Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a spectral standard fixture. Background Technology

[0002] Spectroscopic analysis is a method of identifying substances and determining their chemical composition and relative content based on their spectra. In order to facilitate the testing of standard samples, there are many standard sample fixtures. However, the existing fixtures have a simple structure and cannot be used to hold standard samples of various shapes or sizes. Fixtures that can hold standard samples of various shapes are complex in structure, inconvenient to carry or move, and can easily injure the hands when held after being ground thin, posing a safety hazard. In addition, the standard sample generates heat during the grinding process, and it becomes wasteful to grind the sample by hand after it becomes smaller. Summary of the Invention

[0003] This invention provides a spectral standard sample clamp that is suitable for clamping standard samples of various shapes and sizes. It can safely perform grinding, reduce standard sample consumption, and has a simple structure and low cost.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A spectral standard fixture includes a clamping base, a top cover, a screw, a strong magnet, a clamping body, and a set screw;

[0006] The top cover is fixedly connected to one end of a screw rod, and a strong magnet is fixedly connected to the other end of the screw rod;

[0007] The clamping base has a through hole at its center, and the bottom of the clamping base has a coaxial groove that matches the clamping body. The inner wall of the groove is threaded, and the outer wall of the clamping body is threaded. The clamping body is connected to the clamping base by threads, and the depth of the clamping body is the same as the groove of the clamping base.

[0008] The set screw passes through the holding base and the side wall of the clamping body and is perpendicular to the central axis of the clamping body;

[0009] The screw is connected to a strong magnet that is inserted into the through hole at the end of the clamping base without a groove, and the strong magnet is flush with the bottom surface after the clamping body is installed.

[0010] The inner wall of the through hole of the clamping base is threaded, and the screw is provided with an external thread that matches the inner wall of the through hole of the clamping base. The pushing direction of the screw is the same as the tightening direction of the clamping body.

[0011] Furthermore, the supporting base has a diameter of 60-65mm, a height of 40-60mm, and a weight of no more than 1Kg.

[0012] Furthermore, the top cover has a diameter of 65-70mm, and the side wall of the top cover is provided with anti-slip patterns.

[0013] Furthermore, the depth of the clamping body is less than the thickness of the spectral standard.

[0014] Furthermore, the cross-sectional shape of the clamping body cavity includes octagonal, circular, and square shapes.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1) The screw pushes the strong magnet to firmly attract the standard sample, while also making it easy to remove the strong magnet and take off the standard sample;

[0017] 2) It adopts a variety of clamping bodies that match the clamping base, which are suitable for clamping standard samples of different specifications and shapes. The standard samples are reinforced and fixed by set screws to prevent them from moving around, making the clamping of the standard samples more secure.

[0018] 3) The clamping body is independent of the clamping base, which avoids the problem of easy replacement once the clamping body is worn. Compared with the integrated clamping base, the replacement cost is reduced.

[0019] 4) Using a fixture to hold the standard sample for grinding allows for the safe reuse of the thinned sample, reducing sample consumption and costs. It also eliminates safety hazards caused by manual clamping of the sample. The fixture is easy to use, install, and disassemble, and the device is easy to maintain with low maintenance costs.

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0025] See Figure 1-2 This is a structural schematic diagram of the present invention. The present invention provides a spectral standard sample clamp, comprising a clamping base 1, a top cover 2, a screw 3, a strong magnet 4, a clamping body 5, and a set screw 6;

[0026] The top cover 2 is fixedly connected to one end of the screw 3, and the other end of the screw 3 is fixedly connected to the strong magnet 4; the top cover 2 has a diameter of 70mm, and the side wall of the top cover 2 is provided with anti-slip patterns to facilitate unscrewing and removing the standard sample;

[0027] The clamping base 1 has a through hole at its center, and the bottom of the clamping base 1 has a coaxial groove that matches the clamping body 5, with threads on the inner wall of the groove. Figure 3 The clamping body 5 has external threads on its outer wall, and the inner cavity of the clamping body 5 has an octagonal cross-sectional shape, which can accommodate both circular and square standard samples. The clamping body 5 is connected to the clamping base 1 by threads. The depth of the clamping body 5 is the same as the groove of the clamping base, and the depth of the clamping body 5 is less than the thickness of the spectral standard sample. The clamping base has a diameter of 65 mm, a height of 60 mm, and a weight of 1 kg.

[0028] The set screw 6 passes through the support base and the side wall of the clamping body 5 and is perpendicular to the central axis of the clamping body 5. The set screw 6 is used to adjust the position of standard samples of different sizes and keep the standard sample grinding process stable.

[0029] The screw 3 is connected to a strong magnet 4 which is inserted into the through hole at the end of the clamping base 1 without a groove, and the strong magnet 4 is flush with the bottom surface after the clamping body 5 is installed.

[0030] The inner wall of the through hole of the clamping base 1 is threaded, and the screw 3 is provided with an external thread that matches the inner wall of the through hole of the clamping base. The pushing direction of the screw 3 is the same as the tightening direction of the clamping body 5.

[0031] Working principle: The clamping body 5 is fixed to the support base by external thread. The screw 3 is tightened by the top cover 2, which pushes the magnet to be flush with the bottom surface of the clamping body, so as to firmly adsorb the standard sample. The set screw 6 is adjusted to prevent the standard sample from moving. When grinding square cross-section standard samples, the direction needs to be adjusted to ensure that the grinding direction is perpendicular to the support plane, so as to obtain greater support and ensure grinding quality and safety. After grinding, the top cover 2 is screwed to release the screw 3, which drives the strong magnet 4 to retract, and the standard sample loses its adsorption force. The set screw 6 is loosened and the standard sample is taken out. If clamping standard samples of different specifications and shapes, the clamping body 5 is replaced and the above actions are repeated.

[0032] The above embodiments are implemented based on the technical solution of this utility model, providing detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the above embodiments. Unless otherwise specified, the methods used in the above embodiments are conventional methods.
