Week 11- Assembly Workbench

PROJECT: Assembly workbench

OBJECTIVE:

• CAD modeling for the given Quick return mechanism and CV joint
• Create an assembly design for those part models
• Create a 2D drawing

QUICK RETURN MECHANISM

A quick return motion mechanism is used in the shaper and slotter machine in which the circular motion is converted into reciprocating motion so that the slider moves forward and backward. In the forward direction, the cutting process occurs while in return there is no such cutting.

CV JOINT

Constant-velocity joints (also known as homokinetic or CV joints) allow a drive shaft to transmit power through a variable angle, at constant rotational speed, without an appreciable increase in friction or play. They are mainly used in front-wheel drive vehicles.
