High-precision wheel set 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 set positioning and transferring mechanism for railway vehicle production. The high-precision wheel set positioning and transferring mechanism comprises linear moving devices, a synchronous device and a wheel set positioning device, wherein the wheel set positioning device comprises a movable mechanism, a buffer mechanism and shaft positioning mechanisms, wherein a wheel set is arranged on a rail, the shaft positioning mechanisms are arranged on the two sides of the wheel set and are arranged with a rotating shaft of the wheel set in a clamped mode, the buffer mechanism is installed below the shaft positioning mechanisms, the working direction of the buffer mechanism is thesame as the conveying direction of the wheel set, the movable mechanism is installed below the buffer mechanism and drives the buffer mechanism to move towards the wheel set from the two sides of thewheel set, the synchronous device and the movable mechanism are both installed on the linear moving devices, the linear moving devices are arranged on the two sides of the rail, and the conveying direction of the linear moving devices is the same as the conveying direction of the wheel set. The mechanism does not need a high-precision rack, a safety synchronizing mechanism is installed on the linear moving devices of the mechanism, the wheel set is not prone to derailing during transportation, and the rack is not easy to damage.

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
