Week 6:- Clamp Unit & Pin-Clamp Unit Design Challenge
AIM: Design two different types of swivel clamp unit and one swivel clamp _pin unit for the given car panel using CATIA SOFTWARE.
SWIVEL CYLINDER CLAMP UNIT : It is a unit to hold the car panel using Mylars which exerts force on the car panel by means of swivel cylinder
PARTS OF SWIVEL CYLINDER CLAMP UNIT
1- Mylars : It is a L block with square cross section which is used to hold the car panel by exerting direct pressure on the top of the car panel.
2- One way shim pack : It is used to adjust the position of Mylar finger in one direction (" here vertical direction ").
3- Clamp arm : It is a slender bar of rectangular cross section which is directly pivot to the swivel cylinder oscillating in the YZ plane (here in design) used to exert pressure on the MYLAR.
4- Stopper : It is used to support the clamp arm and prevent the clamp arm from excessive deflection also in order to restrict the linear motion of the stopper on the clamp arm we made a cut out of required diemension to limit the motion of the stopper.
5- Pivot arm : It is a link attached between the clamp arm (welded / pivoted) and blade (pivoted / welded) the main function of it is to limit the opening angle of clamp arm (upto 90 deg) and also help to maintain the required motion.
6- Swivel cylinder : It is a Pneumatic cylinder which govern the rotation of clamp arm and also provide the required force to hold the car panel.
7- Blade : It is a component which is attached to the riser and all the parts are attached to it because of this component we can use same riser for different height requirement for fixture.
8- Riser : It is a stand which supports all the above components.
9- Bush : It is used to avoid the wearing and tearing of elements if there is a relative motion exists between them.
10-Lock pin : It is used to connect the pivot arm to the blade and allow the rotation of pivot arm with respect to the blade.
PARTS OF SWIVEL CYLINDER PIN CLAMP UNIT
Besides above mentioned parts we have Pin (round and Diamond), Pin retainer, two way shim pack , 2 L brackets which are directly attached to blade and L block as shown below.
1- Pin
a) Round pin.
b) Diamond pin.
2- Pin retainer
3- L-block with two way shim pack
4- L-bracket

CONCLUSION :
We successfully made two swivel cylinder and one swivel cylinder pin clamp unit considering all manufacturing aspect using CATIA SOFTWARE.
