Because the spring 555 is in the state of being stretched to the maximum value, when the conveying belt 52 transports the polished workpiece to the placement disc 554, the placement disc 554 is pressed downward due to the weight of the workpiece, so that the whole moves. When the telescopic rod 553 is compressed to the minimum value, the driving motor B551 controls the rotating disc 552 to rotate, so as to continue to store the workpiece.

[0051] As shown in Figure 11 , the clamping assembly 6 includes a cylinder B61 and a clamping jaw 63. The cylinder B61 is located on one side of the shroud support 22.

[0053] As shown in the figure, the air cylinder B61 is electrically connected with the Hall element 56 through the control panel. Figures 9-11

[0054] Specifically, when the magnetic field detected by the Hall element 56 is the maximum value, the electric push rod 53 works with the air cylinder B61, when the air cylinder B61 is elongated to the position of the workpiece, the air source member 62 works to control the clamping jaw 63 to clamp the workpiece, and then the air cylinder B61 is retracted;

[0055] Working principle: the staff places the unpolished workpiece in the warehouse body A54, and then the conveying belt 52 moves, the placing groove 522 in the conveying belt 52 cooperates with the workpiece to drive the workpiece to move, due to the structure of the rod body 58, the upper surface of the conveying belt 52 will not contact the workpiece when the conveying belt 52 moves, when the workpiece moves to the upper end of the electric push rod 53 through the conveying belt 52, the magnetic force measured by the Hall element 56 is the maximum value, the signal measured by the Hall element 56 controls the movement of the electric push rod, the workpiece is moved, then the clamping assembly 6 works to control the workpiece to move to the clamping workpiece 29, the clamping workpiece 29 fixes the workpiece, and cooperates with the polishing head 33 to polish the workpiece, through the cooperation of the slide saddle assembly 2 and the polishing shaft assembly 3, the workpiece is polished at multiple axial angles, after polishing, the clamping assembly 6 works to clamp the workpiece, controls the workpiece to return to the top end of the electric push rod, when the workpiece is placed on the electric push rod, the pressure-sensitive element 57 is pressed, the electric push rod is retracted to make the workpiece return to the placing groove 522, and finally the workpiece is brought to the warehouse body B55, when the conveying belt 52 transports the polished workpiece to the placing disc 554, because of the weight of the workpiece, the placing disc 554 will press the spring 555 downward to move the whole body, so that the workpiece can be continuously stored.
