Detailed implementation manners

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0055] An ultrasonic detection device provided by an embodiment of the present invention includes:

[0056] The support beam 1 and the support base 5, where the support base 5 is used to support both ends of the support beam 1. The specific structure can be referred to Figure 1 and Figure 6 as shown;

[0057] The driving mechanism and the hinge 6, where the driving mechanism is arranged on the support beam 1;

[0058] The suspension rod 7, which includes: a sleeve 15, a bearing 16, a mandrel 17 and a sling 19; a mandrel 17 is sleeved inside the sleeve 15, a bearing 16 is arranged between the sleeve 15 and the mandrel 17, the outer wall of the sleeve 15 can be sleeved inside the through hole of the forging to be inspected 20, and slings 19 are respectively arranged at both ends of the mandrel 17. The specific structure can be referred to Figure 5 as shown;

[0059] Wherein, one end of the driving mechanism is connected to a sling 19 through a hinge 6, and the other end of the driving mechanism is connected to another sling 19 through another hinge 6. The specific structure can be referred to Figure 1 as shown.

[0060] In the above technical solution, by using the structural cooperation among the sleeve 15, the bearing 16 and the mandrel 17, the forging to be inspected 20 sleeved on the outer wall of the sleeve 15 can axially flip and align relative to the mandrel 17, so that the inspector can quickly eliminate the surface defect area or the area affecting ultrasonic inspection of the forging to be inspected 20, thereby improving the inspection efficiency of the forging to be inspected 20.

[0061] Optimizing the above technical solution, as Figure 5 shown, the function of the bearing 16 is to enable relative rotation between the sleeve 15 and the mandrel 17. In order to make the relative rotation between the sleeve 15 and the mandrel 17 smoother, and also to avoid the situation that the device cannot be used due to mechanical failure when only a single bearing 16 is provided during use, the number of bearings 16 is multiple, and the multiple bearings 16 are evenly spaced along the axial direction of the mandrel 17; it should be noted that the inner ring of the bearing 16 is sleeved on the outer wall of the mandrel 17, and the outer ring of the bearing 16 is sleeved on the inner wall of the sleeve 15; preferably, there are three bearings 16, which are evenly spaced between the mandrel 17 and the sleeve 15.

[0062] Further optimizing the above technical solution, as Figure 5As shown, a limiting ring 18 is provided between the end of the casing 15 and the end of the mandrel 17. The limiting ring 18 can fix the casing 15 at the corresponding position on the mandrel 17. In one embodiment, the number of limiting rings 18 is two. One limiting ring 18 is arranged between the first end of the casing 15 and the first end of the mandrel 17, and the other limiting ring 18 is arranged between the second end of the casing 15 and the second end of the mandrel 17. In one embodiment, the limiting ring 18 is circular, with a width of 20 mm, a maximum outer diameter of 100 mm, and a coarse thread of M48 is machined on the inner diameter.

[0063] In an alternative embodiment, as Figure 1 shown, at least two guide post structures arranged at intervals are provided along the axial direction on the bottom side of the support beam 1.

[0064] The driving mechanism includes:

[0065] A rotating shaft 3, both ends of the rotating shaft 3 are respectively rotationally assembled with the corresponding guide post structures. A rotating gear 13 is sleeved on the rotating shaft 3. Both ends of the rotating shaft 3 are also respectively connected to the fixed ends of the corresponding hinges 6. The free ends of the hinges 6 are connected to the lifting rings 19 to realize the locking and release of the lifting rings 19, which is convenient for the assembly connection of the hinges 6 and the lifting rings 19. The specific structure can refer to Figure 4 shown;

[0066] A motor 2, the motor 2 is arranged on the support beam 1, and a motor gear 21 is provided at the output end of the motor 2. The motor gear 21 and the rotating gear 13 are meshed with each other, so that under the drive of the motor 2, the rotating shaft 3 drives the hanging rod 7 to move up and down through the hinge 6. The specific structure can refer to Figure 1 and Figure 6 shown.

[0067] In the above technical solution, the principle of this ultrasonic detection device is that the forging 20 to be detected is sleeved on the casing 15 through its through hole, as Figure 6 shown. The lifting ring 19 and the rotating shaft 3 are connected by using the hinge 6, and then the motor 2 is started. The motor 2 drives the rotating shaft 3 to rotate by the meshing of the machine gear 21 and the rotating gear 13. During the rotation of the rotating shaft 3, the hinge 6 is tightly wound around the rotating shaft 3 in a surrounding manner, so that the rotational motion is converted into a linear up-and-down motion. As the hinge 6 is wound around the rotating shaft 3 one by one, the forging 20 to be detected is lifted. When it is lifted to a preset height, ultrasonic detection is carried out on the forging 20 to be detected. In addition, the downward movement process of the forging 20 to be detected is similar to the above, and will not be elaborated one by one here.

[0068] To optimize the above technical solution, as Figure 1 and Figure 2As shown in the figure, the guide post structure includes: a guide post 10 provided on the bottom side of the support beam 1. The guide post 10 is provided with a through hole, and the axial direction of the through hole is parallel to the axial direction of the support beam 1. The outer wall of the end of the rotating shaft 3 is rotatably installed in the through hole. In this technical solution, the motor 2 drives the rotating shaft 3 to rotate relative to the through hole, and the through hole plays a role in fixing the rotating shaft 3.

[0069] Optimize the above technical solution, such as Figure 4 As shown in the figure, hinge grooves 14 are respectively provided at both ends of the rotating shaft 3. The hinge grooves 14 are used to connect the fixed ends of the hinges 6. The hinge grooves 14 restrict the movement trajectory, which is manifested as restricting the movement range of the hinges 6, ensuring that the suspension rods 7 connected thereto can only rotate or swing at specific angles and directions; it can be understood in this way that the hinge grooves 14 ensure the movement stability by restricting the movement of the hinges 6, and the hinge grooves 14 contribute to improving the stability of this device.

[0070] Further optimize the above technical solution, such as Figure 1 As shown in the figure, in order to make the motor 2 move more smoothly and the structure more stable during the driving process, along the axial direction of the rotating shaft 3, one hinge groove 14, one guide post structure, another guide post structure and another hinge groove 14 are arranged in sequence.

[0071] In an alternative embodiment, such as Figure 1 and Figure 2 As shown in the figure, the support base 5 includes a first support and a second support; one end of the support beam 1 is arranged at the top of the first support, and the other end is arranged at the top of the second support, so as to form a detection space between the bottom side of the support beam 1, the first support and the second support. The forging to be inspected 20 is located in this detection space after installation. The specific structure can refer to Figure 1 and Figure 6 As shown in the figure.

[0072] Optimize the above technical solution, such as Figure 2 As shown in the figure, lifting lugs 8 are provided on the top side of the support beam 1. The lifting lugs 8 are used for lifting and long-distance movement of the whole device. Preferably, the number of lifting lugs 8 is two; and / or,

[0073] Both ends of the bottom side of the support beam 1 are respectively fixed to the first support and the second support through bolts 4. The bolt fixation is convenient for disassembly and maintenance, and is conducive to rapid assembly.

[0074] In an embodiment, such as Figure 2As shown in the figure, the support beam 1 has an I-shaped cross-section with a cross-sectional height of 100 mm, upper and lower flange widths of 50 mm, a web thickness of 9 mm, and a length of 2000 mm. Lifting lugs 8 are welded to both ends of the upper flange of the I-beam for the lifting and long-distance movement of the entire hanger. On the inner surface of both ends of the lower flange, two square counterbores 9 are machined, and the two counterbores are symmetrically distributed with the web as the center. The depth of the counterbore is 1 mm to 3 mm. Two mounting first bolt through-holes are machined on each square counterbore 9 for connecting the support beam 1 and the support base 5. A square guide post 10 for mounting the hinge shaft 3 is welded to the outside of the lower flange, with a guide post spacing of 1000 mm to 1500 mm, and a through-hole for mounting the hinge shaft 3 is machined on the guide post.

[0075] In one embodiment, as Figure 3 shown, the support base 5 has a steel frame structure, including a connecting seat 11 and a welded steel frame 12. The connecting seat 11 is square, and four mounting second bolt through-holes are machined on it. The positions of the second bolt through-holes correspond to those of the first bolt through-holes. The first support includes a connecting seat 11 and a steel frame 12, and the second support includes a connecting seat 11 and a steel frame 12. The steel frames 12 are all in an A shape, with a height of 1000 mm to 1500 mm, and the top ends are welded to the connecting seat 11. Among them, the first support and the second support are both connected to the support beam 1 through four bolts.

[0076] In one embodiment, as Figure 4 shown, the main body of the rotating shaft 3 is a steel pipe with an outer diameter of Φ30 mm to Φ60 mm and a wall thickness of 5 mm to 8 mm, and the total length is 1400 mm. There is a rotating gear 13 at the middle position of the rotating shaft 3 for transmitting the torque of the motor 2 (i.e., the rotating motor) to the hinge shaft (i.e., the rotating shaft 3). At a distance of 60 mm from both ends of the hinge shaft, there is a hinge groove 14 for defining the position where the hinge is wound. The hinge shaft is installed in the through-hole of the square guide post 10 above the support beam 1.

[0077] In one embodiment, as Figure 1 and Figure 5 shown, the suspension rod 7 is rod-shaped, including a sleeve 15, a bearing 16, a core rod 17, a limit ring 18, and a lifting ring 19. The outer diameter of the sleeve 15 is 100 mm, the wall thickness is 5 mm, and the length is 1100 mm. The outer diameter of the core rod 17 is 50 mm, the wall thickness is 10 mm, and the length is 1200 mm. The outer diameter of both ends of the head is machined with a coarse-thread external thread of M48, with a thread length of 80 mm, and the inner diameter is machined with a coarse-thread external thread of M32, with a thread length of 60 mm. The lifting ring 19 is rod-shaped, with a diameter of 50 mm and a length of 100 mm. One end is machined with a coarse-thread external thread of M32, with a thread length of 50 mm, and the other end is machined with a lifting through-hole of Φ20 mm.

[0078] In one embodiment, during assembly, first insert the mandrel 17 into the inner diameter of the sleeve 15, then place the three bearings 16 equidistantly between the mandrel 17 and the sleeve 15, then install the limit rings 18 at both ends to fix the sleeve 15 in the middle, and finally install the lifting rings 19 on both sides of the mandrel 17.

[0079] A method for ultrasonic testing, using the ultrasonic testing device described above, as Figure 7 shown, includes the steps:

[0080] S1: Place the ultrasonic testing device equipped with the forging 20 to be tested in the ultrasonic testing area, and the driving mechanism lifts the forging 20 to be tested to a preset height, as Figure 6 shown, and the preset height is set according to needs;

[0081] In the above solution, when the ultrasonic testing is carried out by the testing device of the present invention, the ground of the testing area should be flat, the longitudinal inclination of the support beam 1 should not be greater than 5°, and the transverse inclination should not be greater than 10°. Place the forging 20 to be tested directly below the support beam 1. First insert the suspension rod 7 into the central through hole of the forging 20 to be tested, then insert the hook on the hinge 6 into the lifting ring 19 on the suspension rod, and then operate the motor 2 to lift the suspension rod 7 and the forging 20 to be tested together to the testing height (i.e., the preset height).

[0082] S2: Flip the forging 20 to be tested and check whether there are defect areas or areas affecting ultrasonic testing on the surface of the forging 20 to be tested. If there are no defect areas or areas affecting ultrasonic testing, then determine the forging 20 to be tested as the final forging 20 to be tested; if there are defect areas or areas affecting ultrasonic testing, then machine-process and eliminate the defect areas or areas affecting ultrasonic testing to obtain the final forging 20 to be tested;

[0083] S3: Carry out ultrasonic testing on the final forging 20 to be tested to confirm the defect positions existing in the forging 20 to be tested, which can be understood as carrying out ultrasonic testing on the inside of the forging 20 to be tested.

[0084] In the above technical solution, it is possible to quickly check the surface of the forging 20 to be tested and machine-process and eliminate it, thereby reducing the safety risk of personnel operation and the labor intensity of the testing personnel, and improving the accuracy and safety of forging testing.

[0085] Optimizing the above technical solution, carrying out ultrasonic testing on the final forging 20 to be tested to confirm the defect positions existing in the forging 20 to be tested, includes:

[0086] Taking the axis of the final forging 20 to be tested as the Z axis, setting one direction as the X axis and the other direction as the Y axis in any two mutually perpendicular directions on the cross-section of the final forging 20 to be tested, and the cross-section is perpendicular to the direction of the Z axis, which can be referred to Figure 6as shown by the coordinate axes;

[0087] Using ultrasonic waves to start detecting from the first surface of the final forging 20 to be inspected. If a suspected defect signal is detected, record the depth of the first signal position , the first surface is perpendicular to the direction of the X-axis; among them, the depth of the first signal position (Xi can be the coordinate positions of X1, X2,..., Xn);

[0088] Using ultrasonic waves to start detecting from the second surface of the final forging 20 to be inspected. If a suspected defect signal is detected, record the depth of the second signal position , the second surface is perpendicular to the direction of the Y-axis; among them, the depth of the second signal position (Yi can be the coordinate positions of Y1, Y2,..., Yn);

[0089] If suspected defect signals exist simultaneously in the X-axis direction or the Y-axis direction, it is determined as a cavity or inclusion defect;

[0090] Determine the (X, Y) coordinates of the cavity, inclusion defect, crack or fold defect. Taking one end of the final forging 20 to be inspected as the reference point of the Z-axis coordinate, determine the Z-axis coordinate of the (X, Y) coordinates.

[0091] In the above solution, by constructing the coordinate axes and then using ultrasonic waves to measure the X-axis direction and the Y-axis direction respectively, the internal defect situation of the forging 20 to be inspected can be quickly detected; it should be noted that for the determination of the Z-axis coordinate reference point, it can be based on the rightmost side of the forging 20 to be inspected (such as Figure 6 's rightmost side), or it can be based on the leftmost side of the forging 20 to be inspected (such as Figure 6 's leftmost side).

[0092] Further optimize the above technical solution. After using ultrasonic waves to start detecting from the second surface of the final forging 20 to be inspected, if a suspected defect signal is detected, record the depth of the second signal position , after the second surface is perpendicular to the direction of the Y-axis, it further includes:

[0093] Using ultrasonic waves to start detecting from the third surface of the final forging 20 to be inspected. If a suspected defect signal is detected, record the depth of the third signal position , the third surface is perpendicular to the direction of the X-axis, and the third surface and the first surface are symmetrically arranged;

[0094] Using ultrasonic waves to start detecting from the fourth surface of the final forging 20 to be inspected. If a suspected defect signal is detected, record the depth of the fourth signal position , the fourth surface is perpendicular to the direction of the Y-axis, and the fourth surface and the second surface are symmetrically arranged;

[0095] If = the thickness of the forging to be inspected 20 in the X-axis direction - , = the thickness of the forging to be inspected (20) in the Y-axis direction - , then the detected defect is a point defect;

[0096] If < the thickness of the forging to be inspected 20 in the X-axis direction - , = the thickness of the forging to be inspected (20) in the Y-axis direction - ; then the detected defect is a line defect;

[0097] If < the thickness of the forging to be inspected 20 in the X-axis direction - , < the thickness of the forging to be inspected 20 in the Y-axis direction - ; then the detected defect is a surface defect.

[0098] In the above technical solution, the coordinate position of the detected defect can be reconfirmed, and further confirmed as a point defect, a line defect or a surface defect; after this technical solution, the inspected forging is removed from the device, and the rotating motor 2 is operated to lower the suspension rod 7 and the forging together. After the forging is placed on the bottom surface, the suspension rod 7 is taken out from the central hole of the forging to complete the ultrasonic inspection of the forging.
