Description

Technical Field

[0001] This invention belongs to the technical field of steel pipe conveying devices, specifically relating to a feeding device and method for steel pipe flaw detection equipment. Background Technology

[0002] With the rapid development of the electric vehicle industry, precision steel pipes are widely used as core structural materials in key components such as the vehicle frame structure, chassis support, battery pack protective frame, and high-pressure pipeline protective sleeve. The quality and flaw detection accuracy of these steel pipes are directly related to the structural strength, driving safety, and service life of the entire electric vehicle. Therefore, higher standardization and automation requirements are put forward for the non-destructive testing of steel pipes.

[0003] Existing steel pipe flaw detection equipment typically employs multiple sets of transverse rollers and multiple sets of longitudinal rollers in its feeding device. This allows the steel pipe to be conveyed linearly to the flaw detection equipment before rotation, enabling circumferential inspection. However, this traditional structure is only suitable for steel pipes with larger diameters. When dealing with small-diameter precision steel pipes used in electric vehicle components, the limited space around the pipe makes it difficult to arrange multiple sets of motors and longitudinal roller assemblies to drive the pipe's rotation. This results in problems such as complex structure, poor adaptability, difficulty in balancing feeding and rotation of small-diameter steel pipes, low flaw detection efficiency, and incomplete inspection coverage. Consequently, it fails to meet the production requirements of the electric vehicle industry for efficient and high-precision flaw detection of small-diameter steel pipes. Summary of the Invention

[0004] The purpose of this invention is to provide a feeding device with a simple structure and reasonable design in order to solve the above problems.

The transport bushing is provided with a clamping assembly for fixing the steel pipe. The transport bushing is rotatably connected to the drive end of the transverse conveying assembly and connected to the drive end of the rotary conveying assembly. While two sets of transverse conveying components alternately convey steel pipes in a straight line through corresponding transport bushings, one set of rotary conveying components works with the corresponding transverse conveying components to drive the steel pipe to rotate, thereby conveying the steel pipe spirally into the flaw detection mechanism. The rotary conveying assembly includes a drive rail, an elastic element, and a slider connected to one end of the elastic element. The other end of the elastic element is connected to the surface of the transport bushing. The drive rail includes a spiral rail portion sleeved on the outside of the transport bushing. Both ends of the spiral rail portion are connected to a straight rail portion. An adjustable block that can move up and down is provided below the straight rail portion to guide the slider to move from the straight rail portion to the spiral rail portion, thereby driving the steel pipe inside the transport bushing to rotate.

[0006] As a further optimization of the present invention, a guide tube is fixedly connected to the end of the transport bushing away from the flaw detection mechanism, and the guide tube is arranged in a trumpet shape.

[0007] As a further optimization of the present invention, the drive track further includes an outer sleeve and an arc-shaped block.

The arc-shaped block is correspondingly arranged at one end of the spiral rail near the inclined groove.

[0008] As a further optimization of the present invention, the elastic element is an elastic telescopic rod, and a driving element for driving the adjustment block to move up and down is connected to the worktable.

[0009] As a further optimization of the present invention, the upper surface of the adjusting block is provided with inclined groove 1 and inclined groove 2 at the two ends corresponding to the straight rail part. The groove wall of inclined groove 1 is provided with an upward inclined surface 1, so that the slider sliding from the spiral rail part into the straight rail part is lifted up. The groove wall of inclined groove 2 is provided with an inclined surface 2 that is inclined towards the spiral rail part, so as to guide the slider to slide from the straight rail part into the spiral rail part.

[0010] As a further optimization of the present invention, the transverse conveying assembly includes a support plate, a first transmission rod, a second transmission rod, and a transmission plate. The support plate is fixedly connected to the surface of the workbench. Two sets of the first and second transmission rods are provided and arranged in parallel. One end of the first transmission rod is rotatably connected to the surface of the support plate, and the other end is rotatably connected to the surface of the transmission plate. A mounting sleeve is rotatably connected to the surface of the transport bushing, and a fixing plate is fixedly connected to the surface of the mounting sleeve. One end of the second transmission rod is rotatably connected to the surface of the fixing plate, and the other end is rotatably connected to the surface of the transmission plate. A transmission gear is fixedly connected to the end of each set of the first and second transmission rods near the second transmission rod, and the two sets of transmission gears mesh with each other. A second driving component is rotatably connected to the surface of the support plate, and the driving end of the second driving component is rotatably connected to the second transmission rod.

[0011] As a further optimization of the present invention, the clamping assembly includes an outer ring sleeve, an inner ring sleeve, a driving component three, and multiple sets of pressure plates. The inner ring sleeve is fitted onto the outer surface of the transport shaft sleeve, and the outer ring sleeve is fitted onto the outer surface of the inner ring sleeve and fixedly connected to the driving end of the driving component three. The surface of the transport shaft sleeve has multiple sets of circumferentially arranged clamping grooves, and the multiple sets of pressure plates are slidably connected in the corresponding clamping grooves. The surface of each set of pressure plates has a sliding groove, which is inclined. The inner ring sleeve is provided with multiple sets of control blocks, which are slidably connected in the corresponding sliding grooves. The driving component three is connected to a fixed plate.

[0012] As a further optimization of the present invention, the inner ring sleeve includes a ring sleeve portion and multiple sets of ring plate portions arranged circumferentially along the surface of the ring sleeve portion. The ring sleeve portion is sleeved on the outer surface of the transport bushing, and the outer ring sleeve is sleeved on the outer surface of the ring sleeve portion. One end of the ring plate portion is connected to the surface of the ring sleeve portion, and each set of control blocks is correspondingly connected between adjacent ring plate portions.

[0013] A second aspect of the present invention provides a method for feeding a steel pipe flaw detection device, using the aforementioned steel pipe flaw detection device feeding apparatus, comprising the following steps: S1. Insert the steel pipe into the two sets of transport bushings in sequence, and fix the steel pipe in the corresponding transport bushing with the first set of clamping components. S2. Next, start the first set of transverse conveying components to drive the steel pipe to be fed into the flaw detection mechanism in a straight line. At the same time, start the corresponding rotary conveying components so that the corresponding transport bushing drives the steel pipe to rotate synchronously. S3. After the steel pipe is rotated, the second set of clamping components clamps the steel pipe, and the first set of clamping components releases the steel pipe. S4. Next, the first set of transverse conveying components drives the corresponding transport bushing to reset. After the reset is completed, the first set of clamping components re-clamps the steel pipe, and the second set of clamping components releases the steel pipe. S5. Repeat S2 to S4 to achieve alternating conveying and rotating flaw detection of steel pipes. If the steel pipes need to rotate in the opposite direction, switch to the second set of rotating conveying components.

[0014] The beneficial effects of this invention are as follows: This invention breaks through the limitations of traditional roller assembly structures, eliminating the need to arrange multiple sets of drive motors and longitudinal rollers on the outer periphery of the steel pipe, and can perfectly adapt to the feeding and rotary flaw detection requirements of small-diameter precision steel pipes for electric vehicles; Through the coordinated cooperation of rotary conveying components, transverse conveying components and clamping components, this invention has a simplified overall structure, fewer parts, convenient installation and maintenance, and reduces equipment manufacturing costs and failure rates.

[0017] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0018] Example 1 refer to Figures 1 to 3 The structure shown is a feeding device for a steel pipe flaw detection equipment, including a workbench 1 and a flaw detection mechanism 2 disposed on the surface of the workbench 1. Two sets of conveying mechanisms are installed on the workbench 1. The conveying mechanism includes a transport bushing 3, a transverse conveying assembly 4, and a rotary conveying assembly 5. The transport bushing 3 is provided with a clamping assembly 6 for fixing the steel pipe. The transport bushing 3 is rotatably connected to the drive end of the transverse conveying assembly 4 and connected to the drive end of the rotary conveying assembly 5. While the two sets of transverse conveying components 4 alternately convey steel pipes in a straight line through the corresponding transport bushings 3, one set of rotating conveying components 5 cooperates with the corresponding transverse conveying components 4 to drive the steel pipe to rotate, thereby spirally conveying the steel pipe into the flaw detection mechanism 2. The rotary conveying assembly 5 includes a drive rail 53, an elastic element 51, and a slider 52 connected to one end of the elastic element 51. The other end of the elastic element 51 is connected to the surface of the transport sleeve 3. The drive rail 53 includes a spiral rail portion 532 sleeved on the outside of the transport sleeve 3. Both ends of the spiral rail portion 532 are connected to a straight rail portion 533. An adjustable block 54 that can move up and down is provided below the straight rail portion 533 to guide the slider 52 to move from the straight rail portion 533 to the spiral rail portion 532, thereby driving the steel pipe inside the transport sleeve 3 to rotate.

[0019] In this embodiment, two sets of conveying mechanisms are installed on both sides of the workbench 1 and arranged in a front-to-back manner along the length of the workbench 1, so that the central axis of the two sets of transport bushings 3 is on the same straight line as the central axis of the detection port of the flaw detection mechanism 2; the transverse conveying assembly 4 drives the steel pipe to move in a straight line through the transport bushings 3, so that the steel pipe gradually approaches the flaw detection mechanism 2. However, in the initial state, the driving ends of the two sets of transverse conveying assemblies 4 with transport bushings 3 are located at the end away from the flaw detection mechanism 2.

[0020] It should be noted that for steel pipes with smaller diameters, the limited outer space makes it difficult to arrange multiple sets of motors to drive the longitudinal roller assembly and thus rotate the steel pipe. Furthermore, existing structures using multiple sets of transverse rollers and multiple sets of longitudinal rollers to drive the linear movement and rotation of the steel pipe, respectively, are difficult to operate simultaneously. In contrast, the rotary conveying assembly in the feeding device of this embodiment is not a separate mechanical structure for driving the rotation of the steel pipe. It works in conjunction with the transverse rollers to achieve composite feeding of linear conveying and synchronous rotation of the steel pipe, or it can achieve linear conveying independently, meeting the requirements of different flaw detection processes and providing more comprehensive flaw detection coverage. Moreover, the two conveying mechanisms work alternately, ensuring firm clamping of the steel pipe, smooth conveying, and precise control of the rotation angle, effectively improving the flaw detection efficiency and inspection accuracy of the steel pipe, and adapting to the mass production inspection needs of electric vehicle parts.

[0021] In actual use, the steel pipe rotates while moving in a straight line, forming a spiral motion trajectory. This motion mode allows the probe in the flaw detection equipment to continuously scan along the surface of the steel pipe, which is equivalent to the probe performing a "spiral" scan on the steel pipe, thereby ensuring that longitudinal and transverse defects and wall thickness changes on the inner and outer walls of the steel pipe are completely detected.

[0022] In this embodiment, multiple flaw detection mechanisms 2 arranged in a straight line can be set up. Since the flaw detection mechanism 2 is an existing mechanism, it will not be described in detail in this embodiment.

[0023] Furthermore, a guide tube 7 is fixedly connected to the end of the transport bushing 3 away from the flaw detection mechanism 2, and the guide tube 7 is arranged in a trumpet shape.

[0024] It should be noted that the guide tube 7 is designed in a trumpet shape to facilitate the insertion of the steel pipe into the transport sleeve 3. In actual use, when the steel pipe needs to be inspected, the steel pipe is first inserted into the two sets of transport sleeves 3 sequentially from the side away from the flaw detection mechanism 2. Then, the clamping assembly 6 near the flaw detection mechanism 2 fixes (clamps) the steel pipe in the corresponding transport sleeve 3. Then, the transverse conveying assembly 4 near the flaw detection mechanism 2 drives the steel pipe fixed in the transport sleeve 3 to move linearly into the flaw detection mechanism 2. During this process, the rotary conveying assembly 5 near the flaw detection mechanism 2 drives the transport sleeve 3 to rotate and drives the steel pipe to rotate. After the steel pipe finishes rotating, the clamping assembly 6 away from the flaw detection mechanism 2 clamps the surface of the steel pipe in the corresponding transport sleeve 3. When the clamping assembly 6 near the flaw detection mechanism 2 releases the steel pipe, the transverse conveying assembly 4 near the flaw detection mechanism 2 only drives the corresponding transport sleeve 3 to reset. After reset, the clamping assembly 6 near the flaw detection mechanism 2 continues to clamp the steel pipe, while another set of clamping assemblies 6 releases the steel pipe. The transverse conveying assembly 4 near the flaw detection mechanism 2, in conjunction with the rotary conveying assembly 5, drives the steel pipe to be linearly conveyed into the flaw detection mechanism 2 while rotating. If the steel pipe needs to rotate in the opposite direction, the transverse conveying assembly 4, the rotary conveying assembly 5, the clamping assembly 6, and the clamping assembly 6 near the flaw detection mechanism 2 can be operated in coordination to achieve this. This invention enables the flaw detection mechanism 2 to detect a wider range of steel pipe surfaces through spiral feeding.

[0025] It should be further explained that when the steel pipe needs to move only in a straight line, the steel pipe can also move only in a straight line by alternating the two sets of transverse conveying components 4 and the corresponding clamping components 6, without activating the rotary conveying mechanism 5 during this process.

[0026] refer to Figure 2 and Figure 3 As shown in the partial structure, the drive track 53 also includes an outer sleeve portion 531 and an arc-shaped block 534. The outer sleeve portion 531 is sleeved on the outside of the transport bushing 3. The spiral rail portion 532 is connected to the inner wall of the outer sleeve portion 531. The surface of the outer sleeve portion 531 has a groove corresponding to the straight rail portion 533. The outer surface of the outer sleeve portion 531 is fixedly connected to a mounting plate 8, which is fixedly connected to the surface of the worktable 1. The surface of the outer sleeve portion 531 is also provided with a mounting groove. The arc-shaped block 534 is fixedly connected in the mounting groove. The arc-shaped block 534 is correspondingly set at one end of the spiral rail portion 532 near the inclined groove 542.

[0027] Furthermore, the elastic element 51 is an elastic telescopic rod, and the worktable 1 is connected to a drive element 55 for driving the adjustment block 54 to move up and down.

[0028] Among them, the driving component 55 is an electric push rod, hydraulic cylinder, pneumatic cylinder, etc.; it should be noted that the driving component 55 can drive the adjusting block 54 to move up and down to move closer to or away from the straight rail 533.

[0029] Furthermore, the upper surface of the adjusting block 54 is provided with inclined groove 1 541 and inclined groove 2 542 at the two ends corresponding to the straight rail part 533. The groove wall of inclined groove 1 541 is provided with an upward inclined surface 1, which lifts up the slider 52 that slides from the spiral rail part 532 into the straight rail part 533. The groove wall of inclined groove 2 542 is provided with an inclined surface 2 that is inclined towards the spiral rail part 532, so as to guide the slider 52 to slide from the straight rail part 533 into the spiral rail part 532.

[0030] In the initial state, the slider 52 is positioned within the straight rail section 533, corresponding to the inclined chute 542; the adjusting block 54 is positioned away from the straight rail section 533; and the elastic telescopic rod is in a free state. When it is necessary for the steel pipe to rotate during linear conveying, the drive component 55 is activated to move the adjusting block 54 upwards, positioning the slider 52 within the inclined chute 542. At this time, during the linear movement of the steel pipe driven by the transverse conveying assembly 4, the slider 52 enters the spiral rail section 532 due to the guidance of the inclined surface 2 of the inclined chute 542. Simultaneously, with the cooperation of the arc block 534, the elastic telescopic rod is compressed, and the slider 52 slides along the spiral rail section 532, causing the transport bushing 3 to rotate the steel pipe until the slider 52 slides into the other end of the spiral rail section 532 and enters the inclined chute 541 (at which point the steel pipe has rotated one revolution). At this point, the elastic telescopic rod is in a free state, allowing the slider 52 to enter the inclined chute 541. Guided by the inclined plane, the slider 52 moves along the inner wall of the straight rail 533 and the upper surface of the adjusting block 54. Then, the clamping assembly 6 releases the steel pipe, and the transverse conveying assembly 4 can drive the transport sleeve 3 to reset. When the slider 52 slides along the spiral rail 532 and moves along the upper surface of the adjusting block 54, the elastic telescopic rod is always in a compressed state. When sliding in the spiral rail 532, the end of the slider 52 away from the elastic telescopic rod is pressed against the inner wall of the outer sleeve 531. The elastic telescopic rod is only in a free state when the slider 52 is located in the inclined groove 541 and the inclined groove 542. If it is necessary for the steel pipe to move only in a straight line, the drive unit 55 is activated to drive the corresponding adjusting block 54 away from the corresponding straight rail 533. At this time, the slider 52 will only move in the straight rail 533 and will not enter the spiral rail 532. When the slider 52 moves in the straight rail 533, the elastic telescopic rod is always in a free state.

[0031] The specific structure of inclined slot 2 542 is as follows: Figure 4 As shown, Figure 4 The dotted line with the arrow in the middle represents the running path of slider 52, which is guided by inclined plane 2 from straight rail section 533 into spiral rail section 532.

[0032] It should be noted that the inner bottom surface of the inclined groove 541 is lower than the upper surface of the adjusting block 54.

[0033] refer to Figure 5 and Figure 6 The structure shown includes a transverse conveying assembly 4 comprising a support plate 41, a first transmission rod 42, a second transmission rod 43, and a transmission plate 44. The support plate 41 is fixedly connected to the surface of the workbench 1. Two sets of first transmission rods 42 and second transmission rods 43 are provided and arranged in parallel. One end of the first transmission rod 42 is rotatably connected to the surface of the support plate 41, and the other end is rotatably connected to the surface of the transmission plate 44. A mounting sleeve 47 is rotatably connected to the surface of the transport bushing 3, and a fixing plate 48 is fixedly connected to the surface of the mounting sleeve 47. One end of the second transmission rod 43 is rotatably connected to the surface of the fixing plate 48, and the other end is rotatably connected to the surface of the transmission plate 44. One set of first transmission rods 42 and second transmission rods 43 are both fixedly connected to a transmission gear 46 near the end of the second transmission rod 43. The two sets of transmission gears 46 mesh with each other. A second driving member 45 is rotatably connected to the surface of the support plate 41, and the driving end of the second driving member 45 is rotatably connected to the second transmission rod 43.

[0034] Among them, the second driving component 45 is an electric push rod, hydraulic cylinder, pneumatic cylinder, etc. In actual use, the second driving component 45 is started to drive the transmission rod 42 to move. With the cooperation of the two sets of transmission gears 46, the transmission rod 43 moves, thereby driving the transport bushing 3 to move in a straight line.

[0035] It should be noted that the transport bushing 3 is provided with limit rings on the surfaces of the mounting cylinder 47 on both sides to restrict the movement of the mounting cylinder 47, so that the mounting cylinder 47 can only rotate along the surface of the transport bushing 3.

[0036] refer to Figure 7 and Figure 8 The structure shown includes a clamping assembly 6 comprising an outer ring sleeve 61, an inner ring sleeve 62, a driving component 63, and multiple sets of pressure plates 64. The inner ring sleeve 62 is fitted onto the outer surface of the transport bushing 3, and the outer ring sleeve 61 is fitted onto the outer surface of the inner ring sleeve 62 and fixedly connected to the driving end of the driving component 63. The surface of the transport bushing 3 has multiple sets of circumferentially arranged clamping grooves 65, and the multiple sets of pressure plates 64 are slidably connected in the corresponding clamping grooves 65. Each set of pressure plates 64 has a sliding groove 66 on its surface, and the sliding groove 66 is inclined. The inner ring sleeve 62 is provided with multiple sets of control blocks 67, and the multiple sets of control blocks 67 are slidably connected in the corresponding sliding grooves 66. The driving component 63 is connected to the fixed plate 48.

[0037] Among them, the driving component 63 can be any kind of mechanical structure that can drive the outer ring sleeve 61 to move in a linear motion. Specifically, it can be an electric push rod, a hydraulic cylinder, a pneumatic cylinder, etc.

[0038] It should be noted that a rubber pad can be installed at the part where the pressure plate 64 contacts the steel pipe to prevent hard contact between the pressure plate 64 and the steel pipe.

[0039] Furthermore, the inner ring sleeve 62 includes a ring sleeve portion 621 and multiple sets of ring plate portions 622 arranged circumferentially along the surface of the ring sleeve portion 621. The ring sleeve portion 621 is sleeved on the outer surface of the transport bushing 3, and the outer ring sleeve 61 is sleeved on the outer surface of the ring sleeve portion 621. One end of the ring plate portion 622 is connected to the surface of the ring sleeve portion 621, and each set of control blocks 67 is correspondingly connected between adjacent ring plate portions 622.

[0040] In actual use, after the steel pipe is inserted into the transport sleeve 3 from the guide cylinder 7, the drive unit 63 is activated to drive the outer ring sleeve 61 to move. The outer ring sleeve 61 drives the ring part 621 and the ring plate part 622 connected to the ring part 621 to move along the outer surface of the transport sleeve 3, thereby causing the control block 67 to drive multiple sets of pressure plates 64 to slide along the inner wall of the clamping groove 65 until the multiple sets of pressure plates 64 press against the surface of the steel pipe to fix the steel pipe.

[0041] Example 2; A method for feeding steel pipe flaw detection equipment, using the steel pipe flaw detection equipment feeding device described in Example 1, includes the following steps: S1. Insert the steel pipe into the two sets of transport bushings 3 in sequence, and fix the steel pipe in the corresponding transport bushing 3 by the first set of clamping components 6. S2. Next, start the first set of transverse conveying components 4 to drive the steel pipe to be fed into the flaw detection mechanism 2 in a straight line. At the same time, start the corresponding rotary conveying components 5 so that the corresponding transport bushing 3 drives the steel pipe to rotate synchronously. S3. After the steel pipe is rotated, the second set of clamping components 6 clamps the steel pipe, and the first set of clamping components 6 releases the steel pipe. S4. Next, the first set of transverse conveying components 4 drives the corresponding transport sleeve 3 to reset. After the reset is completed, the first set of clamping components 6 re-clamps the steel pipe, and the second set of clamping components 6 releases the steel pipe. S5. Repeat S2 to S4 to achieve alternating conveying and rotating flaw detection of steel pipes. If the steel pipes need to rotate in the opposite direction, switch to the second set of rotating conveying components 5.

[0042] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
