The Strength Analysis of CNC Machine Tool Hydraulic Automatic Centering Fixture

Abstract

CNC machine tool hydraulic automatic centering fixture is a kind of hydraulic automatic control fixtures, and installed on the tailstock inner clamp, have accurate and convenient clamping and good stability and high precision, suitable for excircle machining in long sleeve workpiece. In order to ensure the strength of the fixture meet the requirements, The force analysis on its structural analysis, applied mechanics method for strength calculation, and the use of Solidworks 3D Simulation software for finite element analysis, the results show that the clamp strength meet the design requirements.
