[0002] In fields such as machinery manufacturing, petrochemicals, aerospace, construction engineering, railways and highways, and water conservancy and hydropower, the stress state and microstructure of materials are the main factors affecting their service life. Non-destructive testing of residual stress and certain mechanical properties of structures has significant economic and practical value.
[0003] Magnetic stress measurement assesses internal stress based on the change in magnetism of ferromagnetic materials under stress. A magnetic stress meter is typically used to detect internal stress. During operation, the probe and the object are usually used together for testing. For three-stage probes, testing is usually required after production and processing. Traditionally, this is done manually, with operators visually inspecting the material. This method demands highly skilled workers, has low accuracy, increases labor costs, and is inefficient, failing to meet the demands of modern high-speed production.

[0020] Example
[0021] like Figure 1 and Figure 2 As shown, a testing fixture for a three-stage probe of a magnetic stress measuring instrument includes a fixed base 1. The fixed base 1 has three working areas 2, each with a placement groove 3. A contour positioning block 4 is connected to one side of each placement groove 3, and a sliding groove 5 is provided on the other side of the placement groove 3. A sliding fixing block 6 is slidably connected to the sliding groove 5. A transmission hole 7 is provided at the bottom of the fixed base 1, and a transmission rod 8 passes through the transmission hole 7. A synchronous connecting rod 9 is connected to the transmission rod 8. 9 passes through the slide groove and is connected to the sliding fixing block 6. The end of the fixing base 1 is connected to the drive device 10 connected to the transmission rod 8. The fixing base 1 is connected to the slide rail 11. The slide rail 11 is connected to the fixing plate 12 through the slider. The fixing plate 12 is connected to the support rod 13. The top of the support rod 13 is connected to the detection fixing plate 14. The detection fixing plate 14 is connected to the detection cylinder 15. The drive shaft of the detection cylinder 15 is connected to the detection connecting plate 16. The detection connecting plate 16 is connected to the detection block 17.
[0022] In this utility model, a fixed base 1 is connected to a bearing with a seat, a lead screw is connected between the bearings with seats, a sliding block is connected to the lead screw, the sliding block is connected to the fixed plate through a connecting block, and a drive motor that drives the lead screw is connected to the fixed base 1.
[0023] In this invention, a sensor is connected to the fixed base 1 located at the placement groove, and a sensing element for sensing the sensor is connected to the fixed plate 12. The sensor is a proximity switch.
[0024] In this utility model, the driving device 10 is a cylinder.
[0025] The working principle of this utility model is as follows:
[0026] During specific operation, the products are sequentially placed in the corresponding placement grooves and positioned by the profiling positioning blocks. Then, a driving device (cylinder) pulls the transmission rod to move the sliding fixing block towards the profiling positioning block, so that the products are fixed by the profiling positioning blocks and the sliding fixing block. Finally, the detection block detects the fixed products. If the detection block can perfectly match the products, it indicates that the products are qualified; otherwise, the products are unqualified. After completing the first detection, the detection block is moved to the next working area through the screw drive device, and the proximity switch is used to ensure the position of the products, so that the detection block stops at the specified position to ensure accurate detection of the products for the second and / or third time.
[0027] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application. In addition, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.
[0029] In addition, the terms "horizontal", "vertical", etc. do not mean that the components are required to be absolutely horizontal or vertical, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.
[0030] In the description of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "install", "connect", "couple" should be understood in a broad sense.
