CHECK OUR EXAMPLES OF CHECKING FIXTURES

Rear-view mirror foot checking fixture

Checking fixture for triangle-shaped mirror foot

  • Aluminium base plate
  • Fastening of the part by its vehicle fixation points
  • Control of the part shape by a block simulating the outline of the part and a Go/No Go pin.
  • Control of the part surface deviation by dial indicator control points
  • Control of the part tourillion by a special Go/No Go gauge controlling the shape of the tourillion and the position of its fixation holes

Checking fixture for cone-shaped mirror foot

  • Aluminium base plate
  • Simulation of the fitting of the part on the vehicle
  • Control of the dimensions of the areas fitting with the mirror assembly by sliding pins

CMM fixture

  • Aluminium base plate
  • Fastening of the part by its vehicle fixation points
  • Control of the part by CMM machine

Description

The problems that may occurr when producing mirror feet are variable, depending on the material used and of the shape of the part: deformation of the part surface, unproper location of its fixation points, etc. To make sure that all the potential deformations of the part will be detected, we recommend to use a fixture simulating as much as possible the vehicle conditions of fitting of the part, as much for its fixation points as for its vehicle environment. A CMM version of this fixture may, however, be helpful for the measurement by CMM machine of the first injected parts of your series.

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.
