Gearbox multi-degree-of-freedom upender and method

Abstract

The invention discloses a gearbox multi-degree-of-freedom upender and a method. The gearbox multi-degree-of-freedom upender comprises a driving mechanism and a bearing frame, wherein the driving mechanism is used for providing driving force for the bearing frame to rotate in the horizontal direction and driving force for the bearing frame to rotate in the vertical direction; the bearing frame comprises a frame body, a bearing support, a limiting support, a gearbox bracket and a guide bracket; the bearing support is rotationally arranged on the frame body; the limiting support is rotationally arranged on the frame body; the gearbox bracket is rotationally arranged on the frame body; and the guide bracket can support a gear shaft in a horizontal state from bottom to top in the vertical direction or hang the gear shaft in a vertical state in the radial direction of the gear shaft. According to the upender, three stations are integrated and centralized into a whole, so that the steps of back-and-forth adjustment and movement between different procedures and back-and-forth mounting and dismounting of a hoisting clamp in the original operation process are reduced, time for the same is shortened, and the operation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of gear box assembly equipment, and more specifically relates to a gear box multi-degree-of-freedom turning machine and a method. Background technique [0002] The overhaul of the axle gearbox is an important part of the overhaul of the axle, especially in the advanced repair process, the overhaul process is long, involves a lot of content, high technical requirements, and strong correlation factors. For example, the CRH3, 380B and CR400BF EMU advanced gearbox shaft inspection station mainly includes three stations: gearbox assembly, large gear clearance adjustment, and pinion assembly operation. At present, due to the lack of professional tightening system equipment and tooling, the problems in the assembly of gearbox shafts in the advanced repair bogie workshop of the bullet train depot are as follows: [0003] First of all, the maintenance stations are scattered and the efficiency is low. At present, th...

AI Technical Summary

Problems solved by technology

The station layout is relatively scattered, and there is a distance between the stations, which increases the time for the transfer of parts between each station; to complete the overhaul of the gear shaft at these three stations, at least three operators are required The characteristic of human-made operations is that it is prone to fatigue and relies too much on manual operations. When the operators are engaged in a large number of tasks with high repetition, it is easy to have potential safety hazards, and the consumption of time and personnel costs in the operation process is relatively large. big

[0004] Secondly, the operating tools are relatively primitive, labor-intensive, and there are potential safety hazards in hoisting operations

The overhaul of the gear box shaft of the EMU is different from the overhaul of the wheel set. The wheels of the wheel set work can roll on the ground track, so there will be no major safety problems; however, the gearbox shaft itself is relatively heavy (nearly 1 ton) , with large dimensions and irregular shapes. Therefore, according to the previous operation mode, it is often necessary to use cranes to lift workpieces between different processes at the same station or between different stations. The frequent lifting volume Relatively large and heavy workpieces will have potential safety hazards and the risk of workpieces falling, both in terms of perception and actual operation scenarios.
