Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-4 An embodiment of this utility model is provided: a measuring rod for a static magnetic grating linear displacement sensor, including a measuring rod body 1 and a support frame 2. The measuring rod body 1 is externally connected to a protective component 7 that improves reliability. The top of the support frame 2 is connected to a guide component 3 that improves measurement accuracy and repeatability. The top of the guide component 3 is connected to a limiting component 10 that improves stability.

[0030] The guide assembly 3 includes a fixing frame 4, the bottom of which is fixedly connected to the top of the support frame 2. A guide groove 5 is provided on the inner side of the fixing frame 4, and a guide plate 6 is slidably connected inside the guide groove 5. The inner side of the guide plate 6 is fixedly connected to the outer side of the protective assembly 7.

[0031] The protective assembly 7 includes a protective shell 8, the outer side of which is fixedly connected to the inner side of the guide plate 6. Sealing rings 9 are fixedly fitted at both ends of the inner side of the protective shell 8 to prevent external dust and moisture from entering. The sealing rings 9 are fixedly fitted onto the outside of the measuring rod body 1, which is located inside the protective shell 8. The limiting assembly 10 includes a threaded rod 11, which is threadedly connected to the top of the fixing frame 4. A handle 12 is fixedly connected to one end of the threaded rod 11, and a limiting block 13 is rotatably connected to the other end. A connector 14 is fixedly connected to one end of the measuring rod body 1, and a connecting plate 15 is fixedly connected to one end of the connector 14. A static magnetic grid sensor 16 is fixedly installed on one end of the connecting plate 15 by bolts. A mounting plate 17 is fixedly connected to the bottom of the support frame 2, and mounting holes 18 are provided inside the mounting plate 17. The limiting block 13 is made of rubber to increase friction and improve stability. The protective shell 8 is made of stainless steel, which has high strength, corrosion resistance, oxidation resistance, and good electromagnetic shielding performance.

[0032] Working principle: First, the support frame 2 is fixedly installed in the required position with bolts to provide stable support for the whole. When the measuring rod body 1 needs to move, the guide plate 6 slides in the guide groove 5 of the fixed frame 4 to ensure that the measuring rod body 1 moves smoothly along a straight line, reducing measurement errors caused by shaking and improving measurement accuracy and repeatability. The protective shell 8 is made of stainless steel, which provides physical and chemical protection for the measuring rod body 1 and resists electromagnetic interference. The sealing rings 9 at both ends are tightly fitted on the outside of the measuring rod body 1 to further prevent dust and moisture from entering the interior of the protective shell 8, ensuring that the measuring rod body 1 is in a good working environment and improving reliability. When the measuring rod body 1 moves to the designated position, the throttle 12 is turned to drive the threaded rod 11 to rotate, so that the threaded rod 11 pushes the limit block 13 to move down, fixing the position of the measuring rod body 1 and preventing it from being displaced by external forces, thus enhancing stability. At this time, the static magnetic grating sensor 16 is linked with the measuring rod body 1 through the connecting plate 15 and the connector 14. Based on the static magnetic grating principle, it accurately measures the displacement and outputs the corresponding signal to achieve accurate displacement measurement.
