the method comprises the following steps: installing slips: placing three slips (43) on a guide plate (12) respectively, and embedding a guide block (45) of the slips (43) into a sliding rail (121) of the guide plate (12); the return springs (44) are placed in cylindrical counter bores on the side edges of the slips (43), and each return spring (44) is ensured to penetrate through the corresponding cylindrical counter bores of two adjacent slips (43);
step two: tightening slips: high-pressure hydraulic oil is introduced into a rod cavity of the tightening oil cylinder (132), a piston rod of the tightening oil cylinder (132) is driven to be recovered, a push-pull disc (131) is driven to move downwards, the push-pull disc (131) drives three tightening pressure plates (11) to move towards the center of a guide plate (12) through three connecting rods (134), so that an arc-shaped plate (111) of the tightening pressure plate (11) pushes a slip (43) to move towards the center of the guide plate (12), and a return spring (44) is compressed at the same time until the slip (43) is tightened until adjacent sides are contacted;
step three: sleeving a rubber cylinder: sleeving a rubber cylinder (42) externally provided with a chuck body (41) outside a slip (43) compressed by a return spring (44), introducing high-pressure hydraulic oil into a rodless cavity of a tightening oil cylinder (132), driving a push-pull disc (131) to move upwards by a piston rod of the tightening oil cylinder (132), and driving a tightening pressure plate (11) to move towards a direction far away from the center of a guide plate (12) through a connecting rod (134), so that the slip (43) is loosened; the resilience force of the return spring (44) props open the adjacent slips (43) for a certain distance until the arc surface of the slips (43) is attached to the inner wall of the rubber cylinder (42);
step four: pressing down the rubber cylinder: rotating the pressing swing arm (21) to be right above the rubber cylinder (42), introducing high-pressure hydraulic oil into a rod cavity of the pressing cylinder (223), driving the sliding sleeve (222) and the pressing swing arm (21) to move downwards by the pressing cylinder (223), and completely sleeving the rubber cylinder (42) externally provided with the chuck body (41) on the slip (43); high-pressure hydraulic oil is introduced into a rodless cavity of the downward pressure oil cylinder (223), the sliding sleeve (222) is driven to ascend to the limit position, the downward pressing swing arm (21) is rotated and moved away, the hydraulic chuck with the slips (43) installed is taken down, and subsequent parts are installed.
