The invention relates to a measuring device and a measuring method of symmetry degrees of water through shaft through holes. The measuring device comprises a connecting block, a locating shaft and a measuring shaft, wherein the locating shaft and the measuring shaft are fixed on the connecting block side by side. The locating shaft is used for penetrating a through hole of a water through shaft to locate the water through shaft. A gap with the size which is not more than 2 mm is arranged between the measuring shaft and the water through shaft, wherein the water through shaft is installed on the locating shaft. According to the measuring method, a feeler gauge is used for measuring the gap between the water through shaft and the measuring shaft to indirectly measure the symmetry degrees of the water through shaft through holes. The measuring device and the measuring method of symmetry degrees of the water through shaft through holes are simple in structure, low in cost, high in efficiency, high in practical applicability and economical efficiency. The measuring device and the measuring method of symmetry degrees of the water through shaft through holes are suitable for measurement of the symmetry degrees of any shafts and the through holes and can be widely applied in the field of metallurgical machinery manufacturing.
Description
technical field [0001] The invention relates to the field of metallurgical machinery manufacturing, in particular, the invention relates to a measuring device and a measuring method for the symmetry of a water-through-axis through hole. Background technique [0002] The water shaft is widely used in the cooling system of metallurgical machinery. For example, the water shaft of the tension leveler is mainly used for the water cooling and positioning of the rollers in the tension leveler. In production, we often encounter the processing and maintenance tasks of the water shaft. During processing or maintenance, we usually use a combination of visual inspection and a vernier caliper to measure the symmetry between the water shaft and the through hole. The measurement can only be done by measuring the gap between the inner wall of the through hole and the outer circle of the water shaft. The difference, and the measurement reference selected during the measurement will change, ...
