Abstract
Description
Technical Field
[0001] This utility model relates to the field of inspection tool technology, and in particular to a spherical distribution plate height measuring device and measuring system. Background Technology
[0002] Spherical distributor plates are typically core components in hydraulic pumps and motors. Their surfaces are machined with a specific curvature spherical structure to dynamically engage with the rotor or swashplate, achieving precise distribution and sealing of high-pressure hydraulic fluid through the periodic opening and closing of oil passages. The machining precision of the spherical height determines the volumetric efficiency, operating noise, and service life of the hydraulic system.
[0003] Existing methods for measuring the height of spherical distribution disks typically employ the traditional three-coordinate measurement method. This involves scanning a circle on the bottom plane to obtain the bottom element, scanning six circles on the sphere to construct the spherical element, and then constructing a theoretical circle on the sphere parallel to the bottom plane. The distance between the constructed theoretical circle and the bottom plane is then measured. This measurement process is time-consuming and inefficient. Utility Model Content

The diameter of the positioning rod 3 is equal to the inner diameter of the spherical distribution plate 4 to be measured. The spherical surface 41 of the spherical distribution plate 4 to be measured is inserted downward into the positioning rod 3 until it contacts the positioning ring 2. The distance from the positioning ring 2 to the top surface 42 of the spherical distribution plate 4 to be measured is measured.
