DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In order to make the objectives, technical solutions and advantages of the utility model more clear and understandable, the following further describes the utility model in detail with reference to the accompanying drawings and embodiments.

[0027] The fine-tuning boring tool assembly has a boring head 1 and a floating head 2;

[0028] As Figures 1 to 4 shown, the boring head 1, the boring head 1 is the core part of the boring tool assembly, its top can be connected to a lathe, and an activity groove 11 is opened at the bottom of the boring head 1;

[0029] The floating head 2, a cutting tool head is installed at a bottom corner of the floating head 2, and the floating head 2 is driven by the boring head 1 to rotate to make the cutting tool head perform cutting. The floating head 2 is provided with an upwardly protruding activity bar 21, and the activity bar 21 is slidably connected inside the activity groove 11, allowing a certain relative movement space between the floating head 2 and the boring head 1, so as to adjust the inner diameter of the cutting hole;

[0030] The upper rack 3, an upper rack 3 is fixedly connected inside the activity groove 11, and it is a strip-shaped structure with teeth;

[0031] The lower rack 4, an inner cavity 22 is provided inside the activity bar 21, and a lower rack 4 is fixedly connected inside the inner cavity 22, similar to the upper rack 3;

[0032] The moving seat 5, a moving seat 5 is slidably connected between the floating head 2 and the inner cavity 22 of the activity bar 21, and this slidable connection allows the moving seat 5 to adjust its position during the adjustment process;

[0033] The gear 6, a gear 6 is rotatably connected inside the moving seat 5, and the upper and lower sides of the gear 6 are respectively meshed and connected with the upper rack 3 and the lower rack 4. When the gear 6 rotates, due to the meshing relationship with the upper rack 3 and the lower rack 4, it can drive both of them to move simultaneously, so as to realize the position adjustment of the boring head 1;

[0034] The partition plate 7, a partition plate 7 is fixedly connected inside the inner cavity 22 of the activity bar 21, and the partition plate 7 divides the space of the inner cavity 22 and provides an interface threadedly connected with the adjusting sleeve 8;

[0035] The adjusting sleeve 8, an adjusting sleeve 8 is threadedly connected inside the partition plate 7, one end of the adjusting sleeve 8 is rotatably connected with the moving seat 5, and by rotating the adjusting sleeve 8, the relative position between it and the partition plate 7 can be changed, so as to drive the moving seat 5 to move;

[0036] As Figures 1 to 4 , a sliding groove 12 is opened inside the boring head 1 and above the activity groove 11, and the sliding groove 12 is communicated with the activity groove 11. A sliding bar 31 is provided at the top of the upper rack 3, and the sliding bar 31 is slidably connected inside the sliding groove 12. The sliding connection not only ensures the stability of the upper rack 3 during movement, but also restricts its movement to only a specific direction, thereby improving the accuracy and reliability of the adjustment;

[0037] As Figures 1 to 4, the cross-sections of the movable slot 11 and the sliding slot 12 are both arranged in an inverted trapezoidal shape. The cross-section of the sliding bar 31 matches the cross-section of the sliding slot 12, and the cross-section of the movable bar 21 matches the cross-section of the movable slot 11. The inverted trapezoidal design makes the top opening of the slot wider and the bottom narrower, facilitating the insertion and positioning of the movable bar 21 and the sliding bar 31 and making it difficult for them to separate;

[0038] As Figures 1 to 4 , a regulating rod 23 is rotatably connected inside the inner cavity 22 of the floating head 2. One end of the regulating rod 23 is slidably inserted into the regulating sleeve 8. The regulating rod 23 is prism-shaped. When the regulating rod 23 rotates, the end slidably inserted into the regulating sleeve 8 will drive the regulating sleeve 8 to rotate accordingly.

[0039] As Figures 1 to 4 , a threaded rod 13 is rotatably connected inside the boring head 1, and one end of the threaded rod 13 is threadedly connected inside the sliding bar 31. The sliding bar 31 of the lower rack 4 is fixed to the boring head 1 through the threaded rod 13, and the sliding bar 31 is adjusted by rotating the threaded rod 13.

[0040] As Figures 1 to 4 , grooves 51 are provided at both the top and bottom of the moving seat 5. The grooves 51 are respectively slidably connected to the outer sides of the upper rack 3 and the lower rack 4. These grooves 51 are designed to match the outer shapes of the upper rack 3 and the lower rack 4, making the movement of the regulating sleeve 8 smoother.

[0041] As Figures 1 to 4 , one end of the inner cavity 22 of the movable bar 21 and one end of the sliding slot 12 are both open. This opening design facilitates observing the operating state of the internal components.

[0042] The working principle of the fine-tuning boring tool assembly provided by the present utility model is as follows:

[0043] When it is necessary to greatly adjust the relative position between the boring head 1 and the floating head 2, the regulating rod 23 can be rotated. One end of the regulating rod 23 is slidably inserted into the regulating sleeve 8, and the regulating sleeve 8 is threadedly connected inside the partition plate 7. As the regulating rod 23 rotates, the regulating sleeve 8 rotates and moves relative to the partition plate 7, thereby changing the distance between the partition plate 7 and the moving seat 5. Since a gear 6 is rotatably connected inside the moving seat 5, and the upper and lower sides of the gear 6 are respectively meshed with the upper rack 3 and the lower rack 4, when the distance between the partition plate 7 and the moving seat 5 changes, the moving seat 5 drives the gear 6 to move along the lower rack 4. Due to the meshing relationship between the gear 6 and the upper rack 3 and the lower rack 4, the movement of the gear 6 will cause the upper rack 3 to move as well. Since the upper rack 3 is fixed inside the movable slot 11, the movement of the upper rack 3 actually drives the movement of the entire boring head 1; in this way, the relative position between the boring head 1 and the floating head 2 can change greatly to meet different processing requirements;

[0044] When minor adjustments are required, the threaded rod 13 can be rotated. One end of the threaded rod 13 is threadedly connected inside the slider 31, and the slider 31 is slidably connected inside the chute 12. Moreover, the slider 31 is located at the top of the upper rack 3. As the threaded rod 13 rotates, the slider 31 slides inside the chute 12. Since the slider 31 is fixedly connected to the upper rack 3, the sliding of the slider 31 will cause the upper rack 3 to move within a small range. Since the lower rack 4 is fixed inside the inner cavity 22 of the movable bar 21, and the movable bar 21 is fixedly connected to the floating head 2, the relative position between the lower rack 4 and the floating head 2 remains unchanged. When the upper rack 3 moves, since the gear 6 meshes with both the upper rack 3 and the lower rack 4, and the distance between the partition 7 and the moving seat 5 does not change, that is, the axial position of the gear 6 does not change, the gear 6 will not rotate but is restricted to a fixed position. At this time, the boring head 1 undergoes a small displacement relative to the lower rack 4 and the floating head 2, thereby achieving a minor adjustment of the relative position between the boring head 1 and the floating head 2;

[0045] By combining these two adjustment methods, the fine-adjustment boring tool assembly can precisely control the relative position between the boring head 1 and the floating head 2 to meet the requirements of different machining precisions.

[0046] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
