Description

Technical Field

[0001] This utility model relates to the field of grooving tool technology, specifically a grooving tool holder that can be quickly disassembled and replaced. Background Technology

[0002] A grooving cutter is a type of cutting tool used in milling or turning processes. The cutter itself has a groove structure of a specific shape, which is used to insert or fix it in a grooving cutter holder. Stable tool support and cutting action are achieved through clamping or positioning mechanisms. The grooving cutter holder is the carrier and support component for mounting the grooving cutter, providing precise positioning, rigid clamping, and repeatable centering to ensure that the tool is concentric with the spindle and that the clamping is reliable. High stability and machining accuracy are achieved through designed guides, positioning surfaces, and error-proof structures. When used together, the two enable quick tool changes, accurate positioning, and good vibration control, thereby improving machining efficiency and machining quality.

[0003] However, in the existing technology, the design of the positioning surface and pin is relatively simple, making it difficult to achieve self-centering and rapid reset. At the same time, the tool change path is often complicated, requiring the gradual disassembly of bolts and replacement of disassembly tools, which increases downtime and labor intensity, and affects tool change efficiency.

[0017] 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.

[0018] This utility model provides a quick-replaceable slotting tool holder, such as... Figures 1-5 As shown, the quick-replaceable grooving knife holder includes a knife handle 1. A positioning component is rotatably connected to the middle of the front surface of the knife handle 1. A pressing component is fixedly connected to the top of the front surface of the knife handle 1. A mounting groove is provided on one side of the upper surface of the knife handle 1. A grooving knife body 2 is connected inside the mounting groove. A through groove is provided on the upper surface of the grooving knife body 2. A connecting component is inserted into the through groove. The positioning component includes a turntable 3. One side of the outer surface of the turntable 3 is rotatably connected to the center of the front surface of the tool holder 1. The other side of the outer surface of the turntable 3 is fixedly connected to a first bevel gear 4. A second bevel gear 5 meshes with the outer surface of the first bevel gear 4. A first threaded rod 6 is fixedly connected inside the second bevel gear 5. A fixing component is threadedly connected to the outer surface of the first threaded rod 6. The turntable 3 can drive the first bevel gear 4 to rotate, and the second bevel gear 5 can drive the first threaded rod 6 to rotate, so that the moving block 7 can be moved to the required position, so that the locking block 9 can be connected to the locking slot 18. Thus, the grooving tool body 2 can be moved to one end via the bolt 16, thereby determining the position of the grooving tool body 2 without repeated adjustments. Moreover, no additional tools are needed during this operation, which can effectively reduce downtime and operator labor intensity, and facilitate the improvement of tool replacement efficiency.

[0019] The fixing component includes a movable block 7, the inner thread of which is connected to the outer surface of the first threaded rod 6. The bottom end of the front surface of the movable block 7 is rotatably connected to a second threaded rod 8. The outer surface of the second threaded rod 8 is threadedly connected to a locking block 9. Rotating the second threaded rod 8 can move the locking block 9 along its surface so that its back side is inserted into the slot 18, thereby limiting the position of the plug 16. This allows the slotting knife body 2 to be installed and fixed without the need for centering, which facilitates ensuring the operation speed.

[0020] A guide groove is provided at the top of the front surface of the locking block 9. A guide rod 10 is slidably connected inside the guide groove. One end of the guide rod 10 is fixedly connected to the top of the back of the moving block 7. The guide rod 10 slides inside the guide groove, which can limit and guide the locking block 9 to prevent it from rotating with the second threaded rod 8.

[0021] The pressing assembly includes a mounting bracket 11. The inner sidewall of the mounting bracket 11 is fixedly connected to the top of the front surface of the tool holder 1. A damping rod 12 is fixedly connected to the lower surface of the mounting bracket 11. A mounting plate 13 is fixedly connected to the bottom end of the damping rod 12. A shock-absorbing spring 14 is fixedly connected to the upper surface of the mounting plate 13, which is located around the damping rod 12. A shock-absorbing pad 15 is fixedly connected to the lower surface of the mounting plate 13. The shock-absorbing spring 14 can push the shock-absorbing pad 15 to limit the upper surface of the grooving tool body 2, which can further ensure the stability of the grooving tool body 2 during installation. The shock-absorbing spring 14 and the shock-absorbing pad 15 can absorb and release the vibration generated during the use of the grooving tool body 2, which can improve the service life of the grooving tool body 2.

[0022] The connecting assembly includes a plug 16, the outer surface of which is inserted into the interior of the through groove. Positioning rods 17 are fixedly connected to both sides of the outer surface of the plug 16. A slot 18 that matches the locking block 9 is opened in the middle of the outer surface of the plug 16. The positioning rods 17 ensure the accurate orientation and position of the slot 18. Then, the plug 16 is inserted into the through groove and the positioning groove 20 in sequence to initially connect the position of the slotting knife body 2.

[0023] An indicator rod 19 is fixedly connected to the top of the front surface of the movable block 7. The end of the indicator rod 19 contacts the top of the outer surface of the plug 16. The indicator rod 19 facilitates the determination of the accuracy of the moving position of the movable block 7, and facilitates the subsequent insertion of the card block 9 into the card slot 18.

[0024] The inner bottom wall of the mounting slot is provided with a positioning groove 20. The width of the positioning groove 20 is the same as that of the plug 16, and the length of the positioning groove 20 is greater than the diameter of the plug 16. The positioning groove 20 is larger than the diameter of the plug 16, which facilitates quick insertion and eliminates the need for centering.

[0025] Working steps: First, place the grooving cutter body 2 at any position inside the mounting groove, and then use the bolts 16 to insert them into the through groove and positioning groove 20 in sequence. Next, the shock-absorbing spring 14 pushes the shock-absorbing pad 15 to limit the upper surface of the grooving cutter body 2 to prevent it from moving on its own. The shock-absorbing spring 14 and the shock-absorbing pad 15 can absorb and release the vibration generated during the use of the grooving cutter body 2. Next, the turntable 3 can drive the first bevel gear 4 to rotate, and the second bevel gear 5 can drive the first threaded rod 6 to rotate, so that the moving block 7 can be moved to the required position. Finally, the threaded rotation of the second threaded rod 8 can move the locking block 9 along its surface so that its back is inserted into the locking groove 18, thereby limiting the bolts 16. Then, the first threaded rod 6 is continuously rotated to move the moving block 7 to one end, thus determining the position of the grooving cutter body 2 without repeated adjustments.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
