When the device performs different tests on an object, it is necessary to disassemble and install the corresponding test parts, which increases the working time of the device. In view of this, in-depth research was conducted to address the above problems, which led to this case. Utility Model Content

[0004] The purpose of this invention is to provide an electronic universal tensile testing machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electronic universal tensile testing machine, comprising a support, a storage tank, and a threaded rod. The support has storage tanks on both sides inside, and the storage tanks have a threaded rod inside. The upper part of the threaded rod is connected to the inner wall of the support through a bearing. A servo motor is installed below the threaded rod. A threaded block is installed on the outer side of the threaded rod, and a connecting block is installed on the outer side of the threaded block. The connecting blocks on both sides are installed on both sides of the experimental structure.

[0006] The experimental structure includes a first storage box, an electric slide rail, and a sliding column. Connecting blocks are installed on both sides of the first storage box. Electric slide rails are installed on both sides inside the first storage box. A sliding column is installed on the outer side of the electric slide rail. The lower part of the sliding column passes through a second sliding groove and connects to a clamping column. The clamping column is located inside the first storage box. Second rubber blocks are installed on the inner walls of the clamping columns on both sides. A first automatic telescopic rod is installed on the inner side of the left clamping column. A pressing block is installed below the first automatic telescopic rod. A second storage box is installed inside the support. Second automatic telescopic rods are installed on both sides inside the second storage box. Connecting columns are provided on the outer sides of the second automatic telescopic rods. The upper part of the connecting column passes through a third sliding groove and connects to a pressing plate. A fixing block is installed above the pressing plate. First rubber blocks are installed on the inner sides of the pressing plates on both sides.

[0007] Preferably, the bracket and the storage tank are integrated, and the threaded rod and the bearing are rotatably connected.

[0008] Preferably, the threaded rod is driven to the servo motor, and the threaded rod is threaded to the threaded block.

[0009] Preferably, the connecting blocks are fixedly connected to the threaded block and the first storage box, and the connecting blocks are slidably connected to the first sliding groove.

[0010] Preferably, the sliding columns are fixedly connected to the electric slide rail and the clamping column, and the sliding columns are L-shaped.

[0011] Preferably, the sliding column and the second sliding groove are slidably connected, and the second sliding groove and the first storage box are integrally formed.

[0012] Preferably, the first automatic telescopic rod is fixedly connected to the pressing block and the left clamping column, and the clamping column is tightly fitted to the second rubber block.

[0013] Preferably, the second storage box is fixedly connected to the bracket and the second automatic telescopic rod, and the connecting column is fixedly connected to the second automatic telescopic rod and the extrusion plate.

[0015] Preferably, the extrusion plate and the first rubber block are tightly fitted together, and the extrusion plate and the fixing block are fixedly connected.

[0016] Compared with existing technologies, the beneficial effects of this utility model are:

[0017] When in use, the user places the raw steel bar between two extrusion plates. The second automatic telescopic rod is activated, causing the connecting column to slide inside the third slide groove. The connecting column, along with the extrusion plates, clamps and fixes the lower end of the raw steel bar. Next, the servo motor is activated, causing the threaded rod to rotate inside the bearing. Through the threaded connection between the threaded rod and the threaded block, the threaded rod drives the connecting block connected to the threaded block to slide inside the first slide groove, allowing the connecting block to slide the first storage box downwards. When the top of the raw steel bar reaches the bottom of the first storage box, the servo motor stops running. The electric slide rails on both sides are then activated, causing the sliding column to slide inside the second slide groove. The sliding column, along with the clamping column, clamps the upper end of the raw steel bar. The second and first rubber blocks increase the friction between the device and the raw steel bar. Then, the servo motor resets, allowing the raw steel bar to undergo a tensile test.

[0018] Case 2: During use, the user places the raw material plate on top of the two extrusion plates, and the fixing block blocks one side of the raw material plate to fix its position. Next, the electric slide rail connected to the left sliding column is activated. The electric slide rail drives the left sliding column to slide inside the second slide groove on the left. The left sliding column drives the clamping column connected to the left clamping column to slide. When the left clamping column slides to the middle position, the first automatic telescopic rod is activated to drive the pressing block to slide downwards, so that the bottom of the pressing block is aligned with the middle position above the raw material plate. Then, the servo motor is activated to run the same steps as in Case 1, driving the pressing block connected to the first automatic telescopic rod to perform bending detection on the raw material plate.

[0019] When processing objects, the device can perform tensile and bending tests on the objects as needed, improving the applicability of the device. At the same time, it reduces the disassembly time of the parts to be tested, and can directly perform tensile and bending tests on the objects to be processed, thereby increasing the working time of the device.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Please see Figure 1-5 This utility model provides a technical solution for an electronic universal tensile testing machine: an electronic universal tensile testing machine includes a support 1, a storage tank 2 and a threaded rod 3. The support 1 has storage tanks 2 on both sides inside, and the storage tank 2 has a threaded rod 3 inside. The upper part of the threaded rod 3 is connected to the inner wall of the support 1 through a bearing 4. A servo motor 5 is installed below the threaded rod 3. A threaded block 6 is installed on the outer side of the threaded rod 3. A connecting block 8 is installed on the outer side of the threaded block 6. The connecting blocks 8 on both sides are installed on both sides of the experimental structure 9.

[0031] Experimental structure 9 includes a first storage box 901, an electric slide rail 902, and a sliding column 903. Connecting blocks 8 are installed on both sides of the first storage box 901. Electric slide rails 902 are installed on both sides inside the first storage box 901. Sliding columns 903 are installed on the outer sides of the electric slide rails 902. The lower part of the sliding column 903 passes through a second sliding groove 904 and connects to a clamping column 905. The clamping column 905 is located inside the first storage box 901. Second rubber blocks 915 are installed on the inner walls of the clamping columns 905 on both sides. The left clamping column 905... A first automatic telescopic rod 906 is installed on the inner side of the bracket 1. A pressing block 907 is installed below the first automatic telescopic rod 906.

The electric slide rail 902 drives the left sliding column 903 to slide inside the left second slide groove 904. The left sliding column 903 drives the clamping column 905 connected to the left clamping column 905 to slide. When the left clamping column 905 is in the middle position of the sliding device, the user starts the first automatic telescopic rod 906 to drive the pressing block 907 to slide downwards, so that the bottom of the pressing block 907 is aligned with the middle position above the raw material plate 10. Then, the user starts the servo motor 5 to run the same steps as in Case 1, driving the pressing block 907 connected to the first automatic telescopic rod 906 to perform bending detection on the raw material plate 10.

[0034] When processing objects, the device can perform tensile and bending tests on the objects as needed, improving the applicability of the device.
