Double-head cylinder wheel pair press fit machine with following trolley

Abstract

The invention discloses a double-head cylinder wheel pair press fit machine with a following trolley, which comprises a base, fixed beam devices, a movable beam device, struts, a material carrying trolley, primary pressing oil cylinders, a hydraulic system, an electric control system and a detection device; ejecting pin devices are arranged on the front of the primary pressing oil cylinders; the two fixed beam devices are fixed on the left and right ends of the base respectively and connected with the two cross struts up and down to form a stressed gantry frame; both the left and right fixed beam devices have a primary pressing oil cylinder; the movable beam device is arranged in the machine frame; the movable beam device has two insertion plates; the U-shaped opening of the movable beam and the insertion plates are staged; a positioning pin mechanism is arranged on the movable beam device; the cross section of the two struts is rectangular; round positioning holes are arranged on thestrut bodies at equal distance and matched with the positioning pins on the movable beam; and a following trolley is arranged in the machine frame. The machine is complete in structure and function and can complete various actions including press fit, retracting and detaching and various tests.

Description

technical field [0001] The invention relates to equipment machinery for railway locomotives, in particular to a double-head oil cylinder press-fitting machine with a trolley. It is suitable for wheels, axles and brakes of locomotives with different gauges such as domestic and foreign meter gauge, standard gauge and wide gauge, urban rail transit (subway, light rail), passenger cars with 2 to 3 brake discs, and ordinary freight cars. Disc, gear, reduction box assembly, pressure inspection or extrusion test and disassembly, back pressure test. Background technique [0002] As the train speeds up for many times, the design of the wheel and wheel sets is constantly updated. From the previous without brake discs to the appearance of wheels with 2 or 3 brake discs to meet the needs of high-speed operation for smooth, safe and reliable operation, the The original axle press-fitting machines of wheel factories, vehicle factories or locomotive depots are no longer suitable for the d...

Problems solved by technology

For this reason, existing manufacturers have researched and developed professional press-fitting machines and unloading machines. Although this single-function machine can meet the needs of the market, press-fitting and unloading are just two opposite action processes. The parts are basically the same, so resources are wasted and the cost of using manufacturers is increased
