Rearlamp

Healamps and rearlamps are components particularly difficult to check: apart from their dimensional conformity, they must be able to stand the climate and vibration conditions they will exposed to during the car useful life. Consequently, we propose to our customers three types of fixtures for these parts: complete checking fixtures – for lamps assemblies -, test fixtures – to be used on test laboratories -, and sub-assemblies checking fixtures – for the lamps components.

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.

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

Headlamps and rearlamps fixture usually have a number of dial indicator points ranging between 6 to 12 points, which implies a relatively long cycle time. Using CAPTOR-S for this kind of fixtures helps reducing the risk of faulty measurements, the cycle time, and thus helps repaying on a shorter term the checking fixture.

Rearlamp complete fixture
  • Aluminium base plate
  • Simulation of the car fixations: sealing gasket, clips and fixation screws.
  • Simulation of the car environment: bumper, by fixed, foldable or removable blocks
  • Control of the part by dial indicators and Go/No Go pins
Sub-assemblies checking fixtures
  • These fixtures control the components composing a rearlamp – or headlamp -, that is the housing and lens of the part.
  • Optional: possibility of mounting the trunk and fender fixtures together, to check the proper fitting of both parts on the car.
Test fixtures

A series of checking fixtures must be produced to submit head and rearlamps to specific tests simulating their conditions of use during the car useful life. The list bellow presents the most common ones:

  • Photometry fixture: control of the correct absorption and transmission of light of the parts. This fixture is produced in black-anodised aluminium – to prevent any reflection while in use on the photometry bench -.
  • Rain and salt test fixture: control of the waterproofness of the part. This fixture is produced in stainless steel, and simulate the sealing gasket of the part, to stand its use in waterproofness tests – partial or complete submersion into water – and its contact with corrosive materials – salt -.
  • Temperature test fixture:  this fixture must be able to stand the temperature tests carried out on the part, usually in a temperature range between -40º and +80º.
  • Vibration fixture: this fixture, mounted on a vibration test bench, submits the part to a series of vibrations simulating the use of the lamps in the vehicle in motion. The fixture simulates all the fixations and – if requested – the car environment, and must be submitted to a resonance test, to make sure that no vibration coming from the fixture will cause interferences during the test.
