Embodiment 1

[0045] Example 1. combine figure 1 and figure 2 , Take the automatic stud welding of a stud with a diameter of 19mm and a length of 52mm on a steel plate with a thickness of 60mm as an example. After welding, post-weld heat treatment is required. A steel stud with a diameter of 19mm and a length of 52mm and the ceramic ring matching the stud are pre-installed on the stud welding torch and the ceramic ring fixing device. Then the robot control system sends a series of control signals to complete the entire automatic welding process. The specific steps are as follows: (1) the robot moves to the workpiece at the stud to be welded, and the cylinder 3 moves to place the induction heating ring 13 on the stud to be welded. above the workpiece; (2) the induction welding machine 15 and the cooling water circulation system 16 are turned on to inductively heat the workpiece at the stud to be welded to about 600°C; (3) after the induction heating is completed, the cylinder 3 moves to i...

Abstract

The invention discloses a hybrid heat source stud welding method using a welding robot and a hybrid heat source stud welding system with the welding robot. The welding robot moves to a workpiece at the position of a stud to be welded, and a cylinder moves to place an induction heating ring on the workpiece at the position of the stud to be welded; an induction welder and a cooling water circulating system are started to perform induction heating for the workpiece at the position of the stud to be welded; the cylinder moves to lift the induction heating ring off the workpiece after induction heating; the welding robot moves to move a stud welding gun onto the workpiece at the position of the heated stud to be welded; the stud welding gun is started to weld the workpiece, and the welding robot moves to remove a head device and move the induction heating ring onto the welded stud; and post-weld heat treatment can be performed for the stud. The welding method and the welding system are used for automatically welding the stud with a hybrid heat source based on robot technology, and can be used for effectively integrating the automatic stud welding gun with the robot.

Description

technical field [0001] The invention belongs to a special welding technology for automatically welding medium and large-sized studs such as steel, aluminum, and copper on steel, aluminum, and copper substrates, in particular to a composite heat source stud welding robot welding method and a system thereof. Background technique [0002] The welding of steel matrix and steel, aluminum, copper studs is widely used in the hull cabin, inside the body of armored vehicles, the inner and outer walls of various pressure vessels, bridges and other fields, and the fields involved in stud welding are becoming more and more extensive. With the rapid development of modern industry, the utilization rate of studs is getting higher and higher, and the number of studs to be welded is also increasing. Modern machinery manufacturing technology requires that stud welding should be fast, reliable, simplified, easy to operate, and reduce costs. [0003] Arc stud welding method (ceramic ring prote...
