Description

Technical Field

[0001] The present application relates to the field of flaw detection equipment, and in particular to an eddy current flaw detection equipment. Background Art

[0002] Eddy current testing is one of many NDT (non-destructive testing) methods, which uses the basic theory of "electromagnetism" as the basis for conductor detection. The generation of eddy currents originates from a phenomenon called electromagnetic induction. When alternating current is applied to a conductor, such as a copper wire, a magnetic field will be generated in the conductor and in the space surrounding the conductor. Eddy currents are induced currents that flow in a loop. It is called "eddy current" because it is the same as the flow of liquid or gas in a loop around an obstacle. If a conductor is placed in this changing magnetic field, eddy currents will be generated in that conductor, and the eddy currents will also generate their own magnetic fields, which expand as the alternating current increases and disappear as the alternating current decreases. Therefore, when defects appear on the surface or near the surface of the conductor or some properties of the measured metal material change, it will affect the intensity and distribution of the eddy current, so that we can detect the changes in the eddy current through it, and then we can indirectly know the existence of defects inside the conductor and whether the metal properties have changed. Therefore, the eddy current principle can solve the problems of metal material flaw detection (crack, defect inspection), thickness measurement (material or coating thickness measurement), sorting, etc.

[0004] Currently in Figure 1 When inspecting the workpiece shown, manual measurement is generally used, which has low inspection efficiency and is difficult to adapt to the needs of modern large-scale inspection. Summary of the invention

[0005] In order to improve the problem that manual inspection of workpieces is inefficient and difficult to adapt to the needs of modern large-scale inspection, the present application provides an eddy current flaw detection device.

[0008] By adopting the above technical scheme, when inspecting the workpiece, the workpiece is first placed on the end of the inclined track away from the workbench, and the workpiece moves along the length direction of the inclined track under the action of gravity. When the workpiece moves to the crack detection component, the crack detection component is used to perform crack detection on the workpiece. If the detection is unqualified, the first shaving component is used to remove the workpiece. If the detection is qualified, the workpiece continues to move along the inclined track to the hardness detection component, and the hardness detection component is used to perform hardness detection on the workpiece. If the hardness test is qualified, the workpiece is arranged and unloaded by an arranging mechanism. If the hardness test is unqualified, the workpiece is removed by the second shaving component, thereby realizing automatic detection and unloading of the workpiece, with high efficiency, and convenient for adapting to the needs of modern large-scale detection.

At this time, the workpiece is restricted on the inclined track by the limit plate, which is convenient for testing the hardness of the workpiece using a hardness detection probe. When the detection is completed, the second cylinder is used to pull the limit plate away from the inclined track, so that the workpiece moves along the length direction of the inclined track under the action of gravity, thereby realizing the hardness detection of the workpiece.

[0015] In a specific possible implementation scheme, the second shaving assembly includes a first conveyor for transporting the workpiece, a second shaving plate arranged on the workbench, and a third cylinder arranged on the workbench, the second shaving plate is used to push the workpiece with unqualified hardness away from the first conveyor, and the third cylinder is used to push the second shaving plate along a movement direction perpendicular to the first conveyor.

[0045] Reference Figure 2 , Figure 3 and Figure 4 , taking a set of feeding detection mechanism 2 as an example, the feeding detection mechanism 2 includes a vibration plate 5 and an inclined track 11 fixedly connected to the workbench 1. When the workpiece 10 is inspected, the vibration plate 5 transports the workpiece 10 to be inspected to the inclined track 11, and the workpiece 10 moves from the end of the inclined track 11 away from the workbench 1 to the end of the inclined track 11 close to the workbench 1. The crack detection component 6, the first shaving component 7, the hardness detection component 8 and the second shaving component 9 are sequentially arranged on the workbench 1 along the length direction of the inclined track 11. In this embodiment, the cross section of the inclined track 11 is set to be "L"-shaped, and the workpiece 10 is placed in the inclined track 11 and slides along the length direction of the inclined track 11 under the action of gravity.

The crack detection probe 61 is fixedly connected to the first mounting seat 121. The first screw rod 122 is vertically arranged. Both ends of the first screw rod 122 are rotatably connected to the workbench 1. One end of the first screw rod 122 away from the workbench 1 is transmission-connected to the first motor 123 through a first coupling 13. The first motor 123 is fixedly connected to the workbench 1.

The first mounting seat 121 is provided with a first guide groove 14 for the first guide plate 124 to pass through.

[0047] Reference Figure 4 , Figure 5 and Figure 6The first roller 62 and the second roller 63 are both rotatably connected and arranged on the workbench 1, the axes of the first roller 62 and the second roller 63 are parallel to the axis of the workpiece 10, the distance between the peripheral wall of the first roller 62 and the peripheral wall of the second roller 63 is smaller than the diameter of the workpiece 10, and the peripheral walls of the first roller 62 and the second roller 63 enclose a placement space 25 for placing the workpiece 10, the first roller 62 and the second roller 63 are arranged above the inclined track 11, and the workbench 1 is provided with a second motor 51 for driving the first roller 62 to rotate and a third motor 52 for driving the second roller 63 to rotate, and the first roller 62 and the second roller 63 have the same rotation direction.

[0048] Reference Figure 4 , Figure 5 and Figure 6 A transverse driving assembly 15 is provided on the workbench 1 for driving the first roller 62 to move in a direction away from the second roller 63. The transverse driving assembly 15 includes a fifth motor 151, a second screw rod 152 and a second mounting seat 153 for mounting the first roller 62 and the second motor 51. The fifth motor 151 is fixedly connected to the workbench 1. The fifth motor 151 is transmission-connected by a second coupling 16 and the second screw rod 152. Two groups of limit blocks 17 and limit guide rails 18 for limiting the second mounting seat 153 are provided on the workbench 1. A limit guide groove 19 is provided on the limit block 17 for the limit guide rail 18 to slide through. The extension direction of the limit guide rail 18 is perpendicular to the length direction of the inclined track 11. The second mounting seat 153 is fixedly connected to the side wall of the limit guide rail 18 away from the two limit blocks 17 through the connecting plate 20.

[0049] Reference Figure 4 and Figure 7 The first shaving assembly 7 includes a mounting plate 71 and a first shaving plate 72. In the present embodiment, the length direction of the mounting plate 71 is parallel to the length direction of the inclined track 11. The mounting plate 71 and the end of the inclined track 11 close to the first rotating roller 62 are integrally connected. A through groove 21 is provided on the mounting plate 71 for the first shaving plate 72 to slide through. The length direction of the through groove 21 is parallel to the length direction of the inclined track 11. The sliding direction of the first shaving plate 72 is perpendicular to the mounting plate 71. A dropping space 22 for the workpiece 10 to drop is formed between the mounting plate 71 and the first shaving plate 72. A first cylinder 23 for driving the first shaving plate 72 to slide in the through groove 21 is provided on the workbench 1. A first NG material box 24 for accommodating unqualified workpieces 10 is also provided on the workbench 1.

[0050] When the workpiece 10 is subjected to crack detection, the workpiece 10 falls into the placement space 25, and the second motor 51 and the third motor 52 are started. The workpiece 10 rotates in the same direction driven by the first roller 62 and the second roller 63. At this time, the first motor 123 is driven, and the first motor 123 drives the first screw rod 122 to rotate. The first screw rod 122 and the first mounting seat 121 rotate relative to each other. The first mounting seat 121 moves along the axial direction of the first screw rod 122 under the guidance of the first guide plate 124 until the crack detection probe 61 arranged on the first mounting seat 121 is 0.5-0.7mm away from the peripheral wall of the workpiece 10 to be tested. The workpiece 10 is detected in the circumferential direction, which is conducive to achieving a good detection effect.

[0051] When the detection is completed, the fifth motor 151 is started, and the fifth motor 151 drives the second screw rod 152 to rotate. The second screw rod 152 and the second mounting seat 153 rotate relative to each other, and the limiting guide rail 18 and the limiting guide groove 19 limit the movement direction of the second mounting seat 153, so that the second mounting seat 153 drives the first rotating roller 62 to move away from the second rotating roller 63, and the distance between the first rotating roller 62 and the second rotating roller 63 becomes larger, and the workpiece 10 falls from the placement space 25 to the falling space 22.

[0052] When the workpiece 10 passes the crack detection, the workpiece 10 continues to move along the length direction of the inclined track 11 under the action of gravity; when the workpiece 10 fails the crack detection, the unqualified workpiece 10 needs to be discarded. At this time, the first cylinder 23 is used to drive the first shaving plate 72 to slide in the groove 21 until the end of the first shaving plate 72 away from the first cylinder 23 retracts into the groove 21. At this time, the workpiece 10 that falls into the falling space 22 falls out of the inclined track 11 along the mounting plate 71 and enters the first NG material box 24.

[0053] Reference Figure 3 The hardness detection component 8 includes a hardness detection probe 81 and a limit plate 82. The hardness detection probe 81 and the limit plate 82 are both arranged on the workbench 1. The limit plate 82 is used to limit the position of the workpiece 10 on the inclined track 11. The limit plate 82 is arranged on the side of the hardness detection probe 81 close to the inclined track 11 close to the workbench 1. The workbench 1 is provided with a second cylinder 26 for driving the limit plate 82 to slide along a direction perpendicular to the inclined track 11.

[0054] Reference Figure 3The second shaving assembly 9 includes a first conveyor 91 for conveying workpieces 10, a third cylinder 92 arranged on the workbench 1, and a second shaving plate 93 for pushing the workpiece 10 away from the first conveyor 91. The third cylinder 92 is used to push the second shaving plate 93 in a moving direction perpendicular to the first conveyor 91. A penetration groove 27 for the second shaving plate 93 to slide through is provided on the frame of the first conveyor 91. A second NG material box 28 for placing unqualified workpieces 10 is provided on the side of the first conveyor 91 away from the third cylinder 92. The second NG material box 28 is communicated with the penetration groove 27.

[0055] Adjustment plates 29 for limiting the position of the workpiece 10 are arranged on both sides of the first conveyor 91. The two adjustment plates 29 are fixedly connected to the first conveyor 91. Limiting inclined surfaces 30 are arranged on the opposite side walls of the two adjustment plates 29. The two limiting inclined surfaces 30 are mutually enclosed to form an enclosed space 31 for making the axial direction of the workpiece 10 parallel to the conveying direction of the first conveyor 91. The distance between the two limiting inclined surfaces 30 decreases from the hardness detection probe 81 to the direction of the second shaving plate 93. A baffle plate 32 is fixedly connected to the end of the first conveyor 91 away from the hardness detection probe 81. The baffle plate 32 and the two adjustment plates 29 are used to limit the position of the workpiece 10 to facilitate the robot 3 to grasp it.

[0056] When testing the hardness of the workpiece 10, the limit plate 82 moves toward the inclined track 11 under the action of the second cylinder 26 until it blocks the inclined track 11. At this time, the workpiece 10 is restricted by the limit plate 82 on the side of the inclined track 11 away from the first conveyor 91, which is convenient for using the hardness detection probe 81 to detect the hardness of the workpiece 10. When the detection is completed, the second cylinder 26 is used to pull the limit plate 82 in the direction away from the inclined track 11, so that the workpiece 10 moves along the length direction of the inclined track 11 under the action of gravity.

[0057] When the hardness test of the workpiece 10 is qualified, the qualified workpiece 10 falls onto the first conveyor 91 through the inclined track 11, and the first conveyor 91 conveys the workpiece 10 in the direction close to the baffle 32. At this time, the position of the workpiece 10 is adjusted by using two adjustment plates 29, so that when one end of the workpiece 10 abuts against the baffle 32, the axial direction of the workpiece 10 is parallel to the conveying direction of the first conveyor 91, and finally the workpiece 10 is grabbed and arranged by the robot 3; when the hardness test of the workpiece 10 is unqualified, when the unqualified workpiece 10 moves to the front of the second shaving plate 93 driven by the first conveyor 91, the third cylinder 92 is started, and the second shaving plate moves in a conveying direction perpendicular to the first conveyor 91 driven by the third cylinder 92, thereby pushing the unqualified workpiece 10 away from the first conveyor 91, and the workpiece 10 with unqualified hardness enters the second NG material box 28 through the penetration groove 27, realizing the secondary shaving of the workpiece 10.

A storage rack 33 is provided on the workbench 1. The storage rack 33 includes two clamps 34. The opposite side walls of the two clamps 34 enclose a storage space 35 for stacking a plurality of empty trays 401 in a vertical direction.

The first lifting bracket 361 is used to support a plurality of material trays 401. Both ends of the third screw rod 363 are rotatably connected to the workbench 1. The third screw rod 363 is vertically arranged. The third screw rod 363 is threadedly connected to the first lifting bracket 361. The sixth motor 362 is fixedly connected to the workbench 1. The output shaft of the sixth motor 362 is transmission-connected with the first synchronous wheel 37. One end of the third screw rod 363 is transmission-connected with the second synchronous wheel 38.
