[0018] In order to make the objectives, technical solutions and advantages of the present invention clearer, the double-inclined surface combined air-expansion chuck of the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] In the description of the present invention, unless otherwise specified, "a plurality of" means two or more; the terms "center", "longitudinal", "transverse", "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0020] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0021] Please refer to Figures 1 to 5 , the double-bevel combined air-expansion chuck of the embodiment of the present utility model is characterized by comprising: an outer housing 1, a shaft body 2, and a connecting seat 3. The shaft body 2 includes a first rotating shaft 21 and a second rotating shaft 22. The first rotating shaft 21 and the second rotating shaft 22 are both provided with bevel grooves 4. One end of the first rotating shaft 21 near the bevel groove 4 is connected to one end of the second rotating shaft 22 far from the bevel groove 4. The connecting seat 3 is fixedly arranged in the bevel groove 4.

[0022] In the above embodiment, the shaft body 2, as the core part of the rotating shaft, is composed of the first rotating shaft 21 and the second rotating shaft 22. The first rotating shaft 21 and the second rotating shaft 22 are both provided with bevel grooves 4. This design not only realizes the tight connection between the shaft body 2 and the connecting seat 3, but also ensures that the connecting seat 3 can maintain a stable position during rotation through the limiting function of the bevel groove 4. There are two columns of bevel grooves 4, which are respectively located on the first rotating shaft 21 and the second rotating shaft 22. This symmetrical design enables the connecting seat 3 to be more firmly connected to the outer housing 1, improving the stability of the entire rotating shaft. The split design of the first rotating shaft 21 and the second rotating shaft 22 brings the following improvements. First, the split design makes it more convenient to process the bevel groove 4. Since the two rotating shafts are separated, they can be processed separately, avoiding the tool breakage problem that may occur when processing an integral shaft body 2, and improving the processing efficiency and accuracy. Second, the split design is also convenient for subsequent maintenance and replacement. If one of the rotating shafts fails or is damaged, it can be replaced separately without replacing the entire rotating shaft, reducing the maintenance cost. In addition, the structural design of the double-bevel combined air-expansion chuck also considers the convenience and safety of operation. Through the limiting function of the bevel groove 4, the connecting seat 3 can maintain a stable position during rotation, avoiding potential risks caused by vibration or displacement. At the same time, this design also makes the rotating shaft more flexible and reliable during the clamping and releasing processes.

[0023] Please refer to Figures 1 to 5 , in another embodiment, the connecting seat 3 is provided with a first limiting groove 31, and the bevel groove 4 is provided with a limiting seat 41, and the limiting seat 41 matches the limiting groove.

[0024] In the above embodiment, the limit seat 41 is placed in the bevel groove 4, and its shape and size are completely consistent with the first limit groove 31 on the connecting seat 3. When the connecting seat 3 is installed on the bevel groove 4, the limit seat 41 will naturally embed into the limit groove to achieve a tight connection between the two. This matching not only ensures the stable position of the connecting seat 3 on the shaft body 2, but also avoids possible displacement or shaking during the rotation of the shaft. Through the matching design of the limit groove and the limit seat 41, the double-bevel combined air expansion chuck not only ensures the structural stability, but also improves the operating accuracy and reliability of the shaft.

[0025] Please refer to Figures 1 to 5 In another embodiment, the outer shell 1 is provided with a second limiting groove 11 matching the shape of the connecting seat 3 .

[0026] In the above embodiment, the outer shell 1 is the basic structure of the entire rotating shaft, and its stability and precision have a crucial impact on the performance of the entire rotating shaft. Therefore, the second limiting groove 11 is provided on the outer shell 1 to ensure that the connecting seat 3 can be accurately positioned at the predetermined position of the outer shell 1 during assembly. Secondly, the shape of the connecting seat 3 matches the second limiting groove 11, which means that the connecting seat 3 can be accurately guided and constrained by the limiting groove when inserted into the outer shell 1. This matching not only improves the assembly accuracy, but also ensures the stability of the connecting seat 3 during the operation of the rotating shaft, avoiding the performance degradation caused by looseness or displacement. Finally, this design also enhances the overall structural strength of the rotating shaft. Since the connecting seat 3 and the outer shell 1 are tightly fixed by the second limiting groove 11, the rotating shaft can better maintain its stability and reliability when subjected to various external forces.

[0027] Please refer to Figures 1 to 5 In another embodiment, a protective shell 5 is further provided at the portion where the outer shell 1 is connected to the connecting seat 3 .

[0028] In the above embodiment, the protective shell 5 serves as a protective layer between the outer shell 1 and the connecting seat 3, and can effectively resist dust, dirt, moisture and other substances in the external environment that may damage the normal operation of the shaft.

[0029] Please refer to Figures 1 to 5 In another embodiment, the first rotating shaft 21 and the second rotating shaft 22 are both provided with a plurality of through holes 6. When the first rotating shaft 21 and the second rotating shaft 22 are assembled together, the through holes 6 are connected.

[0030] In the above embodiment, the first rotating shaft 21 and the second rotating shaft 22 are precisely processed during design and manufacture to ensure that the positions of their respective through holes 6 correspond to each other. When the two rotating shafts are assembled together, their interface parts will fit tightly so that their respective through holes 6 can be aligned in the axial and radial directions. This design allows lubricating oil, gas or other media to flow freely between the rotating shafts through the through holes 6, providing the necessary lubrication and power for the normal operation of the rotating shafts. In addition, this design also ensures that the connection between the rotating shafts is stable and reliable. Due to the presence of the through holes 6, the rotating shafts will have more contact points when assembled, thereby enhancing the stability and firmness of the connection. At the same time, the connection of the through holes 6 also provides an additional channel for the torque transmission between the rotating shafts, further improving the overall performance of the rotating shafts. In summary, the setting and connection design of the through holes 6 on the first rotating shaft 21 and the second rotating shaft 22 not only meet the functional requirements of the rotating shafts, but also enhance the stability and reliability of the connection between the rotating shafts, providing a strong guarantee for the stable operation of the double-bevel combined air expansion chuck.

[0031] Please refer to Figures 1 to 5 In another embodiment, a spring 7 is provided at the axial center position of the second rotating shaft 22 .

[0032] In the above embodiment, the arrangement of the spring 7 enables the second rotating shaft 22 to produce a certain elastic deformation when subjected to external force. This elastic deformation helps to alleviate or absorb external impact and vibration, thereby protecting other components inside the rotating shaft from damage. In addition, the elasticity of the spring 7 can also buffer the rotating shaft when subjected to instantaneous overload, thereby avoiding direct damage to the rotating shaft structure.

[0033] Please refer to Figures 1 to 5 In another embodiment, the through hole 6 is a threaded hole, and the first rotating shaft 21 and the second rotating shaft 22 are threadedly connected through the threaded hole.

[0034] In the above embodiment, the through hole 6 is in the form of a threaded hole, so that the first rotating shaft 21 and the second rotating shaft 22 can be tightly fixed by threaded connection. This design principle ensures the firmness and reliability of the connection, and is easy to install and disassemble, thereby improving the convenience of using the rotating shaft.

[0035] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present utility model. However, as long as it does not depart from the content of the technical solution of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
