A New Fixture for Automobile Belt Tensioner Brace

Abstract:

A type automobile belt tensioner brace parts need many times of the clamping in the process of machining, which will lead to the low accuracy ,low efficiency and high cost and so on. This paper based on the structural feature of the brace provided a special fixture for the brace and built a Petri nets model to describe the work process in detail by the analysis of the fixture‘s positioning ,the clamping process analysis and the clamping force analysis. Moreover , This fixture can clamp two belt tensioner brace at the same time during completing the three machining surface of workpiece without changing the fixture,which can clamp the workpiece more convenient with higher positioning accurate ,higher machinging accuracy and lower cost. This fixture has passed the practical proof , which provied a reference for designing a fixture to clamp a workpiece with more complex surface .
