CHECK OUR EXAMPLES OF CHECKING FIXTURES

Rear-view mirror Housing

Control of the fixation holes location

  • Fastening of the part on its pivot shaft by a clamp and a centring pin
  • Control of the area of the housing visible in the mirror assembly by a fixed block and a Go/No Go pin
  • Control of the location of the housing fixation holes by sliding pins
  • Control of the deformation of the outline by dial indicator

Control of the fitting of the housing with the skull cap

  • Fastening of the part on its fixation holes by centring pins and a clamp
  • Control of the fitting areas of the housing and the skull cap by dial indicator
  • Control of the outline of the housing by dial indicator

Complete checking fixture

  • Fastening of the part on several fixation holes by centring pins and clamps
  • Control of the area of the housing visible in the mirror assembly by a fixed block and a Go/No Go pin
  • Control of the location of the part fixation holes by sliding pins
  • Control of the part outline by dial indicator

Description

Rear-view mirror housings can either be controlled as single parts, or as two separated parts (housing bracket and housing), depending on the design of the rear-view mirror. The critical aspects usually controlled in this type of part are: the outline deformation, the fitting with the mirror assembly components, and the location and/or diameter of the part fixation holes. These features can be controlled either by Go/No Go controls, or by dial indicators.

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

Depending on the requirements of the customer, the number of dial indicator control points on housing checking fixtures can be quite high. In that case, automating the measurement process in order to improve traceability, prevent measurement faults and get a good follow-up of the measurement is crucial; solutions like CAPTOR-S, and its complement CAPTOR-C can thus easily be justified for the time and cost they enable to save.
