[0026] Furthermore, when it is necessary to adjust the boring bar body 3, firstly, disconnect the two second bolts 9 from the inside of the two third threaded grooves 6, then disconnect the two fixing blocks 7 from the corresponding fixing plates 5 respectively. Then, the extension height of the boring bar body 3 can be adjusted upward or downward. After the boring bar body 3 is adjusted, the two second threaded grooves 10 will be aligned with the inside of the two third threaded grooves 6 again. Then, screw the second bolts 9 into the corresponding third threaded grooves 6. The operation process is simple and convenient for adjusting the boring bar body 3.

[0029] Structural Description:

[0030] Mounting base 1: Serves as the basic support component of the entire boring bar, providing a mounting platform for other components. The circular groove 2 at its top provides a guide and support track for the sliding of the boring bar body 3, ensuring stable movement of the boring bar body 3 during adjustment and limiting the movement trajectory of the boring bar body 3, thus guaranteeing the accuracy and stability of the boring bar machining.

[0031] Circular groove 2: It is located at the top of the mounting base 1 and is slidably connected to the boring bar body 3. By cooperating with the adjustment component, the extension height of the boring bar body 3 can be flexibly changed to adapt to the processing requirements of different hole diameters.

[0032] Boring tool body 3: This is the core component for performing boring operations, directly participating in the cutting of the workpiece. It is used to mate with the first bolt 8 to achieve a detachable connection with the fixing block 7, facilitating disassembly and maintenance.

[0033] Fixed plate 5: Fixedly connected to both sides of the mounting base 1, serving as an auxiliary fixation and support. Multiple third threaded grooves 6 are opened inside, which cooperate with the second threaded grooves 10 and the second bolts 9 on the fixed block 7 to fix the fixed block 7, thereby fixing the position of the boring bar body 3 and ensuring that the boring bar body 3 will not shift during the machining process, thus ensuring machining accuracy.

[0034] Third threaded groove 6: During the adjustment process, by tightening or loosening the second bolt 9, the fixing block 7 and the fixing plate 5 can be fixed or separated, thereby controlling the adjustment and fixing of the boring bar body 3.

[0035] Through groove 4: Through groove 4 provides sliding space for fixed block 7, allowing fixed block 7 to move within it, thereby pushing or pulling the boring bar body 3 to slide within the circular slide groove 2, thus adjusting the position of the boring bar body 3.

[0036] Fixed block 7: By sliding in the through groove 4, it drives the boring bar body 3 to move in the circular slide groove 2, thereby adjusting the position of the boring bar body 3. At the same time, the second threaded groove 10 and the first threaded groove 11 opened inside it cooperate with the second bolt 9 and the first bolt 8 respectively to achieve its own fixation and connection with the boring bar body 3.

[0037] Second threaded groove 10: By removing and installing the second bolt 9, the fixing block 7 and the fixing plate 5 can be fixed or separated, thereby controlling the adjustment and fixing of the boring bar body 3.

[0038] Second bolt 9: When tightened, the fixing block 7 is fixed on the fixing plate 5 to stabilize the position of the boring bar body 3; when loosened, the fixing block 7 can slide in the through groove 4 to adjust the position of the boring bar body 3.

[0039] First threaded groove 11: used to realize the detachable connection between the fixing block 7 and the boring bar body 3, so as to facilitate the disassembly and maintenance of the boring bar body 3.

[0040] First bolt 8: By tightening or loosening the first bolt 8, the connection or separation between the fixing block 7 and the boring bar body 3 can be realized, which facilitates the disassembly and installation of the boring bar body 3 and makes maintenance convenient.

[0041] Fourth threaded groove 12: used to realize the detachable connection between the boring bar body 3 and the fixing block 7. When it is necessary to disassemble and maintain the boring bar body 3, the boring bar body 3 can be separated from the fixing block 7 by removing the first bolt 8, so as to easily remove the boring bar body 3.

[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
