Description

Technical Field

[0001] This utility model relates to the technical field of stress detection, and in particular to a stress meter that is easy to adjust. Background Technology

[0002] The technical principle of stress gauges is mainly based on various mechanical principles, such as elastic deformation, resistance change, and optical measurement techniques. Specifically, stress gauges apply a certain load to the material under test, causing it to undergo elastic deformation, and then use sensors to measure the strain of the material.

[0003] Chinese utility model patent CN210719913U discloses a stress testing instrument, including a housing with a worktable fixedly connected to the top. A liftable platform, adjustable up and down, is located at the center of the worktable. A clamp is positioned above the liftable platform, and the clamp is slidably connected to the liftable platform via a sliding guide rail fixed above the liftable platform. A spotlight is located on one side of the liftable platform, and a support rod is located below the spotlight, fixedly connected to the worktable. Fixing plates are fixedly connected to both sides of the bottom of the spotlight. While this device achieves the goal of perfecting the placement of the test object by utilizing the liftable platform and the adjustable clamp, and allows for testing stress effects at different angles by adjusting the spotlight's emission angle, it is simple in structure, functionally complete, and highly practical. However, this device can only test the test object at a fixed angle or in a single direction, and cannot flexibly adjust the testing angle and direction according to actual needs. This limitation not only restricts the comprehensiveness of the test but may also lead to inaccurate test results.

[0004] Therefore, in order to address the shortcomings of the above-mentioned problems, a stress meter that is easy to adjust is proposed. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a stress meter that is easy to adjust.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a stress meter that is easy to adjust, comprising: a worktable, an adjustment mechanism disposed on the upper surface of the worktable, and a detector disposed on the upper surface of the worktable;

[0007] The bottom of the workbench is provided with a mounting groove, and a mounting plate is fixedly connected to the inner circumference of the mounting groove. A motor is fixedly connected to the upper surface of the mounting plate.

[0008] The adjustment mechanism includes: a lifting plate and a fixed ring, a rotating plate disposed on the upper surface of the lifting plate, a sliding unit disposed on the top of the rotating plate, and two symmetrical clamping plates disposed on the inner wall of the circumference of the fixed ring.

[0009] One end of the motor output shaft passes through the workbench and is fixedly connected to the bottom of the lifting plate, and the bottom of the rotating plate is rotatably connected to the upper surface of the lifting plate.

[0010] In a preferred embodiment of this utility model, the sliding unit is a fixed rod, which is fixedly connected to the outer circumference of the fixed ring. A slider is fixedly connected to the bottom of the fixed rod, and a groove is provided on the upper surface of the rotating plate.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] like Figure 1 As shown, an adjustable stress meter includes: a worktable 1, an adjustment mechanism 6 disposed on the upper surface of the worktable 1, and a detector 2 disposed on the upper surface of the worktable 1.

[0030] like Figures 2-3As shown, the bottom of the workbench 1 is provided with a mounting groove 8, the inner circumference of the mounting groove 8 is fixedly connected to a mounting plate 10, and the upper surface of the mounting plate 10 is fixedly connected to a motor 9.

[0031] The adjustment mechanism 6 includes: a lifting plate 601 and a fixed ring 606, a rotating plate 602 disposed on the upper surface of the lifting plate 601, a sliding unit disposed on the top of the rotating plate 602, and two symmetrical clamping plates 607 disposed on the inner circumference of the fixed ring 606; one end of the output shaft of the motor 9 passes through the worktable 1 and is fixedly connected to the bottom of the lifting plate 601, and the bottom of the rotating plate 602 is rotatably connected to the upper surface of the lifting plate 601;

[0032] The sliding unit is a fixed rod 605, which is fixedly connected to the outer circumference of the fixed ring 606. A slider 604 is fixedly connected to the bottom of the fixed rod 605. A groove 603 is provided on the upper surface of the rotating plate 602. The slider 604 is located in the groove 603 and is slidably connected. The outer circumference of the two clamping plates 607 is slidably connected to the inner circumference of the fixed ring 606. An adjusting screw 609 is rotatably connected to the outer circumference of both clamping plates 607. The adjusting screw 609 passes through the fixed ring 606 and is threaded. A clamping groove 608 is provided on the inner circumference of both clamping plates 607.

[0033] It should be noted that the lifting plate 601, driven by motor 9, can be adjusted vertically to ensure measurement of the object at different heights. Simultaneously, the fixing rod 605, slider 604, and groove 603 allow the fixing ring 606 and its clamping plate 607 to slide laterally on the rotating plate 602. This dual adjustment capability of height and lateral position allows the stress meter to adapt to objects of different sizes and shapes, improving testing accuracy and applicability. Furthermore, the two clamping plates 607 are slidably connected to the inner circumference of the fixing ring 606 and can be finely adjusted using the adjusting screw 609. This design not only allows the clamping plates 607 to closely conform to the shape of the object but also allows the user to adjust the clamping force and angle according to actual needs. The clamping groove 608 within the clamping plate 607 further enhances clamping stability, ensuring that the object does not move or deform during testing.

[0034] like Figures 1-2 As shown, a detector 2 is fixedly connected to the upper surface of the workbench 1. A first polarizer 3 is provided on one side of the detector 2. Two symmetrical fixing plates 5 are fixedly connected to the upper surface of the workbench 1. A slot 7 is provided on the opposite side of the two fixing plates 5. The same second polarizer 4 is engaged between the two slots 7.

[0035] It should be noted that the testing instrument 2 has the ability to directly perform stress testing on the test object. By fixing two symmetrical fixing plates 5 to the upper surface of the worktable 1 and opening a slot 7 on the opposite side, the second polarizer 4 can be clamped, so that the second polarizer 4 can be installed, removed and replaced separately. When the second polarizer 4 is damaged or needs to be upgraded, the user only needs to replace the new polarizer, without having to overhaul the entire stress instrument.

[0036] In use, the second polarizer 4 is aligned with the slots 7 on the two fixing plates 5 and inserted. To replace or remove the second polarizer 4, simply pull it out. The position and angle of the two clamping plates 607 are adjusted using the adjusting screw 609 according to the shape and size of the object to be tested. The adjusting screw 609 is rotated to allow the clamping plates 607 to slide within the fixing ring 606 until the clamping groove 608 tightly fits the object to be tested. The motor 9 is started, and the lifting plate 601 is used to adjust the vertical position of the object to be tested. The slider 604 on the sliding fixing rod 605 moves within the sliding groove 603 to adjust the horizontal position of the object to be tested. During testing, the detector 2 is started, and the object to be tested is placed between the clamping plates 607, ensuring it is aligned with the probe or measurement area of ​​the detector 2.

[0037] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
