Abstract

The invention relates to an anti-loose fastening method of a bolt pair, comprising the following steps: 1, allowing a common bolt to penetrate through the connection screw hole of a member to be connected; 2 locking the bolt by a first nut matched with the thread of the bolt, and screwing down; and 3 locking the bolt continuously by a second nut with the opposite thread direction, the same thread pitch diameter and thread pitch of the first nut, and screwing down. Compared with the traditional method for connecting the bolt pair, the method of the invention can greatly enhance the connection strength, therefore the bolt pair is hardly loosened under the impact of external force.

Description

The secondary locking locking method of a kind of bolt
Affiliated technical field
The present invention relates to the five metals field, particularly, is a kind of method of clamping bolt pair.
Background technique
For fixing of mechanical link, big part adopts the bolt pair to connect.When in no impacting force on the bolt axial direction, frictional force is less between screw thread, nut rotates easily, and because the deformation of rigid pipe is very little, therefore, only rely on the pressuring action of bolt pair and rigid connector, then the screw thread impacting force is less, and frictional force is also little between screw thread, and nut is loosening easily, so the connection for screw retention is had relatively high expectations generally all can increase the bullet pad in the bolt pair.However, still probably loosening when link stands external impacts for a long time, therefore,, generally tighten two nuts at same bolt at the fastening place that has relatively high expectations, nut outside is retrained the nut of inboard, improve fastening reliability.But, although after adopting double nut fastening, its soundness is improved, after external force was impacted simultaneously to double nut, outer nut and inner nut rotated probably simultaneously, finally cause getting loose, therefore, still there is shortcoming in its soundness, is necessary further to take measures, thereby makes the secondary soundness that connects of bolt obtain further to strengthen.
Summary of the invention
For above-mentioned problem, the object of the present invention is to provide the secondary locking locking method of a kind of bolt, this method can make connectivity robustness be improved to a great extent with respect to the secondary connecting means of traditional bolt, makes the bolt pair be difficult to get loose under the impact of external force.
The technical solution adopted for the present invention to solve the technical problems is: the secondary locking locking method of this bolt comprises the steps:
1, adopt plain bolt to penetrate in the connection screw of connected piece;
2, adopt first nut that described bolt is tied down, and tighten with the threads engaged of described bolt;
3, adopt a, effective diameter of thread opposite and the second all equal nut of pitch to continue to tack described bolt, and tighten with the described first nut thread direction.
Further, between described first nut and second nut, put one first bullet pad, with the impacting force between further strengthened thread;
Further, before described step 2, one second bullet pad of cover on described bolt, and then the above first nut of bolt;
Further, before the above second bullet pad of cover, on described bolt, put a plain cushion earlier, and then overlap the above second bullet pad;
Beneficial effect of the present invention is: it is secondary when fastening to adopt this method to carry out bolt, because first nut is opposite with the hand of spiral of second nut, therefore both are in rundown process, its sense of rotation is opposite, equally, in unloading process, the sense of rotation of described first nut and second nut is also opposite, and for the impact of external force, for link usually towards same direction, therefore, non-artificial property external impacts only may make described first nut, second nut rotates along same direction, and can't make two nuts get loose simultaneously this moment, therefore, with respect to the secondary connecting means of traditional bolt, the locking locking method of this screw pair can make connectivity robustness be improved to a great extent, makes the bolt pair be difficult to get loose under the impact of external force.
Description of drawings
Fig. 1 is the enforcement schematic representation of the secondary locking locking method of this bolt.
Embodiment
The present invention is further described below in conjunction with drawings and Examples:
Be illustrated in figure 1 as one embodiment of the present of invention, among this embodiment, the secondary locking locking method of this bolt comprises the steps:
At first, adopt plain bolt 3 to penetrate in the connection screw of connected piece (not shown);
Secondly, on described bolt 3, put one second bullet pad 13;
Once more, on described bolt 3, put first nut 1 with the threads engaged of this bolt 3, described bolt 3 is tied down, and tighten;
Then, on described bolt 3, put one first bullet pad 12;
At last, second nut 2 that adopts a, effective diameter of thread opposite with described first nut, 1 hand of spiral and pitch all to equate continues to tack described bolt 3, and tightens.
Embodiment two
In embodiment two, before the second above-mentioned bullet pad 13, earlier a plain cushion is inserted in described bolt 3, all the other steps are all same as the previously described embodiments, repeat no more.
Adopt the secondary locking locking method of above-mentioned bolt to carry out bolt when secondary fastening, because first nut 1 is opposite with the hand of spiral of second nut 2, therefore both are in rundown process, its sense of rotation is opposite, as shown in Figure 1, dotted arrow is the nut sense of rotation, and solid arrow is the movement direction of nut along bolt.Equally, in unloading process, the sense of rotation of described first nut 1 and second nut 2 is also opposite, and for the impact of external force, for link usually towards same direction, therefore, non-artificial property external impacts only may make described first nut 1, second nut 2 rotate along same direction, can't make two nuts get loose simultaneously this moment, therefore, with respect to the secondary connecting means of traditional bolt, the locking locking method of this screw pair can make connectivity robustness be improved to a great extent, makes the bolt pair be difficult to get loose under the impact of external force.
