[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides, for example Figures 1-5The diagram illustrates a modular connection mechanism for an adjustable-length honing rod, comprising: a first honing rod 1, the first honing rod 1 being hollow inside, and a second honing rod 2 slidably connected inside the first honing rod 1; the second honing rod 2 having a connecting structure on its exterior. This connecting structure facilitates the adjustment of the honing rod's length.

[0031] The connecting structure includes a first connecting block 3, a second connecting block 4, a third connecting block 5, and a connecting bolt 10. The exterior of the first connecting block 3 is fixedly connected to the exterior of the second honing rod 2, and the side of the first connecting block 3 is fixedly connected to the side of the second connecting block 4. The side of the second connecting block 4 is fixedly connected to the side of the third connecting block 5. The interior of the second honing rod 2 has a first connecting hole 6, and the interior of the first honing rod 1 has a second connecting hole 9. The connecting bolt 10 is inserted into the interior of the first connecting hole 6 and the second connecting hole 9. The outer wall of the first honing rod 1 has a first connecting groove 7, and the inner wall of the first honing rod 1 has a second connecting groove 8. The first connecting groove 7 is inserted into the third connecting block 5, and the second connecting groove 8 is inserted into the first connecting block 3. The connection structure adopts a multi-level connection method consisting of a first connecting block 3, a second connecting block 4, and a third connecting block 5. Since the first connecting groove 7 is inserted into the third connecting block 5, and the second connecting groove 8 is inserted into the first connecting block 3, the contact area and firmness of the connection are increased, effectively preventing the connection from loosening due to vibration and impact during the processing, and ensuring the accuracy and stability of the honing process.

[0032] In addition, there are multiple first connecting holes 6 and multiple second connecting holes 9, and the spacing between the multiple first connecting holes 6 and multiple second connecting holes 9 is equal. The connecting bolt 10 passes through and extends to the outside of the first honing rod 1, and the external thread of the connecting bolt 10 is connected to a nut. When it is necessary to adjust the length of the honing rod, the nut can be rotated in the opposite direction to separate the nut from the connecting bolt 10. Then, the connecting bolt 10 can be pulled out to separate the connecting bolt 10 from the first connecting hole 6 and the second connecting hole 9. Then, according to the processing needs on site, the length of the second honing rod 2 can be adjusted so that the first connecting hole 6 and the second connecting hole 9 coincide. Then, the connecting bolt 10 is inserted and locked with the nut. This allows for quick adjustment of the length of the honing rod to meet the needs of workpieces with different processing hole diameters and depths, greatly improving the adaptability and efficiency of honing processing.

[0033] Finally, a connecting rod 11 is fixedly connected to the end of the second honing rod 2 furthest from the first honing rod 1. A connecting sleeve 12 is inserted into the outside of the connecting rod 11. A fixing rod 13 is fixedly connected to the side of the connecting sleeve 12. A honing sleeve 15 is threadedly connected to the outside of the fixing rod 13. Multiple honing strips 16 are provided on the outside of the honing sleeve 15. A fixing bolt 14 is inserted into the outside of the connecting sleeve 12. The outside of the fixing bolt 14 is threadedly connected to the inside of the connecting rod 11. A positioning bolt 17 is inserted into the inside of the honing sleeve 15. The outside of the positioning bolt 17 is threadedly connected to the inside of the fixing rod 13. The inner diameter of the workpiece can be honed using the honing strips 16. The fasteners such as the connecting bolt 10, fixing bolt 14, and positioning bolt 17 make the length adjustment of the honing rod and the replacement of the end parts simple and quick. The modular design is easy to master, and the connection relationship between each component is clear, which facilitates maintenance personnel to quickly locate and solve problems, thus improving the maintainability of the equipment.

[0034] Working principle: When the length of the honing rod needs to be adjusted, the nut can be rotated in the opposite direction to separate the nut from the connecting bolt 10. Then, the connecting bolt 10 can be pulled out to separate it from the first connecting hole 6 and the second connecting hole 9. Then, the length of the second honing rod 2 can be adjusted according to the processing requirements on site, so that the first connecting hole 6 and the second connecting hole 9 coincide. Then, the connecting bolt 10 is inserted and locked with the nut. This allows for quick adjustment of the honing rod length to meet the needs of workpieces with different processing hole diameters and depths, greatly improving the adaptability and efficiency of honing. The connection structure adopts a multi-stage connection method of the first connecting block 3, the second connecting block 4, and the third connecting block 5. Since the first connecting groove 7 is inserted into the third connecting block 5, and the second connecting groove 8 is inserted into the first connecting block 3, the contact area and firmness of the connection are increased, effectively preventing the connection from loosening due to vibration and impact during processing, and ensuring the accuracy and stability of honing.
