Therefore, there is a need for improvement. Utility Model Content

[0004] This utility model provides a gear disc structure for a hard threading machine that allows for quick disassembly and assembly of cutting tools, rapid adjustment of tool models according to needs, longer tool life, and better working stability, thus meeting higher production demands. It solves the technical problems existing in the current threading machine technology, such as the single structure, low tool replacement efficiency, easy damage to rigid contact of cutting tools, poor adaptability of the threading machine gear disc, and poor heat dissipation, which cannot meet higher production and usage requirements.

[0005] The above-mentioned technical problem of this utility model is solved by the following technical solution: a toothed disc structure for a hard threading machine, including a base, a toothed disc shell fixed on the base, a rotating ring rotatably disposed inside the toothed disc shell, a detachable inner disc disposed on the rotating ring, a detachable tool module disposed on the inner disc, an elastic compensation structure disposed between the tool module and the inner disc, and a cooling structure disposed inside the base. In this utility model, both the inner disc and the rotating ring of the toothed disc structure are made of ductile iron, ensuring that the required toughness, strength, rigidity, wear resistance, and impact resistance are met without increasing costs. In this utility model, both the inner disc and the tool module of the toothed disc structure are detachable, facilitating adjustment of the model according to the workpiece being processed. The elastic compensation structure in this utility model can compensate for the radial and axial directions of the tool, absorbing vibration and improving service life. The cooling structure inside the toothed disc shell in this utility model can continuously circulate and cool during operation.

[0006] Preferably, the rotating ring surface is provided with a plurality of first dovetail grooves spaced apart, and the inner plate is integrally formed with a plurality of wedge-shaped protrusions that fit into the first dovetail grooves. The inner plate in this invention can be quickly installed or quickly removed, facilitating adjustment of the inner diameter according to the size of the workpiece being processed.

[0007] Preferably, the rotating ring has first pressure plates on both its front and rear sides for limiting the inner disc. The first pressure plates can limit the inner disc and enable quick disassembly and assembly.

[0008] Preferably, the inner disk surface has a second dovetail groove, and the tool module is embedded in the second dovetail groove. In this utility model, the tool module of the gear disk structure can be disassembled, which facilitates the adjustment of the model according to the workpiece being processed.

[0009] Preferably, the inner plate has a second pressure plate on its front side for limiting the position of the tool module. The second pressure plate can limit the position of the tool module and also enables quick disassembly and assembly.

[0010] Preferably, the inner side of the second pressure plate is integrally formed with a wedge-shaped pressure block embedded in the second dovetail groove. The wedge-shaped pressure block is embedded in the second dovetail groove and presses against the surface of the tool module to ensure the stability of the tool module.

[0011] Preferably, the second pressure plate is bolted to the first pressure plate and the inner disc and rotating ring. The first pressure plate and the second pressure plate are fixed together by bolts, enabling quick disassembly and assembly.

[0012] Preferably, the elastic compensation structure includes a disc spring installed between the tool module and the second dovetail groove. The disc spring can compensate for radial vibrations in the tool module.

[0013] Preferably, the elastic compensation structure further includes a silicone damping ring fitted onto the tail end of the tool module. The silicone damping ring can compensate for axial vibrations in the tool module, absorbing axial vibrations and improving the tool's service life and stability.

[0014] Preferably, the cooling structure includes spirally distributed cooling pipes inside the gear disc housing, and a quick connector for connecting to the ends of the cooling pipes is provided in the base. In this invention, the cooling pipes inside the gear disc housing can continuously circulate and cool during operation.

[0015] Therefore, the gear disc structure of the hard threading machine of this utility model has the following advantages: the cutting tools can be quickly disassembled and installed, the cutting tool model can be quickly adjusted according to needs, the cutting tool service life is longer, the working stability is better, and it can continuously cool down during the processing, which can meet higher production requirements.
