Description

Technical Field

[0001] The present application relates to the field of rotor curvature measurement, and in particular to a heavy-duty rotor curvature disk dynamic measurement device. Background Art

[0002] During the operation of the equipment, the curvature of the rotor will change due to thermal stress, mechanical stress, manufacturing defects, abnormal operating conditions, etc. The change in the curvature of the rotor will affect the performance efficiency and safe operation of the equipment. Therefore, during the operation of the equipment, the curvature of the rotor needs to be measured regularly.

[0003] V-shaped iron is used for shaft inspection, correction, and marking. It can also be used to inspect the verticality and parallelism of workpieces, and for the inspection, marking, and setting of precision shaft parts and clamping in mechanical processing. It is mainly used to place circular workpieces such as shafts, sleeves, and discs in order to find and mark the center line. Generally, V-shaped blocks are a pair of two pieces, and the planes and V-shaped grooves of the two pieces are ground out in one installation. The parallelism and verticality errors of the dimensions of the precision V-shaped blocks are within 0.01 mm. The center line of the V-shaped groove must be within the symmetry plane of the V-shaped frame and parallel to the bottom surface. The errors of concentricity and parallelism are also within 0.01 mm, and the half-angle error of the V-shaped groove is within the range of ±30 to ±1. Precision V-shaped blocks can also be used for marking. V-shaped blocks with clamping bows can firmly clamp cylindrical workpieces on the V-shaped blocks and flip them to various positions for marking.

[0004] In the prior art, when measuring the curvature of a rotor, a method is usually adopted in which both ends of the rotor are supported on a V-shaped iron for measurement at room temperature. During measurement, the horizontality of the V-shaped iron itself should be ensured, and the allowable deviation is required to be less than 0.02 / 1000 mm.

[0005] However, when using the above measurement method to measure heavy rotors, due to the large mass of heavy rotors, in order to ensure accurate measurement, a V-shaped iron with high rigidity and large volume is required. The contact area between the rotor and the V-shaped iron is too large, resulting in excessive friction, making it impossible for the rotor to rotate. Utility Model Content
