Description

Technical Field

[0001] The utility model belongs to the technical field of steel strength detection, and relates to a steel strength detection device with a quick clamping fixture. Background Art

[0002] Steel strength testing is a critical step in ensuring steel quality and safe application. Strength testing primarily assesses steel's tensile, compressive, bending, and shear properties to ensure its reliability in various engineering applications. The testing process typically includes sampling, sample preparation, testing, and data analysis. After steel sampling, stable clamping is a key step in ensuring the accuracy of test results during steel strength testing. Failure to achieve stable clamping of the steel may lead to the following problems:

[0003] Unstable clamping can affect the positioning and alignment of steel during testing. Improper alignment can produce eccentric loading when applied, leading to biased test results. This eccentric loading can cause some areas of the steel to experience higher stress than required by the test, while other areas experience lower stress, making it difficult to accurately assess the overall strength of the material. Therefore, a steel strength testing device with a quick-clamping fixture is urgently needed to address this issue. Utility Model Content

[0028] A group of upper pressure holding seats 150 for clamping the upper end of the steel to be tested is provided at the lower end of the upper electric cylinder 140, and a group of lower pressure holding seats 160 for clamping the lower end of the steel to be tested is provided at the lower end of the same vertical horizontal plane as the upper pressure holding seats 150. The upper end of the steel to be tested can be clamped by using the upper pressure holding seats 150.

[0029] A group of pressure sensors 170 for detecting the pressure borne by the lower pressure holder 160 are provided at the lower end of the lower pressure holder 160, and a group of data wires 180 for transmitting pressure data to an external control output device are provided on the left side of the pressure sensor 170.

The front side of the base 190 is provided with a group of operating buttons 200 for controlling the extension and retraction of the telescopic rod 130 and the pressure of the upper electric cylinder 140.

[0031] The lower pressure holding seat 160 includes an outer clamping seat 16a, an inner clamping seat 16b, an internal pressure guide rod 16c and a side support seat 16d. The outer clamping seat 16a, the inner clamping seat 16b and the side support seat 16d are each provided with two groups, and the front cross-section of the two groups of outer clamping seats 16a is arranged in a trapezoidal structure. Each group of outer clamping seats 16a is provided with a group of inner clamping seats 16b for clamping the lower end of the steel to be tested on the inner side.

[0034] See also Figure 1-Figure 4 , as the first embodiment of the present utility model: In order to solve the problem that unstable clamping will affect the positioning and centering of steel during the test process, if the steel cannot be correctly centered, eccentric loads will be generated when subjected to force, which will cause deviations in the test results. Eccentric loads will cause steel to withstand higher stresses than the actual test requirements in some areas, while other areas have lower stresses, making it impossible to accurately assess the overall strength of the material. The staff will place the steel sample to be tested inside the lower holding seat 160, and clamp it by two groups of outer clamping seats 16a and two groups of inner clamping seats 16b. Then the staff will start the telescopic rod 130 to drive the connecting seat 210 and the upper electric cylinder 140 to move downward, and make the upper holding seat 150 press the upper end of the steel to be tested. Then the staff will start the upper electric cylinder 140, and use the upper electric cylinder 140 to press the upper holding seat 150 to apply pressure to the upper end of the steel to be tested, and then the pressure of the steel to be tested will be borne by the pressure sensor 170 through the internal pressure guide rod 16c inside the lower holding seat 160. Since a group of data wires 180 for transmitting pressure data with an external control output device is provided on the left side of the pressure sensor 170, its pressure is output to the external output device through the data guide, thereby obtaining the pressure bearing condition of the steel.
