DESIGN AND DRAFTING OF THE QUICK RETURN MECHANISM AND THE CV JOINT

Objective:

The main objective of this project is to design and draft the quick return mechanism and the CV joint using Catia V5

Introduction:

The quick return mechanism is used in the place where is quick return of the tool is needed while machining process, it saves more time in the machining process. The CV joint is used to transmit torque in an angled direction without any loss of power, the propellor shaft in a vehicle is the best example with has an CV joint.

Methodology/approach:

For the design of the quick return mechanism:

• First, the parts of the quick return mechanism should be created with the help of the dimensions provided in the 2d drawings. It has five parts; all the five parts should be modelled using the part design.

• Then create an assembly for the parts designed, constrain the following parts to the faces where the parts are to be fixed.

• Once the assembly is created, then use the 2D drafting application to get the detailed drawing in the drawing sheets. These 2D drawing sheets are used for the further validation and manufacturing process.

For the design of CV joint:

• First, the parts of the CV joint should be created with the help of the dimensions provided in the 2d drawings. It has three parts; all the three parts should be modelled using the part design.

• Then create an assembly for the parts designed, constrain the following parts to the faces where the parts are to be fixed.

• Once the assembly is created, then use the 2D drafting application to get the detailed drawing in the drawing sheets. These 2D drawing sheets are used for the further validation and manufacturing process.

Conclusion:

The design and drafting of the quick return mechanism and the CV joint are completed using Catia V5.
