AI Technical Summary

Technical Problem

Existing ultrasonic flaw detection structures struggle to achieve uniform downward pressure and stable coupling when facing continuously undulating surfaces of plates, resulting in poor flaw detection performance and low efficiency.

Method used

An adaptive structure based on a combination of dual-cylinder springs and hinges is adopted. Uniform downward pressure is provided by multi-axis cylinders on both sides, and floating coupling is achieved through the hinge of the four-sided frame with the pressure frame and the flaw detection adaptive structure to adapt to the undulations of the plate surface.

Benefits of technology

This achieves stable and uniform downward pressure on a continuously warped plate surface, improving the efficiency and effectiveness of flaw detection and ensuring the stability and accuracy of the flaw detection process.

Abstract

The utility model discloses a self-adaptive structure for ultrasonic flaw detection based on a double-cylinder combined spring and a hinge, which comprises a fixed mounting seat (1), a group of multi-shaft cylinders (2) are respectively fixed on two sides of the fixed mounting seat (1), the telescopic ends of the multi-shaft cylinders (2) are arranged downwards, and cylinder joints of the multi-shaft cylinders (2) are respectively connected with a left lower pressing frame (3) and a right lower pressing frame (4) on the corresponding sides; tension springs (5) are connected between the fixed mounting seat (1) and the left lower pressing frame (3) and between the fixed mounting seat (1) and the right lower pressing frame (4), a four-side frame (6) is arranged between the left lower pressing frame (3) and the right lower pressing frame (4), hole parts of the left lower pressing frame and the right lower pressing frame are hinged with a shaft part of the four-side frame (6), and the hole part of the four-side frame (6) is hinged with a shaft part of a self-adaption device (7) for flaw detection. The self-adaption device has the advantages that uniform downward pressure is provided for the self-adaption device for flaw detection, the stability of coupling of the self-adaption device for flaw detection and the surface of a plate is ensured, and the working efficiency and the flaw detection effect are improved.
