CHECK OUR EXAMPLES OF CHECKING FIXTURES

Checking fixture for roof

Go/No Go checking fixture

  • Aluminium founding basis
  • Fixation of the part on its RPS (fixation points) by clamps
  • Control of the shape of the lower area of the part by blocks with a gap controlled by Go/No Go pin
  • Control of the shape of the upper area of the part by foldable blocks with a gap controlled by Go/No Go pin
  • Control of the location of the holes of the part by control pins.
  • Possibility of measuring the part by CMM machine.

Description

Several options of control - varying in terms of complexity, control method and budget - are available to control the largest parts of the car: as much checking fixtures with Go/No Go controls and/or dial indicator control points as solutions of control by artificial vision, like CAPTOR-R. The checking fixture presented in the example above could have been completed by control points by dial indicator, in order to provide a complete check of the part while getting measurement values for SPC studies.

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

To get specific measurement values on such fixtures, several options are available:
  • if the fixture is equipped with control points by dial indicator, the measurement process can be automated by using CAPTOR-S and CAPTOR-C systems.
  • if looking for a solution quicker than a measurement by CMM machine but providing more information than a 1D measurement, CAPTOR-R can be an interesting alternative enabling to check a wide range of characteristics of the part: its shape and dimensions, the location of its holes, etc.
