[0018] Refer to Figures 1 to 4As shown in the figure, the utility model provides a vehicle body repair welding fixture, which includes: a base plate 1 and a fixing plate 8. The lower surface of the base plate 1 is movably connected to a base 2 through a bearing. A buffer groove 5 is provided inside the base 2. A pedal 3 is slidably connected to the buffer groove 5 through a positioning rod 4. The upper surface of the pedal 3 is symmetrically connected with fitting rods 6, and the fitting rods 6 are slidably connected in fitting holes. The base 2 and the base plate 1 are both provided with fitting holes. The upper surface of the base plate 1 is symmetrically connected with columns 7. The upper ends of the columns 7 are movably connected to a main rotating shaft 12 through bearings. One end of the main rotating shaft 12 is fixedly connected to the fixing plate 8, and the other end of the main rotating shaft 12 is screwed with a fastening ring 10. At the same time, one end of the main rotating shaft 12 close to the fastening ring 10 is slidably connected to a fastening component 11. The middle part of the fixing plate 8 is movably connected to an adjusting screw rod 14 through a bearing. The two ends of the adjusting screw rod 14 are symmetrically screwed with clamping plates 16. A buffer layer 17 is fixedly connected to the surface of the clamping plate 16. Receiving grooves are symmetrically provided on the surface of the buffer layer 17. Screw holes are correspondingly provided on the surface of the clamping plate 16 at positions opposite to the receiving grooves. At the same time, a fastening bolt 13 is screwed in the screw hole, and one end of the fastening bolt 13 located in the receiving groove is fixedly connected to a reinforcing component 15.

[0019] In this embodiment, the vehicle door is embedded between two sets of fixed plates 8. The bent portions of the fixed plates 8 can lift the vehicle door, thereby reducing the difficulty of subsequent clamping and fixing. First, rotate the adjusting screw rod 14. The adjusting screw rod 14 pushes the two sets of clamping plates 16 connected by threads to move relative to each other. Then, the two sets of clamping plates 16 can abut against the surface of the vehicle door through the buffer layer 17 to complete the preliminary clamping and fixing of the vehicle door. Then, selectively rotate the fastening bolt 13 according to the actual situation. The fastening bolt 13 will push the corresponding reinforcement assembly 15 to abut against the position of the vehicle door that is not clamped and fixed, thereby further enhancing the clamping and fixing effect of the fixture on the vehicle door. As the worker's repair welding process progresses, when it is necessary to adjust the position of the vehicle door, rotate the fastening ring 10. The fastening ring 10 moves away from one end of the column 7, thereby releasing the restriction between the fastening assembly 11 and the column 7, enabling the worker to drive the vehicle door to rotate in the vertical plane through the fixed plate 8. When the vehicle door is rotated properly, reverse-rotate the fastening ring 10 so that the fastening ring 10 pushes the fastening assembly 11 to abut against the surface of the column 7, thereby completing the fixed connection between the fixed plate 8, the main rotating shaft 12, and the column 7. When it is necessary to flip the vehicle door in the horizontal direction, first step on the pedal 3. While stretching the spring, the pedal 3 will also drive the fitting rod 6 to move downward synchronously. Then, the fitting rod 6 can be disengaged from the fitting hole opened on the substrate 1, releasing the restriction between the base 2 and the substrate 1. At this time, rotate the substrate 1 so that the fitting hole of the substrate 1 is misaligned with the fitting rod 6. Then release the pedal 3, and the pedal 3 will reset under the action of the stretched spring. When the substrate 1 rotates half a circle, the worker steps on the pedal 3 again so that the fitting rod 6 is received in the fitting hole opened on the base 2. Adjust the position of the substrate 1 so that the opening of the fitting hole of the base 2 is blocked. After releasing the pedal 3, fine-tune the position of the substrate 1 again so that the fitting rod 6 can be directly opposite to the fitting hole opened on the substrate 1 to ensure that the fitting rod 6 can be smoothly embedded, completing the fixation of the base 2 and the substrate 1, thereby realizing the convenient flipping and rotation of the vehicle door, ensuring the personal safety of the worker, and improving the efficiency of vehicle door repair welding.

[0020] As a preferred embodiment, the substrate 1 has an I-shaped structure. The two sets of columns 7 fixedly connected to both ends of the upper surface of the substrate 1 are both rectangular parallelepiped structures, and two sets of universal wheels are symmetrically connected to the lower surfaces of both ends of the substrate 1. At the same time, the substrate 1 and the columns 7 are combined to form a U-shaped structure.

[0021] In this embodiment, as Figure 1 and Figure 3 , the universal wheels provided on the lower surface of the substrate 1 can assist in enhancing the convenience of the substrate 1 driving the vehicle door to rotate and improving the efficiency when the vehicle door is flipped. At the same time, the setting of the columns 7 can ensure that the fixture can stably clamp the vehicle door.

[0022] As a preferred embodiment, the base 2 has a square structure, the buffer groove 5 formed in the base 2 has a rectangular structure, and a plurality of positioning rods 4 are fixedly connected in parallel and at equal intervals in the buffer groove 5. The plurality of positioning rods 4 are all cylindrical structures, and the pedal 3 has a rectangular structure. Through holes are correspondingly formed in the surface of the pedal 3 at positions corresponding to the positioning rods 4. At the same time, springs are sleeved on the upper ends of the positioning rods 4, and the two ends of the springs are respectively fixedly connected to the upper surface of the pedal 3 and the top of the buffer groove 5.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 , the sizes of the pedal 3 and the buffer groove 5 are adapted to each other, which can assist in reducing the probability of shaking when the pedal 3 moves in the buffer groove 5. The sizes of the positioning rods 4 and the through holes are adapted to each other, which can further enhance the stability of the pedal 3 when moving. At the same time, the setting of the springs enables the pedal 3 to have an automatic reset effect after being stepped on.

[0024] As a preferred embodiment, one end of the main rotating shaft 12 away from the fixed plate 8 is screwed with a fastening ring 10 through a threaded structure. The fastening ring 10 has a circular ring structure, and the fastening assembly 11 is composed of a fastening plate and a cross plate. The fastening plate has a circular ring structure, and the cross plate has a rectangular structure. Limit grooves are correspondingly formed on the surface of the main rotating shaft 12 at positions corresponding to the cross plate. At the same time, a plurality of convex blocks are evenly fixedly connected to the surface of the column 7 at positions corresponding to the fastening assembly 11, and fastening layers are correspondingly connected to the surface of the fastening plate at positions corresponding to the convex blocks.

[0025] In this embodiment, as Figure 1 , Figure 3 and Figure 4 , the fastening layer is made of soft rubber material, and the convex blocks have a hemispherical structure. Therefore, when the fastening ring 10 pushes the fastening assembly 11 to abut against the surface of the column 7, the fastening layer in the fastening assembly 11 can be squeezed by the convex blocks, thereby increasing the frictional resistance between the fastening assembly 11 and the column 7 and enhancing the fixing effect of the main rotating shaft 12 and the fixed plate 8. At the same time, the setting of the cross plate can prevent the problem of relative rotation between the fastening assembly 11 and the main rotating shaft 12.

[0026] As a preferred embodiment, the two fitting rods 6 fixedly connected to both sides of the upper surface of the pedal 3 are both cylindrical structures, the opening of the fitting hole formed in the lower surface of the substrate 1 has a frustum shape, and the sizes of the fitting rods 6 and the fitting holes are adapted to each other. At the same time, anti-slip layers are symmetrically formed at both ends of the upper surface of the pedal 3.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3, the sizes of the fitting rod 6 and the fitting hole are adapted to each other, which can then assist in enhancing the stability of the connection between the base 2 and the substrate 1. Moreover, the structure of the fitting hole provided on the substrate 1 can effectively reduce the difficulty of inserting the fitting rod 6, ensuring that the base 2 and the substrate 1 can be quickly and fixedly connected.

[0028] As a preferred embodiment, the fixing plate 8 has an L-shaped structure. The through groove provided in the bent portion of the fixing plate 8 has a rectangular structure. And a plurality of guide rods 9 are fixedly connected to the main body portion of the fixing plate 8 at equal intervals along the length direction.

And a buffer layer 17 is fixedly connected to the side of the clamping plate 16 that is not facing the fixing plate 8. The buffer layer 17 has a strip-shaped structure.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 3 , the buffer layer 17 is made of silica gel material, which can then assist in enhancing the stability when the clamping plate 16 clamps the car door, and can also effectively reduce the probability of the car door surface being accidentally scratched. At the same time, the setting of the bent portion of the fixing plate 8 can perform corresponding auxiliary lifting during the process of the fixture clamping the car door, thereby reducing the fixing difficulty when the worker clamps the car door.

[0030] As a preferred embodiment, a plurality of storage grooves are provided in the buffer layer 17 at equal intervals in parallel along the length direction. The storage grooves have a cylindrical structure. And the reinforcement component 15 slidably connected in the storage groove is composed of a push plate and an extrusion layer. The sizes of the reinforcement component 15 and the storage groove are adapted to each other. And fastening bolts 13 and an extrusion layer are respectively fixedly connected to both sides of the push plate.

[0031] In this embodiment, as Figure 1 , Figure 2 and Figure 3 , the extrusion layer is made of silica gel material, which can then assist in enhancing the clamping and fixing effect of the fastening bolts 13 and the reinforcement component 15 on the car door surface, so that the part of the car door in contact with the buffer layer 17 due to its own curvature can also be clamped and fixed, thereby enhancing the clamping and fixing effect of the fixture on the car door.

[0032] Through the cooperation of the fixing plate 8, the adjusting screw rod 14, the clamping plate 16, the fastening bolts 13 and the reinforcement component 15, the car body repair welding fixture of the present utility model can effectively enhance the fixing effect of the fixture on the car door.
