Description

TECHNICAL FIELD

[0001] The utility model relates to non ferrous metal technical field, concretely relates to a metallographic grinder of automatic purging gas. BACKGROUND

[0002] China's non ferrous metal industry has formed a complete industrial system including mine, smelting, processing and geological exploration, engineering investigation and design, construction, scientific research and education departments after years of construction and development, and metal is usually extracted from mined sandstone, and after the metal is extracted, the extracted metal needs to be detected to determine the density and type of the metal, and the most common detection method is to polish the surface of the metal, polish one side of the metal to be flat, and then corrode it, and then observe the pattern displayed on the surface of the metal, and the metallographic grinder of automatic purging gas is needed when polishing.

[0003] Now the equipment usually places the metal on the surface of the polishing assembly when polishing the metal, and polishes the surface of the metal by rotating the polishing assembly, and sprays water on the polishing assembly and the surface of the metal by using a spray head to ensure that the metal will not change its properties due to overheating.

[0004] Because the metal is hard, a certain pressure needs to be applied to the surface of the metal during polishing, so that the metal can be in full contact with the polishing assembly, but the existing equipment has difficulty in applying effective pressure to the surface of the metal during polishing, which makes it difficult for the polishing equipment to contact the surface of the metal to the polishing assembly, thereby reducing the polishing efficiency and effect of the equipment, which needs the staff to improve the equipment. UTILITY MODEL CONTENT

[0005] Therefore, the utility model solves the technical problem that the existing metallographic grinder of automatic purging gas cannot effectively fix the metal, thereby providing a metallographic grinder of automatic purging gas.

[0006] To achieve the above purpose, the utility model provides the following technical scheme:

[0007] Comprise:

[0008] The bottom of one end of the connecting rod is provided with a fixed rod, the surface of the middle part of the fixed rod is provided with a first fixed plate, the top of the first fixed plate is provided with a first air pump body, the bottom of the first air pump body is provided with a telescopic air rod, and the bottom end of the telescopic air rod is provided with a gasket.

[0009] As an optional technical scheme, one side of the inner wall of the base is provided with a second air pump body, one side of the inner wall of the base is overlapped with a storage box, and the surface of the storage box is provided with a screen.

[0010] As an optional technical scheme, one side of the base is provided with a connecting pipe, and one end of the connecting pipe is provided with a spray head.

[0011] As an optional technical scheme, the inner wall of the base is provided with a first servo motor, and the output end of the first servo motor is provided with a supporting rod.

[0012] As an optional technical scheme, the bottom end of the fixing rod is provided with a second fixing plate, and the inner wall of the second fixing plate is provided with a placing groove.

[0016] The utility model technical scheme has the following advantages:

[0017] 1. The utility model transports gas to the telescopic air rod through the first air pump body, so that the telescopic air rod can be telescopic. The telescopic of the telescopic air rod drives the gasket at the bottom to lift, and the lifting of the gasket pressurizes the metal at the bottom. When polishing, the metal is extruded by the gasket, so that the part of the metal in contact with the polishing assembly can be fully contacted, thereby improving the polishing effect and efficiency of the polishing assembly. In addition, the telescopic distance of the telescopic air rod can be adjusted according to the amount of gas transported by the first air pump body, so that the device can be suitable for more types of metal.

[0018] 2. The utility model blows air to the storage box through the second air pump body, and the gas blows the metal in the storage box through the screen, so that the impurities remaining on the surface of the metal due to polishing are blown away. The blown impurities fall in the inner wall of the base through the screen. This structure can effectively clean the polished metal, and is convenient for subsequent observation and research of the polished metal by the staff. DRAWINGS
