Description

Technical Field

[0001] This invention relates to the field of titanium forging inspection equipment, and in particular to a non-destructive testing device and method for annular titanium forgings. Background Technology

[0002] Nondestructive testing of annular titanium forgings utilizes the influence of differences in the acoustic properties of the material and its defects on the propagation of ultrasonic waves to examine internal defects in the material.

[0003] In existing technologies, the inspection devices for annular titanium forgings are mostly operated by workers who use handheld inspection devices to scan the inner or outer walls of the annular titanium forgings. This type of inspection device requires workers to hold it for a long time and move it constantly, which is relatively cumbersome and affects the convenience of the device during use. In addition, existing annular titanium forging inspection devices often require manual unloading during inspection, which is not convenient for automatic unloading, resulting in low inspection efficiency and increased labor intensity for workers.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0005] The primary objective of this application is to provide a non-destructive testing device for annular titanium forgings, comprising:

[0006] A ring-shaped support frame, with a conveyor installed below it;

[0007] The testing mechanism is located inside the ring support. The testing mechanism includes a centering component and a testing component. The centering component is used to center the workpiece to be tested and drive its rotation, and the testing component is used to perform non-destructive testing on the workpiece to be tested.

[0008] The feeding mechanism is located above the annular support.

[0009] The support mechanism is located at the bottom of the ring-shaped support.

[0010] Furthermore, the centering assembly includes a plurality of first hydraulic rods disposed on the outer wall of the annular support;

[0011] The output end of the first hydraulic rod passes through the annular bracket. A movable drive wheel is installed at the output end of the first hydraulic rod. Multiple drive wheels are coaxially arranged with connecting wheels on the same side. The same cooperating transmission component is sleeved on the multiple connecting wheels.

[0012] A tensioning component is provided on the inner wall of the annular bracket between two adjacent drive wheels. The tensioning component is used to ensure that the transmission component is always in contact with the connecting wheel.

[0013] Furthermore, the tensioning assembly includes two limiting wheels;

[0014] The transmission component is located within two limit wheels of multiple tensioning assemblies;

[0015] Each of the drive wheels is driven by a first drive motor.

[0016] Furthermore, the testing assembly includes a second hydraulic rod and a non-destructive testing head. The second hydraulic rod is disposed on the inner wall of the annular support, and the non-destructive testing head abuts against the outer wall of the workpiece to be tested. The non-destructive testing head is disposed at the output end of the second hydraulic rod.

[0017] Furthermore, the tensioning assembly also includes a third hydraulic rod, which is disposed on the inner wall of the annular bracket, and two limiting wheels are disposed at the output end of the third hydraulic rod.

[0018] Furthermore, the support mechanism includes a bracket connected to one end of the conveyor;

[0019] The support frame is provided with a protrusion along the width direction of the conveyor. The two ends of the protrusion near the annular support frame are respectively provided with a movable lead screw and a limiting rod. The end of the lead screw and the limiting rod away from the protrusion is provided with a fixed seat that is movably connected. The fixed seat is set on the conveyor.

[0020] The lead screw and the limit rod are fitted with the same support plate. The support plate is threaded to the lead screw and slidably connected to the limit rod. The lead screw is driven by a second drive motor.

[0021] Furthermore, the feeding mechanism includes a feeding cylinder located above the annular support;

[0022] The circumferential wall of the feeding cylinder is equipped with multiple sets of opposing conveying mechanisms, any one of which is driven by a third drive motor.

[0023] Furthermore, the conveying mechanism is equipped with multiple limit blocks, and the part to be tested is located between two adjacent limit blocks.

[0024] The second objective of this application is to provide a non-destructive testing method for annular titanium forgings using any of the above-mentioned non-destructive testing devices, comprising the following steps:

[0025] Step 1: Placement and fixation of the part to be tested. Start the feeding mechanism to make the part to be tested fall onto the support plate, and center and fix it by the centering component.

[0026] Step 2: Initial position detection. In a non-rotational state, the detection component scans the initial position of the part to be inspected to obtain the defect information of the initial position of the part to be inspected.

[0027] Step 3: Rotation detection. Start the first drive motor to make the part to be inspected rotate at a constant speed, and continuously scan the part to obtain the overall defect information of the part to be inspected through the detection component.

[0028] Step 4: Intelligent data analysis. The non-destructive testing system analyzes and processes the defect information of the part to be tested, and displays the analysis results through a display device.

[0029] By adopting the above technical solution, the present invention has the following beneficial effects:

[0030] By using a ring-shaped support and a testing mechanism, the testing mechanism can automatically perform non-destructive testing on the parts to be tested. Compared with existing technologies, this avoids muscle strain caused by workers holding the testing device for a long time and moving it constantly, thus improving the convenience of testing the parts to be tested. Furthermore, the setting of the unloading mechanism completes the automatic unloading of the parts to be tested. After the test is completed, the parts are transported to the next process by a conveyor, which reduces the labor intensity of the workers and improves the testing efficiency.

[0040] See Figures 1 to 5 As shown in the figure, this application embodiment provides a non-destructive testing device for annular titanium forgings, including: annular support 2, testing mechanism 5, unloading mechanism 4 and support mechanism 3. A conveyor 1 is arranged below the annular support 2. The annular support 2 is mounted on the crossbeams on both sides of the conveyor 1 by means of support legs. The testing mechanism 5 is arranged inside the annular support 2. The testing mechanism 5 includes a centering component and a testing component 56. There can be multiple testing components 56 to make the testing data more accurate. The centering component is used to center the workpiece 6 to be tested and drive it to rotate. The testing component 56 is used to perform non-destructive testing on the workpiece 6 to be tested. The unloading mechanism 4 is located above the annular support 2 and the support mechanism 3 is located at the bottom of the annular support 2.

[0041] In the above scheme, the ring support 2 and the detection mechanism 5 are set so that the detection mechanism 5 can automatically perform non-destructive testing on the workpiece 6 to be tested. Compared with the prior art, this avoids the muscle strain caused by the staff holding the detection device for a long time and moving it constantly, and improves the convenience of testing the workpiece 6. In addition, the unloading mechanism 4 completes the automatic unloading of the workpiece 6 to be tested. After the test is completed, it is transported to the next process by the conveyor 1, which reduces the labor intensity of the staff and improves the testing efficiency.

[0042] See some possible implementations. Figure 4As shown, the centering assembly includes multiple first hydraulic rods 51 disposed on the outer wall of the annular bracket 2. The multiple first hydraulic rods 51 are spaced apart, and the output end of the first hydraulic rod 51 passes through the annular bracket 2. A rotatable drive wheel 52 is installed on the output end of the first hydraulic rod 51. A connecting wheel 53 is coaxially disposed on the same side of the multiple drive wheels 52. The rotation of the drive wheel 52 drives the connecting wheel 53 to rotate. The multiple connecting wheels 53 are fitted with the same cooperating transmission component 54. The transmission component 54 is a belt, and the connecting wheel 53 is a pulley. A tensioning component 55 is disposed on the inner wall of the annular bracket 2 between two adjacent drive wheels 52. The tensioning component 55 is used to keep the transmission component 54 always in contact with the connecting wheel 53.

[0043] In the above scheme, when the test piece 6 falls onto the support mechanism 3, the first hydraulic rod 51 is activated, causing the output end of the first hydraulic rod 51 to extend. The extended output end of the first hydraulic rod 51 drives the drive wheel 52 to move towards the center of the ring bracket 2. When the multiple drive wheels 52 hold the test piece 6 against the ring bracket 2, the test piece 6 and the ring bracket 2 are in a concentric state, thus completing the centering of the test piece 6.

[0044] See some possible implementations. Figure 4 As shown, the tensioning assembly 55 includes two limiting wheels, and the transmission member 54 is located within the two limiting wheels of the multiple tensioning assemblies 55, wherein any one of the drive wheels 52 is driven by a first drive motor.

[0045] In the above scheme, after the centering of the workpiece 6 to be inspected is completed, the first drive motor is started, so that the output shaft of the first drive motor rotates and drives a drive wheel 52 to rotate. The rotation of the drive wheel 52 drives the connecting wheel 53 on it to rotate. The rotation of the connecting wheel 53 drives multiple connecting wheels 53 to rotate synchronously through the transmission component 54, thereby driving multiple drive wheels 52 to rotate synchronously, and then driving the workpiece 6 to be inspected to rotate. During the rotation of the workpiece 6, the detection component 56 completes the defect detection of the workpiece 6 to be inspected.

[0046] It should be noted that during the centering process of the test piece 6 and the disengagement process of the drive wheel 52 from the test piece 6, the tensioning component 55 needs to be adjusted synchronously to ensure that the transmission component 54 is always in contact with the connecting wheel 53 and the limiting wheel and does not disengage. The tensioning speed of the tensioning component 55 is greater than the moving speed of the drive wheel 52.

[0047] See some possible implementations. Figure 4 As shown, the testing component 56 includes a second hydraulic rod and a non-destructive testing head. The second hydraulic rod is disposed on the inner wall of the annular bracket 2, and the non-destructive testing head abuts against the outer wall of the workpiece 6 to be tested. The non-destructive testing head is disposed at the output end of the second hydraulic rod.

[0048] In the above scheme, since the diameter of the test piece 6 is different, after the test piece 6 is centered, the second hydraulic rod is activated, so that the output end of the second hydraulic rod extends and drives the non-destructive testing head to fit against the outer wall of the test piece 6.

[0049] See some possible implementations. Figure 4 As shown, the tensioning assembly 55 also includes a third hydraulic rod, which is disposed on the inner wall of the annular bracket 2, and two limiting wheels are disposed at the output end of the third hydraulic rod.

[0050] In the above scheme, when the drive wheel 52 moves toward the center of the annular bracket 2, in order to prevent the transmission component 54 from disengaging from the connecting wheel 53, the third hydraulic rod is activated, causing the output end of the third hydraulic rod to move toward the center of the annular bracket 2, so that the transmission component 54 is in a taut state; when the drive wheel 52 moves away from the center of the annular bracket 2, the third hydraulic rod is activated, causing the output end of the third hydraulic rod to move away from the center of the annular bracket 2, so that the transmission component 54 is in a taut state.

[0051] See some possible implementations. Figure 2 and Figure 3 As shown, the support mechanism 3 includes a bracket 31 connected to one end of the conveyor 1. A protrusion 32 is provided on the bracket 31 along the width direction of the conveyor 1. A movable lead screw 33 and a limiting rod 34 are respectively provided at both ends of the protrusion 32 near the annular bracket 2. A fixed seat 36 is provided at the end of the lead screw 33 and the limiting rod 34 opposite to the protrusion 32. The fixed seat 36 and the protrusion 32 are used to support the lead screw 33 and the limiting rod 34. The fixed seat 36 is set on the conveyor 1. The same support plate 35 is sleeved on the lead screw 33 and the limiting rod 34. The support plate 35 is used to support the test piece 6. The support plate 35 is threadedly connected to the lead screw 33. The support plate 35 is slidably connected to the limiting rod 34. The limiting rod 34 is used to limit the support plate 35 so that the support plate 35 will not rotate but can only move by screwing. The lead screw 33 is driven by the second drive motor 37.

[0052] In the above scheme, before the feeding mechanism 4 feeds the material, the second drive motor 37 is started, causing the output shaft of the second drive motor 37 to rotate. The rotation of the output shaft of the second drive motor 37 drives the lead screw 33 to rotate, and the rotation of the lead screw 33 drives the support plate 35 to screw, so that the support plate 35 moves to below the annular bracket 2. Then the second drive motor 37 is turned off, so that the part to be tested 6 on the feeding mechanism 4 falls onto the support plate 35.

[0053] See some possible implementations. Figure 5As shown, the feeding mechanism 4 includes a feeding cylinder 41 located above the annular support 2. The peripheral wall of the feeding cylinder 41 is provided with multiple sets of opposing conveying mechanisms. Each set of conveying mechanisms is driven by a third drive motor 45. Multiple limit blocks 44 are provided on the conveying mechanism, and the workpiece 6 to be tested is located between two adjacent limit blocks 44.

[0054] It should be noted that the conveying mechanism includes conveyor wheels 42 movably installed at the upper and lower ends of the feed cylinder 41. The same conveyor belt 43 is fitted on the two conveyor wheels 42. The conveyor wheels 42 can be pulleys or sprockets, and the conveyor belt 43 can be belts or chains. When the conveyor wheels 42 are pulleys, the conveyor belt 43 is a belt. When the conveyor wheels 42 are sprockets, the conveyor belt 43 is a chain. Multiple limit blocks 44 are evenly distributed on the conveyor belt 43.

[0055] A non-destructive testing method for annular titanium forgings using any of the above-mentioned non-destructive testing devices includes the following steps:

[0056] Step 1: Placement and fixation of the part to be tested 6. Start the feeding mechanism 4 so that the part to be tested 6 falls onto the support plate 35 and is centered and fixed by the centering component.

[0057] Step 2: Initial position detection. In a non-rotational state, the detection component 56 scans the initial position of the part to be inspected 6 to obtain defect information of the initial position of the part to be inspected 6.

[0058] Step 3: Rotation detection. Start the first drive motor to make the part to be inspected 6 rotate at a constant speed, and continuously scan the part to be inspected 6 through the detection component 56 to obtain the overall defect information of the part to be inspected 6.

[0059] Step 4: Intelligent data analysis. The non-destructive testing system analyzes and processes the defect information of the part 6 to be tested, and displays the analysis results through a display device.

[0060] It should be noted that the non-destructive testing device for annular titanium forgings provided in this application embodiment also includes a control system. The first hydraulic rod 51, the first drive motor, the second hydraulic rod, the third hydraulic rod, the second drive motor 37, and the third drive motor 45 are respectively connected to the control system via electrical signals. The control system is equipped with a non-destructive testing system, which provides a user interface. The detection component 56 is connected to the non-destructive testing system via electrical signals. The non-destructive testing system can use MATLAB calculation software. The MATLAB calculation software can process the defect information of the test piece 6 collected by the detection component 56, including images, sound, and vibration. Users can implement targeted data processing algorithms by writing scripts and functions. The user interface facilitates data visualization and result display for users.

[0061] By using the ring support 2 and the detection mechanism 5, the detection mechanism 5 can automatically perform non-destructive testing on the workpiece 6 to be tested. Compared with the existing technology, this avoids muscle strain caused by workers holding the detection device for a long time and moving it constantly, thus improving the convenience of testing the workpiece 6. Furthermore, the unloading mechanism 4 completes the automatic unloading of the workpiece 6 to be tested. After the test is completed, it is transported to the next process by the conveyor 1, which reduces the labor intensity of the workers and improves the testing efficiency. By using the ring titanium forging non-destructive testing method to process the defect information of the workpiece 6 collected by the detection component 56, the location and size of the defects in the workpiece 6 to be tested can be more intuitively displayed.

[0062] This specific embodiment is merely an explanation of the invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of protection of this invention, they are protected by patent law.
