So, a welding seam compresses tightly subassembly 23 can compress tightly two bar shaped plates simultaneously, simple structure.
Each first limiting component of the first positioning component can be arranged at the end part of a seam between adjacent strip-shaped plates, and the positions of the two strip-shaped plates can be adjusted and positioned simultaneously by one first limiting component, so that the structure is simplified. Because the welding seam compresses tightly the tip of subassembly 23 also setting up the seam between the adjacent lath, for avoiding producing the interference between first spacing subassembly and the welding seam compresses tightly the subassembly 23, set up the first kicking block 13 of first spacing subassembly into the shape as shown in fig. 4, including with the tight portion 31 in the top of the second connecting portion 30 of the working end fixed connection of first side top cylinder 12 and two settings side by side, have the interval between two tight portions 31 in the top, this interval is greater than the working space that the welding seam compressed tightly the subassembly 23. When the first ejector block 13 positions and adjusts the position of the bottom plate 1, the two abutting portions 31 abut against the bottom plate 1 on both sides of the weld respectively.
In a preferred embodiment of the present embodiment, a first inductive switch in communication connection with the first control system is disposed on the weld pressing assembly 23, and the first inductive switch may be a magnetic induction switch. When friction stir welding is carried out, if the stirring pin is close to the first inductive switch, the first inductive switch sends a signal to the first control system, the first control system generates a corresponding signal and sends the signal to the corresponding welding seam pressing assembly 23, so that the pressing of the bottom plate 1 is released, and the stirring pin is prevented from colliding with the welding seam pressing assembly 23. If the corresponding seam pressing assembly 23 does not release the pressing of the base plate 1 at this time, the first control system communicates with the friction stir welding device to stop the operation of the stirring pin.
