High-precision wheel pair positioning and transferring mechanism for railway vehicle production

Abstract

The invention relates to the technical field of railway production equipment, in particular to a high-precision wheel pair positioning and transferring mechanism for railway vehicle production. Linearmoving devices, synchronous devices and wheel pair positioning devices are included. Each wheel pair positioning device comprises a moving mechanism, a buffering mechanism and a shaft positioning mechanism. A wheel pair is placed on an iron rail. The shaft positioning mechanisms are arranged on the two sides of the wheel pair and are connected with a rotation shaft of the wheel pair in a clampedmanner. The buffering mechanisms are arranged below the shaft positioning mechanisms. The work direction of the buffering mechanisms is the same with the wheel pair transportation direction. The moving mechanisms are arranged below the buffering mechanisms and drive the buffering mechanisms to move towards the wheel pair from the two sides of the wheel pair. The synchronous devices and the movingmechanisms are arranged on the linear moving devices. The linear moving devices are arranged on the two sides of the iron rail. The transportation direction of the linear moving devices is the same with the wheel pair transportation direction. The mechanism does not need a high-precision rack, safety synchronous mechanisms are arranged on the linear moving devices of the mechanism, the wheel pairis not prone to derailing during transportation, and rack damage is not likely to happen.

Description

technical field [0001] The invention relates to the technical field of railway production equipment, in particular to a high-precision wheelset positioning and transfer mechanism for railway vehicle production. Background technique [0002] The safety of railway transportation is related to the national economy and the people's livelihood, and railway wheelsets are directly related to the safety of railway transportation. In the production and maintenance process of railway vehicles, there are many working procedures on railway wheel sets, and the professional equipment is various. How to effectively and effectively position the wheel sets is related to the quality of various operations on the wheel sets, especially in wheel sets. How to accurately, safely and smoothly move to the next operation process on the production and assembly line of the equipment and its related accessories has become a problem that many companies that provide non-standard equipment for railways are...

AI Technical Summary

Problems solved by technology

[0005] 1. Two sets of sliding bases that work synchronously are used. Once one set fails and stops immediately, the other set will continue to move forward, which will cause the wheelset to fly out of the positioning horizontal moving seat, which is very dangerous;

[0006] 2. If the positioning wheel is too far away, the wheel set can roll for a long distance on the positioning horizontal moving seat. When the positioning horizontal moving seat stops moving, the wheel set will continue to roll under the action of inertia, and then hit the positioning wheel. The rack is damaged and the service life is low;

[0007] 3. There is no corresponding protection mechanism for the problem that the wheelset may be deflected and derailed during the process of sliding on the track
