[0002] In the field of modern machining, cutting tools are the core tools for material removal and shape shaping. Their performance and applicability directly affect machining efficiency, accuracy and product quality. As an important component of cutting tools, tool holders undertake the key task of connecting tools and machine tools and transmitting power and torque. Their design and characteristics play a vital role in the stability and effectiveness of the entire cutting process.

[0003] With the rapid development of manufacturing technology, machine tools of different types and specifications are constantly emerging to meet diverse processing needs. However, the design of traditional fixed-length tool holders greatly limits their compatibility with various machine tools. Due to the differences in spindle height, table travel, and tool clamping system dimensions of different machine tools, fixed-length tool holders may not be able to meet the tool installation requirements of some machine tools. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of having to store a large number of tool holders of different lengths to meet the requirements of different machining tasks for tool holder length. To this end, we propose a cutting tool with an adjustable tool holder.

[0005] To achieve the above objectives, this application adopts the following technical solution: a cutting tool with an adjustable tool holder, comprising a tool holder body, an inner groove provided inside the tool holder body, a rotating column rotatably connected inside the inner groove, an adjusting rod provided inside the rotating column, a cutting tool body fixedly connected to the side of the adjusting rod away from the tool holder body, adjusting grooves provided on both sides of the rotating column, arc-shaped blocks fixedly connected to both sides inside the inner groove, a push block slidably connected inside the adjusting groove, an insert rod fixedly connected to the side of the push block away from the arc-shaped block, and an insertion hole provided inside the adjusting rod.

[0006] Preferably, the size of the insertion rod is adapted to the size of the insertion hole, and the surface of the insertion rod is inserted into the interior of the insertion hole.

[0007] Preferably, a return spring is fixedly connected to the side of the push block near the insertion rod, and the side of the return spring away from the push block is fixedly connected to the inside of the adjustment groove.

[0008] Preferably, both ends of the adjustment groove are provided with sliding grooves, and both ends of the push block are fixedly connected with sliders, the surface of the sliders being slidably connected to the inside of the sliding grooves.

[0009] Preferably, both sides of the rotating column are provided with shrinkage grooves, and an insertion block is slidably connected inside the shrinkage groove. Both sides of the blade body are provided with insertion holes. A storage spring is fixedly connected to the side of the insertion block near the inside of the shrinkage groove, and the side of the storage spring away from the insertion block is fixedly connected to the inside of the shrinkage groove.

[0010] Preferably, guide grooves are provided at both ends of the shrinkage groove, and guide blocks are fixedly connected to both ends of the insertion block, with the surface of the guide block slidingly connected to the interior of the guide groove.

[0011] Preferably, the inner groove has two annular grooves inside, and two annular blocks are fixedly connected to the outer diameter surface of the rotating column. The surface of the annular blocks is slidably connected to the inside of the annular grooves.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, the operator adjusts the position of the adjusting rod according to the work situation. After adjusting to the appropriate position, the operator rotates the rotating column, causing the rotating column to drive the push block to contact the arc-shaped block.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figures 1-5 As shown, this utility model provides a technical solution: an adjustable cutting tool, including a tool holder body 1, an inner groove 2 inside the tool holder body 1, a rotating column 3 rotatably connected inside the inner groove 2, an adjusting rod 4 inside the rotating column 3, a cutting tool body 5 fixedly connected to the side of the adjusting rod 4 away from the tool holder body 1, adjusting grooves 6 on both sides of the rotating column 3, arc-shaped blocks 7 fixedly connected to both sides inside the inner groove 2, a push block 8 slidably connected inside the adjusting groove 6, an insert rod 9 fixedly connected to the side of the push block 8 away from the arc-shaped block 7, and an insertion hole 10 inside the adjusting rod 4. The operator adjusts the applicable position of the adjusting rod 4 according to the work situation. After adjusting to the applicable position, the operator rotates the rotating column 3, causing the rotating column 3 to drive the push block 8 to contact the arc-shaped block 7. When the push block 8 contacts the thicker end of the arc-shaped block 7, the arc-shaped block 7 pushes the push block 8 to drive the insert rod 9 into the insertion hole 10, fixing the position of the adjusting rod 4 and the cutting tool body 5, thus achieving the adjustment function.

[0022] Reference Figure 4 As shown in this embodiment, the size of the insertion rod 9 is adapted to the size of the insertion hole 10, and the surface of the insertion rod 9 is inserted into the interior of the insertion hole 10. By adapting the size of the insertion rod 9 to the size of the insertion hole 10, the insertion rod 9 can be stably inserted into the insertion hole 10, thereby effectively improving the stability and firmness of the device, avoiding shaking or falling off during use, and further ensuring the normal operation and service life of the device.

[0023] Reference Figure 5 As shown in this embodiment: a return spring 11 is fixedly connected to the side of the push block 8 near the insertion rod 9, and the side of the return spring 11 away from the push block 8 is fixedly connected to the inside of the adjustment groove 6. When the operator pushes the push block 8 to push the insertion rod 9, the push block 8 compresses the return spring 11 to store force, and the insertion rod 9 is inserted into the insertion hole 10 for fixation. When the operator releases the restriction of the push block 8, the insertion rod 9 slides out from the inside of the insertion hole 10 under the action of the return spring 11, which makes it convenient for the operator to adjust the position of the adjustment rod 4, and improves the practicality and flexibility of the device.

[0024] Reference Figure 5As shown in this embodiment: both ends of the adjusting groove 6 are provided with sliding grooves 12, and both ends of the push block 8 are fixedly connected with sliders 13. The surface of the sliders 13 is slidably connected to the inside of the sliding groove 12. When the operator moves the push block 8, the push block 8 drives the sliders 13 to slide inside the sliding groove 12. Through the above settings, the movement of the push block 8 is more stable, avoiding the phenomenon of the push block 8 deviating or shaking during the movement, ensuring the stability and reliability of the overall structure. At the same time, the sliding connection design of the sliders 13 inside the sliding groove 12 also makes the movement of the push block 8 smoother, reducing resistance and friction during the movement, and extending the service life of the overall structure.

[0025] Reference Figure 5 As shown in this embodiment: both sides of the rotating column 3 are provided with shrinkage grooves 14, and the inside of the shrinkage grooves 14 is slidably connected with an insertion block 15. Both sides of the blade body 1 are provided with insertion holes 16. The side of the insertion block 15 closest to the inside of the shrinkage groove 14 is fixedly connected with a storage spring 19, and the side of the storage spring 19 away from the insertion block 15 is fixedly connected to the inside of the shrinkage groove 14. After the operator limits the insertion rod 9 to the insertion hole 10, the position between the insertion block 15 and the insertion hole 16 is set so that the insertion block 15 is parallel to the insertion hole 16. At the same time, under the action of the rebound force of the storage spring 19, the insertion block 15 is quickly pushed into the insertion hole 16, thus limiting the position of the rotating column 3 and preventing the rotating column 3 from rotating on its own.

[0026] Reference Figure 5 As shown in this embodiment: guide grooves 17 are provided at both ends of the shrinkage groove 14, and guide blocks 18 are fixedly connected to both ends of the insertion block 15. The surface of the guide block 18 is slidably connected to the inside of the guide groove 17. When the operator moves the insertion block 15, the insertion block 15 drives the guide block 18 to slide inside the guide groove 17. Through the above settings, the insertion block 15 can be made more stable during movement, avoiding shaking or deviation of the insertion block 15 during movement, thus improving the overall stability and reliability. At the same time, the sliding connection design of the guide block 18 inside the guide groove 17 also makes the movement of the insertion block 15 smoother, reducing resistance and friction during movement, thereby extending the service life.

[0027] Reference Figure 5 As shown in this embodiment: the inner groove 2 has two annular grooves 21 inside, and two ring blocks 20 are fixedly connected to the outer diameter surface of the rotating column 3. The surface of the ring blocks 20 is slidably connected to the inside of the annular grooves 21. When the operator rotates the rotating column 3, the rotating column 3 drives the ring blocks 20 to slide inside the annular grooves 21. Through the above settings, the stability of the rotating column 3 during the rotation process is achieved, effectively preventing the shaking or displacement that may occur during the rotation of the rotating column 3, and ensuring the normal operation of the equipment.

[0028] Working Principle: The operator adjusts the position of the adjusting rod 4 according to the work requirements. After adjustment, the operator rotates the rotating column 3, causing it to drive the push block 8 to contact the arc-shaped block 7. When the push block 8 contacts the thicker end of the arc-shaped block 7, the arc-shaped block 7 pushes the push block 8, causing the insertion rod 9 to be inserted into the insertion hole 10. This fixes the positions of the adjusting rod 4 and the cutting tool body 5, achieving the adjustment function. The matching size of the insertion rod 9 with the insertion hole 10 ensures stable insertion, effectively improving the stability and robustness of the device and preventing shaking or detachment during use, further ensuring... To ensure the normal operation and service life of the device, when the operator pushes the push block 8 to push the insertion rod 9, the push block 8 compresses the return spring 11 to store force, causing the insertion rod 9 to be inserted into the insertion hole 10 for fixation. When the operator releases the push block 8, the insertion rod 9 slides out of the insertion hole 10 under the rebound force of the return spring 11, thus facilitating the operator to adjust the position of the adjusting rod 4, improving the practicality and flexibility of the device. When the operator moves the push block 8, the push block 8 drives the slider 13 to slide inside the slide groove 12. Through the above settings, the movement of the push block 8 is more stable, avoiding the phenomenon of offset or shaking of the push block 8 during movement, ensuring... This ensures the stability and reliability of the overall structure. Furthermore, the sliding connection design of the slider 13 within the groove 12 makes the movement of the push block 8 smoother, reducing resistance and friction during movement and extending the service life of the overall structure. After the operator limits the insertion rod 9 to the insertion hole 10, the position of the insertion block 15 and the insertion hole 16 is adjusted so that the insertion block 15 is parallel to the insertion hole 16. Simultaneously, under the rebound force of the storage spring 19, the insertion block 15 is quickly pushed into the insertion hole 16, limiting the position of the rotating column 3 and preventing it from rotating. When the operator moves the insertion block 15, the insertion block 15 drives the guide block 18 within the guide groove 17. The sliding mechanism of the insert block 15 ensures greater stability during movement, preventing wobbling or deviation and improving overall stability and reliability. Furthermore, the sliding connection design of the guide block 18 within the guide groove 17 facilitates smoother movement of the insert block 15, reducing resistance and friction and extending its service life. When the operator rotates the rotating column 3, the rotating column 3 drives the ring block 20 to slide within the ring groove 21. This design ensures stability of the rotating column 3 during rotation, effectively preventing wobbling or deviation and guaranteeing normal equipment operation.
