Description

Technical Field

[0001] This application relates to the field of measuring devices, and more particularly, to a device for assisting in measuring elongation. Background Art

[0002] Elongation is an important parameter in the detection of the mechanical properties of materials. The quality of elongation determines the usage conditions of materials and has a significant impact on the service life of materials.

[0003] When measuring the elongation of a fractured specimen with a conventional tensile test device, after the specimen breaks into two sections, it is necessary to measure the total length of the spliced specimen to determine the elongation. Due to the presence of grain misalignment and slip at the fracture surface, the interface is uneven. When manually measuring the gauge length with a caliper, external forces need to be applied from both ends. Since the fracture surface is uneven, the fracture is not easily closed. In addition, circular specimens are prone to relative rotation, which brings great difficulties to manual measurement and the work efficiency is very low. Moreover, during the measurement of elongation, vibrations and the like may cause slightly gaps at the fracture coincidence, resulting in errors in the measurement of elongation.

[0041] Hereinafter, the present disclosure will be described in detail with reference to the drawings and in combination with the embodiments.

[0042] Refer to Figures 1-4, A device for assisting in measuring elongation, comprising a bottom plate 1, a processing table 2, a fixing block 3, and a clamping assembly; the processing table 2 is fixedly arranged on the bottom plate 1, and a groove 4 for placing a fractured specimen is opened at the upper end of the processing table 2; the fixing block 3 is fixedly arranged on the bottom plate 1 and one end abuts against the processing table 2, and the clamping assembly includes a support block 5, a push rod 6, and a driving member 7; the support block 5 is fixedly arranged on the bottom plate 1, a through cavity 8 is opened on the support block 5, the push rod 6 is arranged through the through cavity 8 and is slidably matched with the through cavity 8, and the driving member 7 is arranged on the support block 5.

[0043] An internal threaded hole 9 is opened on the support block 5, and the driving member 7 includes a screw rod 10, a knob 11, and an annular plate 12; one end of the screw rod 10 is inserted into the internal threaded hole 9 and is threadedly matched with the internal threaded hole 9, the knob 11 is fixedly arranged at the other end of the screw rod 10, the annular plate 12 is arranged on the screw rod 10, and one end of the annular plate 12 abuts against the push rod 6. A slot 13 is opened on the push rod 6, and one end of the annular plate 12 is inserted into the slot 13 and abuts against the push rod 6.

[0044] A convex ring 14 is arranged on the annular plate 12, and an annular groove 15 for inserting the convex ring 14 is opened on the push rod 6. Through the arrangement of the convex ring 14, a limiting effect is exerted on the push rod 6.

[0045] The device for assisting in measuring elongation further includes a stop block 16, a spring 17, and a limit block 18; the stop block 16 is slidably arranged on the processing table 2, one end of the spring 17 is connected to the stop block 16, and the other end is connected to the fixing block 3. The limit block 18 is fixedly arranged on the processing table 2 and is located between the stop block 16 and the fixing block 3. A through hole for the spring 17 to pass through is opened on the limit block 18. Through the arrangement of the stop block 16, one end of the fractured specimen is abutted and fixed. Through the arrangement of the limit block 18, a limiting effect is exerted on the spring 17 to prevent the spring 17 from bending due to an excessive length in the radial direction.

[0046] A first slider 19 is arranged on the stop block 16 and is inserted into the groove 4.

[0047] Second sliders 20 are arranged at both ends of the stop block 16, and sliding grooves 21 matched with the second sliders 20 are opened on the processing table 2.

[0048] The specific operation method is as follows:

[0049] Place the two fractured specimens in the groove 4. One end of one fractured specimen will abut against the stop block 16, and the spring 17 is compressed to generate a rebound force to make the stop block 16 tightly abut against one end of the fractured specimen. Rotate the driving knob 11 to make the screw 10 rotate. Since the annular plate 12 is inserted into the slot 13 and abuts against the ejector rod 6, when the annular plate 12 rotates, it pushes the ejector rod 6 to move towards the fractured specimen, so that the ejector rod 6 abuts against one end of the other fractured specimen. This prevents the fractured specimen from rotating, facilitating the measurement of the length of the fractured specimen with a scale at the end. Thus, the fractured specimen is fixed, the fracture surfaces of the specimens are closely combined, facilitating the measurement of the size of the fractured specimen, saving time and effort, and improving the measurement accuracy. Determine the final elongation by comparing the total length of the spliced specimens after fracture with the original length of the specimens.
