Automatic control for rivets

Riveting is a process used to join construction components made of the same or different materials permanently.

Many rivets are used in components for the aircraft industry. In aircraft assembly, riveting is a multi-step fastening process that requires strict adherence to quality and safety standards.

Fixation processes traditionally require human skills. Today, riveting is increasingly automated by robots that perform long processes from drilling, to milling and finally to riveting.

In the transport sector, reliable quality control plays a particularly important role. The condition and especially the sealing of the rivets are essential for safety. Defects may occur during the fixing process.

We combine high tech vision control systems with robotics and smart processing software. Considering the evolution of the aerospace industry, the automation of rivet setting and its associated quality control is key for the future.

Our customers need a solution for measuring rivet misalignment. Specifically, the depths of the countersinks after drilling and the flush measurement of the rivet must be checked.

In our new project, we are measuring rivet misalignment in relation to a panel. This project has two specific aspects: no physical play then accurate measurement of the assembly. To contribute to safety, our engineers have developed an automated solution for measuring countersink diameters and depth prior to fastener installation, as well as a solution for the automated measurement of rivet flush and squaring to the surface. Our 3D technology is used to check not only rivet conformity, but also the surface condition of the fuselage after assembly. Successful projects have already been completed with some of our customers.

Edixia’s new technologies ensure that the techniques and processes used for assembly are correctly implemented.

Our solution:

  • The measurement of countersink diameters (drilling and milling) and depth before the fasteners are installed.
  • Measuring the flush and squaring of the rivets with respect to the surface

Advantages:

  • Accuracy: approx. +/-18 µm
  • Online or manual measurement, fast and accurate to 1/100th second
  • Detection of cracks and surface corrosion
  • System can be integrated on any automated or mechanised line
  • Quality control
