Description

Technical Field

[0001] The utility model relates to the technical field of gap measuring devices, in particular to a gap measuring device for automobile sheet metal. Background Art

[0002] The Automotive Sheet Metal Gap Measuring Device is a tool used to accurately measure the gap between automotive sheet metal parts. This device plays a vital role in automotive repair, body restoration and manufacturing processes, helping technicians accurately assess the relative position of sheet metal parts to ensure the quality of repair or manufacturing.

[0003] Common automotive sheet metal gap measuring devices generally measure the gap through a ruler, and install a pointer on the surface of the ruler. The pointer is driven by a threaded rod to move along the surface of the ruler. After the pointer moves to the side of the gap, the width of the gap can be measured. However, since the gap between automotive sheet metals is generally not more than 5 mm, when using a ruler for measurement, the density of the scale lines is relatively concentrated, resulting in the staff not being able to see the scale value pointed to by the pointer clearly. At the same time, since the pointer is moved by the threaded rod, when the amplitude of the threaded rod rotation is large, the movement distance of the pointer will also increase, and it is not easy to align the pointer with the edge of the sheet metal gap, resulting in inaccurate measurement of the sheet metal gap by the measuring device.
