Description

Technical Field

[0001] This utility model belongs to the field of machining tool technology, specifically relating to a metal cutting tool suitable for high-speed cutting. Background Technology

[0002] Cutting tools are tools used for cutting processes in mechanical manufacturing. They are divided into metal cutting tools, woodworking tools, and mining tools, etc. Machining tools are mainly used for metal cutting, and common types include turning tools, milling cutters, drills, boring tools, and reamers.

[0003] Currently, especially in high-speed cutting machining scenarios, high heat is generated between the tool and the workpiece due to high-speed rotation friction. Under the influence of high heat for a long time, the tool will deform and be damaged. It is necessary not only to spray coolant towards the tool during machining, but also to design a metal cutting tool that is easy to disassemble, repair or replace.

[0004] A search revealed that Chinese utility model patent with authorization announcement number CN222429387U discloses "a metal cutting tool for high-speed cutting", which includes a milling cutter for cutting, a connecting sleeve for guiding, a fixing sleeve for mounting the milling cutter, a tapered clamp for fixing the milling cutter, and a cooling assembly for cooling the milling cutter. The milling cutter is vertically arranged at the center of the connecting sleeve, and the fastening sleeve is vertically threaded inside the connecting sleeve.

[0005] While existing metal cutting tools, including those mentioned above, facilitate the installation and removal of milling cutters, in actual use, the milling cutters themselves still contain a high temperature after cutting. Even with continuous injection of coolant, a certain cooling time is required, and they cannot be replaced immediately, resulting in a reduction in machining efficiency.

[0041] 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.

[0043] Furthermore, by Figure 1 and Figure 2As shown in this embodiment, mounting holes 21 are machined on the mounting plate 2 for fixing the mounting plate 2 to a fixed object. Two side fixing plates 3 are symmetrically fixed to the bottom surface of the mounting plate 2. The rotating mounting base 4 is rotatably mounted between the two side fixing plates 3. Multiple tool assemblies 1 are fixed at equal intervals along the circumferential direction to the outer wall of the rotating mounting base 4. The drive mechanism 5 is drivably connected to the rotating mounting base 4 for driving the rotating mounting base 4 to rotate. With the above scheme, in use, the mounting plate 2 is fixed to the processing equipment bracket or the output shaft of the machine tool using bolts. After the workpiece is clamped and fixed, the workpiece is cut by the tool assembly 1. If necessary, the drive mechanism 5 can be activated to drive the rotating mounting base 4 to rotate and switch to other tools. The tool assembly 1 is used in rotation, which provides sufficient cooling time for the tool assembly 1 and avoids the problem of burns caused by high temperature during replacement. On the other hand, if the tool assembly 1 is accidentally damaged, it does not need to be disassembled immediately. If the conditions for continued production are met, other tool assemblies 1 can be switched to take over the operation, ensuring production efficiency. In this utility model, multiple tool assemblies 1 are set and installed at equal intervals along the circumference on the rotating mounting base 4. The rotating mounting base 4 is driven by the drive mechanism 5 to rotate for switching. Subsequent machining operations can be performed without disassembling the six-flute end mill 14, which provides sufficient cooling time for the six-flute end mill 14. Different tools can also be fixed on the rotating mounting base 4, and different machining operations can be performed by switching tools.

[0044] Optionally, by Figure 1 and Figure 2 As shown, in this embodiment, the drive mechanism 5 includes: a rotating shaft 51, a worm gear 52, a perforated mounting lug 53, a worm 54, and a servo motor 55. The rotating shaft 51 is fixed to the end face of the rotating mounting base 4, and the rotating shaft 51 passes through the side fixing plate 3 to form a rotating structure. The worm gear 52 is fixed on the rotating shaft 51. The two perforated mounting lugs 53 are symmetrically fixed to the outer wall of the side fixing plate 3. The worm 54 is rotatably mounted between the two perforated mounting lugs 53 and meshes with the worm gear 52. The servo motor 55 is fixed to the outer wall of the perforated mounting lug 53 and is used to drive the worm 54 to rotate. With the above scheme, when in use, the servo motor 55 is started to drive the worm 54 to rotate. The worm 54 drives the worm gear 52 to rotate through the meshing action. The worm gear 52 drives the rotating mounting base 4 to rotate using the rotating shaft 51.

[0045] Optionally, by Figure 1 and Figure 3As shown in this embodiment, the tool assembly 1 includes: a tool holder 11, a fixed sleeve 13, and a six-flute end mill 14. The tool holder 11 is fixed to the outer wall of the rotating mounting base 4 by four diagonally distributed fixing rods 12. The fixed sleeve 13 is rotatably connected to the tool holder 11. The six-flute end mill 14 is fixedly connected to the fixed sleeve 13 by a drive motor 15. The drive motor 15 is fixed on the tool holder 11 and is used to drive the fixed sleeve 13 to rotate. With the above solution, in use, the fixed sleeve 13 is used to fix the six-flute end mill 14, and the drive motor 15 is used to drive the fixed sleeve 13 to rotate so that the six-flute end mill 14 rotates to perform cutting operations.

[0046] Optionally, by Figure 1 , Figure 3 and Figure 4 As shown in this embodiment, the tool assembly 1 further includes: a countersunk screw 16, a six-flute end mill 14 partially embedded in a fixed sleeve 13, an internally threaded countersunk hole 131 machined on the outer wall of the fixed sleeve 13, a positioning groove 141 machined on the outer wall of the six-flute end mill 14, and the countersunk screw 16 is installed on the fixed sleeve 13 by thread engagement, with one end of the countersunk screw 16 embedded in the positioning groove 141. With the above solution, during use, the six-flute end mill 14 is fixedly connected to the fixed sleeve 13 using the countersunk screw 16, which ensures installation stability and facilitates disassembly of the six-flute end mill 14, making it easy to replace different six-flute end mills 14 or other tools as needed, and also facilitating the disassembly and replacement of damaged six-flute end mills 14.

[0047] Preferably, by Figure 1 , Figure 3 and Figure 4 As shown in this embodiment, the countersunk screws 16 are symmetrically distributed in two groups, and there are two countersunk screws 16 in the same group at intervals, which has a high locking effect and ensures the stability of the installation of the six-flute end mill 14.

[0048] Preferably, by Figure 1 , Figure 3 and Figure 4 As shown in this embodiment, the outer wall of the six-flute end mill 14 abuts against the inner wall of the fixed sleeve 13. With the above solution, this close fit has high stability during use, further improving the stability of the six-flute end mill 14 and preventing the six-flute end mill 14 from shaking during operation.

On the other hand, the plane 132 and the plane 142 restrict the rotational freedom of the six-flute end mill 14, avoid the six-flute end mill 14 from rotating relative to the fixed sleeve 13 during operation, and ensure the stability and safety of the six-flute end mill 14.

[0050] Preferably, by Figure 1 As shown, this embodiment also includes: a cooling rack 6 and a universal bamboo tube 7. The cooling rack 6 is fixed to the outer wall of the side fixing plate 3, and the universal bamboo tube 7 is fixed on the cooling rack 6. With the above solution, in use, the universal bamboo tube 7 is connected to a water pump through a hose to draw coolant from the coolant source and spray it toward the six-flute end mill 14 through the universal bamboo tube 7 to cool the six-flute end mill 14 and ensure the working performance of the six-flute end mill 14.

[0051] It should be noted that the servo motor 55 is a commercially available standard device with a built-in power switch. Those skilled in the art can make conventional selections according to their needs. Its working principle is common knowledge known to those skilled in the art and has been fully disclosed in existing technology, so it will not be elaborated further in this article.

After the workpiece is clamped and fixed, the workpiece is cut by the tool assembly 1.

[0055] When necessary, the servo motor 55 can be started to drive the worm gear 54 to rotate. The worm gear 54 drives the worm wheel 52 to rotate through meshing. The worm wheel 52 drives the rotating mounting base 4 to rotate via the rotating shaft 51, and other tool assemblies 1 can be switched to take over the operation. On the one hand, the tool assembly 1 is given sufficient cooling time, avoiding the problem of being easily burned when changing due to high temperature. On the other hand, if the tool assembly 1 is accidentally damaged, it does not need to be disassembled immediately. If the conditions for continuing production are met, other tool assemblies 1 can be switched to take over the operation, ensuring production efficiency.

[0056] In another aspect of this utility model, the universal bamboo joint tube 7 is connected to a water pump via a hose to draw coolant from the coolant source and spray it toward the six-flute end mill 14 through the universal bamboo joint tube 7 to cool the six-flute end mill 14 and ensure the working performance of the six-flute end mill 14.

[0057] In this invention, multiple tool assemblies 1 are installed at equal intervals along the circumference on a rotating mounting base 4, and a drive mechanism 5 is used to drive the rotating mounting base 4 to rotate for switching.
