Description

Technical Field

[0001] The invention relates to the technical field of magnetic suspension, and in particular to a spray-irradiation integrated device for magnetic powder detection. Background Art

[0002] The non-destructive testing method of magnetic particle testing of workpieces using fluorescent magnetic particles is used to detect surface and near-surface crack defects of steel parts. It has long been considered one of the most sensitive methods for surface crack detection. At present, when conducting fluorescent wet magnetic particle testing, two inspectors (main inspector + auxiliary inspector) are usually required to work together. The main inspector controls the cross-type magnetic yoke probe with his right hand to generate a continuous magnetizing field, and holds the magnetic suspension spray can in his left hand to apply the magnetic suspension to the surface to be tested of the workpiece. The auxiliary inspector holds a black light to illuminate the area where the magnetic suspension is applied, so that the main inspector can observe and evaluate the defective magnetic traces. At the same time, the magnetic suspension is prone to precipitation, and it needs to be shaken before each spraying to mix it evenly. When operating the cross-type magnetic yoke probe to detect a welding area, the two probe feet of the probe are generally placed on both sides of the weld for detection, and then the cross-type magnetic yoke probe is rotated about 90° to make the straight line formed by the connection of the two probe feet vertical. Two or more detections can ensure that the area is fully inspected.

[0003] The above information disclosed in this Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not constitute the prior art that is already known to one of ordinary skill in the art. Summary of the invention

[0004] The purpose of the present invention is to design a device that only needs one person to operate and does not require two inspectors to cooperate in the work. The device can complete the inspection work alone, and does not require manual shaking of the spray can every time. The device can automatically rotate the yoke probe 90° to solve the above-mentioned deficiencies in the technology.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a magnetic powder detection integrated spraying and irradiation device, comprising a shell, two probes installed in the shell, and a spray can with a nozzle facing between the two probes, the spray can contains a magnetic suspension, the shell contains a power supply component for powering the probes, the bottom of the shell passes through and is rotatably connected to a first column, the bottom end of the first column is fixedly connected to a box body, the two probes both pass through the first column and the box body and are fixedly connected to the two, a black light lamp irradiating between the two probes is installed in the box body, a power component for driving the first column to rotate 90° is installed in the shell, a bevel gear ring is fixedly installed at the bottom of the shell, a bevel gear is meshed with a bevel gear on one side of the bevel gear ring, a first shaft is fixedly installed at the bottom of the bevel gear, a reciprocating motion component is installed at the bottom of the first shaft, a positioning component for disassembling and assembling the spray can is installed at the output end of the reciprocating motion component, an electric telescopic rod is installed in the positioning component, and a pressing piece for pressing the spray can to spray is fixedly installed at the output end of the electric telescopic rod;

[0006] Turn on the black light to illuminate the workpiece between the two probe pins. After the first inspection of the shell with the probe pin, the power component drives the two probe pins and the bevel gear to rotate 90° around the bevel gear ring. After driving the reciprocating motion component to repeatedly shake the spray can, the spray can sprays the magnetic suspension between the two probe pins and then uses the probe pin for inspection.

[0007] Preferably, the power assembly includes a motor, a worm fixedly mounted at the output end of the motor, and a worm wheel meshing at one side of the worm, and the worm wheel is fixed on the outer peripheral surface of the first column.

[0008] Preferably, the reciprocating motion assembly includes a cam fixedly mounted at the bottom end of the first shaft, a hollow block rollingly connected to the outside of the cam, and a sliding rod fixedly connected at both ends of the hollow block, wherein the sliding rod passes through the box body and is slidably connected to the box body.

[0009] Preferably, the positioning assembly includes a first tube in contact with the tail of the spray can, a threaded rod spirally rotating in the first tube, a push plate fixedly connected to one end of the threaded rod, a knob fixedly connected to the other end of the threaded rod, a second tube in contact with the head of the spray can, and a block fixedly connected to the inner wall of the second tube, the block is in contact with the end of the spray can, the pressing piece is in contact with the end of the spray can, the electric telescopic rod is installed inside the second tube, and the first tube and the second tube are fixedly connected to the ends of two sliding rods respectively.

The first switch controls the power supply component to supply power to the probe foot, the second switch controls the opening and closing of the motor, and the motor output shaft automatically stops rotating after rotating a predetermined number of times. When the second switch is turned on again, the motor output shaft reverses a predetermined number of times. The third switch controls the black light to be normally open or normally closed, and the fourth switch controls the opening and closing of the motor.

[0013] Preferably, the first switch is arranged at the front end above the handle, the second switch and the fourth switch are arranged below the handle, and the third switch is arranged at the rear end above the handle.

[0014] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0016] After pressing the fourth switch, the device will control the motor to rotate forward or reverse 90°, thereby driving the probe to automatically rotate 90° around the central axis of the first column. The user only needs to lift the handle and then put it down, unlike the prior art where the wrist is turned to manually rotate the probe, which has the problem of a large difference between the rotation angle and 90°.

[0017] When the probe foot in the device rotates, it also drives the spray can to shake through the reciprocating motion component, which solves the problem of manually shaking the spray can every time it is used in the prior art. The spray can can be shaken automatically to avoid precipitation of the magnetic suspension.

[0018] At the same time, the device can adjust the knob to enable the push plate and the stopper to clamp spray cans of different lengths to be suitable for magnetic suspensions of different brands. BRIEF DESCRIPTION OF THE DRAWINGS

The positioning assembly 12 includes a first barrel 12a in contact with the tail of the spray can 3, a threaded rod 12b spirally rotating in the first barrel 12a, a push plate 12c fixedly connected to one end of the threaded rod 12b, a knob 12d fixedly connected to the other end of the threaded rod 12b, a second barrel 12e in contact with the head of the spray can 3, and a stopper 12f fixedly connected to the inner wall of the second barrel 12e, wherein the stopper 12f is in contact with the end of the spray can 3, the pressing member 14 is in contact with the end of the spray can 3, the electric telescopic rod 13 is installed inside the second barrel 12e, the first barrel 12a and the second barrel 12e are fixedly connected to the ends of the two sliding rods 11c respectively, a through hole 15 is opened on the side wall of the second barrel 12e, and the nozzle of the spray can 3 faces the through hole 15. Through hole 15, a handle 16 is fixedly connected to the top of the shell 1, and a first switch 17, a second switch 18, a third switch 19 and a fourth switch 20 are fixedly installed on the handle 16. The first switch 17 controls the power supply component to supply power to the probe foot 2, and the second switch 18 controls the opening and closing of the motor 7a. The output shaft of the motor 7a automatically stops rotating after rotating a predetermined number of times. When the second switch 18 is turned on again, the output shaft of the motor 7a reverses the predetermined number of times. The third switch 19 controls the black light lamp 6 to be normally open and normally closed, and the fourth switch 20 controls the opening and closing of the motor 7a. The first switch 17 is arranged at the front end above the handle 16, the second switch 18 and the fourth switch 20 are arranged below the handle 16, and the third switch 19 is arranged at the rear end above the handle 16.

[0031] Step 1: The user moves the spray can 3 between the first tube 12a and the second tube 12e, and then rotates the knob 12d. The knob 12d drives the threaded rod 12b, and the threaded rod 12b moves axially through the threaded connection. The threaded rod 12b pushes the push plate 12c, and the push plate 12c pushes the head of the spray can 3 into the second tube 12e until the pressing member 14 and the stopper 12f are both in contact with the head of the spray head. At this time, the push plate 12c and the stopper 12f jointly clamp the spray can 3, and the spray head on the spray can 3 needs to face the through hole 15;

[0032] Step 2: The user holds the handle 16 with his right hand, pushes the third switch 19 to start the black light 6 to emit light, then moves the device, and makes the two probes 2 contact the workpiece. If the weld is to be detected, they are located on both sides of the weld. Then, the user pinches the second switch 18 with his index finger. At this time, the output shaft of the electric telescopic rod 13 will extend, thereby driving the pressing member 14 to push the nozzle on the spray can 3, and the suspension magnetic liquid will be sprayed onto the workpiece surface between the two probes 2. When the second switch 18 is released, the electric telescopic rod 13 will be controlled to automatically reset, so that the suspension magnetic liquid will no longer be sprayed.

[0033] Step 3: The user then presses the first switch 17 with his thumb, and releases the first switch 17 after supplying power for a certain period of time in the prior art. When the probe foot 2 is powered on, a continuous magnetization field is generated. At this time, the user observes the magnetic traces on the surface of the workpiece in combination with the light irradiated by the black light lamp 6;

[0034] Step 4: The user then lifts the handle 16 a little so that the probe foot 2 no longer contacts the workpiece surface, and then presses the fourth switch 20 and releases it. The fourth switch 20 will control the motor 7a to rotate forward for a predetermined number of turns, and the output shaft of the motor 7a will drive the worm 7b to rotate, and the worm 7b will drive the worm gear 7c to rotate, and the worm gear 7c will drive the first column 4 to rotate, and the first column 4 will drive the box body 5 to rotate, and the box body 5 and the first column 4 will drive the two probe feet 2 to rotate, and the box body 5 will also drive the first shaft 10, and the first shaft 10 will drive the bevel gear 9, and the bevel gear 9 will rotate while orbiting because of the meshing with the bevel gear ring 8, and the bevel gear 9 will rotate with the first shaft 10. The first shaft 10 will drive the cam 11a to rotate, the cam 11a will drive the hollow block 11b to swing back and forth, the hollow block 11b will drive the slide bar 11c, the slide bar 11c will drive the first tube 12a and the second tube 12e to swing back and forth, the first tube 12a and the second tube 12e will drive the spray can 3 to swing back and forth, so as to shake the precipitated suspended magnetic liquid in the spray can 3 evenly. After the motor 7a rotates forward for a predetermined number of times, the two probes 2 will rotate 90° around the central axis of the first column 4, and the motor 7a will automatically stop rotating. When the fourth switch 20 is pressed next time, the motor 7a will reverse for a predetermined number of times, and the direction of the motor 7a maintains the rule of forward rotation-reverse rotation-forward rotation-reverse rotation;

[0035] Step 5: Then the user can detect and observe the magnetic traces again according to the above steps 2 and 3.

[0036] It is important to note that the construction and arrangement of the present application shown in a number of different exemplary embodiments are exemplary only. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and proportion of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, colors, changes in orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application.
