[0028] The fixing mechanism 3 is arranged at the lower side of the welding mechanism 2 and is used to fix the welding mechanism 2. The fixing mechanism 3 includes an adjusting column 31, a fixing plate 32 and an adjusting nut 33. The adjusting column 31 is connected to the lower end of the welding frame 21, and the fixing plate 32 is slidably connected to the adjusting column 31.

Through the setting of the fixing mechanism 3, the welding mechanism 2 can be fixed to the position where disassembly operation is required, thereby facilitating the disassembly of broken threaded parts at various positions and directions on the equipment.

[0029] A welding monitoring mechanism 4 for monitoring the welding state is also provided on the lower side of the welding mechanism 2. The welding monitoring mechanism 4 includes a touch screen 41, a microcontroller 42 and a signal line 43. The touch screen 41 and the microcontroller 42 are installed on the welding frame 21. The touch screen 41 and the microcontroller 42 are connected by a signal line 43. The camera 44 and the infrared temperature sensor 46 are installed on the welding frame 21 through a hinge 45, and the camera 44 and the infrared temperature sensor 46 are facing the lower end position of the welding head 27. One end of the camera 44 and the infrared temperature sensor 46 is hinged to the connecting seat 26 through a connecting rod 47, and is used to control the angle of the camera 44 and the infrared temperature sensor 46. Through the setting of the welding monitoring mechanism 4, the welding position and welding temperature of the welding head 27 can be monitored in real time, thereby preventing the welding head 27 from being offset and causing damage to the threaded hole or the workpiece.

[0030] A boosting assembly 5 for boosting the welding mechanism 2 is installed on the support frame 1, and the boosting assembly 5 includes a hydraulic pump 51, a servo motor 52 and an oil storage tank 53. The hydraulic pump 51 is installed on the support frame 1, and a servo motor 52 for driving the hydraulic pump 51 to rotate is installed on one side of the hydraulic pump 51.

Through the setting of the power supply component 7, various electrical components on the disassembler can be stably powered.

[0033] The working process of the present invention is as follows:

[0034] When it is necessary to disassemble the broken threaded part, first remove the welding mechanism 2 from the support frame 1, and fix the welding mechanism 2 to the position where the workpiece is to be disassembled through the fixing mechanism 3, or fix the workpiece to the welding frame 21, and then select an appropriate welding head 27 according to the size of the broken threaded part, and install the welding head 27 on the connecting seat 26, and start the heating wire in the connecting seat 26 to heat the welding head 27; start the servo motor 52 to drive the hydraulic pump 51 to operate, and the hydraulic pump 51 will pump the oil storage through the electromagnetic reversing valve 54 and the overflow valve. The oil in the box 53 is transported to the booster cylinder 23. The hydraulic cylinder 24 causes the connecting seat 26 to move closer to the workpiece through the pressurized effect of the booster cylinder 23. The connecting seat 26 drives the welding head 27 to contact and press the broken head threaded part, thereby achieving pressure welding of the welding head 27 and the broken head threaded part together. During the welding process, the welding position and temperature can be monitored by the camera 44 and the infrared temperature sensor 46, and displayed on the touch screen 41, thereby ensuring the welding accuracy of the welding head 27 and avoiding damage to the workpiece or the threaded hole.

[0035] During the movement of the connecting seat 26, the connecting seat 26 drives the camera 44 and the infrared temperature sensor 46 to rotate a certain angle through the connecting rod 47, so that the camera 44 and the infrared temperature sensor 46 can always monitor the position and temperature of the welding head 27; after the welding of the welding head 27 is completed, the welding head 27 is separated from the connecting seat 26, and then the disassembly head 63 is plugged into the welding head 27, and the reduction motor 61 is started to drive the disassembly head 63 and the welding head 27 to rotate, so that the broken head threaded part is rotated to realize its non-destructive disassembly.
