Description

Technical Field

[0001] This utility model relates to the field of magnetic particle testing technology, specifically to an auxiliary device for magnetic particle testing. Background Technology

[0002] Magnetic particle inspection is a method of observing defects using magnetic powder as a display medium. Depending on the type of magnetic powder medium applied during magnetization and the duration of application of magnetic powder to the workpiece, the inspection method is divided into continuous method and residual magnetism method. When a ferromagnetic material workpiece is magnetized, the presence of discontinuities causes local distortion of the magnetic field lines on and near the surface of the workpiece, resulting in a leakage magnetic field. This field attracts the magnetic powder applied to the workpiece surface and forms a visible magnetic mark under appropriate lighting, thus revealing the location, size, shape, and severity of the discontinuity.

[0003] Among flaw detectors, there is a small magnetic particle yoke flaw detector. Due to its portability and built-in battery, it has a great advantage in mobile operations such as outdoor work. However, during flaw detection, the flaw detection data is transmitted to a mobile phone software for recording and display. Flaw detection requires the use of magnetic powder. The operator usually needs to hold the flaw detector with one hand and hold the magnetic powder canister with the other hand to spray the magnetic powder onto the flaw detection surface to complete the flaw detection operation. However, this operation method is not convenient for the operator to observe the condition of the flawed area through the mobile phone software. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for magnetic particle testing, in order to solve the problem that traditional magnetic particle yoke flaw detectors require two hands to operate and are inconvenient to observe the condition of the flawed area through mobile phone software.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetic particle inspection auxiliary device, comprising a U-shaped shell, buttons, and a camera flaw detection assembly. Two buttons are provided, respectively fixedly connected to the top of the outer wall and the top of the inner wall of the U-shaped shell. The camera is fixedly connected to the top of the inner wall of the U-shaped shell and is linearly arranged with one button. An auxiliary assembly is provided inside the U-shaped shell, comprising a suction pump, a threaded groove, an elastic hose, and a nozzle.

[0013] As a further improvement of this utility model, the auxiliary component also includes an L-shaped groove;

[0014] The L-shaped groove is located inside the U-shaped outer shell, and one of its top ends extends to the top of the outer wall of the U-shaped outer shell and fits against the bottom of the outer wall of the suction pump. The outer diameter of the flexible hose is smaller than the inner diameter of the L-shaped groove, allowing the flexible hose to extend and retract inside the L-shaped groove.

[0015] As a further improvement of this utility model: the auxiliary components also include a rotating groove and a turntable;

[0016] The rotating groove is located at the bottom of the inner wall of the L-shaped groove. The rotating groove extends to the bottom of the outer wall of the U-shaped outer shell and the inner wall of the U-shaped outer shell. The turntable is rotatably connected to the inner wall of the rotating groove. The turntable is sleeved on the outer wall of the nozzle and is fixedly connected to the nozzle. The turntable and the rotating groove are interference fit, so the rotation of the turntable needs to be manually operated.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] By setting up auxiliary components, when using the flaw detection kit to inspect the area, the operator only needs to screw the magnetic powder canister into the threaded groove to connect the magnetic powder canister to the input end of the suction pump. After pressing the button on the top of the outer wall of the U-shaped housing, the suction pump is started to deliver the magnetic powder from the flexible hose to the nozzle, and then the magnetic powder is sprayed onto the inspection area. Then, the button on the top of the inner wall of the U-shaped housing is pressed, and the inspection area is photographed by the camera and uploaded to the mobile phone software. The operator only needs one hand to hold the flaw detection kit and spray the magnetic powder, and can use the other hand to view the photo on the mobile phone software to confirm the inspection location.

[0027] 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.

[0028] Please see Figures 1-5In this embodiment of the present invention, a magnetic particle testing auxiliary device includes a flaw detection component 1 consisting of a U-shaped housing 101, a button 104, and a camera 105. Two buttons 104 are provided, which are respectively fixedly connected to the top of the outer wall of the U-shaped housing 101 and the top of the inner wall of the U-shaped housing 101. The camera 105 is fixedly connected to the top of the inner wall of the U-shaped housing 101 and is arranged linearly with one button 104. An auxiliary component 2 is provided inside the U-shaped housing 101. The auxiliary component 2 includes a suction pump 201, a threaded groove 202, an elastic hose 205, and a nozzle 206.

[0029] The suction pump 201 is fixedly connected to the top of the outer wall of the U-shaped housing 101 and electrically connected to another button 104. The threaded groove 202 is provided on the top of the outer wall of the suction pump 201 and is connected to the inlet of the suction pump 201. One end of the elastic hose 205 is fixedly connected to the output end of the suction pump 201. The elastic hose 205 is slidably connected to the inside of the side of the U-shaped housing 101 near the button 104. The nozzle 206 is fixedly connected to the outer wall of the other end of the elastic hose 205 and extends to the inner wall of the U-shaped housing 101.

[0030] In this embodiment: When using the flaw detection component 1 to detect flaws in the area to be detected, the operator only needs to first screw the magnetic powder canister into the threaded groove 202 to connect the magnetic powder canister to the input end of the suction pump 201. Then, after pressing the button 104 on the top of the outer wall of the U-shaped housing 101, the suction pump 201 starts, drawing the magnetic powder out of the magnetic powder canister and then delivering it to the nozzle 206 through the elastic hose 205, thereby spraying the magnetic powder onto the area to be detected. Then, pressing the button 104 on the top of the inner wall of the U-shaped housing 101 activates the camera 105 to take a picture of the area to be detected and upload it to the mobile phone software. The operator only needs one hand to hold the flaw detection component 1 and perform the operation of spraying magnetic powder, so that the operator can use the other hand to view the picture on the mobile phone software to determine the location of the flaw.

[0031] Please refer to this carefully. Figures 1-4 The flaw detection component 1 also includes a battery 102;

[0032] The U-shaped housing 101 houses a control module for transmitting signals and controlling circuits. The button 104 is electrically connected to the control module. The battery 102 is fixedly connected to the outer wall of one side of the U-shaped housing 101 and is electrically connected to the control module to provide power to the flaw detection assembly 1.

[0033] In this embodiment: By setting up battery 102, power is supplied to the control module inside the U-shaped shell 101, thereby controlling the flaw detection component 1 to perform flaw detection operation on the flaw detection area and start the suction pump 201 to spray magnetic powder through two buttons 104 respectively.

[0034] Please refer to this carefully. Figures 1-4The flaw detection component 1 also includes an electromagnetic rod 103;

[0035] Two electromagnetic rods 103 are provided. The two electromagnetic rods 103 are symmetrically arranged and fixedly connected to the bottom of the outer wall of one end of the opening of the U-shaped housing 101. The electromagnetic rods 103 are composed of multiple rotatably connected electromagnets. The electromagnetic rods 103 are electrically connected to the button 104 on the top of the inner wall of the U-shaped housing 101 to control whether the electromagnetic rods 103 generate magnetic force.

[0036] In this embodiment: by setting up an electromagnetic rod 103, the electromagnetic rod 103 can be controlled by a button 104 to generate magnetic force, thereby providing magnetism to the flaw detection area. At the same time, the electromagnetic rod 103 is composed of multiple electromagnets connected in rotation, so that the distance between the bottom ends of two electromagnetic rods 103 can be adjusted, which facilitates flaw detection operations on different flaw detection areas.

[0037] Please refer to this carefully. Figure 2 The flaw detection component 1 also includes an illumination lamp 106;

[0038] The lighting lamp 106 is fixedly connected to the bottom of the inner wall of the U-shaped housing 101, and is linearly distributed with the camera 105 and the button 104 in sequence. The lighting lamp 106 is electrically connected to the button 104 at the top of the inner wall of the U-shaped housing 101, so that it can illuminate the flaw detection and replacement when the electromagnetic rod 103 is energized to generate magnetic force.

[0039] In this embodiment: by setting up a lighting lamp 106, the flaw detection area under the U-shaped outer shell 101 is illuminated, so that the condition of the flaw detection area can be clearly captured by the camera 105, thereby facilitating the staff to inspect the condition of the flaw detection area.

[0040] Please refer to this carefully. Figure 3 , Figure 4 The auxiliary component 2 also includes an L-shaped groove 203;

[0041] The L-shaped groove 203 is disposed inside the U-shaped housing 101, and one end of the top extends to the top of the outer wall of the U-shaped housing 101 and fits against the bottom of the outer wall of the suction pump 201. The outer diameter of the flexible hose 205 is smaller than the inner diameter of the L-shaped groove 203, so that the flexible hose 205 can extend and retract inside the L-shaped groove 203.

[0042] In this embodiment: by setting the L-shaped groove 203, the elastic hose 205 can be housed inside the U-shaped outer shell 101, reducing the influence of external factors on the elastic hose 205, so that the magnetic powder can be smoothly delivered from the suction pump 201 to the inside of the elastic hose 205, and finally sprayed from the inside of the nozzle 206.

[0043] Please refer to this carefully. Figures 1-5 Auxiliary component 2 also includes a rotating slot 204 and a turntable 207;

[0044] The rotating groove 204 is located at the bottom of the inner wall of the L-shaped groove 203. The rotating groove 204 extends to the bottom of the outer wall of the U-shaped outer shell 101 and the inner wall of the U-shaped outer shell 101. The turntable 207 is rotatably connected to the inner wall of the rotating groove 204. The turntable 207 is sleeved on the outer wall of the nozzle 206 and is fixedly connected to the nozzle 206. The turntable 207 and the rotating groove 204 are interference fit, so the rotation of the turntable 207 needs to be manually operated.

[0045] In this embodiment: by setting the rotating groove 204 and the turntable 207, the nozzle orientation of the nozzle 206 can be adjusted within a certain range, so that the magnetic powder can be sprayed onto the flaw detection area, ensuring the normal flaw detection function of the flaw detection component 1.

[0046] Please refer to this carefully. Figure 5 The auxiliary component 2 also includes a sector slot 208;

[0047] The fan-shaped groove 208 is located inside the turntable 207 and extends to the outer wall of the turntable 207. The width of the inner wall of the fan-shaped groove 208 is greater than the width of the outer wall of the elastic hose 205. The nozzle 206 extends into the fan-shaped groove 208 and is fixedly connected to the elastic hose 205.

[0048] In this embodiment: by setting the fan-shaped groove 208, when the nozzle 206 is rotated to adjust the direction of spraying magnetic powder, the elastic hose 205 can slide inside the turntable 207, so that the elastic hose 205 will not obstruct the rotation of the turntable 207, thereby ensuring that the nozzle 206 can normally adjust the direction of spraying magnetic powder.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
