Marble inspection platform

Marble inspection platform is also called granite platform. Specification: do not exceed 3000mm × 5000mm is applicable to the datum plane for various inspection and working accuracy measurement, and is used for the mechanical inspection and measurement datum of machine tools; Check the dimensional accuracy or shape deviation of parts, and make detailed marking and marking, etc

the marble inspection platform is strictly in accordance with the GB / T 8601.2001, JC / T 79-2001 standard. The marble inspection platform is used for various inspection work, such as the datum plane for detailed measurement, the inspection and measurement of various machine tools, checking the dimensional accuracy and line position deviation of parts, and making fine scribed lines. The marble inspection platform is a worktable that can not be missing for scribe, measurement, riveting welding and tooling processes

the marble inspection platform can also be used as a mechanical test bench. It is applicable to various inspection work, the datum plane for precision measurement, the mechanical inspection and measurement datum of machine tools, and the dimensional accuracy or behavior deviation of parts

marble inspection platform is a fine reference measuring tool made of naturally growing stone materials. It is an ideal reference plane for the inspection of instruments, fine tools and mechanical parts. Especially for the measurement with appropriate accuracy, the cast iron plate is dwarfed by its excellent product quality

the standard inspection tool of marble inspection platform is electronic level, but this instrument is expensive and few customers can equip it. Then, it is tested with dial indicator and dragged with magnetic gauge base; Then there is the laser rangefinder, which is a detection method invented by one of our customers, with high accuracy; Some customers use three coordinates to check the flatness of marble inspection platform, which is actually a wrong practice. Research has proved that three coordinates are only suitable for testing marble inspection platform products with flatness and parallelism and double-sided accuracy; Class 00 marble detection platform needs to be tested in a constant temperature chamber, otherwise its accuracy error will be affected

placement and adjustment of marble inspection platform before verification, change the height of three supporting points, and use a level gauge to roughly adjust the marble inspection platform to the level, so that the load of the flat plate is evenly distributed on each supporting point. The supporting points added by the large flat plate shall be padded stably and the horizontal plane shall not be damaged When checking with a level, the marble inspection platform itself is the measurement base surface, and its placement should be stable; When the autocollimator is used for verification, the instrument and the flat plate are not on the same rigid body, and the firmness of the instrument support is particularly important. Therefore, the verification regulation requires that the verification site should be firm and stable, and the verification site should avoid vibration. This is because: the factory often places the small flat plate on the bench or table, which is firm and has poor stability. The movement of verification personnel near the plate and the movement of verification tools on the plate will produce different gravity, which will change the spatial position of the plate and the measurement results are not good. Therefore, when verifying this kind of flat plate, the flat plate should be moved to a firm and stable site to avoid the influence of gravity change on the measurement results

for the movement of the verification personnel on the large marble inspection platform, the stability of the verification site should be considered and the influence of gravity change should be paid attention to For 400mm × For small plates below 400mm, especially rock plates, the weight of the plate is light, while the weight of the verification tool (level gauge or mirror and bridge plate) is heavy. When they are placed in different positions, the load of the three fulcrum of the plate changes unevenly, resulting in contact deformation between the plate and the support. In addition to considering the stability of the verification location, attention should also be paid to the weight of the verification tool, When necessary, auxiliary support shall be added to enhance the firmness of flat plate placement and the accuracy protection of marble inspection platform
