The Soft Wheel External Circle Liquid Expansion Clamp is a specialized fixture designed for the external circle processing of soft wheels, utilizing the liquid expansion principle for clamping and positioning the workpiece. The following is a detailed analysis of this fixture:

Operating Principle

The principle of operation for hydraulic胀套 is primarily based on the thermal expansion and contraction properties of liquids, as well as static pressure expansion technology. When heated, the liquid expands, increasing the clamping force of the fixture; conversely, when cooled, the liquid contracts, reducing the clamping force. In the external diameter machining of flexible wheels, the hydraulic胀套 is filled with a certain amount of liquid (usually water or oil) and connected to the control system via pipes. To clamp a workpiece, the control system raises the liquid temperature or applies pressure, causing the liquid to expand and push the fixture to tighten the workpiece; to release the workpiece, the liquid temperature is lowered or pressure is released, causing the liquid to contract and the fixture to loosen.
