Description

Technical Field

[0001] The utility model belongs to the technical field of valve sleeve processing and clamping, and particularly relates to a valve sleeve processing and clamping device. Background Art

[0002] The clamping device for valve sleeve processing is a device used to fix the valve sleeve during the processing. The valve sleeve is a component that connects the pipeline. During the processing, it is generally necessary to fix it on a workbench or fixture for processing operations. The traditional clamping device uses a fixed fixture or chuck to clamp the valve sleeve, but due to the different pipe diameters of the valve sleeve, the clamping structure needs to be constantly adjusted. The problem of inconvenient clamping adjustment of the clamping structure due to different valve sleeve diameters means that due to the different valve sleeve diameters, the traditional clamping device needs to frequently adjust the size of the clamping structure, which makes the operation cumbersome and time-consuming, and is not conducive to improving work efficiency. This not only increases the labor intensity of workers, but may also affect the accuracy of clamping and processing quality. Utility Model Content
