Stress detector with high stability

Abstract

This utility model discloses a stress detector with high stability, including a housing with legs installed at the bottom and a door at one end. An X-ray stress detector is mounted on the bottom of a mounting plate. A limiting structure is installed at the bottom of the worktable, including a fixed plate and guide rods penetrating the bottom ends of both ends of the fixed plate. This utility model utilizes a fixed plate at the bottom of the worktable, with the fixed plate and threaded rods forming a threaded connection. This allows a rotating block to be gripped and rotated, causing the threaded rod to rotate. The rotation of the threaded rod causes it to move, which in turn moves the limiting plate. The moving limiting plate clamps the product being tested, preventing displacement during testing and ensuring more stable testing results. The guide rods penetrating the fixed plate further prevent displacement of the limiting plate, thus achieving the goal of enhancing the stability of the stress detector.

Description

Technical Field

[0001] This utility model relates to the field of stress detection technology, and in particular to a stress detector with high stability. Background Technology

[0002] A stress detector is a specialized instrument used to measure the distribution, magnitude, and direction of stress inside or on the surface of an object. By detecting stress, the stress state of a material or structure can be assessed, preventing failures such as fractures and deformations caused by stress concentration. In structures such as mechanical parts, bridges, and pressure vessels, detecting stress distribution can identify potential structural hazards in advance and avoid accidents. It can also determine whether a material is within a safe stress range by detecting residual stress or working stress inside the material. Stress detectors have wide applications in many fields such as materials science, mechanical manufacturing, aerospace, and civil engineering.

[0003] To address this, patent publication CN220490263U discloses a handheld stress detector, comprising a strain gauge body, a resistance strain gauge, wires, a socket, and a base plate. The strain gauge body has an anti-detachment mechanism at its bottom, which includes an L-shaped anti-detachment block, a T-shaped shaft, a limiting structure, and an auxiliary positioning structure. The L-shaped anti-detachment block is rotatably mounted on the bottom surface of the strain gauge body, with its right end extending to the bottom surface of the base plate. This invention improves upon existing indentation stress detectors by incorporating an anti-detachment mechanism at the bottom of the strain gauge device. This mechanism effectively prevents the socket and base plate from detaching, ensuring the stability of the wire connection between the strain gauge body and the resistance strain gauge. Even if the wire is accidentally pulled during testing due to external factors, it will not detach, guaranteeing the overall stability of the handheld stress detector.

[0004] The aforementioned handheld stress tester can effectively prevent the socket and base plate from detaching, thereby ensuring the stability of the connection between the strain gauge body and the resistance strain gauge. Even if the wire is accidentally pulled due to external factors during the test, it will not detach, ensuring the overall stability of the handheld stress tester. However, during use, the tested item may shift, affecting the testing efficiency and stability. Therefore, the item needs to be fixed during testing. Utility Model Content

[0005] The purpose of this invention is to provide a stress detector with high stability, in order to solve the problem that existing stress detectors are difficult to improve in terms of detection stability.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a stress detector with high stability, including a housing;

[0007] The bottom of the box is equipped with support legs, one end of the box is equipped with a door, the bottom of the box is equipped with a workbench, and the bottom of the workbench is equipped with a control panel.

[0008] The control board is equipped with a display screen at the bottom, and a telescopic structure is installed at one end of the workbench. A mounting plate is installed at the bottom of the telescopic structure, and an X-ray stress detector is installed at the bottom of the mounting plate.

[0009] The bottom of the workbench is equipped with a limiting structure, which includes a fixing plate installed at the bottom of the workbench, and guide rods passing through the bottom ends of both ends of the fixing plate.

[0010] In use, the product can first be positioned, and then the X-ray stress detector can be controlled by the control board. When X-rays penetrate the surface of the material, the change in the interplanar spacing will cause the diffraction peak to shift. The stress value can be obtained by calculating the shift through the microcontroller built into the control board. The value can be displayed on the screen.

[0011] Furthermore, a protective structure is installed at the bottom of the workbench. The protective structure includes a baffle installed at the top of the workbench, a rotating shaft installed on the inner side of the baffle, a connecting rod installed on one side of the rotating shaft, a first protective plate installed on one side of the connecting rod, and a second protective plate installed on one side of the connecting rod. The protective structure can protect the control panel.

[0012] Furthermore, a locking block is provided on one side of the second protective plate, and a locking groove is provided on one side of the first protective plate. The second protective plate and the first protective plate form a locking structure, which facilitates disassembly.

[0013] Furthermore, a limiting plate is installed on one side of the guide rod, a threaded rod is installed on one side of the limiting plate, and a rotating block is installed on one side of the threaded rod. The limiting plate can limit the product.

[0014] Furthermore, the outer side wall of the threaded rod is uniformly provided with external threads, and the inner side wall of the fixing plate is uniformly provided with internal threads that cooperate with the external threads. The threaded rod and the fixing plate are threadedly connected, and the rotation of the threaded rod can drive the limiting plate to move.

[0015] Furthermore, the telescopic structure includes a second telescopic rod installed at the bottom of the worktable, and a fixing screw installed on one side of the second telescopic rod. A first telescopic rod is installed at the bottom of the second telescopic rod. The telescopic structure can adjust the height of the X-ray stress detector.

[0016] Furthermore, a slider is provided at the bottom end of the first telescopic rod, and a sliding groove is provided inside the second telescopic rod. The first telescopic rod and the second telescopic rod constitute a sliding structure, and the first telescopic rod can slide inside the second telescopic rod.

[0017] The stress detector with high stability provided by this utility model has the following advantages: during use, the limiting structure can limit the product being tested to prevent the product from shifting during testing; the height of the X-ray stress detector can be adjusted by the telescopic structure to adapt to different situations; and the control board can be protected by the protective structure.

[0018] By installing a fixed plate at the bottom of the workbench, the fixed plate and the threaded rod form a threaded connection. The rotating block can be gripped and rotated to drive the threaded rod to rotate. The rotation of the threaded rod will drive the threaded rod to move, and the movement of the threaded rod will drive the limit plate to move. The movement of the limit plate can clamp the product to be tested in the middle to prevent the product from shifting during testing, making the testing effect more stable. The guide rod passes through the fixed plate and can prevent the limit plate from shifting, thereby achieving the purpose of improving the stability of the stress tester.

[0019] By installing a second telescopic rod at the bottom of the workbench, the second telescopic rod and the first telescopic rod form a sliding structure. The first telescopic rod can slide inside the second telescopic rod. The sliding of the first telescopic rod can adjust the height of the top plate and the X-ray stress detector, allowing the X-ray stress detector to adapt to different situations. When the housing is fixed to the first telescopic rod, the fixing screws can be tightened to fix the first telescopic rod, thereby achieving the purpose of facilitating the adjustment of the height of the X-ray stress detector.
