Abstract

This utility model relates to the field of coupling processing technology, specifically a pressure testing device for couplings, including an operating table and a pressure testing component mounted on the operating table. This pressure testing device for couplings, through the cooperation of a feeding component and a transfer component, achieves automatic loading, transfer, and unloading of couplings, completely eliminating the inefficient traditional manual loading and unloading mode. It can meet the needs of large-scale testing, significantly improving production efficiency. The device also integrates a pressure testing component and a vision inspection component, enabling the completion of pressure performance testing and surface damage testing on the same equipment. This avoids the cumbersome process of switching equipment required in traditional testing, shortening the testing cycle. The vision inspection component can also adjust the angle and distance of the vision inspection head according to needs, and in conjunction with the rotating component, drives the rotating support to rotate the coupling, achieving all-round, blind-spot-free inspection of the coupling's surface, effectively avoiding missed inspections.
