The prompt
Design a compact mechanical welding torch carriage for a mechanical engineering graduation project. The machine is a torch-carrying trolley only, not a complete welding machine. Main components: 1. A rigid rectangular steel chassis with a compact open-frame structure. 2. Four track-gripping guide wheels, arranged as two pairs, to keep the carriage securely aligned on a metal track. 3. A geared electric motor mounted on the chassis. 4. A sprocket drive connected to the gearbox output shaft. 5. A metal track with a central row of equally spaced slots. The sprocket engages with the slots to propel the carriage along the track. 6. Adjustable wheel axles with adjustment bolts for alignment and clamping. 7. A vertical adjustable bracket to hold a welding torch. 8. A simple mechanical mounting plate for the motor and gearbox. 9. A protective cover around the sprocket and transmission where appropriate. The carriage should travel along a straight track and be adaptable to a flexible track that can follow the outside surface of a cylindrical tank. Create a realistic 3D mechanical CAD concept with clearly separated components, visible wheel-track engagement, realistic metal materials, and a practical manufacturable design. Show the chassis, wheels, sprocket, slotted track, motor, gearbox, and torch holder clearly. Do not add artificial intelligence, sensors, software, or unnecessary electronic systems. Do not assume final engineering dimensions. Use proportional placeholder dimensions suitable for later mechanical design calculations. Generate a 3D assembly concept with a clean isometric view and an exploded view if supported.
