[0027] like Figure 1 and Figure 3 As shown, a collecting trough 4 is provided in the middle of the operating table 1; a collecting box 41 is fixedly connected to the bottom of the operating table 1; the collecting trough 4 and the collecting box 41 are correspondingly arranged; during operation, more welding slag will be generated during welding, and when the angle of the part is adjusted by rotating, the welding slag will fall from the part, and at this time, the welding slag will enter the collecting box 41 through the collecting trough 4 and be collected. Through the above structure, the collecting trough 4 and the collecting box 41 are arranged, and the welding slag falling from the part can be collected during welding, so as to reduce the pollution and corrosion caused by the accumulation of welding slag on the surface of the operating table 1.
[0028] like Figure 3 As shown, the side wall of the collecting box 41 is provided with an opening 5; a drawer box 51 is placed in the collecting box 41; the collecting box 41 and the drawer box 51 are slidably matched; during operation, when the welding slag enters the collecting box 41, the drawer box 51 is located in the collecting box 41, and the welding slag enters the drawer box 51 and is collected.

Through the above structure, the rubber pad 7 is arranged to connect the clamping jaw 23, which can reduce the wear caused by extrusion between the clamping jaw 23 and the part when the clamping jaw 23 clamps and fixes the part, so as to improve the stability during use.
[0031] Working principle: When welding the shaft parts of the automobile, the parts are fixed in position by the fixing assembly. When welding, the linear motor 11 is started to drive the first fixing plate 12 and the first cylinder 13 to move horizontally. When aligned with the welding position of the parts, the first cylinder 13 is started to drive the air guide cover 18 to move longitudinally to the welding position. At this time, the air intake pipe 14 is a hose structure and can move with the air guide cover 18. When the air guide cover 18 is close to the welding position, it stops moving. At this time, the air pump 16 is started to drive the airflow from the air guide cover 18 into the air intake pipe 14. When the airflow is flowing, the smoke and exhaust gas generated during welding can be sucked away and enter the filter box 15. At this time, the activated carbon placed in the filter box 15 can absorb the smoke and exhaust gas in the airflow, and then the airflow is discharged from the air pump 16. When fixing the shaft parts of the automobile, the parts are placed between the pneumatic chucks 22 on both sides, and then the second cylinders 21 on both sides are started to stretch, driving the pneumatic chuck 22 to move toward the surface of the parts. When the pneumatic chuck 22 contacts the parts, the clamping claws 23 contracts and contacts with the surface of the part, and the part can be clamped and fixed, and then welding work is carried out. Starting the motor body 3 can drive the rotating shaft 31 to rotate. At this time, the rotating shaft 31 is connected to the pneumatic chuck 22, and the pneumatic chuck 22 can be driven to rotate. At this time, when the part is clamped and fixed on the pneumatic chuck 22, the angle of the part can be adjusted by rotating. When welding, more welding slag will be generated. When the angle of the part is adjusted by rotating, the welding slag will fall from the part. At this time, the welding slag will enter the collection box 41 through the collection groove 4 and be collected. When the welding slag enters the collection box 41, the drawer 51 is located in the collection box 41 at this time, and the welding slag will enter the drawer 51 and be collected. When the collection is completed, the drawer 51 can be drawn out, the collected welding slag can be poured out, and then the drawer 51 can be put back into the collection box 41. When the welding slag and fine particles generated during welding fall toward the linear motor 11, they will be blocked by the protective cover 6 to block the welding slag and fine particles outside the linear motor 11. When the clamp 23 clamps and fixes the part surface, the rubber pad 7 will contact the part surface.
