[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-5 The present invention provides an embodiment of a pneumatic auxiliary support device, comprising a main body 1, a first shaft 3 embedded and fixed on the upper end face of the main body 1, a second shaft 4 disposed inside the first shaft 3, a shaft locking interface 2 opened on the rear end face of the main body 1, two internal hexagon bolt holes 5 opened on the upper end face of the main body 1, the main body 1 is made of aluminum alloy, and a pneumatic cylinder mechanism is bolted to the rear end face of the main body 1 for driving the first shaft 3 to achieve locking and unlocking.

[0022] Specifically, the main body 1 is made of aluminum alloy. Aluminum alloy makes the body lightweight, facilitating installation and reducing the load on the clamping plate. A5052 aluminum alloy also has good corrosion resistance, adapting to the processing environment and preventing structural instability due to rust. This achieves a balance between lightweight design and structural stability, extending the device's service life in complex environments. During use, the upper surface of the main body 1 is fixed with a first shaft 3, which internally houses a second shaft 4. While the first and second shafts 3 are made of different materials, both are high-strength materials that stably transmit support force, effectively preventing workpiece vibration and deformation, and improving processing accuracy. The rear end of the main body 1 has a shaft locking interface 2, allowing connection between the main body 1 and the pneumatic drive mechanism. The pneumatic drive mechanism connects to the shaft through the locking interface 2, enabling locking or unlocking of the shaft. This device, through automated pneumatic operation, effectively prevents workpiece vibration and deformation during support, significantly improving operational stability and efficiency, and is suitable for processing scenarios requiring stable support.

[0023] Reference Figures 1-5 The first shaft 3 is made of SK95 material, and the second shaft 4 is made of S45C material. Both internal hexagon bolt holes 5 are threaded with hexagon bolts for fixing the device and the external clamping plate. The main body is equipped with a stroke adjustment structure, which can adapt to the support requirements of workpieces of different heights by adjusting the movement stroke of the shaft. The shaft is equipped with an M5×0.8 thread structure for connecting external accessories. The applicable air pressure range of the pneumatic drive mechanism is 0.3~1.0MPa, and the corresponding support force is 300~500N.

[0024] Specifically, the first shaft 3 is made of SK95 material with a diameter D=8mm. It features an M5×0.8 thread structure and a shaft locking interface 2, allowing direct contact with the workpiece for support. SK95 material has high hardness and good wear resistance, capable of withstanding workpiece pressure without easy wear. The thread structure facilitates the connection of external accessories such as support heads, adapting to different workpiece shapes. The shaft locking interface 2 connects to the pneumatic drive mechanism, receiving pneumatic signals to lock / unlock, ensuring stable support contact, reducing wear and deformation over long-term use, and enhancing versatility through accessory connections. The second shaft 4 is made of S45C material and is located within the first shaft 3. The second shaft 4 transmits the support force. S45C has good rigidity, enhancing the first shaft 3's resistance to bending and preventing the shaft from being damaged by excessive force. The large and curved shaft enhances its overall load-bearing capacity, ensuring stable transmission of support force to the workpiece and preventing support offset caused by shaft deformation. The main body features a stroke adjustment structure, allowing the shaft's travel distance to adapt to workpiece support requirements of varying heights. A pneumatic drive mechanism connects to the shaft locking interface 2, operating at 0.3–1.0 MPa. The shaft moves axially along the main body by a stroke S = 3 mm based on air pressure variations. When the air pressure reaches the set value, the shaft locks; when the air pressure is released, the shaft opens with a lifting force of 1–1.9 N provided by a built-in spring, enabling automated shaft operation. 0.3–1.0 MPa air pressure corresponds to a support force of 300–500 N, which can be precisely adjusted according to workpiece weight to prevent insufficient support force from causing workpiece swaying or excessive support force from causing deformation.

[0025] This utility model proposes a pneumatic auxiliary support device that achieves automatic shaft locking through a pneumatic drive mechanism, avoiding the force fluctuations caused by manual operation. The high-strength materials used in conjunction with the shaft (SK95) and internal shaft (S45C) ensure stable transmission of support force, effectively preventing workpiece vibration and deformation, and improving machining accuracy. Pneumatic control enables rapid locking and unlocking of the shaft without manual adjustment, reducing work steps and improving workability. Furthermore, the adjustable stroke adapts to different workpieces, enhancing versatility and further improving work efficiency. Pneumatic drive avoids direct manual contact with moving parts, and the material selection and structural design reduce the risk of wear and tear over long-term use, decreasing the probability of failure.

[0026] Working principle: The main body 1 is made of aluminum alloy, which makes the body lightweight, easy to install and reduces the load on the fixture plate. When in use, the upper end face of the main body 1 is fixed with a first shaft 3. The first shaft 3 is internally equipped with a second shaft 4. The first shaft 3 and the second shaft 4 are made of different materials, but both are high-strength materials, which can stably transmit the supporting force and effectively prevent workpiece vibration and deformation. When in use, the device is fixed to the fixture plate with hexagonal bolts 5. After the device is fixed, the workpiece is placed in the support position. The shaft structure moves with the workpiece position and contacts the workpiece under the action of the spring lifting force.

[0027] Pressurization is applied to the shaft locking interface 2 by the pneumatic drive mechanism, which locks the first shaft 3 and provides a support force of 300-500N to stably support the workpiece. After processing is completed, the pneumatic pressure is released, the shaft is loosened, and the workpiece is removed.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
