The role of the lamp head gauge, why do you make the lamp head gauge?

To understand these two questions, we first need to understand what is a gauge? Gauge, a type of measuring tool, the gauge itself has an accurate size and shape of the entity, such as cones, cylinders, block plates, rulers and threaded parts. In addition, the rubric is also an authenticity evaluation tool, which is a set of standards for evaluating or grading students' tests, growth record bags or performance, and it is also an effective teaching tool and an important bridge between teaching and evaluation.

Generally speaking, it is a kind of mold that can be measured, such as you are a factory, the production of lamp head, but the size of the lamp head is standard, with a ruler or vernier caliper for measurement, the error will be very large, and it is not convenient, at this time if there is a direct set of lamp head can know whether the size of the lamp head meets the standard measuring tool can save a lot of time and manpower, this is the biggest role of the lamp head gauge.

Just like the type of lamp head, the lamp head gauge is also divided into E (Edison) series screw lamp head gauge, B series bayonet lamp head gauge, BA series bayonet lamp head gauge, G series pin lamp head gauge, Fa series cylindrical pin gauge and other lamp head gauges, there are as many lamp head gauges as there are lamp heads.

In the international standard, IEC60061-1 is the standard of lamp head size, these lamp heads usually start with 7004 as a mark, if it is a manufacturer of lamp holders, the lamp head produced needs to be produced according to the size of this standard; IEC60061-2 is the standard for lampholder sizes, starting with 7005. IEC60061-3 is a standard for gauge sizes, these gauges usually start with 7006 as the model, and the lamp head holder gauge is an important gage used to detect whether the lamp head or lamp holder meets the specifications and requirements.

The hardness of the gauge is also required, GB and IEC in the hardness requirements for the gauge is HRC=58~65, and need to do anti-rust treatment, generally a gauge can be used for several years or even longer, if the accuracy drops, you can find a measuring institution to measure, to ensure the accuracy of the measurement.
