Week 4:- Pin Unit Design Challenge
AIM
To design the fixed and retractable pin units with round and daimond ppins to the car panel using CATIA V5.
Q-12 Describe Fixed Pin units & their purpose
Fixed Pin Uni t is non movable locating unit which arrest movement of component in fixture. Fig. shows an example of fixed pin unit. It consist of pin, pin retainer, blade, two way shims or spacer which control X, Y direction adjustment, block and riser.
PurP-ose of Fixed Pin Unit are as below:
- Main purpose of fixed pin unit is to locate component
- This unit is used arrest 6 degrees of freedom of component
- Two pins are used to locate First pin restricts 4 translational motion and other one restricts 2 rotational motion.
