After attaching, the air pump 49 is operated to pump the compressed air into the flow channel 45 through the pipeline and the air supply joint 44, and through the flow channel 45 The pump is pumped into the annular groove 46, so that the multiple rubber rings 42 are closely fitted with the circular cutter and the sintering disk respectively to prevent gaps from being generated at the contact position, thereby improving the vacuum degree inside the adsorption cylinder 41 and ensuring the adsorption stability of the circular cutter and the sintering disk. After the adsorption is completed, the piston rod of the hydraulic cylinder is shortened to drive the bracket 3 to move upward, driving the circular cutter and the sintering disk to move upward, and then the servo motor in the driving mechanism 2 drives the lead screw to rotate, and the lead screw drives the internal thread block to move to the left along the inner wall of the track, so that the hydraulic cylinder, the bracket 3 and the adsorbed circular cutter and sintering disk move to the left, After the annular cutter and sintering disk are moved to the top of the sintering disk storage area, the hydraulic cylinder drives the annular cutter and sintering disk to move downward through the bracket 3, and the sintering disk is placed in the storage area of the sintering disk. Then, the vacuum pump is used to release the negative pressure in the adsorption cylinder 41 for adsorbing and positioning the sintering disk, thereby releasing the adsorption and positioning of the sintering disk.

[0034] like Figure 3As shown, in this embodiment, the flow channel 45 includes an annular cavity 451 opened inside the cylinder wall of the adsorption cylinder 41, the annular cavity 451 is connected with the air supply connector 44, a vertical groove 452 is opened at the bottom of the annular cavity 451, the vertical groove 452 is used for connecting the annular cavity 451 with the annular groove 46, the number of vertical grooves 452 in the same annular cavity 451 is six, and the six vertical grooves 452 are distributed in a circular array with the center of the annular cavity 451 as the array center, the air pump 49 is operated to generate compressed air, the compressed air enters the annular cavity 451 through the pipeline and the air supply connector 44, and then enters the annular groove 46 through the vertical groove 452, so that the rubber ring 42 expands.
[0035] like Figure 3 As shown, in this embodiment, the bottom of the inner wall of the annular cavity 451 is a downward curved surface, which is used to guide the compressed air so that the compressed air automatically flows into the vertical groove 452 at the bottom of the inner wall of the annular cavity 451 under the action of the curved surface.
[0036] like Figure 3 As shown, in this embodiment, the top of the inner wall of the vertical groove 452 is in the shape of a trumpet with an opening facing upward. The trumpet-shaped shape can increase the amount of compressed air entering the vertical groove 452, thereby causing the rubber ring 42 to expand rapidly.
[0037] like Figure 3 As shown, in this embodiment, a guide ring 5 is fixed to the top of the inner wall of the annular cavity 451 , and the guide ring 5 is used to guide the compressed air entering the annular cavity 451 , effectively preventing the compressed air from accumulating at the top of the inner wall of the annular cavity 451 .

[0039] like Figure 3 As shown, in this embodiment, the inclination angle of the guide surface is forty-five degrees. The forty-five-degree guide surface is used to achieve stable guidance of the airflow as it flows through. Under the action of the forty-five-degree guide surface, the airflow flows smoothly to the bottom position of the inner wall of the annular cavity 451.
[0040] like Figure 3 As shown, in this embodiment, an inner ring 47 and an outer ring 48 are fixed on both sides of the inner wall of the annular groove 46, and the inner ring 47 is located inside the outer ring 48. The inner ring 47 and the outer ring 48 are both made of metal and have a high hardness, so that the rubber ring 42 can only expand from the bottom of the rubber ring 42 when expanding, so that the rubber ring 42 and the circular cutter or sintering disk fit more closely.
[0041] like Figure 3As shown, in this embodiment, the central axes of the annular groove 46, the inner ring 47 and the outer ring 48 are all coincident with the central axis of the rubber ring 42, ensuring that the annular groove 46, the inner ring 47 and the outer ring 48 are concentric with the rubber ring 42. When the compressed air enters the annular groove 46, the bottom of the inner wall of the annular groove 46 is evenly stressed, so that the expansion of the bottom of the rubber ring 42 corresponding to the annular groove 46 is more uniform.
[0042] like Figure 3 As shown, in this embodiment, the outer wall of the inner ring 47 and the inner wall of the outer ring 48 are both inclined surfaces, and the distance between the top of the inner ring 47 and the top of the outer ring 48 is smaller than the distance between the bottom of the inner ring 47 and the bottom of the outer ring 48, thereby increasing the expansion area of the bottom of the inner wall of the annular groove 46, thereby increasing the contact area between the rubber ring 42 and the circular cutter or sintering disk, thereby improving the vacuum degree inside the adsorption cylinder 41.
[0043] Working principle: The piston rod of the hydraulic cylinder of the driving mechanism 2 is extended to drive the bracket 3 to move downward, and the bracket 3 drives the adsorption cylinder 41 and the rubber ring 42 to move downward, so that the multiple rubber rings 42 are respectively fitted with the circular cutter and the top of the sintering disk. The air pump 49 operates to pump the compressed air into the flow channel 45 through the air supply joint 44, and then pumps it into the annular groove 46 through the flow channel 45. Under the action of the inner ring 47 and the outer ring 48, the bottom of the rubber ring 42 expands, so that the multiple rubber rings 42 are respectively tightly fitted with the circular cutter and the sintering disk to prevent gaps from being generated at the contact position, thereby improving the vacuum degree inside the adsorption cylinder 41 and ensuring the adsorption stability of the circular cutter and the sintering disk;
[0044] After the adsorption is completed, the piston rod of the hydraulic cylinder is shortened to drive the bracket 3 to move upward, driving the annular cutter and the sintering disk to move upward, and then the servo motor in the driving mechanism 2 drives the lead screw to rotate, and the lead screw drives the internal thread block to move to the left along the inner wall of the track, so that the hydraulic cylinder, the bracket 3 and the adsorbed annular cutter and the sintering disk move to the left. After the annular cutter and the sintering disk are moved to the top of the sintering disk storage area, the hydraulic cylinder drives the annular cutter and the sintering disk to move downward through the bracket 3, and the sintering disk is placed in the storage area of the sintering disk, and then the vacuum pump is used to release the negative pressure state in the adsorption cylinder 41 that adsorbs and positions the sintering disk, thereby releasing the The sintering disk is adsorbed and positioned, and then the annular cutter is moved to the storage area of the annular cutter, and the negative pressure state in the adsorption cylinder 41 for adsorbing and positioning the annular cutter is released, so that the annular cutter is placed in the annular cutter storage area, thereby realizing the release of the sintering disk. After the annular cutter on the sintering disk is removed from the sintering disk, the sintering disk placed in the storage area can be used to store the compressed annular cutter again for subsequent sintering processing. After releasing the adsorption and positioning of the annular cutter and the sintering disk, the solenoid valve connected to the air pump 49 and the air supply interface is opened to discharge the compressed air to restore the rubber ring 42 to its original state.
