Abstract
The utility model discloses an assembling and disassembling device for a locomotive suspension bearing box inner bearing locating labyrinth ring. The device comprises a workpiece locating and supporting frame fixed to a base and a workbench capable of moving on a base rail, wherein a medium-frequency heater corresponding to the labyrinth ring in shape and size is arranged on the workbench, and a movable hydraulic-drive telescopic bracket and a clamp are arranged on the portion, between the workbench and the workpiece locating and supporting frame, of the base rail. Disassembling and assembling time is saved, work efficiency is improved, labor intensity of workers is relieved, safety of operators is guaranteed, the disassembled labyrinth ring can be reused, material cost is saved, electricity consumption is reduced, and cost for maintaining a locomotive is reduced.
Description
Technical field
The utility model relates to a kind of vehicle axle box inner bearing location labyrinth ring Assembly And Disassembly device, belongs to Machining Technology field.
Background technology
Vehicle axle box inner bearing location labyrinth ring is 0.45mm with the locomotive axle assembling magnitude of interference, heats 2～3 hours to 290 ℃ in therefore labyrinth ring need to being put into powerful heating furnace when assembling, and allows after its thermal expansion and just can complete assembling.Consumption quantity of energy is large, contaminated environment, and workman is dangerous when assembling.On the other hand, in maintenance process, because the assembling magnitude of interference of labyrinth ring is large, and between axle suspension bearing box, space is little, and is not designed with the reason of dismounting oil filler point, makes to dismantle abnormal difficult.The dismounting of labyrinth ring at present can only be lifted on whole drive unit on large-scale lathe, and labyrinth ring is carried out to destructive turning.There is following problem in this way:
1. inefficiency.The labyrinth ring time used of every turning was about about 90 minutes, affected the time between overhauls(TBO).
2. very flexible.Owing to taking main equipment, need expert operator, be not easy to strange land maintenance.
3. unrepairable.Due to labyrinth ring is carried out to destructive turning, labyrinth ring cannot reuse.
4. the waste of cutter.Labyrinth ring material therefor is hard metal, the special carbide chip that consumes during turning.
Utility model content
The purpose of this utility model overcomes the deficiency of above-mentioned prior art exactly, a kind of vehicle axle box inner bearing location labyrinth ring Assembly And Disassembly device is provided, improve Assembly And Disassembly operating efficiency, alleviate labor strength, and the labyrinth ring of dismounting can be reused.
The purpose of this utility model is achieved in that a kind of vehicle axle box inner bearing location labyrinth ring Assembly And Disassembly device, comprise the workpiece positioning supporting frame being fixed on base and the workbench that can move on base track, it is characterized in that on described workbench arranging the intermediate frequency heater corresponding with the shape of labyrinth ring and size, movably hydraulically powered telescoping bracket and fixture of setting on the base track between described workbench and workpiece positioning supporting frame.
Scheme saving dismounting of the present utility model, installation time, improved operating efficiency, alleviated labor strength, ensured operator's safety, and the labyrinth ring of dismounting can be reused, save fee of material year and reduce power consumption, having reduced the cost of locomotive under repairing.

Assembling process:
1. gear axle suspension bearing box first will be installed to be placed on positioning supporting frame 2;
2. bracket 6 rises, and labyrinth ring 4 is hung on bracket 6;
3. travelling table 3 is contained in labyrinth ring 4 in intermediate frequency heater 5;
4. energising heating is after 8～10 minutes, and labyrinth ring 4 reaches 290 ℃ of temperature and produces thermal expansion;
5. fixture 8 is clamped labyrinth ring 4, and bracket 6 falls;
6. movable clamp 8, and labyrinth ring is delivered to installation site;
7. fixture 8 unclamps, and returns original position;
8. labyrinth ring 4 cooling downs, assembly work finishes.
Unloading process:
1. first the gear axle suspension bearing box that labyrinth ring is installed is placed on positioning supporting frame 2;
2. travelling table 3 is contained in labyrinth ring 4 in intermediate frequency heater 5;
3. energising heating is after 8～10 minutes, and labyrinth ring 4 reaches 290 ℃ of temperature and produces thermal expansion;
4. travelling table exits;
5. movable clamp 8, near labyrinth ring 4 positions, is clamped labyrinth ring 4;
6. reverse movable clamp, pulls down labyrinth ring 4;
7. bracket 6 rises, mobile near fixture, and labyrinth ring 4 is held;
8. fixture 8 unclamps backed off after random, labyrinth ring 4 cooling downs, and dismantlement work finishes.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
