Description

Technical Field

[0001] The utility model relates to the field of polishing machine disassembly, in particular to a bearing removal device on a polishing shaft. Background Art

[0002] Magnesium alloy is an alloy composed of magnesium and other elements. The characteristics of magnesium alloy are: low density (about 1.8g / cm3), high strength, large elastic modulus, good heat dissipation, good shock absorption, greater impact load bearing capacity than aluminum alloy, and good resistance to organic and alkali corrosion. The main alloying elements of magnesium alloy are aluminum, zinc, manganese, cerium, thorium, and a small amount of zirconium or cadmium. The most widely used is magnesium-aluminum alloy, followed by magnesium-manganese alloy and magnesium-zinc-zirconium alloy. It is mainly used in aviation, aerospace, transportation, chemical industry, rocket and other industrial sectors. Thanks to the transformation and upgrading of China's automobile industry and 3C industries and the significant improvement of China's economic status, the magnesium alloy industry is optimistic about the market. Among them, the lightweight and environmental protection needs of the automobile industry, especially the development of new energy vehicles, and the continuous progress of magnesium alloy research and development technology and recycling technology will be good news for the widespread application of magnesium alloys.

[0003] However, magnesium alloys need to be polished during processing. The magnesium alloy polishing machine has a shaft with a polishing wheel installed on it, and the shaft drives the polishing wheel to rotate. When the surface of the magnesium alloy ingot contacts the high-speed rotating polishing wheel, the surface of the magnesium alloy ingot is polished. When inspecting and repairing the shaft of the polishing machine, the bearing on the shaft needs to be removed. The process of disassembling the bearing is done manually, which is inefficient and easy to damage the bearing. Utility Model Content
