Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a grinding device for producing heat sinks. Background Art

[0002] With the continuous development of electronic equipment, electrical appliances and other industries, the demand for heat sinks continues to grow. As an important heat dissipation device, the quality and performance of heat sinks are crucial to the stable operation of the equipment. In order to ensure the heat dissipation effect and surface quality of the heat sink, it needs to be polished, resulting in a steady increase in demand for polishing devices.

[0003] When the existing grinding device is in use, the heat sink is mostly ground by a grinding wheel. The grinding force of the grinding wheel is large and cannot be adjusted according to the specific situation of the heat sink. It is easy to cause damage to the surface of the heat sink due to excessive grinding. In addition, the grinding angle of the grinding wheel is limited when facing the irregular surface of the heat sink, which affects the uniformity of the grinding.

[0004] Therefore, it is urgently necessary to set up a grinding wheel belt structure that can adjust the grinding force according to different heat sinks, which can meet different grinding needs and better fit the complex shape and contour of the heat sink, including curved parts and corners, and solve the problem that the inability to adjust the grinding force can easily cause damage to the heat sink.

[0027] During operation, the first cylinder 4 first pushes the movable mounting plate 3 to slide on the inner side of the limiting track plate 2, so that the upper grinding belt 611 can play a preliminary role in adjusting the grinding force.
