Detailed implementation manners

[0020] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0022] Next, refer to Figures 1 to 12 Describe the quick-disassembly and quick-assembly spring wire tensile testing device provided according to some embodiments of the present application.

[0023] As Figure 1 、 Figure 3As shown, the quick-disassembly and assembly spring steel wire tension testing device provided in accordance with some embodiments of the present application includes a tensile testing machine 100, a buffer mechanism 200, a fixing mechanism 300, a locking mechanism 400, and a trigger mechanism 500. The tensile testing machine 100 includes two clamps, each of which includes: a buffer mechanism 200, which is provided on the tensile testing machine 100 and is used to provide a buffering force for the spring steel wire; a fixing mechanism 300, which is connected to the buffer mechanism 200 and cooperates with the buffer mechanism 200 to clamp and fix the spring steel wire; a locking mechanism 400, which is provided on the buffer mechanism 200 and limits the fixing mechanism 300; and a trigger mechanism 500, which is provided on the buffer mechanism 200 and is triggered by the buffer mechanism 200 to move the trigger mechanism 500, thereby releasing the limit of the fixing mechanism 300 by the locking mechanism 400.

[0024] In this embodiment, the spring steel wire is clamped and fixed by cooperating with the fixing mechanism 300 and the buffer mechanism 200, and the tensile testing machine 100 provides a stable tensile output to perform a tensile test on the spring steel wire. The two clamps are respectively arranged on both sides of the tensile testing machine 100 and are symmetrically distributed. After the fixing mechanism 300 clamps and fixes the spring steel wire, it will be placed in the corresponding position. At this time, the locking mechanism 400 limits and locks the fixing mechanism 300. After the tensile test is completed, the spring steel wire breaks. At this time, the buffer mechanism 200 loses the clamping force and moves, and the trigger mechanism 500 moves accordingly, and drives the locking mechanism 400 to move, so that the locking mechanism 400 releases the lock on the fixing mechanism 300, so that the fixing mechanism 300 is separated from the buffer mechanism 200, and the spring steel wire can be quickly withdrawn, realizing the rapid disassembly of the spring steel wire. After completing a tensile test, a new spring steel wire can be quickly replaced for the next test, which significantly improves work efficiency.

[0025] In some possible embodiments, such as Figure 1 As shown, the tensile testing machine 100 includes: a base 110; a loading frame 120, which is arranged on the base 110; a beam 130, which is arranged on the loading frame 120 and can move relative to the loading frame 120; a support platform 140, which is arranged on the base 110; and two clamps are respectively arranged at the bottom of the beam 130 and the top of the support platform 140.

[0026] In this embodiment, the base 110 is the basic support structure of the tensile testing machine 100. The loading frame 120 is arranged on the base 110, and provides support and guidance for the cross beam 130 through the loading frame 120, so that the cross beam 130 can move precisely in the vertical direction. The support table 140 is arranged on the base 110 and is opposite to the cross beam 130. Two clamps are respectively arranged at the bottom of the cross beam 130 and the top of the support table 140. The spring wire is clamped on the two clamps. By driving, the cross beam 130 moves upward along the loading frame 120. As the cross beam 130 rises, the upper clamp applies an upward pulling force to the spring wire, and the spring wire gradually elongates. The tensile testing machine 100 monitors the magnitude of the pulling force and the elongation of the spring wire in real time to achieve the tensile force detection of the spring wire.

[0027] In some possible embodiments, such as Figures 2 - 6 shown, the buffer mechanism 200 includes: a fixed frame 210 connected to the cross beam 130; two buffer columns 220 respectively arranged on both sides of the fixed frame 210, and each buffer column 220 penetrates the fixed frame 210; two limit blocks 221 respectively arranged on each buffer column 220; two support frames 230 respectively fixedly arranged at the bottom of each buffer column 220, and each support frame 230 includes an arc-shaped groove and a support shaft; two first springs 240 respectively arranged on each buffer column 220; a mounting frame 231 arranged between the two support frames 230; a fixed V-shaped block 250 fixedly connected to the mounting frame 231, and the fixed V-shaped block 250 has a V-shaped receiving cavity.

[0028] In this embodiment, in the initial state, the fixed frame 210 contacts the limit block 221, the first spring 240 is in a natural state, and the spring wire is in the receiving cavity of the fixed V-shaped block 250. When the cross beam 130 moves upward to apply a pulling force to the spring wire, the spring wire is subjected to an upward pulling force, and the cross beam 130 will drive the fixed frame 210 to move upward. When the cross beam 130 applies a pulling force again, the buffer column 220 and the support frame 230 move upward with the fixed frame 210. At this time, the first spring 240 is stretched to detect the pulling force of the spring wire. When the pulling force exceeds the limit that the spring wire can bear, the spring wire will break. At this time, the fixed V-shaped block 250 loses the clamping force on the spring wire and will generate a certain impact force on the first spring 240. Under the elastic force of the first spring 240, the buffer column 220 will move upward relative to the position of the fixed frame 210, and the support frame 230 and the fixed V-shaped block 250 will also generate an upward displacement. At this time, the triggering mechanism 500 is activated.

[0029] In some possible embodiments, such as Figures 6 - 8As shown in the figure, the fixing mechanism 300 includes: a rotating shaft 310, which is disposed through the support shafts of the two support frames 230; a rotating frame 320, which is rotatably connected to the rotating shaft 310; a limiting column 330, which is disposed on the rotating frame 320, and the limiting columns 330 are distributed in the arc-shaped grooves of the corresponding support frames 230; two torsion springs 340, which are respectively disposed on both sides of the rotating frame 320, and each torsion spring 340 is disposed between the rotating frame 320 and the corresponding support frame 230, a screw 360, which is disposed on the rotating frame 320; a movable V-shaped block 350, which is disposed at the end of the screw 360, the movable V-shaped block 350 has a V-shaped receiving cavity, and the movable V-shaped block 350 cooperates with the fixed V-shaped block 250; a handwheel 370, which is disposed at one end of the screw 360 away from the movable V-shaped block 350.

[0030] In this embodiment, in the initial state, the rotating frame 320 is in an inclined state. At this time, the torsion spring 340 is in a natural state. The operator rotates the rotating frame 320 along the rotating shaft 310 by pushing, so that the rotating frame 320 changes from an inclined state to a vertical state. During the rotation process, the torsion spring 340 is twisted to store elastic potential energy. When the rotating frame 320 rotates to the vertical state, the locking mechanism 400 is pushed to limit and fix the limiting column 330. At this time, the rotating frame 320 remains in this position. At the same time, the operator rotates the handwheel 370 to move the screw 360 axially, driving the movable V-shaped block 350 to approach the fixed V-shaped block 250, clamping the spring wire. The tensile testing machine 100 applies a tensile force to the spring wire for tensile testing. When the tensile force exceeds the bearing limit of the spring wire, it breaks. At this time, the buffer mechanism 200 will trigger the trigger mechanism 500, and the trigger mechanism 500 causes the locking mechanism 400 to move upward. The upward movement of the locking mechanism 400 will release the limit on the limiting column 330. The torsion spring 340 releases elastic potential energy, causing the rotating frame 320 to rotate along the rotating shaft 310. At the same time, the limiting column 330 moves along the arc-shaped groove in the support frame 230, driving the movable V-shaped block 350 to rotate. At this time, the movable V-shaped block 350 moves away from the fixed V-shaped block 250, canceling the limit on the spring wire. The operator can directly extract the wire, reducing the complex operation of manual unlocking and improving work efficiency.

[0031] In some possible embodiments, as Figures 8 - 10 shown, the locking mechanism 400 includes: a lifting column 410, which is disposed on the mounting frame 231; a limiting ring 411, which is disposed on the lifting column 410; a locking column 420, which is disposed at the end of the lifting column 410, and the bottom surface of the locking column 420 is inclined; a fixed contact block 430, which is disposed at the end of the lifting column 410 away from the locking column 420, and the fixed contact block 430 has a plurality of anti-slip lines; a second spring 440, which is disposed outside the lifting column 410, and the second spring 440 is disposed between the limiting ring 411 and the fixed contact block 430.

[0032] In this embodiment, in the initial state, the second spring 440 is in a compressed state. At this time, the limiting ring 411 contacts the mounting bracket 231. When the operator pushes the rotating frame 320, the limiting post 330 inside the rotating frame 320 contacts the inclined surface of the locking post 420. Due to the existence of the inclined surface, the limiting post 330 exerts an obliquely upward force on the locking post 420, which is decomposed into a vertically upward force and a horizontally directed force. The vertically upward component force causes the locking post 420 to overcome the elastic force of the second spring 440, driving the lifting post 410 to move upward. The second spring 440 is stretched and stores elastic potential energy. As the rotating frame 320 moves, when the rotating frame 320 exceeds the vertical position of the locking post 420, the second spring 440 releases the elastic potential energy, pushing the lifting post 410 downward, so that the locking post 420 returns to below the movement path of the limiting post 330 again to limit the locking post 420. When the spring wire breaks, the buffer mechanism 200 triggers the trigger mechanism 500, and the trigger mechanism drives the fixed contact block 430 to move upward. The fixed contact block 430 drives the locking post 420 to move upward together through the lifting post 410, and then the locking post 420 contacts to limit the limiting post 330.

[0033] In some possible embodiments, as Figure 9 、 Figure 11 shown, the trigger mechanism 500 includes: a piston cylinder 510 disposed on the mounting bracket 231; a piston rod 520 disposed on one side of the top of the piston cylinder 510; a connecting block 530 fixedly connected to the fixed bracket 210; a support groove 540 disposed on the top of the piston cylinder 510. The support groove 540 includes the piston rod 520 that can move relative to the piston cylinder 510. A movable contact block 550 is disposed on the support groove 540. The movable contact block 550 includes a plurality of anti-slip textures. The movable contact block 550 cooperates with the fixed contact block 430; a third spring 560 is disposed between the movable contact block 550 and the support groove 540; a baffle 570 is disposed outside the support groove 540.

[0034] In this embodiment, in the initial state, the piston rod 520 at the bottom of the connecting block 530 is in the extended state, and the piston rod 520 at the bottom of the support groove 540 is in the contracted state. When the spring wire breaks, the mounting bracket 231 will move upward relative to the position of the fixed bracket 210, resulting in a shortening of the position between the mounting bracket 231 and the fixed bracket 210. Since the piston cylinder 510 is fixed to the mounting bracket 231 and the connecting block 530 is fixed to the fixed bracket 210, the connecting block 530 moves relative to the piston cylinder 510, causing the piston rod 520 at the bottom of the connecting block 530 to contract. Since a sealed air chamber is formed inside the piston cylinder 510, the volume of the air chamber is changed by the movement of the piston rod 520, thereby achieving the transmission of force. As a result, the piston rod 520 at the bottom of the support groove 540 will extend, and then the support groove 540 can move upward relative to the position of the piston cylinder 510, driving the movable contact block 550 to move upward together. The movable contact block 550 contacts the fixed contact block 430, so that the movable contact block 550 can drive the fixed contact block 430 to move upward. The fixed contact block 430 drives the locking column 420 to move upward through the lifting column 410, releasing the restriction of the locking column 420 on the limiting column 330 and the rotating frame 320. Thus, the movable V-shaped block 350 is separated from the fixed V-shaped block 250. At this time, when the support groove 540 moves upward further, the locking column 420 cannot move upward due to the restriction of the mounting bracket 231, so the movable contact block 550 will separate from the fixed contact block 430. As a result, the second spring 440 resumes its elastic deformation, causing the locking column 420 to return to its initial position, preparing for the next detection.

[0035] In some possible embodiments, as Figure 1 shown, the spring wire is vertically arranged between the fixed V-shaped block 250 and the movable V-shaped block 350, and the fixed V-shaped block 250 and the movable V-shaped block 350 are linearly distributed along the center line of the tensile testing machine 100.

[0036] In this embodiment, the spring wire is vertically arranged between the fixed V-shaped block 250 and the movable V-shaped block 350, and the fixed V-shaped block 250 and the movable V-shaped block 350 are linearly distributed along the center line of the tensile testing machine 100, which can ensure that the spring wire mainly bears axial tension during the tensile test, avoid the generation of eccentric loads, and at the same time ensure that the spring wire is in an absolutely vertical state, reducing the interference of bending stress, so as to more accurately measure the tensile properties of the spring wire.

[0037] When the quick-disassembly spring wire tensile testing device is operating, in the initial state, the rotating frame 320 is in an inclined state and the torsion spring 340 is in a natural state. The operator rotates the rotating frame 320 along the rotating shaft 310 to a vertical state, and elastic potential energy is stored by torsion inside the torsion spring 340. When the rotating frame 320 rotates to the vertical state, the limiting column 330 inside the rotating frame 320 contacts the inclined surface of the locking column 420. Due to the existence of the inclined surface, the limiting column 330 exerts an upwardly inclined force on the locking column 420, driving the lifting column 410 to move upward, and the second spring 440 is stretched to store elastic potential energy. As the rotating frame 320 moves, when the rotating frame 320 exceeds the vertical position of the locking column 420, the second spring 440 releases the elastic potential energy, pushing the lifting column 410 to move downward, so that the locking column 420 returns to below the movement path of the limiting column 330, limiting the locking column 420 and keeping the rotating frame 320 in this position. At the same time, the operator rotates the handwheel 370 to move the screw rod 360 axially, driving the movable V-shaped block 350 closer to the fixed V-shaped block 250 to clamp the spring wire vertically between them. Moreover, the fixed V-shaped block 250 and the movable V-shaped block 350 are distributed in a straight line along the center line of the tensile testing machine 100, so that the spring wire is in an absolutely vertical state. In the tensile test, the tensile testing machine 100 drives the cross beam 130 to move upward along the loading frame 120. The cross beam 130 drives the fixed frame 210 to move upward, and the buffer column 220 and the support frame 230 move upward with the fixed frame 210. The first spring 240 is stretched. At this time, the fixture at the bottom of the cross beam 130 exerts an upward force on the spring wire, and the spring wire gradually elongates. The tensile testing machine 100 monitors the magnitude of the tensile force on the spring wire in real time to achieve the tensile test. When the tensile force exceeds the limit that the spring wire can bear, the spring wire breaks. At this time, the fixed V-shaped block 250 and the movable V-shaped block 350 lose the clamping force on the spring wire, generating a certain impact force on the first spring 240. Under the elastic force of the first spring 240, the buffer column 220 will move upward relative to the position of the fixed frame 210, and the support frame 230 and the fixed V-shaped block 250 also move upward accordingly. Since the piston cylinder 510 is fixed on the mounting frame 231 and the connecting block 530 is fixed on the fixed frame 210, the upward movement of the mounting frame 231 relative to the fixed frame 210 causes the distance between the two to shorten. Then the connecting block 530 moves relative to the piston cylinder 510, causing the piston rod 520 at the bottom of the connecting block 530 to contract, changing the volume of the air chamber inside the piston cylinder 510 for force transmission. Thus, the piston rod 520 at the bottom of the support groove 540 elongates, and the support groove 540 moves upward relative to the piston cylinder 510, driving the movable contact block 550 to move upward together. The movable contact block 550 contacts the fixed contact block 430, and the movable contact block 550 drives the fixed contact block 430 to move upward through the anti-slip texture. The fixed contact block 430 drives the locking column 420 to move upward through the lifting column 410, thus releasing the limit of the locking column 420 on the limiting column 330. At this time, the torsion spring 340 releases the elastic potential energy,Rotate the rotating frame 320 along the rotating shaft 310. At the same time, the limiting column 330 moves along the arc-shaped groove in the support groove 540, driving the movable V-shaped block 350 to rotate. The movable V-shaped block 350 moves away from the fixed V-shaped block 250, canceling the limit on the spring steel wire. The operator can directly take out the broken spring steel wire, completing a test process. Through the linkage design of the trigger mechanism 500 and the locking mechanism 400, this device can automatically release the limit on the fixing mechanism 300 after the spring steel wire breaks, separating the movable V-shaped block 350 from the fixed V-shaped block 250. The operator does not need to manually perform complex unlocking operations and can quickly withdraw the spring steel wire, achieving the rapid disassembly of the spring steel wire and significantly improving work efficiency.
