Disassembly tool for interference fitting pin using hollow cylinder

摘要

The present invention has a small-sized hollow cylinder part having a hydraulic capacity capable of generating a hydraulic force capable of disassembling a knock pin fastened to the mechanical equipment of a power plant, and the pin is fixed to the cylinder part. The present invention relates to a disassembly tool for an interference fit pin using a hollow cylinder for easily removing a knock pin secured by a knock pin holder.;According to the present invention, the hollow cylinder portion 10 for applying a hydraulic force to remove the fixing pin (95) forcibly fit to the mechanical equipment of the power plant, and the open end of the cylinder portion 10 A hollow piston portion 20 inserted into the spring 13 and coupled to the outer circumference, a ring 40 for limiting movement of the piston portion 20, and a stop 50; In the disassembly tool for the interference fitting pin using a hollow cylinder, the inner circumferential surface of the inner wall 16 of the cylinder portion 10, the fixing pin nut 90 of the fixing pin 95 in the inner space 84 There is provided a disassembly tool for an interference fit pin using a hollow cylinder, characterized in that the fixing pin holder 80 for transmitting the compressive force in the direction in which the fixing pin 95 is removed by mounting.
