AIM:-To create assembly for Quick Return mechanism and C.V. JOINT.

INTRODUCTION:-

1)QUICK RETURN MECHANISM:-

The Quick return mechanism is the inversion of a single slider crank chain.The main purpose of this mechanism is to convert the rotary motion of the crank into reciprocating motion of the ram.A Quick return mechanism is used in the shaper and slotter machine.

There are three types of Quick return mechanism:

1. Whitworth Quick Return mechanism

2.Crank and Slotted Link Mechanism

3.Hydraulic Drive

2)CONSTANT VELOCITY JOINT:-

C.V. joint or constant velocity joint, is part of a drive shaft,the shaft that attaches to a car's transmission at one end and the wheel at the other.These joints are designed to be able to bend in any direction while continuing to turn the drive wheels at a constant velocity.

The CV joints are needed to transfer the torque from the transmission to the drive wheels at a constant speed,while accomodating the up-and-down motion of the suspension.

WORKBENCHE USED:-

1.Part Modelling

2.Assembly

3.Drafting

1.Part Modelling:- Create a solid part model using input dimensions.

2.Assembly:- Assembly modelling is the process of creating designs that consist of two or more components assembled togetherat their respective work positions.The components are brought together and assembled in Assembly design workbench by applying suitable constraints to them.

The method of invoking the Assembly Design workbench is by choosing start>Mechanical Design>Assembly Design from the menu bar.

Types of Assembly Design Approach:-

In CATIA you can create assembly models by adopting two types of approaches.The first approach is the bottom-up approach,and second one is the top-down approach.

3.Drafting :- Create drawing of assembly and part individually.
