In order to solve the problem that the vice performance of bolt is poor among the prior art, this application provides a bolt is vice and motor.
In the present application, the motor has a bolt pair. Of course, the bolt pair in the application can also be applied to other mechanical equipment.
As shown in fig. 1 to 4, the bolt pair in the present application includes a nut 10, a bolt 20, and an anti-loosening element 30. The nut 10 is provided with an internal thread 12, the nut 10 is also provided with at least one anti-loosening hole 11, and the anti-loosening hole 11 penetrates through the side wall of the nut 10; the bolt 20 is provided with a head 21 and a stud 22 which are connected, the stud 22 is provided with a threaded section 221 matched with the internal thread 12, and at least one anti-loosening groove 23 is formed in the threaded section 221; the first end of the anti-loosening member 30 can extend into the anti-loosening groove 23 through the anti-loosening hole 11, and the second end of the anti-loosening member 30 is located outside the anti-loosening hole 11.
When the bolt pair with the structure is used, the bolt pair is provided with the anti-loosening element 30, so after the bolt 20 and the nut 10 are screwed and assembled, the anti-loosening element 30 can enter the anti-loosening groove 23 of the bolt 20 through the anti-loosening hole 11 of the nut 10 and limit the relative rotation between the nut 10 and the bolt 20, the nut 10 and the bolt 20 can be prevented from being loosened after being assembled, and the nut 10 and the bolt 20 are prevented from being subjected to large impact. And since the bolt 20 and the nut 10 are not damaged during the process of installing the looseness prevention member 30, it is possible to reuse after the nut 10 and the bolt 20 are disassembled. Thereby effectively improving the service performance of the bolt pair. And when overhauing the vice equipment of using the bolt in this application, can reduce the assemble duration who overhauls the in-process effectively to improve maintenance efficiency.
Specifically, the anti-loosening groove 23 and the first end of the anti-loosening element 30 have a mounting gap therebetween, and the mounting gap is greater than or equal to 0.1 mm and less than or equal to 0.3 mm. By such an arrangement, when the locking member 30 is installed inside the locking groove 23, friction between the locking member 30 and the locking groove 23 can be effectively reduced, thereby reducing damage of the locking member 30 to the locking groove 23 and the bolt 20 during assembly of the bolt pair. At the same time, it is also possible to effectively prevent the generation of looseness between the bolt 20 and the nut 10.
Specifically, the threaded section 221 extends from one end of the stud 22 away from the head 21 to the head 21, and the length direction of the anti-loosening groove 23 is the same as the axial direction of the stud 22. The purpose of this arrangement is to arrange the anti-loosening groove 23 in the length direction of the bolt 20, and since the position of the nut 10 on the bolt 20 varies depending on the use situation when the bolt pair is assembled to the mechanical equipment, this arrangement ensures that the anti-loosening elements 30 can enter the anti-loosening groove 23 through the anti-loosening holes 11 within a certain length range.
Optionally, one end of the anti-loosening groove 23 is communicated to one end of the stud 22 away from the head 21; or the end of the anti-loosening groove 23 is spaced from the end of the stud 22 remote from the head 21.
In one embodiment of the present application, as shown in FIG. 2, an end of the anti-loosening groove 23 communicates with an end of the stud 22 remote from the head 21. The purpose of this setting is that, in the process of processing the bolt pair in this application, can reduce the processing degree of difficulty of bolt 20 effectively, improve the machining efficiency of bolt 20.
Specifically, since the bolt pair is generally subjected to a large impact shock, it is necessary to prevent the loosening prevention member 30 from falling off the nut 10, and therefore, the diameter of the loosening prevention hole 11 may be set smaller than the width of the loosening prevention groove 23. Therefore, the anti-loosening element 30 can not fall off after being impacted and vibrated, and the friction between the anti-loosening element 30 and the bolt 20 can be effectively reduced, so that the strength of the bolt 20 is ensured, and the service performance of the bolt pair is further improved.
Specifically, the groove depth of the anti-loosening groove 23 is larger than the thread height of the thread section 221. Through such an arrangement, when the locking member 30 is accidentally contacted with the locking groove 23, the contact area between the locking member 30 and the locking groove 23 can be effectively increased, so that the damage of the locking member 30 to the bolt 20 is reduced, and the locking groove 23 can be effectively prevented from being deformed. On the other hand, the arrangement can effectively reduce the processing difficulty of the anti-loosening groove 23, thereby improving the production efficiency of the bolt pair.
Specifically, the locking piece 30 is screwed with the hole wall of the locking hole 11. By means of the arrangement, the stability of connection of the anti-loosening element 30 with the bolt 20 and the nut 10 can be effectively guaranteed, and the anti-loosening element 30 can be conveniently assembled and disassembled, so that the bolt pair can be repeatedly used.
In the present application, the locking member 30 is a screw, and after the screw is assembled with the locking hole 11 in place, a first end of the screw extends into the locking groove 23, and a second end of the screw stops at the outer circumferential surface of the nut 10. By means of the arrangement, an existing standard part, namely a screw can be selected as the anti-loosening part 30, and therefore machining processes of the bolt pair are reduced. And after the bolt pair is assembled, the second end of the screw is stopped at the outer circumferential surface of the nut 10, so that the purpose is to facilitate the removal of the anti-loosening element 30 when the bolt pair is disassembled, and also to prevent the first end of the screw from contacting the bottom surface of the anti-loosening groove 23 due to impact shock, thereby preventing the first end of the screw from extruding the bottom surface of the anti-loosening groove 23.
Specifically, when the nut 10 is tightened to the threaded section 221 of the bolt 20, the position where the nut 10 is tightened to the bolt 20 may be different due to different use cases. Therefore, in order to ensure that the anti-loosening holes 11 of the nut 10 can be aligned with the anti-loosening grooves 23 of the bolt 20, a plurality of anti-loosening grooves 23 may be provided, the anti-loosening grooves 23 are arranged at intervals along the circumferential direction of the stud 22, and one anti-loosening hole 11 is provided; or a plurality of anti-loosening holes 11 are arranged at intervals along the circumferential direction of the nut 10, and one anti-loosening groove 23 is formed. Thereby ensuring that the locking member 30 can smoothly enter the locking groove 23 through the locking hole 11.
The projection of the nut 10 in the axial direction is a polygon, and the width of the anti-loosening groove 23 and the diameter of the anti-loosening hole 11 are both smaller than the side length of any side in the polygon.
And in the present application, the nut 10 is a hexagonal nut 10.
In a specific embodiment of the application, the bolt pair is an M20 bolt pair, 6 anti-loosening grooves are uniformly formed in an M20X55 stud, the width of each anti-loosening groove is 3.5mm, the depth of each anti-loosening groove is 3mm, the length of each anti-loosening groove is 55mm, and a threaded through hole of the M3 is machined in the center of one of six faces of a hexagon nut of the M20. After the bolt pair of M20 is installed, the nut and the bolt are limited by the bolt of M3X8, so that the relative rotation movement of the nut and the stud is limited, and the purpose of preventing looseness is achieved.
From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects:
1. the reliability of the connection between the nut 10 and the bolt 20 is effectively improved;
2. the reliability of the operation of mechanical equipment is improved;
3. the time for maintaining the equipment is reduced, and the production efficiency is effectively improved.
