An upper stabilizing plate 18 that contacts the top of the material plate 3 to be tested is fixedly installed on the L-shaped connecting plate 17. The lower stabilizing plate 15 and the upper stabilizing plate 18 are both located on the side of the clamp 7 away from the contact plate 8. The lower stabilizing plate 15 and the upper stabilizing plate 18 are adjustable so that they can be as close to the side as possible during use to simulate the strength of actual use.

[0044] The driving mechanism includes multiple teeth 26 and a support plate 27. The teeth 26 are fixedly mounted on the impact slide bar 23.

The output end of the speed sensor 42 is connected to the roller shaft 39. The distance measuring mechanism can detect the length of the material plate 3 to be detected. It can be operated manually and is relatively flexible.

[0046] It is worth noting that the circuits, electronic components, and modules involved in this invention are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this invention does not involve improvements to the software and methods.

[0047] The working principle of the metal material mechanical property testing clamping machine provided by this invention is as follows:

[0048] This solution also includes an electrical control cabinet, which is installed on the equipment. During use, each piece of electrical equipment can be started and operated separately through the electrical control cabinet. The power connection method of each piece of electrical equipment is an existing mature technology and is well known to those in the field, so it will not be described in detail here.

[0049] In this invention, to simulate actual strength, the material to be tested 3, made of metal material, is made into a plate. Then, the material to be tested 3 is placed on the lower support 10. Then, according to the normal strength of its metal material, the position of the lower stabilizing plate 15 is adjusted. The length of the material to be tested 3 between the lower stabilizing plate 15 and the clamp 7 is the test deformation length, which can simulate the strength of actual use to a large extent. During adjustment, the guide slide plate 13 is slid along the guide slide 5, the guide rod 12 and the linkage rod 14. After adjustment, the guide slide plate 13 and the linkage rod 14 are fixed with bolts.

[0050] Then, start the second cylinder 9 to lower the U-shaped upper frame 2, so that the upper pressure seat 11 presses against the material plate 3 to be tested. When the upper pressure seat 11 contacts the material plate 3 to be tested, stop the second cylinder 9. At this time, pull the L-shaped connecting plate 17 and the upper stabilizing plate 18, so that the L-shaped connecting plate 17 slides along the sliding port 16 and the upper stabilizing plate 18 corresponds to the lower stabilizing plate 15. Then, install the connecting side piece 20 on the side of the lower stabilizing plate 15 and the U-shaped seat 19 with bolts. Then, start the second cylinder 9 again to press the upper pressure seat 11 and the upper stabilizing plate 18 against the material plate 3 to be tested, thus completing the fixing of the material plate 3 to be tested.

[0051] During testing, hydraulic cylinder 4 is activated, causing its output rod to retract and move the linkage plate 6, clamp 7, and contact plate 8 synchronously. The contact plate 8 clamps and tests the material plate 3 to be tested. In use, the linkage plate 6 moves the linkage rod 14, guide slide plate 13, and lower stabilizing plate 15 synchronously. The lower stabilizing plate 15 moves the upper stabilizing plate 18 synchronously through the U-shaped seat 19 and connecting side plate 20, maintaining a stable distance between the contact plate 8 and the lower and upper stabilizing plates 15 and 18, which can also largely prevent the material plate 3 to be tested from bending and bouncing.

[0052] During use, pressure sensor 21 can detect pressure in various locations. When the pressure of a pressure sensor 21 is abnormal, a bending problem occurs at that location.

[0053] In use, this device not only adopts conventional hydraulic methods but also impact detection methods. During impact detection, the output rod of cylinder 4 is removed from the linkage plate 6. Then, the output rod of cylinder 4 is retracted, and then the electric telescopic rod 29 is activated, so that the L-shaped assembly plate 30 drives the motor 31 and gear 32 to slide upward along the adjustment port 28 until the gear 32 disengages from the teeth 26. At this time, the impact slide rod 23 is disengaged, and the energy storage spring 25 rebounds to push the impact block 24 and the impact slide rod 23 out of the guide cylinder 22. When the impact block 24 hits the clamp 7, the contact plate 8 slides and impacts the side of the material plate 3 to be tested. The anti-disengagement block 33 can limit the impact slide rod 23. When the energy is recharged, the electric telescopic rod 29 is retracted, so that the gear 32 re-engages with the teeth 26. After the motor 31 is restarted, each component can be returned to its original position.

[0054] During use, the upper stabilizing plate 18 can be slid independently, so that the roller 40 in the notch 34 slides along the material plate 3 to be tested, which will cause the speed sensor 42 to rotate and output an electrical signal, thereby measuring the length of the material plate 3 to be tested. The material plate 3 to be tested can be placed horizontally and moved by hand during the length measurement.

[0055] Compared with related technologies, the metal material mechanical property testing clamping machine provided by the present invention has the following beneficial effects:

It offers good stability during use, allows for control of the testing length, and can largely simulate the strength under actual use conditions. The clamping mechanisms can apply pressure to both sides of the material plate 3 to achieve testing. The operation is simple, and the detachable hydraulic cylinder 4 and linkage plate 6 facilitate the use of subsequent force storage mechanisms. This dual-purpose design provides greater flexibility and meets different needs. Hydraulic cylinder 9 is used to raise and lower the U-shaped upper frame 2, controlling the downward pressure height. The lower support 10 and upper pressure seat 11 support the middle of the material plate 3, fixing a large area in the middle. The lower stabilizing plate 15 and upper stabilizing plate 18 are adjustable, allowing for [further details needed for accurate translation]. The adjustable linkage rod 14 can control the distance between the lower stabilizing plate 15 and the contact plate 8 by being as close to the side as possible to simulate the intensity of actual use. The connecting side plate 20 and the U-shaped seat 19 can connect the lower stabilizing plate 15 and the contact plate 8 to achieve linkage between the lower stabilizing plate 15 and the contact plate 8. The pressure sensor 21 can detect the position of deformation of the material plate 3 to be tested and the detection pressure, and the data is relatively direct. The energy storage mechanism can impact the clamping seat 7 when released, so that the material plate 3 to be tested can be impact tested. There are multiple detection methods. The driving mechanism can store the impact slide rod 23 and other components in the energy storage mechanism to make it slide. It does not affect the normal detection when stored and does not conflict with the clamping detection when in use. The distance measuring mechanism can detect the length of the material plate 3 to be tested. The operation can be manual and is relatively flexible.
