SUMMERY OF THE UTILITY MODEL
Utility model purpose: the anti-loose bolt with the interference fit for the mechanical part combination has good auxiliary performance without using an auxiliary element for fastening assistance.
The technical scheme is as follows: an interference fit anti-loose bolt for a mechanical part combination comprises a bolt.
Wherein, the bolt comprises a stud and a screw head. The middle part of the stud is provided with an interference part.
The utility model discloses a locking bolt of interference fit for machine part combination mainly includes the bolt. The bolt consists of a stud and a screw head. The middle part of the stud is provided with an interference part. Be equipped with one end interference portion in the middle part of the double-screw bolt, in the use, when using the bolt to fasten, when the interference portion of internal thread portion and this bolt combines each other, can effectual emergence interference fit, accurate interlock is in the same place, is difficult to drop.
Further, the interference part and the stud are integrally formed to form the interference fit anti-loose bolt for the mechanical part combination. As the utility model discloses a preferably, when carrying out bolt production, bolt and interference portion process from the material of a completion and form, the time bolt can effectually play interference fit, and can not take place the problem that interference portion damaged.
Further, in the above-mentioned interference fit anti-loose bolt for the mechanical part combination, the outer diameter of the thread on the interference portion is 1.2 mm larger than the outer diameter of the thread of the stud, and the inner diameter of the thread of the interference portion is 0.6 mm larger than the inner diameter of the thread of the stud. As the utility model discloses a preferred, the big 1.2 millimeters of external diameter of screw on interference portion ratio double-screw bolt, the big 0.6 millimeters of internal diameter of screw can obtain better interference fit, simultaneously, does not influence the use.
Furthermore, the bolt for interference fit locking of the mechanical part combination further comprises a screw head fixing groove. The screw head fixing groove is formed in the screw head and is located at the top of the screw head. As the utility model discloses a preferably, be equipped with a spiral shell head fixed recess at the top of spiral shell head, can conveniently be when fastening the fastening mode of the multiple difference of use that can be more convenient, can twist the spiral shell head, also can twist spiral shell head regulation recess and fasten.
Further, in the above-mentioned interference fit anti-loose bolt for mechanical part combination, one end of the stud far from the screw head is tapered. As the utility model discloses a preferred, the other end of double-screw bolt is the toper, and the taper bolt can or better fixity performance under specific service environment.
The technical scheme shows that the invention has the following beneficial effects: the utility model discloses a locking bolt of interference fit for machine part combination mainly includes the bolt. The bolt consists of a stud and a screw head. The middle part of the stud is provided with an interference part. The middle part of the stud is provided with an interference part at one end, when the stud is used for fastening, when the internal thread part is combined with the interference part of the stud, the interference fit can be effectively generated, the internal thread part is precisely occluded together and is not easy to fall off, when the stud is produced, the stud and the interference part are processed from a finished material, the interference fit can be effectively realized by the stud, the problem of damage of the interference part can not be generated, the interference part is 1.2 mm larger than the external diameter of the thread on the stud, the internal diameter of the thread is 0.6 mm larger, the better interference fit can be obtained, meanwhile, the use is not influenced, the top of the stud is provided with a stud fixing groove, various different fastening modes can be conveniently used when the stud is fastened, the stud can be screwed, the specified groove of the stud can also be used for fastening, the other end of the stud is conical, the taper bolt can achieve or obtain better fixing performance under a specific use environment.
