Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0022] Combination Figure 1 A pneumatic chuck device with adjustment and correction functions includes a pneumatic chuck 1, an air supply pipe 2 arranged on the outer surface of the pneumatic chuck 1, and an air source 3 arranged at one end of the air supply pipe 2. The inside of the pneumatic chuck 1 is provided with a correction component 4 for guiding the workpiece to align with the inside of the pneumatic chuck 1.

[0023] The utility model is further described below in conjunction with embodiments.

[0024] Embodiment 1:

[0025] See also Figure 1-Figure 4The correction component 4 includes a chuck body 41 arranged inside the pneumatic chuck 1, a spring A42 arranged inside the chuck body 41, and a positioning pin 43 arranged at one end of the spring A42, the positioning pin 43 is plugged into the inside of the coil drum, a conical guide plate 44 is arranged at one end of the pneumatic chuck 1, a threaded hole 45 is opened on the outer surface of the chuck body 41, and a miniature bolt 46 is connected to the inner thread of the threaded hole 45, and a clamping block 47 is arranged at one end of the miniature bolt 46, and one end of the clamping block 47 is connected to the coil drum. When the device is working, the reel is guided to move from the conical guide plate 44 to the pneumatic chuck 1, and the inside of the reel is plugged into the positioning pin 43, and at the same time the spring A42 is compressed, and then the air source 3 supplies air to fix the reel, and then according to the rotation of the micro bolt 46, the clamping block 47 is close to the outer surface of the reel, so as to fine-tune the clamping force to ensure that the workpiece is stable and its surface is not damaged. Therefore, it not only improves the accuracy of workpiece positioning, but also reduces the risk of damage during the clamping process.

[0026] A wear-resistant layer 5 is provided inside the chuck body 41. The wear-resistant layer 5 is a component made of cemented carbide and can effectively resist wear caused by high-speed rotation or frequent use, thereby extending the service life of the pneumatic chuck 1 and maintaining its clamping accuracy, reducing maintenance costs and equipment downtime.

[0027] The pneumatic chuck 1 includes a flange 11, a sleeve A12 arranged on one side of the flange 11, a sleeve B13 arranged inside the sleeve A12, and a jacket 14 arranged inside the sleeve B13. The jacket 14 is located on the outer surface of the chuck body 41. The outer surface of the sleeve A12 is provided with an air connection head 121, and the air connection head 121 is connected to the air supply pipe 2. The overall structure is installed on the machine tool through the flange 11, and then the compressed gas is supplied to the inside of the sleeve A12 through the air supply pipe 2 through the air source 3, so that the sleeve B13 moves up and down inside the sleeve A12. Therefore, when the sleeve B13 moves up, the jacket 14 also moves up and wraps the chuck body 41, so that the workpiece inside the chuck body 41 is tightened, thereby achieving the clamping effect of the pneumatic chuck.

[0028] A sealing ring 6 is provided between the sliding sleeve A12 and the sliding sleeve B13 to prevent gas leakage and improve air tightness.

[0029] A gasket 7 is provided between the sliding sleeve B13 and the clamping sleeve 14 to reduce the gap between the two and increase stability, thereby reducing wear and further improving the life of the clamping device.

[0030] A spring B8 is provided on one side of the sliding sleeve B13, and one end of the spring B8 is fixedly connected to the bottom of the chuck 14, providing a rebound force, which helps to quickly return to the original position after the air pressure is released, while ensuring the smooth movement of the chuck.

[0031] Specifically, when the device is working, the overall structure is first installed on the machine tool through the flange 11, and then the reel is guided to move from the conical guide plate 44 to the pneumatic chuck 1, and the inside of the reel is plugged into the positioning pin 43, and at the same time the spring A42 is compressed, and then the compressed gas is transmitted to the inside of the sleeve A12 through the air supply pipe 2 through the air source 3, so that the sleeve B13 moves up and down inside the sleeve A12. Therefore, when the sleeve B13 moves up, the sleeve 14 also moves up and wraps the chuck body 41, so that the workpiece inside the chuck body 41 is tightened, realizing the clamping effect of the pneumatic chuck, so that the reel is fixed, and then according to the rotation of the micro bolt 46, the clamp block 47 is close to the outer surface of the reel, so as to fine-tune the clamping force. The degree of tightening is ensured, and the workpiece is ensured to be stable without damaging its surface. Therefore, it not only improves the accuracy of workpiece positioning, but also reduces the risk of damage during the clamping process. In addition, since a sealing ring 6 is provided between the sleeve A12 and the sleeve B13, gas leakage can be prevented and the air tightness can be improved. Since a gasket 7 is provided between the sleeve B13 and the jacket 14, the gap between the two is reduced, and the stability is increased, thereby reducing wear and further improving the life of the chuck device. At the same time, since a spring B8 is provided on one side of the sleeve B13, one end of the spring B8 is fixedly connected to the bottom of the jacket 14, a rebound force is also provided, which helps to quickly return to the original position after the air pressure is released, while ensuring the smoothness of the chuck movement.
