Wheel set dismantlement press-fit machine for rail transit rolling stock

Abstract

The invention discloses a wheel set dismantlement press-fit machine for a rail transit rolling stock. The machine comprises a machine base, a machine frame, a wheel axle positioning telescoping mechanism, a wheel clamping driving mechanism and a wheel clamping mechanism, wherein the machine frame is installed on the machine base, the wheel axle positioning telescoping mechanism is installed on the machine frame to be used for clamping and moving a wheel axle of a wheel set to be subjected to dismantlement press-fitting, the wheel clamping driving mechanism is installed on the machine frame to be used for driving the wheel clamping mechanism to move in the axial direction, and the wheel clamping mechanism is connected with the wheel clamping driving mechanism to be used for clamping wheels of the wheel set to be subjected to dismantlement press-fitting. The machine has the advantages that the structure is simple, operation and use are convenient, dismantlement press-fitting of two wheel sets can be conducted independently or simultaneously, automatic feeding and discharging of wheel sets can be achieved, the labor intensity of workers can be relieved, and wheel set dismantlement time can be shortened; besides, force is applied to a shaft body rather than a shaft end during dismantlement, so that heading and damaging of the shaft end is effectively avoided during dismantlement.

Description

technical field [0001] The invention relates to the technical field of wheel set disassembly, in particular to a rail transit-based disassembly press-fitting machine, in particular to passenger and freight wheel sets. Background technique [0002] At present, the disassembly and pressing equipment for passenger and freight wheel sets produced at home and abroad has a large disassembly process. The end face of the wheel is blocked by a baffle, and the front end face of the piston rod of the pressure head cylinder is in contact with the end face of the axle. The axle moves, the wheel cake does not move, the axle wheel seat is pressed out of the wheel hole, and the wheels can only be disassembled one by one. Among them, the axle material is 50# steel as an example, the extrusion stress of the material is ≯150MPa, and the diameter of the axle end When the front end face of the piston rod is in full contact with the end face of the axle, the axle end can only withstand a pressu...
