[0040] The working principle and beneficial effects of the above solution:

[0041] In this application, the harrow disc is fixed by the clamping rod 30 and the pressing rod 38. The clamping rod 30 limits the side of the harrow disc, and the pressing rod 38 presses on the upper surface of the harrow disc, pressing the harrow disc on the processing table 1 to rigidly fix the harrow disc. After being firmly fixed, the unprocessed parts of the harrow disc exposed between each group of clamping rods 30 and between each group of pressing rods 38 are processed by the laser gun, and are quickly cooled after processing. After cooling, the fixation of the clamping assembly 2 is cancelled, which can effectively avoid the deformation of the harrow disc caused by laser processing of the harrow disc.

[0042] Embodiment 2

[0043] Please refer to Figures 4 - 8, on the basis of Embodiment 1, the clamping assembly 2 includes a fixing plate 25, the fixing plate 25 is fixedly connected to the processing table 1, a rotating ring 26 is rotatably connected to the fixing plate 25, a sleeve ring 28 is rotatably connected to the rotating ring 26, a clamping arm 27 is slidably connected inside the sleeve ring 28, and one end of the clamping arm 27 is rotatably connected to the fixing plate 25, and the other end of the clamping arm 27 is connected to a clamping rod 30.

[0044] The clamping arm 27 is arc-shaped, and the clamping arm 27 deflects towards the center of the fixing plate 25.

[0045] A driving plate 31 is fixedly connected to the rotating ring 26, a driving rotating block 32 is rotatably connected to the driving plate 31, a driving rod 33 is threadedly engaged with the center of the driving rotating block 32, the driving rod 33 passes through a connecting block 34 and is fixedly connected to a motor 35, the motor 35 is fixedly connected to the connecting block 34, the driving rod 33 is rotatably connected to the connecting block 34, and the connecting block 34 is rotatably connected to the fixing plate 25.

[0046] A slider 36 is slidably connected inside the end of the clamping arm 27, a compression spring is arranged between the slider 36 and the front end of the clamping arm 27, and a clamping rod 30 is slidably connected inside the slider 36;

[0047] A sliding groove 29 is arranged on the clamping arm 27, and the clamping rod 30 is slidably connected inside the sliding groove 29.

[0048] A threaded sleeve 37 is rotatably connected inside the slider 36, the threaded sleeve 37 is threadedly engaged with the clamping rod 30, the threaded sleeve 37 is engaged with a gear 39, the gear 39 is rotatably connected to the slider 36, and a part of the gear 39 is exposed outside the upper surface of the slider 36, and the gear 39 is engaged with a rack arranged on the inner surface of the clamping arm 27;

[0049] The upper end of the clamping rod 30 is fixedly connected with a pressing rod 38, there are several groups of pressing rods 38, and the pressing rods 38 are diverging.

[0050] The working principle and beneficial effects of the above solution:

[0051] When fixing the harrow disc, start the motor 35, drive the driving rod 33 to rotate, so that the distance between the driving rotating block 32 and the connecting block 34 is shortened, make the rotating ring 26 rotate relative to the fixing plate 25, and then drive the clamping arm 27 to deflect, the end approaches the center of the rotating ring 26. After the clamping rod 30 connected to the clamping arm 27 contacts the side of the harrow disc, the clamping arm 27 continues to deflect, the clamping rod 30 drives the slider 36 to squeeze the compression spring and slide into the clamping arm 27, the gear 39 connected to the slider 36 and the rack on the clamping arm 27 are displaced relative to each other, make the gear 39 rotate, and then drive the threaded sleeve 37 to rotate, the rotation of the threaded sleeve 37 makes the clamping rod 30 slide downwards, and the pressing rod 38 fixed to the upper end of the clamping rod 30 presses against the upper surface of the harrow disc;

[0052] By fixing the side and upper surface of the harrow disc, the movement of the harrow disc in all directions is restricted. When laser processing is carried out and the harrow disc expands due to heat or contracts during subsequent cooling, due to the restriction of the side clamping rod 30, the upper surface crimping rod 38, and the lower surface processing table 1, it can ensure to the greatest extent that the harrow disc still maintains the size before treatment in all directions, effectively preventing the deformation of the harrow disc;

[0053] Moreover, this component can restrict the harrow disc in all directions with only one drive. While ensuring the fixing effect, it simplifies the structure and has high practicality.

[0054] Embodiment 3

[0055] Please refer to Figures 1 - 3 , on the basis of Embodiment 1, the transfer component 10 includes a housing 11. A limiting sleeve 17 is fixedly connected inside the housing 11. A plugging block 13 is slidably connected to the inner wall of the limiting sleeve 17. An inner housing 12 is fixedly connected to the lower side of the plugging block 13. The inner housing 12 is located inside the housing 11. A through hole 14 is provided at the center of the plugging block 13. A first sealing plug 15 is provided at the upper end of the through hole 14. The first sealing plug 15 is slidably connected to the housing 11;

[0056] A first spring 16 is provided between the first sealing plug 15 and the housing 11. The first spring 16 is sleeved on the first sealing plug 15. The two ends of the first spring 16 are respectively fixedly connected to the inner wall of the housing 11 and the lower part of the first sealing plug 15;

[0057] A vacuum pump is connected to the housing 11 on the outside of the first sealing plug 15;

[0058] A second spring 19 is sleeved on the outer periphery of the limiting sleeve 17. The two ends of the second spring 19 are respectively fixedly connected to the inner wall of the housing 11 and the pressure platform 21 in the middle of the inner housing 12.

[0059] A bottom plate 23 is provided at the lower end of the inner housing 12. An opening 24 is provided on the bottom plate 23. A trigger frame 18 is provided on the pressure platform 21 in the middle of the inner housing 12. A trigger rod 22 is provided at the upper end of the trigger frame 18;

[0060] A second sealing plug 20 is provided on the housing 11. The second sealing plug 20 is slidably connected to the housing 11. The second sealing plug 20 is provided above the trigger rod 22.

[0061] The elastic force of the first spring 16 is greater than the elastic force of the second spring 19.

[0062] The working principle and beneficial effects of the above solution:

[0063] The vacuum pump evacuates the inside of the outer shell 11. The air between the outer shell 11 and the rake blades is discharged from the through hole 14. After the suction stops, under the action of the first spring 16, the first sealing plug 15 blocks the through hole 14. The suction of the vacuum pump reduces the air between the outer shell 11 and the rake blades, and the pressure is less than the external atmospheric pressure, causing the rake blades to adsorb on the outer shell 11. When the pressure between the outer shell 11 and the rake blades decreases to a certain extent, it will cause elastic deformation of the rake blades. When the pressure continues to decrease, it will cause plastic deformation of the rake blades. To ensure the structure of the rake blades and avoid deformation of the rake blades, after the rake blades undergo elastic deformation, the rake blades will squeeze the inner shell 12, overcoming the elastic forces of the first spring 16 and the second spring 19 to move the inner shell 12 upward, so that the trigger rod 22 pushes up the second sealing plug 20, and air enters the outer shell 11 from the second sealing plug 20, increasing the pressure inside the outer shell 11, avoiding plastic deformation of the rake blades, and ensuring the structure of the rake blades;

[0064] The pressure inside the outer shell 11 is dynamically adjusted by the sliding of the inner shell 12, which can transfer the rake blades while avoiding deformation of the rake blades.
