Technical Field
[0001] This utility model relates to the technical field of ceramic lathe blade substrates, specifically to a ceramic lathe blade substrate with self-lubricating function. Background Technology
[0002] Ceramic lathe inserts are cutting tools made primarily of ceramic materials such as zirconia and alumina, using indexable inserts as the main structure and processed through nanotechnology. They possess characteristics such as high hardness, high temperature resistance, and anti-magnetization. The manufacturing process includes high-pressure forming, high-temperature sintering, and precision grinding, giving ceramic lathe inserts excellent wear resistance, high-temperature resistance, and corrosion resistance. In practical use, because the tool is in prolonged contact with the workpiece, it is necessary to periodically add ceramic-specific grease to reduce friction, decrease wear, and improve machining accuracy.
[0003] During the design process of this utility model, the following problems were found in the existing technology: Since the ceramic cutting tool substrate needs to be in contact with the workpiece for a long time, it is necessary to frequently add grease to the outside of the ceramic cutting tool substrate during actual use, which is inconvenient. At the same time, the entire assembly needs to be stopped to ensure the safety of adding grease, which leads to a reduction in the efficiency of the ceramic cutting tool substrate and cannot well meet the needs of the ceramic cutting tool substrate. Utility Model Content
[0004] The purpose of this invention is to provide a ceramic cutting tool substrate with self-lubricating function, so as to solve the problem mentioned in the background art that in actual use, it is necessary to frequently add grease to the outside of the ceramic cutting tool substrate, which is inconvenient to operate and also requires the entire component to be shut down, resulting in reduced efficiency of the ceramic cutting tool substrate and failing to meet the needs of the ceramic cutting tool substrate.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a ceramic cutting tool substrate with self-lubricating function, comprising a cutting tool body, wherein a connecting bolt hole is passed through the center of the cutting tool body, the cutting tool body has a triangular cross-section structure, a connecting part is provided at one end of the cutting tool body, and cutting tool parts are provided at the other two ends of the cutting tool body, wherein a chip guide groove is embedded on one side of the cutting tool part, and a cooling water pipe and a grease pipe are respectively installed inside the cutting tool body.
[0006] The beneficial effects of this utility model are as follows: by setting a grease tube inside the ceramic turning tool to add grease to the cutting edge of the ceramic turning tool, it is convenient for the ceramic turning tool to self-lubricate during use, reducing the wear effect of the ceramic turning tool during use. At the same time, a connectable cooling water pipe is set inside the ceramic turning tool, and when the internal temperature of the ceramic turning tool is high due to use, the cooling water is circulated to cool it down, thereby improving the performance of the ceramic turning tool and better meeting the needs of ceramic turning tool use.
[0007] To fully utilize the multiple cutting heads of ceramic lathe tools: Further configuration: the mating part has an arc-shaped cross-section structure, and the two blade parts are located at opposite corners on both sides of the mating part in the tool body. The top of the side adjacent to the mating part of one of the blade parts and the top of the side between the two blade parts are both embedded with chip guide grooves, and the chip guide grooves at the top and bottom of the tool body are mutually symmetrical.
[0008] By adopting the above technical solution, chip guide grooves are provided on the sides of both the upper and lower surfaces of the ceramic turning tool, which facilitates chip guiding operations when the two cutting edges of the ceramic turning tool are in use, ensuring the normal use of the ceramic turning tool, making full use of the ceramic turning tool head, and thus improving the service life of the ceramic turning tool.
[0009] To prevent debris from accumulating in the chip guide groove: Further configuration: one side of the inner wall of the chip guide groove is provided with an arc-shaped concave surface, and the bottom inner wall of the chip guide groove is embedded with three strip-shaped chip-blocking grooves that are inclined along the movement direction of the blade part, and the inner walls of the chip-blocking grooves are all arc-shaped, and one end of the inner wall of the chip guide groove is provided with a chip-blocking arc surface.
[0010] By adopting the above technical solution, multiple sets of inclined arc-shaped chip-blocking grooves with the same direction of blade movement are set in the chip guide groove, which facilitates the discharge of chips in the chip guide groove through the chip-blocking grooves to avoid accumulation. At the same time, an arc-shaped chip-blocking arc surface is set at the other end of the chip guide groove to further prevent the accumulation of chips at the other end of the chip guide groove when there are more chips, and further facilitates the discharge of excess chips from the other end of the chip guide groove.
[0011] To achieve cooling when the internal temperature of the ceramic cutting tool is high: The cooling water pipe is further configured as follows: the cooling water pipe is a triangular structure with an opening at one end, and the three apex angles of the cooling water pipe correspond to the docking part and the cutting tool part of the cutting tool body, respectively. The opening end of the cooling water pipe corresponds to the docking part. The opening end of the cooling water pipe is provided with an inlet and an outlet, and the inlet and outlet are located on the left and right sides of the docking part, respectively.
[0012] By adopting the above technical solution and setting up a connectable cooling water pipe, when the internal temperature of the ceramic turning tool is high due to use, it is convenient to use external cooling water to enter the ceramic turning tool through the cooling water pipe for circulation and heat exchange, thereby cooling down the ceramic turning tool and preventing the ceramic turning tool from being worn more severely due to excessive temperature, thus improving the performance of the ceramic turning tool.
[0013] To achieve self-lubrication of ceramic cutting tools: The further configuration is as follows: a U-shaped grease tube is installed inside the side connecting the docking part and the two blade parts, and the two ends of the U-shaped grease tube are respectively located on one side of the blade part and the docking part, and the diameter of the grease tube is two millimeters.
[0014] By adopting the above technical solution, one end of the grease tube is set on one side of the cutting tool. With the help of an external grease adding device, it is convenient to add grease to the ceramic cutting tool regularly through the grease tube during use, thereby reducing the wear effect of the ceramic cutting tool and improving its service life.
[0015] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0018] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0019] Please see Figures 1 to 4A ceramic cutting tool substrate with self-lubricating function includes a cutting tool body 1, a connecting bolt hole 2 penetrating through the center of the cutting tool body 1, the cutting tool body 1 having a triangular cross-section structure, a connecting part 3 provided at one end of the cutting tool body 1, and cutting tool parts 4 provided at the other two ends of the cutting tool body 1, a chip guide groove 5 embedded on one side of the cutting tool part 4, and a cooling water pipe 6 and a grease pipe 7 respectively installed inside the cutting tool body 1.
[0020] In this embodiment, as Figure 1 Figure 2 and Figure 3 As shown, the docking part 3 has an arc-shaped cross-section structure, and the two blade parts 4 are located at opposite corners on both sides of the docking part 3 in the tool body 1. The top of the side adjacent to the docking part 3 of one blade part 4 and the top of the side between the two blade parts 4 are both embedded with chip guide grooves 5, and the chip guide grooves 5 at the top and bottom of the tool body 1 are symmetrical to each other.
[0021] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, one side of the inner wall of the chip guide groove 5 is set as an arc-shaped concave surface. The bottom inner wall of the chip guide groove 5 is embedded with three strip-shaped chip-blocking grooves 501 that are inclined along the movement direction of the blade part 4. The inner walls of the chip-blocking grooves 501 are all arc-shaped. One end of the inner wall of the chip guide groove 5 is provided with a chip-blocking arc surface 502.
[0022] In this embodiment, as Figure 2 and Figure 4 As shown, the cooling water pipe 6 is a triangular structure with an opening at one end, and the three apex corners of the cooling water pipe 6 correspond to the docking part 3 and the cutting tool part 4 of the cutting tool body 1, respectively. The open end of the cooling water pipe 6 corresponds to the docking part 3. The open end of the cooling water pipe 6 is provided with an inlet and an outlet, and the inlet and outlet are located on the left and right sides of the docking part 3, respectively.
[0023] In this embodiment, as Figure 2 and Figure 4 As shown, U-shaped grease tubes 7 are installed inside the side connecting the docking part 3 and the two blade parts 4, and the two ends of the U-shaped grease tubes 7 are located on one side of the blade part 4 and the docking part 3, respectively, and the diameter of the grease tubes 7 is two millimeters.
[0024] The working process of this self-lubricating ceramic cutting tool substrate is as follows: First, fix the tool body 1 to the tool holder through the bolt holes 2 and bolts, so that the mating parts 3 of the tool body 1 mate with the corresponding mating slots of the tool holder, ensuring the stability of the tool body 1 installation. Then connect the inlet and outlet of the cooling water pipe 6 to the corresponding positions, and connect the grease pipe 7 near the two sides of the docking part 3 to the grease delivery end to complete the installation of the ceramic lathe tool. Next, when the tool holder drives the cutting tool body 1 to perform cutting, the generated chips will be guided into the chip guide groove 5. When the chip guide groove 5 is combined with the chip blocking groove 501 and the chip blocking arc surface 502 in the chip guide groove 5, the chips will be discharged from the side and the other end of the chip guide groove 5, so as to avoid chip accumulation and affect the normal use of the ceramic cutting tool. Finally, the external grease is delivered to the cutting tool section 4 through the grease pipe 7, and lubricates the cutting tool section 4 of the ceramic turning tool in conjunction with the movement of the turning tool. At the same time, when the internal temperature of the ceramic turning tool is high due to prolonged use, the internal heat is exchanged through the external cooling water pipe 6, thereby cooling the ceramic turning tool and preventing the use of the ceramic turning tool from being affected by excessive internal temperature. When the cutting tool section 4 of the ceramic turning tool is damaged, the cutting operation can be performed by adjusting the angle of the turning tool holder or flipping the ceramic turning tool installation to use another cutting tool section 4, thereby increasing the service life of the ceramic turning tool.
