Week 5:- Rest Unit & Clamp Unit Design Challenge

Rest unit:

This is a unit to designed for support car pannel using Myler/NC Block rest component is rested only, no upper clamp/force applied there,the purpose of design this unit only for rest car panel.Locating ,clamping and test unit also combined in one unit to reduce cost.There is no cylinder attached to it,rest myler,blade,risers are the differernt parts of rest unit.Rest unit is also divided into simple support unit,multiple support units and retractable support units.

Clamp unit:

This is a unit to designed to clamp/hold the car panel with Myler/NC Blocks,rest by using a penumatic cylinder.clamp arm,finger,rest/backup,Lblock,Shims,Riser,penumatic cylinders are the typical parts of clamp unit.The opening of clamp should 90deg.In the clamp unit one side shim is more enough because it will restrict translational motion in upward direction and downard direction only.There is another type of clamp unit called swivel type.There is a pivot pin around which clamp arm rotates.

Purpose of clamp and rest unit-

- It is securely hold the workpiece in position without obstructing the production process.

-It pevents distortion during the welding process and other process.

Clamping:

The process of holding the workpiece in the jig/fixture is called clamping.The primary devices used for holding the workpieces are clamped/clamp unit.

Resting:

The car panel will rest on the rest unit,It resist the clamping force of the force exerted by the clamp cylinder and thus clamps the car panel.

There is 2types of force acting on it. i-Clamping force, ii-Holding force.

1. It signifies the force applied to the workpiece by the drive mechanism via the clamp arm during griping or clamping operations.
2. Holding force is denoted the maximum force after locking the knee-lever.If the holding force specified in the technical details is exceeded,it will result in the destruction of the mechanism.
