[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 As shown;

[0025] A height-adjustable surface roughness comparison sample block detection device comprises an upper box body 1.

[0026] In this embodiment: After checking the public (announcement) number: CN219301582U discloses a height-adjustable surface roughness comparison sample block detection device. Although the design has higher lifting efficiency and is more stable, the box adopts a split design, and the rise and fall are more stable. However, when the staff compares the roughness of the tested workpiece, they usually need to hold a magnifying glass 28 for comparison. Long-term work will cause arm soreness and reduce work efficiency. In addition, the detection device needs to put the tested workpiece into the detection slot. If a smaller workpiece is encountered, it will be difficult to take the tested workpiece out of the detection slot. In order to solve this technical problem, a detection component 2 is added on this basis.

[0027] More specifically:

[0028] like Figures 1 to 4 As shown:

[0029] In combination with the above content: the detection component 2 includes a detection box 21, a sliding groove 22, a support plate 23 and a power-assisting handle 24. The upper surface of the upper box body 1 is fixedly connected with the detection box 21. Two sliding grooves 22 are provided on both sides of the detection box 21. A support plate 23 is arranged inside the detection box 21. Two power-assisting handles 24 pass through the sliding groove 22 and are fixedly connected to both sides of the support plate 23. Four detection platforms 25 are fixedly connected to the upper surface of the support plate 23. A through hole matching the detection platform 25 is provided on the outer side of the top end of the upper box body 1.

[0030] In this embodiment: when it is necessary to use the device to perform roughness detection on the workpiece, first lift the support plate 23 through the two power-assisting handles 24, then place the workpiece to be detected and the sample on the surface of the detection table 25 respectively, and then lower the support plate 23, and detect its roughness by observation. After the detection is completed, it is only necessary to lift the support plate 23 upward again, expose the workpiece on the surface of the detection table 25 to the upper surface of the upper box body 1, and then take the workpiece away, which is convenient for taking and placing the workpiece and improves the detection efficiency.

[0031] Going further:

[0032] In an optional embodiment, a sleeve 26 is fixedly connected to the interior of a through hole provided at the top of the detection box 21 .

[0033] In this embodiment, in order to further ensure the stability of the support plate 23 when it rises, the table sleeve 26 inside the upper box body 1 is sleeved on the surface of the detection table 25 to ensure that the support plate 23 will not tilt to both sides when moving upward, thereby improving the stability of the device.

[0034] It should be noted that the table sleeve 26 is a cylindrical structure. When the support plate 23 is located at the lowest end inside the upper box body 1, the test table 25 will not fall out of the table sleeve 26, ensuring that the support plate 23 does not need to align the test table 25 and the table sleeve 26 when moving upward.

[0035] Going further:

[0036] In an optional embodiment, a rotating block 27 is disposed on the upper surface of the detection box 21 , and ends of the rotating block 27 are respectively fixedly connected with a magnifying glass 28 and a plane mirror 29 .

[0037] In this embodiment: a rotating block 27 is provided on the upper surface of the upper box body 1, and the workpiece can be magnified and inspected through the magnifying glass 28 at the end of the rotating block 27. If the workpiece does not need to be magnified, a plane mirror 29 can be used to inspect it. The rotating block 27 can rotate, and the workpieces on the surface of each inspection table 25 can continue to be observed. At the same time, the workpiece can be protected from direct contact with the external environment and some contaminants can be prevented from falling onto the surface of the workpiece, which is convenient for the staff to inspect the workpiece while protecting the workpiece to be inspected.

[0038] It should be noted that the rotating block 27 is a simple rotatable structure with a rotating shaft in the middle, and four connecting rods are fixedly connected to the surface of the rotating shaft. The ends of the four connecting rods are respectively fixedly connected to a magnifying glass 28 and a plane mirror 29. The magnifying glass 28 has a lens with magnifying power, and the plane mirror 29 is a plane lens.

[0039] Going further:

[0040] In an optional embodiment, a suction cup 210 is fixedly connected to the lower surface of the rotating block 27 , and the rotating block 27 is detachably connected to the upper box body 1 via the suction cup 210 .

[0041] In the present embodiment: in order to facilitate the disassembly of the rotating block 27, a suction cup 210 is fixedly connected to the lower surface of the rotating block 27, and the rotating block 27 can be detachably connected to the upper box body 1 through the suction cup 210. When the inspection of the workpiece is completed, the rotating block 27 can be disassembled through the suction cup 210, and then the inspected workpiece can be recovered by lifting the pallet 23.

[0042] Going further:

[0043] In an optional embodiment, an annular light source 211 is installed on the lower surface of the magnifying mirror 28 and the plane mirror 29 .

[0044] In this embodiment, in order to make the illumination more uniform, an annular light source 211 is provided on the lower surface of the magnifying glass 28 and the plane mirror 29. Compared with different light sources, the light emitted by the annular light source 211 is more uniform, thereby ensuring the rigor of the detection and improving the credibility of the detection results.

[0045] Going further:

[0046] In an optional embodiment, a lower box body 212 is disposed inside the detection box 21 , a lifting rod 213 is installed on the upper surface of the lower box body 212 , and an end of the lifting rod 213 is fixedly connected to the inner surface of the upper box body 1 .

[0047] In this embodiment: the upper box body 1 can be raised and lowered by the lifting rod 213 on the upper surface of the lower box body 212, thereby improving the flexibility of the device.

[0048] It should be noted that the lower box body 212 is inside the upper box body 1 and is slidably connected to the upper box body 1 .

[0049] Working principle: When the device needs to be used to detect the roughness of the workpiece, first lift the support plate 23 through the two power-assisting handles 24, then place the workpiece to be detected and the sample on the surface of the detection table 25 respectively, and then lower the support plate 23 to detect its roughness by observation. After the detection is completed, it is only necessary to lift the support plate 23 upward again, expose the workpiece on the surface of the detection table 25 to the upper surface of the upper box body 1, and then take the workpiece away, which is convenient for taking and placing the workpiece and improves the detection efficiency. In order to further ensure the stability of the support plate 23 when it rises, the table sleeve 26 inside the upper box body 1 is sleeved on the surface of the detection table 25 to ensure that the support plate 23 will not tilt to both sides when moving upward, thereby improving the stability of the device. A rotating block 27 is provided on the upper surface of the upper box body 1, and the workpiece can be magnified and detected by the magnifying glass 28 at the end of the rotating block 27. If the workpiece does not need to be magnified, it can be detected by using a plane mirror 29, and the rotating block 27 can be rotated. In order to continue to observe the workpieces on the surface of each inspection table 25, it can also protect the workpieces from direct contact with the external environment and prevent some pollutants from falling onto the surface of the workpieces, so that the staff can detect the workpieces while protecting the workpieces to be inspected. In order to facilitate the disassembly of the rotating block 27, a suction cup 210 is fixedly connected to the lower surface of the rotating block 27, and the rotating block 27 can be detachably connected to the upper box body 1 through the suction cup 210. When the inspected workpiece is inspected, the rotating block 27 can be disassembled through the suction cup 210, and then the inspected workpiece can be recovered by lifting the pallet 23. In order to make the illumination more uniform, an annular light source 211 is arranged on the lower surface of the magnifying glass 28 and the plane mirror 29. Compared with different light sources, the light source emitted by the annular light source 211 is more uniform, which ensures the rigor of the inspection and improves the credibility of the inspection results. In addition, the upper box body 1 can be lifted and lowered by the lifting rod 213 on the upper surface of the lower box body 212, thereby improving the flexibility of the device.
