Description

Technical Field

[0002] During the processing of wooden doors, after the board is cut, it needs to be polished and shaped. The prior art announcement number is CN218801285U, which discloses a polishing device for solid wood door processing, including: a polishing workbench, a bracket adjustment mechanism and a polishing mechanism. The polishing device for solid wood door processing, the bottom of the first fixing member is connected to the second motor through the first rotating shaft and the connecting rod, and the output end of the second motor is connected with a polishing wheel to polish the solid wood door to be processed. By connecting multiple groups of second fixing members and springs on the outside of the second motor, a slight vibration will be generated during the polishing of the wooden door. The rotation of the first rotating shaft and the second rotating shaft connected by the spring can play a buffering effect. By starting the first motor, the operation of the turntable can be driven, and it can rotate quickly during the polishing process. For polishing different positions of the solid wood door, the solid wood door to be processed can be fixed by screwing the threaded rod to drive the fixing clamp through the installed fixing mechanism to prevent it from offsetting during the polishing process and causing processing damage.
