[0002] In furniture production, round tables, round benches and other furniture assembled from round wooden boards are beautiful and well-loved. However, during the processing of round wooden boards, they need to be polished to avoid burrs that affect the quality of the boards and the user experience. Most existing polishing devices are used to polish flat surfaces, but the curved surfaces of round wooden boards cannot be polished automatically. Most of them require operators to use handheld polishing equipment for manual polishing, which is not only inefficient, but also has unstable polishing quality.

[0003] To this end, Chinese patent publication number CN112476082A discloses a round wood board grinding device, which is simple to operate. The round wood board is rotated by a motor-driven rotating shaft, and then the grinding groove is pulled to make the round wood board contact with each other for grinding. With the help of the gravity of the counterweight block itself, after the handle is released, the grinding groove automatically breaks away from the contact with the round wood board.

[0004] However, when installing wood, the existing grinding device needs to ensure that the axis of the wood is aligned with the axis of the drive shaft of the motor used to drive the wood to rotate, thereby ensuring the processing quality, and it can only grind wood of fixed size. Nowadays, high-end furniture is usually customized with different sizes, so it takes a long time to debug the equipment before processing the wood.

The wood 5 is a round wooden board. When grinding, the operator moves the wood 5 to the workbench 1 through a robotic arm or other tools, and makes the wood 5 lie flat. Then, the synchronous adjustment mechanism 2 controls the positioning wheel 111 and the grinding wheel to move simultaneously toward the axis direction close to the workbench 1. If the axis of the wood 5 is Deviating from the axis of the workbench 1, the wood 5 is pushed after the positioning wheel 111 contacts the curved surface of the wood 5 until the three positioning wheels 111 are all in contact with the curved surface of the wood 5, and then the position of the wood 5 is accurately and quickly positioned by pushing at least three positioning wheels 111. During the movement of the positioning wheel 111, the synchronous adjustment mechanism 2 will also control the synchronous movement of the grinding roller 121, so that the outer ring of the grinding roller 121 contacts the curved surface of the wood 5. Then the operator sends a signal to the first rotary driver 13 through the controller. After receiving the signal, the first rotary driver 13 drives the grinding roller 121 to rotate.
