Week 6:- Clamp Unit & Pin-Clamp Unit Design Challenge

Swivel Clamp Unit:

Swivel Clamp is used to clamp car panel or component in fixture with the help of pneumatic cylinders and clamps. Generally clamps open with 90 degrees. This unit requires adjustment in only one direction using shimpacks.

Different parts of Swivel Clamp Unit are as below:

1. Clamp Mylar/ Finger/ NC Block: This part is in actual contact with car panel as it hold or clamp the component.
2. Rest Mylar/ Finger/ NC Block: This part also is in actual contact with car panel as car panel rest on this part as shown in above image.
3. Clamp Arm: Clamp Arm is part on which clamp mylar is mounted. Basically this is standard part comes with cylinder.
4. BLADE: As shown in figure blades are bolted on riser.
5. RISER: Riser are used to increase height of unit and these are standard parts so need not detailed it or designed it.
6. Shim/Spacer: Shims or spacer are used to compensate tolerance stack up. In clamp unit we need to control only onw direction that are z using shims or spacer. Shims are generally thin sized plates used in group called Shimpack and spacer are used as single plate and can be machined accordingly.

3 Different types of Swivel Clamp Unit with Different Riser, Blade, and Clamp Arm for the given Car Panel:

A Pin-Clamp Unit for the given Car Panel:

PROCESS:

1. First of all I start designing from clamp and rest mylar.
2. Then design clamp arm as shown in images I pasted above.
3. Accordingly I designed riser and mount cylinder on it.
4. Then according to the cylinder stroke, adjust the whole unit for proper loading and unloading of car panel.
