Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of wire detection, and particularly relates to a wire detection device. BACKGROUND

[0002] Before existing wires are put into use, the wires need to be detected for fatigue resistance by a wire detection device. The wire detection device needs to repeatedly bend the wire, and the fatigue resistance of the wire is determined by counting the cumulative bending times when the wire is broken. The existing wire detection device comprises a positioning structure for fixing the wire and a bending structure rotatably arranged. The wire is repeatedly bent by the bending structure driving the wire. The existing bending structure comprises a rotatably arranged fixing seat, two bending pieces arranged on the fixing seat and used for clamping the wire, threaded holes arranged at both ends of the fixing seat, and a moving bolt threadedly connected with the threaded holes and used for moving the bending pieces. In the wire positioning stage, the wire is fixed to the positioning structure, and the two moving bolts are adjusted to move the bending pieces. When one bending piece is moved, the user needs to operate the other bending piece. At this time, the user cannot calculate the distance between the two bending pieces, and cannot know whether the initial positions of the two moving bolts are the same, so that the moving distances of the two bending pieces are different, the wire is inclined during clamping, and additional torque and bending moment are generated when the wire is bent, so that the stress distribution at the bent part of the wire is uneven, the real bending performance of the wire cannot be accurately reflected, and the detection accuracy of the wire is affected. Even if the user uses both hands to operate the moving bolts, the upper end of the wire is arranged between the two bending pieces, and the upper end of the wire is inclined due to gravity, so that the wire is offset. At this time, the moving bolts are tightened, so that the bent part of the wire has an inclination, the bending angle of the wire is affected, and the user cannot adjust the wire because the user needs to operate the moving bolts, so that the detection accuracy of the wire is affected.

[0016] Due to the adoption of the above technical scheme, the application has the following beneficial effects:

[0017] 1、The application sets the pushing part, the pushing part comprises two clamping pieces, sets the driving piece, the driving piece drives the two clamping pieces to move reversely synchronously, the two bending pieces are located between the two clamping pieces, the clamping piece drives the bending piece to move reversely synchronously, on one hand, the user only needs to control the driving piece to clamp the wire, thereby reducing the operation burden of the user, on the other hand, the two clamping pieces limit the movement of the bending piece, so that the two bending pieces can move synchronously, the distance of the bending piece is accurately controlled, the wire is prevented from deviating in the clamping process, and because the two clamping pieces move reversely synchronously, the distance problem of the two bending pieces is not needed to worry about during the installation of the bending piece, the position adjustment of the bending piece is automatically realized during the movement of the clamping piece, the detection efficiency is improved, and the wire detection precision is ensured.

[0018] 2、As a preferred embodiment of the present application, the positioning section extends from the self-fixing section towards the side away from the rotating member, providing operating space for the user to facilitate the user to install and dismount the bending member. The assembly hole provides an installation position for the bending member, facilitating the installation and dismounting of the bending member. The clamping member is movably arranged in the assembly hole, and the assembly hole provides a common positioning reference for the clamping member and the bending member, ensuring that they can maintain a relatively accurate positional relationship after installation. The threads of the threaded holes of the two clamping members are opposite and are threadedly connected with the driving member. When the driving member is rotated, the two clamping members will simultaneously move in opposite directions (one approaches the driving member, the other moves away from the driving member, or vice versa), thereby symmetrically clamping the bending member, allowing the bending member to be subjected to uniform clamping force, avoiding deformation or loosening of the bending member due to uneven force, ensuring the stability and reliability of the installed bending member, and improving the working performance and accuracy of the wire detection device. Moreover, when the driving member is rotated, due to the opposite threads of the threaded holes of the two clamping members, regardless of the initial placement position of the bending member, the clamping member will automatically push the bending member to the middle position during the process of gradually approaching the bending member, achieving the centering effect. At the same time, the movement pattern and final position of the two clamping members are consistent each time, ensuring that repeated and consistent centering effects can be achieved when installing the bending member multiple times, avoiding centering deviations caused by human operation or other factors, and improving the inspection accuracy. Within the adjustable range of the two clamping members, different specifications and types of bending members can be replaced, enabling the detection of different specifications of wires, and improving the versatility of the detection device.

[0019] 3、As a preferred embodiment of the present application, the bending member includes a limiting section and an abutting section, improving the installation convenience of the bending member. At the same time, the abutting section is at least partially exposed from the assembly hole, allowing the bending part to be outside the assembly hole, facilitating the worker to directly observe the state of the bending part during the operation or maintenance of the wire detection device. The bending part being arranged outside the assembly hole can avoid further stress concentration caused by bending operations near the assembly hole, which is beneficial to improve the reliability and service life of the bending structure.

[0020] 4、As a preferred embodiment of the present application, the installation slot can guide the movement of the clamping member, ensuring the movement accuracy of the clamping member. The thread connection of the driving member and the threaded hole cooperates to limit the displacement of the clamping member in the assembly hole. Even if subjected to external force or vibration, the clamping member can maintain a relatively stable position under the constraint of the installation slot, thereby ensuring the clamping effect of the bending member and the stability of the bending structure.

[0021] Further, by setting the guide section, the positioning section and the pushing section, the functional partition of the clamping piece is realized, the threaded hole is arranged in the positioning section, on the one hand, the pushing force of the driving piece to the positioning section can be transmitted to the pushing section, so that the pushing section can more directly drive the bending piece to move, ensuring the accuracy and stability of the movement of the bending piece, on the other hand, the threaded hole is arranged in the positioning section, so that the pushing section can be responsible for pushing the bending piece to move, determining the function of the pushing section, avoiding the mutual interference of functions, and improving the accuracy of the clamping piece driving the bending piece to move.

[0022] 5、As a preferred embodiment of the present application, the wire is guided by the guide assembly, which facilitates the installation and disassembly of the wire and improves the positioning accuracy of the wire. The guide assembly is movably arranged on the base, so that the distance between the guide assembly and the bending structure can be adjusted. On the one hand, the support strength provided for the wire is improved, so that the wire can be accurately bent at the bending position. On the other hand, the flexible and variable distance setting allows the wire detection device to adapt to the bending needs of wires of various lengths and specifications.

[0023] Further, by setting the guide hole, one end of the guide hole points to the two bending pieces, and the other end points to the positioning structure, so that the guide hole can guide the wire to the space between the two bending pieces or to the positioning structure, improving the efficiency of wire clamping and disassembly. In one embodiment, the guide piece is made of elastic material, and the extension section can provide corresponding support to avoid the wire from being deviated in angle at the bending position under the action of the bending piece, affecting the bending accuracy.

[0024] Further, by setting the guide piece, the guide piece is provided with a tapered hole, the large end of the tapered hole faces the bending structure, and the small end is arranged opposite to the guide hole, so that after the wire passes through the bending structure, it naturally penetrates into the guide hole through the guide of the tapered hole, improving the convenience of wire installation, avoiding the need for the user to guide the wire through the guide hole by hand, and improving the detection efficiency. By setting the mounting hole to be sleeved on the extension section, the installation and disassembly of the guide piece are facilitated.

[0025] 6、As a preferred embodiment of the present application, by setting the connecting rod, one end of the connecting rod is rotatably connected with the eccentric position of the rotating disc, and the other end drives the rotating piece to rotate, the connecting rod converts the rotation of the rotating disc into oscillation, realizing the reciprocating rotation of the rotating piece. The rotation of the rotating disc drives the rotating piece to rotate in an orderly manner through the connecting rod, reducing the impact and vibration in the movement process, and ensuring the stability of the wire detection device in the running process.

[0026] Further, the host drives the rotating disc to rotate through the output shaft, one end of the connecting rod is connected to the eccentric position of the rotating disc, and the other end is rotatably connected with the driving gear, so as to realize the misalignment connection. When the rotating disc does circular motion, the connecting rod can convert it into reciprocating motion and accurately transmit it to the bending structure, so as to drive the bending structure to realize the bending of the wire. The misalignment arrangement avoids energy loss and jamming phenomenon in the power transmission process, ensures that the power is stably and efficiently transmitted from the driving mechanism to the bending structure, and ensures the smooth operation of the whole detection process. At the same time, the conflict between the driving mechanism and the bending structure in space is avoided, so that the wire detection device can integrate more functional components in limited space, improve the integration and compactness of the wire detection device.

Figure 3 In the application, the predetermined direction is the horizontal direction in Figure 3 .

[0052] In this application, the moving mechanism 72 can drive the clamping mechanism 71 to move in any of the following embodiments:

[0053] Implementation method one: such as Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the fixed base 51 includes a fixed section 511 detachably mounted on the rotating member 4 and a positioning section 512 extending from the fixed section 511 toward the side opposite to the rotating member 4. The positioning section 512 has an assembly hole 513 for mounting the bent member 52. The clamping member 71 is movably mounted in the assembly hole 513 and has a threaded hole 711. The threads of the threaded holes 711 of the two clamping members 71 are opposite. The surface of the driving member 72 has an external thread, and the driving member 72 is threadedly connected to the threaded hole 711. The driving member 72 is rotatably mounted on the positioning section 512, and the positioning section 512 has a limiting member (not shown in the figure) that cooperates with the driving member 72. Figure 3 As shown, the limiting member prevents the driving member 72 from undergoing horizontal displacement. The limiting member can be a bearing fixed to the positioning section 512, and the bearing is connected to the driving member 72. The assembly hole 513 includes a hole along a preset direction ( Figure 3 Two side walls (not shown in the attached diagram) are arranged opposite each other in the horizontal direction. Each side wall is provided with a limiting member, and the two limiting members are arranged opposite each other along a preset direction, such as... Figure 3 , Figure 5 As shown, the positioning section 412 is provided with an operation hole 514 that connects to the assembly hole 513. The active member 72 extends through the operation hole 514 in a preset direction and is connected to two limiting members. The active member 72 is at least partially exposed on the outer surface of the positioning section 412 to facilitate operation by the user.

[0054] The positioning section 512 extends from the fixing section 511 to the side away from the rotating member 4, which provides an operating space for the user to install and dismount the bending member 52. The assembly hole 513 provides a mounting position for the bending member 52, which facilitates the installation and dismounting of the bending member 52. The clamping member 71 is movably arranged in the assembly hole 513, which provides a common positioning reference for the clamping member 71 and the bending member 52, ensuring that they can maintain a relatively accurate positional relationship after installation. The threads of the threaded holes 711 of the two clamping members 71 are opposite and are threadedly connected with the driving member 72. When the driving member 72 is rotated, the two clamping members 71 will simultaneously move in opposite directions (one approaches the driving member 72, and the other moves away from the driving member 72, or vice versa), thereby symmetrically clamping the bending member 52, so that the bending member 52 is subjected to uniform clamping force, avoiding deformation or loosening of the bending member 52 due to uneven force, ensuring the stability and reliability of the installed bending member 52, and improving the working performance and accuracy of the wire detection device. Moreover, when the driving member 72 is rotated, due to the opposite threads of the threaded holes 711 of the two clamping members 71, regardless of the initial placement position of the bending member 52, the clamping member 71 will automatically push the bending member 52 to the middle position during the process of gradually approaching the bending member 52, achieving the centering effect.

Within the adjustable range of the two clamping members 71, different specifications and types of bending members 52 can be replaced, achieving detection of different specifications of wires, and improving the versatility of the detection device.

[0057] Embodiment 1: As Figure 4 、 Figure 6 、 Figure 10As shown, the bending piece 52 includes a limiting segment 521 for abutting against the positioning segment 512 and an abutting segment 522 arranged at the assembly hole 513, the abutting segment 522 extends towards the side close to the positioning structure 6 and at least partially exposes the assembly hole 513, and the abutting segment 522 towards the end of the positioning structure 6 is used for bending the wire.

[0058] By arranging the bending piece 52 to include the limiting segment 521 and the abutting segment 522, the installation convenience of the bending piece 52 is improved, and by arranging the abutting segment 522 to at least partially expose the assembly hole 513, the bending part is outside the assembly hole 513, which facilitates the staff to directly observe the state of the bending part during the operation of the wire detection device or maintenance, and the bending part arranged outside the assembly hole 513 can avoid further stress concentration caused by bending operation near the assembly hole 513, which is beneficial to improve the reliability and service life of the bending structure 3.

[0060] In the first embodiment, the movement of the clamping piece 71 can be any one of the following embodiments:

[0061] Embodiment 3: As shown in Figure 5 , Figure 6 , Figure 7 As shown, the assembly hole 513 includes two hole walls 5131 extending along a predetermined direction, and the hole walls 5131 are provided with mounting grooves 5132 which cooperate with the clamping piece 71.

[0062] The movement of the clamping piece 71 can be guided by the mounting grooves 5132 to ensure the movement accuracy of the clamping piece 71, and the threaded connection of the driving piece 72 and the threaded hole 711 together limits the displacement of the clamping piece 71 in the assembly hole 513, so that the clamping piece 71 can maintain a relatively stable position under the constraint of the mounting grooves 5132 even if subjected to external force or vibration, thereby ensuring the clamping effect of the bending piece 52 and the stability of the bending structure 3.

[0063] Embodiment 4: This embodiment 4 is not shown, the hole wall is provided with a positioning protrusion, and the clamping piece is provided with a mounting groove.

[0064] In embodiment 3, the clamping piece 71 can be arranged in any one of the following specific examples:

[0065] Specific example 1: as shown in Figure 5 , Figure 6 , Figure 7 The clamping piece 71 includes a guide section 712 provided with a mounting groove 5132, a positioning section 512 extending from the guide section 712 towards the side away from the mounting groove 5132, and a pushing section 714 connected with the positioning section 512 and abutting against the bending piece 52, and a threaded hole 711 is arranged in the positioning section 512. Further, the pushing section 714 is also provided with a positioning groove 715 cooperating with the bending piece 52. During installation, the bending piece 52 is placed in the assembly hole 513, and the initial positioning of the bending piece 52 is realized by moving the bending piece 52 to cooperate with the positioning groove 715, and then the wire is placed. The clamping piece 71 is moved by the driving piece 72, the pushing section 714 pushes the bending piece 52, and synchronous movement is realized to ensure that the bending piece 52 moves synchronously and clamps the wire together.

[0066] By arranging the guide section 712, the positioning section 512 and the pushing section 714, the functional division of the clamping piece 71 is realized. The threaded hole 711 is arranged in the positioning section 512, which can facilitate the transmission of the pushing force of the driving piece 72 to the pushing section 714, so that the pushing section 714 can more directly drive the bending piece 52 to move, ensuring the accuracy and stability of the movement of the bending piece 52. On the other hand, the threaded hole 711 is arranged in the positioning section 512, so that the pushing section 714 can be responsible for pushing the bending piece 52 to move, determining the function of the pushing section 714, avoiding the mutual interference of functions, and improving the accuracy of the movement of the clamping piece 71 driving the bending piece 52.

[0070] The guide component 82 guides the wire, facilitating its installation and removal and improving its positioning accuracy. The guide component 82 is movably mounted on the base 81, allowing the distance between the guide component 82 and the bending structure 3 to be adjusted. This improves the support strength provided to the wire, enabling precise bending at the bending point. Furthermore, the flexible and variable distance setting allows the wire detection device to adapt to bending requirements for various wire lengths and specifications.
