DETAILED DESCRIPTION

[0023] In order to describe the technical content, structural features, achieved purposes and effects of the application in detail, the technical solutions in the embodiments of the application will be described below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all of the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but are not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0024] An embodiment of the present application provides an ultrasonic water immersion scanning device, which uses water as a medium to perform flaw detection on different types of workpieces.

[0025] like Figure 1 As shown, the scanning device 100 includes a frame 10, a water tank 20 for holding water, a roller mechanism 30 and a three-jaw chuck 40 mounted at the bottom of the water tank 20, and a detection mechanism 50 mounted above the water tank 20. The roller mechanism 30 is used to support workpieces such as rods and pipes, and the three-jaw chuck 40 is used to secure rotating workpieces such as gears. The installation of the roller mechanism 30 and the three-jaw chuck 40 expands the range of workpieces that the scanning device 100 can detect, improving the applicability of the scanning device 100.

[0026] The water tank 20 is installed on the frame 10 with its opening facing upward. The frame 10 is used to support the water tank 20 containing water, the detection mechanism 50 for detecting damage to the workpiece, and the workpiece on the ground.

[0027] like Figure 1 、 3 As shown, the roller mechanism 30 includes a pair of rollers 1 mounted at the bottom of the water tank 20 so as to be rotatable about their own axes. The rollers 1 are arranged parallel to each other. In the embodiment of the present application, the axes of each roller 1 extend in the left-right direction. The roller mechanism 30 also includes a roller motor (not shown) connected to at least one roller 1 for driving the at least one roller 1 to rotate about its own axis. A rod-shaped or tubular workpiece is placed between the pair of rollers 1. When one roller 1 rotates, the rod-shaped or tubular workpiece and the other roller 1 rotate about their own axes due to friction. The rod-shaped or tubular workpiece rotates with the rollers 1, making it easier for the detection mechanism 50 to detect it.

[0028] The three-jaw chuck 40 is disposed at the bottom of the water tank 20 and away from the roller mechanism 30. The three-jaw chuck 40 includes a turntable 2, three jaws 3, a jaw drive assembly (not shown), and a turntable drive motor (not shown). The turntable 2 has a centerline extending in the vertical direction. The three jaws 3 are equiangularly distributed on the upper surface of the turntable 2 around the centerline. The jaw drive assembly is connected to the three jaws 3 to drive the three jaws 3 to move synchronously back and forth along the radial direction of the centerline. The turntable drive motor is connected to the turntable 2 to drive the turntable 2 to rotate around the centerline. When installing a rotating workpiece, the jaw drive assembly drives the three jaws 3 to move outward simultaneously. After the rotating workpiece is installed on the turntable 2, the three jaws 3 simultaneously retract toward the centerline of the turntable 2 to clamp the rotating workpiece. The turntable drive motor drives the turntable 2 to rotate. The rotating workpiece rotates with the turntable 2 to facilitate the detection mechanism 50 to detect the rotating workpiece.

[0029] like Figure 1-3As shown, the inspection mechanism 50 includes a rotating probe 4 and a movable assembly 5. The movable assembly 5 is drivingly connected between the rotating probe 4 and the frame 10. The rotating probe 4 is configured to be rotatably mounted on the movable assembly 5 about an axis X1 extending in the vertical direction. The movable assembly 5 is configured to drive the rotating probe 4 to move in the front-to-back, vertical, and left-to-right directions relative to the water tank 20. The rotating probe 4 is an ultrasonic probe. When performing flaw detection on a workpiece, both the workpiece and the ultrasonic probe are immersed in the water in the water tank 20. Water immersion is used for ultrasonic flaw detection to improve detection sensitivity.

[0030] The moving assembly 5 includes a moving base 51, a moving bracket 52, a lifting base 53, a first driving member 54, a second driving member 55 and a third driving member 56. The moving base 51 can be installed on the frame 10 so as to be movable in the front-to-back direction, the moving bracket 52 can be connected to the moving base 51 so as to be movable in the left-right direction, the lifting base 53 can be connected to the moving bracket 52 so as to be movable in the up-down direction, and the rotating probe 4 is installed on the lifting base 53; the first driving member 54 is transmission-connected between the frame 10 and the moving base 51 to drive the moving base 51 to move back and forth relative to the frame 10 in the front-to-back direction, the second driving member 55 is transmission-connected between the moving base 51 and the moving bracket 52 to drive the moving bracket 52 to move back and forth relative to the moving base 51 in the left-to-right direction, and the third driving member 56 is transmission-connected between the moving bracket 52 and the lifting base 53 to drive the lifting base 53 to move back and forth relative to the moving bracket 52 in the up-down direction.

[0031] The movable base 51 is slidably installed on the top of the frame 10. The movable base 51, the movable bracket 52 and the lifting base 53 are all located above the water tank 20. The rotating probe 4 extends into the water tank 20 from top to bottom. When the movable component 5 drives the rotating probe 4 to move, it will not interfere with the workpiece at the bottom of the water tank 20.

[0032] The moving assembly 5 drives the rotating probe 4 to move forward and backward, left and right, and up and down. The rotating probe 4 can be adjusted to the vicinity of the workpiece. The rotating probe 4 rotates around the axis X1, thereby adjusting the angle of alignment with the workpiece, making it easier for the rotating probe 4 to scan and inspect the workpiece. When inspecting the movement of rod and tube workpieces, the rotating probe 4 is driven left and right by the moving bracket 52, thereby performing a grid scan on the workpiece. If the workpiece rotates with the roller 1 while the rotating probe 4 moves left and right, a spiral scan of the rod and tube workpiece is achieved. When inspecting rotating workpieces, the rotating probe 4 is driven up and down by the lifting base 53, thereby performing a grid scan of the workpiece. If the turntable 2 rotates while the lifting base 53 drives the rotating probe 4 up and down, a spiral scan of the rotating workpiece is achieved. Both spiral scanning and grid scanning can cover the entire workpiece, improving inspection efficiency and flaw detection accuracy.

[0033] In the embodiment of the present application, the first driving member 54, the second driving member 55 and the third driving member 56 are all linear motors. Linear motors are sensitive to response and have high movement efficiency, which can enable the rotating probe 4 to move into position quickly, thereby improving detection efficiency.

[0034] A first observation port is provided on the side wall of the water tank 20 and is covered with a first observation window 6. The first observation window 6 is made of a transparent material and is provided adjacent to the roller mechanism 30. The first observation window 6 allows an operator to observe the position of the rotating probe 4 at the roller mechanism 30 from the side from outside the water tank 20.

[0035] A second observation port is provided on the sidewall of the water tank 20, covered by a second observation window 7. This second observation window 7 is made of a transparent material and is located adjacent to the three-jaw chuck 40. The second observation port and the first observation port are located on two different sides of the water tank 20. The second observation port is larger than the first observation port. The second observation window 7 allows the user to observe the position of the rotating probe 4 on the roller mechanism 30 or the three-jaw chuck 40 from the outside of the water tank 20.

[0036] The first observation window 6 and the second observation window 7 facilitate the operator to observe the position of the rotating probe 4, thereby preventing the rotating probe 4 from colliding with the workpiece and causing damage to the equipment or the workpiece, thereby improving the safety of the operation.

Those skilled in the art should understand that the present application is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes.
