Bogie assembling and completing technology and swing bolster side frame assembling machine

Abstract

The invention discloses a bogie assembling and completing technology and a swing bolster side frame assembling machine. The swing bolster side frame assembling machine comprises a base, a walking assembly, a lifting assembly, a displacing assembly and a supporting base. The walking assembly comprises two walking tracks fixed to the base and a rack fixedly installed between the two walking tracks.First sliding blocks which are in sliding fit with the walking tracks are arranged on the walking tracks, a first base plate is fixedly arranged at the tops of the first sliding blocks, a walking motor is fixedly installed at one end of the first base plate, and a gear meshed with the rack is fixedly installed on a spindle of the walking motor. By adopting 'one-stop' station logistics, assemblingand completing of each bogie on an assembly line can be achieved just by one-time suspension of a suspension type mechanical hand, the bogies are conveyed to the destination from the starting point ofthe assembly line, the phenomenon that bogies are suspended frequently at all stations is avoided, and the production efficiency is improved.

Description

Technical field [0001] The invention relates to a bogie assembly completion process and a bolster side frame assembly machine, belonging to the technical field of bogie assembly. Background technique [0002] Bogie assembly mainly includes bolster and side frame assembly, cross bar assembly, brake beam assembly, positive detection, installation of saddles, installation of springs and wedges, installation of side bearings, cross beam assembly, assembly of basic brake parts, and steering The frame is completed and other stations. As a key product for carrying railway passenger car boxes running on rails at high speeds, bogies have a direct impact on the safety of the entire train of vehicles. As a relatively independent and complete product in the vehicle composition, the assembly efficiency of the bogie directly determines its ownership The overall delivery plan of the vehicle contract. [0003] At present, the bogie assembly adopts a fixed platform assembly process, which has the...

AI Technical Summary

Problems solved by technology

[0004] 1. Each station on the production line is equipped with a dedicated or shared crane. Each time it is hung, it can only complete the work of this station. Each station needs to be hung repeatedly. Frequent hangings reduce work efficiency. Low;

[0005] 2. Attitude adjustment cannot be realized at the workstation or it needs to be adjusted manually, which is inconvenient to operate and low in efficiency;

[0006] 3. Once the number and location of stations on the production line are determined, it is difficult to change them, and hardware equipment needs to be adjusted to achieve them;

[0007] 4. The production line occupies a large area, the limited workshop area is not fully utilized, and the production efficiency is low;

[0008] 5. Each bogie consists of 1 piece of bolster and 2 pieces of side frame, which can only be assembled one by one during assembly. The lifting equipment is frequently used, the labor intensity is high, and the production efficiency is low. The assembly requires multiple lifting and transportation, which is difficult to achieve Flow production

[0009] To sum up, the existing assembly process cannot effectively guarantee the bogie assembly quality and production efficiency, therefore, it is urgent to develop an advanced bogie assembly process
