Optionally, the threaded guide sleeve 1 is a hollow cylindrical sleeve, and the front end of the threaded guide sleeve 1 is plugged by a plug 7.
Further, the rear end of the threaded guide sleeve 1 is axially provided with a butt joint 4 which is matched with the shape of the guide shaft 6, and the front end of the guide shaft 6 is inserted into the butt joint 4 and can move axially but cannot rotate.
In a specific example, the guide shaft 6 is a hexagonal guide shaft, and the docking port 4 is a hexagonal docking port; correspondingly, the assembly hole 8 at the front end of the positioning bolt 2 is also a hexagonal hole.
Optionally, a spring 5 is assembled inside the threaded guide sleeve 1, one end of the spring 5 is supported on a plug 7, and the other end is connected with the guide shaft 6.
In order to facilitate the butt joint during assembly, a permanent magnet 9 matched with the end part of the guide shaft 6 is arranged in the assembly hole 8.
When the invention is installed, the threaded guide sleeve 1 and the positioning bolt 2 are installed step by step, the guide shaft 6 is attracted by the permanent magnet 9 for connection during pre-tightening, and then the positioning bolt 2 is quickly screwed.
The technical features of the present invention are further described below.
In order to increase the guiding function of the bolt rod, the structure of the threaded guiding sleeve 1 is designed in the scheme, and as shown in fig. 1 and 2, the front end of the threaded guiding sleeve 1 is provided with a section of external thread 3, for example, 5-8 pitches; the guide shaft is a hollow cylindrical sleeve, a through hole is formed in the hollow cylindrical sleeve, but a hexagonal butt joint is processed at the rear end of the hollow cylindrical sleeve for matching with the guide shaft 6 so as to meet the installation, positioning and guiding of the hexagonal guide shaft.
The positioning bolt 2 has the external structure basically consistent with that of the existing bolt, and is externally provided with threads, and the difference is that a hexagonal assembly hole 8 is machined at the front end of the positioning bolt 2 along the axial direction, a permanent magnet 9 is built in, and the threaded guide sleeve 1 and the positioning bolt 2 are combined through a guide shaft 6 to realize integral screwing.
For the continuity of the screw thread after butt joint, an elastic adjusting device is designed, and the axial distance of the guide shaft is dynamically adjusted through a spring 5 arranged in the screw thread guide sleeve 1, so that the requirement of the continuity of the screw thread when the screw thread guide sleeve and the positioning bolt 2 are screwed together is met, and the requirement of rapid screwing is realized. When the hexagonal guide shaft is combined, the connection adjustment of the thread is critical, the adjustment allowance of the thread is dynamically controlled by reasonably designing the part structure and the dimensional tolerance of the spring 5 and the guide shaft, the problem of thread conflict after the split bolt is combined is solved, and the split bolt can be quickly screwed.
The work piece installation process by using the invention is as follows:
(1) one end of the threaded guide sleeve with the external thread 3 is screwed into the threaded hole on the mounting surface, and the other end of the threaded guide sleeve replaces the traditional mounting guide pin for guiding.
(2) And the other end of the threaded guide sleeve is used as a guide to quickly guide and position the workpiece to the corresponding position of the mounting surface.
