Checking fixture for door pocket

Basic + CMM fixture

  • Aluminium base plate
  • Fixation of the part by centring pins and clamps on its RPS (fixation points)
  • Control of the mountability of the part on the fixture
  • Control of the upper area of the part by a simulation of the door environment by removable anodized aluminium blocks
  • The use of removable control blocks enables to get access to all the part for a complete measurement by CMM machine.


A series of characteristics that can  be controlled as much by Go/No Go controls as by dial indicators have to be checked on door pockets in order to ensure their proper fitting on the car doors.

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.
