Description

Technical Field

[0001] This utility model belongs to the field of ultrasonic automated flaw detection technology in non-destructive testing, specifically relating to a dual-station probe holder for an automated testing system for pipes. Background Technology

[0002] Conventional automated pipe inspection probe frames are typically single-station designs, which introduce blind spots or lead to missed detections due to decreased sensitivity caused by the reversibility of defects. This fails to meet user needs. Therefore, the automated pipe inspection system of this invention employs a dual-station design for its probe frame. Each station uses a cylinder to control an independent water immersion focusing probe, which descends alternately to inspect the workpiece. Each probe frame has an X-axis micro-adjustment module, which adjusts the probe's eccentricity relative to the workpiece to ensure the incident angle for pipes of different wall thicknesses. The two sets of probes enter from both sides of the pipe's circumference to ensure that defects in different directions are not missed. Utility Model Content

[0003] Purpose of the utility model: In order to overcome the shortcomings of the existing technology, this utility model provides a dual-station probe holder for an automated inspection system for pipes, which ensures that defects in different directions are not missed during ultrasonic water immersion testing, and at the same time ensures that there are no blind spots at the beginning and end of the workpiece being inspected.

[0004] Technical solution: A dual-station probe frame for an automated inspection system for pipes, comprising: an X-axis linear module, a module connecting plate, a Z-axis linear module, a cylinder, a cylinder connecting plate, a dovetail groove slide adjustment module, an L-shaped connecting plate, a water immersion focusing probe one, and a water immersion focusing probe two;

[0005] The X-axis linear module and the Z-axis linear module are fixedly connected by a module connecting plate;

[0006] The X-axis linear module is equipped with a transverse slide rail. The module connecting plate moves laterally in the X-axis direction via the transverse slide rail, thereby driving the Z-axis linear module to move laterally.

[0007] The Z-axis linear module is fixedly equipped with dual-position probes: water immersion focusing probe one and water immersion focusing probe two. Water immersion focusing probe one and water immersion focusing probe two are respectively fixedly connected to cylinders, and the up and down movement of water immersion focusing probe one and water immersion focusing probe two are controlled by the two cylinders respectively.

[0008] As an optimization: the cylinder is fixedly connected to the dovetail groove slide adjustment module via a cylinder connecting plate.

[0009] As an optimization: the water immersion focusing probe is fixedly connected to the dovetail groove slide adjustment module via an L-shaped connecting plate.

[0010] As an optimization: the second water immersion focusing probe is fixedly connected to the dovetail groove slide adjustment module via an L-shaped connecting plate.

[0011] Beneficial effects: The automated inspection system of this utility model has high motion accuracy of the dual-station probe frame, good coupling stability, strong adaptability, and high structural reliability. It ensures that defects in different directions are not missed during ultrasonic water immersion testing, and at the same time ensures that there are no blind spots at the beginning and end of the workpiece being inspected.

[0013] Example

[0014] like Figure 1 As shown, a dual-station probe frame for an automated inspection system for pipes includes: an X-axis linear module 1, a module connecting plate 2, a Z-axis linear module 3, a cylinder 4, a cylinder connecting plate 5, a dovetail groove slide adjustment module 6, an L-shaped connecting plate 7, a water immersion focusing probe 1 81, and a water immersion focusing probe 2 82.

[0015] In this embodiment, the X-axis linear module 1 and the Z-axis linear module 3 are fixedly connected by a module connecting plate 2. The X-axis linear module 1 is provided with a transverse slide rail 11, and the module connecting plate 2 moves laterally in the X-axis direction via the transverse slide rail 11, thereby driving the Z-axis linear module 3 to move laterally.

[0016] In this embodiment, a dual-position probe is fixedly installed on the Z-axis linear module 3: a water immersion focusing probe one 81 and a water immersion focusing probe two 82. The water immersion focusing probe one 81 and the water immersion focusing probe two 82 are each fixedly connected to a cylinder 4, and the up-and-down movement of the water immersion focusing probe one 81 and the water immersion focusing probe two 82 is controlled by the two cylinders 4 respectively. Specifically, the cylinder 4 is fixedly connected to the dovetail slide adjustment module 6 via a cylinder connecting plate 5, and the water immersion focusing probe one 81 and the water immersion focusing probe two 82 are fixedly connected to the dovetail slide adjustment module 6 via L-shaped connecting plates 7.

[0017] This utility model's automated pipe inspection system employs a dual-station design for its probe holder. Each station uses a cylinder to control an independent water immersion focusing probe, which descends alternately to inspect the workpiece. Each probe holder has a dovetail slide adjustment module, which adjusts the probe's eccentricity relative to the workpiece to ensure the incident angle for pipes of different wall thicknesses. Two sets of probes enter from both sides of the pipe's circumference to ensure no defects in different directions are missed. The probe holder is fixed to a linear module using a triangular support for parallel scanning along the pipe. The triangular support backplate is connected to the probe holder via the Z-axis linear module, allowing the probe holder to be adjusted to accommodate pipes of different diameters.
