Fluid Expansion Clamp for Car Lathe

A liquid expansion fixture for lathe grinding machines is a high-precision fixture specifically designed for lathe grinding operations, utilizing the liquid expansion principle for clamping and positioning workpieces. The following is a detailed introduction to the liquid expansion fixture for lathe grinding machines:

Operating Principle

The working principle of hydraulic胀紧 fixtures for lathe machines is based on the static pressure expansion technology of liquids. When the fixture is subjected to pressure, the hydraulic medium generates pressure under the action of the pressure mechanism, forcing the deformation elements (such as elastic sleeves or expanding sleeves) to uniformly deform elastically over the entire clamping range in a 360° circumferential direction. This achieves tightness on the workpiece's locating holes or shafts. This clamping method ensures high precision positioning of the workpiece during machining while providing stable clamping force.
