In order to improve many shortcomings and deficiencies of the existing grinding equipment, the utility model proposes a tile grinding machine, and its technical scheme is as follows: it includes two columns at the front and rear, and the tops of the two columns are provided with connecting flanges, The top of the connecting flange is jointly supported and fixed with a top beam, a fixed shaft is arranged at the center of the top beam, and a swinging square arm is fixed vertically on the fixed shaft, and the left or right side of the fixed shaft is A swing arm drive motor is provided, and the swing arm drive motor drives the swing square arm to swing with the fixed rotating shaft as the center of the circle through the belt or chain. The swing square arm is a square hollow column, and the bottom end is provided with a connecting thread. connected, the fixed arm of the grinding wheel can be adjusted up and down at the bottom of the swinging square arm through the connecting thread, the center of the bottom end of the fixed arm of the grinding wheel is a fixed shaft, and a circular grinding wheel is fixed on the fixed shaft; At the bottom, a connecting beam is respectively extended from the inner side of the two uprights. The connecting beam is connected with a fixed base through a flange. A workpiece moving and fixing platform is fixed on the top of the sliding track, a driving motor is arranged at the end of the fixing base, a threaded driving shaft is connected to the driving motor, the threaded driving shaft is connected to the bottom of the workpiece moving and fixing platform, and is threaded The drive shaft drives the workpiece moving and fixed platform to move back and forth in the X direction of the sliding track.

The beneficial effects of the utility model are as follows: the utility model sets a fixed rotating shaft at the center of the top beam, drives the swing arm to drive the motor, drives the swinging square arm to swing with the fixed rotating shaft as the center of the circle, and drives the circular grinding wheel to do arc motion at the same time. At this time, the moving and fixed platform of the workpiece is driven by the drive motor to make reciprocating motion on the X axis, and at the same time drives the workpiece to reciprocate. With the arc movement of the grinding wheel, the arc surface of a single assembled workpiece can be polished, and the grinding accuracy is high. With good effect and fast speed, it is an ideal grinding equipment for arc surface of large workpieces.
