CONSTRUCTION

 

The automotive hub stand was made out of 6061-T6 Aluminum. The hub stand consists of the following parts:

 

Part 1: Hub Plate

Part 2: Hub Plate Member

Part 3: Hub Stand Central Frame

Part 4: Base Plate

Part 5: Hitch Pin/Cotter pin

Part 6: Spring loaded roller ball

Part 7: Screw Bolt

Part 8: Locknut

 

The hub plate was welded onto the hub plate member. The hub plate member slides into the hub stand central frame much like a hitch and receiver. The pin holds the hub plate member at the desired height. The hub stand central frame was welded on to the base plate. Lastly, the spring-loaded roller balls were attached to the base plate via screw bolts and locknuts.

 

Manufacturing Issues   

There were two welding operations needed in the construction of the hub stand. The hub plate was welded to the hub plate member and the hub stand frame was welded on to the base plate. The weldments were completed with the help of Matt and Trevor. All machining operations were completed on the manual milling machine, drill press and lathe available at CWU using the knowledge and skills gained from MET 423. The fillets on the base plate and the hub plate member were not machined due to time constraints and lack of proper tools. Most of the parts received from OnlineMetals.com were not cut to the right dimension. The base plate was too thick for the screw bolts and nuts to work so it needed to be faced on both sides to bring the overall width down to the acceptable dimension. This was done using the manual-milling machine. The hub plate member would not slide into the frame so it had to be faced on two sides on the manual milling machine. Countersinks were added to the holes drilled on the hub plate member and hub stand frame in order to assist the movement of the hitch pin. The hub plate had to be faced on both sides using the lathe machine due to the fact that the saw blade left a very bad finish. 15-degree chamfers were machined onto the top edges of the hub plate member in order to avoid possible fitment issues with the hub of the vehicle. This was done using the manual milling machine and angle dies.
