Dimensional Checking Fixtures Specialists
Front bumper assembly
Bumper checking fixtures requirements can be very variable: from CMM fixtures fastening the part only by its RPS (fixation points), to cubing checking fixtures, simulating the part vehicle environment and controlling its deformation by Go/No Go gauges and dial indicator.
Front bumper trims
Checking fixtures for bumper trims composed of a single injected part – with or without emblem – or of several injected parts.
The number plate is one of the most visible parts of the car. Though quite simple, it is important to make sure that its fixations and shape are correct, to make sure that its fitting on the car will be perfect.
Engine bracket mount
This type of checking fixture usually enables to make a full check of the part. In order to be able to control all the necessary part features, more than one control station will be necessary in order to align the part by using different datums.
Depending on the design of the bumper assembly, the bumper central grille may be trapezium or rectangle-shaped. In both cases, a proper central grille checking fixture must reproduce its clipping system and vehicle environment.
Control of the headlamp washer functionality and main components: fixation points, water inlet and outlet systems.
Checking spoilers is very complex: these parts are highly deformable and composed of a huge number of clips, cross-shaped pins and fixation holes. Consequently, to produce a spoiler checking fixture that will be able to control properly this part, we must take into account all its specificities when designing, manufacturing and adjusting it.
As any part made of welded and bent components, it is essential to control the following features on exhaust line assemblies: position of the components welded to the main structure, location of holes, deformation of critical areas and position of bent sections. All these controls can be done either by Go/No Go or by dial indicator.
Scuttle grilles may consist of a single part assembly, or of two non-symetrical parts. Checking fixtures for scuttle grilles may control the fixations of the part, their fitting in the car environment and their fitting against the windshield.
Most of the car parts are controlled in their vehicle position. Yet, we usually recommend to control wheel arches upside down, thus making sure that they will not be deformed during their control.
As lateral grilles only have an ornamental function on the front panel, their shape can vary strongly from one version of car to the other. This also means that their specificities and fixations will also be affected by their aesthetic design. All these considerations must be taken into account when producing checking fixtures for lateral grilles.
As for any part composed of welded components, it is important to control the position of all the holes and components forming the catalytic converter. We can propose you a wide range of solutions, from checking fixtures with simple Go/No Go controls, to automated checking fixtures connected to a data acquisition system and enabling to measure 100% of the production.
Lateral brackets define the positionning of the bumper on the vehicle. Consequently, controlling the areas fitting with the bumper and the position of its fixation holes is basic to ensure a proper assembly on the bumper.
Checking fixtures for emblems, either as single parts, or as components of a front bumper trim.
For this type of parts, you must check that all the holes positions are OK for a proper fitting of the part on the car. In order to prevent collisions during the mounting process, you will also need to check the part outline to make sure that it is within tolerances.
As foglamp trims are part of the visible components of the car, its aspect and shape are of paramount importance. Consequently, the fixture controlling this type of part must be able to guarantee its dimensional conformity without damaging scraping it or tearing it, thus protecting its finishing.
