Part Positioning Solutions

Turntables

• For small- to medium-size parts
• Operator safely loads/unloads part(s) on one side of the positioner (outside the robot’s work envelope), while the robot welds part(s) on the other side
• Metal arc screen divider creates barrier; safeguards operator from arc flash
• Run same part(s) on both sides of positioner or run one part on Side A and different part on Side B
• H-frame table top; low-inertia and quick-change tooling
• Options: tooling plates, 72" table top and slip rings for utilities

Rotating Turntables

• Medium- to high-volume production
• Provides large turning diameter for shorter parts
• Three servo-motor control
  • All axes can turn simultaneously while indexing
  • Operator can jog station axis while robot welds
• Rotory axis motion can be coordinated with one or two robots
• Load position can be programmed in 30-degree increments
• Ergonomic loading and programming heights
• MotoMount fixture mounting system

Dual headstock/tailstock ferris-wheel positioners

• Medium- to high-volume, medium- to high-product mix production
• Operator safely loads/unloads parts from outside robot's work envelope
• Space-saving design for parts three meters or longer (five-meter spans on most models)
• Servo control with absolute encoder feedback provides infinite part positioning location and coordinated motion during welding; part joints are kept in gravity-neutral welding plane
• Coordinated motion software is standard with postioner
• Metal arc screen divider creates barrier; safeguards operator from arc flash
• Two different design configurations:
  • Patented single-motor drive: Economical design requires fewer parts and uses single motor to operate all three axes; operator load station locks into position
  • Three-motor drive with patented “X-beam”: Each axis is driven independently; cycle time can be reduced by positioning part while sweeping; and operator station can be repositioned while robot is welding
• Tailstock options: slip rings for fixture signals and high-volume (3/4 in.) air lines

Headstock/tailstock positioners

• Available as individual headstocks or combined with MotoMount
• Compact design allows MH units to be easily integrated into othermachines or multi-axis positioners
• MH units can be mounted at an angle or as a rotary table
• Units have conservative torque rating and payload increases with tailstock (Contact Motoman for specification details)
• Multiple stations can be combined with a single robot controller or with a multiple robot controller
• Motion can be coordinated with the robot for welding contoured parts

Drop-center and tilt-rotate positioners

• Multi-axis positioners provide added application flexibility.
• Many provide two axes, allowing most welding to be done in the optimum position, thereby increasing travel speeds.
• Motoman software supports the coodination of both axes with robot motion.

Compare drop-center and tilt-rotate

MDC – Drop-Center Positioner

• Suited to very heavy frame components
• Framework supports counterweights for parts with off-center CG
• Thru-hole in faceplate for utilities

MH1500-450 TR – Tilt-Rotate Positioner

• Suited to construction equipment subassemblies
• Offset design allows open access for part load/unload
• Standard MH modules can be reconfigured with different
mounting structure

MotoPos – Tilt-Rotate Positioner

• n Suited to automotive assemblies such as seats or manifolds
• Very low-profile design provides ergonomic load heights
• Optional slip rings to deliver fixture utilities through the faceplat

Fixture mounting system

• Motomount™ – Reduces cost by eliminating machined bases, spanners and precision tailstocks (units bolt to framework or floor)
• Eliminates need for precision HS/TS alignment (allows up to two degrees of misalignment)
• Reduces tooling costs due to lower-precision mounting holes (can weld tailstock shaft to the fixture)
• Easy and quick fixture changeover
• Scalable to different sizes: 450 kg and 3,000 kg
• Improves tooling repeatiblity

Traditional Mouting System Vs. Motomount™

Transporters

• Moving the robot greatly increases the working range and application flexiblity.
• Motoman provides rotary transporters for robots in overhead- or floor-mounted configurations (MotoSweep-O, -F).
• Linear transporters are also available (MotoRail) in wall- or floor-mounted configurations. Both are available in heavy-duty configurations for large-payload robots. Multi-axis gantries are also available.
