Description

A magnetic particle inspection device for complex components Technical Field

[0001] This utility model relates to the field of flaw detector technology, specifically a magnetic particle flaw detector for complex components. Background Technology

[0002] Flaw detectors are non-destructive testing equipment used to detect internal and surface defects in materials or workpieces. They are widely used in industrial manufacturing, construction engineering, aerospace, rail transportation and other fields to ensure the integrity and safety of materials and structures. However, current flaw detectors mainly have the following problems: (1) The spraying angle of the magnetic suspension liquid is not adjustable, resulting in a small spraying range; (2) They can only detect a single type of workpiece and cannot detect different types of workpieces. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a magnetic particle inspection device for complex components, thereby solving the problems mentioned in the background section.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A magnetic particle inspection device for complex components includes a concave chassis with a positioning platform fixed in the middle. A lifting and rotating mechanism is mounted on the positioning platform, and a positioning mechanism is installed on the lifting and rotating mechanism. The lifting and rotating mechanism controls the lifting and rotating of the positioning mechanism. A first housing and a second housing are respectively located at both ends of the positioning platform. Liquid receiving hoppers connected to the chassis are located on both sides of the positioning platform, with drain ports at the bottom of the hoppers. Clamping mechanisms are rotatably connected to both the first and second housings via rotary bearings, and the clamping mechanisms on both sides are arranged opposite to each other. A first driving mechanism is located inside the first housing to drive the clamping mechanism to rotate. A magnetic suspension tank is located on one side of the chassis, and a pump is mounted on the magnetic suspension tank. The pump is connected to the magnetic suspension tank via a liquid delivery pipe. The liquid tank is connected, and an extension plate is connected to the upper part of the second tank facing the first tank. The upper end of the liquid delivery pipe is installed on the extension plate, and two bearing seats are connected to the bottom surface of the extension plate. A nozzle is rotatably connected to the two bearing seats through a rotary bearing. One end of the nozzle is connected to the liquid delivery pipe through a rotary sealing joint. Two rows of counter-sloping nozzles are connected to the bottom surface of the nozzle. A second drive mechanism for driving the nozzle to rotate is provided on the extension plate. An inverted U-shaped coil assembly is slidably arranged on the outer periphery of the first tank inside the housing. A first cylinder is installed on the outer walls of both sides of the housing. The extension end of the first cylinder is connected to the coil assembly. The extension of the first cylinder can push the coil assembly to the top of the positioning platform and insert the extension plate and nozzle into the coil assembly.

[0006] Preferably, the lifting and rotating mechanism includes a rotating column rotatably connected to the positioning platform via a rotary bearing, a lifting rod splined within the rotating column, and a second cylinder installed in the housing. The telescopic end of the second cylinder is rotatably connected to the bottom of the lifting rod via a rotary joint, and the lifting rod can slide within the rotating column. The lifting and rotating mechanism also includes a first motor installed in the housing, a first transmission shaft connected to the first motor via a coupling, a first gear connected to the first transmission shaft, and a second gear connected to the rotating column, wherein the first gear and the second gear mesh.

[0007] The positioning mechanism includes a bearing plate fixedly connected to the upper end of the lifting rod, a side plate connected to one end of the bearing plate, and multiple positioning blocks connected to the bearing plate. The positioning blocks are distributed in a U-shape, and the side plate has a concave groove.

[0008] Through the above technical solution, by controlling the extension of the second cylinder, the lifting rod can be driven to slide within the rotating column. The first motor is then activated, and through the engagement of the first and second gears, the rotating column is driven to rotate. Since the rotating column is splinedly connected to the lifting rod, it drives the lifting rod to rotate, thereby driving the positioning mechanism to rotate. The positioning block on the positioning mechanism can limit one end of the workpiece, while the slot on the side plate can be used to support the pipe fitting, thus confining one end of the workpiece within the slot.

[0009] Preferably, the coil assembly includes mounting plates disposed on the lower part of both sides of the first housing, a plurality of U-shaped coils fixed on the mounting plates, and lifting lugs connected to the outside of the mounting plates. The coils are located between the housing and the first housing. The telescopic end of the first cylinder is connected to the lifting lugs. The housing is provided with guide rails on both sides of the positioning platform, and pulleys are provided on both sides of the first housing, with the pulleys slidably connected to the guide rails.

[0010] By controlling the extension of the first cylinder, the mounting plate can be pushed, thereby causing the pulley to slide on the guide rail until the coil moves above the positioning platform, and the extension plate and nozzle are located inside the coil.

[0011] Preferably, the clamping mechanism includes a sleeve, a telescopic rod splined inside the sleeve, a third cylinder rotatably connected to one end of the telescopic rod via a rotary joint, and a chuck fixedly connected to the other end of the telescopic rod. The chuck has a V-shaped groove, allowing the telescopic rod to slide inside the sleeve. The sleeves of the two clamping mechanisms are rotatably connected to the first housing and the second housing, respectively, and the third cylinders of the two clamping mechanisms are installed inside the first housing and the second housing, respectively.

[0012] The above technical solution allows for the clamping of plate-shaped workpieces via the V-grooves on the two clamping mechanisms. The extension of the third cylinder enables the telescopic rod to move within the sleeve, thereby adjusting the distance between the two clamps to accommodate workpieces of different lengths.

[0013] Preferably, the first drive mechanism includes a second motor installed in the first housing, a second drive shaft connected to the second motor via a coupling, a third gear connected to the second drive shaft, and a fourth gear connected to a sleeve in the first housing, wherein the third gear meshes with the fourth gear.

[0014] The above technical solution involves starting the second motor, which, through the cooperation of the third and fourth gears, drives the sleeve to rotate. Since the sleeve is splinedly connected to the telescopic rod, the rotation of the sleeve can drive the telescopic rod to rotate together, thereby driving the chuck to rotate and thus driving the workpiece to rotate.

[0015] Preferably, the second drive mechanism includes a protective box mounted on the extension plate, a third motor installed inside the protective box, a third drive shaft connected to the third motor via a coupling, a fifth gear connected to the third drive shaft, and a sixth gear connected to one end of the nozzle, with the fifth gear meshing with the sixth gear.

[0016] Through the above technical solution, the third motor rotates back and forth, and through the cooperation of the fifth and sixth gears, drives the nozzle to deflect in the opposite direction, thereby causing the nozzle to oscillate with the nozzle, so that the magnetic suspension liquid can be sprayed onto the workpiece over a wide area, increasing the spraying range. The protective box can protect the third motor.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) The magnetic suspension is sent to the nozzle by the pump body and the nozzle is driven to deflect back and forth by the second drive mechanism, thereby driving the nozzle to swing with the nozzle so that the magnetic suspension is sprayed on the workpiece over a large area and the spraying range is increased.

[0019] (2) The clamping mechanism can clamp plate-shaped workpieces, and the positioning mechanism can place irregular workpieces, thereby adapting to different workpieces and improving the detection range of different workpieces. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Example 1

[0041] Please refer to Figures 1-7. A magnetic particle inspection device for complex components includes a concave housing 1. A positioning platform 2 is fixed in the middle of the housing 1. A lifting and rotating mechanism 3 is provided on the positioning platform 2. A positioning mechanism 4 is installed on the lifting and rotating mechanism 3. The lifting and rotating mechanism 3 can control the lifting and rotating of the positioning mechanism 4. The lifting and rotating mechanism 3 includes a rotating column 301 rotatably connected to the positioning platform 2 via a rotary bearing, a lifting rod 302 splinedly connected to the rotating column, and a second cylinder 303 installed in the housing. The telescopic end of the second cylinder 303 is rotatably connected to the bottom of the lifting rod 302 via a rotary joint. The lifting rod 302 can slide within the rotating column 301. The lifting and rotating mechanism 3 also includes a first motor 304 installed in the housing, a first transmission shaft connected to the first motor via a coupling, a first gear 305 connected to the first transmission shaft, and a second gear 306 connected to the rotating column. The first gear 305 and the second gear 306 mesh. The positioning mechanism 4 includes a bearing plate 401 fixedly connected to the upper end of the lifting rod, a side plate 402 connected to one end of the bearing plate, and a plurality of positioning blocks 403 connected to the bearing plate. The positioning blocks 403 are distributed in a U-shape, and the side plate 402 has a concave groove.

[0042] As shown in Figures 5, 6, and 7, when fixing the irregular workpiece 22, one end of the irregular workpiece 22 is placed on the support plate 401, and the positioning block 403 restricts one end of the irregular workpiece to a certain area. At the same time, the other end of the irregular workpiece is placed in the groove of the side plate 402, thereby restricting the irregular workpiece and preventing it from falling when the support plate 401 rotates.

[0043] The positioning platform 2 has a first housing 5 and a second housing 6 at its two ends, respectively. Liquid receiving hoppers 7 connected to the chassis are located on both sides of the positioning platform 2. These hoppers receive the magnetic suspension liquid, and a drain port is located at the bottom of each hopper to discharge the magnetic suspension liquid. Clamping mechanisms 8 are rotatably connected to both the first housing 5 and the second housing 6 via rotary bearings. The clamping mechanisms 8 on both sides are arranged opposite to each other. A first drive mechanism 19 is located inside the first housing 5 to drive the clamping mechanisms thereon to rotate. Specifically, the clamping mechanism 8 includes a sleeve 801, a telescopic rod 802 splinedly connected to the sleeve, a third cylinder 803 rotatably connected to one end of the telescopic rod via a rotary joint, and a chuck 804 fixedly connected to the other end of the telescopic rod. The chuck 804 has opposing V-grooves 805, allowing the telescopic rod 802 to slide within the sleeve 801. The sleeves 801 of the two clamping mechanisms are rotatably connected to the first housing and the second housing, respectively, and the third cylinders 803 of the two clamping mechanisms are installed inside the first housing and the second housing, respectively. The V-groove 805 of the chuck 804 can clamp the end of the plate 21. When clamping the plate 21, the two ends of the plate 21 are aligned with the V-groove 805, and then the third cylinders 803 on both sides are controlled to extend, driving their respective telescopic rods 802 to move within the sleeve 801 until the chucks on both sides clamp the plate, thereby completing the fixing of the plate. The first drive mechanism 19 includes a second motor 191 installed in the first housing, a second drive shaft connected to the second motor via a coupling, a third gear 192 connected to the second drive shaft, and a fourth gear 193 connected to the sleeve in the first housing. The third gear 192 and the fourth gear 193 mesh. The second motor 191 is controlled to work. Through the cooperation of the third gear 192 and the fourth gear 193, the sleeve 801 is driven to rotate. Since the sleeve 801 is splinedly connected to the telescopic rod 802, the rotation of the sleeve 801 can drive the telescopic rod 802 to rotate together, thereby driving the chuck 804 to rotate, so as to drive the plate to rotate.

[0044] An inverted U-shaped coil assembly 17 is slidably disposed within the casing 1, located on the periphery of the first housing 5. First cylinders 18 are mounted on the outer walls of both sides of the casing 1. The coil assembly 17 includes mounting plates 171 located at the lower part of both sides of the first housing, several U-shaped coils 172 fixed to the mounting plates, and lifting lugs 173 connected to the outer side of the mounting plates. The coils 172 are located between the casing 1 and the first housing 5. The extension end of the first cylinder 18 is connected to the lifting lugs 173. Guide rails 174 are provided on both sides of the casing 1 on the positioning platform, and pulleys 175 are provided on both sides of the first housing 5, slidably connected to the guide rails 174. The extension of the first cylinder 18 pushes the coil assembly 17 to the top of the positioning platform 2, surrounding the workpiece and generating a circumferential magnetic field on it.

[0045] A magnetic suspension tank 9 is provided on one side of the casing 1. A pump body 10 is installed on the magnetic suspension tank 9. The pump body 10 is connected to the magnetic suspension tank 9 through a liquid delivery pipe 11. An extension plate 12 is connected to the upper part of the side of the second casing 6 facing the first casing. The upper end of the liquid delivery pipe 11 is installed on the extension plate 12. Two bearing seats 13 are connected to the bottom surface of the extension plate 12. A nozzle 14 is rotatably connected to the two bearing seats 13 through a rotary bearing. One end of the nozzle 14 is connected to the liquid delivery pipe 11 through a rotary sealing joint 15. Two rows of counter-sloping nozzles 16 are connected to the bottom surface of the nozzle 14. When the first cylinder 18 extends and pushes the coil 172 to move, the coil 172 will simultaneously reach the periphery of the extension plate 12 and the nozzle 14, that is, the extension plate 12 and the nozzle 14 can be inserted into the coil. The extension plate 12 is equipped with a second drive mechanism 20 for driving the nozzle 14 to rotate. The second drive mechanism 20 includes a protective box 201 mounted on the extension plate, a third motor 202 installed inside the protective box 201, and a third transmission shaft connected to the third motor 202 via a coupling. A fifth gear 203 is connected to the third transmission shaft, and a sixth gear 204 is connected to one end of the nozzle 14. The fifth gear 203 and the sixth gear 204 mesh. By controlling the reciprocating rotation of the third motor 202, the nozzle 14 is driven to deflect in the opposite direction through the cooperation of the fifth gear 203 and the sixth gear 204, thereby causing the nozzle 16 to sway with the nozzle 14, so that the magnetic suspension liquid is sprayed onto the workpiece over a large area and evenly.

[0046] The working principle of this embodiment is as follows:

[0047] When inspecting the irregularly shaped workpiece 22, one end of the workpiece 22 is placed on the support plate 401, and the other end is placed in the slot of the side plate 402, thereby restricting the irregularly shaped workpiece. Then, the first cylinder 18 is extended, driving the coil assembly 17 to move until the coil 172 covers the irregularly shaped workpiece, while the nozzle 14 and the nozzle 16 are located inside the coil 172. Then, the magnetic suspension liquid is sent to the nozzle 14 through the pump body 10 and sprayed out by the nozzle 16. During spraying, the nozzle 14 is controlled to swing back and forth by the second drive mechanism 20 to improve the uniformity and range of spraying. Then, the coil 172 is energized to generate a circumferential magnetic field, and the workpiece is then irradiated by a handheld LED ultraviolet lamp (not shown in the attached figure) to complete the inspection of the irregularly shaped workpiece.

[0048] When inspecting the board, align both ends of the board 21 with the V-groove 805, then extend the third cylinders 803 on both sides, driving their respective telescopic rods 802 to move within the sleeve 801 until the clamps 804 on both sides clamp the board, thus fixing the board. Then, place the coil assembly 17 over the board and begin inspection. During inspection, the clamping mechanism 8 is driven to rotate, which in turn rotates the board, improving the inspection range and efficiency.
