V-shaped thrust rod for phase position friction welding automobile and welding method for V-shaped thrust rod

Abstract

The invention discloses a V-shaped thrust rod for a phase position friction welding automobile and a welding method for the V-shaped thrust rod. One end of a first round pipe is welded to a first straight lug ring, and the other end of the first round pipe is welded to one branch end of a V-shaped lug ring. One end of a second round pipe is welded to a second straight lug ring, and the other end of the second round pipe is welded to the other branch end of the V-shaped lug ring. The first straight lug ring is placed in a rotation clamp of a double-head phase position friction welding machine clamped by a single-spindle box at a time to be clamped, the first round pipe is placed in an opposite-opening jaw of the friction welding machine, and the V-shaped lug ring is placed in a tail fixing clamp of the friction welding machine. After a weld opening between the first round pipe and the first straight lug ring is welded, the opposite-opening jaw is opened, a center frame is clamped, and the first round pipe is made to rotate. A spindle rotates to weld the part between the first round pipe and one branch end of the V-shaped lug ring, the first step is repeated, the V-shaped lug ring is vertically rotated by 180 degrees to be placed in the tail fixing clamp, then, the second round pipe and the second straight lug ring are welded, and finally, the second round pipe and the V-shaped lug ring are welded.

Description

technical field [0001] The invention relates to a V-shaped thrust rod for phase friction welding automobiles and a welding method thereof, and belongs to the technical field of V-shaped thrust rods and welding methods thereof. Background technique [0002] In the processing technology of thrust rod products for automobiles, thermocompression bonding is the main method. The thrust rod joint machine is added to the anti-retreat groove, and then the joint and the inner wall of the pipe are matched with the device to perform heating-pressure-forming on the hot press. This process Long processing cycle, high cost, and heavy weight of the finished thrust rod add an invisible burden to the vehicle, and long-term use is prone to serious problems such as looseness and buckle (see figure 1 ). Later, in the development of science and technology, the wide application of friction welding machines solved the above shortcomings. But it can only meet the production needs of straight thrus...
