Gauge blocks, as a precise measuring tool, are widely used in various industrial fields. They are not only used for
calibrating size references, but also for transmitting and measuring sizes. The classification of gauge blocks is diverse,
and based on their shapes and usage characteristics, they can be divided into different types.
Today, we will delve into the classification, usage methods of gauge blocks.
I. The definition of a measuring block
Gauge blocks, as a kind of precise measuring tool, play a significant role in the production process and quality control.
They are usually composed of a group of reference blocks with specific dimensions, which are precisely manufactured
and calibrated. These reference blocks are used to measure the size, shape, and position parameters of the workpiece.
The design of gauge blocks is exquisite, the material is uniform, and they have stable physical properties,
which can provide high-precision measurement results and ensure the quality control in the production process.
Gauge blocks, also known as block gauges, are important dimension control tools in the manufacturing industry.
They play a crucial role in transferring standard lengths to the dimensions of parts, and are also the core benchmark
for length measurement. In the field of technical measurement, gauge blocks are often used to calibrate other measuring
tools or serve as reference points for standard dimensions.
In short, the gauge block is like an impeccable "standard ruler". It not only ensures the reliability of measuring tools,
but also provides a solid foundation for the high precision of product processing. For every engineer, mastering
the correct usage methods and classification knowledge of gauge blocks is an important part of improving detection skills.
II. The shape and size of the gauge blocks
It is usually made of high-hardness, wear-resistant and stable bearing steel, and takes on a rectangular shape.
The measurement surface of the gauge block is finely ground and polished to ensure its parallel plane is smooth and flat,
while the non-measurement surface serves as an auxiliary function. Such a design enables the gauge block to play
a crucial role in manufacturing, helping to accurately control product dimensions.
The cross-sectional dimensions of the gauge blocks vary depending on their basic length:
For gauge blocks with a basic size ranging from 0.5 to 10mm, their cross-sectional dimensions are 30mmx9mm.
The measuring blocks with basic dimensions ranging from 10mm to 1000mm have a cross-sectional size of
35mmx9mm.
III. The flexible combination of complete sets of measuring blocks and the sizes of the blocks
In many practical measurement scenarios, a single gauge block often fails to meet all the requirements.
Therefore, the design of a complete set of gauge blocks becomes particularly crucial. These gauge blocks
are meticulously combined based on specific dimensions, and each set is neatly stored in a dedicated box,
making it convenient to carry around and use efficiently.
Single-sized gauge blocks are unable to meet diverse measurement requirements.
However, by flexibly combining gauge blocks of different sizes, a set of gauge blocks can easily fulfill various size
measurement needs. This combination method not only significantly improves the measurement efficiency but also
greatly expands the application scope of gauge blocks.
The design of the complete set of measuring blocks follows strict size grouping regulations, which include multiple size
blocks to meet diverse measurement requirements. For instance, a commonly used set of measuring blocks may contain
blocks ranging from as small as 0.5mm to as large as several tens of millimeters or even hundreds of millimeters.
Each block's size has been meticulously calculated to ensure complete coverage of the minimum intervals
to the maximum range when combined.
