Automatic press fitting rapid conversion device and method for railway wagon wheel pairs

Abstract

The invention relates to an automatic press fitting rapid converting device and a method for railway wagon wheel pairs. The device comprises a trolley track and bracket trolleys which can move back and forth on the trolley track, and a fixed lifting bracket assembly is arranged above the trolley rail and is positioned below a press fitting assembly for pressing the to-be-pressed wheel pairs, so that the railway wagon wheel pairs can be lifted to the press fitting assembly to carry out press-fitting for the to-be-pressed wheel pairs. According to the automatic press fitting rapid converting device and the method for the railway wagon wheel pairs, fixed lifting brackets are additionally arranged in the middle of an automatic press fitting unit of original wheel pairs, exchange of the two-bracket moving trolleys to the to-be-pressed wheel pairs is completed through the fixed lifting brackets, and the operation distance of a single trolley is shortened; the same bracket moving trolleys arearranged at the inlet ends and the outlet ends of the fixed lifting brackets correspondingly, the working time of the to-be-to-be-pressed wheel pairs bracket moving trolleys and the working time of the press fitting bracket moving trolleys are set to be the same, and a beat production pattern is formed; the efficiency is improved by one time, and a bottleneck in production is solved; and the device is simple in structure, the production line does not need to be changed greatly, and the production cost is low.

Description

technical field [0001] The invention relates to a device and method for automatic press-fitting and fast switching of wheel pairs, in particular to an automatic press-fitting and fast switching device and method for railway freight wheel sets. Background technique [0002] There are generally two press-fitting methods in the railway freight wheel pair press-fitting process; one is to use a fixed bracket to support the axle, and then manually insert the left and right wheels into the left and right ends of the axle, and then use the Manually hoist the set of wheels to be pressed into the press-fitting machine to complete the press-fitting. This method is backward in technology and often has safety risks. [0003] The second is to use the wheel set automatic pressing unit for automatic pressing. In the wheel set automatic press-fitting unit, the wheel set press-fitting is to select and match the qualified wheels and axles and then input them into the pressing-fitting area of ...

AI Technical Summary

Problems solved by technology

[0005] However, the prior art has the following disadvantages: in the wheel set automatic press-fitting unit, it takes a long time for the carriage to move the trolley from forming the wheel set to be pressed into the press-fitting machine to the press-fitting station. , the production tempo in the entire production line cannot match the tempo of other processes on the line. With the increase of process capacity, this process has become a bottleneck process in the wheel set automatic press-fitting unit, which needs to be solved urgently
