Description

Technical Field

[0001] The utility model relates to the technical field of mining production equipment, in particular to a grinding device for manufacturing mining equipment. Background Art

[0002] The grinding device for mining equipment manufacturing is mainly used for fine processing and surface grinding of mining equipment parts. The grinding device can improve the processing accuracy of parts, remove burrs or uneven parts on the surface and the external oxide layer, facilitate later spraying of paint, and improve the corrosion resistance and appearance quality of parts. The design and function of the grinding device for mining production equipment manufacturing are to meet the special needs of mining equipment parts processing and improve processing efficiency and quality.

[0003] When grinding the outside of the ball mill, the grinding device for mining equipment manufacturing usually uses a grinding belt for grinding. When the grinding belt is installed on the grinding device, the grinding belt is first put on the support roller and the rotating roller. The rotating roller rotates to drive the grinding belt to rotate to grind the mining equipment. The rotating roller is supported by the support frame when rotating to maintain the stability of the support roller. However, the existing support frame only supports one side of the rotating roller and the other side has no support. When grinding the mining equipment, the support roller is required to provide support force for the grinding belt to keep the grinding belt and the mining equipment horizontally aligned to ensure the processing accuracy. However, there is no support on the other side of the rotating roller. Long-term operation may cause the support frame to deform and shift to the unsupported side. The support roller will also shift with the support frame. The angle causes the support frame to be unable to keep the support roller and the mining equipment level. After the support roller is offset, it cannot provide support force to the grinding belt, causing the grinding belt to lose power and cannot be used. For this reason, we provide a grinding device for mining equipment manufacturing to solve the above problems. Utility Model Content
