Description
Technical Field
[0001] The utility model relates to the field of processing machinery, in particular to a bridge-type diamond grinding wheel brick grinding machine, belonging to processing equipment for processing refractory materials and non-metallic materials. Background Art
[0002] Refractory products such as high-alumina bricks, clay bricks, and high-quality silica bricks are widely used in metallurgy, building materials (cement and glass), non-ferrous metal smelting, petroleum, chemical industry, electric power, and machinery manufacturing. After firing, many large refractory bricks need to be ground as required. This grinding process is usually completed on a surface grinder, but the current surface grinder can only process one plane at a time, and because the grinding head of the surface grinder is fixed, the position of the grinding head cannot be adjusted. Therefore, this type of processing not only has low processing efficiency, but also large processing errors, and it is difficult to ensure processing accuracy.
[0003] Due to the harsh machining and grinding environment of refractory materials, in addition to a lot of large dust, there is also a large amount of gouache and mud ground down to form abrasives, which causes severe wear on all the fixed guide rails and movable slide rails of the milling and grinding machine, resulting in a large gap between the guide rails and the movable slide rails, seriously affecting the machining accuracy, and causing the grinding head to vibrate, so that the precision of the refractory materials being processed seriously fails to meet the requirements. Due to the large gap between the guide rails and the movable slide rails, it is very easy to cause the corners of the refractory bricks to fall off, resulting in a large amount of waste. Therefore, it has to be overhauled in less than a year or so, resulting in increased maintenance costs and a large waste of manpower and material resources. After several consecutive overhauls, the milling and grinding machine tools were scrapped and new processing equipment had to be purchased.
[0004] In addition, the traditional single-column brick grinding machine can grind small bricks and cannot process refractory bricks with a length of 600-1000mm, which cannot meet production needs. Moreover, the single column has poor stability and can only be used for small bricks. Utility Model Content

The upper guide rail 204 is connected to the side plates 208 on both sides, and the lower part of the side plates 208 is connected to the web plate 209. The upper guide rail 204 moves in a straight line to drive the main beam slide and the grinding mechanism to move left and right along the main beam 103, and drives the diamond grinding wheel 223 to move left and right, so as to achieve the purpose of grinding processing. The side plates 208 and the webs 209 are provided with 8 guide wheels 210 to ensure the straightness of the main beam slide and the grinding mechanism, so as to make the travel smooth.

[0048] When the diamond grinding wheel 223 processes the brick material 313, the variable frequency motor 211 rotates, driving the motor pulley 212, which is transmitted to the main shaft pulley 214 through the V-belt 213, driving the main shaft 215 to rotate, and through the steel key 216 and the anti-loosening pressure cover 217, the left waterproof cover 218, the bearing 220, the right waterproof cover 222, the diamond grinding wheel 223, the grinding wheel steel key 224, the fastening nut 225, the inner waterproof cover 226, the taper sleeve 227, the bearing spacer 228, the pre-tightening nut 229, etc. rotate with the main shaft 215 to achieve the processing of the diamond grinding wheel 223. The outer waterproof fixed cover 219, the inner waterproof cover 221, the bearing cover 230, the bearing seat 231, and the bearing seat anti-loosening base 232 seal and fix the main shaft 215 and related parts, and the variable frequency motor 211 is equipped to make the diamond grinding wheel 223 rotate steplessly. When grinding, the appropriate number of revolutions is adjusted according to the hardness of the brick material to achieve the best effect. Below the diamond grinding wheel 223 is the workbench assembly part, and multiple bricks 313 can be placed on the workbench 301 for simultaneous processing, saving time and effort. The motor 104 on the upper beam 101 drives the lifting worm reducers 109 on both sides to rotate the lifting screw 110, driving the main beam 103 and the diamond grinding wheel 223 thereon to rise and fall, thereby realizing the grinding process.
