DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 1-Figure 6 As shown, in this embodiment, a high-temperature alloy fracture stress detection device includes a detection platform 1, the top of the detection platform 1 is fixedly connected to a shell 2, the top of the shell 2 is fixedly installed with a hydraulic cylinder 23, the output end of the hydraulic cylinder 23 extends to the interior of the shell 2 and is fixedly connected with a detection head 24, a moving groove 3 is opened on the top of the detection platform 1, a moving plate 6 is slidably connected to the top of the detection platform 1, a transmission component is arranged inside the moving groove 3, the transmission component is used to drive the moving plate 6 to move, the top of the moving plate 6 is slidably connected to two L-shaped clamping plates 7, a slide groove 12 is opened on the top of the moving plate 6, an adjustment component is arranged inside the slide groove 12, the adjustment component is used to drive the two L-shaped clamping plates 7 to move, a stress detector 19 is fixedly installed on the top of the detection platform 1, and a strain gauge 20 is arranged on one side of the stress detector 19.

[0024] When testing the high-temperature alloy, the high-temperature alloy is placed between the two L-shaped clamps 7, and the adjustment component is operated according to the specific specifications of the high-temperature alloy, so that the two L-shaped clamps 7 clamp and fix the high-temperature alloy. After the high-temperature alloy is fixed, the staff uses the handheld strain gauge 20 to fix the strain gauge 20 on the outside of the high-temperature alloy, and then drives the clamped high-temperature alloy into the interior of the housing 2 through the transmission component, and drives the detection head 24 to apply pressure to the surface of the high-temperature alloy by the hydraulic cylinder 23. After the high-temperature alloy is deformed by the pressure, the data of the high-temperature alloy fracture stress detection is transmitted to the stress detector 19 through the strain gauge 20 to complete the detection of the high-temperature alloy fracture stress. In this way, the adjustment component is convenient for fixing according to the actual specifications of the high-temperature alloy, preventing the high-temperature alloy from moving during the detection process, thereby affecting the detection results. At the same time, the displacement component is convenient for the staff to move the high-temperature alloy to the interior of the housing 2 after installing the strain gauge 20, so as to improve the efficiency of the high-temperature alloy fracture stress detection work.

[0025] like Figure 1-Figure 6 As shown, the transmission assembly includes a threaded rod 4, which is rotatably connected between the inner walls of the movable groove 3, and the outer side of the threaded rod 4 is threadedly connected to a movable block 18, and the top of the movable block 18 is fixedly connected to the movable plate 6. A servo motor 5 is fixedly installed on one side of the detection platform 1, and the output end of the servo motor 5 extends to the interior of the movable groove 3 and is fixedly connected to the threaded rod 4.

[0026] The threaded rod 4 is driven by the servo motor 5 to rotate inside the movable groove 3, and the movable block 18 is further driven to slide between the inner walls of the movable groove 3, so that the movable plate 6 moves with the movable block 18, thereby facilitating the high-temperature alloy to enter the interior of the shell 2 for stress detection through the movable block 18.

[0027] like Figure 1-Figure 6 As shown, the adjustment assembly includes a bidirectional screw rod 13, which is rotatably connected between the inner walls of the slide groove 12, and the outer side of the bidirectional screw rod 13 is threadedly connected to two sliders 15, and the tops of the two sliders 15 are respectively fixedly connected to the two L-shaped clamps 7, and one side of the movable plate 6 is rotatably connected to the second handle 14, one end of the second handle 14 extends to the inside of the slide groove 12 and is fixedly connected to the bidirectional screw rod 13, one side of the L-shaped clamp 7 is fixedly connected to the fixed plate 8, and the internal thread of the fixed plate 8 is connected to the adjusting screw 9, one end of the adjusting screw 9 is rotatably connected to the pressure plate 10, one side of the pressure plate 10 is slidably connected to the L-shaped clamp 7, and the other end of the adjusting screw 9 is fixedly connected to the first handle 11, an auxiliary groove 16 is opened on one side of the L-shaped clamp 7, and an auxiliary block 17 is fixedly connected to one side of the pressure plate 10, and the outer side of the auxiliary block 17 is slidably connected to the inner wall of the auxiliary groove 16.

[0028] By placing the high-temperature alloy between the two L-shaped clamps 7, the two L-shaped clamps 7 are driven to move toward each other by turning the second handle 14 and clamp the high-temperature alloy from both sides. When the shape of the high-temperature alloy is not standard, the first handle 11 can be turned and the adjusting screw 9 can be used to drive the pressure plate 10 to press down on the top of the high-temperature alloy to further strengthen the fixation of the high-temperature alloy, making it convenient for the staff to strengthen the fixation of the high-temperature alloy and prevent the high-temperature alloy from moving during the detection process, thereby affecting the detection results.

[0029] like Figure 1-Figure 6 As shown, one side of the stress detector 19 is fixedly connected to a wire box 21, and a connecting wire 22 is arranged inside the wire box 21. The two ends of the connecting wire 22 are fixedly connected to the stress detector 19 and the strain gauge 20 respectively.

[0030] The staff manually fixes the strain gauge 20 on the outside of the high-temperature alloy, so that the strain gauge 20 can be used to detect the detection status of the high-temperature alloy in real time. The detection data can be transmitted to the stress detector 19 through the connecting wire 22.

[0031] The utility model provides a high-temperature alloy fracture stress detection device, and the specific working principle is as follows: when performing high-temperature alloy detection, the high-temperature alloy is placed between two L-shaped clamps 7, and the second rotating plate 14 is rotated according to the specifications of the high-temperature alloy, so that the two L-shaped clamps 7 clamp and fix the high-temperature alloy. When the shape of the high-temperature alloy is irregular, the pressure plate 10 is moved on one side of the L-shaped clamp 7 by rotating the first rotating disk 11 and assists in the fixation of the high-temperature alloy. After the high-temperature alloy is fixed, the staff uses a handheld strain gauge 20 to fix the strain gauge 20 on the outside of the high-temperature alloy, and then drives the threaded rod 4 to rotate inside the moving groove 3 through the servo motor 5, so that the moving block 18 drives the high-temperature alloy fixed by the L-shaped clamp 7 to enter the inside of the shell 2, and then uses the hydraulic cylinder 23 to drive the detection head 24 to apply pressure to the surface of the high-temperature alloy. After the high-temperature alloy is deformed by the pressure, the data of the high-temperature alloy fracture stress detection is transmitted to the stress detector 19 through the strain gauge 20 to complete the detection of the high-temperature alloy fracture stress.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
