Description

Technical Field

[0001] This utility model belongs to the field of magnetic stress detection technology, and in particular relates to a probe for magnetic stress measurement. Background Technology

[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. Magnetic testing assesses internal stress based on the change in magnetism of ferromagnetic materials under stress.

[0003] Traditional probes typically need to be replaced according to the size of the object being measured during use. Different sizes of objects require different probe specifications. Therefore, magnetic stress measuring instruments often need to change probes before use, which takes a lot of time and results in low testing efficiency.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a new type of magnetic stress measurement probe with a more industrial application value. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a probe for magnetic stress measurement.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A magnetic stress measuring probe includes a fixed base, which is circular in structure. An excitation column is connected to the center of the fixed base. Several induction columns are connected circumferentially along the fixed base, with equidistant spacing between them. Coils are connected to both the induction columns and the excitation columns. A slide rail groove is formed radially on the fixed base, the number of which is the same as the number of induction columns. A slider is connected within the slide rail groove, and the induction columns are connected to the slider. A guide groove communicating with the slide rail groove is formed on the back of the fixed base. A guide block is connected within the guide groove, and the guide block is connected to the slider via a synchronous connecting block. A synchronous guide rod is connected to the guide block. A synchronous pushing assembly connected to the synchronous guide rod is connected to the center of the back of the fixed base. A synchronous spring is connected within the slide rail groove, one end of which contacts the slider, and the other end contacts the fixed block.

[0008] Preferably, in the magnetic stress measuring probe, the fixing block is snapped onto the slide rail groove, and the fixing block is also connected to the end of the fixing base.

[0009] Preferably, in the magnetic stress measuring probe, the fixing block has a mounting groove for a synchronization spring.

[0010] Preferably, in the magnetic stress measuring probe, the synchronous pushing assembly includes a synchronous pushing block, which is in the form of a ring. A guide hole is provided on the side of the synchronous pushing block, and a synchronous guide rod passes through the guide hole. A pushing block is connected in the circular hole of the synchronous pushing block, and the side of the pushing block contacts the synchronous guide rod. A pushing spring is connected to the back of the fixed base, and the pushing spring contacts the end of the pushing block.

[0011] Preferably, in the magnetic stress measurement probe, the pushing block has a conical structure.

[0012] Preferably, in the magnetic stress measuring probe, the pushing block is screwed to the synchronous pushing block.

[0013] By means of the above solution, this utility model has at least the following advantages:

[0021] Example

[0022] like Figure 1 and Figure 2 As shown, a magnetic stress measurement probe includes a fixed base 1, which is circular in structure. An excitation column 2 is connected to the center of the fixed base 1. Several induction columns 3 are connected along the circumference of the circular fixed base 1, and the induction columns 3 are arranged at equal intervals. A coil 12 is connected to both the induction columns 3 and the excitation columns 2. A slide rail groove 4 is formed in the radial direction of the fixed base 1, and the number of slide rail grooves 4 is the same as the number of induction columns 3. A coil 12 is connected within each slide rail groove 4. The slider 5 is connected to the sensing column 3. The back of the fixed base 1 is provided with a guide groove 6 that communicates with the slide rail groove. A guide block 7 is connected in the guide groove 6. The guide block 7 is connected to the slider 5 through a synchronous connecting block. A synchronous guide rod 8 is connected to the guide block 7. A synchronous pushing component 9 connected to the synchronous guide rod is connected at the center of the back of the fixed base 1. A synchronous spring 10 is connected in the slide rail groove 4. One end of the synchronous spring 10 contacts the slider 5, and the other end contacts the fixed block 11.

[0023] The fixing block 11 described in this utility model is snapped onto the slide rail groove 4, and the fixing block 11 is also connected to the end of the fixing base 1.

[0024] The fixing block 11 of this utility model has a mounting groove for the synchronization spring, which facilitates the fixing and installation of the synchronization spring.

[0025] The synchronous pushing component 9 of this utility model includes a synchronous pushing block 91, which has a circular ring structure. A guide hole 92 is provided on the side of the synchronous pushing block 91, and the synchronous guide rod 8 passes through the guide hole. A pushing block 93 is connected in the circular hole of the synchronous pushing block 91, and the side of the pushing block 93 contacts the synchronous guide rod 8. A pushing spring 94 is connected to the back of the fixed base 1, and the pushing spring 94 contacts the end of the pushing block 93. The pushing block 93 has a conical structure and is screwed to the synchronous pushing block 91.

[0026] The aforementioned synchronous pushing component enables the pushing of each slider, achieving synchronization and ensuring the accuracy of detection.

[0027] The working principle of this utility model is as follows:

[0028] In actual operation, the synchronous guide rod is pushed by rotating the push block in the synchronous push component. After the synchronous guide rod is pushed, the guide block connected to it is pushed. After the guide block is pushed, the slider connected to it synchronously is also pushed, so that all the sliders on the fixed base move together in the same direction. The movement of the slider will drive the synchronous movement of the sensing column, thereby achieving fast, efficient and precise movement.

[0029] The working principle of this utility model has been disclosed (publication number: CN210346952U), and will not be described in any further detail.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] In the description of this application, it should be noted that the terms "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0033] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
