Water grinding head for diamond dust-free pump

Abstract

The invention relates to a grinding head, in particular to a water grinding head for a diamond dust-free pump. The water grinding head comprises a grinding disc and a diamond integral grinding ring, wherein an axle hole is formed in the center of the grinding disc; the diamond integral grinding ring is fixed on the grinding disc and is coaxial with the grinding disc; the two end faces of the grinding disc are provided with a small flange and a large flange respectively; locking holes are uniformly formed in the circumference of the small flange; bolts and water supply holes are uniformly formed in the circumference of the large flange; an annular channel plate and a disc body which are arranged at the edge of the large flange form a water storage channel; water pumping blades which are matched with the water supply holes are arranged in the water storage channel; and the diamond integral grinding ring is arranged on the large flange through an assembly hole. In the grinding head, the grinding disc has a water storage function, and the water pumping blades are arranged in the water storage channel to supply water for a working surface of the diamond grinding ring, so that an alloy substrate of the grinding ring is cooled, diamond particles dropped due to normal wearing of grinding blocks and abrasive dust ground off by a ground surface are removed, the grinding efficiency of the grinding head is increased, and the service life of the grinding head is prolonged.

Description

technical field [0001] The utility model relates to a grinding head, in particular to a diamond dust-free pump water grinding head. Background technique [0002] At present, my country's inorganic non-metallic (stone, refractory materials, building ceramics, etc.) processing and manufacturing industries generally use fixed grinders or mobile electric tools to process planes with grinding discs and diamond grinding blocks. The existing methods have problems such as large dust pollution, low efficiency, serious waste of resources, and poor occupational health and environment. In the process, water-added wet grinding and vacuum cleaners are generally used to solve the problem. However, due to the high-speed rotation of the grinding head, the cooling of the dust removal Water cannot be added to the working surface that generates dust and thermal friction, which leads to a large amount of dust during the grinding process, and the temperature of the diamond working surface rises r...

Problems solved by technology

The existing methods have problems such as large dust pollution, low efficiency, serious waste of resources, and poor occupational health and environment. In the process, water-added wet grinding and vacuum cleaners are generally used to solve the problem. However, due to the high-speed rotation of the grinding head, the cooling of the dust removal Water cannot be added to the working surface that generates dust and thermal friction, which leads to a large amount of dust during the grinding process, and the temperature of the diamond working surface rises rapidly, causing the diamond particle matrix alloy to expand when heated, and even slightly melted, which promotes the diamond particles from the alloy matrix. The upper part falls off, which greatly affects the grinding effect and greatly reduces the service life of the grinding head, making it difficult to achieve the expected effect
