Description

Technical Field

[0001] This utility model relates to the field of alloy cutting tool technology, specifically an alloy cutting tool with replaceable cutting heads. Background Technology

[0002] Blades, as an important component of cutting tools, have edges that are carefully designed and crafted to effectively pierce, cut, or scrape the surfaces of various materials. These blades can be made from a variety of different materials, including but not limited to flint, metals (usually strong and durable steel), and ceramics. Over time and with technological advancements, the materials and manufacturing processes of blades have also continued to evolve. For example, alloy blades are a type of high-performance blade designed specifically for mechanical equipment. They are made by fusing multiple metallic elements, resulting in extremely high hardness and wear resistance, which greatly extends service life and ensures stable performance and reliability under various harsh conditions.

[0003] The existing publication CN221620870U discloses a carbide tool tip that is easy to disassemble and install, relating to the field of carbide tool technology. It includes a tool shank, with a positioning ball fixedly connected to the rear end of the shank and a carbide tool tip fixedly connected to the front end. The surface of the carbide tool tip has a cutting edge groove, and a cutting edge is slidably connected inside the cutting edge groove. A sliding groove is formed inside the carbide tool tip, and a fixing device is installed inside the sliding groove. This easy-to-disassemble and install carbide tool tip uses a key block and a keyway to fix a new carbide tool tip to the tool shank. A sealing ring seals the contact point between the carbide tool tip and the tool shank, preventing cutting fluid from entering the interior of the carbide tool tip and causing corrosion, thus extending the service life of the carbide tool tip. The carbide tool tip can be replaced individually after damage, reducing tool replacement costs.

[0004] When changing the cutting head of tools made of alloy materials currently in use, the operation usually requires consideration of the tool's specific installation position. Since these alloy tools are specially designed to match and be installed on corresponding cutting equipment, the cutting equipment must be precisely aligned with the workpiece during use. However, this alignment operation often results in the cutting head's position being obstructed by the field of vision. During the cutting head replacement process, in order to ensure the accuracy of the installation, the operator has to lower their head to adjust their field of vision so that they can clearly see the correct installation position of the cutting head. This adjustment action, which is necessary due to obstructed vision, not only increases the difficulty of changing the cutting head but also significantly reduces the convenience of the installation process, thereby affecting the overall work efficiency.

[0005] Therefore, those skilled in the art have provided a replaceable-head alloy cutting tool to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a replaceable cutting head alloy cutting tool to solve the problem mentioned in the background art that the existing alloy cutting tools suffer from obstructed view and reduced installation convenience when changing the cutting head.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A replaceable-head alloy cutting tool includes: a cutting shaft, a mating hole at the bottom of the cutting shaft, a cutting head body mounted below the mating hole, a guide cable connected to the top of the cutting head body, a lower feed cylinder fixedly mounted on the right side wall of the cutting shaft, an upper feed cylinder mounted above the lower feed cylinder, a rotating screw threadedly connected to the inside of the upper feed cylinder, a clamping screw threadedly mounted on the outer side of the top of the rotating screw, a reel fixedly connected to the middle of the rotating screw, a cutting head holder fixedly mounted on the upper end of the cutting shaft by bolts, a top seat fixedly mounted above the cutting head holder, and a connecting seat mounted above the top seat.

[0009] As a further improvement of this utility model, the cutter shaft is connected to the cutter head body by a mating hole.

[0010] As a further improvement of this utility model: the upper end of the cutter head body and the lower end of the guide cable are connected by a thread, and the lower inlet cylinder and the docking hole are interconnected.

[0011] As a further embodiment of this utility model: the guide cable is inserted into the lower feed cylinder through the docking hole, the upper end of the guide cable is connected to the spool on the rotating screw, and the rotating screw and the upper feed cylinder are connected by a thread.

[0012] As a further embodiment of this utility model: a claw rod is rotatably connected to the outer edge of the top seat, and a connecting shaft is provided between the lower end of the claw rod and the top seat, and a torsion spring is sleeved on the surface of the connecting shaft.

[0013] As a further embodiment of this utility model: the claw rod forms a rotating structure with the top seat through the connecting shaft, and the lower end of the connecting seat and the upper end of the top seat form an interlocking structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] A docking hole is designed at the bottom of the cutter shaft, corresponding to the upper end of the cutter head body. The top of the cutter head body is threadedly connected to the guide cable, ensuring a stable connection. The guide cable passes through the inner wall of one side of the docking hole, then exits from the inside of the lower feed cylinder, and is guided upwards into the upper feed cylinder. Inside the upper feed cylinder, the guide cable is tightly connected to the lower end of the rotating screw, ensuring smooth operation. A reel is connected to the middle of the rotating screw, and threaded grooves are provided on the surface of the reel. These threaded grooves greatly facilitate the winding process of the guide cable. By winding the guide cable, it is easy to pull the cutter head body connected to the lower end of the guide cable, thereby lifting the cutter head body upwards. This design allows the operator to coordinate the installation position of the cutting tool without bending over, greatly reducing the requirements for the installation angle. Using the pulling function of the guide cable to install the cutter head body makes the entire installation process simple and quick. The rotating screw is located outside the cutter shaft, allowing the operator to directly install the cutter head body through external operation, greatly improving the convenience of installation.

[0024] 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.

[0025] Please see Figures 1 to 7 This utility model provides an alloy cutting tool with a replaceable cutting head, including: a cutting shaft 1, a docking hole 14 at the bottom of the cutting shaft 1, and a cutting head body 2 installed below the docking hole 14. The cutting shaft 1 and the cutting head body 2 are connected by a snap-fit ​​connection through the docking hole 14.

[0026] Specifically, when connecting the cutter head body 2 to the docking hole 14, protrusions are designed on both sides of the surface of the docking hole 14, and slots are correspondingly opened on both sides of the surface of the cutter head body 2. The size and position of these slots match the protrusions on the docking hole 14. When the cutter head body 2 is pushed into the docking hole 14, these protrusions will align with the slots. As the cutter head body 2 moves upward, these protrusions will gradually embed into the slots, thereby achieving a mechanical positioning. This design not only ensures the stable installation of the cutter head body 2, but also greatly improves the convenience and reliability of installation. Through this structure, the cutter head body 2 can be firmly fixed in the docking hole 14, ensuring stability and durability during use.

[0027] The top of the cutter head body 2 is connected to a guide cable 11. A lower feed cylinder 12 is fixedly installed on the right side wall of the cutter shaft 1, and an upper feed cylinder 9 is installed above the lower feed cylinder 12. A rotating screw 10 is threadedly connected inside the upper feed cylinder 9. A clamping screw 15 is threadedly installed on the outer side of the top of the rotating screw 10. A reel 13 is fixedly connected to the middle of the rotating screw 10. The upper end of the cutter head body 2 is threadedly connected to the lower end of the guide cable 11. The lower feed cylinder 12 and the docking hole 14 are internally connected. The guide cable 11 is inserted into the lower feed cylinder 12 through the docking hole 14. The upper end of the guide cable 11 is connected to the reel 13 on the rotating screw 10. The rotating screw 10 and the upper feed cylinder 9 are threadedly connected.

[0028] Specifically, the guide cable 11 is installed with its lower end connected to the upper end of the cutter head body 2 via a threaded connection. This design greatly improves the convenience of connecting and disassembling the guide cable 11 and the cutter head body 2. When replacing the cutter head body 2, the guide cable 11 is separated from the old cutter head and connected to the new cutter head via a threaded connection. The guide cable 11 cleverly passes through the inner wall of the docking hole 14, then penetrates into the lower feed cylinder 12, and continues upward into the upper feed cylinder 9. To ensure the stability and reliability of the guide cable 11, its upper end is fixed to the reel 13 on the rotating screw 10. When the rotating screw 10 starts to rotate, the reel 13 rotates accordingly, and the guide cable 11 is wound and wound up by the reel 13. During the cutter head replacement process, the threaded connection structure between the rotating screw 10 and the upper feed cylinder 9 is used for operation. Since it is a fixed connection, when the rotating screw 10 rotates, the reel 13 will also rotate. The guide cable 11 gradually shortens as it is wound around the reel 13. As the guide cable 11 shortens, the replacement cutter head body 2 is pulled towards the docking hole 14 at the bottom of the cutter shaft 1. When the cutter head body 2 contacts the docking hole 14, the direction of the cutter head body 2 only needs to be adjusted to ensure that the protrusion on the docking hole 14 can be smoothly inserted into the slots on both sides of the cutter head body 2. Next, by rotating the clamping screw 15, the upper surface of the upper feed cylinder 9 is clamped to ensure the stable installation of the cutter head body 2. The lower surface of the clamping screw 15 is bonded with a rubber layer. This design increases friction and helps to position the rotating screw 10. Through this traction mechanism of the guide cable 11, the cutter head body 2 can be guided and installed from the outside. The operator does not need to look down to adjust the viewing angle to achieve precise installation, which greatly improves work efficiency and installation accuracy.

[0029] A tool holder 3 is fixedly installed on the upper end of the tool shaft 1 by bolts. A top seat 4 is fixedly installed on the top of the tool holder 3. A connecting seat 6 is installed on the top of the top seat 4. A claw rod 5 is rotatably connected to the outer edge of the top seat 4. A connecting shaft 7 is provided between the lower end of the claw rod 5 and the top seat 4. A torsion spring 8 is sleeved on the surface of the connecting shaft 7. The claw rod 5 and the top seat 4 form a rotating structure through the connecting shaft 7. The lower end of the connecting seat 6 and the upper end of the top seat 4 form an interlocking structure.

[0030] Specifically, the lower end of the connecting seat 6 is designed as a cross-shaped structure, which fits into the cross-shaped groove inside the upper end of the top seat 4. This design allows the connecting seat 6 and the top seat 4 to be installed in a fitted manner. To further facilitate the installation process of the connecting seat 6 and the top seat 4, the rotation structure of the claw bar 5 and the connecting shaft 7 is utilized. When the claw bar 5 extends outward, it facilitates the connection between the connecting seat 6 and the top seat 4. Once the installation process of the connecting seat 6 and the top seat 4 is completed, the elasticity of the torsion spring 8 will take effect, so that the claw bar 5 tightly holds the connecting seat 6, thereby ensuring that the connection between the connecting seat 6 and the tool holder 3 is stable and reliable. When disassembly or replacement is required, the operator only needs to pry open the claw bar 5 to easily separate the connecting seat 6 and the top seat 4. The whole process is simple and efficient.

[0031] The working principle of this utility model is as follows:

[0032] When replacing the cutter head body 2 using this utility model, firstly, remove the old cutter head body 2 from the docking hole 14. The disassembly process is very simple; just rotate the clamping screw 15 to separate the clamping screw 15 from the upper surface of the upper feed cylinder 9. Then, rotate the rotating screw 10 counterclockwise. Since the rotating screw 10 and the upper feed cylinder 9 are connected by a thread, the rotating screw 10 will gradually rise, and the reel 13 will also rotate with the rotation of the rotating screw 10, thereby gradually releasing the guide cable 11. At this time, the cutter head body 2 will gradually slide out of the docking hole 14 under its own weight, completing the disassembly process. Next, install the new cutter head. First, connect the new cutter head using a threaded connection, aligning the slot of the new cutter head body 2 with the protrusion on the surface of the docking hole 14. Insert the guide cable 11 through the inner wall of the docking hole 14 into the interior of the lower feed cylinder 12, and then continue to insert it upwards into the interior of the upper feed cylinder 9. At this time, rotate the rotating screw... 10. Since the rotating screw 10 and the upper feed cylinder 9 are connected by a thread, the rotating screw 10 will gradually descend, and the reel 13 will also rotate with the rotating screw 10, thereby gradually winding up the guide cable 11 until the new cutter head body 2 is firmly pulled into the docking hole 14, and the protrusion on the docking hole 14 is fully embedded in the slot. Then, the new cutter head body 2 is inserted into the docking hole 14 until the protrusion is fully embedded in the slot, achieving mechanical positioning. Finally, the clamping screw 15 is rotated to press the clamping screw 15 tightly against the upper surface of the upper feed cylinder 9, ensuring the stable installation of the new cutter head body 2. During the entire replacement process, the operator does not need to look down to adjust the viewing angle to achieve precise installation, which greatly improves work efficiency and installation accuracy. At the same time, due to the use of mechanical positioning and threaded connection, the convenient installation and disassembly of the cutter head body 2 from the outside is ensured, thereby improving the performance and life of the alloy cutter.

[0033] 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.
