The riser adjusted robot mounting height while preserving the relationship between its upper and lower mounting planes.
The customer’s challenge
Welding distortion made the faces nonparallel, tilting the installed robot and affecting positioning.
Material and fabrication route
3.0 mm welded Q235 steel.
Process route: Cutting → welding → stress relief → CNC machining of both faces → powder coating → parallelism inspection.
Manufacturing changes
Post-weld stress relief and finish machining established parallel mounting planes. Adjustment holes supported installation.
Engineering analysis
The riser changed mounting height without allowing the robot’s upper reference plane to tilt relative to its base. Post-weld treatment and machining addressed that relationship directly. The parallelism figure is distinct from the load result and height range: each answers a different integration question. A comparable riser should identify both mating planes and the actual installation load rather than only its outside envelope.
Inspection and project results
Parallelism reached ≤0.05 mm/m and the robot installed level without the prior alignment problem.
| Project measurement or production detail | Recorded value |
|---|---|
| Face parallelism | ≤0.05 mm/m |
| Height variants | 100–500 mm |
| Load test | ≥200 kg |
These figures describe the project configuration and production scope above. Dimensional, material and production details are identified separately from performance tests. For a new order, the inspection method and acceptance criteria should be agreed against the released drawings.
Planning a similar OEM component
A useful RFQ for this application should make the following interfaces and acceptance requirements clear:
- Robot and floor mounting patterns.
- Upper and lower datum planes.
- Height and load configuration.
- Parallelism and installed-level requirements.
Include the current drawing revision, mating-component information, quantities and required delivery sequence. Identifying unresolved requirements at quotation stage helps distinguish fabrication work from the equipment-level checks that the project needs.
