6. The automatic assembly machine for turbocharger shaft seal and piston ring according to claim 1, characterized in that: The pressure ring assembly (51) further includes two reinforcing ribs (518), which are arranged between the connecting plate (520) and the push rod cylinder mounting plate (517).

7. A method for operating an automatic assembly machine for a turbocharger shaft seal and piston ring, using the automatic assembly machine for a turbocharger shaft seal and piston ring according to any one of claims 1 to 6, characterized in that: The specific steps are as follows: (S1) Material preparation: the shaft seal discharging mechanism (1) and the sealing ring discharging mechanism (2) are both filled with material; (S2) The shaft seal discharging mechanism (1) is activated: the two limiting cylinders (13) remain in the extended state, the cutting cylinder (15) is activated, and the shaft seal is cut into the shaft seal limiting member (32) through the pushing member 1 (10). Under the action of the transverse cylinder (31), the shaft seal is brought into the assembly position, and then the shaft seal positioning mechanism (4) is activated; (S3) The assembly mechanism (5) operates as follows: (1) The pressing ring cylinder (56) is activated, the pressing ring assembly (51) is moved to the pressing ring position, and the push rod cylinder (511) is activated, pushing the cone sleeve (516) into the shaft seal product through the push rod (514); (2) The push rod cylinder (511) contracts, the pressure ring cylinder (56) rises, and the sealing ring discharge mechanism (2) moves and resets; (3) At this time, the sealing ring has been installed on the cone sleeve (516), and the pressure ring cylinder (56) lowers the pressure ring assembly (51), and the sealing ring is pressed into the shaft seal under the guidance of the cone sleeve (516) through the expansion sleeve (515). At the same time, the expansion sleeve (515) is compressed under the action of elasticity, and the cone sleeve (516) is retracted inside. The pressure ring cylinder (56) is reset, and the left and right position switching cylinder (58) switches positions. The above actions are repeated to complete the pressing of the two piston rings into the shaft seal; the shaft seal positioning mechanism (4) is reset; (S4) The unloading mechanism (6) operates: the jaw lifting cylinder (62) operates to lift the forward cylinder mounting plate (63), the jaw forward cylinder (64), the jaw member (65), and the jaw (66). Then the jaw forward cylinder (64) operates to drive the jaw member (65) and the jaw (66) to move forward. The jaw member (65) uses the jaw cylinder (69) to enable the jaw (66) to clamp the product. The jaw forward cylinder (64) resets, the jaw lifting cylinder (62) resets, and the jaw cylinder (69) resets. The product slides out through the slide (67). The full material sensor (68) detects whether the material is full, completing the entire operation.
