Fixture Development for Straightening Operation of Front Axle Beam

Abstract

In front beam axles industries, axles are manufactured and machined. During machining process, the axle moves
through straightening process where the axles are straightened. Different axle with different dimensions is mounted on the
same machines with the help of fixture. So we have to design fixtures for the axle (Die No. 2675) for straightening operation.
This paper analyzes the modification of the existing fixture by incorporating an electric motor in the screw in order to make
fitment easier. In this modified design, the power screw is rotated through it hydraulic motor. Connecting gear rotated with
required speed reduction and increased torque to drive the power screw. The significance and purpose of this work is to
modify the existing clamping procedure in order to make the operation easier, safer and more reliable in order to reduce
health risks especially back ache problems associated with doing work in a bent or squatting position for a long period of
time for workers.
The designing of axle beam and fixtures are carried out by creating solid 3D models in SOLIDWORKS software.The
dimensions of beam geometry are found out for best placing dimensions for fixtures. The designed fixture will also save time
and requires less human energy to operate. The design when adopted will effectively curb the problems associated with
Ergonomics - which is a fundamental concept of the design process. The Design a mechanical fixture is for straightening
operation for front axle beam Military tank having weight 147kg.
