During the reciprocating movement of the turning shell 765, it contacts the rotating sinking roller 71, thereby deburring the outer wall of the sinking roller 71 and removing residual metal debris, thereby improving the turning effect of the sinking roller 71.

[0034] In Example 2, a cooling component 77 is provided on the inner wall of the square shell 74. The cooling component 77 includes a circular tube 771 fixedly connected to the bottom center of the inner wall of the square shell 74. The top outer wall of the circular tube 771 is slidably connected to the inner wall of the lifting plate 763.

The outer wall of the block 788 is slidably connected to the inner wall of the arc shell 786. One side of the block 788 is fixedly connected to the arc cleaning block 789. When the lifting plate 763 descends, the lifting plate 763 squeezes the rotating plate 781. The rotating plate 781 is limited by the slide groove 783, and the sliding block is driven by the rotating plate 781. 782 slides along the inner wall of the slide groove 783, the slider 782 drives the cross bar 784 to move, the cross bar 784 drives the square bar 785 to move, the square bar 785 drives the arc shell 786 to move, the arc shell 786 drives the block 788 to move, the block 788 drives the arc cleaning block 789 to move, the two arc cleaning blocks 789 approach each other, so that they can contact the top of the turning shell 765 during the descending process, scrape and clean the residual debris on the top of the turning shell 765, and prevent the residual debris from staying on the top of the turning shell 765, affecting the deburring work of the turning shell 765 on the sinking roller 71.

[0038] When in use, the sinking roller 71 is clamped between the inner walls of the two rotating rings 6, and the motor 3 is started. The motor 3 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the belt 5 to rotate. The belt 5 drives the rotating ring 6 to rotate, and the rotating ring 6 drives the sinking roller 71 to rotate, and the rotating shaft 4 drives the reciprocating screw rod 72 to rotate.

[0039] When the square shell 74 moves, it will come into contact with one end of the sliding rod 751, squeezing the sliding rod 751, so that the sliding rod 751 drives the rotating bar 753 to move. The rotating bar 753 drives the lifting block 754 to move vertically downward along the inner setting of the fixed shell 2, and the lifting block 754 drives the connecting rod 755 to descend. The connecting rod 755 drives the extrusion plate 757 to descend. During the extrusion plate 757 descending, it will come into contact with the top of the fixed plate 761, causing the fixed plate 761 to descend. The fixed plate 761 drives the vertical rod 762 to move downward, and the vertical rod 762 drives the lifting plate 763 to move downward, so that the turning shell 765 in the turning assembly 76 no longer contacts the outer wall bottom of the sinking roller 71. At the same time, the lifting plate 763 is pressed downward, so that the coolant inside the square shell 74 enters the inside of the round tube 771 through the round hole 772, and the coolant enters the inside of the conversion shell 773 through the round tube 771. The coolant enters the inside of the elastic tube 774 through the conversion shell 773, and the coolant enters the turning shell 765 through the elastic tube 774. The interior of the shell 765 performs a cold transfer movement on the turning shell 765, so that the turning shell 765 can perform a cooling movement, preventing the turning shell 765 from being in the deburring work process for a long time on the sinking roller 71, generating heat accumulation, and improving the cleaning effect of the turning shell 765 on the sinking roller 71. When the square shell 74 is no longer in contact with the sliding rod 751, it is elastically deformed by the return spring 766, and the return spring 766 drives the lifting plate 763 to move upward. At this time, the coolant inside the turning shell 765 will enter the interior of the elastic tube 774, and the coolant will enter the interior of the elastic tube 774. The cooling liquid enters the interior of the conversion shell 773 through the elastic tube 774, the cooling liquid enters the interior of the circular tube 771 through the conversion shell 773, and the cooling oil enters the interior of the square shell 74 through the circular hole 772 at the circular tube 771. Due to the setting of the condenser 775, the condenser 775 cools the cooled cooling liquid again, which makes it convenient for the cooling liquid to continue to cool the interior of the turning shell 765, thereby improving the protective effect of the device on the turning shell 765 and indirectly improving the stability of the turning operation of the turning shell 765 on the sinking roller 71.

[0040] When the lifting plate 763 descends, the lifting plate 763 squeezes the rotating plate 781, and is limited by the slide groove 783. The rotating plate 781 drives the slider 782 to slide along the inner wall of the slide groove 783, and the slider 782 drives the cross bar 784 to move, and the cross bar 784 drives the square rod 785 to move, and the square rod 785 drives the arc shell 786 to move, and the arc shell 786 drives the square block 788 to move, and the square block 788 drives the arc cleaning block 789 to move. The two arc cleaning blocks 789 approach each other, so that they can come into contact with the top of the turning shell 765 during the descending process, and scrape and clean the residual debris on the top of the turning shell 765 to prevent the residual debris from staying on the top of the turning shell 765 and affecting the deburring work of the turning shell 765 on the sinking roller 71 When the turning shell 765 is stuck during the contact process, the arc cleaning block 789 is tilted on one side, and the arc cleaning block 789 drives the block 788 to move upward. The block 788 moves upward along the inner wall of the arc shell 786, thereby improving the cleaning effect of the arc cleaning block 789 on the turning shell 765. When the turning shell 765 and the arc cleaning block 789 are not in contact, the extrusion spring 787 elastically deforms and drives the block 788 to move downward. The block 788 drives the arc cleaning block 789 to vertically descend along the inner wall of the arc shell 786, thereby fitting closely with the top of the turning shell 765, thereby improving the cleaning effect of the arc cleaning block 789 on the turning shell 765, and improving the turning effect of the turning shell 765 on the sinking roller 71 from the side.
