They are categorized by the number of blades, including single-edge, three-edge, and round hole chamfering tools. Chamfering angles are categorized by 60-degree, 90-degree, and 120-degree. Chamfering tools are widely applicable, not only for chamfering common machined parts but also for chamfering and deburring precision parts. Examples include oil, gas, and electric valves used in the aviation, military, and automotive industries, engine blocks, through-holes in cylinders and spheres, and internal bores.

[0003] In the prior art, there is a chamfering tool with internal cooling disclosed in announcement number CN220837974U. The chamfering tool is provided with a central channel inside the tool rod. Without affecting the use of the tool, the cutting fluid can be continuously introduced into the tool head through the annular closed cover. While assisting the tool head to cool down, it can also flush away the cut chips. The chip removal is smooth and efficient, which is conducive to improving the chamfering accuracy. It is easy to install and use and has a long service life.

[0004] However, in the implementation of relevant technologies, it was found that the chamfering cutter with internal cooling designed above has the following problems: the existing technology can circulate cutting fluid for cooling and lubrication through the cooperation of the components of the annular sealing cover during use, but during use, the cutting fluid flows in directly, and excessive circulation of cutting fluid may cause waste. In view of this, a chamfering cutter with a self-cooling and lubrication structure is provided to overcome the above defects. Utility Model Content

A discharge port 303 is provided, and the tool rod 1 passes through the through hole 306 to the inside of the blocking block 305, and a rotating structure is formed between the blocking block 305 and the tool rod 1; first, coolant is injected into the storage shell 301, and when the tool rod 1 rotates, it drives the feed port 302 to rotate, and the blocking block 305 fixed by the bottom plate 304 fits and blocks the feed port 302. When the feed port 302 rotates to correspond to the flow hole 307, the coolant flows into and passes through the tool rod 1 and the cutter head 2, and flows out from the discharge port 303 to achieve cooling and lubrication effects. The staged injection can save coolant and avoid waste caused by direct injection. Example 2

[0023] In addition to all the technical features of the first embodiment, the present embodiment also includes: a sleeve 4 is connected to one side of the outer wall of the storage shell 301, a connecting pipe 5 is passed through the interior of the sleeve 4, one end of the connecting pipe 5 is connected to the delivery pipe 6, the storage shell 301 is threadedly connected to the sleeve 4, the sleeve 4 is threadedly connected to the connecting pipe 5, a support mechanism 7 is provided on one side of the storage shell 301, the support mechanism 7 includes an upper cover plate 701, the upper cover plate 701 is fixed above the storage shell 301 on the outer wall of the knife rod 1, and a lower cover plate 702 is fixed below the storage shell 301 on the outer wall of the knife rod 1, the support mechanism 7 also includes a sealing ring 703, the sealing ring 703 is fixed inside the upper cover plate 701, and the inner wall of the sealing ring 703 is provided with a placement hole 704, the inner wall of the upper cover plate 701 is rotatably connected with a friction roller 705, and the friction rollers 705 are equidistantly and evenly distributed about the inner wall of the upper cover plate 701, and the friction rollers 705 are tightly fitted with the storage shell 301; they are threadedly connected to the storage shell 301 through the sleeve 4, and are also threadedly connected to the connecting pipe 5, so that the chamfering cutter can be disassembled and assembled, and at the same time, coolant is transported through the delivery pipe 6 and the storage shell 301 is limited to avoid rotation with the rotation of the tool rod 1. The upper cover plate 701 and the lower cover plate 702 improve the sealing of the storage shell 301 through the sealing ring 703 and the placement hole 704, and at the same time, the smoothness of the rotation of the tool rod 1, the upper cover plate 701 and the lower cover plate 702 is improved through the friction roller 705.

[0024] Working principle: The tool bar 1 and the tool head 2 form a chamfering tool, which is threadedly connected to the connecting pipe 5 through the sleeve 4 and inserted into the storage shell 301 and threadedly connected. The coolant is introduced through the delivery pipe 6 and the coolant enters the storage shell 301. When the tool bar 1 rotates, it fits the bottom plate 304 and rotates along the blocking block 305 through the through hole 306, thereby driving the feed port 302 to rotate. When the feed port 302 corresponds to the flow hole 307, the coolant enters to form an intermittent flow to avoid waste caused by direct flow. At the same time, The sleeve 4 is threadedly connected to the storage shell 301 to prevent the storage shell 301 from being affected by the knife rod 1 and rotating along with it. The coolant eventually flows out through the discharge port 303. The upper cover plate 701 and the lower cover plate 702 cover the top and bottom ends of the storage shell 301, and the sealing is improved by the sealing ring 703. The position of the knife rod 1 is reserved through the placement hole 704. When the upper cover plate 701 and the lower cover plate 702 rotate with the knife rod 1, they slide and conflict with the conflict roller 705 through the storage shell 301, thereby maintaining the smoothness of the rotation of the knife rod 1.
