Description

Technical Field

[0001] The utility model relates to the technical field of parts processing, in particular to a cutting tool. Background Art

[0002] A cutting tool is a tool used for cutting in mechanical manufacturing, also known as a cutting tool.

[0003] During the parts processing, deep groove processing is required for the sealing groove. Due to the lack of standard tools and the inability of hand-grinded tools to meet the size standards, the parts processing is difficult, the dimensional accuracy does not meet the requirements, the processing size of the parts is unstable, and the tool vibration is serious.

[0004] To this end, the prior art often uses a clamp to clamp an extension rod, and clamps a conventional tool on the extension rod for processing. However, since the sealing groove is close to the side wall of the part and the part itself is relatively high, the operating length of the entire device is too long, and the tool vibration problem is prone to occur during the processing process, the operation stability is poor, and it is unsafe. At the same time, it will also cause serious tool marks on the parts, low processing efficiency, and cannot meet the cutting accuracy requirements. Utility Model Content

[0005] The purpose of the utility model is to provide a tool which can penetrate deeply into the processing part, improves the cutting accuracy and is more stable and safe.

[0006] To achieve this purpose, the present invention adopts the following technical solutions:

[0007] A cutting tool comprising:

[0008] a clamping rod configured to be connected to the clamp;

[0009] an extension rod connected to one end of the clamping rod;

[0010] The cutter head is arranged at one end of the extension rod away from the clamping rod. The clamping rod, the extension rod and the cutter head are all coaxially arranged. Along the extension direction of the clamping rod, the diameters of the clamping rod, the extension rod and the cutter head decrease successively.

[0011] Optionally, an annular flange is provided at the connection between the clamping rod and the extension rod.

[0012] Optionally, the diameter of the cutter head gradually increases in a direction away from the extension rod.

[0013] Optionally, one end of the extension rod close to the cutter head is protruding toward the cutter head.

[0014] Optionally, the other end of the clamping rod and the end of the cutter head facing away from the extension rod are parallel to each other.

[0015] Optionally, the clamping rod, the extension rod and the cutter head are integrally formed.

[0017] Optionally, the end of the cutting head facing away from the extension rod is provided with a rounded corner.

[0018] Optionally, the cutter head is dovetail-shaped.

[0019] Optionally, the knife is made of stainless steel.

[0020] Beneficial effects:

[0021] The utility model provides a cutting tool comprising a clamping rod, an extension rod, and a cutter head. The clamping rod is used to connect to a clamp so that the cutting tool can be stably connected to the clamp, ensuring stability and safety during the processing process. The extension rod is connected to one end of the clamping rod, allowing the cutting tool to penetrate into the processing area, such as when processing a sealing groove that is close to the side wall of a part and has a higher height. The cutter head is arranged at the end of the extension rod facing away from the clamping rod and is used to cut the part. The clamping rod, the extension rod, and the cutter head are all coaxially arranged, ensuring the stability and cutting accuracy of the cutting tool during the processing process and reducing processing errors caused by eccentricity or bending. Along the extension direction of the clamping rod, the diameters of the clamping rod, the extension rod, and the cutter head decrease in sequence, which can improve cutting accuracy, reduce cutting force, and make processing smoother. Because the clamping rod has a relatively large diameter, it can provide better mechanical strength and clamping force, reducing vibration and deviation during processing. Through the above arrangement, the cutting tool of the present application can penetrate into the processing area, improve cutting accuracy, and be more stable and safe.

[0031] like Figure 1-Figure 3 As shown, this embodiment provides a tool, which includes a clamping rod 1, an extension rod 2, and a cutter head 3. The clamping rod 1 is configured to be connected to a clamp, the extension rod 2 is connected to one end of the clamping rod 1, and the cutter head 3 is disposed at the end of the extension rod 2 facing away from the clamping rod 1. The clamping rod 1, the extension rod 2, and the cutter head 3 are all coaxially arranged, and the diameters of the clamping rod 1, the extension rod 2, and the cutter head 3 decrease in sequence along the extension direction of the clamping rod 1.

[0032] In this embodiment, the clamping rod 1 is used to connect to the clamp so that the tool can be stably connected to the clamp, ensuring stability and safety during the processing. The extension rod 2 is connected to one end of the clamping rod 1 so that the tool can penetrate into the processing area, such as for processing a sealing groove that is close to the side wall of the part and has a higher height. The cutter head 3 is arranged at the end of the extension rod 2 away from the clamping rod 1 and is used to perform cutting operations on the part. The clamping rod 1, the extension rod 2 and the cutter head 3 are all coaxially arranged, ensuring the stability and cutting accuracy of the tool during the processing and reducing processing errors caused by eccentricity or bending. Along the extension direction of the clamping rod 1, the diameters of the clamping rod 1, the extension rod 2 and the cutter head 3 decrease in sequence, which can improve cutting accuracy and reduce cutting force, making processing smoother. Since the clamping rod 1 has a larger diameter, it can provide better mechanical strength and clamping force, reducing vibration and offset during processing. Through the above arrangement, the tool of this embodiment can penetrate into the processing area, improve cutting accuracy, and be more stable and safe.

[0033] It should be noted that, in this embodiment, the clamper belongs to the prior art, and those skilled in the art are familiar with its specific structure and working principle, so it will not be described in detail.

[0034] Specifically, if Figure 1-Figure 3 As shown, an annular flange 11 is provided at the connection between the clamping rod 1 and the extension rod 2, which can significantly improve the performance and stability of the tool.

[0035] Specifically, if Figure 1 and Figure 2 As shown, the diameter of the cutter head 3 gradually increases in the direction away from the extension rod 2, allowing the cutter head 3 to gradually expand its cutting range during the cutting process, adapting to the processing requirements of sealing grooves of different widths. Moreover, as the diameter of the cutter head 3 gradually increases, the cutting force is correspondingly distributed over a larger area. This helps to reduce stress concentration during the cutting process, reduce tool wear, and improve cutting stability.

[0036] Specifically, if Figure 1 and Figure 2 As shown, the end of the extension rod 2 close to the cutter head 3 is protruded toward the cutter head 3, so that the cutter head 3 enters the processing part (such as the sealing groove, etc.) at a more suitable angle, optimizes the cutting angle, reduces the cutting resistance, and improves the cutting efficiency.

[0037] Specifically, if Figure 1 and Figure 2As shown, the other end of the clamping rod 1 and the end of the cutter head 3 facing away from the extension rod 2 are parallel to each other, making it more convenient and quick to install the tool on the clamp. At the same time, the parallel structure can maintain the overall balance of the tool and reduce the deviation or distortion caused by vibration or external force, thereby ensuring the stability of the cutting process and helping to enhance the stability of the tool during the processing.

[0038] Specifically, the clamping rod 1, the extension rod 2 and the cutter head 3 are integrally formed to form a strong and stable overall structure, thereby improving the performance and service life of the cutter.

[0039] Specifically, if Figure 1 and Figure 2 As shown, both ends of the clamping rod 1 are provided with chamfers, which can disperse the stress at both ends of the clamping rod 1 and reduce the possibility of stress concentration. At the same time, it can facilitate the installation of the clamping rod 1 and the clamp, and has an overall aesthetic appearance.

[0040] Specifically, if Figure 1 and Figure 2 As shown, the end of the cutter head 3 facing away from the extension rod 2 is rounded, which reduces impact and friction on the material during cutting. This helps reduce cutting forces, improve cutting efficiency, and reduce vibration and noise caused by cutting. It also reduces burrs and sharp corners during cutting, improving part quality.

[0041] Specifically, if Figure 1 and Figure 2 As shown, the cutter head 3 is dovetail-shaped, which can better adapt to complex cutting requirements, remain stable during the processing, and reduce processing errors caused by vibration or offset.

[0042] Specifically, the tool is made of stainless steel, which can ensure the tool's high strength, corrosion resistance, aesthetics and durability, meet processing requirements and improve production efficiency.

[0043] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
