Description

Technical Field

[0001] The present application relates to the technical field of tension detection devices, and in particular to a stainless steel micro-wire tension detection device. Background Art

[0002] Stainless steel microwires have the advantages of good electrical conductivity, thermal conductivity, high strength, high elasticity, wear resistance, corrosion resistance and thermal stability in oxidizing atmospheres. They are widely used in textile, aerospace, military, medical, biochemical, modern industry, modern civil, petrochemical and other industries. In the medical industry, in order to ensure that the strength of the stainless steel microwires meets the requirements and the elastic properties can meet the standards, a tensile testing device is needed to test the tensile strength of the stainless steel microwires.

[0003] The existing stainless steel microwire tension detection device generally includes a frame structure (base, column and beam), a clamping assembly, a transmission mechanism and a force measurement system. Before the stainless steel microwire is subjected to tension detection, the two ends of the stainless steel microwire need to be fixed by a clamping assembly, and then the upper clamping assembly is driven by a power mechanism to stretch the stainless steel microwire, so that the force measurement system measures the tension during the stretching process. However, due to the small diameter of the stainless steel microwire, when the clamping assembly clamps the end of the stainless steel microwire, the clamping force of the clamping assembly can easily cause the clamped part of the end of the stainless steel microwire to deform. In the subsequent stretching process, the stainless steel microwire can easily break from the position where it is clamped and deformed, thereby affecting the accuracy of the stainless steel microwire tension detection device for the stainless steel microwire; and when the upper and lower clamping assemblies clamp the two ends of the stainless steel microwire, it is difficult to ensure that the two ends of the stainless steel microwire are on the same vertical line. During the clamping process of the stainless steel microwire, once the stainless steel microwire is skewed, it will seriously affect the accuracy of the detection result. Summary of the invention

Example

[0026] Embodiment 2 is a further improvement on embodiment 1.

[0027] The difference from the first embodiment is that, please refer to Figure 3-Figure 5 A plurality of mounting grooves 407 arranged in a circular array are provided on the fixed shaft 405 near the end of the transverse groove of the insertion groove 406, and the mounting groove 407 is located between the two side frames 402. A connecting hole I 408 connecting the plurality of mounting grooves 407 is provided at the bottom end of the mounting groove 407. A tension spring 409 is fixedly connected to the bottom end of the mounting groove 407, and a support column 410 is fixedly connected to the other end of the tension spring 409, and one end of the support column 410 is slidably sealed and installed in the mounting groove 407, and the other end of the support column 410 extends out of the mounting groove 407. 0 is filled with transmission fluid in the mounting groove 407 and the connecting hole I 408 at the bottom; a slide groove 412 is provided on the inner side wall of the fixing plate 403 close to the mounting groove 407, a limit block 413 is fixedly installed on the side wall at the bottom of the slide groove 412, a support spring 414 is fixedly connected to the middle position of the bottom of the slide groove 412, and the other end of the support spring 414 is fixedly connected to an extrusion block 415, one end of the extrusion block 415 is slidably sealed and installed in the slide groove 412, and the other end of the extrusion block 415 extends out of the slide groove 412, and the end of the extrusion block 415 extending out of the slide groove 412 is an inclined surface.

[0028] See also Figure 5 A plurality of slots 411 are provided at one end of the support column 410 extending out of the mounting slot 407 ; when the stainless steel microwire is wound from the fixed shaft 405 to the support column 410 , the slots 411 facilitate positioning of the stainless steel and prevent the stainless steel microwire from slipping off the end of the support column 410 .

[0029] See also Figure 3 , Figure 6 and Figure 7The fixing plate 403 is close to the inner side wall of the transverse groove of the insertion groove 406, and a plate storage groove 416 is opened. The bottom end of the plate storage groove 416 is fixedly connected to a plurality of return springs 417, and the other ends of the plurality of return springs 417 are fixedly connected to the same reinforcing plate 418. One end of the reinforcing plate 418 is slidably sealed and installed in the plate storage groove 416, and the other end of the reinforcing plate 418 extends out of the plate storage groove 416; please refer to Figure 4 and Figure 5 A connecting hole II 420 is provided in the middle position of the bottom end of the slide groove 412, and the connecting hole II 420 is used to connect the slide groove 412 at the bottom end of the extrusion block 415 and the storage plate groove 416 at the bottom end of the reinforcement plate 418. The slide groove 412 at the bottom end of the extrusion block 415 and the storage plate groove 416 at the bottom end of the reinforcement plate 418 are filled with transmission fluid; when the extrusion block 415 is against the limit block 413, the reinforcement plate 418 will not slide out of the storage plate groove 416, and one end of the reinforcement plate 418 extending out of the storage plate groove 416 just straightens above the fixed shaft 405.

[0030] See also Figure 6 , the position of the storage plate slot 416 is higher than the top position of the fixed shaft 405; when the reinforcing plate 418 of the storage plate slot 416 slides to the top of the fixed shaft 405, it is ensured that the fixed shaft 405 and the stainless steel microwire on the fixed shaft 405 will not hinder the movement of the reinforcing plate 418.

[0031] An elastic strip is fixedly embedded at the bottom of one end of the reinforcing plate 418 extending out of the storage plate slot 416; when the reinforcing plate 418 extends to the fixed shaft 405 wrapped with the stainless steel microwire, the elastic strip on the reinforcing plate 418 is tightly against the stainless steel microwire to prevent damage to the stainless steel microwire, and the elastic strip on the reinforcing plate 418 is tightly against the stainless steel microwire on the fixed shaft 405.

[0032] The tension spring 409 is always in a stretched state, and the tension spring 409 in the stretched state generates a pulling force on the support column 410, so that the lengths of several support columns 410 extending out of the mounting slot 407 are the same; the support spring 414 and the return spring 417 are always in a stretched state, and the pulling force of the support spring 414 and the return spring 417 is used to balance the positions of the extrusion block 415 and the reinforcement plate 418, and when there is no external force, the extrusion block 415 and the reinforcement plate 418 are prevented from affecting the winding of the stainless steel microwire by the fixed shaft 405.

[0033] The working principle of the second embodiment of the present invention is as follows: See also Figure 1-Figure 7In the process of the stainless steel microwire being wound onto the fixed shaft 405, the stainless steel microwire wound onto the fixed shaft 405 gradually moves toward the support column 410 until the stainless steel microwire is pressed into the card slot 411 at the end of the support column 410, so that the support column 410 moves into the mounting slot 407. In the process of the fixed shaft 405 rotating, more and more support columns 410 are squeezed into the mounting slot 407. The squeezed support columns 410 push the transmission fluid in the mounting slot 407 through the connecting hole I 408 into the mounting slot 407 in the un-squeezed support column 410, pushing the support column 410 in the un-squeezed mounting slot 407 to move to the outside of the mounting slot 407. In the process of the fixed shaft 405 driving the support column 410 to rotate, the extended support column 410 The support column 410 protruding from the installation groove 407 pushes the extrusion block 415 until the extension of the support column 410 is greater than that of the extrusion block 413, and the extrusion block 415 is pushed to abut against the limit block 413, and the support column 410 can no longer cross the extrusion block 415 and continue to rotate. At this time, the position of one end of the stainless steel microwire in the slot 411 on the support column 410 is determined. After the other end of the stainless steel microwire is fixed in the same way, the position of the other end of the stainless steel microwire in the slot 411 on the support column 410 is also determined. At this time, the positions of the ends of the stainless steel microwire on the upper and lower fixed shafts 405 are determined, ensuring that the ends of the stainless steel microwire on the upper and lower fixed shafts 405 are on the same vertical line, thereby avoiding the skewness of the stainless steel microwire affecting the accuracy of the detection result.

[0034] Moreover, in the process that the extrusion block 415 is squeezed by the support column 410 to move toward the limit block 413, the extrusion block 415 squeezes the transmission fluid in the slide groove 412, and the transmission fluid enters the storage plate groove 416 through the connecting hole II 420. The transmission fluid entering the storage plate groove 416 pushes the reinforcing plate 418 to move toward the outside of the storage plate groove 416. When the extrusion block 415 is against the limit block 413, the protruding end of the reinforcing plate 418 is just stuck on the stainless steel microwire wrapped around the fixed shaft 405, and the stainless steel microwire wrapped around the fixed shaft 405 is fixed to prevent the looseness of the wrapped stainless steel microwire from affecting the fixation of the end; during the tensile test, the reinforcing plate 418 at the upper end of the fixed shaft 405 supports the fixed shaft 405 to prevent the fixed shaft 405 from bending when the stainless steel microwire is stretched.
