Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1

[0046] Depending on the usage requirements, it can be selected whether to install the fixing bracket 41 on the turntable 32. When the fixing bracket 41 is not needed, the frame can be fixed on the turntable 32. The drive gear set 33 can drive the rotating shaft 31 and the turntable 32 to rotate simultaneously (at this time, the turntable 32 is flipped in the adjustment groove 2), thereby enabling the frame fixed on the turntable 32 to be flipped to a different position, which is convenient for welding operations.

[0047] When it is needed to fix the vehicle frame on the fixing frame 41, the distance between the movable frame one 42 and the movable frame two 43 on the fixing frame 41 can be adjusted according to the length of the vehicle frame, that is, the movable frame one 42 and the movable frame two 43 are moved towards or away from the fixing frame 41 (screws corresponding to the movable frame one 42 and the movable frame two 43 are arranged on the fixing frame 41, and a plurality of screw holes are arranged on the movable frame one 42 and the movable frame two 43, so that after the positions of the movable frame one 42 and the movable frame two 43 are adjusted, the movable frame one 42 and the movable frame two 43 are connected with the fixing frame 41 through the screws in the corresponding screw holes, so as to improve the connection stability); after the vehicle frame is placed on the fixing frame 41, the hooks 46 are hooked at the corresponding positions of the vehicle frame, so that the vehicle frame is lifted under the action of the hooks 46, and welding operation can be performed at this time (the welding machine can be arranged at a position corresponding to the platform seat 1 according to the need, and the welding machine is a prior art, so it is not described here, and the drawing is not drawn either); when it is needed to turn the vehicle frame placed on the fixing frame 41 by 180 degrees in the vertical direction, the two upright columns 44 on the movable frame two 43 are rotated towards the fixing frame 41, and the hooks 46 on the two upright columns 44 of the movable frame two 43 are hooked at the corresponding positions of the vehicle frame close to the movable frame one 42; the two upright columns 44 on the movable frame one 42 are rotated towards the fixing frame 41, and the hooks 46 on the two upright columns 44 of the movable frame one 42 are hooked at the corresponding positions of the vehicle frame close to the movable frame two 43; then the two upright columns 44 on the movable frame two 43 are rotated away from the fixing frame 41, and the two upright columns 44 on the movable frame one 42 are rotated away from the fixing frame 41, so that the vehicle frame placed on the fixing frame 41 is turned by 180 degrees.

[0054] When only the frame needs to be hung up, the arc-shaped hook 462 can be hooked on the corresponding position of the frame, the arc-shaped auxiliary hook 463 can be in contact with the frame under the action of the rotating shaft one 464 with a torsional spring (at the same time, the anti-falling hook one 466 can be in contact with the frame under the action of the rotating shaft two 465 with a torsional spring, and the anti-falling hook two 468 can be in contact with the frame at the corresponding position under the action of the rotating shaft three 467 with a torsional spring; rubber pads can be arranged at the positions where the anti-falling hook one 466 and the anti-falling hook two 468 are in contact with the frame, so as to buffer the collision force between them), which is conducive to preventing or avoiding the disengagement between the arc-shaped hook 462 and the frame, improving the safety, and also reducing the shaking friction between the frame and the arc-shaped hook 462 after being hung up; according to the convenience of welding operation, the distance between the frame and the fixed frame 41 can be adjusted by rotating the two columns 44 on the movable frame one 42 or the two columns 44 on the movable frame two 43.

[0055] The active frame one 42 and the active frame two 43 are provided with a plurality of turnover motors 47 corresponding to the columns 44, the columns 44 are fixedly arranged on the output shafts of the turnover motors 47, and the hooking grooves 45 are arranged at the ends of the columns 44 away from the turnover motors 47; when the height of the vehicle frame hung needs to be adjusted, the turnover motors 47 can be started to drive the four columns 44 to rotate towards the direction close to or away from the fixed frame 41, so that the position of the vehicle frame on the hooking 46 can be adjusted, and the convenience of the welding operation is improved.
