DESIGN AND DEVELOPMENT OF HYDRAULIC FIXTURE FOR MACHINING HYDRAULIC LIFT HOUSING

In machining fixtures, minimizing workpiece deformation due to clamping and cutting forces is essential to maintain the machining accuracy. The recent trends in industry are towards adopting the hydraulic techniques, because it save time generates accuracy and it is having some flexibility. Hydraulic Fixture is major application in the field of designing, where in several software’s are available for the purpose of design. Hydraulic lift housing is engine part of an agricultural tractor which plays an important role in application of lifting trolley of tractor and machining of hydraulic lift housing is a important task. Loading and unloading of workpiece in manual clamping is time consuming process, so reducing machining time, set up time etc is a main aim of process. The job having cylindrical shape, this is a challenging task for design engineer, hence hydraulic fixture design is incorporated in manufacturing industry. Except toggle clamp, no other option is available to hold cylindrical object, hence special type of fixture is design for this case, which can be used for machining of hydraulic lift housing, Fixture reduces operation time, increases productivity, and best quality of operation is possible. The project deals with the designing of different parts of fixture assembly, 3D modeling by using Pro-E WILDFIRE 5.0, finite element analysis of hydraulic lift housing by using ANSYS software
