Soft Wheel Hub Inner Hole, Liquid Expansion Clamp

A flexible wheel inner hole liquid expansion fixture is a specialized fixture used for the processing of flexible wheel inner holes, which employs the liquid expansion principle to clamp and locate the workpiece. The following is a detailed analysis of this fixture:

I. Working Principle

The working principle of the liquid expansion fixture is based on the static pressure expansion technology of liquids. When pressure is applied to the liquid inside the fixture, the hydraulic medium generates pressure under the action of the pressure mechanism, forcing the deforming element to uniformly deform elastically in all 360° circumferential directions within the clamping range, thereby achieving tightness on the locating holes or shafts of the workpiece. This clamping method offers high clamping positioning accuracy and significantly enhances the precision and quality consistency of the workpiece processing.

II. Product Features

1. High-precision clamping positioningHydraulic胀紧 fixtures provide high-precision workpiece clamping and positioning, ensuring stability and accuracy during the machining process.

2. Evenly distributed clamping forceDue to the action of the liquid expansion principle, the clamping force distribution of the fixture is even, preventing deformation or damage to the workpiece caused by uneven clamping force.

3. Adaptable: Liquid-filled clamping fixtures can achieve "variable diameter clamping" by utilizing accessories such as diameter-changing springs, spline springs, etc., and are suitable for processing workpieces of various specifications.

4. Easy to operateThe clamping and release operation of the fixture is simple and quick, reducing the difficulty and time cost of operation.
