Description

Technical Field

[0001] The present invention relates to the technical field of locking nuts, and specifically to an anti-loosening locking nut and its processing technology. Background Technique

[0002] A nut is a screw cap that is screwed together with a bolt or screw rod to play a fastening role. It is an element that must be used in all manufacturing machinery. According to different materials, it is divided into several major types such as carbon steel, stainless steel, and non-ferrous metals (such as copper). A nut is a part that tightly connects mechanical equipment. Through the internal thread, nuts and bolts of the same specification can be connected together.

[0003] When the existing locking nuts are in use, generally a gasket is used to tightly fix the locking nut to achieve the anti-loosening of the locking nut. For the Chinese patent document with the authorized announcement number CN214092678U, it discloses an anti-loosening locking nut, which is improved and optimized for the above problems, that is, through the set arc-shaped card, limit ring, limit bolt, circular ring, magnet ring and convex head. Through the rotation and movement of the limit ring, it is convenient to drive the arc-shaped card to rotate, thereby facilitating the clamping of the locking nut, with high limit stability, and also improving the anti-loosening and anti-vibration effects of the locking nut.

[0049] A processing technology for an anti-loosening lock nut, the processing technology includes the following steps:

[0050] The processing technology of the nut designed in this technical solution is divided into two steps. First, according to the material selection, select alloy steel of appropriate material as the raw material according to the strength grade requirements; anneal the raw material in an annealing furnace to reduce the material hardness and obtain the annealed raw material; first, draw the wire through a wire drawing machine and correct it, and then use a cold heading machine to process it to the required thickness to obtain a nut blank; use a punching machine and a die to punch to process the hexagonal shape and the internal central hole to obtain a punched blank; use a tapping machine to tap the internal thread in the central hole to process the internal thread and obtain a tapped blank; polish the surface and the inner hole of the nut to remove burrs and obtain a polished blank; put the polished blank into a heat treatment furnace for heat treatment to increase the hardness and obtain a heat-treated blank, and obtain the nut body 1 and the connecting ring part 4;

[0051] After that, the fixed ring 5 can be welded to the end of the connecting ring part 4, and the overall nut can be manufactured; and its locking work is mainly realized through the arranged clamping assembly 8. Through the coordinated use of the arranged rubber ring gasket 3, the first auxiliary assembly 6 and the second auxiliary assembly 7, shock absorption protection is carried out for the nut body 1 and the clamping assembly 8. The specific operation of this working process is as follows:

[0052] After tightening the nut body 1 with the screw, the base 2 and the rubber ring gasket 3 provided at one end of the nut body 1 can play a very good shock-absorbing and protective role. Then, it is locked. That is, press the collar 808 so that the convex ring 702 at the bottom end of the collar 808 is inserted into the annular slot 603 on the movable ring 602, and the positioning convex block 701 on the outer side wall of the convex ring 702 is snapped into the positioning card slot 604. At the same time, the arc-shaped driving inclined groove 807 provided on the inner side wall of the collar 808 presses the transmission bar 801, and the transmission bar 801 then pushes the carrier plate 802, so that the clamping plate 804 on the other side of the carrier plate 802 presses and clamps the side wall of the screw. The purpose of setting the auxiliary inclined surface 805 and the anti-slip convex block 806 on one side of the end of the clamping plate 804 in this process is that the clamping plates 804 symmetrically arranged on the carrier plate 802 form a clamping state of clamping against each other under the action of the auxiliary inclined surface 805 and the anti-slip convex block 806, which can ensure the stability of its clamping. When the convex ring 702 enters the annular slot 603, it is necessary to hold the movable ring 602 firmly by hand until the positioning convex block 701 is completely inserted into the positioning card slot 604. At this time, the convex ring 702 presses the second support spring 605, so that the second support spring 605 is in a compressed state. The locking circular groove 703 provided on the positioning convex block 701 is aligned with the locking column 606. Then, push the locking column 606, so that one end of the locking column 606 is snapped into the locking circular groove 703, and the locking column 606 and the locking circular groove 703 are fixed by the mutual attraction of the second magnet 704 and the first magnet 608. The locking and fixing work can be completed. The operation is simple and the use is convenient;

[0053] And in the process of the positioning convex block 701 being snapped into the positioning card slot 604, the movable pins 705 provided on both sides of the positioning convex block 701 are pressed into the receiving groove under the action of the arc-shaped surface at its end and the auxiliary spring 706, so that the auxiliary spring 706 is in a compressed state. The purpose is to improve the stability of the clamping connection between the positioning convex block 701 and the positioning card slot 604;

[0054] For the later loosening work, first separate the locking column 606 from the locking circular groove 703 on the convex ring 702 through the pulling column member 607 to release the locking of the collar 808. At the same time, the collar 808 returns to its initial position under the action of the second support spring 605 in the compressed state, that is, the positioning convex block 701 is separated from the annular slot 603, the positioning convex block 701 is separated from the positioning card slot 604, and the extrusion of the arc-shaped driving inclined groove 807 provided on the inner side of the collar 808 on the transmission bar 801 is released. The transmission bar 801 drives the carrier plate 802 to return to its initial position under the action of the return spring 803, and then the extrusion and clamping of the clamping plate 804 on the side wall of the screw are released. Finally, loosen the nut body 1.

[0055] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
