Technical Field

[0001] This utility model belongs to the field of magnetic stress detection technology, and in particular relates to a probe assembly suitable for magnetic stress detection devices. 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 probe assembly suitable for magnetic stress measurement devices, making it more industrially valuable. Utility Model Content

Several induction columns are connected circumferentially along the fixed base, with equal intervals between them. Coils are connected to both the induction columns and the excitation columns. A sliding groove is formed radially on the fixed base, and several positioning grooves are formed on the inner wall of the sliding groove, with equal intervals between them. The number of sliding grooves is the same as the number of induction columns. A slider is slidably connected within the sliding groove, and a connecting plate is connected to the slider. Induction columns are connected to the connecting plate. A positioning groove is formed on the side of the slider, and a positioning post that mates with the positioning groove is connected within the positioning groove. A connecting piece is connected to the positioning post. A compression spring is connected within the positioning groove, with one end of the compression spring contacting the bottom of the positioning groove and the other end contacting the positioning post.

[0008] Preferably, in the probe assembly suitable for a magnetic stress measuring device, the positioning grooves are formed on the two side walls of the slide groove, and they are arranged opposite to each other.

[0009] Preferably, in the probe assembly suitable for a magnetic stress measuring device, the slider has positioning grooves on both the left and right sides, with the positioning grooves being positioned opposite to the positioning recesses.

[0010] Preferably, in the probe assembly suitable for a magnetic stress measuring device, the connecting plate and the slider are provided with opposing guide grooves, and the connecting piece slides on the guide grooves.

[0021] Example

[0022] like Figure 1 and Figure 2 As shown, a probe assembly suitable for a magnetic stress measuring device 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 circumferentially along the fixed base, and the induction columns 3 are spaced equidistantly. A coil 4 is connected to both the induction columns 3 and the excitation columns 2. A groove 5 is formed radially on the fixed base 1, and several positioning grooves 8 are formed on the inner wall of the groove 5, spaced equidistantly. The number of sliding grooves 5 is the same as the number of sensing columns 3. A slider 6 is slidably connected in the sliding groove 5. A connecting plate 7 is connected to the slider 6. A sensing column 3 is connected to the connecting plate 7. A positioning groove 9 is opened on the side of the slider 6. A positioning post 10 that cooperates with the positioning groove 8 is connected in the positioning groove 9. A connecting piece 11 is connected to the positioning post 10. A compression spring 12 is connected in the positioning groove 9. One end of the compression spring 12 contacts the bottom of the positioning groove, and the other end contacts the positioning post 10.

[0023] In this invention, the positioning grooves 8 are formed on both sides of the slide groove and are arranged opposite to each other. Simultaneously, positioning slots 9 are formed on both the left and right sides of the slider 6, and are arranged opposite to the positioning grooves 8. The cooperation of the positioning slots on both sides of the slide groove and the slider ensures that the slider is stably and firmly connected to the fixed base.

[0024] In this invention, the connecting plate 7 and the slider 6 are provided with opposing guide grooves 13. The connecting piece 11 slides on the guide groove, and a connecting block 14 is connected to the connecting piece 11. The connecting plate 7 is provided with a guide groove 15 for the sliding of the connecting block. With the above structure, pressing the connecting block can retract the positioning post, thereby disengaging the positioning post from the positioning groove. Then, the slider is moved to the designated position, and the connecting block is released. The positioning post rebounds through the spring and extends into the positioning groove.

[0025] The working principle of this utility model is as follows:

[0026] In actual operation, when it is necessary to change the position of the sensing column, the positioning column can be retracted by pressing the connecting block, so that the positioning column is disengaged from the positioning groove. Then, the slider is moved to the designated position, and the connecting block is released. The positioning column rebounds through the spring and extends into the positioning groove. At this time, it is fixed in the positioning groove by the positioning columns on both sides, ensuring the stability of the slider and the sensing column.

[0027] The working principle of this utility model has been disclosed (publication number: CN210346952U), and will not be described in any further detail.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.
