Description

Technical Field

[0001] This utility model relates to the field of wire breakage failure analysis technology, and in particular to a clamping device. Background Technology

[0002] Electrical conductors are fundamental components of aircraft power transmission and distribution systems, used in large quantities, in various types, with wide applications, and operating in complex environments. Due to the structural characteristics of aircraft, not only are the volume and weight of conductors limited, but the installation space is also extremely confined. Most conductors are bundled and laid between various airborne electrical devices or within the aircraft's walls, operating under conditions of vibration and friction for extended periods. This makes them highly susceptible to failure, leading to power outages and other consequences that seriously endanger flight safety. When a conductor fails, it is necessary to analyze the fracture surface to determine the failure mechanism and cause, and to propose corresponding preventative measures to prevent recurrence.

[0003] Currently, wire fracture surfaces are primarily observed macroscopically using a stereomicroscope to determine the presence of cracks, corrosion products, etc. During observation, the wire must be held by hand or fixed to a test block, ensuring the end face is perpendicular to the objective lens. Due to the small size of the wire, hand-held observation can cause difficulty in focusing the fracture surface due to hand-held shaking, resulting in a blurred field of view and increased observation time. Furthermore, when observing the fracture surfaces of multi-core wires, uneven stress on the wire can cause some areas of the fracture to be beveled, requiring continuous adjustment of the angle to ensure the observed area is perpendicular to the objective lens. When using a test block for fixation, the test block lacks rotation capabilities, resulting in some areas not having a good field of view. Utility Model Content

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the first feature can include the feature and the first feature being in direct contact, or it can include the feature and the first feature not being in direct contact but being in contact through another feature between them. Furthermore, "above," "over," and "on top" of the first feature includes the feature being directly above or diagonally above the first feature, or simply indicates that the feature is at a higher horizontal level than the first feature. "Below," "below," and "under" the first feature includes the feature being directly below or diagonally below the first feature, or simply indicates that the feature is at a lower horizontal level than the first feature.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1-6 As shown, this utility model provides a clamping device for clamping wires, including a clamping assembly 1 and an angle adjustment assembly 2. The clamping assembly 1 includes a platform 11 and a locking member 12. The platform 11 is provided with a receiving groove 110. The locking member 12 is adjustablely connected to the platform 11, and the wire can be clamped between the locking member 12 and the inner wall of the receiving groove 110. The angle adjustment assembly 2 includes a base 21, a rotating member 22 and a fixing member 23. The rotating member 22 is connected to the platform 11 and rotatably connected to the base 21. The fixing member 23 is adjustablely connected to the base 21 and can lock the rotating member 22 to the base 21.

[0034] When it is necessary to inspect the wire break, the wire is placed between the inner wall of the receiving groove 110 and the locking member 12, while the wire break extends out of the receiving groove 110. By adjusting the locking member 12, the wire can be clamped between the locking member 12 and the inner wall of the receiving groove 110. Thus, when observing with a microscope, the position of the wire break is fixed, and the objective lens can accurately focus on the break, avoiding problems such as difficulty in focusing and blurred field of view due to shaking, reducing observation time and improving observation efficiency. Furthermore, when it is necessary to observe the beveled part of the multi-core wire break, the operator can rotate the rotating member 22 according to the actual situation, so that the rotating member 22 drives the wire on the stage 11 to adjust the angle. After the wire break is adjusted to a suitable angle, the operator locks the rotating member 22 to the base 21 by adjusting the fixing member 23, thereby fixing the wire angle and making it easier for the objective lens to focus on the wire break.

[0035] Specifically, the locking element 12 is screwed onto the stage 11. Adjusting the position of the locking element 12 via the thread allows for precise control of the clamping force on the wire. Based on the wire's thickness, material, and other characteristics, the clamping force can be precisely adjusted to a suitable level, ensuring the wire is securely fixed and will not loosen during observation, while also preventing damage to the wire due to excessive clamping force. Furthermore, the threaded connection is less prone to loosening or failure during long-term use, ensuring reliable wire fixation even after repeated use.

[0036] In other embodiments, instead of using a screw connection, a connecting hole communicating with the receiving groove 110 can be provided on the stage 11. A sealing ring is provided in the connecting hole, and the locking member 12 passes through the sealing ring. When the locking member 12 is inserted, the sealing ring will undergo elastic deformation due to compression, tightly fitting between the surface of the locking member 12 and the inner wall of the connecting hole, so that the locking member 12 will not easily displace under the action of external force.

[0037] More specifically, such as Figures 1-3 As shown, the locking member 12 includes a screw 121 and a first buffer pad 122 connected to each other. The screw 121 is screwed to the stage 11, and the wire can be clamped between the first buffer pad 122 and the inner wall of the receiving groove 110. When clamping the wire, the first buffer pad 122 can prevent the screw 121 from directly applying rigid pressure to the wire, preventing the wire surface from being scratched or indented.

[0038] In this embodiment, the inner wall of the receiving groove 110 is provided with a second buffer pad, and the wire can be clamped between the first buffer pad 122 and the second buffer pad to avoid friction and compression of the wire by the inner wall of the receiving groove 110, so that the surface of the wire is scratched or indented.

[0039] More specifically, such as Figure 2 As shown, the locking component 12 also includes a screw head 123, which is connected to the end of the screw 121 away from the buffer pad 122. The screw head 123 provides the operator with a larger force application area, making it easier and less strenuous for the operator to turn the screw 121.

[0040] Specifically, such as Figure 1 and Figure 4 As shown, the rotating component 22 includes a universal ball 221 and a connecting rod 222 connected to each other. The connecting rod 222 is connected to the stage 11, and the base 21 is provided with a mounting groove. The universal ball 221 is hinged to the mounting groove. The universal ball 221 can rotate in all directions within the mounting groove, thereby allowing the stage 11 to be adjusted in multiple dimensions, and thus adjusting the wire break to an observation angle perpendicular to the microscope objective.

[0041] In this embodiment, the connecting rod 222 is screwed to the platform 11.

[0042] More specifically, such as Figure 1 , Figure 5 and Figure 6 As shown, the base 21 includes a seat body 211 and a housing 212. The seat body 211 has a groove 2110, and the housing 212 is fitted onto the outer periphery of the seat body 211, forming an installation groove on the groove 2110. The seat body 211 and the housing 212 are manufactured as independent components, avoiding the complex processing technology of integrally forming the installation groove, thus reducing manufacturing difficulty. Furthermore, during assembly, the operator can first place the universal ball 221 into the groove 2110, and then fit the housing 212 onto the seat body 211 to complete the installation of the universal ball 221, making assembly simple and efficient.

[0043] More specifically, the housing 212 is provided with a limiting channel, and along the direction toward the groove 2110, the inner wall of the limiting channel gradually moves away from the axis of the housing 212. The setting of the inner wall of the limiting channel can not only adapt to the movement trajectory of the universal ball 221 when it rotates at different angles, but also play a limiting role while ensuring the flexible rotation of the universal ball 221, preventing the universal ball 221 from rotating excessively or falling out.

[0044] More specifically, the end of the housing 212 furthest from the base 211 is provided with a clearance opening, which connects to the limiting channel, allowing the connecting rod 222 to extend into the clearance opening. With this clearance opening, the operator can first connect the platform 11 to the connecting rod 222, then place the omnidirectional ball 221 into the groove 2110, and finally fit the housing 212 onto the outer periphery of the base 211 through the clearance opening, simplifying installation. Without the clearance opening, the operator would need to first place the omnidirectional ball 221 into the groove 2110, then fit the housing 212 onto the outer periphery of the base 211, and then connect the connecting rod 222 to the platform 11. In this case, the connection space between the connecting rod 222 and the platform 11 is limited, making the installation process complex and difficult.

[0045] More specifically, such as Figure 5 As shown, the base 211 includes a chassis 2111 and a support 2112 connected to each other. A groove 2110 is provided in the support 2112, and a housing 212 is fitted around the outer periphery of the support 2112 and abuts against the chassis 2111. This structural design makes the various parts of the base 211 relatively independent. When the base 211 needs to be cleaned, the housing 212 can be more easily disassembled to clean the support 2112 and the groove 2110, removing accumulated dust, impurities, etc. At the same time, the independent components also make it easier to find and handle problems during inspection and maintenance, improving maintenance efficiency.

[0046] Specifically, the fixing member 23 is screwed onto the base 21. When it is necessary to lock the rotating member 22, the fixing member 23 is screwed on to make it fit tightly against the rotating member 22 to achieve locking. When it is necessary to adjust the angle of the wire, the fixing member 23 is screwed on in the opposite direction to allow the rotating member 22 to rotate freely. The operation is simple.

[0047] In other embodiments, a slot may be provided on the base 21, and a corresponding buckle may be installed on the fixing member 23. When locking is required, the buckle is engaged with the corresponding slot, so that the fixing member 23 and the rotating member 22 are tightly fitted to achieve locking, thereby restricting the rotation of the rotating member 22.

[0048] In this embodiment, as Figure 1 As shown, the receiving groove 110 is a U-shaped groove that extends from one side of the stage 11 and continues to the opposite side, with the two opposite groove walls parallel and perpendicular to the bottom surface of the groove. Because the groove walls are perpendicular to the bottom surface of the groove, the position and angle of the guide wire can be more clearly determined during observation, facilitating precise focusing and adjustment, and improving the accuracy and efficiency of observation.

[0049] In this embodiment, the steps for observing the wire using a clamping device are as follows:

[0050] Step 1: Place the wire into the receiving groove 100. By rotating the locking member 12, adjust the distance between it and the groove wall of the receiving groove 110 to clamp the wire and prevent it from falling off as the stage 11 moves.

[0051] Step 2: Place the clamping device under the stereomicroscope. First, loosen the fixing part 23 of the angle adjustment component 2. By adjusting the angle of the rotating part 22, change the direction of the stage 11 so that the field of view to be observed by the wire is perpendicular to the objective lens. Then tighten the fixing part 23 to maintain the current angle of the stage 11.

[0052] Step 3: Observe and photograph the broken section of the conductor. If you need to switch the field of view, repeat steps 1 and 2 above until the entire broken section has been observed.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
