Checking Fixtures for Rear-View Mirrors Assemblies

This video presents a checking fixture for a rear-view mirror assembly that simulates the area of the door where the support of the part is mounted.

This type of checking fixture is the ideal tool to check rear-view mirrors assemblies, because it enables, on the one hand, to simulate the real conditions of mountability of the part on the vehicle, and on the other hand, to carry out a full check of its shape.

Ideally, on a checking fixture for rear-view mirror, the gap and flush are checked with a dial indicator. The problem is that this type of control means to have to put foldable arms to hold the dial indicator during the control process; this is an efficient system, but it takes space, and adds weight to the final fixture.

This is why we have designed for this checking fixture a dial indicator checking system adapted on a mobile turret. This system is used, reset and stored in the same way as a standard dial indicator, but it has the great advantage to give an accurate control of the part without having a checking fixture too heavy, or too big.

Checking fixtures for mirrors also have the advantage to be able to have different checking systems adapted, such as:

• gap/flush by Go/No Go
• controls by dial indicator
• controls by dial indicator on a mobile system
• controls by data capturing probes, connected to a data collection unit.

The latter solution, as simple for the user as a dial indicator control, has the great advantage to reduce the measurement cycle time and save a lot of time, enabling thus to have a checking fixture more quickly profitable.
