Description

Technical Field

[0001] The utility model relates to the technical field of tool shafts, in particular to a tool shaft structure for preventing material accumulation and jamming. Background Technique

[0002] In the machining industry, machine tools are the most common and important processing equipment. It drives alloy tools to perform cutting on metal parts through a rotating tool shaft. After retrieval, a patent with the Chinese patent publication number CN216939743U discloses a cooling type machine tool tool shaft. Although the device cools the tool shaft by setting a cooling sleeve during use, the device cannot prevent material accumulation and jamming during use, which easily causes damage to the cutting blade and the workpiece during processing and increases production costs. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a tool shaft structure for preventing material accumulation and jamming, and solves the problems raised in the background technique.

[0004] The solution of the utility model to the above technical problems is as follows:

[0005] A tool shaft structure for preventing material accumulation and jamming includes a shaft body, and a fixed shaft is provided at the top of the shaft body;

[0006] A diversion groove is opened in the lower part of the shaft body, a cutting blade is provided on the surface of the shaft body at the diversion groove, and a receiving box is installed on the upper part of the shaft body;

[0007] A liquid storage cavity and a gas storage cavity are opened inside the receiving box, and a liquid spray head and a gas spray head are respectively installed in the liquid storage cavity and the gas storage cavity.

[0008] Based on the above technical solutions, the utility model can be further improved as follows.

[0009] Further, the liquid storage cavity and the gas storage cavity are separated by a partition board, and the liquid spray head penetrates through the gas storage cavity and is communicated with the liquid storage cavity.

[0010] The beneficial effect of adopting the above further scheme is:

[0011] The partition board clearly separates the liquid storage cavity and the gas storage cavity, avoiding the mixing and mutual interference of the liquid and the gas during the storage process. This design makes the storage and management of the two media more orderly and efficient. Through separation, the liquid and the gas can be stored in different chambers respectively, each undertaking different functions of cleaning and maintaining the tool shaft. This functional partition design improves the modularization degree of the entire tool shaft structure and is convenient for maintenance and replacement.

[0012] Further, the gas spray head and the liquid spray head are cross-distributed.

[0013] The beneficial effects of adopting the above further solution are as follows:

[0014] The cross - distribution of the gas nozzle and the liquid nozzle ensures that the cleaning medium can cover multiple areas on the surface of the tool shaft, including the blade, the flow - guiding groove, and other key parts of the tool shaft. This comprehensive cleaning method helps to remove material residues and impurities, reducing the risk of material jamming. Through the cross - distribution, the gas and the liquid can act on the surface of the tool shaft alternately or simultaneously, forming a complementary cleaning effect. The gas ejected from the gas nozzle can dry the moisture left by the liquid nozzle, preventing corrosion or secondary pollution caused by moisture residue; while the cleaning liquid ejected from the liquid nozzle can deeply clean the inaccessible gaps and dead corners. Moreover, during the cleaning process, the gas and the liquid not only act as cleaning media but also play an important role in heat dissipation. The high - speed airflow ejected by the gas can effectively carry away the heat on the surface and in the vicinity of the tool shaft, reducing the temperature rise caused by friction and cutting operations. At the same time, the cleaning liquid ejected by the liquid nozzle will also absorb and carry away a large amount of heat during the evaporation process, further enhancing the heat - dissipation effect. This dual heat - dissipation mechanism helps to keep the tool shaft operating within an appropriate working temperature range, preventing performance degradation or damage caused by overheating.

[0015] Furthermore, a bearing is installed inside the accommodating box, and the accommodating box is installed on the outside of the shaft body through the bearing.

[0016] The beneficial effects of adopting the above further solution are as follows:

[0017] As a connecting component between the accommodating box and the shaft body, the bearing mainly serves to reduce the direct contact between the two, thereby reducing friction and wear during rotation. This design helps to extend the service life of the tool - shaft structure and reduce damage and failures caused by friction.

[0018] Furthermore, liquid inlet joints and gas inlet joints are respectively installed on the accommodating box corresponding to the liquid storage cavity and the gas storage cavity, and the included angle between the liquid inlet joint and the gas inlet joint is ninety degrees.

[0019] The beneficial effects of adopting the above further solution are as follows:

[0020] Installing the liquid inlet joint and the gas inlet joint respectively at the positions on the accommodating box corresponding to the liquid storage cavity and the gas storage cavity, and the included angle between them being ninety degrees, this design makes the whole structure more compact, which is conducive to saving space. In a limited space, this layout can maximize the functions of each component, improving the integration and efficiency of the overall structure. The ninety - degree included - angle design helps to reduce the interference between the liquid inlet joint and the gas inlet joint, ensuring that they do not affect each other during their respective working processes, thus improving the stability and reliability of the system.

[0021] Furthermore, the diversion groove is a double-threaded groove that connects end to end.

[0022] The beneficial effects of adopting the above further scheme are as follows:

[0023] The double-threaded groove is designed to connect end to end, ensuring that the fluid will not be interrupted due to the disconnection of the groove during the flow process, thereby improving the continuity of fluid flow. Due to the complex geometric shape of the double-threaded groove, the fluid will have a certain scouring effect on the groove wall during the flow process. This scouring effect helps to prevent the accumulation of sediments in the groove and also helps to improve the wear resistance of the groove wall.

[0024] The utility model provides a cutter shaft structure for preventing material accumulation and jamming. It has the following

[0025] beneficial effects:

[0026] The diversion groove at the lower part of the shaft body is designed as a double-threaded groove that connects end to end. This structure can effectively guide the material to flow along the thread trajectory when the cutter shaft rotates, reduce the accumulation of material near the cutter shaft, and thus reduce the risk of jamming. The blade is located at the diversion groove. As the cutter shaft rotates, while the blade cuts the material, it also helps to push the material to flow along the diversion groove, further enhancing the anti-accumulation effect.

[0027] The inside of the accommodation box is provided with a liquid storage cavity and a gas storage cavity, and a liquid spray head and a gas spray head are respectively installed. These spray heads can spray liquid or gas when needed to clean the blade and the surrounding area, prevent material residue and adhesion, and maintain the cleanliness and sharpness of the cutter shaft. The liquid inlet joint and the gas inlet joint are respectively connected to the external liquid and gas source, facilitating the user to add or replace the cleaning medium according to needs at any time. This design makes the maintenance and operation more flexible and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1 to 4 as shown, the embodiments provided by the present invention:

[0038] Embodiment 1

[0039] A knife shaft structure for preventing material accumulation and jamming includes a shaft body 5. A fixed shaft 4 is provided at the top of the shaft body 5. A flow guiding groove 1 is formed in the lower part of the shaft body 5. The flow guiding groove 1 is a double-threaded groove that is connected end to end. The design of the double-threaded groove being connected end to end ensures that the fluid will not be interrupted due to the disconnection of the groove during the flow process, thereby improving the continuity of fluid flow. Due to the complex geometric shape of the double-threaded groove, the fluid will have a certain scouring effect on the groove wall during the flow process. This scouring effect helps to prevent the accumulation of sediments in the groove and also helps to improve the wear resistance of the groove wall. Blades 9 are provided on the surface of the shaft body 5 at the position of the flow guiding groove 1. An accommodating box 6 is installed on the upper part of the shaft body 5. A bearing 10 is installed inside the accommodating box 6. The accommodating box 6 is installed on the outside of the shaft body 5 through the bearing 10. As a connecting component between the accommodating box 6 and the shaft body 5, the bearing 10 mainly functions to reduce the direct contact between the two, thereby reducing friction and wear during rotation. This design helps to extend the service life of the knife shaft structure and reduce damage and failures caused by friction.

[0040] Embodiment 2

[0041] As Figures 1 to 4As shown in the figure, a cutter shaft structure for preventing material accumulation and jamming proposed by the present utility model, compared with the first embodiment, this embodiment further includes: a liquid storage cavity 11 and a gas storage cavity 12 are provided inside the accommodation box 6, and a liquid inlet joint 3 and a gas inlet joint 7 are respectively installed on the accommodation box 6 corresponding to the liquid storage cavity 11 and the gas storage cavity 12, and the included angle between the liquid inlet joint 3 and the gas inlet joint 7 is ninety degrees. Installing the liquid inlet joint 3 and the gas inlet joint 7 respectively at the positions on the accommodation box 6 corresponding to the liquid storage cavity 11 and the gas storage cavity 12, and the included angle between the two is ninety degrees, this design makes the whole structure more compact and is conducive to saving space. In a limited space, this layout can maximize the functions of each component and improve the integration and efficiency of the overall structure. The ninety-degree included angle design helps to reduce the interference between the liquid inlet joint 3 and the gas inlet joint 7, ensuring that they will not affect each other during their respective working processes, thus improving the stability and reliability of the system. The liquid storage cavity 11 and the gas storage cavity 12 are separated by a partition 13, and the liquid spray head 8 penetrates through the gas storage cavity 12 and communicates with the liquid storage cavity 11. The partition 13 clearly separates the liquid storage cavity 11 and the gas storage cavity 12, avoiding the mixing and mutual interference of liquid and gas during storage. This design makes the storage and management of the two media more orderly and efficient. Through separation, the liquid and gas can be stored in different chambers respectively, each undertaking different functions of cleaning and maintaining the cutter shaft. This functional partition design improves the modularity of the entire cutter shaft structure, facilitating maintenance and replacement. The liquid storage cavity 11 and the gas storage cavity 12 are respectively installed with a liquid spray head 8 and a gas spray head 2, and the gas spray head 2 and the liquid spray head 8 are cross-distributed. The cross-distribution of the gas spray head 2 and the liquid spray head 8 ensures that the cleaning medium can cover multiple areas on the surface of the cutter shaft, including the blade 9, the diversion groove 1, and other key parts of the cutter shaft. This comprehensive cleaning method helps to remove material residues and impurities and reduce the risk of jamming. Through cross-distribution, gas and liquid can act on the surface of the cutter shaft alternately or simultaneously, forming a complementary cleaning effect. The gas ejected by the gas spray head 2 can dry the water left by the liquid spray head 8, preventing corrosion or secondary pollution caused by water residue; while the cleaning liquid ejected by the liquid spray head 8 can deeply clean the inaccessible gaps and dead corners. And gas and liquid not only act as cleaning media during the cleaning process, but also play an important role in heat dissipation. The high-speed airflow ejected by the gas can effectively take away the heat on the surface of the cutter shaft and the nearby area, reducing the temperature rise caused by friction and cutting operations. At the same time, the cleaning liquid ejected by the liquid spray head 8 will also absorb and take away a large amount of heat during the evaporation process, further enhancing the heat dissipation effect. This dual heat dissipation mechanism helps to keep the cutter shaft operating within an appropriate working temperature range and prevent performance degradation or damage caused by overheating.

[0042] Working principle:

[0043] The diversion groove 1 at the lower part of the shaft body 5 adopts a double-thread groove design with the head and tail connected. When the cutter shaft rotates, these thread grooves will guide and push the material forward along the track of the groove like a screw conveyor, reducing the accumulation of the material near the cutter shaft. The blade 9 located at the diversion groove 1 cuts the material as the cutter shaft rotates. During the cutting process, the blade 9 not only breaks the material but also further pushes the material to flow along the diversion groove 1 through its rotational movement, enhancing the anti-accumulation effect.

[0044] When it is necessary to clean the cutter shaft and the surrounding area, cleaning liquid and gas are respectively injected into the liquid storage cavity 11 and the gas storage cavity 12 through the liquid inlet joint 3 and the gas inlet joint 7. The liquid nozzle 8 sprays out the cleaning liquid to clean the blade 9 and the residual material around it; the gas nozzle 2 sprays out gas to help blow dry the residual moisture and impurities, keeping the cutter shaft dry and clean. The cross-distribution design of the liquid nozzle 8 and the gas nozzle 2 makes the cleaning process more comprehensive and efficient. They can cover multiple areas on the surface of the cutter shaft, reducing cleaning dead corners and ensuring that the cutter shaft always maintains a good working state.
