A threaded rod 52 is provided between the two front mounting plates 51 via a bearing. A knob is provided at one end of the threaded rod 52. A guide rod 53 is fixedly connected between the two rear mounting plates 51. Movable blocks 54 are sleeved on the outer walls of both the threaded rod 52 and the guide rod 53. The inner wall of the movable block 54 on the guide rod 53 is slidably connected to the outer wall of the guide rod 53. The inner wall of the movable block 54 on the threaded rod 52 is threadedly connected to the outer wall of the threaded rod 52. Slider blocks 55 are fixedly connected to the front and rear ends of the bottom side of the movable block 54. The outer wall of the slider 55 is slidably connected to the inner wall of the slide groove 41. The fixed plate 4 is fixedly connected to the front and rear sides of one end. There is a mounting plate 571, and a rotating shaft 572 is rotatably connected between the mounting plates 571. A connecting plate 573 is fixedly connected to the front and rear sides of the outer wall of the rotating shaft 572. A support plate 57 is fixedly connected to the upper end of the connecting plate 573. An adjusting plate 56 is movably connected to the upper end of the movable block 54 through a hinge seat. The other end of the adjusting plate 56 is movably connected to the bottom side of the support plate 57 through a hinge seat. A polishing angle adjustment device 5 is installed, which can adjust the angle of contact between the polishing wheel 63 and the workpiece, thereby matching various surface structures. The user can adjust the angle of the polishing wheel 63 by rotating the knob to make the adjusting plate 56 pull the support plate 57 to tilt. The adjustment is convenient and easy to operate.

[0027] like Figure 3 and Figure 4 As shown, the output end of the drive motor 6 is equipped with a drive shaft 61. Positioning grooves 611 are provided on both sides of the inner wall of the drive shaft 61. Locking screw holes 612 are equidistantly provided around the outer surface of the positioning grooves 611. Locking bolts 613 are threadedly connected between locking screw holes 612 and 621. A connecting rod 62 is engaged inside the drive shaft 61. Positioning plates 622 are fixedly connected to the outer walls of both sides of the connecting rod 62. The outer walls of the positioning plates 622 are slidably connected to the inner walls of the positioning grooves 611. Locking screw holes 621 are equidistantly provided around the outer surface of the connecting rod 62. A locking block 623 is fixedly connected to one end of the connecting rod 62.

[0028] This utility model provides a polishing machine that facilitates grinding wheel replacement. The specific working principle is as follows: During polishing, to adapt to workpieces of different shapes, the angle of the polishing wheel 63 needs to be adjusted. This is achieved by rotating a knob to rotate the threaded rod 52, causing the movable block 54 to move on the threaded rod 52 and guide rod 53. This allows the support plate 57 to be tilted via the adjusting plate 56, thus adjusting the angle of the polishing wheel 63. When the worn polishing wheel 63 needs to be replaced, firstly, remove the locking bolt 613 between locking screw hole one 612 and locking screw hole two 621, allowing the connecting rod 62 to be removed from the drive shaft 61. Then, remove the bolt between the limiting plate 65 and the polishing wheel 63, and rotate the limiting plate 65 to remove it from the screw 624. This allows the polishing wheel 63 to be pulled out from the locking block 623 for replacement.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
