Chassis welding is an indispensable part of the automobile manufacturing process. It requires high-precision welding technology and professional equipment to ensure the quality and stability of welding. The automobile chassis welding assembly line was born to meet this demand. The chassis welding assembly line mainly transfers and welds different parts of the chassis, and then welds the sides of the chassis. After the sides are welded, the chassis is moved to the next work surface, and the sides and beams are spot welded into the front half frame, and then transferred to the next welding work for welding, and so on.

[0032] The locking swivel seat 5 comprises a base 501, in which a positioning cavity 502 is provided, in which the driving gear 14 is arranged, and a shift lock 1 6 and a shift lock 2 9 for clamping chassis accessories are arranged on the surface of the base 501.

The toothed driven roller 13 and the toothed driving roller 15 are connected by a toothed belt 12, and the base 501 is installed on the surface of the toothed driven roller 13.

[0034] The toothed belt 12 can drive the toothed driven roller 13 and the toothed driving roller 15 at the same time, thereby driving the base 501 to rotate and change the angle of the base 501. Then, when the shift lock 1 6 and the shift lock 2 9 are clamped, the clamping angle of the clamping position can be adjusted according to the angle of connection between the position of the accessory and the chassis, such as Figure 2 When the toothed driven roller 13 rotates, it is rotationally connected to the positioning disk 17 . The positioning disk 17 is arranged so that the toothed driven roller 13 can rotate on the surface of the positioning disk 17 .

When welding, the position of the accessories is guaranteed, and precise welding can be achieved. Figure 6 .

[0039] As an embodiment of the present invention, strip grooves 503 are respectively provided on both sides of the base 501 along its length direction, and the movable clamping plate 1 602 and the movable clamping plate 2 902 respectively pass through the strip grooves 503 to extend to the outside of the base 501, and rack grooves 504 are respectively provided on both sides of the base 501, and the shifting tooth plate 1 601 and the shifting tooth plate 2 901 are respectively arranged through the rack grooves 504.

[0040] Among them, Figure 5 The strip grooves 503 are respectively opened on the base 501 to provide channels for the driving movement of the movable clamping plate 1 602 and the movable clamping plate 2 902. The setting of the rack notch 504 can increase the stability when the shifting tooth plate 1 601 and the shifting tooth plate 2 901 move.

[0041] As an embodiment of the present invention, two guide slide bars 16 are installed on the surface of the base 501 , and fixed clamping plates 10 parallel to the movable clamping plate 1 602 and the movable clamping plate 2 902 are arranged at both ends of the base 501 .

[0049] The hydraulic rod 4 can be driven at the same time to drive the linear module 2 to move up and down to change the height;

[0050] When the driving motor 8 is started, the toothed belt 12 drives the toothed driven roller 13 to rotate, thereby rotating the base 501. Since the base 501 drives the fixed clamping plate and the movable clamping plate to move, and the movable clamping plate is connected to the surface of the driving gear 14 by the shifting tooth plate, when the base 501 rotates, the driving gear 14 is fixed, and the shifting tooth plate 1 601 and the shifting tooth plate 2 901 move on the surface of the driving gear 14, which will change the movement amplitude of the movable clamping plate to a certain extent.

[0051] The servo motor 18 drives the driving gear 14 to rotate, thereby moving the movable clamping plate 1 602 and the movable clamping plate 2 902 to move.
