| What is the Gap Gun? |
 |
The
Gap Gun is a handheld laser gage that checks product build geometry in
production or rebuild
facilities. It provides repeatable measurements of gap, flush
(gap and step, or gap and mismatch), area, radius, angle, protrusion plus other
parameters, on painted, unpainted, curved and square cut surfaces. The Gap
Gun measures by laser triangulation, an optical technique that allows
accurate measurements to be made without touching the surface to be
measured.
|
|
|
Why invest in a Gap Gun? |
|
The Gap Gun offers the following advantages over
other gap and flush (step or mismatch) measurement equipment.
|
Accuracy and Repeatability.
The Gap Gun has repeatability better than 20
microns
(0.0008”). This is a great improvement over manual measurement techniques
such as calipers, slip gauges, or taper gauges which rely on operator
technique. |
|
Simple
and quick to use.
Once the process has been
set up, the
measurement procedure consists of merely selecting a software tool, moving
the gun into position and pulling the trigger. |
|
Non-contact.
The Gap Gun never touches the part being measured and
can not damage it. |
|
Ergonomic. The Gap Gun is
small, lightweight and well balanced. |
|
|
 |
|
Allows easy access to measurement results.
Results are displayed on the Gap Gun’s screen.
In addition the measurements are logged in a number of formats, including
comma separated variable (*.csv), Microsoft Excel and Access and DMIS. The
results can be made immediately available over a computer network. |
|
Efficiency. Data such as gap and flush are
both measured and reported simultaneously. Measurements
can often be made in 25% or less of the time previously required. |
|
Wireless. The Gap Gun is
available in a wireless configuration with a range of 50 meters (150 ft).
The user is free to move around the part while measurement data is
logged to the controller and network, if required. |
|
Statistical Process Control compatible.
The Gap Gun may optionally be supplied with QDA
software which provides Statistical Process Control (SPC) support.
Alternatively, the system may be integrated with your existing SPC
software. |

What does the Gap Gun
System consist of? |
|
|
|
Gap Gun
components include the handheld unit connected by cable to a controller and
LCD display, Gap Gun software and a transport case or rolling cart. |
|
 |
|
Wireless Option:
The ergonomically designed Gap Gun is connected to small, light weight
power pack that is carried over the operators shoulder. The pack also
contains a wireless transmitter/receiver. This transmitter/receiver has a
range of 50 meters (150 feet). The wireless version can also be provided
with a notebook PC in place of the standard controller for complete
portability. |
|
|
|
The Controlling Computer. A high
quality, custom configured computer completes the Gap Gun package. Data is
transmitted from the Gap Gun to the computer for processing and storage.
The controlling computer may be connected to your computer
network, thereby making measurement data available for real-time review. |
|
|
|
What is the procedure for
making measurements with the Gap Gun? |
-
Pull trigger on the Gap Gun which turns the laser on.
-
Move the Gap Gun toward the feature that you wish to measure as indicated
in by the arrow in the diagram below. The operator aligns
the laser stripe to the area where the gap should be measured.
 |
 |
-
As
you move into measuring range, green LEDs
illuminate the surface. Hold the Gap Gun still to allow it to make measurements. The
measurements take no more than a couple of seconds to complete.
-
When the measurements are completed the results are
displayed on the Gap Gun’s screen. The results are also displayed on the screen
of the computer and stored in a database.
|
|
What setup procedure
is required for the Gap Gun? |
Measurement sessions are preprogrammed by selecting an appropriate
software tool for the particular feature being measured. A library
of standard tools is available to measure common shapes such as:
|
square edge parts |
|
curved edge parts |
|
square/curve combinations |
|
right angle gaps |
|
closest point between surfaces |
|
radius of curvature |
|
rivet height |
|
|
|
|
 |
Tools can be modified to accommodate parts of
different geometries of unusual surface texture.
After the tools are selected, they are stored in
a sequential measuring plan using operator assigned names for each tool. |
|
Where can the Gap Gun be used? |
Accurate measurements can be made on most
surfaces including all automotive paints, bare, polished and galvanized
metals, plastics, soft furnishings, and some chromes. Glass and
mirrored surfaces can be measured if they are coated with powder spray or
tape.
Difficult to access features may be
measured with the Gap Gun by detaching the measuring head from the body
and making use of the optional extension cable.
