DESIGN OF FIXTURE OF CONNECTING ROD FOR BORING OPERATION

Connecting rod is very important part of engine. It should be accurately machined with the acceptable tolerance. Also the fluctuations of dimensions in work-piece to work piece should be minimum so that it will be easier to assemble in engine. But it has been observed that the required dimensions for the bolt diameter and smaller end diameter for the connecting rod are not continuously achievable by using the existing fixture. The diameters required of the bolts and the smaller end of the said connecting rod are 10±0.05 mm and 24±0.01 mm respectively The aim of this project is to design and development of a new fixture for machining (Boring) operation using designing software's i.e. Pro E and analysis using ANSYS ,which can eliminate the said problems. And the production rate will also increase up to 15% which is quite objective. So for that, a new hydraulic fixture is designed and observed that dimensional accuracy, increased production rate up to 15% and more output per day with boring operation. Which defines process is satisfactory enough and validates the project.
