Embodiment Construction

[0027] Such as figure 1 As shown, the friction stir welding device mainly includes a main body frame unit 1 , a rotating telescopic arm unit 2 , an upper clamp 3 , a lower clamp 4 and a friction stir welding unit 5 . The main frame unit 1 is the structural foundation of the friction stir welding device, and provides the installation foundation for other units. The friction stir welding unit 5 can move vertically inside the main body frame unit 1 during welding operation. The function of the upper and lower clamps is to realize the positioning and fixing of the device on the side wall of the compartment. The rotating telescopic arm unit 2 provides the necessary upsetting force for the friction stir welding process inside the carriage. The friction stir welding unit 5 realizes the milling and welding operations on the damaged position.

[0028] Such as figure 2 As shown, the main frame unit 1 mainly includes an aluminum profile frame I6, a lifting drive motor 7, a lead scre...

Abstract

The invention provides a frictional stirring welding device for repairing a vehicle wallboard. The device comprises a friction stir welding device, a rotary flexible arm unit, an upper clamp, a lowerclamp and a main body frame unit. The friction stir welding device can mill and weld damaged positions of the vehicle wallboard, the rotary telescopic arm unit can provide an upsetting force in the welding process, the upper clamp and the lower clamp can fix the device to a wallboard of a car, and the stirring friction welding unit can move vertically in the main body frame unit. The device provided by the invention has the advantages of being good in weld joint quality, low in cost, high in efficiency, pollution-free and the like.

Description

technical field [0001] The invention relates to the technical field of vehicle maintenance devices, in particular to a friction stir welding device for repairing vehicle wall panels. Background technique [0002] The maintenance system of my country's railway vehicles adopts the principle of prevention first, which is divided into regular maintenance and operation maintenance. The repair program of regular vehicle inspection is divided into four levels of repairs: factory repair, section repair, auxiliary repair and axle inspection. Among them, the C80 vehicle cancels the auxiliary repair and is divided into two levels: factory repair and section repair. The factory repair cycle is 8 years or 160 days. 10,000 kilometers, the segment repair cycle is 2 years or 400,000 kilometers. The fundamental tasks of depot maintenance are: to keep the vehicle in good condition and performance before the next factory maintenance; to prolong the service life of vehicle accessories; to redu...
