[0040] Specifically, after the arc and angle of the welded part are adjusted, the welded part is fixed by using the welded part fixing assembly 10, and the process is as follows: the welded part is placed between the fixed clamp seat 1001 and the movable clamp seat 1002, and after the position is adjusted, the second hydraulic cylinder 1008 is started to drive the movable clamp seat 1002 to move closer to the fixed clamp seat 1001. During the process, the rollers 1010 on the two attached blocks 1009 will contact the welded part first, and as the distance between the fixed clamp seat 1001 and the movable clamp seat 1002 continues to decrease, the reset spring 1012 is compressed and elastically deformed, and the attached block 1009 is pressed toward the fixed clamp seat 1001 or the movable clamp seat 1002 until the outer wall of the welded part contacts and squeezes the rubber contact 1014 on the T-shaped mounting seat 1013;

[0042] Reference Figure 1 and Figure 7 An angle disc 11 is connected to the side of the workbench 1 away from the position adjustment motor 8 by bolts, and a scale line 12 is set on the angle disc 11. A rectangular installation groove is opened on the same side of the workbench 1, and an infrared transmitter 13 is connected to the inside of the rectangular installation groove by bolts.

[0043] Specifically, when adjusting the position of the welding spot, the angle between the lower support 303 and the upper support 304 can be compared on the angle plate 11, and the infrared emitter 13 is used to determine that the welding spot is centered to ensure the welding effect.

[0044] Working principle: When in use, the arc adaptability component of the welded part is adjusted according to the arc of the welded part. The process is: start the first hydraulic cylinder 602 to extend and retract to apply a pulling force or a pushing force to the tailstock 601, the lower support 303 moves laterally on the lower support 301, and the upper support 304 moves laterally on the upper support 302, and the rotation radius of the front end of the lower support 303 and the upper support 304 is changed (when the arc of the welded part is small, the first hydraulic cylinder 602 is extended and retracted, and the rotation radius of the lower support 303 and the upper support 304 on the base 2 is changed). The diameter increases. When the arc of the weldment is large, the first hydraulic cylinder 602 extends, and the rotation radius of the lower support 303 and the upper support 304 on the base 2 is reduced). Subsequently, the angle adjustment motor 306 is started to drive the screw 308 to rotate. Since the internal threads of the threaded holes on the lower support 301 and the upper support 302 are opposite, the rotation of the screw 308 will drive the lower support 301 and the upper support 302 to deflect in opposite directions, so that the angle between the lower support 303 and the upper support 304 changes until the length placement requirement of the weldment is met;

[0045] The weldment is fixed by using the weldment fixing assembly 10, and the process is as follows: the weldment is placed between the retaining clamp seat 1001 and the movable clamp seat 1002, and after adjusting the position, the second hydraulic cylinder 1008 is started to drive the movable clamp seat 1002 to move closer to the retaining clamp seat 1001. During the process, the rollers 1010 on the two attached blocks 1009 will contact the weldment first, and as the distance between the retaining clamp seat 1001 and the movable clamp seat 1002 continues to decrease, the return spring 1012 is compressed and elastically deformed, and the attached block 1009 is pressed toward the retaining clamp seat 1001 or the movable clamp seat 1002 until the outer wall of the weldment contacts and squeezes the rubber contact 1014 on the T-shaped mounting seat 1013;

[0046] After the weldment is placed, the weldment adjustment assembly 7 is adjusted according to the position of the weldment, and the process is as follows: the deflection adjustment motor 703 is started to drive the driving gear 704 to engage the annular sleeve gear 702, and the lower support seat 301 and the upper support seat 302 are deflected as a whole until the weldment is aligned; while adjusting the weldment, the position adjustment motor 8 drives the screw rod 9 to rotate, and the base 2 moves laterally on the workbench 1, so that the placed weldment is adjusted laterally with it; during the whole process, the angle between the lower support platform 303 and the upper support platform 304 can be compared on the angle disk 11, and the infrared emitter 13 is used to determine that the weldment position is centered.
