Description
Technical Field
The utility model relates to the technical field of tool accessories, in particular to a bolt threading device.
Background
At present, bolts on railway lines at home and abroad are used as main connecting spare and accessory parts on the railway lines, and can play a role in stabilizing and strengthening a track structure. The influence of the operation environment is received in the daily maintenance operation process, and the screw thread on the bolt is difficult to avoid receiving the damage of external force, causes the nut to be unable with the bolt fastening to lose the effect of connection track structure, especially anchor bolt, the change procedure is more loaded down with trivial details. In order to ensure the quality of equipment, the daily maintenance adopts special tools (threading die and sleeve) to thread the damaged screw thread again, and the bolt is tightened again, so that the operation is long in time consumption and low in success rate.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects of the prior art, the utility model aims to provide a bolt wire passing device.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a bolt threading device comprises a threading part and a force application part, wherein the threading part and the force application part are coaxial and integrally formed, and threading threaded holes are formed in inner cavities of the threading part and the force application part along a central axis; the outer diameter of the force application part is smaller than that of the wire passing part; and one end of the wire passing threaded hole, which is far away from the force application part, is communicated with the outside, and the other end of the wire passing threaded hole, which is close to the force application part, is not communicated with the outside.
Furthermore, a plurality of chip removal holes communicated with the wire passing threaded holes are formed in the circumferential direction of the inner cavity of the wire passing part.
Further, the outer diameter of the wire passing part is 48mm, the total height of the wire passing part and the force application part is 41mm, and the height of the wire passing part is 17 mm.
Further, the wire passing part is a cylindrical wire passing part, and the force application part is hexagonal.
The utility model has the beneficial effects that: the bolt threading device can be used as a threading device and a bolt dismounting device, can simultaneously thread a bolt in the process of dismounting the bolt, and is more flexible in use mode. When the bolt maintenance device is applied to bolt maintenance on a railway line, equipment needing to be carried can be reduced, and maintenance efficiency is improved.

Detailed Description
The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed implementation and the specific operation process are provided, but the protection scope of the present invention is not limited to the present embodiment.
The embodiment provides a bolt threading device, as shown in fig. 1-2, which comprises a threading part 1 and a force application part 2, wherein the threading part 1 and the force application part 2 are coaxially and integrally formed, and threading threaded holes 3 are formed in inner cavities of the threading part 1 and the force application part 2 along a central axis; the outer diameter of the force application part 2 is smaller than that of the wire passing part 1; one end of the thread passing threaded hole 3, which is far away from the force application part 2, is communicated with the outside, and the end, which is close to the force application part 2, is not communicated with the outside.
In the embodiment, a plurality of chip removal holes 4 communicated with the thread passing threaded hole 3 are formed in the circumferential direction of the inner cavity of the thread passing part 1. The clearance hole is used to discharge chips generated during cutting of the thread.
In the embodiment, the outer diameter of the thread passing part 1 is 48mm, the total height of the thread passing part 1 and the force applying part 2 is 41mm, and the height of the thread passing part 1 is 17 mm.
In this embodiment, the threading part 1 is a cylindrical threading part, and the force application part 2 is in a hexagonal shape.
The working principle of the bolt threading device is as follows:
when the damaged bolt needs to be repaired, the thread passing part can be installed into the sleeve for use in a conventional mode. When the bolt needs to be disassembled, the thread passing part is sleeved on the bolt, the force application part is manually screwed, or the force application part is fixed by an external electric tool and is electrically screwed, so that the thread passing part is driven to rotate, and the bolt is disassembled by screwing the bolt by the thread passing part. Because the thread passing threaded hole can cut the threads on the surface of the bolt, even if the threads in the bolt and the thread passing threaded hole are not matched initially, the thread passing threaded hole can also cut the threads of the bolt in the rotating process of the thread passing part, so that the threads are matched with each other.
The bolt threading device can be used as a threading device and a bolt dismounting device, and can simultaneously thread the bolt in the process of dismounting the bolt, so that the use mode is more flexible. When the bolt maintenance device is applied to bolt maintenance on a railway line, equipment needing to be carried can be reduced, and maintenance efficiency is improved.
Various corresponding changes and modifications can be made by those skilled in the art based on the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
