Description

TECHNICAL FIELD

[0001] The application belongs to the technical field related to nondestructive testing, and particularly relates to a metal cylinder segment surface coating nondestructive testing device. BACKGROUND

[0002] For the purposes of protection, insulation, decoration and the like, the surfaces of most metals are attached with thick or thin coatings in the application process. In order to ensure that the surface coating of the metal cylinder segment is free of defects such as delamination, slag inclusion and air entrapment, the surface coating of the metal cylinder segment needs to be subjected to nondestructive testing. The nondestructive testing equipment on the market is mostly handheld, and the detection probe needs to be manually placed in the area to be detected for detection, thereby causing many problems.

[0003] 1. When the area of the product to be detected is large or the number of products is large, manual detection is slow and inefficient.

[0004] 2. The consistency of the detection results of the same product cannot be guaranteed, and is completely dependent on the detection experience of the operator.

[0005] 3. After one product is detected, the workpiece on the detection station needs to be manually replaced and fixed, and the replacement cycle is long.

[0006] 4. During manual detection, the detection path is not accurate, and problems such as multiple detections of the same area or missed detection of part of the area may exist. SUMMARY

[0007] The purpose of the present application is to provide a metal cylinder segment surface coating nondestructive testing device to overcome the above problems.

[0008] A metal cylinder segment surface coating nondestructive testing device, characterized in that it comprises a Z-direction lifting mechanism 12, an X-direction adjusting mechanism 14, a rotary material changing mechanism 8, an ultrasonic detection probe assembly 4, a control electric cabinet 10 and a profile frame 16; the profile frame 16 has a base 162 and a vertical frame 161; the rotary material changing mechanism 8 is installed on the middle of the upper surface of the base 162; the X-direction adjusting mechanism 14 is installed on the horizontal plane of the upper surface of the vertical frame 161; the Z-direction lifting mechanism 12 is installed on the X-direction adjusting mechanism 14; the ultrasonic detection probe assembly 4 is installed on the lifting bracket 2 of the Z-direction lifting mechanism 12; and the control electric cabinet 10 is installed outside the vertical frame 161.

[0009] The Z-direction lifting mechanism 12 comprises a servo motor I 13, a linear module 31, a linear module sliding seat 32, a sliding table 37 and a lifting bracket 2; the servo motor I 13 is installed on the top end surface of the linear module 31; the lifting bracket 2 is connected to the linear module 31 through the linear module sliding seat 32; the movement of the linear module sliding seat 32 can drive the lifting bracket 2 to realize the lifting function; and the sliding table 37 is connected to the lower end of the linear module 31.

[0010] The X-axis adjustment mechanism 14 is installed on the vertical frame 161 of the profile frame 16. By rotating the X-axis adjustment handwheel 15 of the X-axis adjustment mechanism 14, the slide table 37 is driven to move horizontally, thereby driving the Z-axis lifting mechanism 12 to move synchronously.

[0011] The rotary material changing mechanism 8 includes a rotary platform 24, two pneumatic clamping chuck mechanisms 18, and a workpiece rotation driving mechanism 21. The two pneumatic clamping chuck mechanisms 18 are mounted on the rotary platform 24. The rotary platform 24 is controlled to rotate by a servo motor II 23. The rotary platform 24 designates the position of the pneumatic clamping chuck mechanism 18 near the vertical frame 161 as the inspection station 6, and the position of the other pneumatic clamping chuck mechanism 18 as the inspection station 7. Each pneumatic clamping chuck mechanism 18 is equipped with a clamping block 17, and the lower part of the pneumatic clamping chuck mechanism 18 is equipped with an outer... A toothed rotary support bearing 19 is provided; a workpiece rotation driving mechanism 21 is also provided on the base 161 next to the inspection station 6. The workpiece rotation driving mechanism 21 is provided with a drive gear 20, which is connected to the external toothed rotary support bearing 19 of the pneumatic clamping chuck mechanism 18 at the inspection station 6. The workpiece rotation driving mechanism 21 drives the drive gear 20 at its top to rotate through the control of the servo motor Ⅲ 22. The drive gear 20 then drives the external toothed rotary support bearing 19 to rotate. The external toothed rotary support bearing 19 then drives the entire pneumatic clamping chuck mechanism 18 to rotate.

[0012] The control cabinet 10 is used to control the movement of servo motor I, servo motor II and servo motor III, as well as the opening and closing of the pneumatic clamping chuck 18, so as to realize the linkage and cooperation of various motion mechanisms to complete the workpiece switching between the detection station 6 and the workpiece to be detected station 7 in the detection area; and to process the data transmitted back by the ultrasonic detection probe 4.

[0013] During operation, the rotating platform 24 is controlled by the servo motor II 23 to rotate 180° every set time. When one of the pneumatic clamping chuck mechanisms 18 enters the inspection station 6, the external tooth rotary support bearing 19 on the pneumatic clamping chuck mechanism 18 engages with the drive gear 20 on the drive workpiece rotation mechanism 21 to achieve power connection; thus completing the replacement of the inspection workpiece 100 on the inspection station 6 with the inspection workpiece 200 on the inspection station 7.

[0014] The Z-axis lifting mechanism 12 includes a linear module 31 and a lifting bracket 2.

The height and direction of probe group A and probe group B are adjusted via the probe spacing adjustment block 5 according to the height and diameter of the workpiece 100 being tested.

[0015] The ultrasonic testing probe assembly 4 can be adjusted laterally in the horizontal direction by rotating the X-axis adjustment handwheel 15.

[0016] The rotary material changing mechanism 21 can switch between the reciprocating rotation of the workpiece 100 to be inspected and the workpiece 200 to be inspected, so that the preparation work of the workpiece 200 to be inspected can be completed during the workpiece inspection process.

[0017] The power transmission method on the pneumatic clamping chuck mechanism 18 is that the external tooth rotary support bearing 19 engages with the drive gear 20 on the drive workpiece rotation mechanism 21. During the rotation material changing process, the rotary material changing mechanism 8 completes the power connection of the pneumatic clamping chuck mechanism 18 entering the inspection station 6 and disengages the power of the pneumatic clamping chuck mechanism 18 leaving the inspection station 6.

[0018] The pneumatic clamping chuck mechanism 18 can rotate along its axis, causing the clamped workpiece 100 to rotate.

[0019] The pneumatic clamping chuck 18 is released and clamped by the opening and closing of the solenoid valve, which controls the rotation of the rotary material changing mechanism 8. During the rotary material changing process, the workpiece 100 being inspected is automatically clamped, fixed and released. The clamping blocks are matched and replaced according to the diameter of the workpiece 100 being inspected.

[0020] The beneficial effects of this invention compared to existing technologies are as follows: This invention proposes a non-destructive testing device for the surface coating of metal cylinder sections, achieving non-destructive testing of the surface coating of metal cylinder sections. The Z-axis lifting mechanism enables axial scanning of the surface coating of the metal cylinder section; the workpiece rotation mechanism drives the workpiece rotation, enabling circumferential scanning of the surface coating; the linkage between the Z-axis lifting mechanism and the workpiece rotation mechanism enables automatic overall scanning of the surface coating of the metal cylinder section; the rotary material changing mechanism enables switching of the workpiece between the testing and inspection stations, allowing the workpiece at the inspection station to be replaced during scanning, while waiting for inspection; the pneumatic clamping chuck mechanism enables automatic clamping and releasing of the workpiece; the linkage between the rotary material changing mechanism and the pneumatic clamping chuck mechanism enables automatic replacement and fixing of the workpiece; and by adjusting the lifting frame of the Z-axis lifting mechanism and the clamping blocks on the pneumatic clamping chuck mechanism, non-destructive testing of surface coatings of metal cylinder sections with different diameters and heights can be achieved. By scanning with two sets of ultrasonic probes simultaneously, the detection rate can be doubled. Attached Figure Description

[0032] The Z-axis lifting mechanism is installed on the X-axis adjusting mechanism. It controls the movement of the linear module through servo motor I, thereby driving the lifting bracket to achieve the lifting function.

[0033] The X-axis adjustment mechanism is installed on the profile frame. By rotating the X-axis adjustment handwheel, the slide table is driven to move horizontally, which in turn drives the Z-axis lifting mechanism to move synchronously, thereby realizing the horizontal adjustment of the ultrasonic detection probe.

[0034] The rotary material changing mechanism is installed on the profile frame. The rotary platform is controlled to rotate 180° by a servo motor II to realize the replacement of the workpiece at the inspection station with the workpiece at the inspection station.

[0035] The pneumatic clamping chuck mechanism consists of two sets, both mounted on the rotary material changing mechanism.

[0042] To make the objectives, technical solutions, and advantages of this invention more readily understood, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] The detection device includes: such as Figure 1 As shown, the Z-axis lifting mechanism 12 is mounted on the X-axis adjusting mechanism 14. It controls the movement of the linear module via the servo motor I 13, thereby driving the lifting bracket 11 to achieve the lifting function. Figure 2 As shown, the X-axis adjustment mechanism 14 is mounted on the profile frame 16. By rotating the X-axis adjustment handwheel 15, the slide table is driven to move horizontally, which in turn drives the Z-axis lifting mechanism 12 to move synchronously, thereby realizing the horizontal adjustment of the ultrasonic testing probe 4; Figure 1 As shown, the rotary material changing mechanism 8 is mounted on the profile frame 16. It controls the rotary platform 24 to rotate 180° via a servo motor II 23, thereby replacing the workpiece at the inspection station with the workpiece at the inspection station. Figure 3The pneumatic clamping chuck mechanism 18 shown consists of two sets, both mounted on the rotary material changing mechanism 8. Through the external toothed rotary support bearing 19 in the pneumatic clamping chuck mechanism 18, the pneumatic clamping chuck mechanism 18 can rotate along its axis, driving the clamped workpiece to rotate. The clamping block 17 can be matched and replaced according to the inner diameter of the workpiece; for example... Figure 1 As shown, the workpiece rotation mechanism 21 is mounted on the profile frame 16 and is controlled by a servo motor III 22 to rotate the drive gear 20 at its top. Figure 3 As shown, when one of the pneumatic clamping chuck mechanisms 18 enters the inspection station 6, the external tooth rotary support bearing 19 on the pneumatic clamping chuck mechanism 18 engages with the drive gear 20 on the workpiece rotation driving mechanism 21, realizing a power connection; as Figure 1 As shown, the ultrasonic testing probe assembly 4 is mounted on the lifting bracket 2 of the Z-axis lifting mechanism 12. Two sets work together, one above the other, doubling the testing efficiency. Figure 1 As shown, the control cabinet 10 is installed on the side of the profile frame 16; it is used to control the movement of servo motor I 13, servo motor II 23, and servo motor III 22, and the opening and closing of the pneumatic clamping chuck, so as to realize the linkage and cooperation of each motion mechanism to complete the scanning of the detection area and the switching of the workpiece between the detection station 6 and the workpiece to be detected station 7, and to process the data returned by the ultrasonic detection probe; the profile frame 16 is used for the installation and fixation of each mechanism.

[0044] The working principle of this invention for a non-destructive testing device for surface coatings of metal cylinder sections is as follows:

[0045] Before testing, make adaptive adjustments according to the workpiece to be tested: the clamping block can be matched and replaced according to the workpiece size. Rotate the X-axis adjustment handwheel 15 to drive the slide table to move horizontally, and drive the Z-axis lifting mechanism 12 to move synchronously, so that the axis of the ultrasonic testing probe assembly 4 is in the same plane as the axis of the testing station 6; rotate the four Y-axis adjustable handles 1 counterclockwise to allow the two lifting brackets 2 to slide back and forth, so that the ultrasonic testing probes installed on the front bracket and the rear bracket are within 5-10mm of the inner and outer surfaces of the workpiece to be tested, respectively. Rotate the four Y-axis adjustable handles 1 clockwise to fix the two lifting brackets 2; the testing probe can be compatible with workpieces of two height specifications, H1 and H2 (H1>H2), at one time. Loosen the two upper and two lower limit adjustment blocks 11 so that the distance between the lower surface of the upper limit adjustment block 11 and the upper surface of the lower probe spacing adjustment block is H1 / 2, and the distance between the upper surface of the lower limit adjustment block 11 and the lower surface of the lower probe spacing adjustment block is H2 / 2. When inspecting products with a height of H1, place the upper surface of the probe spacing adjustment block 5 against the lower surface of the upper limit adjustment block 11 and tighten the screws to secure it. Similarly, when inspecting products with a height of H2, place the lower surface of the probe spacing adjustment block 5 against the upper surface of the lower limit adjustment block 11. When inspecting workpieces of other sizes, repeat the above steps to readjust the position of the upper or lower limit adjustment block 11.

[0046] The operator places the workpiece to be inspected onto the pneumatic clamping chuck at the inspection station 7. The clamping block 17 can be matched and replaced according to the inner diameter of the workpiece. Click "Change Workpiece" on the touch screen, and the pneumatic clamping chuck mechanism 18 automatically clamps and fixes the workpiece. The rotating material changing mechanism 8 rotates the workpiece to the inspection station and rotates the workpiece that has been inspected at the inspection station 6 to the inspection station 7. After it is in place, the pneumatic clamping chuck mechanism 18 automatically releases the workpiece from the inspection station 7. Click "Start Inspection" on the touch screen, and the Z-axis lifting mechanism 12 drives the two sets of ultrasonic probes 4 to descend to the inspection starting position, and the two sets of ultrasonic probes 4 start scanning. The scanning method is spiral scanning. Simultaneously, the workpiece rotation mechanism 21 drives the workpiece to rotate at a constant speed for one revolution, while the Z-axis lifting mechanism 12 drives the two sets of ultrasonic probes 4 to descend at a constant speed a distance k. After n revolutions, the scanning is completed, where H / 2 = n*k; where H is the current height of the workpiece being inspected. During the scanning process, the operator can remove the inspected workpiece from the inspection station 7 and replace it with the next workpiece to be inspected. After the inspection is completed, the Z-axis lifting mechanism 12 automatically lifts the two sets of ultrasonic probes 4 to the standby position. The rotating material changing mechanism 8 rotates 180° again, and the inspected workpiece is switched from the inspection station 7 to the inspection station. At this point, the inspection process for a single workpiece is complete, and the inspection data and image results are saved to the computer hard drive inside the control cabinet box 10. The scanned image results are as follows: Figure 4As shown, no obvious defects were found; if obvious defects are found, the defective parts can be located by referring to the scan image results.
