With the development of science and technology, more and more industries need to use laser pointer diameter gauges, such as wire and cable, metal processing industry, rolling mills, laboratories, rubber industry, plastics industry and so on. The single-axis diameter gauge is a small desktop outer diameter testing equipment that can measure the outer diameter quickly, without damage, and accurately. It can be used in the production site or in the laboratory. It can also meet a variety of measurement requirements, such as outer diameter. , Width, thickness, position, etc.
The details that should be paid attention to to ensure the accuracy of laser diameter gauge measurement data. The outer diameter of the round rolled material has certain requirements for accuracy. At present, the manual card amount can reach the detection accuracy of 0.02mm. When it is tested online, the measurement accuracy will not be lower than this accuracy, not to mention the online detection is affected by human factors Small, but also more suitable for high-precision detection in large quantities.
At present, the measurement accuracy of the diameter gauge can reach 0.01mm, which fully meets the testing needs of products such as wires and cables. Although its own accuracy is high, some small details of use still require attention.
1. Installation orientation. The measurement area is vertically distributed with the cable under test to achieve high-precision measurement. The greater the deviation, the lower the detection accuracy. When the moving or touching caliper is shifted, it needs to be adjusted in time to make it as vertical as possible to the measured object.
2. Measuring area. Diameter gauges all have a parallel light field of view. Although they can be measured as long as they are in the parallel light area, they cannot be placed at the edge of the parallel light field of view, because the rolled material has a certain jitter during production. If you move out of the measurement area, you cannot measure accurately. Therefore, if the measured object passes through the center of the parallel light field of view as much as possible, this deviation is also acceptable. Adjusting the height of the pulley and the height of the bracket can adjust its position.
3. The lens is clean. As a precision optical device, the light transmission area of the lens is blocked by dust, etc., which blue laser pointer will affect the accuracy. Although the use of high-brightness light sources and calculation methods has greatly reduced the impact of dust on it, too much dust needs to be cleaned regularly. Use soft cloth or Wipe the lens with a paper towel, and also pay attention to protect the probe to avoid scratches, and replace the lens in time if it appears.
The single-axis diameter gauge measures the outer diameter with high precision, but in order not to lose accuracy, some details need to be paid attention to. Generally speaking, the diameter gauge requires very simple maintenance and very little work.
