Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of cutting tools, and particularly to rotary metal cutting tools. Background Art

[0002] Cutting tools are tools used for cutting in mechanical manufacturing. The vast majority of cutting tools are mechanical. The tools used in mechanical manufacturing are basically used to cut metal materials. There are many types of cutting tools, including turning tools, hole machining tools, milling cutters, broaches, gear tools, etc. Among them, hole machining tools need to rotate the tool for drilling operations, and they are tools for machining holes from solid materials. Commonly used ones include twist drills, center drills, and deep hole drills, etc. In the actual use process, the metal is drilled by the rapid rotation of the cutting tool. When the tool is used for a long time, the outer tooth edge will be worn. Generally, the tool needs to be replaced. When replacing and installing, the tool is usually stuck in the tool holder. The tool will generate impact force during the rotation operation, and the impact force will affect the tool holder, easily causing the tool to shake, and further reducing the stability of the tool when assembled with the tool holder. Therefore, a new type of rotary metal cutting tool is proposed to solve the problems pointed out in the above background art. Summary of the Utility Model

[0003] In view of the above problems, the embodiments of the present application provide a rotary metal cutting tool to solve the problems proposed in the above background art.

[0004] The embodiments of the present application provide a rotary metal cutting tool, including a tool shank, one end of the tool shank is fixedly connected with a tool head, and a plurality of limiting grooves are evenly distributed on the side wall of the tool head. A reserved groove is arranged on one side of each limiting groove, and a fixing ring is installed in each limiting groove.

[0005] In some embodiments, the fixing ring includes a rubber pad, metal sheets are fixedly connected to the side wall of the rubber pad close to the reserved groove, and a connecting hole is opened in the center of the rubber pad.

[0006] In some embodiments, the side wall of the rubber pad is inclined, the diameter of the rubber pad close to the metal sheet is larger than that of the other side, and the sum of the thicknesses of the rubber pad and the metal sheet is smaller than the height of the limiting groove.

[0007] In some embodiments, mounting holes are opened on the side wall of each limiting groove, the mounting holes communicate with the adjacent reserved grooves, a positioning bolt is inserted into the center of the fixing ring, and the positioning bolt is threadedly connected with the mounting hole.

[0008] In some embodiments, the limiting grooves are arranged in a circular array, and there are eight limiting grooves provided on the tool head.

[0009] Through the above solution, by setting the limited position groove, during installation, the tool body can be inserted into the reserved groove. At this time, the limited position groove will be stuck on the outside of the tool body, and at the same time, the rubber pad will be in contact with the top of the tool body. The limited position groove can improve the fastening of the tool body inside the reserved groove and prevent shaking. The rubber pad plays a role in buffering the tool body, thereby ensuring the stability of the tool body during use. By setting the fixing ring, when the tool body is placed inside the reserved groove, the positioning bolt can be passed through the connection hole and installed into the installation hole. Rotating the positioning bolt, the positioning bolt will be fixed inside the installation hole. At this time, the positioning bolt will lock the tool body inside the fixing ring. The fixing ring can further reinforce the tool body and prevent loosening during cutting operations, thereby improving the safety during use.
