Checking fixture for wheel arch reinforcement

Wheel arch reinforcement production fixture

  • Aluminium founding basis
  • Fastening of the part by clamps and support pins. Option: in case of control of the part after its hot-stamping and after its laser cutting, possibility of integrating to the fixture rectractable support pins, to make the fixture suitable for the two versions of part.
  • Control of the part shape and outline by a block - in resin or aluminium - with a gap and flush controlled by Go/No Go pin.
  • Control of the deformation of the part main critical areas by dial indicator.


In the example shown here, the fixture enables to control the final part, after its laser-cutting. Consequently, in that case the fixture fixation system can be fixed, as only one version of part is being controlled. To produce a fixture suitable to control the part after its hot-stamping and after its final cutting, the fixture will have to integrate retractable support pins - see examples on A-Pillar and B-Pillar pages -

Materials and tolerances

Our checking fixtures are produced in aluminium, the components submitted to wear-and-tear are produced in steel. Tolerances for RPS (fixation points) and dial indicator points: ±0.05mm. Tolerances for simulation blocks: ±0.1mm.

Documentation delivered

Minimum documentation: dimensional report of your checking fixture, 2D assembly drawing, assembly CAD.  Optional documentation: R&R report, user manual, stabilization certificate.

Cycle time and traceability

Integrating CAPTOR-S or CAPTOR-C system to this type of fixture enables to reduce the measurement cycle time by 70% and to improve the reliability of the measurement. These systems thus enable to the production process to be more reactive - quicker decision-making, possibility of measuring more parts -.
