Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.
As shown in fig. 1 to 4, the present invention provides a bolt-piercing guide tool, which includes a tapered rod 100 and a guide rod 200, wherein the diameter of the tapered rod 100 is gradually reduced from one end to the other end; one end of the guide rod 200 is fixedly connected to the end of the tapered rod 100 having a larger diameter, and the other end of the guide rod 200 is provided with a screw hole 210 for fixing the bolt 300.
When it is required to pass the bolt 300 through the holes of the two members (the first member 400 and the second member 500), as shown in fig. 3 and 4, the bolt 300 may be first fixed to the threaded hole 210 of the guide rod 200, and then the tapered rod 100 may be sequentially passed through the corresponding holes of the first member 400 and the second member 500, so that the holes of the first member 400 and the second member 500 may be aligned by the constraint of the tapered rod 100, and as the tapered rod 100 and the guide rod 200 are continuously passed through, the bolt 300 connected to the guide rod 200 may be finally passed through the holes of the first member 400 and the second member 500 along with the guide rod 200, thereby achieving the rapid penetration of the bolt 300.
It should be noted that, for convenience of description, the first component 400 and the second component 500 are used for description in this embodiment, and in practical application, a third component or more components may also be provided, which is not described again in this embodiment.
Wherein the minimum value of the diameter of the tapered rod 100 is one third of the diameter of the bolt 300, whereby, when the hole of the first member 400 and the hole of the second member 500 are not completely aligned, the size of the aligned portion between the two holes is smaller than the entire size of the hole, making it difficult for the bolt 300 to independently pass through the two holes; and since the diameter of the end of the tapered rod 100 is small, it can simultaneously pass through the aligned portion between the two holes, and as the tapered rod 100 continues to pass through, it is possible to further adjust the holes of the two members to an aligned state by gradually increasing the size of the tapered rod 100 itself, and when the tapered rod 100 and the guide rod 200 pass through the holes of the two members, it is possible to pass the bolt 300 through the holes of the two members.
Further, the guide rod 200 may be a cylinder, and the diameter of the guide rod 200 may be slightly smaller than the inner diameter of the holes of the first member 400 and the second member 500. After the guide bar 200 is inserted into the holes of the first and second members 400 and 500, the alignment of the holes of the two members can be maintained by the support of the guide bar 200, so that the bolt 300 can be guided into the holes of the two members.
In order to ensure that the connection position of the tapered rod 100 and the guide rod 200 is smooth and without steps so that the tapered rod 100 and the guide rod 200 can smoothly pass through the holes of the two parts, the outer diameter of the guide rod 200 is equal to the maximum value of the diameter of the tapered rod 100.
In order to facilitate the processing and manufacturing of the tapered rod 100 and the guide rod 200, the tapered rod 100 and the guide rod 200 are integrally formed.
In addition, in order to increase the overall strength of the bolt-piercing guide tool, both the tapered rod 100 and the guide rod 200 may be made of steel.
Further, the diameter of the guide rod 200 is 1mm larger than that of the threaded hole 210, so that the guide rod 200 can be ensured to pass through the hole on the component, and a large gap amount generated after the bolt 300 passes through the hole on the component can be avoided.
The embodiment of the utility model provides a bolt perforation guiding tool has realized correcting fast to the relative position in hole and hole, makes the bolt install fast to the part hole after correcting in, has improved equipment maintenance efficiency.
The structure, features and effects of the present invention have been described in detail above according to the embodiment shown in the drawings, and the above description is only the preferred embodiment of the present invention, but the present invention is not limited to the implementation scope shown in the drawings, and all changes made according to the idea of the present invention or equivalent embodiments modified to the same changes should be considered within the protection scope of the present invention when not exceeding the spirit covered by the description and drawings.
