Yoke is a part of Drive Shaft which is required when power is to be transmitted from engine to differential of an automobile. A yoke for a universal joint is used to join fork halves, each comprising a base component and a bearing component. During drilling and spot facing on the flanges of Yoke, vibrations takes place and it leads to tool breakage. Hence the tool changing time is increased. Thus there is a need to design a fixture to nullify the problems.We have designed such a fixture which will carry out the drilling operation efficiently. The newly designed fixture uses an insert type of drilling U drill which removes the material as per requirement, which reduces the vibrations and tool breakage and ultimately reduces the tool changing time.
Spot Facing: Spot facing is the operation of smoothing and squaring the surface around and at the end of a hole so as to provide a smooth seat for a nut or for the head of a cap screw. Spot facing is generally done on castings and forgings.
