Description

Technical Field

[0001] The invention belongs to the technical field of high-efficiency cutting tools with both roughing and fine milling functions, and in particular relates to a high-efficiency cutting tool with both roughing and fine milling functions. Background Art

[0002] High-efficiency tools that combine roughing and finishing play an important role in the field of modern mechanical processing. They can significantly improve processing efficiency, reduce production costs, and meet the needs of high-precision processing. They are suitable for processing non-ferrous metals such as aluminum and aluminum alloys, copper and copper alloys, as well as glass fiber and metal composite materials, glass, engineering ceramics, engineering plastics, stone and wood.

[0003] At present, there are still certain problems when using high-efficiency tools that combine roughing and fine milling. For example, the heat dissipation efficiency of the tool after processing can only rely on external natural wind or fans for heat dissipation, and such heat dissipation method can only quickly reduce the external problems of the high-efficiency tool that combines roughing and fine milling, while the inside of the tool is still in a high temperature environment. If this continues for a long time, the metal material inside the tool will soften, and then the tool will break. At the same time, the tool is composed of a cutter head and a handle. When the tool rotates at high speed to cut the material, the torque generated by the contact between the cutter head and the material will be transmitted to the handle, which can easily cause the handle to break. Since the handle is integrally connected to the cutter head, a new tool needs to be replaced, which will also increase the cost of use. Subsequently, the tool is assembled on the tool seat. If there is dust on the surface of the tool, a tilt deviation will occur when the tool is installed. The existing tool installation cannot be intuitively observed by the naked eye, so the tool installed with a tilt deviation is likely to cause a decrease in machining accuracy. Summary of the invention

[0004] The purpose of the present invention is to provide an efficient tool that combines roughing and fine milling, aiming to solve the problems of existing efficient tools that combine roughing and fine milling: poor heat dissipation efficiency, increased cost of replacing broken tools with new ones, and inability to determine whether deviations occur after assembly.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high-efficiency tool with both rough and fine milling functions, comprising a cutter head, a tool handle and a tool seat, wherein the cutter head, tool handle and tool seat are detachably connected, the cutter head is composed of a cutting edge, a longitudinal chip groove, a transverse chip groove and a docking thread column, the tool handle is composed of a thread groove, a limit groove and a positioning block, the tool handle is threadedly assembled with the cutter head through the thread groove and the docking thread column, and the tool seat is sleeved and fixed on the top end of the tool handle.

[0006] As a preferred high-efficiency tool for rough and fine milling in the present invention, the docking thread column is located at the top of the cutter head, the cutting edge is located at the bottom of the cutter head, the longitudinal chip groove is located on the surface of the cutter head and is distributed longitudinally, and the transverse chip groove is located on the surface of the cutter head and is distributed transversely.

[0007] As a preferred high-efficiency tool for rough and fine milling of the present invention, the thread groove is located at the bottom end of the tool handle, the limit groove is opened on the surface of the tool handle close to the top, and the positioning block is connected to the surface of the tool handle and close to the bottom end of the limit groove.

[0008] As a preferred high-efficiency tool with both rough and fine milling functions of the present invention, the surface of the tool handle is connected with a hexagon socket bolt, and the surface of the docking threaded column is provided with a docking groove matched with the hexagon socket bolt.

[0009] As a preferred high-efficiency tool for rough and fine milling in one of the present invention, the docking thread column is fixedly connected to the tool handle through a hexagon socket bolt and a docking groove.

[0010] As a preferred high-efficiency tool for rough and fine milling of the present invention, a water groove is opened inside the tool handle, and seals are connected to the surface of the tool handle near the top and bottom of the water groove, and a sealing ring is installed in the connecting groove of the seal on the surface of the tool handle.

[0011] As a preferred high-efficiency tool with both rough and fine milling functions of the present invention, the sealing ring is made of food-grade rubber material and is provided with two sealing rings.

[0012] As a preferred high-efficiency tool with both rough and fine milling functions of the present invention, the interior of the tool handle is equipped with a reinforcing support rod, and the reinforcing support rod is made of metal and installed on the inner wall of the tool handle.

[0013] As a preferred high-efficiency tool for rough and fine milling of the present invention, a mounting block is connected to the surface of one end of the tool handle close to the tool head, a spirit level is provided at the bottom end of the mounting block, and mounting ears at both ends of the spirit level are connected with screws.

[0014] As a preferred high-efficiency tool with both rough and fine milling functions of the present invention, the top end of the tool handle is connected to a spring, the end of the spring is installed with a support plate, and the support plate is elastically telescopically connected to the tool handle through the spring.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention not only focuses on the maintenance convenience and cost-effectiveness of the tool, but also comprehensively improves the comprehensive performance of the tool through the design of an efficient heat dissipation system and an integrated level gauge. This comprehensive performance optimization enables the tool to maintain an efficient and stable working state during rough and fine milling, meeting the needs of high-precision processing:

[0017] First, the modularization of the tool is achieved by designing the cutter head and the handle as a detachable threaded connection structure (thread groove and butt thread column). This design not only facilitates the replacement of either the cutter head or the handle when it is damaged, avoiding the high cost of overall replacement, but also improves the flexibility and efficiency of maintenance. At the same time, the use of hexagon socket bolts as fasteners not only ensures the stability of the connection, but also facilitates disassembly operations.

[0018] In addition, the tool is designed with a water tank inside, allowing cooling water to be injected into the tool handle during processing. As the tool rotates at high speed, the cooling water flows along the water tank, effectively reducing the temperature of the tool during operation, reducing the degradation of material properties and wear caused by high temperature, thereby significantly improving the tool's service life and processing stability.

[0019] Finally, the integration of a level gauge on the toolholder is an innovative move that allows operators to instantly check and adjust the level of the tool when assembling it on the toolholder. This instant feedback mechanism ensures accurate alignment of the tool during processing, avoids processing errors caused by assembly tilt, and significantly improves processing accuracy and product quality.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1

[0030] See also Figure 1-6 The present invention provides the following technical solutions: a high-efficiency tool with both rough and fine milling functions, comprising a cutter head 1, a tool handle 2 and a tool seat 3, wherein the cutter head 1, the tool handle 2 and the tool seat 3 are detachably connected, the cutter head 1 is composed of a blade 101, a longitudinal chip groove 102, a transverse chip groove 103 and a docking thread column 104, the tool handle 2 is composed of a thread groove 201, a limit groove 202 and a positioning block 203, the tool handle 2 is threadedly assembled with the cutter head 1 through the thread groove 201 and the docking thread column 104, and the tool seat 3 is sleeved and fixed on the top of the tool handle 2.

[0031] In the preferred embodiment: the docking thread column 104 is located at the top of the cutter head 1, the blade 101 is located at the bottom of the cutter head 1, the longitudinal chip groove 102 is located on the surface of the cutter head 1 and is distributed longitudinally, and the transverse chip groove 103 is located on the surface of the cutter head 1 and is distributed transversely.

[0032] In the preferred embodiment: the thread groove 201 is located at the bottom end of the handle 2 , the limiting groove 202 is opened on the surface of the handle 2 close to the top, and the positioning block 203 is connected to the surface of the handle 2 and close to the bottom end of the limiting groove 202 .

[0033] In the preferred embodiment: the surface of the tool handle 2 is connected with a hexagon socket bolt 4 , and the surface of the docking threaded column 104 is provided with a docking groove 5 matched with the hexagon socket bolt 4 .

[0034] In the preferred embodiment, the docking thread column 104 is fixedly connected to the tool handle 2 via the hexagon socket bolt 4 and the docking groove 5 .

[0035] In the embodiment, firstly, this high-efficiency tool with both rough and fine milling functions relies on existing mature technology. The carefully designed longitudinal chip grooves 102 and transverse chip grooves 103 on the cutter head 1 effectively collect waste materials during the cutting process, preventing waste materials from being retained between the cutter head 1 and the material, thereby avoiding wear of the cutter head 1. Subsequently, the design of the limit groove 202 on the handle 2 adds a diamond-shaped structure to the handle 2, significantly improving the stability and firmness when assembled with the tool holder 3.

[0036] In addition, the modular design of the tool is reflected in the detachable threaded connection structure (thread groove 201 and docking thread column 104) between the cutter head 1 and the handle 2. This innovative design allows for easy replacement of either the cutter head 1 or the handle 2 when it is damaged, greatly reducing the overall replacement cost and improving the convenience and efficiency of maintenance. At the same time, the hexagon socket bolt 4 is screwed into the docking groove 5 to further ensure the stability of the connection of the docking thread column 104, which not only ensures the reliability of the connection, but also facilitates disassembly and adjustment when necessary, thereby enhancing the flexibility of use.

[0037] Embodiment 2

[0038] See also Figure 1-6 A water tank 6 is provided inside the knife handle 2, and a sealing member 7 is connected to the surface of the knife handle 2 near the top and bottom of the water tank 6, and a sealing ring 8 is installed in the connecting groove of the sealing member 7 on the surface of the knife handle 2.

[0039] In the preferred embodiment: the sealing ring 8 is made of food-grade rubber material, and the sealing ring 8 is provided with two layers.

[0040] In the preferred embodiment: the interior of the knife handle 2 is equipped with a reinforcing support rod 9 , and the reinforcing support rod 9 is made of metal and is installed on the inner wall of the knife handle 2 .

[0041] In the embodiment, first, the seal 7 is removed so that cooling water can be injected into the water tank 6, and then the seal 7 is quickly reinstalled and connected in place. At this time, the sealing ring 8 plays its key role, fitting tightly between the seal 7 and the handle 2, effectively preventing the possibility of cooling water leaking from the connection when the tool rotates at high speed. As the tool runs at high speed, the injected cooling water will flow evenly along the path of the water tank 6. This dynamic process effectively dissipates heat for the tool and significantly reduces the temperature of the tool when it is working. This not only effectively slows down the material performance degradation and wear rate caused by high temperature, but also greatly extends the service life of the tool and improves the stability and reliability of the overall processing.

[0042] In addition, the use of the reinforced support rod 9 ensures that after the water tank 6 is opened inside the handle 2, the normal strength of the handle 2 will not be weakened, thereby effectively preventing the reduction of the overall strength of the tool and ensuring the stability and durability of the tool.

[0043] Embodiment 3

[0044] See also Figure 1-6 A mounting block 10 is connected to the surface of one end of the tool handle 2 close to the tool head 1 , a level 11 is provided at the bottom end of the mounting block 10 , and screws 12 are connected to the mounting ears at both ends of the level 11 .

[0045] In the embodiment, the integration of the level 11 on the tool handle 2 is an innovative move, which allows the operator to instantly check and adjust the horizontal state of the tool when assembling the tool on the tool holder 3. This instant feedback mechanism ensures the precise alignment of the tool during the processing, avoids processing errors caused by assembly tilt, and significantly improves processing accuracy and product quality. At the same time, the screw 12 also facilitates the removal of the level 11 from the mounting block 10 to avoid damage to the level 11.

[0046] Embodiment 4

[0047] See also Figure 1-6 The top end of the knife handle 2 is connected with a spring 13 , and the end of the spring 13 is provided with a support plate 14 , and the support plate 14 is elastically and telescopically connected to the knife handle 2 through the spring 13 .

[0048] In the embodiment, according to the description of the third embodiment, during the assembly process of the knife handle 2 and the knife seat 3, the support plate 14 and the spring 13 attached thereto will first be inserted into the preset installation hole of the knife seat 3. Then, when the knife handle 2 is fully inserted into the knife seat 3 and the bottom end of the positioning block 203 on the knife handle 2 is tightly fitted with the knife seat 3, the support plate 14 will be subjected to the extrusion force from the knife seat 3, thereby driving the spring 13 to contract. At this time, the fasteners on the knife seat 3 are used to fix it, and the assembly is completed.

[0049] This design cleverly utilizes the combination of the support plate 14 and the spring 13, so that when the connection between the knife handle 2 and the knife seat 3 needs to be disassembled, the elasticity of the spring 13 can automatically push the knife handle 2 out of the position in the knife seat 3, providing convenience for the disassembly operation, while also ensuring the flexibility and movement space of the knife handle 2 during the disassembly and assembly process.

[0050] In summary, according to the description of embodiments 1 to 4, the present invention not only focuses on the maintenance convenience and cost-effectiveness of the tool, but also comprehensively improves the comprehensive performance of the tool through the design of an efficient heat dissipation system and an integrated level gauge 11. This optimization of comprehensive performance enables the tool to maintain an efficient and stable working state during rough and fine milling, meeting the requirements of high-precision processing.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
