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

Design 3Different types of Swivel Clamp unit with Different Riser blade and Clamp Arm for the given car panel maintain the stock as 100mm

Aim/Introduction/Objective

In this Challanges we have desig three different types of swivel clamp unit with different riser,blade and clamp arm for the given car panel design. a pin-clamp unit for a given car panel with the optimum use of material and space constraint also considering panel thickness 1mm unit

REPORT & THEROY

3-2-1 Prinicple achievement

the 3-2-1 principle method is a work holding principle where three pins are located on the 1st prinicple plane is either XY.YZ.ZX and two pin are located on the 2and plane which perpendicular to the 1st plane and last one pin on the plane which is mutually perpendicular to the 1st and 2plane . The ultimate goal is to constain the movement of the workpieces along all three axis.

Round locating

The pin added in the locating of the hole restricts the axial movement of two perpendicular axes . This restricting four degrees of freedom.

1.Round locating pin

The round locating pin added to the slot in order to restrict the remanining radical movemet in both clockwise and anticlock wise

Therefore restricts the remaning two degree freedom

Clamp unit

Clamp unit is a unit designed to clamp /hold the car panel with Nc block/Mylar/rest by using a pneumatic clamp cylinder and below are the different parts of a clamp unit in general .Usually clamp open position is 90 degree finger attached to clamp mylar. clamp unit shim to one side is more enough because it will restrict translation motion in upward and downword direction and only . there is another type of clamp unit known swivel type . there are pivot pin around which clamp arm rotate

Factor Should be considered while designing a calmp unit

1. There should be adequate spaces between the cylinder and another part likes riser car panel because cylinder mover and swing while opening and closing

2. Pin Clamp unit used where two panels and component are locating welding

3. Clamping make in such way that it clamp two car panels at once

4. All parts should snap and butt properly to each other

5. Make sure that parts of the clamping unit are 10 to 12 mm away from car panel so they do not damage car panel

6.Avoid any clash it will not ariser issuse at assembly

Part of Clamp unit

Clamp cylinder : Generally Standar part

Nomenclature of cylinder as below

CKG1:Series of cylinder

B:clevis

63:Bore size

100:Stroke of Cylinder

Y:End bracket I.e double knuckle joint
