Jaguar Land Rover JLR Spare wheel Assistor

SLIDE 2

Requirements: to pick all variants of spare wheel for L494 (Range Rover sport) X760 (new jaguar XE) and X761 (new Jaguar SUV), 8spare wheel variants in total ranging from a 20” alloy full size spare, to a pressed mild steel space saver spare. Wheels to be picked up horizontally from a delivery stillage and transferred into the rear of the relevant vehicle.

CLAMP JAW STRESS CALCULATIONS AND FEA

SLIDE 5

Clamped cross sections through worst case spare wheels to be handled

Outer nylon cone extends to allow for the difference in internal wheel bore diameters.

Central pin extends to open the jaws, and retracts to close the jaws, the clamp jaws are mechanically locked in each position so it will not drop the part in the event of complete and sudden air failure.

Rolls Royce Blade C-Scan AssistorRequirements: To pick flat pack blades from a “toaster rack” style stillage, rotate it 90° and place it submerged

in a water tank for the Rolls-Royce C-scan procedure to take place. The C-Scan is an ultrasonic scan of the

blade to check for impurities / defects / contaminants in the metal blades. Once the scanning operation was

complete, the assistor would then pick the submerged blade up out the C-scan tank, rotate by 90° and back

into the stillage.

The assistor was to handle all blades from all the Rolls-Royce engines from the Trent 500 to the Trent XWB , 8

variants in total with a maximum safe working load of 65kgs.

A few design requirements had to be considered before the design could begin:

• How would the performance of the pneumatic vacuum generator be affected when water is introduced into

the system?

• How would the vacuum cup performance be affected when picking up in a water filled environment.

• This was a very corrosive environment so the end effecter was to be made of stainless steel, all pneumatic

fittings were to be stainless steel, pneumatic cylinders were to be corrosions resistant, clean room and food

industry standard.

• To avoid any contaminants entering the C-scan tank all bearings and bushes had to be sealed and no oilite

bushes to be used.

• No silicone based materials were to be in contact with the blade, a nitrile-pvc vacuum cup from PIAB was

chosen.

Jaguar F-Type Coupe Body side assistor.

Requirements: To pick the F-type coupe aluminium body side panel from a delivery stillage, rotate it through 90° and

place on to the f-type coupe Body in white frame ready for the riveting/welding process to take place further down the

line.

One assistor on each side of the line for left and right hand side body panels.

Picking up on the body panels A-surface, care had to be taken to prevent any A-surface from being contacted by

anything other than soft nylon, polyurethane and rubber.

Control Scheme

• Press ‘brake’ lever on pick controls to release brakes

• Manoeuvre assistor over to the part in the stillage and visually locate assistor to the part using the nylon locators as guides.

• When satisfied that it is located, press both ‘Vac on’ finger levers to switch on the vacuum circuit

• When a successful vacuum has been reached the ‘Vac ok’ indicator will illuminate and automatically switch the assistor into the higher balanced load. Use ‘balance’ knob to adjust the balance trim as necessary.

* NB - If the part is not correctly located in the assistor it will not generate a successful vacuum, the ‘Vac ok’ indicator will not illuminate and the assistor will not switch to Load.

• Carefully remove the Assistor and component from the stillage and manoeuvre into a clear space ready for rotation.

• Press ‘brake’ brake lever to apply brakes and move into position in front of rotate handles.

• If necessary press brake lever from rotate handles to release brakes and readjust assistor position as necessary to clear any potential obstacles, then apply brakes again when you are satisfied all obstacles are clear.

• From rotate handles press the ‘enable’ lever along with ‘rot right’ lever to rotate part from pick to place position.

* NB – Brakes should be applied during the full rotation of the part to avoid assistor drifting into build fixture or stillage.

• Move into position in front of place handles, press the brake lever to release the brakes again and locate the part in the build fixture.

• Once located, press both release levers to switch off the vacuum circuit and release the part, this will automatically switch the assistor back to the lower balanced load.

• Move assistor to safe or parked position for repeat operation.

L538 (Evoque) and L550 (Freelander 3) Axle Lifter

SLIDE 40

Requirements: Design a frame manually operated lifting frame to pick the fully assembled axle assembly from build

fixture and transfer over to marriage tug using existing Demag electric hoist and existing overhead trackwork. There was

no pneumatics in the axle build area so any clamps had to be manually operated.
