DETAILED DESCRIPTION

[0033] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0034] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0035] Chinese patent CN205404493U includes a base, upper and lower cylinders, a piston rod, and a lifting lug. One end of the lifting lug is connected to the upper and lower cylinders via a connector, and the output ends of the upper and lower cylinders are connected to one end of the piston rod. The other end of the piston rod is provided with a connecting seat, which is connected to the base via bolts. A connecting crankshaft is also provided between the connecting seat and the base, and a needle roller bearing is provided at the outer end of the connecting crankshaft. A sensor probe is provided at the top of the connecting crankshaft. A magnet and a magnetic block are provided on the base. In this patent, the sensor probe is driven by the upper and lower cylinders, so that the sensor probe and the object being measured are at the same level. This method is prone to frequent compression of the probe, which can easily damage the sensor probe. Replacing the sensor probe requires disassembling the entire flaw detection device, making parts replacement inconvenient. The magnet and magnetic block are fixed in position on the base, which easily attracts impurities such as iron filings, making them difficult to remove and affecting the detection accuracy of the sensor probe.

[0036] The embodiment of the utility model provides a magnet flipping device, which can automatically control the flipping of the magnet without the need for manual rotation of the magnet, thereby reducing the complexity of the operation and improving the working efficiency of the flaw detection device.

[0037] like Figure 1-Figure 2 As shown, the magnet flipping device 10 provided in the embodiment of the present invention includes a housing 100 , a driving member 200 , a mounting bracket 300 and a magnetic member 400 .

[0038] The housing 100 has a receiving cavity 110 and a mounting hole 120 , and the mounting hole 120 is connected to the receiving cavity 110 .

[0039] The driving member 200 has a transmission shaft 210 . The driving member 200 is located outside the accommodating cavity 110 . The transmission shaft 210 is movably disposed in the mounting hole 120 .

[0040] The mounting bracket 300 is located in the accommodating cavity 110 . The mounting bracket 300 is rotatably connected to the housing 100 . The transmission shaft 210 is connected to the mounting bracket 300 to drive the mounting bracket 300 to rotate.

[0041] The magnetic member 400 is mounted on the mounting bracket 300 so that the magnetic member 400 rotates along with the mounting bracket 300 .

[0042] In this way, the driving member 200 drives the mounting bracket 300 and the magnetic member 400 to rotate so that the suction direction of the magnetic member 400 is perpendicular to the surface of the steel plate, thereby improving the adsorption effect. That is to say, the flipping of the magnetic member 400 is automatically controlled by the driving member 200, and there is no need for manual rotation of the magnetic member 400, thereby reducing the complexity of the operation and improving the working efficiency of the flaw detection device. In addition, the automated operation can reduce the direct contact between the operator and the equipment, thereby helping to reduce the risk of safety accidents caused by operational errors during the operation.

[0043] It can be understood that the rotation axis of the mounting bracket 300 and the rotation axis of the transmission shaft 210 are located in different planes along the vertical direction, so that the transmission shaft 210 can drive the mounting bracket 300 to rotate, and then the magnetic member 400 rotates with the mounting bracket 300.

[0044] In some embodiments, after the magnetic member 400 rotates to a suitable position following the mounting bracket 300 , the magnetic member 400 can generate a magnetic attraction force on the workpiece, so as to facilitate subsequent detection of the workpiece.

[0045] In some embodiments, there are multiple options for the magnetic member 400 . For example, the magnetic member 400 may be a magnet; or, for another example, the magnetic member 400 may be an electromagnet.

[0046] like Figure 3-Figure 5 As shown, in some embodiments, the magnet flipping device 10 includes a first connecting member 500 located in the accommodating cavity 110, and the first connecting member 500 is provided with a connecting hole 510, and the connecting hole 510 penetrates the first connecting member 500 along the radial direction of the first connecting member 500; the mounting bracket 300 includes a connecting rod 310 and a mounting bracket body 320, the connecting rod 310 is rotatably connected to the mounting bracket body 320 and is passed through the connecting hole 510, the mounting bracket body 320 is rotatably connected to the shell 100, the magnetic member 400 is installed on the mounting bracket body 320, and the transmission shaft 210 is connected to the first connecting member 500 to drive the mounting bracket body 320 to rotate.

[0047] The driving member 200 may be a cylinder, and the transmission shaft 210 may be a cylinder piston rod of the cylinder. The connecting hole 510 may be a waist-shaped hole. When the magnet flipping device 10 is in operation, the driving member 200 is located above the mounting bracket 300. When the driving member 200 is connected to an external power source and is in operation, the transmission shaft 210 may move downward, and the connecting rod 310 may move horizontally in the connecting hole 510, so that the transmission shaft 210 can drive the mounting bracket body 320 to deflect through the first connecting member 500 and the connecting rod 310, thereby causing the magnetic member 400 to rotate along with the mounting bracket body 320.

[0048] In other embodiments, the driving member 200 may be an electric push rod, and the transmission shaft 210 may be a push rod of the electric push rod.

[0049] In this embodiment, the connecting rod 310 is rotatably connected to the mounting bracket body 320. The connecting rod 310 can be connected to the mounting bracket body through a bearing, thereby driving the mounting bracket body to deflect, so that the magnetic member 400 rotates with the mounting bracket 300.

[0050] The connecting rod 310 may be provided with a first bearing 311 and a second bearing 312, respectively connected to the ends of the connecting rod 310. The first bearing 311 and the second bearing 312 each have an inner ring and an outer ring. The inner ring of the first bearing 311 is connected to one end of the connecting rod 310, and the outer ring of the first bearing 311 is connected to the mounting bracket body 320. The inner ring of the second bearing 312 is connected to the other end of the connecting rod 310, and the outer ring of the second bearing 312 is connected to the mounting bracket body 320, thereby achieving a rotational connection between the connecting rod 310 and the mounting bracket body 320.

[0051] The first bearing 311 and the second bearing 312 may be needle bearings.

[0052] In this embodiment, the mounting bracket body 320 is rotatably connected to the housing 100 .

[0053] The housing 100 may be provided with a third bearing 313 and a fourth bearing 314, each of which has an inner ring and an outer ring. The inner ring of the third bearing 313 is connected to one end of the mounting bracket body 320, while the outer ring of the third bearing 313 is connected to the housing 100. The inner ring of the fourth bearing 314 is connected to the other end of the mounting bracket body 320, while the outer ring of the fourth bearing 314 is connected to the housing 100. This allows for a rotational connection between the mounting bracket body 320 and the housing 100.

[0054] The third bearing 313 and the fourth bearing 314 may be deep groove ball bearings.

[0055] In some embodiments, the magnet flipping device 10 also includes a second connecting member 600, the second connecting member 600 includes a first connecting portion 610 and a second connecting portion 620, the first connecting portion 610 is connected to the transmission shaft 210, the second connecting portion 620 includes a first side wall 621 and a second side wall 622 arranged at intervals, the first side wall 621 and the second side wall 622 are both connected to the first connecting portion 610, and the first connecting member 500 is clamped between the first side wall 621 and the second side wall 622.

[0056] In this way, the first connecting member 500 is clamped between the first side wall 621 and the second side wall 622 , so that the transmission shaft can be assembled with the first connecting member through the second connecting member.

[0057] In this embodiment, there are multiple ways to connect the first connection part 610 to the transmission shaft 210. For example, the first connection part 610 is connected to the transmission shaft 210 by screw connection; for another example, the first connection part 610 is connected to the transmission shaft 210 by welding connection.

[0058] In this embodiment, the first side wall 621 and the second side wall 622 are both connected to the first connecting portion 610. For example, the first side wall 621 and the second side wall 622 can be connected to the first connecting portion 610 by welding; for another example, the first side wall 621 and the second side wall 622 can be connected to the first connecting portion 610 by screws.

[0059] In addition, the first side wall 621 , the second side wall 622 and the first connecting portion may be integrally formed.

[0060] In some embodiments, the magnet flipping device further includes a first shaft pin 710 and a second shaft pin 720 that are spaced apart. The first shaft pin 710 and the second shaft pin 720 are both radially disposed through the first side wall 621 , the first connecting member 500 and the second side wall 622 along the transmission shaft 210 .

[0061] In this way, the first shaft pin 710 and the second shaft pin 720 are both radially disposed through the first side wall 621 , the first connecting member 500 and the second side wall 622 in the transmission shaft 210 , which helps to limit relative rotation between the first connecting member and the second connecting member.

[0062] In some embodiments, the magnet flipping device also includes a limit member 730, a first anti-loosening gasket 740 and a second anti-loosening gasket 750. The limit member 730 includes a first limit portion 731 and a second limit portion 732 connected to each other. The first limit portion 731 is arranged in the axial direction of the transmission shaft 210 through the first connection portion 610, and the second limit portion 732 is located at one end of the first connection portion 610 facing the first connection member 500. The first anti-loosening gasket 740 and the second anti-loosening gasket 750 are sleeved on the outer periphery of the first limit portion 731 and abut against the first connection portion 610 and the second limit portion 732.

[0063] In this way, the first anti-loosening gasket 740 and the second anti-loosening gasket 750 are sleeved on the outer periphery of the first limiting portion 731 and abut between the first connecting portion 610 and the second limiting portion 732, which can limit the relative rotation of the limiting member 730 and the second connecting member 600.

[0064] In some embodiments, the magnet flipping device also includes a guide member 800, which includes a connected mounting plate 810 and a guide sleeve 820. The guide member 800 is provided with a guide through hole 830, which passes through the mounting plate 810 and the guide sleeve 820. The guide sleeve 820 is passed through the mounting hole 120 and is located in the accommodating cavity 110. The driving member 200 is connected to the shell 100 through the mounting plate 810, the transmission shaft 210 is passed through the guide through hole 830, and the first connecting member 500 and the second connecting member 600 are located in the guide sleeve 820.

[0065] In this way, the driving member 200 is connected to the shell 100 through the mounting plate 810, the transmission shaft 210 is passed through the guide hole 830, and the first connecting member 500 and the second connecting member 600 are located in the guide sleeve 820, so that when the driving member 200 is working, the transmission shaft moves downward, and the first connecting member 500 and the second connecting member 600 located in the guide sleeve 820 can move downward together with the guide sleeve, avoiding unnecessary deviation of the first connecting member 500 and the second connecting member 600 during movement.

[0066] In some embodiments, the guide sleeve 820 is provided with an avoidance gap 821 , and the avoidance gap 821 is connected to the guide through hole 830 and avoids the connecting rod 310 .

[0067] Thus, the guide sleeve 820 is provided with an avoidance notch 821 to avoid interference between the guide sleeve and the connecting rod.

[0068] In some embodiments, the driving member 200 also includes a accommodating chamber 230 and an air pressure through hole 220; the accommodating chamber 230 is located inside the driving member 200, and the transmission shaft 210 can move up and down in the accommodating chamber 230; the air pressure through hole 220 is arranged on the outer wall of the driving member 200 and is connected to the accommodating chamber 230; the air pressure through hole 220 includes a first air pressure through hole 221 and a second air pressure through hole 222; the first air pressure through hole 221 is arranged in the upper half of the driving member 200, and the second air pressure through hole 222 is arranged in the lower half of the driving member 200.

[0069] Among them, the driving member 200 is a cylinder. The first air pressure through hole 221 and the second air pressure through hole 222 can be connected to an air pump. The air pump can be used to deliver compressed air to the accommodating chamber 230 to generate the pressure difference required for the transmission shaft 210 to move along its own axial direction. For example, when the air pump delivers compressed air to the accommodating chamber 230 through the first air pressure through hole 221, a higher air pressure will be formed above the transmission shaft 210, thereby pushing the transmission shaft 210 downward. For another example, when the air pump delivers compressed air to the accommodating chamber 230 through the second air pressure through hole 222, a higher air pressure will be formed below the transmission shaft 210, thereby pushing the transmission shaft 210 upward.

[0070] In some embodiments, the housing 100 is provided with an air duct having an air inlet and an air outlet. The air duct passes through the accommodating cavity 110 , and the air outlet is located at the bottom of the housing 100 .

[0071] The air duct (not numbered in the figure) is not connected to the accommodating chamber 110, and is independently arranged in the accommodating chamber 110. The air inlet 851 can be connected to an air pump or other air source. The air pump can deliver gas to the air duct and discharge gas from the air outlet 852. For the specific air flow path, please refer to Figure 5 The arrows in the flow direction.

[0072] like Figure 5 As shown, gas can enter from the gas inlet 851 and be discharged from the gas outlet 852 along a predetermined path. The gas discharged from the gas outlet 852 can generate an air suspension force on the workpiece, so that the workpiece and the housing 100 are kept at an appropriate distance.

[0073] In other words, the magnetic member 400 can generate a magnetic attraction force on the workpiece, causing the workpiece to approach the housing 100. The air pump can also generate an air suspension force on the workpiece, causing the workpiece to move away from the housing 100. When the magnetic attraction force and the air suspension force are balanced, a small but stable gap can be maintained between the workpiece and the housing 100, thereby helping to reduce the risk of interference between the housing 100 and the workpiece.

[0074] The magnet flipping device 10 further includes a grounding component 900 , which is connected to the housing 100 and is located outside the accommodating cavity 110 .

[0075] In this way, the grounding assembly 900 can shield the interference of the external electromagnetic field by connecting the housing 100 to the ground, thereby reducing the influence of the electromagnetic interference on the flaw detection signal.

[0076] In some embodiments, the magnet flipping device 10 is further provided with a cover plate 920 and an end cap 930 . The cover plate 920 is provided at both ends of the mounting bracket 300 , i.e., the magnet fixing member, and the end cap 930 is installed on both sides of the housing 100 .

[0077] The inner rings of the third bearing 313 and the fourth bearing 314 may be connected to the cover plate 920 , and the outer rings of the third bearing 313 and the fourth bearing 314 may be installed on the end cover 930 .

[0078] Since the magnetic member 400 easily absorbs impurities such as iron filings, and such impurities are not easy to remove, the detection accuracy of the sensor probe is affected.

[0079] Therefore, in some embodiments, a sealing ring 910 may be provided at the connection between the driving member 200 and the guide sleeve 820. This prevents dust from entering the accommodating cavity 110 of the housing 100, and the bottom surface of the housing 100 is less likely to absorb impurities such as iron filings, thereby improving the stability of the magnet flipping device 10.

[0080] In other embodiments, a sealing ring may be provided at the connection between the end cover 930 and the housing 100 , thereby helping to reduce the entry of impurities such as dust into the accommodating cavity 110 of the housing 100 .

[0081] The present application also provides a flaw detection system, including the magnet flipping device, controller and sensor mentioned in the above embodiment; the controller is electrically connected to the driver 200 and the sensor, the sensor is used to detect the position of the workpiece, and the controller controls the driver 200 according to the detection result of the sensor. Among them, the magnet flipping device 10 is installed above the probe in the flaw detection system. When the steel plate passes under the probe, the magnet flipping device 10 can flip the magnetic part, such as a permanent magnet, 90° to generate suction on the steel plate. The sensor can be a laser sensor or an infrared sensor. When the sensor detects that the workpiece is located under the magnet flipping device 10, the sensor can send the detection result to the controller, so that the controller controls the driver to work.

[0082] The flaw detection system may further include a conveying mechanism and a detection mechanism. The conveying mechanism may be a conveyor belt or other mechanism, and the detection mechanism may be an ultrasonic detection mechanism. When the conveying mechanism transports the workpiece to the bottom of the magnet flipping device 10, the controller may control the movement of the driving member 200 based on the detection results of the sensor so that the magnetic member 400 generates a magnetic attraction force on the workpiece, allowing the detection mechanism to detect the workpiece, for example, to detect whether the workpiece has cracks.
