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

AIM: To create clamp and pin unit 2D drawing for the required 3D model and create separate child parts.   SOFTWARE: CATIA V25   INTRODUCTION: A Fixture is a device that holds the workpiece or pieces in place while it’s being worked on. It holds it in place by arresting all the degrees of freedom using the…

AIM: To draft a Key sheet, Base unit, and Fix pin unit designs with all required child parts.   SOFTWARE: CATIAV25   INTRODUCTION:   Body in white (BIW) refers to the stage in automobile manufacturing in which a car body's components have been joined together, using one or a combination of different techniques:…

WHAT ARE DRAWING TEMPLATES?   Drawing templates are the basic drawing standards for a specific customer. Drawing templates are used to detail the different parts and features of the unit. Templates are used to denote various details and features including tolerances, measures, finishes, name of parts and assemblies…

Aim:  To perform 3D finishing and create rough locators for the assembly fixture.    Introduction:  It is the process where the fixture is checked in various parameters like hole concentricity, machining area marking, resolving clashes etc. This is the stage in the process where the position of the rough locators is also…

AIM: Design a base unit with all required weldments and pedestals as required by the fixture. INTRODUCTION: A base unit is a steel or aluminium plate of 20-40mm to which all other pin and clamp units are attached. It must also provide space for parts like a pneumatic controller, eye bolts, pneumatic cable trunking paths…

OBJECTIVE: Design 3 different types of Pin-Clamp Unit with different Riser, Blade and Clamp Arm for the given Car Panel.   SOFTWARE: CATIA V5 R21   PARTS SWIVEL CLAMP:   Clamp Cylinder: Clamp cylinder uses compressed air to actuate a piston that produces a force linear on the required part. Pneumatics are…

HOOD DESIGN AND DEVELOPMENT   Objective:             Design and develop a hood for a vehicle with reference to the provided outer panel design and provide requisite reinforcements and strengthening structures per required safety regulations, NVH limitations and design constraints.  …

UNDERBODY COATING   Underseal (often called undercoating in the U.S.) is a thick resilient coating applied to the underbody or chassis of an automobile to protect against impact damage from small stones, which would rapidly chip ordinary paint, allowing rusting to begin. The rate at which vehicles corrode is dependent…
