Description

Technical Field

[0001] This utility model relates to the field of turning tool technology, and in particular to a combined high-hardness tool. Background Technology

[0002] Modular high-hardness cutting tools are cutting tools with a modular design, characterized by their ability to be broken down into quickly replaceable functional modules. These tools typically consist of a base, replaceable tool head modules, and a connecting mechanism, allowing for rapid assembly and disassembly of the tool head and body via standardized interfaces. Their core advantages are: the cutting modules, made of high-hardness materials, can be replaced individually, reducing operating costs; the modular design allows for flexible configuration of tool heads made of different materials according to machining needs; and the precision connecting mechanism ensures the overall rigidity of the assembled modules. This structure maintains the stability of a solid cutting tool while offering the economic advantages of replaceable tool heads, making it widely used in metalworking, woodworking, and composite material cutting, particularly suitable for applications requiring frequent tool changes or machining high-hardness materials. However, existing modular high-hardness cutting tools still suffer from unstable connection positions, leading to a tendency for loosening during use.

[0003] Therefore, it is essential to invent a combined high-hardness cutting tool. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a combined high-hardness cutting tool, solving the issue that existing combined high-hardness cutting tools still suffer from unstable connection positions and are prone to loosening during use. A combined high-hardness cutting tool includes a support base, a mounting groove, a cutting tool unit, a connecting shaft, a first mounting bracket, and a second mounting bracket. The mounting groove is formed inside the support base, and the cutting tool unit is fixedly mounted inside the mounting groove. The connecting shaft is fixedly mounted at the center position above the support base. The first and second mounting brackets connect the support base and the cutting tool unit.

[0005] The tool unit includes a support body, a connecting cap, a tool mounting surface, and a tool head. The connecting cap is slidably mounted on the top of the support body, which is fixedly mounted inside the mounting slot. The connecting cap engages between a first mounting bracket and a second mounting bracket, and the tool mounting surface is located below the support body. The tool head is fixedly mounted on the tool mounting surface.

[0006] The first mounting bracket includes a load-bearing body, a cap mounting groove, a shaft mounting groove, an integral mounting bolt hole, and a bracket mounting bolt hole. The cap mounting groove is located inside both sides of the load-bearing body, and the shaft mounting groove is located inside the middle of the load-bearing body. The integral mounting bolt hole and the bracket mounting bolt hole penetrate the load-bearing body.

[0007] The internal support of the tool unit is an irregular steel prism, and the support can be slidably installed inside the mounting groove inside the support base. After installation, the connecting cap is exposed above the support base, and the tool mounting surface and the tool head are exposed below the support base. The connecting cap is a steel metal part with a "T" shaped cross section.

[0008] The first mounting bracket has a slidable mounting groove for the nut inside, which can be installed between the connecting nut and the support base. The shaft mounting groove surrounds the outside of the connecting shaft and is connected to the connecting shaft as a whole through the bolts inside the integral mounting bolt holes. The internal structures of the first mounting bracket and the second mounting bracket are completely identical, and the first mounting bracket and the second mounting bracket can be connected as a whole through the bolts inside the mounting bolt holes of the brackets.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. The tool unit of this utility model is designed to directly perform cutting operations by fixing the tool head on the tool mounting surface, while the support body provides rigid support and transmits the cutting force to the mounting groove of the support base; the connecting cap, the first mounting bracket, and the second mounting bracket form a quick-assembly and disassembly structure, the T-shaped connecting cap achieves axial limiting and radial fixing through the cap mounting groove, and the irregular prism-shaped support body enhances the torsional resistance of the mounting groove, making the tool unit an integrated component that combines cutting function, force transmission hub, and modular replacement characteristics.

[0010] 2. The first mounting bracket of this utility model achieves radial positioning through the engagement of the shaft mounting groove with the connecting shaft, while the T-shaped structure of the nut mounting groove and the connecting nut restricts axial displacement. The force-bearing body, as the core of force transmission, transmits the cutting force from the tool unit to the support base. Through bolt connections via the integral mounting bolt holes and the bracket mounting bolt holes, it achieves rigid fixation to the connecting shaft and symmetrical clamping with the second mounting bracket, forming a stable modular assembly structure. Its completely symmetrical design with the second mounting bracket not only ensures bidirectional force balance but also improves component interchangeability and maintenance efficiency.
