Description

Technical Field

[0001] The utility model relates to a parallel magnetization detection component, which is used for detecting defects of ferromagnetic parts.

[0002] The utility model belongs to the field of non-destructive testing equipment. Background Art

[0003] Among conventional nondestructive testing methods, magnetization testing offers advantages such as intuitive defect visualization, high sensitivity, and a low missed detection rate. Magnetization testing is commonly used for ferromagnetic parts on in-service aircraft, such as removable bolts, shafts, and pins.

[0004] The bolts, shafts, and pins used in aircraft are usually short structures, and the direction of fatigue cracks may be axial or circumferential. Therefore, longitudinal magnetization and circumferential magnetization are required to ensure that defects in all directions of the parts are effectively detected.

[0005] Conventional circumferential magnetization testing typically uses a direct current method: the part is clamped between two chucks, a magnetic suspension is applied, and the magnetizing current is simultaneously applied. To achieve 100% circumferential inspection of bolts, shafts, and pins, the testing process must be repeated multiple times: manually rotating the part, re-clamping, and repeating the magnetization test. Magnetization testing is typically performed at 0°, 90°, 180°, and 360° to ensure part quality.

[0006] Furthermore, conventional circumferential magnetization testing requires individual inspection of each component, making it difficult to implement mass-produced, automated testing. Consequently, conventional magnetization testing is cumbersome, time-consuming, and inefficient, increasing aircraft operating and maintenance costs.

[0007] At the same time, direct clamping of such short structural parts can easily cause arc burns, thus posing risks to personnel protection and parts quality.

[0008] Parallel magnetization methods are now being introduced. Common parallel magnetization methods include cable parallel magnetization and plate parallel magnetization. Specifically, the part is placed near a current-carrying conductor and the magnetic field generated by the conductor is used to induce magnetization on the part. This method is often used for thin and short ferromagnetic parts to avoid burns and achieve the desired magnetic particle inspection results. However, conventional parallel magnetization methods can only magnetize a part locally and still cannot achieve efficient inspection. Utility Model Content

[0048] First, the present invention relates primarily to nondestructive testing devices for ferromagnetic parts in any manufacturing field. In particular, the present invention relates to the fields of aircraft production, operation, and maintenance, and, for example, to the nondestructive testing of ferromagnetic parts of aircraft, but is not limited to nondestructive testing of parts in this field.

[0049] As used herein, the term “fixed” is intended to describe a mechanism where one component is connected to another component and can maintain a fixed position relative to each other so that forces, torque, etc. can be transferred from one component to the other.

[0050] "Shape adaptation" in the context of the present invention is intended to describe that the shape of at least a portion of one component and the shape of at least a portion of another component can match each other. The "shape adaptation" does not require complete shape matching, and can be partial shape matching. For example, one component is convex and can be received in a curved recess of another component, or the key of one component can be partially received in the groove of another component. As long as there is a force transmission path, no matter how many, it is within the scope of the present invention.

For example, an axially extending feature of a component may be a feature extending generally along a direction parallel to the axis of symmetry or the elongated direction of the component. Similarly, as used herein, the term "radial" and variations thereof refer to a direction generally perpendicular to the corresponding axial direction. For example, a radially extending structure of a component may extend generally, at least partially, along a direction perpendicular to the longitudinal or central axis of the component. As used herein, the term "circumferential" and variations thereof refer to a direction extending around the circumference of an object, or around an axis of symmetry, an axis of rotation, a central axis, or the elongated direction of a particular component or system. As used herein, the terms "comprises," "having," "includes," and variations thereof are intended to be open-ended transitional phrases, terms, or words requiring the presence of specified components / steps, and also allowing the presence of other components / steps.

[0053] In the present invention, unless explicitly stated otherwise, the terms "first", "second", etc. are not intended to indicate any difference in order, position, quantity or importance, but are merely used as labels to distinguish different positions and components, to distinguish one element, component, region and / or position from another element, component, region and / or position.

[0054] Finally, the numerical values ​​given in each embodiment are only for illustration and are not intended to limit the scope of the present invention.

[0055] In a non-limiting example, the parallel magnetization detection assembly 1 of the present invention includes a long rod conductor 100. The long rod conductor 100 is defined as an electromagnetic conductor extending in a first direction. The long rod conductor 100 can be cylindrical, but the shape is not limited thereto. It can be any long strip shape capable of conducting an electromagnetic field, such as a long rod with a rectangular cross-section.

[0056] In a non-limiting example, the parallel magnetization detection assembly 1 of the present invention includes a tooling box assembly 200 for applying a magnetic suspension and accommodating a part to be tested therein, and for finding surface and near-surface defects of ferromagnetic parts by observing magnetic traces.

[0057] In this example, the tool box assembly 200 may include a box-shaped body, hereinafter referred to as the box body 210, for applying the magnetic suspension therein. The bottom of the box body 210 may have a hollow structure or opening to facilitate the flow of the magnetic suspension out of the box body 210 and reduce weight.

[0058] The box body 210 primarily comprises sidewalls 211 and a bottom wall 212. Preferably, the box body 210 is in the shape of a rectangular parallelepiped, meaning it may have a generally rectangular outer contour or may have rounded corners and edges. In this case, the sidewalls 211 comprise four generally rectangular sidewall sections, such as sidewall sections 211a, 221b, 211c, and 221d. It is understood that the shape of the box body 210 is not limited to this; it may also be cylindrical, in which case the sidewalls 211 form a circumferential cylindrical sidewall.

[0059] In this example, the tooling box assembly 200 may include a clamping assembly 220, which includes at least one group of two clamping assemblies 220, which are correspondingly arranged on two box side wall parts 211a and 211c opposite to each other in the first direction, and are used to clamp the part to be tested between the group of two clamping assemblies 220.

[0060] Preferably, the clamping assembly 220 may include a telescopic clamping portion 221 and a rotation drive portion 222. The telescopic clamping portion 221 is used to adjustably clamp parts of different lengths in a first direction, and the rotation drive portion 222 is used to actuate the telescopic clamping portion 221 and thereby actuate the part to be tested to rotate about the first direction.

[0061] The rotating drive unit 222 passes through the two aforementioned box side wall parts 211a and 211c, for example, through the preset through holes on the two box side wall parts 211a and 211c, and the rotating drive unit 222 and these through holes are sealed by seals to prevent component wear or part of the magnetic suspension from remaining on the inner wall of the hole.

[0062] Preferably, the rotary drive portion 222 includes a rotary motor or a gear mechanism or a slide mechanism to actuate the clamping and telescopic portion 221 to rotate, thereby achieving comprehensive detection of the part to be tested in the circumferential direction without the need for repetitive labor of manual release and re-clamping.

[0063] The clamping and telescopic parts 221 are fixed to the corresponding rotation driving parts 222 and extend toward each other in a first direction within the box body 210 , and are used to clamp the part to be tested with an adjustable length in the first direction.

[0064] Preferably, the telescopic clamping portion 221 may include an inner sleeve 221a and an outer sleeve 221b that are arranged on each other, and the telescopic clamping portion 221 also includes a motor, an electric push rod or a cylinder, such as an actuator structure, to actuate the inner sleeve 221a to move in a first direction relative to the outer sleeve 221b, thereby clamping and releasing the part to be tested.

[0065] Additionally or alternatively, the telescopic clamping portion 221 may include an inner sleeve 221a and an outer sleeve 221b threadedly connected to each other, and the telescopic clamping portion 221 further includes a motor to actuate the inner sleeve 221a to rotate relative to the outer sleeve 221b to actuate the inner sleeve 221a to move in a first direction relative to the outer sleeve 221b, thereby clamping and releasing the part to be tested.

[0066] In this example, the tooling box assembly 200 may include a control box 230, which may be located on the outer periphery of the box sidewall 211. The control box 230 may include, but is not limited to, a power switch button, a clamping and retracting unit switch button, and a rotary drive unit speed adjustment knob to implement the adjustment and detection functions of the parallel magnetization detection assembly according to the present invention.

[0067] In a non-limiting example, the parallel magnetization detection assembly 1 of the present invention includes a locking assembly 300 for locking the tool box assembly 200 to the long rod conductor 100 , specifically, locking the tool box assembly 200 on the surface of the long rod conductor 100 .

[0068] The locking assembly 300 may include a strip-type locking member, but its form is not limited thereto. Instead, it may include any form that can detachably or non-detachably lock the tool box assembly 200 to the long rod conductor 100, such as a snap-fit ​​connector for detachable or a fastening connector for non-detachable.

[0069] The present invention will be further described below in conjunction with specific embodiments and drawings. More details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in a variety of other ways different from the description. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific embodiment.

[0070] Figure 1 The figure schematically shows a top perspective view of a parallel magnetization detection assembly 1 according to an embodiment of the present invention.

[0071] In this example, the tooling box assembly 200 may include six clamping assemblies 220, specifically, three groups of two clamping assemblies 220, which are correspondingly arranged on two box side wall parts 211a and 211c opposite to each other in the first direction, and are used to clamp the parts to be tested between each group of two clamping assemblies 220, thereby realizing batch detection of parts and improving detection efficiency.

[0072] In this example, the control box 230 may include three buttons, a power switch button 230a, a clamping and retracting part switch button 230b, and a rotation drive part speed adjustment knob 230c, to implement the adjustment and detection functions of the parallel magnetization detection assembly according to the present invention.

[0073] When using the parallel magnetization detection assembly 1 of the present invention to detect the part to be tested, first press the power switch button 230a to start the device. Then press the clamping telescopic part switch button 230b, and the clamping telescopic parts 221 of each group of two clamping assemblies 220 will automatically adjust to the appropriate length to clamp the part to be tested. Then, you can apply magnetic suspension, turn on the power, and use a standard notched test piece or a Gauss meter to measure to confirm that the applied magnetic field strength is sufficient to produce a satisfactory magnetic mark display. At this time, turn the rotation drive unit speed adjustment knob 230c to the appropriate rotation speed gear, apply magnetic suspension while turning on the power until the parallel magnetization test is completed.

[0074] Figure 2 The figure schematically shows a bottom perspective view of a parallel magnetization detection assembly 1 according to an embodiment of the present invention.

[0075] In this example, the box body 210 has a box shape and includes a box side wall 211 and a box bottom wall 212. The box bottom wall 212 of the box body 210 faces the long rod conductor 100 and is located at the middle section of the long rod conductor 100 through two locking assemblies 300. The box bottom wall 212 includes a recessed portion on the side facing the long rod conductor 100 that matches the shape of the outer peripheral surface of the middle section.

[0076] In this example, the locking assemblies 300 are all fixed to the side of the box body bottom wall 212 of the box body 210 facing the long rod conductor 100. The locking assemblies 300 can be made of metal or resin and can have a semicircular ring body. The number of locking assemblies 300 is not limited to two.

[0077] Figure 3 and Figure 4 The figure schematically shows a front view of the locking assembly 300 of the parallel magnetization detection assembly 1 according to an embodiment of the present invention in a released position and a locked position.

[0078] The locking assembly 300 includes a slide groove 301, a slide bar 302, a spring 303, and a housing 304. The slide groove 301 and the slide bar 302 are adapted to each other in shape and are engaged by snapping. Figure 3 、 Figure 4 In the embodiment, the slide bar 302 is in the form of an elongated cylinder. The right end of the slide bar 302 is fixed to the right end of the housing 304, and the left end of the slide bar 302 and most of it are stuck in the slide groove 301 at the left end of the housing 304. By bringing the right end and the left end of the housing 304 closer to each other, the spring 303 can be compressed, so that the slide bar 302 is inserted into the slide groove 301 along the extension direction of the slide bar, that is, from Figure 3 Slide the release position to Figure 4 The locking assembly 300 is locked and tightened around the long rod conductor 100 to fix the parallel magnetization detection assembly 1. When the lock needs to be released, the spring 303 is pressed again, the slide 302 is unlocked from the slide groove 301 and the spring 303 is extended, returning along the extension direction of the slide. Figure 3 By moving the tool box assembly 200 of the parallel magnetization detection assembly 1 to the release position, the tool box assembly 200 can be removed from the long rod conductor 100, thereby achieving detachable locking of the tool box assembly 200.

[0079] The structure of the locking assembly 300 is not limited thereto, and may also be other forms, such as any detachable locking structure, such as locking by a latch, a restraining strap, or a fixed connection structure, such as locking by a fastener.
