[0038] Among them, the inner ring clamping assembly 6 can clamp the inner ring surface of the inertia part, and the outer ring clamping assembly 7 can clamp the outer ring surface of the inertia part. When the inner ring clamping assembly 6 clamps the inner ring surface of the inertia ring, the grinding assembly 2 grinds the end face and the outer ring surface of the inertia part, and then the transfer clamping assembly clamps the inner ring surface of the inertia part and drives the inertia part to the lower part. The outer ring clamping assembly 7 clamps the outer ring surface of the inertia part and rotates the inertia part to the upper part again, so that the grinding assembly 2 can grind the inner ring surface of the inertia part, reducing the number of disassembly times when processing the inner and outer ring surfaces of the inertia part.

A method for processing the surface processing device of the shock absorber inertia ring as claimed in claim 2, characterized in that: The steps include: The inertia ring is placed on the first box body (9), and the driving electric cylinder (23) on one side drives the driving plate (24) to move, and drives the driving shaft (26) to move, so that the third bevel gear (27) is meshed with the first bevel gear (15), and the first motor (25) drives the driving shaft (26) to rotate, thereby driving the first bevel gear (15) to rotate, so that the first protrusion (14) drives a plurality of outer support blocks (11) to move outward synchronously, and clamps the inner ring surface of the inertia ring; The grinding assembly (2) grinds the end face and the outer ring surface of the inertia ring; The third motor (35) drives the second gear (36) to rotate, and the second gear (36) drives the sleeve (33) to rotate through the transmission of the first gear (34), so as to rotate the arc-shaped bracket (8) to a vertically upward state, and the intermediate clamping assembly clamps the inner ring surface of the inertia ring. The third motor (35) is powered off, and the arc-shaped bracket (8) rotates to a vertically downward state under the action of its own weight; When the position of the arc-shaped bracket (8) is stabilized, the pushing electric cylinder (23) on the other side is transmitted to the outer ring clamping assembly (7), so that the outer ring clamping assembly (7) clamps the outer ring surface of the inertia component, and the intermediate clamping assembly releases the clamping of the inner ring surface of the inertia component. The fourth motor (37) drives the transmission shaft (5) to rotate 180 degrees, so that the outer ring clamping assembly (7) rotates to the upper part, and the grinding assembly (2) grinds the inner ring surface of the inertia ring.
