[0045] Specifically, the base frame assembly 10 can be welded with square tubes made of Q235 material to ensure the overall frame strength of the fixture. Among them, the base frame 11 is a rectangular structure, surrounded by four square tubes, and at least one set of opposite sides is connected with two square tubes to enhance rigidity and stability. The support frame 12 is located in the middle of the base frame 11, and the support frame 12 is a rectangular parallelepiped structure welded to the base frame 11. The door frame 13 is a door-shaped structure, which is horizontally placed above the support frame 12, and the two ends of the door frame 13 are connected to the base frame 11. The first positioning member 21 in the flip positioning assembly 20 corresponds to the first positioning member 21 on the left side of the vehicle body for positioning and supporting the driver's door upper frame, the first positioning member 21 corresponding to the right side of the vehicle body is used to position and support the front door upper frame, the second positioning members 22 corresponding to the left and right sides of the vehicle body are used to position and support the left and right middle beams of the front face (lower cross beams of the triangular windows), and the third positioning members 23 corresponding to the left and right sides of the vehicle body are used to position and support the lower cross beam of the front windshield of the front face; the rotating limit frame 30 is used to position and support the floor of the front face.

Specifically, the stepping platform 40 is composed of at least two layers of square tubes to form a stepped structure, which is convenient for operators to step on and perform operations at high altitudes. Before the welding operation, after each skeleton square tube is placed and positioned, the skeleton square tube at the upper end of the front face assembly (such as a light box beam, etc.) needs to be placed and welded by the operator stepping on the stepping platform 40.

[0048] In the above embodiment, the door frame 13 includes two vertical frame parts 131 and a horizontal frame part 132 connected between the two vertical frame parts 131, and the first positioning member 21, the second positioning member 22 and the third positioning member 23 are sequentially arranged on the vertical frame parts 131 from top to bottom. Specifically, the two vertical frame parts 131 are symmetrically arranged on the base frame 11 and are located on the left and right sides of the support frame 12, and the horizontal frame part 132 is connected with the two vertical frame parts 131 to form a door-shaped structure, and the step platform 40 is respectively connected to the two vertical frame parts 131, and the first positioning member 21, the second positioning member 22 and the third positioning member 23 are sequentially arranged on the vertical frame parts 131 from top to bottom to respectively position and support each skeleton square tube of the front face.

Specifically, the second positioning portion 223 of the second positioning member 22 rotates in a plane parallel to the plane where the door frame 13 is located, and its rotation axis is perpendicular to the plane where the door frame 13 is located. During welding, the second positioning portion 223 rotates to be located inside the door frame 13, so as to facilitate positioning of the skeleton square tube through the second positioning groove 223a. After welding is completed, the second positioning portion 223 rotates to be located outside the door frame 13 to avoid causing hoisting interference to the skeleton assembly.

The third positioning portion 233 rotates in parallel to the horizontal plane, and its rotation axis is perpendicular to the horizontal plane; during welding, the third positioning portion 233 rotates to be located inside the door frame 13, and the opening of the L-shaped structure formed by the third positioning portion 233 and the connecting portion 232 faces away from the rotation limit frame 30, so as to facilitate positioning of the skeleton square tube through the third positioning groove 233a and the L-shaped structure; after welding is completed, the third positioning portion 233 rotates to be located outside the door frame 13 to avoid hoisting interference with the skeleton assembly.

[0053] See also Figure 1 In the above embodiment, the door frame 13 is further provided with an upper support frame 14 extending toward the support frame 12, and the upper support frame 14 includes two vertical support portions 141 and a horizontal support portion 142 connected between the two vertical support portions 141, and each of the vertical support portions 141 is in an L-shaped structure. Specifically, the upper support frame 14 is used to position the small assembly of the front face, and the upper support frame 14 is located in the middle of the horizontal frame portion 132 of the door frame 13.
