[0001] This invention relates to the field of material surface treatment, and more particularly to a double-sided polishing device. Background Technology

[0002] In the industrial production field, surface polishing of workpieces (such as metal components, wooden boards, plastic parts, etc.) is a key process to ensure product precision, appearance and adaptability to subsequent processing. Especially when the workpiece needs to achieve double-sided smoothness and flatness, the efficiency and quality of the polishing process directly affect production capacity and finished product qualification rate.

[0003] Chinese patent CN222154939U discloses a double-sided automatic grinding device for sheet-like workpieces. This device uses two grinding wheels with opposing end faces for grinding sheet-like workpieces. The workpiece is vertically positioned between the two grinding wheel end faces via a feeding unit, and grinding is performed directly on both sides. After grinding, the workpiece is automatically unloaded and transported outside the device. However, this device is more suitable for sheet-like workpieces of specific sizes. For thin or easily deformable sheet-like workpieces, the direct contact with the grinding wheels may cause workpiece displacement or damage during the flipping process.

[0004] Therefore, it is necessary to develop a double-sided polishing device to solve the above problems. Utility Model Content

When it reaches the corresponding position, the grinding device 3 located on one side of the second conveyor assembly 22 is activated to grind the second side of the workpiece in the same working mode as the first grinding. The workpiece that has completed double-sided grinding is conveyed to the end by the second conveyor assembly 22 for unloading and collection.

[0041] This utility model is a double-sided grinding device, which is stable and has high grinding efficiency. The fixed bracket and the moving bracket form a stable angle structure, which can ensure that the grinding structure always maintains the preset tilt angle with the conveying device during the working process. The grinding angle will not be deviated due to the reaction force of the workpiece, thus maintaining stability. At the same time, the adjustment part pushes the grinding structure to cooperate with the conveying device to achieve high-efficiency grinding.
