Description

Technical Field

[0001] This utility model belongs to the technical field of grinding equipment, and more specifically, it relates to a metal spectral analysis pretreatment grinding equipment. Background Technology

[0002] In many fields such as the research, production, and quality control of metallic materials, spectral analysis is an extremely important detection method. It can quickly and accurately perform qualitative and quantitative analysis of multiple elements in metals, providing crucial data support for related work. However, to obtain accurate and reliable spectral analysis results, the sample pretreatment process is crucial. During metal smelting, the surface of metal ingots or castings often has problems such as oxide scale, impurities, and casting defects, which can seriously affect the accuracy of spectral analysis. To avoid the influence of metal surface defects on spectral analysis, the surface of metal samples must be treated by grinding equipment. Therefore, a grinding device is needed.

[0003] Based on existing technology, it has been found that when using existing grinding devices, the operator needs to hold the metal sample block and make it directly contact the high-speed rotating grinding wheel to complete the grinding process. However, at the moment the metal sample block contacts the grinding wheel, the high-speed rotation of the grinding wheel generates a strong grinding force, which not only causes strong vibration and discomfort to the operator's hand, but also easily leads to hand fatigue after long-term operation. It is difficult to maintain a stable grip on the metal sample block, causing the metal sample block to easily loosen during the grinding process and accidentally fall from the operator's hand. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model relates to a metal spectral analysis pretreatment grinding device, which solves the problem that at the moment the metal sample comes into contact with the grinding wheel, the high-speed rotation of the grinding wheel generates a strong grinding force, which not only causes strong vibration and discomfort to the operator's hands, but also makes it difficult to maintain a stable grip on the metal sample, resulting in the metal sample accidentally falling from the operator's hand.

[0005] This utility model provides a metal spectral analysis pretreatment grinding device, which is achieved by the following specific technical means:

[0006] A metal spectroscopic analysis pretreatment grinding device includes: a base frame; an inner fixing frame inside the base frame; two sets of side fixing plates fixed to the outer wall of the inner fixing frame; a base plate fixed to the top of the inner fixing frame; two sets of connected internal grooves opened on the top of the base plate; a protective cover plate covering the outer side of the inner fixing frame; two sets of grinding grooves opened on the protective cover plate; a sample fixing cylinder inside the two sets of grinding grooves; an inner locking groove equidistantly opened on the inner wall of the two sets of sample fixing cylinders; a sample clamping head slidably connected inside the inner locking groove; a pusher frame threadedly connected to the top of the sample fixing cylinder; the pusher frame is configured as a threaded rod structure, with a rotating handle at the top of the pusher frame, and a disc-shaped pusher plate fixed to the bottom of the pusher frame, the pusher plate at the bottom of the pusher frame being disposed inside the sample fixing cylinder; a connecting block fixed to the outer side of the two sets of sample fixing cylinders; and an outer clamping bracket fixed to the bottom outer wall of the two sets of connecting blocks.

[0007] Preferably, the inner frame is configured as a U-shaped structure, and two sets of mounting plates are fixed to the inner wall of the inner frame; the inner frame is fixed to the inside of the bottom frame by two sets of side mounting plates; and a drive motor is fixed to the bottom of the inner frame.

[0008] Preferably, the motor shaft of the drive motor is connected to a driving block; a connecting head is connected to the top of the driving block; a transmission belt is connected to the driving block; a driven block is connected to the driving block via the transmission belt; and a connecting head is connected to the top of the driven block.

[0009] Preferably, the center positions of the two sets of built-in grooves are connected to shaft holes; the shaft holes of the two sets of built-in grooves are respectively rotatably connected to the mating joints of the driving block and the driven block; the interiors of the two sets of built-in grooves are respectively rotatably connected to two sets of grinding wheels; the two sets of grinding wheels are respectively connected to the mating joints of the driving block and the driven block.

[0010] Preferably, the protective cover is fixed to the top of the base frame; the top of the protective cover is provided with a circular mating slot; the grinding groove is configured as a fan-shaped groove.

[0011] Preferably, the two sets of sample tubes are cylindrical in shape, and the top of the two sets of sample tubes is provided with threaded through holes; the sample clamping head is spherical in shape, and the sample clamping head is provided with a spring.

[0012] Preferably, the inner side of the outer card holder is fixed with a plug for inserting into the docking slot; the outer card holder is snapped onto the top of the protective cover.

[0013] The metal spectroscopic analysis pretreatment grinding device proposed in this utility model has the following beneficial effects:

[0014] 1. The inner locking groove on the inner wall of the sample holder cooperates with the sample clamping head, and can automatically extend and clamp the metal sample block under the action of the spring, ensuring that the sample remains stable during the grinding process. The top pusher is set as a threaded rod structure. By rotating the handle, the bottom pusher can push the metal sample block to contact the grinding wheel, which can easily and flexibly adjust the degree of contact between the sample and the grinding wheel. It is suitable for metal samples with different grinding requirements, which enhances the applicability of the equipment. The sample holder constrains the metal sample block to prevent the metal sample block and the grinding wheel from being directly transferred to the operator's arm, increasing its stability during the grinding process.

[0015] 2. The protective cover can shield the grinding wheel, preventing it from being completely exposed. This effectively protects the operator's hands during the grinding process and prevents injury from accidental splashes of grinding wheel debris. The fan-shaped groove design of the grinding groove facilitates the placement of the sample holder so that the metal sample block can contact the grinding wheel, while also limiting the splash range of grinding wheel debris to a certain extent, further improving the safety of the equipment.
