Description

Technical Field

[0001] This utility model relates to the field of installation fixtures for sample testing, and in particular to a sample surface roughness measuring device. Background Technology

[0002] In physical property measurement experiments, the surface roughness of the specimen is an important factor, especially affecting experiments sensitive to stress concentration. Therefore, many tests require the measurement of the specimen's surface roughness.

[0003] Surface roughness measurement often utilizes a surface roughness measuring instrument. This instrument offers advantages such as small size, low error, and rapid reading. However, because it requires relative leveling to ensure the sample's test surface is horizontally aligned with the instrument's probe, operation is not always convenient. This is especially true when testing multiple samples from the same batch; if a sample's test surface deviates significantly from the instrument's probe's horizontal alignment, the roughness value of that sample will show a marked difference compared to other samples in the same batch.

[0020] See Figures 1 to 8 This utility model discloses a sample surface roughness measuring device, which can be used to measure the surface roughness of a sample, including but not limited to a flat plate sample, which can be a metal sample or a non-metal sample.

[0021] See Figures 1 to 8The sample surface roughness measuring device may include a mounting platform 10 and a sliding platform 20. The mounting platform 10 is provided with a guide groove 11 for mounting the sliding platform 20.

The surface roughness measuring instrument may be selected from existing technology and has a telescopic probe, which can be selected and set according to actual needs, and is not specifically limited here.

[0022] The sliding stage 20 is movably mounted on the guide groove 11. The moving direction of the sliding stage 20 is perpendicular to the telescopic direction of the telescopic probe. The sliding stage 20 has a first end and a second end arranged along its moving direction. The upper surface of the sliding stage 20 is provided with a receiving groove 21 for mounting the zero-adjustment test plate 30. The receiving groove 21 is located near the first end of the sliding stage 20. The second end of the sliding stage 20 is provided with a handle 22, which can be a U-shaped structure. The zero-adjustment test plate 30 can also be defined as a reference plate. The bottom surface of the sliding stage 20 is a plane.

[0023] The upper surface of the sliding stage 20 is provided with a plurality of limiting grooves 23 for sample mounting, extending from the side near the receiving groove 21 towards the second end of the sliding stage 20. The limiting grooves 23 can be used to place samples of different sizes, and the bottom surface of the limiting grooves 23 is a plane. In some embodiments, the telescopic probe can be telescopic in a direction parallel to the length direction of the mounting platform 10, and the sliding stage 20 can be moving in a direction parallel to the width direction of the mounting platform 10.

[0024] In this embodiment, the mounting slot 12 of the mounting platform 10 holds the surface roughness measuring instrument, and horizontal measurement is achieved by utilizing the horizontal movement of the sliding stage 20. After zeroing the surface roughness measuring instrument by placing the zeroing test plate 30 in the receiving slot 21 of the sliding stage 20, the operator uses the handle 22 to push and pull the sample for measurement. The sliding stage 20 is equipped with limiting slots 23 of different sizes to accommodate different sample sizes, meet measurement requirements, and improve the practicality and applicability of the device.

[0025] Combination Figures 1 to 6In some embodiments, the mounting platform 10 is generally a rectangular columnar structure, and its bottom surface is flat. One end of the mounting platform 10 may be provided with a guide groove 11, which is used to guide and limit the sliding stage 20.

[0027] like Figure 4 As shown, in some embodiments, the opposite side of the sidewall of the limiting groove 23 is provided with a protrusion 25 that cooperates with the guide groove 111.

[0032] In some embodiments, the parallelism between the bottom surface of the mounting groove 12 and the bottom surface of the limiting groove 23 is less than or equal to 0.1 mm. In some embodiments, the flatness of the bottom surface of the mounting groove 12 is less than or equal to 0.05 mm.

[0033] In some embodiments, the roughness of the bottom surface of the mounting groove 12 is less than or equal to 5 μm.

For example... Figure 9 As shown, the dimensions of the zeroing test plate 30 can be 30mm*55mm*2mm, and the surface roughness of the zeroing test plate 30 is 0.72μm.

[0035] In some embodiments, both ends of the limiting groove 23 extend through both sides of the sliding table 20 in the width direction. The width direction can be perpendicular to the length direction of the sliding table 20, while the length direction of the sliding table 20 is parallel to its moving direction. The length of the limiting groove 23 along the width direction of the sliding table 20 can be 55 mm.

[0036] like Figure 4 As shown, in some embodiments, the limiting groove 23 may include a first limiting groove 231, a second limiting groove 232, a third limiting groove 233, a fourth limiting groove 234, a fifth limiting groove 235, a sixth limiting groove 236 and a seventh limiting groove 237 arranged sequentially along the moving direction of the sliding table 20; the first limiting groove 231 is arranged on the side closer to the receiving groove 21 and the seventh limiting groove 237 is arranged on the side closer to the handle 22.

[0037] The first limiting groove 231 has a length of 10.25 mm along the moving direction and a maximum depth of 12 mm, making it suitable for placing the first sample 40. Figure 10 As shown, the first sample 40 can be a rectangular columnar structure with dimensions of 10mm*10mm*55mm.

[0038] The second limiting groove 232 has a length of 10.25 mm along the moving direction and a maximum depth of 9.5 mm, making it suitable for placing the second sample 50. Figure 11As shown, the second sample 50 can be a rectangular columnar structure with dimensions of 10mm*7.5mm*55mm.

[0039] The third limiting groove 233 has a length of 10.25 mm along the moving direction and a maximum depth of 7 mm, making it suitable for placing the third sample 60. Figure 12 As shown, the third sample 60 can be a rectangular columnar structure with dimensions of 10mm*5mm*55mm.

[0040] The fourth limiting groove 234 has a length of 10.25 mm along the moving direction and a maximum depth of 4.5 mm, making it suitable for placing the fourth sample 70. Figure 13 As shown, the fourth sample 70 can be a rectangular columnar structure with dimensions of 10mm*2.5mm*55mm.

The seventh limiting groove 237 has a length of 2.75 mm along the moving direction and a maximum depth of 12 mm.

[0042] The direction of movement here can be the length direction of the sliding table 20. Since the top of the side wall of the limiting groove 23 has a positive angle and a negative angle, the maximum depth of the limiting groove 23 refers to the vertical depth from the top surface of the positive angle to the bottom surface of the limiting groove 23.

[0043] In some embodiments, both the mounting platform 10 and the sliding platform 20 can be made of tool steel. In some embodiments, the mounting platform 10 is a single-piece structure. The sliding platform 20 is a single-piece structure.
