Description

Technical Field

[0001] The present application relates to the technical field of pipe inspection equipment, and in particular to a quenching tube eddy current flaw detection equipment. Background Art

[0002] Eddy current testing is one of many NDT (non-destructive testing) methods. The eddy current principle can be used to solve problems such as metal material flaw detection (crack and defect inspection), thickness measurement (material or coating thickness measurement), and sorting. Usually, the eddy current testing equipment for quenching tubes is generally carried by hand to the testing station, and then the probe is used to test the quenching tube.

[0003] With respect to the above-mentioned related technologies, the traditional detection method requires manual transportation of the quenching tube to the detection station for detection each time, and after the detection is completed, the quenching tube needs to be manually moved out of the detection station. The efficiency of the transportation method of manually transporting the quenching tube for detection and manually moving the quenching tube out of the detection station is too low, resulting in low detection efficiency of the quenching tube.

[0037] The following is combined with Figure 1-6 This application is described in further detail.

[0038] The embodiment of the present application discloses a quenching tube eddy current flaw detection device.

[0039] like Figure 1 , Figure 2 and Figure 3 A quenching tube eddy current flaw detection equipment includes a workbench 1, a detection device 2 and four supporting plates 3. The detection device 2 is arranged on the workbench 1, and each two supporting plates 3 form a group. A spacing matching the length of the quenching tube to be detected is left between the two groups of supporting plates 3. The four supporting plates 3 are parallel to each other. The two supporting plates 3 located on the outer sides can be movably arranged on the workbench 1. Two driving members 31 are arranged on the workbench 1. The two driving members 31 are both first cylinders 311. The first cylinders 311 correspond to the movable supporting plates 3 one by one and the piston rod of the first cylinder 311 is fixed to the bottom of the movable supporting plates 3. The two supporting plates 3 located on the inner sides are fixed on the workbench 1.

[0040] like Figure 3The top surface of the support plate 3 is provided with support grooves 32 at equal intervals along the length direction, one side wall of the support groove 32 is an inclined wall 321, and the inclined wall 321 is inclined downward toward the detection device 2, the other side wall of the support groove 32 is a vertical wall 322 pointing vertically downward, and the bottom surface of the support groove 32 is an arc surface 323. The support grooves 32 of the two support plates 3 in the same group are staggered, the support grooves 32 of the two movable support plates 3 are aligned one by one with each other, and the support grooves 32 of the two fixed support plates 3 are aligned one by one with each other.

[0041] like Figure 1 and Figure 2 A first workstation 4 is provided at one end of the support plate 3 close to the detection device 2, and a first workstation slot 41 is provided on the top surface of the first workstation 4. The side wall of the first workstation slot 41 close to the support plate 3 is inclined downward, and its inclination direction is the same as the inclination direction of the inclined wall 321 of the support slot 32. The side wall of the first workstation slot 41 away from the support plate 3 is vertically downward, and the top surface of the first workstation slot 41 is set as an inclined surface 42.

[0042] like Figure 2 The end of the support plate 3 fixed on the workbench 1 near the detection device 2 is provided with a second station 5 for positioning the quenching tube for internal flaw detection. The second station 5 is provided with a second station slot 51, which is a V-shaped slot. The workbench 1 is provided with a movable support 52, which is arranged on one side of a group of support plates 3. The workbench 1 is provided with a third servo drive unit 53 for driving the movable support 52 to move. The movable support 52 is provided with a second probe 54, which is aligned with the second station slot 51.

[0043] A material box 7 is arranged on the workbench 1 . The material box 7 is arranged obliquely on the workbench 1 and is located above the supporting plate 3 .

[0044] like Figure 1 A first discharge plate 11 is hinged on the workbench 1, and a flip assembly 6 for driving the first discharge plate 11 to flip is provided on the workbench 1. The first discharge plate 11 is located above the first workstation 4, and a clamping groove 111 matching the first workstation is opened on the first discharge plate 11. A second discharge plate 12 is provided on the workbench 1, and the first discharge plate 11 is located above the second discharge plate 12. One end of the first workstation 4 extends into the second discharge plate 12.

[0045] When testing the quenching tube, the material box 7 containing the quenching tube to be tested is placed on the workbench 1, and the material box 7 is tilted and placed above the support plate 3. The quenching tube is accumulated and falls into the first support groove 32 of the fixed support plate 3 due to gravity, and then the first cylinder 311 drives the movable support plate 3 to move upward, and the inclined wall 321 of the first support groove 32 of the movable support plate 3 cooperates with the vertical wall 322 of the fixed support plate 3 to lift the quenching tube upward. When the inclined wall 321 of the support groove 32 of the movable support plate 3 is above the fixed support plate 3, the quenching tube is lifted upward. When the quenching tube moves to the supporting trough 32 of the movable supporting plate 3, the quenching tube rolls into the bottom of the supporting trough 32 along the inclined wall 321 of the supporting trough 32 of the movable supporting plate 3, and then the movable supporting plate 3 is lowered, and the quenching tube falls on the inclined wall 321 of the second supporting trough 32 of the fixed supporting plate 3 and rolls to the bottom of the trough along the inclined wall 321. Through the above repeated movements, the quenching tube moves toward the direction close to the detection device 2 and the quenching tube is laid flat on the supporting plate 3 during the movement so that there is only one quenching tube in the supporting trough 32 close to the detection device 2, and automatic transfer one by one is realized without mutual interference.

[0046] When the quenching tube is transferred to the second station 5, the third servo drive unit 53 drives the movable support 52 to move, and the movable support 52 drives the second probe 54 to insert into the quenching tube for internal flaw detection. If the quenching tube fails the inspection, the quenching tube is transferred to the first station 4 and the detection device 2 does not participate in the inspection. At this time, the flip assembly 6 drives the first discharge plate 11 to be clamped on the first station 4, and the detection device 2 cooperates with the first station 4 to drop the unqualified quenching tube on the first station 4, and then the flip assembly 6 is reset to complete the collection of the unqualified quenching tube. If the internal flaw detection of the quenching tube is qualified, the quenching tube will be transferred to the first work station 4 for peripheral surface flaw detection. If the detection is unqualified, the flip assembly 6 continues to drive the first discharge plate 11 to collect the unqualified quenching tube. If the detection is qualified, the detection device 2 drives the quenching tube to slide along the first work station 4 into the second discharge plate 12, thereby realizing flaw detection on the peripheral surface and interior of the quenching tube, and realizing automatic screening of the quenching tube, thereby improving the detection efficiency of the quenching tube.

[0047] like Figure 1 , Figure 4 and Figure 5 The detection device 2 includes a first ejector pin 21, a second ejector pin 22, and a rotating assembly 23 for driving the first ejector pin 21 and the second ejector pin 22 to clamp the quenching tube and drive the quenching tube to rotate. The rotating assembly 23 is arranged on the workbench 1, and the first workstation 4 is located in the rotating assembly 23. The workbench 1 is provided with a lifting assembly 24 for driving the quenching tube to move up and down so that it is aligned with the first ejector pin 21 and the second ejector pin 22. The workbench 1 is provided with a detection assembly 25 for detecting the outer peripheral surface of the quenching tube. The detection assembly 25 is located above the rotating assembly 23. The two first workbenches 1 are both located in the rotating assembly 23 and are respectively located on each side of the lifting assembly 24.

[0048] When performing peripheral surface flaw detection on the quenching tube, the lifting assembly 24 drives the quenching tube to separate from the first workbench 1 and lifts the quenching tube to align with the first ejector pin 21 and the second ejector pin 22, and then the rotating assembly 23 drives the first ejector pin 21 and the second ejector pin 22 to clamp the quenching tube and rotate the quenching tube, then the detection assembly 25 performs peripheral surface flaw detection on the rotating quenching tube, the rotating assembly 23 drives the first ejector pin 21 and the second ejector pin 22 to release the fixation of the quenching tube, and then the lifting assembly 24 drives the quenching tube to descend and slide out of the rotating assembly 23 along the top surface of the first workbench 4, thereby realizing eddy current flaw detection on the quenching tube.

[0049] like Figure 1 , Figure 4 and Figure 5 The rotating assembly 23 includes a reference ejector seat 231 and a floating ejector seat 232. The first ejector 21 is rotatably connected to the reference ejector seat 231, and the second ejector 22 is rotatably connected to the floating ejector seat 232. The reference ejector seat 231 and the floating ejector seat 232 are both slidably arranged on the workbench 1. The ends of the first ejector 21 and the second ejector 22 are both cones. The floating ejector seat 232 is provided with a motor 233 for driving the second ejector 22 to rotate. The workbench 1 is provided with a first servo drive unit 234 for driving the floating ejector seat 232 to move. The lifting assembly 24 and the first workstation 4 are both located between the reference ejector seat 231 and the floating ejector seat 232. The detection assembly 25 is located between the reference ejector seat 231 and the floating ejector seat 232 and above the reference ejector seat 231 and the floating ejector seat 232.

[0050] When the quenching tube is located on the first workbench 1, the lifting assembly 24 drives the quenching tube to rise and aligns the quenching tube with the first ejector pin 21 and the second ejector pin 22, and then the first servo drive unit 234 drives the floating ejector seat 232 to approach the reference ejector seat 231, and inserts the second ejector pin 22 into the quenching tube and pushes the other end of the quenching tube into the first ejector pin 21 to fix the quenching tube, and then starts the motor 233, which drives the second ejector pin 22 to rotate, and the second ejector pin 22 drives the quenching tube and the first ejector pin 21 to rotate, so that the detection assembly 25 can detect the outer peripheral surface of the quenching tube.

[0051] like Figure 1 and Figure 5The lifting assembly 24 includes a work station plate 241 and two support plates 242. A lifting plate 243 is movably arranged on the workbench 1. Support columns 244 are arranged at the four corners of the lifting plate 243. The work station plate 241 is arranged on the support plate 242. A second servo drive unit 245 for adjusting the movement of the lifting plate 243 is arranged on the workbench 1. The two support plates 242 are respectively arranged on one side of the work station plate 241. The support plate 242, the work station plate 241 and the lifting plate 243 are all located between the floating ejector seat 232 and the reference ejector. A support groove 246 is provided on the support plate 242, one first workstation 4 is located between the support plate 242 and the floating ejector seat 232 near the floating ejector seat 232, and another first workstation 4 is located between the support plate 242 and the reference ejector seat 231 near the reference ejector seat 231, the first workstation grooves 41 of the first workstation 4 and the support grooves 246 of the support plate 242 are alternately distributed, the support grooves 246 of the two support plates 242 are aligned, and the first workstation grooves 41 of the two first workstations 4 are aligned.

[0052] When the quenching tube is in the state to be inspected, the quenching tube transferred to the first work station 4 is located on the inclined side wall of the first work station groove 41, and the quenching tube abuts against the side wall of the support plate 242. When the quenching tube needs to be inspected, the first cylinder 311 drives the supporting plate 3 to lift the first work station 4, so that the quenching tube is located at the bottom of the first work station groove 41 and abuts against the vertical downward side wall of the first work station groove 41, and then the second servo drive unit 245 drives the lifting plate 243 to move upward, and the lifting plate 243 drives the work station plate 241 and the support plate 242 to lift upward, and the support plate 242 drives the quenching tube to separate from the first work station plate 241 and makes the quenching tube fall into the support groove 246, and as the lifting plate 243 continues to lift, the quenching tube continues to rise to align with the first ejector pin 21 and the second ejector pin 22, so that the first ejector pin 21 and the second ejector pin 22 can be inserted into the quenching tube to fix the quenching tube.

[0053] When the quenching tube inspection is completed, the first ejector pin 21 and the second ejector pin 22 are separated, so that the quenching tube falls back on the supporting groove 246, and then the second servo drive unit 245 drives the lifting plate 243 to descend, and the lifting plate 243 drives the work station plate 241 and the support plate 242 to descend. When the support plate 242 descends to a certain distance, the quenching tube contacts the top surface of the first work station 4 and separates from the support plate 242. The quenching tube slides out of the work station plate 241 along the top surface of the first work station 4, thereby realizing the discharge of the quenching tube.

[0054] like Figure 4The detection component 25 includes a first probe 251 and a dual-coordinate moving platform 252. The dual-coordinate moving platform 252 is arranged on the workbench 1.

An eighth servo drive component for driving the sliding block 254 to move is arranged on the first moving track. The first probe 251 is arranged on the moving block 253 and is located between the floating ejector seat 232 and the reference ejector seat 231. The first moving track is parallel to the quenching tube.

[0055] When the quenching tube is fixed between the first ejector pin 21 and the second ejector pin 22, the eighth servo drive assembly drives the moving block 253 to move along the first track, and the seventh servo drive assembly drives the moving block 253 to move along the second track, so that the moving block 253 drives the first probe 251 to approach the quenching tube and move along the length direction of the quenching tube, thereby achieving the peripheral surface detection of quenching tubes with different outer diameters or quenching tubes with changing outer diameters.

The rotating shaft 64 passes through the two fixed supports 63. Two connecting blocks 65 are fixed on the rotating shaft 64. The two connecting blocks 65 are respectively fixed on each side of the first discharge plate 11.

[0057] When the piston rod of the second cylinder 61 is extended, the second cylinder 61 drives the rotating block 62 to rotate, the rotating block 62 drives the rotating shaft 64 to rotate, and the rotating shaft 64 drives the first discharge plate 11 to rotate so that the first discharge plate 11 is placed on the first workstation 4, preventing unqualified quenching tubes from falling into the second discharge plate 12. When the second cylinder 61 is reset, the first discharge plate 11 is reset and drives the quenching tubes to be collected into the first discharge plate 11, thereby completing the screening of the quenching tubes.

[0060] When the lengths of the quenching tubes are different, the fifth servo drive unit 16 drives the reference ejector seat 231 to move to adjust the distance between the reference ejector seat 231 and the floating ejector seat 232, so that the distance between the reference ejector seat 231 and the floating ejector seat 232 matches the length of the quenching tube, and then starts the fourth servo drive unit 15 to drive the reference plate 14 to move, adjust the distance between the two groups of supporting plates 3, and finally starts the sixth servo drive unit 17 to adjust the distance between the two support plates 242, so that quenching tubes of different lengths can be detected.

[0070] The implementation principle of the embodiment of the present application is: the quenching tube is placed on a fixed supporting plate 3, and then the movable supporting plate 3 transfers the quenching tube to the second workstation 5 by repeatedly moving up and down, the third servo drive unit 53 drives the movable support 52 to move, and the second probe 54 is inserted into the quenching tube to perform flaw detection on the inside of the quenching tube.

[0071] If the internal flaw detection of the quenching tube fails after inspection, the second cylinder 61 drives the rotating block 62 to rotate, so that the first discharge plate 11 is placed on the first work station 4, and then the movable supporting plate 3 continues to rise and fall to transfer the quenching tube to the first work station 4, and then the first work station 4 is first lifted and then lowered so that the quenching tube is located in the support groove 246, and then the first work station 4 is lifted again, so that the quenching tube is separated from the support groove 246 and slides into the first discharge plate 11 along the top surface of the first work station 4, and then the second cylinder 61 drives the first discharge plate 11 to reset, completing the collection of unqualified quenching tubes.

[0072] If the internal flaw detection of the quenching tube is qualified after the detection, the quenching tube is further transferred to the first workstation 4, and then the first workstation 4 is lifted and then lowered so that the quenching tube is located in the support groove 246, and then the second servo drive unit 245 lifts the lifting plate 243, and the lifting plate 243 drives the workstation plate 241 and the support plate 242 to move upward so that the quenching tube rises and aligns with the first ejector pin 21 and the second ejector pin 22, and then the first servo drive unit 234 drives the floating ejector seat 232 to move so that the first ejector pin 21 and the second ejector pin 22 fix the quenching tube, and the motor 233 drives the second ejector pin 22 to drive the quenching tube to rotate, and the eighth servo drive unit drives the moving block 253 to slide along the Z direction, and the seventh servo drive unit drives the sliding block 254 to slide along the X direction, so that the first probe 251 is close to the outer surface of the quenching tube for peripheral flaw detection;

[0073] When the eddy current flaw detection of the quenching tube fails, the first discharge plate 11 is placed on the first station 4 again, the first ejector pin 21 and the second ejector pin 22 are released to fix the quenching tube, the support plate 242 is lowered to separate the quenching tube from the support groove 246, and then the quenching tube slides into the first discharge plate 11 along the top surface of the first station 4; when the eddy current flaw detection of the quenching tube passes, the support plate 242 separates the quenching tube from the support groove 246 and then directly slides into the second discharge plate 12 along the top surface of the first station 4. The support plate 3 allows the quenching tubes to move forward one by one without interfering with each other, and replaces manual grabbing, so that the quenching tubes can be transported to the detection device 2 and automatically detach from the detection device 2 and complete the screening of the quenching tubes, thereby improving the detection efficiency.
