Description

Wedge-shaped measuring device for determining gap dimensions on motor vehicles. The distance between body parts, for example the fender from the door, is called the gap dimension.

State of the art

To measure gap dimensions, a folding rule, a caliper or a ruler according to DIN ISO 10012-1 is usually used.

Well-known automobile manufacturers have produced so-called measuring plates with different thicknesses, e.g. Volkswagen AG, 38436 Wolfsburg, VAG part number: 3371. These measuring plates are inserted into the gap whose width is to be measured. If the appropriate measuring plate can be inserted with little effort, the gap size shown on the measuring plate is read.

Uneven gaps in the area of the body parts indicate distortion of the body or poorly manufactured body parts of motor vehicles.

Problem:

When measuring with a folding rule or ruler, it is not possible to determine the gap size precisely, as measurement errors arise due to parallax or, in the case of rounded edges, which are common in automobile construction, for example, it is not possible to measure the gap precisely.

When measuring with the caliper, the sharp-edged measuring jaws can cause scratches and damage to the paint layer. In addition, the caliper cannot be used in tight spaces due to its size and shape.

Solution:

The measuring wedge is inserted into the gap to determine the gap size. The depth of penetration of the measuring wedge is read directly from the scale attached to the measuring wedge. This scale indicates the depth of penetration of the measuring wedge into the gap in the unit of measurement, here in tenths of a millimeter.

Benefits achieved:

The invention makes it possible to measure gap dimensions in a simple manner. Due to the spread of the scale, a high degree of accuracy of the measurement result is achieved, in this case up to 1/10 millimeter.

This enables a quick check of the manufacturing quality in the area of gap dimensions during the manufacture of motor vehicles.

When checking motor vehicles after accidents, it is easy to determine whether the gap dimensions have changed. This can indicate serious damage to the bodywork.

In contrast to a caliper or folding rule, the measuring wedge usually stays in the gap to be measured due to its low weight. An assistant to hold the measuring device while taking photos for documentation purposes is not necessary. This means that the measured gap can easily be documented with a photo using one hand.

Further design
the invention

If there is material within the gap to be measured that prevents the measuring wedge from penetrating, such as a seal or bead, the tip of the measuring wedge is cut off so that it penetrates deep enough to allow the exact measurement to be read.

The scale is given in millimeters.

For the Anglo-American area, the information in

inch is provided.
