Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, and in particular to a precision cutting tool capable of high-speed cutting. Background Technology

[0002] High-speed cutting precision tools are key tools for CNC machine tools to perform cutting operations under high-speed conditions. They are characterized by high precision, high efficiency, and high wear resistance. High-speed cutting precision tools have high cutting speed and low cutting force, enabling fast and smooth cutting operations. They can stably cut workpiece materials with high hardness, such as stainless steel and alloy steel, effectively reducing the frequency of tool changes and improving machining efficiency. In addition, these tools also have good heat resistance and impact resistance, maintaining high hardness and strength under high-temperature cutting conditions, and are not easily deformed or worn, ensuring the stability of cutting quality.

[0003] Most existing cutting tools are integral and lack internal cooling structures. As a result, they can only be externally cooled by the cutting fluid, which limits their cooling effect. Therefore, we propose a precision cutting tool that can perform high-speed cutting. Utility Model Content

[0004] The main objective of this invention is to provide a precision cutting tool capable of high-speed cutting, which can effectively solve the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A precision cutting tool capable of high-speed cutting includes a cutting tool and an internal cooling assembly. The internal cooling assembly includes a cutting head movably mounted on one side of the cutting tool and an internal cooling cavity opened in the center of the cutting head. A drain port is also opened in the center of one side of the cutting tool, and the drain port has a downward inclined structure. A liquid inlet is also opened in the cutting tool on one side of the drain port. Multiple sets of drain holes are arranged through the bottom of one side of the internal cooling cavity. A filter screen is fixedly installed in the upper part of the liquid inlet.

[0007] Preferably, the internal cooling assembly further includes a protective frame fixedly installed on the upper end of the cutting tool outside the liquid inlet.

[0008] Preferably, the internal cooling assembly further includes slots on both the upper and lower ends of one side of the cutting tool, and blocks on both the upper and lower ends of one side of the tool head, and the blocks and slots are matched.

[0009] Preferably, the internal cooling assembly further includes threaded holes and mounting holes respectively opened on both sides of the slot and the block.

[0010] Preferably, the internal cooling assembly further includes hexagonal socket screws that are movably installed in both the threaded hole at the bottom of the cutting tool and the mounting hole.

[0011] Preferably, the cutting tool further includes a mounting port at its center.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In this utility model, during the use of the cutting tool, part of the cutting fluid flowing down from its outer end flows to the outer end of the tool head for external cooling during cutting, and part flows through the inlet and outlet to the inner cooling chamber inside the tool head for internal cooling. Thus, through the internal and external cooling structure during the cutting of the tool head, the cooling effect is improved and overheating problems are avoided.

[0014] 2. In this utility model, the cutter head is fixedly installed by the engagement of the locking block and the internal hex screw. While ensuring stability during use, the damaged cutter head can also be easily replaced. Furthermore, the internal hex screw in the mounting hole is located at the lower part of the cutting tool after installation, which also allows the internal hex screw to be sealed after the cutting tool is installed, thereby preventing the problem of it coming loose.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Example 1:

[0025] like Figure 1-5 As shown, this embodiment provides a high-speed precision cutting tool, including a cutting tool 100 and an internal cooling assembly 200. The cutting tool 100 also includes a mounting port 101 at its center. The internal cooling assembly 200 includes a cutting head 201 movably mounted on one side of the cutting tool 100, and an internal cooling cavity 202 at the center of the cutting head 201. A drain port 203 is also provided at the center of one side of the cutting tool 100, and the drain port 203 has a downward inclined structure. A liquid inlet 204 is also provided in the cutting tool 100 on the side of the drain port 203. A plurality of drain holes 205 are arranged through the bottom of one side of the internal cooling cavity 202. The upper part of the liquid inlet 204 The internal cooling assembly 200 also includes a filter screen 206, a protective frame 207 fixedly installed on the upper end of the cutting tool 100 outside the liquid inlet 204, a slot 208 opened at both the upper and lower ends of one side of the cutting tool 100, and a block 209 set at both the upper and lower ends of one side of the tool head 201, and the block 209 and the slot 208 are matched. The internal cooling assembly 200 also includes threaded holes 210 and mounting holes 211 respectively opened on both sides of the slot 208 and the block 209. The internal cooling assembly 200 also includes internal hexagon screws 212 movably installed in the threaded holes 210 and mounting holes 211 at the bottom of the cutting tool 100.

[0026] Specifically, high-speed precision cutting tools are key tools for CNC machine tools to perform cutting operations under high-speed conditions. High-speed precision cutting tools have high cutting speeds and low cutting forces, enabling fast and stable cutting operations. During use, the cutting fluid flowing from the outer end of this cutting tool 100 is partially directed to the outer end of the tool head 201 for external cooling during cutting, and partially flows through the inlet 204 and outlet 203 into the internal cooling chamber 202 within the tool head 201 for internal cooling. This internal and external cooling structure improves the cooling effect during cutting, preventing overheating. The tool head 201 is fixed in place by the engagement of the locking block 209 and the internal hexagonal screw 212. While ensuring stability during use, the damaged cutting head 201 can also be easily replaced. The structure of the internal hex screw 212 in the mounting hole 211, which is located at the lower part of the cutting tool 100 after installation, also allows the internal hex screw 212 to be sealed after the cutting tool 100 is installed, thereby preventing it from loosening. The drain hole 205 opened on one side of the bottom of the inner cooling cavity 202 is mainly used for the outflow of cutting fluid. The filter screen 206 fixedly installed in the upper part of the inlet 204 is mainly used for filtering the top of the inlet 204 to prevent the debris generated during cutting from entering the inlet 204 and clogging it. The protective frame 207 installed on the outside of the inlet 204 is mainly used to ensure that more cutting fluid enters the inlet 204.

[0027] Working principle and usage process of this utility model:

[0028] During use, the cutting fluid sprayed onto the outer end of the cutting tool 100 is partially filtered through the filter screen 206 at the top of the inlet 204 and then flows into the inner cooling chamber 202 of the tool head 201 through the downward-sloping drain 203 on one side of the bottom of the inlet 204. After cooling the inside of the tool head 201, it flows out through the drain hole 205 on one side of the bottom of the inner cooling chamber 202. The other part of the cutting fluid flowing to the outer end of the tool head 201 directly cools the outer end of the tool head 201. Thus, the simultaneous cooling of the inner and outer ends of the cutting tool 100 during use improves its cooling effect. At the same time, if the tool head 201 on the cutting tool 100 is damaged, it can be easily replaced by removing the internal hex screws 212 on both sides of the cutting tool 100.

[0029] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
