Abstract
The utility model discloses a special miller for double arch surfaces of flat coupler yoke keys used in railway vehicles. The miller includes a main body, a vertical power head, a slideway guide rail, a hydraulic slideway traveling mechanism, a working slideway, a special hydraulic clamp for parts, a hydraulic vertical power head traveling mechanism, a hydraulic vertical power head locking mechanism, a main shaft transmission mechanism, a hydraulic power control system and an operation station. Two vertical power heads are used in the utility model to realize simultaneous milling of the two arch surfaces. A hydraulic clamp is used as the part clamp, the part positioning is reliable, and operations are convenient. When the power head is used to mill the part, the hydraulic locking device is used to tightly lock the head to reduce milling vibration, improve service life of the milling blade and improve fabricating efficiency and quality. The utility model is presently an ideal device for each vehicle section/plant of the whole bureau to machine flat coupler yoke keys, and has a wide foreground.
Description
Technical field
The utility model is a kind of mechanical processing machine, is to use in processing, repairs the special machine processing milling machine of railway visitor, the two cambered surfaces of truck vehicle coupler yoke key.
Background technology
The railway visitor, the coupler yoke key of truck vehicle is the critical piece that connects tractor-trailer train, in train travelling process, can cause very big wearing and tearing, journey is repaiied according to maintenance technology in the wearing and tearing back, requirement will be carried out built-up welding to the fray of coupler yoke key, with machining apparatus coupler yoke key is processed into original shape again after the built-up welding, the processing method of at present existing coupler yoke key, what adopt is with planer or manually use pneumatic grinder after the built-up welding, the electric wheel polishing, coupler yoke key with planer processing is of low quality, efficient is low, the artificial pneumatic grinder of using, it is not high that electric wheel also exists crudy simultaneously, efficient is low, the time of workpiece processing is longer, labour intensity to workpiece processing personnel is also big, because of each the in addition part crudy requirement constantly raising of railroad train speed-raising to vehicle, above processing method has not satisfied each rolling stock section, factory is to the crudy requirement of coupler yoke key.
Summary of the invention
The purpose of this utility model is, provide a kind of rolling stock coupler yoke key two cambered surface production millers, to improve the quality of workpiece processing, improve the efficient of workpiece processing, improve automation degree of equipment, alleviate labor intensity of operating personnel, to satisfy and to improve the maintenance technological requirement of coupler yoke key processing.
The two cambered surface production millers of the utility model rolling stock coupler yoke key are realized by following technical proposals:
