[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-6 As shown, this utility model provides a technical solution: a quick clamping device for grinding the outer diameter of a valve core, including a clamping assembly 1, an installation assembly 2 at one end of the clamping assembly 1, a clamping pad assembly 3 on the installation assembly 2, a cylinder 102, an installation seat 103 at one end of the cylinder 102, an installation groove 201 and an installation block 207, limit strips 208 on both sides of the installation block 207, the installation block 207 and the limit strips 208 slidingly mounted inside the installation groove 201, a clamping head 209 on the side of the installation block 207, a fixing frame 202 on both sides of the installation groove 201, a limiting plate 203 movably mounted inside the fixing frame 202, a limiting rod 204 penetrating inside the installation groove 201, a handle 205 on one end of the limiting rod 204, and a fixing sleeve 206 sleeved on the other end of the limiting rod 204.

[0024] In this embodiment, by sliding the mounting block 207 and the limiting strip 208 inside the mounting groove 201, it is convenient to maintain and replace the clamp head 209. The movable limiting plate 203 moves inside the fixed frame 202, which helps to limit the clamp head 209. Then, the hand handle 205 uses the limiting rod 204 to pass through the mounting groove 201 and the mounting block 207, which helps to further limit the clamp head 209, ensuring the stability and reliability of the clamp head 209 installation. The operation is convenient and fast, which facilitates the maintenance and replacement of the clamp head 209, shortens the maintenance and replacement time, reduces the equipment downtime, and thus improves production efficiency. At the same time, it is convenient to replace different clamp heads 209 according to production, which improves the versatility and flexibility of the equipment. The limiting is achieved by using the fixed sleeve 206 to snap-fit ​​the limiting rod 204.

[0025] Example 2: As Figures 1-6 As shown, the clamping pad assembly 3 includes a clamping pad 301, with multiple anti-slip strips 302 distributed on the side of the clamping pad 301. The clamping pad 301 is installed on the side of the clamping head 209. Guide grooves 303 are provided on both sides of the clamping head 209. A limit frame 304 is installed inside the guide groove 303. A support frame 306 is installed on the side of the clamping head 209. A fixing rod 305 passes through the inside of the support frame 306. A delivery pipe 104 is connected to the bottom of the cylinder 102. An air pump 105 is installed at one end of the delivery pipe 104. A clamping seat 101 is installed on the outside of the air pump 105.

[0026] In this embodiment, the air pump 105 operates to generate gas, which is then delivered to the cylinder 102 via the delivery pipe 104. The cylinder 102 then extends and pushes the mounting base 103, causing the clamping head 209 to clamp the valve core. The clamping pad 301 is installed on the side of the clamping head 209. The clamping pad 301, together with the anti-slip strip 302, helps to avoid direct contact between the clamping head 209 and the valve core, reducing the possibility of scratches and indentations on the valve core. At the same time, it helps to increase the friction between the clamping head 209 and the valve core, preventing the valve core from sliding during processing and ensuring the stability of the valve core during processing. This is beneficial to improving the accuracy of external cylindrical grinding. By pulling out the fixing rod 305 and then pulling the limiting frame 304 to slide inside the guide groove 303, it is easy to release the limitation on the clamping pad 301, making it convenient for maintenance and replacement of the clamping pad 301.

[0027] The working principle of the embodiment is as follows: in use, first, the air pump 105 works to generate gas, so that the gas is delivered to the air cylinder 102 through the delivery pipe 104, and then the air cylinder 102 is extended to push the mounting seat 103, so that the clamp head 209 clamps the valve core, the clamping pad 301 is installed on the side of the clamp head 209, and the clamping pad 301 cooperates with the anti-skid strip 302, which is beneficial to avoid the direct contact between the clamp head 209 and the valve core, reduces the scratch and indentation of the valve core, the fixed rod 305 is pulled out to the outside, then the limiting frame 304 is pulled to slide in the guide groove 303, which is beneficial to release the limiting of the clamping pad 301, and the clamping pad 301 is convenient to maintain and replace, when the clamp head 209 is maintained, the mounting block 207 and the limiting strip 208 are slidably installed in the mounting groove 201, which is convenient to maintain and replace the clamp head 209, the limiting plate 203 moves in the fixed frame 202, which is beneficial to limit the clamp head 209, then the handle 205 penetrates into the mounting groove 201 and the mounting block 207 through the limiting rod 204, which is beneficial to further limit the clamp head 209, and the clamp head 209 is convenient to maintain and replace.

[0028] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present application still belong to the protection scope of the present application.
