Two-sheet type wheel hub stirring friction welding device

Abstract

The invention discloses a two-sheet type wheel hub stirring friction welding device. The two-sheet type wheel hub stirring friction welding device comprises a spiral stirring pin, a thrust ball bearing, a pushing plate, a strain force sensor, a hydraulic cylinder, a rotating pressure shaft, a moving spline and a variable-frequency and variable-speed motor, wherein the spiral stirring pin is fixed at a first end of the rotating pressure shaft in a threaded mode, a second end of the rotating pressure shaft penetrates through the hydraulic cylinder, the second end portion is connected with the variable-frequency and variable-speed motor through the moving spline, the thrust ball bearing is arranged at the first end of the rotating pressure shaft, the strain force sensor used for pressure detection and control is arranged between the thrust ball bearing and the hydraulic cylinder, a thrust ball bearing seat is arranged outside the thrust ball bearing, and the pushing plate used for transmitting pressure is arranged between the thrust ball bearing seat and the strain force sensor. The two-sheet type wheel hub stirring friction welding device is simple in structure, low in energy consumption, easy to operate, and flexible and convenient to detach and install.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a two-piece hub friction stir welding device. Background technique [0002] Friction Stir Welding (FSW for short) is a new type of welding technology, which was invented by British Welding Institute in the early 1990s. Compared with traditional welding methods, friction stir welding has the advantages of high quality, high efficiency, low consumption, small welding deformation, and no pollution. It is especially suitable for welding non-ferrous metals. In recent years, friction stir welding technology has been rapidly promoted. , aerospace, shipbuilding, electric power, electronics and automobiles and other fields have been widely used. [0003] Since the friction stir welding process needs to overcome the huge resistance when the metal is stirred, and at the same time provide sufficient upsetting pressure, the currently commonly used friction stir welding equipment has the cha...

AI Technical Summary

Problems solved by technology

[0003] Since the friction stir welding process needs to overcome the huge resistance when the metal is stirred, and at the same time provide sufficient upsetting pressure, the currently commonly used friction stir welding equipment has the characteristics of complex structure, large volume, and is very expensive, and these equipment It is mainly used in the welding of large and medium-sized parts in the fields of aerospace, railway transportation, shipbuilding, etc., but for some small and medium-sized parts in the fields of machinery, electronics, home appliances, construction, etc., such as the welding of two-piece automobile wheels, there is no Corresponding simple friction stir welding equipment

Therefore, the application of friction stir welding technology in these fields has been greatly limited due to its unaffordable price or lack of suitable equipment.
