Description

Technical Field

[0001] This utility model relates to a surface roughness detection device, specifically a rotatable box-type rapid surface roughness detection device. Background Technology

[0002] In modern manufacturing, surface strengthening technology plays a crucial role. Through special treatments such as shot peening and laser strengthening, it enhances the wear resistance, fatigue strength, and corrosion resistance of parts, thereby extending their service life and optimizing product quality. In this process, surface roughness becomes one of the core factors affecting the strengthening effect, directly impacting the quality of the strengthened layer and the final performance of the part. However, in actual production, the surface roughness of parts often varies due to factors such as processing errors, material fluctuations, or environmental variables. Therefore, surface roughness testing is necessary after surface strengthening treatment.

[0003] Traditional inspection methods rely on workers visually assessing the surface roughness of parts, resulting in low efficiency and accuracy. To address this, researchers have developed various surface roughness inspection devices with different structures. For example, patent CN212458241U discloses a surface roughness measuring device, and patent CN222258170U discloses a height-adjustable surface roughness comparison sample inspection device. These devices improve the efficiency and accuracy of surface roughness inspection, but they also suffer from relatively complex structures, large sizes, and limited application scenarios. Utility Model Content

[0004] The purpose of this invention is to solve the technical problems of existing surface roughness detection devices, such as relatively complex structure, large size, and limited application scenarios, and to provide a rotatable box-type rapid surface roughness detection device.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A rotatable box-type rapid surface roughness inspection device, characterized by:

[0007] Includes the outer casing, rotating sample placement assembly, and light source;

[0008] The outer shell has a hollow structure; a central rod is provided inside the outer shell, which coincides with the central axis of the outer shell, and its two ends are respectively connected to the upper and lower bottom surfaces of the outer shell; the upper bottom surface of the outer shell has an annular groove that is coaxial with the outer shell and communicates with the hollow structure.

[0009] The rotating sample placement assembly is located within a cavity structure and includes a base, multiple sample placement stages or multiple sample placement stages and a protective partition, and a rotating handle. The base is coaxially arranged with the central rod and sleeved on the outside of the central rod, allowing it to rotate around the central rod. The multiple sample placement stages, or multiple sample placement stages and a protective partition, are evenly distributed around the circumference of the base and are connected to the base via connecting rods. Each sample placement stage is used to place standard sample blocks with different surface roughnesses. The thickness of the protective partition is greater than the thickness of the sample placement stage. One end of the rotating handle is mounted on one of the connecting rods, and the other end extends out of the outer shell through an annular groove.

[0010] The upper bottom surface of the outer shell is provided with an observation window, the position of which corresponds to the position of the sample stage in the circumferential direction within the cavity structure; there are two light sources, one of which is installed on the upper bottom surface of the outer shell near the observation window to illuminate the standard sample block, and the other light source is used to hand-illuminate the product to be tested.

[0011] Furthermore, the distance between the observation window and the sample placement stage and the central rod is consistent, and their shapes and sizes are compatible.

[0012] Furthermore, a fixed platform is provided on the upper surface of the outer shell near the observation window, and a light source is installed on the fixed platform. The light-emitting surface of the light source is 1-4 mm higher than the upper surface of the standard sample block, and the optical axis forms an angle of 10-20° with the upper surface of the standard sample block.

[0013] Furthermore, the light source is selected as a green light source with a wavelength of 500-600nm.

[0014] Furthermore, the light source is selected as a green light source with a wavelength of 555nm.

[0015] Furthermore, there are five sample placement stages, and each sample placement stage is a rectangular platform with a groove on the upper surface of the rectangular platform, into which the standard sample block is placed.

[0016] Furthermore, the thickness of the sample placement stage is 4–6 mm.

[0017] Furthermore, the end of the rotary handle extending out of the housing is provided with a handle.

[0018] The advantages of this utility model compared to the prior art are:

[0019] 1. This utility model provides a rotatable box-type rapid surface roughness detection device with a simple and compact overall structure. By rotating the handle, the sample stage can be rotated, thereby rotating the standard sample with the corresponding surface roughness to the observation window. By comparing and observing the surface morphology of the standard sample and the product under the light source, it can be determined whether the surface roughness of the product under the test meets the requirements. This device is applicable to the rapid detection of products with different surface roughness.

[0020] 2. This utility model also provides a protective barrier. When the rapid testing device is not in use, the protective barrier can be rotated to the observation window position to prevent dust and other contaminants from entering the shell and contaminating the standard sample block.

[0021] 3. The light source selected in this invention is a green light source, especially a green light source with a wavelength of 555nm. The human eye is more sensitive under this light source, which makes the detection results more accurate.

[0022] 4. The sample placement platform of this utility model is a rectangular platform structure, and the upper surface of the rectangular platform is provided with a groove. The standard sample block is placed in the groove to ensure the stability of the standard sample block during rotation.

[0023] 5. The rotating handle of this utility model has a handle at one end extending from the outer shell, which makes the rotation process more convenient and the testing process more efficient.

[0024] 6. This utility model has a rotatable box structure, which makes it easy for workers to carry to the production site. At the same time, the rotating design makes the sample blocks easy to take out and compare, improving the convenience of workers' operation. Attached Figure Description

[0032] To make the objectives, advantages and features of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 1 and Figure 2 As shown in the figure, this embodiment provides a rotatable box-type surface roughness rapid inspection device, including a housing 1, a rotating sample placement assembly and a light source (not shown in the figure).

[0034] The outer shell 1 is cylindrical and has a hollow internal structure. The diameter of the outer shell 1 is about 15-20cm and the thickness is about 40mm. The overall size is small, it occupies little space, and the manufacturing cost is low.

[0035] The outer shell 1 is provided with a central rod 2, which coincides with the central axis of the outer shell 1 and is connected at both ends to the upper and lower bottom surfaces of the outer shell 1 respectively; the upper bottom surface of the outer shell 1 is provided with an annular groove 11 that is coaxial with the outer shell 1 and communicates with the cavity structure.

[0036] Combination Figure 3 , Figure 4 , Figure 5 As shown, the rotating sample placement assembly is located within the cavity structure and includes a base 3, multiple sample placement platforms 4, and a rotating handle 5. The base 3 is coaxially arranged with the central rod 2 and sleeved on the outside of the central rod 2, and can rotate around the central rod 2.

[0037] Multiple sample placement platforms 4 are evenly distributed around the base 3 and connected to the base 3 via connecting rods 6. Each sample placement platform 4 is used to place standard sample blocks with different surface roughness. In this embodiment, there are five sample placement platforms 4, and each sample placement platform 4 is a rectangular platform with a thickness of 4 to 6 mm. The upper surface of the rectangular platform is provided with a groove 41, the depth of which is about 2.5 mm. Standard sample blocks with different surface roughness are placed in the corresponding groove 41.

[0038] One end of the rotating handle 5 is mounted on one of the connecting rods 6, and the other end extends out of the outer casing 1 through the annular groove 11. An observation window 12 is provided on the upper bottom surface of the outer casing 1. The position of the observation window 12 on the upper bottom surface of the outer casing 1 corresponds to the position of the sample stage 4 in the circumferential direction within the cavity structure. Their shapes and sizes are compatible, and the distance between them and the central rod 2 is consistent. When using this rapid testing device, pushing the rotating handle 5 causes it to rotate along the annular groove 11, simultaneously causing the connecting rod 6 and the base 3 to rotate around the central rod 2, thereby causing each sample stage 4 to rotate synchronously. When the sample stage 4 containing the selected standard sample reaches the observation window 12, the rotation stops.

[0039] To facilitate the pushing of the rotating handle 5, this embodiment also provides a handle 51 at one end of the rotating handle 5 that extends out of the outer casing 1.

[0040] In this embodiment, there are two light sources. A fixed platform 13 is provided on the upper surface of the outer casing 1 near the observation window 12. One light source is installed on the fixed platform 13, and the light-emitting surface of the light source is 1-4 mm higher than the upper surface of the standard sample block. The optical axis forms an angle of 10-20° with the upper surface of the standard sample block and is used to illuminate the standard sample block. The other light source is used to hand-illuminate the product to be tested.

[0041] A green light source with a wavelength of 500-600nm is selected as the light source. Preferably, a green light source with a wavelength of 555nm is selected, because the human eye is more sensitive to green light at a wavelength of 555nm. The focusing and magnification effect of the hyperboloid lens system on the green light can magnify the morphology of the surface of the product under test. In this embodiment, the green light source is 4mm above the sample surface, so that the optical axis of the light emitted by it forms a 15° angle with the surface of the product under test. This can further lengthen the shadow of the surface morphology of the product under test, improve the observation effect, and thus improve the accuracy and reliability of the detection.

[0042] Preferably, the rotating sample placement assembly further includes a protective partition 7, which, along with multiple sample placement stages 4, is evenly distributed around the circumference of the base 3 and connected to the base 3 via a connecting rod 6; the thickness of the protective partition 7 is greater than the thickness of the sample placement stages 4. When the rapid testing device is not in use, pushing the rotating handle 5 rotates the protective partition 7 to the observation window 12, thereby sealing the observation window 12 and preventing dust from contaminating the standard sample block.

[0043] Combination Figures 1 to 5 The usage method of this embodiment is as follows:

[0044] I. Preparation Stage

[0045] First, assemble the rapid testing device described in this embodiment. On the five sample placement stages 4, place the corresponding standard sample blocks in a clockwise order of increasing surface roughness. The roughness of each standard sample block is Ra0.8μm, 1.0μm, 1.3μm, 1.6μm, and 1.8μm, respectively. It is necessary to ensure that the surface of each standard sample block is clean and undamaged.

[0046] II. Usage Phase

[0047] 1. Turn on the light source: Turn on the green light source on the fixed stage 13 to ensure that its light can evenly illuminate the standard sample block in the observation window 12.

[0048] 2. Selecting a Sample: Gently rotate the handle 5 to make the base 3, each connecting rod 6, and the corresponding sample stage 4 rotate synchronously. Stop rotating when the selected standard sample for surface roughness reaches the observation window 12. The standard sample is a sample with the same surface roughness requirement as the product to be tested, and its surface morphology under green light is observed through the observation window 12.

[0049] 3. Comparative testing: Illuminate the surface of the product under test with another green light source and observe the surface morphology of the product under test under this light source. Then, directly compare it with the selected standard sample block. The difference in surface morphology between the two is used to determine whether the surface roughness of the product under test meets the requirements.

[0050] III. Conclusion

[0051] 1. Turn off the light source: After completing the test, turn off the green light source in time to save energy and extend the life of the light source.

[0052] 2. Cleaning and Maintenance: Regularly clean and maintain the rapid testing device to ensure that components such as the observation window 12 and sample placement stage 4 are kept clean and free of dust contamination. Also, check the wear of the rotating handle 5 and the annular groove 11, and replace or repair them promptly if necessary.

[0053] 3. Storage and Protection: When the device is not in use, the protective barrier 7 can be rotated to the observation window 12 position to prevent dust and other contaminants from entering the casing 1 and contaminating the standard sample. At the same time, the entire device should be placed in a dry, well-ventilated environment to avoid moisture or high temperatures.

[0054] Through the above specific implementation steps, the rotatable box-type roughness rapid inspection device of this utility model can realize rapid and accurate detection of surfaces with different roughness, providing strong technical support for production and quality control in related fields.

[0055] This invention innovatively proposes a rotatable box-type rapid surface roughness inspection device that uses green dust detection technology as an auxiliary means. The device has a compact structure, small size, and is easy to operate. By comparing the sample with the part to be produced, it can quickly determine whether the surface roughness of the part meets the production requirements, which can effectively improve the detection efficiency and accuracy and meet the urgent needs of modern manufacturing industry for efficient and precise production tools.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of this utility model.
