Welding U-Type 100-300kg Double Axis Tilt Positioner ≤1arcmin for Robot Cells

Small U-Type Double Axis Tilt Welding Positioner for 100-300kg Fixtures

The GBS-02-U100 and U200 and U300 are compact 100-300kg double axis positioners built for robot cells where the part is light but the weld geometry is not simple. The U-shaped frame carries a table that tilts through 0-360° and rotates through 0-360°, so a small fabrication can be presented to the torch at the angle that gives the best penetration instead of being re-clamped by hand. Positioning accuracy is ≤1arcmin, table height is 800mm as standard, and the gear motor is available from 1kW to 3kW depending on how fast the cell must index. The unit runs on 220V or 380V 50/60Hz and is sealed to IP65 against spatter and grinding dust. Because the payload range starts at 100kg, this welding tilt turntable 0-360° fits cells that would be over-specified by a 500kg machine, while still sharing fixtures and programs with larger models in the same family.

Technical Specifications

Advantages for Small Cells

• Compact footprint: a small U-frame leaves room for the robot, the fence and the operator station in a cell of limited floor area.
• Two axes of adjustment: tilt and rotation together bring three or four sides of a part within one robot program.
• Repeatable clamping: quick-change plates keep fixture position stable, which protects the ≤1arcmin accuracy between batches.
• IP65 sealed drive: spatter and dust do not reach the gearbox or feedback, cutting unplanned stoppages.
• Family commonality: controls and interface match the larger GBS positioners, so operators learn one system.

Typical Applications

• Welding of small frames, brackets and handles
• Stainless steel kitchen and catering equipment
• Bicycle and motorcycle sub-frames
• Sheet metal enclosures and electrical cabinets
• Repair cells handling small mixed batches

Frequently Asked Questions

Q: Is a 100-300kg double axis positioner strong enough for a robot cell that also runs larger parts?
It is sized for 100-300kg of part plus fixture. If the same cell will also run heavier work, choose the 300kg model and confirm the fixture mass; the frame and drive are selected for the declared total, not the part alone.

Q: How does the welding tilt turntable 0-360° keep the torch angle constant?
Both axes are external axes of the robot, so the controller coordinates table motion with the torch path. The robot re-orients while the table turns, and the weld stays in the flat or horizontal position.

Q: Can the small table be fitted with a chuck or a custom plate?
Yes. T-slot plates, three-jaw chucks, vacuum plates and dedicated fixtures are available, and the table height can be adjusted for ergonomic loading.

Q: What is the lead time for an IP65 small welding positioner?
Standard models ship in 15-30 working days. Fixture plates and non-standard table heights add design and manufacturing time, confirmed at order.

Production and Support

Gongboshi Robot Technology has produced positioners and robot external axes in Shanghai since 2016, with over 100 engineers supporting aerospace, automotive, chemical and new-energy customers. Every IP65 small welding positioner is assembled, run in and load tested, and ships with a test record, wiring diagram and fixture interface drawing under a 12-month warranty with remote commissioning help.
