1) Reduce the wear of inspection tools

The fundamental reason for the wear of inspection tools is the mutual friction between parts. Reducing this friction or improving the wear resistance of inspection tool parts is an effective way to reduce the wear rate of inspection tools and improve their effective lifespan

1. Reasonably select inspection tool materials

The wear resistance of materials is one of the main factors determining the wear rate of inspection tool parts, and the wear resistance of materials mainly depends on the type of material and the heat treatment state. In general, the hardness of commonly used inspection tool materials that require wear resistance should be improved through quenching or other heat treatment methods. The harder the material, the better its wear resistance.

2. Improve the surface quality of inspection tool parts

Firstly, it is necessary to improve the precision machining quality of the part surface. The finer the part processing, the smaller the surface roughness value, and the slower the wear rate, resulting in a longer service life. Secondly, efforts should be made to avoid softening of the surface material of the parts during the processing, in order to prevent a decrease in material wear resistance. For example, when grinding, if different process conditions are selected, grinding will occur, resulting in a decrease in the hardness of the surface material and greatly reducing the wear resistance of the parts. Moreover, scratches should be avoided as much as possible during the processing of parts. These subtle cracks will slowly expand and either corrode or crack when used frequently or in harsh environments.

3. Lubrication treatment

In production workshops, assembly workshops, especially welding workshops, there are usually dust or small particles that adhere to the surface of moving parts of the inspection tool. If the inspection tool is forcibly used, the particles will rub against the parts, causing surface damage to the parts. And lubricating media can play a role in cooling, cleaning, and preventing pollution on the friction pair. The detection pins, positioning pins, and other parts with relative motion of the inspection tool should be regularly lubricated with lubricating oil and rust proof oil to reduce friction coefficient and friction resistance between parts.

2) The structure of the inspection tool is firm and reliable

When designing inspection tools, it is necessary to fully consider the load situation in the stress area, and ensure that the weak parts have sufficient strength and stiffness, especially for load-bearing parts, which generally require reinforcement with ribs. The structure of the inspection tool is firm and reliable, which can withstand the impact of external loads to ensure its stability and reduce the risk of plastic deformation. We also need to avoid structural bloating caused by excessive intensity, as well as inconsistent layout and proportion of inspection tools.

3) Reasonable and standardized operation, in accordance with the articles of association

The accuracy of the inspection tool determines the quality of the product during mass production. It can be described as "a drop in the bucket leads to a thousand miles". During operation, it is necessary to follow the inspection tool specifications as a guide, and operate in an orderly manner following the steps of positioning first and then testing. Unauthorized disassembly and free assembly of components are not allowed. If parts need to be moved and adjusted, they must be measured in three coordinates to confirm that the results are qualified. More than 98% of the inspection tools are made of steel parts. If the service life of the moving parts is long and maintenance is improper, it can lead to the phenomenon of "jamming" of the moving parts. At this time, it is not possible to manually repair the inspection tools with hard objects such as hammers. If a malfunction occurs, it should be reported to specialized personnel for handling. Improper operation by the user may lead to deformation and fracture of the inspection tool parts, resulting in accuracy failure. On site personnel need to undergo certain training, wear relevant labor protection equipment, and operate in a standardized manner to reduce human damage to the inspection tools and ensure their good working condition.

4) Regular maintenance, periodic re inspection and verification

When the gauge is not in use, it needs to be moved to the designated area. Strictly implement regular maintenance and daily inspections, and carry out maintenance work to eliminate faults in their early stages. When the inspection tools are used for the specified time, accuracy verification must be carried out.
