Shandong fortunes meter Precision Machinery Co., Ltd. is a business meter based production and processing enterprises, the company is located in Jining, Shandong Province, registered capital of 5 million yuan, mainly engaged in pneumatic-meter buoy, Chinese OSD electron column volume instrument, electronic pneumatic measuring instrument, pneumatic measuring instrument display screen, measuring gas inside and outside the school, the seizure of non-standard, thin-walled cylinder liners measuring devices and other products. 1, before use, should be checked carefully; first to check the drawings, look at this gauge is not consistent with the requirements of the inspection dimensions and tolerances, in order to avoid errors, causing a large number of waste. At the same time there is no gauge to check the amount certified by marks or other evidence; whether there is rust, scratches and burrs also check the gauge on the work surface; because these defects are prone to test surface deterioration, particularly tolerance level and more prominent surface roughness higher non-ferrous metal workpiece. Also check the gauge probe is securely coupled with the handle and, finally, check the workpiece to be tested parts (especially the hole) whether there are glitches, bumps, scratches and other defects. 2, and then with a clean fine cotton or soft cloth to gauge work surface clean, coated with a thin layer of oil to allow the work surface to reduce wear. 3, which is sure to want to identify through the end? Which is the only side? Make no mistake. 4, when used, the gauge of the correct method of operation can be summarized as "light", "positive", "cold", "full" before. Light: When using the gauge is to gently, safe and reliable; not arbitrarily throwing, do not collide with the workpiece, and then to put the stability test; when the test light should light truck plug, do not be rude and hard. Positive: that when a gauge inspection location must put positive, not skewed, otherwise the test results are not reliable, there is a lot of errors. Cold: that is, when the subject of the workpiece and consistent temperature gauge to be tested, and not be able just finished processing the workpiece also heat test; precision parts and gauges should be isothermal, before measurement. Full: is the amount of regulatory inspection work which must be comprehensive in order to get accurate and reliable test results through the end of the plug on the entire length of the hole to test, but also in two or three axial planes examination; plug only side to as tested at both ends of the hole through the side of the caliper and the end stop, should be about the axis along the axis and at least four locations for testing. 5, if the plug is stuck in the workpiece bore, can not beat an ordinary hammer, wrench twist or fall hard hit, otherwise it would damage the work surface plug. Then use the wood, copper, aluminum hammer or fitter tools (such as rugulosa or pushers), but also in the end face of the plug piece of wood or copper pads to protect, and then forced to pull out or launch. After, when necessary, the outer surface of the workpiece heated slightly in the plug pulled out. 6, when the workpiece clamping on the machine is still running, not gauges to test. 7. Do a gauge to test the surface roughness and dirty workpieces. 8 gauge through the end of each qualifying through the workpiece, the measurement surface often wear, therefore, gauge the need for regular checks. Ensure accuracy. Workload regulation, when plug through the end approaches or exceeds its minimum limit, calipers (ring) through the end approaches or exceeds its maximum size, the workpiece gauge should be changed to acceptance gauge to use, when acceptance gauge approaching or exceeding wear limit, should be scrapped immediately, discontinue use. 9, the use of smooth limit gauge test piece, such as determination of dispute, it should use the amount of regulatory inspection following dimensions: through the end piece should be equal or close to the maximum physical size (ie, the minimum limit of the hole size, the maximum limit size axis); end stop should be equal or close to the minimum physical dimensions of the workpiece (ie, the maximum limit size hole, the axis of the minimum limit of size).
