Description

Technical Field

[0001] This utility model relates to the field of stress testing, specifically a stress meter device that is adjustable in multiple dimensions and is portable. Background Technology

[0002] The principle of stress detection technology relies on X-rays emitted from an X-ray tube, which irradiate the sample and are reflected onto a detector. The detector receives the signal, calculates the stress value at a specific point in the sample, and determines the stress value. Currently, several mainstream stress analyzers meet the needs of component testing. However, no existing stress analyzer can simultaneously meet the requirements of being compact, lightweight, and capable of comprehensive testing. This means that for certain components, such as the interior of small pipes, current stress analyzers are too large to access, or for complex, irregularly shaped gears requiring testing of all parts, current technology struggles to achieve the same results. Therefore, there is an urgent need for a compact stress analyzer that can flexibly perform comprehensive testing. Utility Model Content

[0030] Four rollers 103 are symmetrically mounted on the end face of the fixed base 101. The rollers 103 are fixed by roller fixing rods 102, and the V-shaped surface of the rollers 103 slides in cooperation with the V-shaped surface of the arc-shaped guide rail 104. A reducer 105 and a motor 106 are connected in sequence behind the fixed base 101. A gear 107 is mounted on the output shaft of the reducer 105, and the gear 107 meshes with the teeth on the arc-shaped guide rail 104.

[0031] An adjustment mechanism is provided below the reducer 105. The adjustment mechanism includes a left-right adjustment plate 108 and a right-down adjustment plate 109. The left-right adjustment plate 108 is slidably connected to the dovetail groove of the fixed base 101 via a dovetail groove. The right-down adjustment plate 109 is slidably connected to the dovetail groove of the left-right adjustment plate 108 via a dovetail groove. The lower end of the right-down adjustment plate 109 is fixed with a ray tube fixing plate 110.

[0032] A ray tube 111 is installed in the ray tube fixing plate 110. A detector fixing plate 112 is installed at the front end of the ray tube fixing plate 110. A detector 113 is installed on each of the left and right sides of the detector fixing plate 112. A collimating tube 114 is installed below the ray tube fixing plate 110. A focusing needle 115 is installed in the collimating tube 114.

[0033] The front end of the arc-shaped guide rail 104 is connected to the guide rail fixing plate 116. The concave groove above the guide rail fixing plate 116 is connected to the protruding end of the rotating block 117 by a rotating shaft 118, a pad 120, a pair of butterfly springs 121, and a nut 122. The rotating block 117 is connected to the connecting block 119 through the rotating shaft 118, the butterfly springs 121, and the nut 122.

[0034] The connecting block 119 is fixed on the support arm 2. The support arm 2 is connected to the tripod 4 through the connecting rod 3. The support arm 2 has a multi-section adjustable structure and supports 360-degree horizontal rotation and vertical lifting. The legs of the tripod 4 have a telescopic structure and are used to adjust the overall height of the device.

[0035] The adjustment mechanism drives the gear 107 to mesh with the arc-shaped guide rail 104 via the motor 106, causing the roller 103 to slide along the arc-shaped guide rail 104, so that the X-ray tube 111 and the detector 113 move around the center of the arc-shaped guide rail 104; the tip of the focusing needle 115 is aligned with the center of the arc-shaped guide rail 104 by adjusting the sliding position of the left and right adjustment plates 108 and the up and down adjustment plates 109.

[0036] The rotating block 117 and the guide rail fixing plate 116, as well as the rotating block 117 and the connecting block 119, can be stopped vertically or horizontally by the elastic force of the butterfly spring 121, and the stopping angle can be manually adjusted and locked.

[0037] The support arm 2 is a multi-section adjustable structure, with each section connected by hinges or slide rails, supporting the stress meter assembly 1 to rise and fall vertically and rotate 360 ​​degrees horizontally.

[0038] The tip of the focusing needle 115 coincides with the center of the arc-shaped guide rail 104.

[0039] The working principle of this utility model is as follows: The tripod 4 is unfolded, and the extension length of the legs is adjusted to adapt to the height of the detection environment. The stress meter assembly 1 is moved to the vicinity of the area to be measured via the multi-section adjustable structure of the support arm 2. The rotation angle between the rotating block 117 and the connecting block 119 is manually adjusted to place the stress meter assembly 1 in the optimal detection position. The left-right adjustment plate 108 and the up-down adjustment plate 109 are operated to slide along the dovetail groove to adjust the position of the X-ray tube fixing plate 110, ensuring that the tip of the focusing needle 115 is precisely aligned with the center of the arc-shaped guide rail 104, thus ensuring the focusing accuracy of the X-ray beam and the detector 113. The motor 106 is started, driving the gear 107 to rotate via the reducer 105. The gear 107 meshes with the teeth on the arc-shaped guide rail 104, causing the roller 103 to slide along the V-shaped surface of the arc-shaped guide rail 104. This allows the X-ray tube 111 and the detector 113 to move in an arc around the center of the guide rail, covering different detection angles. During this movement, at point A on the surface of the object being measured (e.g., Figure 10 X-ray tube 111 continuously emits X-rays, and detector 113 receives the reflected signals and transmits them to an external processing system in real time. The stress distribution is calculated by analyzing the diffraction angle shift. If the detection range needs to be adjusted, motor 106 can be paused, rotating block 117 can be manually stopped, or the angle of support arm 2 can be adjusted. After repositioning, the detection can continue.
