There is no need to manually adjust the hardware workpiece 8, which improves the rust removal efficiency of the hardware workpiece 8. At the same time, the rust removal plate 21 can fully contact the hardware workpiece 8 under the elastic force of the spring 19, thereby ensuring the rust removal effect of the rust removal plate 21 on the surface of the hardware workpiece 8.

[0024] Furthermore, two groups of guide grooves are provided on the surface of the rust removal platform 1, and the first bidirectional screw 3 rotates on one group of guide grooves of the rust removal platform 1 through the output shaft of the first motor 2, and the ball screw 11 rotates on the other group of guide grooves of the rust removal platform 1 through the output shaft of the third motor 9. The two groups of guide grooves of the rust removal platform 1 are the same, and the lengths of the first bidirectional screw 3 and the ball screw 11 are the same.

[0025] Furthermore, two groups of first nuts 4 are provided, and the first nuts 4 are rotated by the first bidirectional screw 3 to slide on the guide groove of the rust removal table 1, and the moving directions of the two groups of first nuts 4 are opposite.

The lifting plate 17 drives the rust removal plate 21 to rise and fall, so that the rust removal plate 21 contacts the surface of the hardware workpiece 8. The lifting plate 17 continues to move toward the direction of the hardware workpiece 8, causing the spring 19 to deform. When the rust removal plate 21 and the hardware workpiece 8 are not in close contact, the elastic force of the spring 19 will cause the rust removal plate 21 and the hardware workpiece to be 8 are firmly in contact with each other, at this time, the ball screw 11 is driven to rotate by the output shaft of the third motor 9, and the ball screw 11 drives the moving frame 13 to slide on the surface of the rust removal platform 1 through the second nut 12 during the rotation process, and the moving frame 13 drives the rust removal plate 21 to slide on the surface of the hardware workpiece 8, thereby realizing friction rust removal of the hardware workpiece 8. After the rust removal on both sides of the hardware workpiece 8 is completed, the position of the rust removal plate 21 is adjusted back to its original position, and then the clamping plate 7 is driven to rotate by the output shaft of the second motor 6, and the clamping plate 7 drives the hardware workpiece 8 to rotate on the clamping platform 5, thereby completing the adjustment of the angle of the hardware workpiece 8, which is convenient for friction rust removal on the other two sides of the hardware workpiece 8, and there is no need to manually adjust the hardware workpiece 8, which is more convenient and labor-saving to use.
