Description

Technical Field

[0001] This utility model relates to the field of testing mechanism technology, and in particular to a static magnetic grating angle testing device. Background Technology

[0002] The static magnetic grating position detection mechanism is a high-precision and high-reliability position detection device. Through its unique structure and working principle, it can accurately detect the displacement of the measuring rod and is widely used in occasions that require high-precision position detection.

[0003] A search revealed a static magnetic grating position detection mechanism with publication number CN222505287U, belonging to the technical field of detection mechanisms. It includes a second workbench and a detection mechanism body. A fixed plate is fixedly connected to the top of the second workbench, and a cylinder is fixedly connected to one side of the fixed plate. A connecting rod is fixedly connected to the output shaft of the cylinder, and a rack is fixedly connected to one end of the connecting rod. A sliding groove is fixedly connected to the top of the second workbench. This invention adds a rotating mechanism to the static magnetic grating position detection mechanism, allowing it to cover a wider area or angle, thus achieving omnidirectional detection of object displacement or angle. Furthermore, by adding a rotating mechanism to the detection mechanism body, the detection range is expanded. This design allows for position detection in multiple directions or angles, improving the comprehensiveness and accuracy of the detection.

[0004] The above patent also has the following shortcomings: after using the moving wheel to move the device, the stability of the entire device is insufficient due to the support of the moving wheel alone for subsequent testing. The contact area with the ground is small, making the device easy to move or tip over under external force, causing damage. In addition, it is not convenient to disassemble and assemble the main body of the testing mechanism, and it is inconvenient to remove it for repair or replacement, which affects subsequent use. Therefore, the device has certain shortcomings. Utility Model Content

[0032] The fixing assembly includes an electric telescopic rod 21. A sliding groove 19 and a slot 20 are provided in the fixing plate 18. The electric telescopic rod 21 is fixedly connected to the slot 20 by bolts. A movable seat 22 is fixedly connected to the output end of the electric telescopic rod 21. A drive plate 23 is rotatably connected to the side of the movable seat 22. Two sets of drive plates 23 are symmetrically arranged. A slider 25 is rotatably connected to one end of the drive plate 23. A guide plate 24 is fixedly connected to the slot 20. The slider 25 slides outside the guide plate 24 and slides within the sliding groove 19. A clamping plate 26 is fixedly connected to the side of the slider 25. The adjusting assembly includes a first drive motor 14. The first drive motor 14 is fixedly connected to the top of the support base 1 by bolts. An electromagnetic brake is installed on the output shaft of the first drive motor 14. A support plate 15 is fixedly connected to the output end of a drive motor 14. A fixing block 16 is fixedly connected to the top of the support plate 15. A second drive motor 17 is fixedly connected to the top of the fixing block 16 by bolts. An electromagnetic brake is installed on the output shaft of the second drive motor 17. The output end of the second drive motor 17 is fixedly connected to the fixing plate 18. The limiting assembly includes a slide rod 8. A circular groove 7 is opened in the top plate 28. The slide rod 8 slides in the circular groove 7.

The connecting plate 12 is parallel to the bottom of the support base 1 to facilitate the smooth movement of the universal wheel 13 with brake.

[0033] Working principle: In the static magnetic grating angle detection device, pulling down the baffle 9 causes the top of the slide rod 8 to slide out of the limiting hole 6, stretching the spring 10. Rotating the fixed plate 5 causes the threaded rod 4 to rotate, and the threaded rod 4 causes the moving plate 11 to slide along the fixed rod 3. Releasing the baffle 9 allows the slide rod 8 to slide upward into a set of limiting holes 6 corresponding to the circular groove 7 under the action of the spring 10, thus fixing the position of the fixed plate 5. This facilitates the adjustment of the height of the universal wheel 13 with brake. When the device needs to be moved, the universal wheel 13 with brake is lowered and moved. When no movement is needed and detection is required, the universal wheel 13 with brake is raised to support the base. 1. The bottom is grounded, increasing the grounding area and device safety, and enhancing detection stability; activating the electric telescopic rod 21 drives the moving seat 22 to move, which in turn drives the drive plate 23 to rotate, thereby causing the sliders 25 on both sides to slide in opposite directions on the outside of the guide plate 24. This allows the clamping plates 26 on both sides to fix or release the detection structure body 27, facilitating easy assembly and disassembly of the detection structure body 27 for maintenance or replacement without affecting subsequent detection use; activating the first drive motor 14 or the second drive motor 17 can adjust the detection angle of the detection structure body 27 for a more comprehensive inspection.
