Week 5:- Rest Unit & Clamp Unit Design Challenge

CLAMP UNIT:

Clamp Unit is used to clamp or hold the car panel or component in fixture with the help of mylars or NC blocks using manual or pneumatic clamp cylinder. This unit only restricts up and down motion of car panel. Following is the example of clamp unit having different component as shown in the diagram:

Different parts used in 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.

Following are the clamp units I have designed:

REST UNIT:

Rest unit is used to give support to the car panel or component. Hence also known as support unit. It consist of riser, rest mylar and shim or spacer for upward or downward adjustment.

Following are the rest units I have designed:
