Problems solved by technology
In this way, after the wheel set on the production line track is moved into the bearing press machine, it is more difficult to align the center of the wheel set with the press center
In actual operation, hoisting tools such as cranes are generally used to adjust the position of the center of the wheel set, and then move it into the bearing press machine for bearing press installation, which is time-consuming and laborious.

Embodiment Construction
[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0020] Such as Figure 1~3 As shown, the railway wheel set bearing press-fitting and centering device of the present invention includes two support rails 2 arranged laterally between the bearing press-fitting machine 1 and the production line track 3, and the support rails 2 are equipped with a mobile platform 4 slidingly matched thereto , the mobile platform 4 is longitudinally provided with a platform fixing rail 5 and a platform adjusting rail 6, and one side of the mobile platform 4 is connected with a platform driving device 7. The platform driving device 7 can be one of a hydraulic oil cylinder, a wind-driven cylinder or an electric drive device, and the wind-driven cylinder is selected in this embodiment. The two support rails 2 are symmetrically provided with stopper chute 2a, and a limit stopper 8 slidingly matched with it i...

The invention discloses a method and a device for press-mounting and centering of variable-gauge railway wheel set bearings. The method includes that a transversely slidable moving platform is arranged between a bearing press-mounting machine and a production line rail for a variable-gauge wheel set, the variable-gauge wheel set is firstly pushed onto a platform fixing rail and a platform adjusting rail from the production line rail, transverse displacement of the moving platform is integrally adjusted so that the gauge center line of the moving platform is aligned to the press-mounting center line of the bearing press-mounting machine, and finally the variable-gauge wheel set is pushed into the bearing press-mounting machine. The device comprises the moving platform transversely arranged between the bearing press-mounting machine and the production line rail, one side of the moving platform is connected with a platform driving device, a stopper sliding groove is arranged on a support rail, a limit stopper in sliding fit with the stopper sliding groove is arranged in the stopper sliding groove and can be abutted to the moving platform. By the aid of the method and the device, the gauge center of the variable-gauge wheel set and the press-mounting center of the bearing press-mounting machine can be accurately aligned, and surface injury of workpieces is avoided.
Description
technical field [0001] The invention relates to the assembly technology of railway vehicle axles, in particular to a press-fitting and centering method and device for railway track gauge wheel set bearings. Background technique [0002] In the railway wheel-rail structure at home and abroad, there are many types of wheel sets with different gauges, such as meter-gauge or narrow-gauge wheel sets in Southeast Asia and Africa, standard-gauge wheel sets in China, Europe and the United States, and India and other countries wide gauge wheelsets. In the assembly process of railway axles, the rolling bearing press-fitting at both ends of wheelsets with different gauges is one of the most important links in the whole process. [0003] At present, the center of the bearing press machine used for railway wheel sets is designed according to the center of the standard gauge. In the production process of railway wheelsets, in order to realize the press-fitting of rolling bearings at bot...
