[0001] This utility model relates to the field of thread cutting tool technology, and in particular to a thread cutting tool with a multi-functional tool holder. Background Technology

[0002] In the field of machining, threading is a common and crucial process, widely used in the manufacturing of various mechanical parts. In order to meet the machining needs of different thread specifications, machining depths and complex working conditions, the design and performance optimization of threading tools and their matching tool holders have always been the focus of industry research.

[0003] Currently, the tool holders commonly used in the market are mostly connected to thread cutting tools using traditional fixed structures, such as interference fits, key connections, or simple screw fastening. While these connection methods can ensure the stability of the connection between the tool and the tool holder to a certain extent, they bring great inconvenience when it is necessary to change tools to adapt to different machining tasks. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of not being able to quickly change the cutting head according to different processing conditions. To this end, we propose a multi-functional tool holder threading tool.

[0005] To achieve the above objectives, this application adopts the following technical solution: a multi-functional threading 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, a threading tool body disposed inside the rotating column, adjustment grooves provided on both sides of the rotating column, a push block slidably connected inside the adjustment groove, a plug rod fixedly connected to the side of the push block near the adjustment groove, arc blocks fixedly connected to both sides inside the inner groove, and several slots provided on both sides of the threading tool body.

[0006] Preferably, the inner wall of the inner groove is provided with two annular grooves, and two annular blocks are fixedly connected to the outer diameter surface of the rotating column, with the surface of the annular blocks slidingly connected to the interior of the annular grooves.

[0007] Preferably, the size of the insert rod is adapted to the size of the slot, and the surface of the insert rod is inserted into the interior of the slot.

[0008] Preferably, a buffer pad is installed at the bottom of the inside of the tool holder body.

[0009] Preferably, a return spring is fixedly connected to the bottom of the inner groove, and the top of the return spring is fixedly connected to the bottom of the ring block.

[0010] Preferably, both ends of the adjustment groove are provided with sliding grooves, and both ends of the push block are fixedly connected with sliding blocks, and the surface of the sliding block is slidably connected to the inside of the sliding groove.

[0011] Preferably, a storage spring is fixedly connected to the side of the push block near the insertion rod, and the side of the storage spring away from the push block is fixedly connected to the inside of the adjustment groove.

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

[0013] In this invention, the operator inserts the thread cutter body into the interior of the rotating column and rotates the top of the rotating column. As the rotating column rotates, it drives the push block and the insertion rod to move, and the push block contacts the arc block, causing the arc block to push the insertion rod into the interior of the slot, thus fixing the thread cutter body. At the same time, the operator can adjust the extension length of the thread cutter body according to the different positions of the slots to achieve the functions of disassembly and adjustment.

[0019] 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.

[0020] Reference Figures 1-4As shown, this utility model provides a technical solution: a multi-functional threading cutter with a tool holder, including a tool holder body 1. The tool holder body 1 has an inner groove 2 inside, and a rotating column 3 is rotatably connected inside the inner groove 2. The threading cutter body 4 is set inside the rotating column 3. Adjustment grooves 5 are opened on both sides of the rotating column 3. Push blocks 6 are slidably connected inside the adjustment grooves 5. Insert rods 7 are fixedly connected to the side of the push blocks 6 near the adjustment grooves 5. Arc blocks 8 are fixedly connected to both sides of the inner groove 2. Several slots 9 are opened on both sides of the threading cutter body 4. The operator inserts the threading cutter body 4 into the interior of the rotating column 3 and rotates the top of the rotating column 3. While rotating, the rotating column 3 drives the push blocks 6 and the insert rods 7 to move, and the push blocks 6 contact the arc blocks 8. The arc blocks 8 push the insert rods 7 into the interior of the slots 9, thus fixing the threading cutter body 4. At the same time, the operator can adjust the extension length of the threading cutter body 4 according to the different positions of the slots 9 to achieve the functions of disassembly and adjustment.

[0021] Reference Figure 3 As shown in this embodiment: the inner wall of the inner groove 2 is provided with two annular grooves 10, and two annular blocks 11 are fixedly connected to the outer diameter surface of the rotating column 3. The surface of the annular blocks 11 is slidably connected to the inside of the annular grooves 10. When the operator moves the rotating column 3, the rotating column 3 drives the annular blocks 11 to slide inside the annular grooves 10. Through the above settings, the movement of the rotating column 3 is more stable, avoiding operation errors caused by shaking. In addition, the sliding connection design between the annular grooves 10 and the annular blocks 11 also ensures the smoothness of the rotating column 3 during movement, reduces frictional resistance, and improves the overall work efficiency.

[0022] Reference Figure 2 and Figure 4 As shown in this embodiment: the size of the insertion rod 7 is adapted to the size of the slot 9, and the surface of the insertion rod 7 is inserted into the interior of the slot 9. By adapting the size of the insertion rod 7 to the size of the slot 9, the insertion rod 7 can be stably inserted into the interior of the slot 9, thereby fixing the position of the push block 6 inside the adjustment groove 5, effectively preventing the push block 6 from shaking or falling off during use, and improving the stability and reliability of the overall structure.

[0023] Reference Figure 3 As shown in this embodiment, a buffer pad 12 is installed at the bottom of the inside of the tool holder body 1. By installing the buffer pad 12 at the bottom of the inside of the tool holder body 1, the vibration and impact of the thread cutting tool body 4 during the machining process can be reduced to a certain extent, thereby improving the service life and machining accuracy of the thread cutting tool body 4.

[0024] Reference Figure 3As shown in this embodiment: A return spring 13 is fixedly connected to the bottom of the inner groove 2. The top of the return spring 13 is fixedly connected to the bottom of the ring block 11. When the operator rotates the rotating column 3, the rotating column 3 simultaneously drives the ring block 11 to rotate, and twists the return spring 13 to store force, and drives the contact between the push block 6 and the arc block 8 to be canceled. Under the action of the rebound force of the stored spring 15, the push block 6 is quickly pushed to drive the insertion rod 7 to release the limit between it and the slot 9. When the operator releases the rotating column 3, under the action of the rebound force of the return spring 13, the ring block 11 and the return spring 13 work together to make the push block 6 quickly return to the initial position, and make the push block 6 and the arc block 8 release again, so that the insertion rod 7 can be inserted into the slot 9 for fixation.

[0025] Reference Figure 4 As shown in this embodiment: sliding grooves 16 are provided at both ends of the adjustment groove 5, and sliding blocks 14 are fixedly connected to both ends of the push block 6. The surface of the sliding block 14 is slidably connected to the inside of the sliding groove 16. When the operator moves the push block 6, the push block 6 drives the sliding block 14 to slide inside the sliding groove 16. Through the above settings, the movement of the push block 6 is more stable, avoiding the shaking or displacement that may occur during the movement of the push block 6, and improving the stability and reliability of the overall structure.

[0026] Reference Figure 4 As shown in this embodiment: a storage spring 15 is fixedly connected to the side of the push block 6 near the insertion rod 7, and the side of the storage spring 15 away from the push block 6 is fixedly connected to the inside of the adjustment groove 5. When the operator pushes the push block 6 to push the insertion rod 7, the push block 6 compresses the storage spring 15 to store force, and at the same time the insertion rod 7 is inserted into the inside of the slot 9 to fix the thread cutter body 4. When the operator releases the restriction of the push block 6, under the action of the rebound force of the storage spring 15, the push block 6 quickly drives the insertion rod 7 out of the inside of the slot 9 and returns to the initial position, waiting for the next operation.

[0027] Working principle: The operator inserts the thread cutter body 4 into the rotating column 3 and rotates the top of the rotating column 3. Simultaneously, the rotating column 3 moves the push block 6 and the insertion rod 7, causing the push block 6 to contact the arc block 8. The arc block 8 then pushes the insertion rod 7 into the slot 9, fixing the thread cutter body 4 in place. The operator can adjust the extension length of the thread cutter body 4 according to the different positions of the slot 9, achieving disassembly and adjustment. When the operator moves the rotating column 3, the rotating column 3 causes the ring block 11 to slide within the ring groove 10. This design makes the movement of the rotating column 3 more stable, avoiding wobbling. In addition to reducing operational errors, the sliding connection design between the annular groove 10 and the annular block 11 ensures the smooth movement of the rotating column 3, reduces frictional resistance, and improves overall work efficiency. The matching size of the insert rod 7 with the slot 9 allows the insert rod 7 to be stably inserted into the slot 9, thereby fixing the position of the push block 6 inside the adjusting groove 5. This effectively prevents the push block 6 from shaking or falling off during use, improving the stability and reliability of the overall structure. The buffer pad 12 installed at the bottom of the tool holder body 1 reduces vibration of the thread cutting tool body 4 during machining to a certain extent. The impact improves the service life and machining accuracy of the thread cutting tool body 4. When the operator rotates the rotating column 3, the rotating column 3 simultaneously drives the ring block 11 to rotate, and twists the return spring 13 to store force, causing the contact between the push block 6 and the arc block 8 to be released. Under the action of the spring 15, the push block 6 is quickly pushed to release the insertion rod 7 from the slot 9. When the operator releases the rotating column 3, under the action of the spring 13, the ring block 11 and the return spring 13 work together to make the push block 6 quickly return to the initial position and release the push block 6 from the arc block 8 again, allowing the insertion rod 7 to be inserted into the slot 9 for fixation. When the push block 6 moves, the push block 6 drives the sliding block 14 to slide inside the sliding groove 16. Through the above settings, the movement of the push block 6 is more stable, avoiding the shaking or deviation that may occur during the movement, and improving the stability and reliability of the overall structure. When the operator pushes the push block 6 to push the insertion rod 7, the push block 6 compresses the energy storage spring 15 to store energy. At the same time, the insertion rod 7 is inserted into the slot 9 to fix the thread cutter body 4. When the operator releases the restriction of the push block 6, under the action of the rebound force of the energy storage spring 15, the push block 6 quickly drives the insertion rod 7 out of the slot 9 and returns to the initial position, waiting for the next operation.
