Polishing device for door and window plate production

The utility model discloses a polishing device for door and window plate production, belongs to the technical field of polishing equipment, and aims to solve the problems that the polishing angle and the polishing position cannot be adjusted freely in the prior art and polishing errors are caused by deviation of plates when the polishing pressure is too large. Two symmetrical clamping assemblies are slidably mounted on the two guide rods, a top frame is connected to the side face of the base through a main support, a control switch set is mounted on the side face of the main support, a moving assembly is mounted in the top frame, and a dust removal assembly for collecting dust generated during grinding is mounted on the moving assembly. The problem of left-right positioning is solved through a second electric telescopic rod in the positioning assembly, the accuracy of left-right positioning in the grinding process can be further accurate, meanwhile, the problem of front-back positioning accuracy in the front-
