Abstract

An inspection system for performing an inspection of an end region of a part is provided. The inspection system includes a robotic assembly positioned along a side of the part. The inspection system includes an ultrasonic probe coupled to the robotic assembly and positioned in proximity to the end region of the part. The ultrasonic probe is moved by the robotic assembly along a path to inspect the end region of the part. During the inspection, the ultrasonic probe transmits a signal towards the end region of the part and receives a reflected signal from the end region of the part. The inspection system provides, as a single system, for inspection of both a body of the part and the end region of the part.

First claim

What is claimed:

1. An inspection system, comprising:
a robotic assembly configured to be positioned along a side of a part;
an ultrasonic probe coupled to the robotic assembly; and
a control unit in communication with the robotic assembly and the ultrasonic probe, the control unit configured to:
receive geometry information related to dimensional characteristics of the part at a central region and an end region extending from a transition junction to a terminal end of the part; and
transmit first instructions to the robotic assembly, the first instructions being operative to cause the robotic assembly to position the ultrasonic assembly at a first position adjacent to the central region of the part, a second position adjacent to the end region of the part, and a third position adjacent to the transition junction of the part; and
transmit second instructions to the ultrasonic probe, the second instructions being operative to cause the ultrasonic probe to,
generate a first ultrasonic beam with a first shape at the first position;
generate a second ultrasonic beam at the second position that is focused at the terminal end of the part, and
generate a third ultrasonic beam at the third position that is focused at a geometric change at an inner diameter of the part at an end of the transition region;
wherein the second and third shapes are different from the first shape.

2. The inspection system of claim 1 , wherein the ultrasonic probe comprises a phased array probe.

3. The inspection system of claim 1 , wherein an angle of inclination of the ultrasonic probe with respect to the end region of the part is configured to be adjusted by the robotic assembly.

4. The inspection system of claim 1 , wherein the ultrasonic probe is configured to be moved by the robotic assembly along a plurality of axes.

5. The inspection system of claim 1 , wherein the path along which the ultrasonic probe is moved adapts to a geometry of the end region of the part.

6. The inspection system of claim 1 , wherein the path along which the ultrasonic probe is moved comprises a pre-programmed path.

7. The inspection system of claim 1 , comprising a fluid delivery structure coupled to the robotic assembly, the fluid delivery structure configured to deliver a fluid to the end region of the part.

8. The inspection system of claim 1 , including a programmable logic controller that is set to provide harmonization between the position of the ultrasonic probe and the geometry of the part.
