Embodiment Construction

[0055] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0056] Such as Figure 1-3 The ultrasonic testing device for uranium-based alloy fuel pellets shown includes an eight-channel probe adjustment device, tail top assembly, drogue assembly, portal frame, compression spring, guide rail, base, motor, portal frame motor, and taper sleeve motor.

[0057] The eight-channel probe adjustment device includes a bottom plate 1 , a side plate 2 , a top plate 3 , a connector 4 and a probe hanger assembly 5 .

[0058] The bottom plate 1, side plate 2 and top plate 3 are used to fix the probe adjustment device and are made of 45# steel. The connector 4 and the probe hanger assembly 5 are made of 304 stainless steel because they need to be soaked in water for a long time.

[0059] The bottom plate 1, the side plate 2 and the top plate 3 are all elongated thin plates.

[0060] The bottom plate 1 inclu...

Abstract

The invention relates to the technical field of ultrasonic detection, and specifically discloses an ultrasonic detection device for uranium-based alloy fuel pellets. The ultrasonic detection device comprises an eight-channel probe adjusting device, a tail jacking assembly, a taper sleeve assembly, a portal frame, a pressure spring, a guide rail, a base, a motor, a portal frame motor and a taper sleeve motor. The eight-channel probe adjusting device, the tail jacking assembly and the taper sleeve assembly are all arranged on the guide rail, the tail jacking assembly is located on the right of the eight-channel probe adjusting device, and the taper sleeve assembly is located on the left of the eight-channel probe adjusting device; the eight-channel probe adjusting device, the tail jacking assembly and the taper sleeve assembly are respectively controlled by the motor, the portal frame motor and the taper sleeve motor to move left and right on the guide rail, and a rod is clamped for ultrasonic detection. The device is integrated by adopting multiple methods, is wide in application range and high in measurement precision, can timely acquire and intelligently analyze the detection result, and ensures the accuracy and reliability of the detection result.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic detection, and in particular relates to an ultrasonic detection device for uranium-based alloy fuel pellets. Background technique [0002] Uranium-based alloy pellets may have defects such as central shrinkage cavity, porosity, slag inclusion, longitudinal cracks and transverse cracks inside after extrusion and quenching from the billet ingot. Therefore, it is necessary to combine multiple ultrasonic testing methods for flaw detection of uranium-based alloy pellets to ensure their quality. [0003] At present, the ultrasonic flaw detection of uranium-based alloy pellets uses three ultrasonic testing equipment to complete the detection of various internal defects. It is beneficial to preservation, but it is difficult to meet the needs of modern production and testing. Contents of the invention [0004] The purpose of the present invention is to provide an ultrasonic detection device for uran...
