1. Spring-Actuated Clamping Mechanism (CAD)
This project focused on the 3D modeling and mechanical detailing of a custom clamping fixture designed to secure cylindrical workpieces.
3D Assembly & Kinematics
The mechanism features a spring-loaded cylindrical housing (rendered with transparency for internal visibility) connected to a pivoting upper clamping lever via a clevis and linkage system. A V-block locator is integrated at the base to ensure precise alignment of the clamped components.
Technical Drafting & GD&T
To transition the digital model into manufacturing, I generated production-ready 2D technical drawings adhering to standard engineering conventions. These drawings detail critical dimensions, geometric tolerancing, and surface finishes required for machining.
-
Klemmhebel (Clamping Lever): Specifies precise hole locations with
H7fit tolerances for accurate pin insertion, alongside detailed section views (A-A) to define internal geometry and chamfers.
-
Verbindungsstück (V-Block Locator): Highlights a 90° V-groove with centered
M3tapped holes, complete with 120° countersinks for flush hardware seating.
-
Zylinderdeckel (Cylinder Cap): Details a circular flange with a defined pitch circle diameter for the mounting holes, ensuring concentricity with the main cylinder housing.
-
Zylinderstange (Piston Rod): Specifies a surface roughness of
Ra 3.2for smooth linear actuation, incorporating defined tolerances (+0.15) and 1x45° chamfers for ease of assembly.
2. Custom Machined Aluminum Fixture
Moving from digital design to practical fabrication, this project involved the physical machining of a custom aluminum stand.
The manufacturing process required precise milling and turning operations to achieve the necessary surface finish and dimensional accuracy. The final assembly features a rigid vertical support, a turned top collar, and a customized baseplate finalized with a precise surface engraving of my name and location (“Arlind Tuzi Toronto”).
