FIELD OF INVENTION
[002] The present subject matter described herein, in general, relates to locating fixtures of power train brackets in Main Frame of Motor Grader equipment and more specifically relates to locating and clamping fixtures of power train brackets in Main Frame of Motor Grader equipment.

BACKGROUND OF THE INVENTION
[003] The mounting system of Engine, Transmission and other aggregates are inter-linked and together constitute a Power train layout. The location of seating of these aggregates in main frame needs to be accurate, precise and should be within the tolerance limit specified in drawing. Hence the drawing specification calls for controlled process that can be achieved through machining of these seating locations in main frame. However, welding of these brackets causes distortion of the structure and also machining of structure leads to higher cost and higher cycle time.
[004] Thus, as an alternative solution, a locating fixture is developed which can be used for locating pre machined mounting brackets on frame and subsequently joining by welding process and clamping fixture to control the welding distortion meeting the drawing specifications.

OBJECTS OF THE INVENTION
[005] Main object of the present invention is to develop a locating and clamping fixture to locate power train layout.
