Introduction

GapGun3 is a non-contact laser measurement device to check gaps and flushes. It contains both an integrated display and wireless data communication to a computer. GapGun3 can take accurate and repeatable measurements on curved surfaces to check gaps, flushes, radii, rivets etc.

The non-contact optical laser triangulation principle eliminates the danger of surface damage during the measurement process. With the improved 240 x 320 pixel color touch screen and ruggedized design, the GapGun3 is the ideal solution for many measurement tasks for it replaces complicated and expensive custom gauges, vernier calipers, depth gauges and taper gauges.

Applications

The GapGun handheld laser gauge is a quality assurance tool that checks product build geometry in production, maintenance and repair facilities.

Panel match, fit can be measured in many different stages and parts:

  • Body in white
  • Painted surfaces
  • Interior trim
  • Interior panels
  • Beads
  • Dents scratches

Concept

GapGun measures by laser triangulation, an optical technique that allows accurate measurements to be made without touching the surface to be measured. This provides repeatable measurements and more on painted, unpainted, curved and square cut surfaces.

  • Strong, fast and easy to use: The GAPGUN is small, light and ruggedly designed. It can take multiple measurements from most surface shapes up to ten times faster than other gauges.
  • No surface damage: Laser triangulation technology means the GAPGUN never touches your product, reducing the danger of scratches or dents and facilitating new types of measurement.
  • Robot compatible: The measurement head can be removed from the GAPGUN’s body and attached to a robot or co-ordinate measuring machine (CMM), ensuring consistent measurements and providing a fully automated measurement solution.
  • True portability: You’re not tethered to a PC during testing. You can connect your GAPGUN to a laptop or other computer by 802.11 WiFi or Ethernet.
  • On-screen graphics: You can upload photographs on to the GAPGUN’s large, color touch screen, giving operators pictorial as well as written directions.
  • Full SPC: The GAPGUN’s Statistical Process Control system enables comprehensive planning, collection and analysis of measurement data.
  • Proven precision: Conforming to QS9000-MSA for a wide variety of complex measurement problems, the GAPGUN provides a dramatic improvement in Repeatability and Reproducibility (R&R).

Metrics

Many different metrics can be identified based on a few simple measurements.

  • Panel gap and flush in multiple configurations
  • Rivet protrusion
  • Radii
  • Angle measurement
  • Scratch and dent measurement
  • Sealant beads height and width
  • Burr
  • Chamfers
