Abstract

The invention discloses a wheel axle assembly process method. The wheel axle assembly process method comprises the step of conducting assembling by using an integrated wheel axle assembly line. The integrated wheel axle assembly line comprises a U-shaped conveying channel used for conveying wheel pairs, and dustproof check ring assembly equipment, bearing inner ring assembly equipment, a bearing axle box assembly machine, gland assembly equipment and axle box cover assembly equipment are sequentially arranged on the U-shaped conveying channel. The U-shaped conveying channel is provided with a grease injection machine on one side of the bearing axle box assembling machine, all the pieces of equipment are connected with a control unit, and the bearing axle box assembly machine and the grease injection machine are synchronous in the wheel axle processing quantity. According to the wheel axle assembly process method, the problems that the assembly precision cannot be guaranteed and the organization efficiency is low due to the fact that an existing passenger train wheel axle is assembled loosely can be solved.

Description

technical field [0001] The invention relates to the technical field of manufacturing railway passenger cars, in particular to an axle assembly process for railway passenger cars. Background technique [0002] According to the service life and mileage of the vehicle, the wheel axle repair program is divided into section repair and factory repair. Different repair programs have different technical standards for passenger cars with different speed levels, and the process methods and processes used are also different. At present, the assembly of wheel shafts in China is mostly an integrated operation, that is, a single assembly process is formed after the pre-process parts are prepared at a fixed station. The assembly process generally includes: assembling the dust-proof retaining ring and the inner ring of the bearing, and placing the bearing shaft Box, bearing axle box assembly, gland assembly, axle box cover assembly; use the dust-proof retaining ring assembly equipment, bear...
