[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a flip-over workbench for radiator welding, including a base 1, a pair of rotating sleeves 3, and a pair of crossbeams 5. A pair of supports 2 are fixedly mounted on the base 1. The pair of rotating sleeves 3 are rotatably mounted on the inner top of the pair of supports 2. A pair of pull rods 4 are fixedly mounted on one side of each end of the pair of crossbeams 5. The pull rods 4 are inserted into the inner side of the rotating sleeves 3. The spacing between the pair of crossbeams 5 is adjusted by adjusting the position of the pull rods 4 inside the rotating sleeves 3, so as to clamp radiators of different widths. Both the upper and lower surfaces of the crossbeams 5 are rotated. Multiple gears 6 are mounted on the radiator, and each gear 6 is equipped with a support plate 8 via an extension tube 7. Rotating the gear 6 by 90 degrees allows the support plate 8 to extend out of or retract into the crossbeam 5. When the support plate 8 extends out of the crossbeam 5, it can lift the edge of the radiator. When welding the upper surface of the radiator, retracting the support plate 8 into the crossbeam 5 can avoid the welding area, ensuring smooth welding. At this time, moving the radiator upwards allows it to be removed. Multiple gears 6 on one side of the crossbeam 5 can rotate synchronously, which in turn causes multiple support plates 8 to rotate synchronously.

[0021] As an embodiment of this utility model, a linkage plate 9 that can slide along its length direction is provided on both the upper and lower surfaces of the crossbeam 5. A rack 10 that meshes with multiple gears 6 is provided on the linkage plate 9. The multiple gears 6 can be driven to rotate simultaneously by moving the linkage plate 9.

[0022] As an embodiment of this utility model, the linkage plate 9 has an opening 11, and the crossbeam 5 is screwed with an anti-loosening screw 12. The opening 11 is fitted on the outside of the anti-loosening screw 12, and the diameter of the nut of the anti-loosening screw 12 is larger than the width of the opening 11.

[0023] As an embodiment of this utility model, a mounting cylinder 13 is fixedly provided at one end of the linkage plate 9. A positioning pin 14 is slidably provided inside the mounting cylinder 13. Two positioning holes 15 are provided on the crossbeam 5. After the positioning pin 14 is inserted into the positioning hole 15, the linkage plate 9 can be limited. A spring 16 is provided inside the mounting cylinder 13 for pushing the positioning pin 14 to move towards the positioning hole 15. A handle 17 is fixedly provided at one end of the outer side of the positioning pin 14. By pulling out the handle 17, the spring 16 can be compressed, which can push the crossbeam 5 to move. When the positioning pin 14 is inserted into one of the positioning holes 15, the support plate 8 can protrude out of the crossbeam 5. The radiator can be lifted by the protruding crossbeam 5. When the positioning pin 14 is inserted into the other positioning hole 15, the support plate 8 can be retracted into the crossbeam 5.

[0024] As an embodiment of this utility model, the pull rod 4 is provided with multiple threaded holes, and the end of the rotating sleeve 3 is equipped with a fastening screw 18. The fastening screw 18 matches the threaded holes. By aligning the threaded holes at different positions with the fastening screw 18, the distance between a pair of crossbeams 5 can be adjusted and positioned.

[0025] As an embodiment of this utility model, the gear 6 has a threaded hole on its surface. The support plate 8 and the extension tube 7 are fastened to the gear 6 with long screws 19, so as to realize the detachment and connection of the extension tube 7 and the support plate 8. By replacing the extension tube 7 and the long screws 19 with different lengths, the distance between the support plate 8 and the crossbeam 5 can be changed, so that the device can adapt to radiators of different thicknesses.

[0026] As an embodiment of this utility model, a mounting plate 20 is fixedly provided on the bracket 2, and a positioning rod 21 is inserted into the mounting plate 20. Two positioning cylinders 22 that match the positioning rod 21 are fixedly provided on the rotating sleeve 3. By inserting the positioning rod 21 into the positioning cylinder 22, the rotating sleeve 3 can be prevented from rotating.

[0027] The working principle and usage process of this utility model are as follows: During use, the spacing between a pair of crossbeams 5 is adjusted according to the width of the radiator, and extension tubes 7 of different lengths are selected according to the thickness of the radiator. When clamping, first adjust the support plate 8 below the crossbeam 5 to protrude from the crossbeam 5, and place the edge of the radiator on multiple support plates 8. At this time, the surface of the radiator located on the top can be welded. When it is necessary to flip, adjust the support plate 8 above the crossbeam 5 to protrude from the crossbeam 5, and then pull the positioning rod 21 out from the positioning cylinder 22. At this time, the radiator can be flipped. After flipping, reinsert the positioning rod 21 into the positioning cylinder 22 of the rotating sleeve 3 to complete the positioning of the rotating sleeve 3. Then, adjust the support plate 8 above the crossbeam 5 to be retracted into the crossbeam 5. At this time, the surface of the radiator located on the top can be welded.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
