A Friction Stir Welding Device for Aerospace Cylinder Structural Parts

Abstract

The invention discloses a stir friction welding device for an aerospace cylinder structural part. The stir friction welding device comprises telescopic supporting rods. The top ends of the telescopicsupporting rods are in welding connection with a top fixing plate, the middle of the top fixing plate is connected with middle connecting rods through sleeves, the middle connecting rods are sleeved with sliding sleeves, and middling fixing blocks are arranged between the sliding sleeves. The top ends of second automatic telescopic rods are connected with driven gear discs through bearings, the lower parts of the driven gear discs are in meshed connection with a driving gear disc, the middle of the driving gear disc is connected with a rotating shaft, stir friction heads are arranged at the top ends of the driven gear discs, and a fixing installation plate connected through connecting shafts is arranged on the upper parts of the middle fixing blocks. In the use process of the stir frictionwelding device for the aerospace cylinder structural part, stir heads can be regulated automatically to make the whole welding process in a consecutive state, and the working efficiency of the wholedevice is high.

Description

technical field [0001] The invention relates to the technical field related to friction stir welding of aerospace cylinders, in particular to a friction stir welding device for structural parts of aerospace cylinders. Background technique [0002] Friction stir welding is the same as the conventional welding method. It is a connection method that heats metals to fix the metals. Friction stir welding is a method that uses frictional heat and plastic deformation heat as heat sources. A welding method, however, although there are many types and quantities of friction stir welding devices in the existing market, it still has some problems. The problem of damage often occurs, which makes it necessary to frequently replace the stirring head during the entire welding process. During the replacement process, it will consume a lot of time, making the work efficiency of the entire friction stir welding low. , and in the process of welding, due to the external shape of the whole devic...
