[0001] The utility model relates to the technical field of vertical surface grinders, in particular to a grinding wheel replacement mechanism for a vertical surface grinder. Background Art

[0002] Surface grinder is a commonly used tool for grinding metal products. It has the advantages of more careful grinding, higher precision, higher work efficiency, higher operating safety and higher reliability. Vertical grinder is a grinder installed on a column. Its base supports the column. There are three sets of pulleys horizontally and three sets of pulleys vertically spread on the column. The grinding head is set on the top. The support and transfer motors are installed on the base to reduce vibration and noise. The solid base supports all major parts. The entire grinding head can run and position accurately to achieve high precision with tight cracks, flat and smooth surfaces.

[0003] The existing vertical surface grinder needs to manually remove multiple bolts used to fix the grinding wheel with a wrench before the grinding wheel can be removed, which is rather troublesome. In addition, since the surface of the grinding wheel is uneven after being worn, there is a risk of scratching the hands when directly touching it with hands. When replacing and installing the grinding wheel of the existing vertical surface grinder, it is generally supported manually, and there is a risk of the hand slipping and falling off, causing damage to the grinding wheel. Therefore, a grinding wheel replacement mechanism for a vertical surface grinder is proposed to address the above problems. Utility Model Content

[0014] 1. In the utility model, by setting the fixed shell, the first limiting groove, the first fixing block, the second limiting groove, the second fixing block, the first rotating shaft, the second rotating shaft, the first gear, the second gear, the third limiting groove, the fourth limiting groove and the motor and other components, the first rotating shaft, the first gear and the second fixing block are driven to rotate by the motor, and the nut on the outer side of the first fixing shaft is screwed off by the second fixing block. While the first rotating shaft rotates, the first gear on the outer side of the first rotating shaft drives the five second gears to rotate, and the five second rotating shafts and the five first fixing blocks are driven to rotate by the five second gears, and the nuts on the outer sides of the five second fixing shafts are screwed off at the same time by the five first fixing blocks. Due to the first gear and the second gear, the rotation speed of the second rotating shaft and the first rotating shaft is consistent. Through the above operation, the six nuts on the surfaces of the first fixing shaft and the second fixing shaft can be screwed off at the same time, thereby solving the problem that the existing vertical surface grinder needs to manually remove multiple bolts for fixing the grinding wheel with a wrench before the grinding wheel can be removed, which is relatively troublesome, and because the surface of the grinding wheel is uneven after wear, there is a risk of scratching the hand if it is directly touched by hand;

[0015] 2. In the utility model, by providing components such as a fixed shell, a rubber layer, rubber bumps, a handle and an armrest, and by providing the rubber layer and the rubber bumps on the inner side of the fixed shell, the friction between the fixed shell and the grinding wheel can be greatly increased, so that the grinding wheel can be firmly clamped on the inner side of the rubber layer. By holding the entire device and the grinding wheel with both hands through the provided handle and the armrest, the overall device and the grinding wheel can be held more stably, thereby solving the problem of manual support when replacing and installing the grinding wheel on the existing vertical surface grinder, which has the risk of slipping and falling off, causing damage to the grinding wheel.
