Specific implementation manners
[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Refer to Figures 1-3, an embodiment provided by the present utility model: a magnetic roller displacement measuring device, including a mounting plate 1, on which an adjusting mechanism 4 is provided. By setting the adjusting mechanism 4, the magnetic roller can be adjusted to fit different concave and convex surfaces for strain adjustment. An auxiliary mechanism 5 is provided on the adjusting mechanism 4. By setting the auxiliary mechanism 5, the brush holder 49 can be disassembled and adjusted. The adjusting mechanism 4 includes an adjusting frame 41, which is fixedly connected to the top outer wall of the mounting plate 1. A rotary encoder main body 42 is slidably connected to the inner walls on both sides of the adjusting frame 41. By setting the rotary encoder main body 42 to cooperate with the magnetic roller main body 47, the displacement during the movement of the object is measured. Since the above mechanisms are prior art, no more detailed description will be given here. A threaded groove 43 is opened on the top inner wall of the adjusting frame 41, and a threaded disk 44 is threadedly connected to the side inner wall of the threaded groove 43. A spring damper 45 is fixedly connected to the bottom outer wall of the threaded disk 44. By setting the spring damper 45, when the magnetic roller main body 47 contacts objects of different heights, it can perform telescopic strain adjustment. The output end of the rotary encoder main body 42 is fixedly connected to the magnetic roller main body 47 through a coupling. An installation frame 48 is fixedly connected to the outer wall on one side of the rotary encoder main body 42, and a brush holder 49 is clamped to the inner wall on one side of the installation frame 48.
[0025] Referring to Figures 2-3 , an indication mark is opened on the side outer wall of the threaded disk 44. One end of the spring damper 45 away from the threaded disk 44 is clamped to the top outer wall of the rotary encoder main body 42. The magnetic roller main body 47 is rotatably connected to the outer wall on one side of the rotary encoder main body 42 through a bearing. The brush holder 49 is slidably connected to the outer wall on the side of the magnetic roller main body 47. The width of the brush holder 49 is adapted to the width of the magnetic roller main body 47. By setting the brush holder 49, the outer surface of the magnetic roller main body 47 and the surface of the measuring object when contacting the magnetic roller main body 47 are wiped to a certain extent to avoid measurement accuracy errors caused by dirt. A frame 2 is fixedly connected to the bottom outer wall of the mounting plate 1, and an operation platform 3 is fixedly connected to the outer wall on one side of the frame 2 away from the mounting plate 1.
[0026] Referring to Figures 3-4 , the auxiliary mechanism 5 includes a sliding plate 51, which is slidably connected to the inner wall on one side of the brush holder 49. A small spring 52 is fixedly connected to the outer wall on one side of the sliding plate 51. An arc-shaped block 54 is fixedly connected to the outer wall on the side of the sliding plate 51 away from the small spring 52. By setting the arc-shaped block 54, the brush holder 49 can be separated from and assembled with the installation frame 48. An installation opening 55 is opened on the inner wall on one side of the installation frame 48. One end of the small spring 52 away from the sliding plate 51 is fixedly connected to the inner wall on one side of the brush holder 49. By setting the small spring 52, a continuous thrust is generated on the sliding plate 51. The arc-shaped block 54 penetrates through the outer wall on one side of the brush holder 49, and an annular groove 53 is opened on the top outer wall of the brush holder 49. The arc-shaped block 54 is clamped to the inner walls on both sides of the installation opening 55.
[0027] Working principle: When the magnetic roller body 47 is about to contact the measured object, the surface of the measured object is wiped and cleaned through the brush holder 49. Subsequently, the measured object contacts the magnetic roller body 47 for testing. At the same time, the brush holder 49 wipes the surface of the rolling magnetic roller body 47 to reduce the influence of external dust and dirt on the measurement accuracy of the device. When measuring a relatively high object, the magnetic roller body 47 moves upward to drive the rotation encoder body 42 to move. The rotation encoder body 42 moves to squeeze the spring damper 45 for telescopic adjustment. At the same time, after long-term use, the threaded disk 44 is rotated to separate from the threaded groove 43, and the rotation encoder body 42 is disassembled and assembled for convenient debugging and assembly. At the same time, by pulling the sliding plate 51 to squeeze the small spring 52, the sliding plate 51 moves to drive the arc-shaped block 54 to move. The arc-shaped block 54 moves to separate from the mounting opening 55. Subsequently, the brush holder 49 is pulled out and separated from the mounting frame 48 for maintenance and cleaning.
[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
