, the comparable plain bolt of nut, nut reduce material more than 25%.
