Description

Technical Field

[0001] This utility model relates to the technical field of steel chemical analysis equipment, specifically a fixture for grinding direct-reading spectral steel standards. Background Technology

[0002] In order to quickly obtain the chemical composition indicators of steel and steel products during the steel production process, direct-reading spectrometers are often used for analysis. Before the analysis of direct-reading spectrometers, standard samples must be used to verify the accuracy. Therefore, the daily usage of standard samples is relatively large. Before using standard samples for verification, the analytical surface of the standard sample must be ground to remove the contamination layer and ensure the accuracy of the analysis. Therefore, the standard sample is ground every time it is analyzed. The daily grinding is done by holding one end of the standard sample by hand on a belt sander. When the height of the standard sample is less than 20 mm, it is impossible to grind it by hand. The standard sample is too small to hold and may fly out and injure people. At the same time, the heat generated by grinding the standard sample may burn the hands. Small standard samples that cannot be ground are discarded, resulting in waste. To address this, we propose a fixture for grinding direct-reading spectrometer steel standard samples. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 A fixture for grinding direct-reading spectral steel standards includes a handle 1, a rotating cylinder 2 movably mounted above the handle 1, a protective cover 6 mounted above the rotating cylinder 2, a trapezoidal threaded screw 8 passing through the interior of the rotating cylinder 2, a limiting telescopic hole 14 opened inside the trapezoidal threaded screw 8, a limiting telescopic column 12 passing through the limiting telescopic hole 14, a connecting bearing 13 fixedly mounted at the bottom of the inner wall of the rotating cylinder 2, a flange 9 fixedly mounted at the top of the trapezoidal threaded screw 8, a strong magnet 5 bolted above the flange 9, and a locking screw 7 threadedly mounted at the front end of the rotating cylinder 2.

[0021] In this implementation plan, a strong magnet 5 quickly attracts the standard sample, which is then protected by an adjustable protective cover 6. This effectively solves the safety hazards of standard samples flying out and causing injury or burns during traditional manual grinding. This fixture can safely and stably grind standard samples of various sizes, including those less than 20mm in height, improving the smoothness of the ground surface and analytical accuracy. It also significantly increases work efficiency and greatly reduces waste and costs by extending the service life of small standard samples. Its simple design, low manufacturing cost, and convenient operation make it highly valuable for widespread application.

[0022] Furthermore:

[0023] In an optional embodiment, the shape and size of the limiting telescopic post 12 match the shape and size of the inside of the limiting telescopic hole 14, and the limiting telescopic post 12 is fixedly connected to the handle 1.

[0024] In this implementation scheme: when the trapezoidal threaded screw 8 retracts into the handle 1, the limiting telescopic column 12 retracts into the limiting telescopic hole 14. The limiting telescopic column 12 and the limiting telescopic hole 14 cooperate to restrict the trapezoidal threaded screw 8 and prevent the trapezoidal threaded screw 8 from rotating inside the handle 1.

[0025] Furthermore:

[0026] In an optional embodiment, the rotating cylinder 2 is threadedly connected to the trapezoidal threaded screw 8, and the rotating cylinder 2 is movably connected to the handle 1 via a connecting bearing 13.

[0027] In this implementation scheme: when the rotating cylinder 2 is rotated clockwise or counterclockwise, the trapezoidal threaded screw 8 can be pushed to extend and retract inside the handle 1, thereby causing the rotating cylinder 2 to press against the adjusted protective cover 6.

[0028] Furthermore:

[0029] In an optional embodiment, the trapezoidal threaded screw 8 extends through the interior of the protective cover 6, and the protective cover 6 is threadedly connected to the trapezoidal threaded screw 8.

[0030] In this implementation plan: the position of the protective cover 6 can be adjusted by rotating the protective cover 6 to meet the usage requirements.

[0031] Furthermore:

[0032] In an optional embodiment, the strong magnet 5 has a disc-shaped structure, and the diameter of the strong magnet 5 matches the diameter of the flange 9, while the diameter of the strong magnet 5 is smaller than the diameter of the inside of the protective cover 6.

[0033] In this implementation plan, the above-mentioned technology ensures that the strong magnet 5 can move smoothly inside the protective cover 6.

[0034] Furthermore:

[0035] In an optional embodiment, the protective cover 6 further includes:

[0036] The sampling plate 3 is installed above the protective cover 6. The sampling plate 3 has an ejector screw 4 inside. The outer surface of the sampling plate 3 has two combination holes 10. The combination holes 10 have combination columns 11 inside. The combination columns 11 are fixedly connected to the sampling plate 3. The sampling plate 3 has an arc-shaped structure. The sampling plate 3 is detachably connected to the protective cover 6 through the combination holes 10 and the combination columns 11.

[0037] In this implementation plan, the above-mentioned technology facilitates the removal of the ground sample from the strong magnet 5, and also makes the installation and removal of the sampling plate 3 simple and convenient.

[0038] Working principle: When using this fixture for grinding steel standards for direct-reading spectrometers, first hold handle 1 and turn the fixture protective cover 6 to align its end face with the plane of the strong magnet 5. Place the standard sample, and the strong magnet 5 will firmly hold the standard sample. Then, turn the protective cover 6 again to adjust its end face to a position slightly lower than the end face of the standard sample. Next, turn the rotating cylinder 2, which will push the trapezoidal threaded screw 8 inward through the thread, causing the rotating cylinder 2 to press against the protective cover 6. Then, tighten the locking screw 7 on the rotating cylinder 2 to make the rotating cylinder 2 and the locking screw 7 relatively stationary. Then, hold the fixture handle 1 and grind on a belt sander until the grinding requirements are met. Finally, assemble the sampling plate 3 onto the protective cover. Above the cover 6, insert the combined column 11 into the combined hole 10, then readjust the position of the protective cover 6 so that the end face of the protective cover 6 is lower than the bottom position of the standard sample, and then turn the ejector screw 4 to push the ejector screw 4 to move through the thread, thereby pushing the standard sample on the strong magnet 5 down, thus removing the standard sample. When the trapezoidal threaded screw 8 retracts into the handle 1, the limiting telescopic column 12 retracts into the limiting telescopic hole 14. The limiting telescopic column 12 and the limiting telescopic hole 14 cooperate to restrict the trapezoidal threaded screw 8, preventing the trapezoidal threaded screw 8 from rotating inside the handle 1. This is the working principle of the fixture used for grinding direct-reading spectral steel standard samples.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
