[0019] Reference Figures 1 to 4 As shown, this utility model provides a clamping and positioning device for automobile door panels and patch panels, including: a flexible working platform 1 and an automobile door panel 4, wherein the automobile door panel 4 is clamped and positioned at the upper end of the flexible working platform 1.

[0020] The upper surface of the flexible work platform 1 is supported by a workpiece support plate 2 via a support rod 21. A clamping pressure plate 3 is distributed on the upper end of the workpiece support plate 2. A high-strength welding clamping cylinder 22 is connected to the side end of the clamping pressure plate 3 via a connecting block 31. The clamping pressure plate 3 is connected to a limit pressure column 35 via a limit groove 34. A spring 33 is connected to the upper end of the limit pressure column 35. An adjusting plate 5 is inserted into the lower end of the car door panel 4. A support plate 55 is connected to the lower end of the adjusting plate 5 via a connecting key 54. An adjusting stud 51 is connected to the inner end of the support plate 55 via a drive block 57. A support base 52 is connected to the lower end of the adjusting stud 51 via a bearing.

[0021] First, take the car door panel and patch panel to be welded to the upper end of the flexible work platform 1. First, position and insert the car door panel and patch panel into the positioning pin 53 on the adjustment plate 5. Rotate the adjustment stud 51 to adjust the height of the adjustment plate 5 so that the lower end face of the car door panel and patch panel is in contact with the upper surface of the workpiece support plate 2. Then, move the multiple positioning components on the flexible work platform 1 so that the upper and lower surfaces of the car door panel and patch panel are clamped with the clamping pressure plate 3 and the workpiece support plate 2. Then, fix the clamped positioning components with the fixing holes 11 of the workpiece support plate 2 to complete the clamping and positioning operation of the car door panel and patch panel.

[0022] In this embodiment, the flexible work platform 1 has fixed holes 11 at equal intervals on its surface, and the flexible work platform 1 is connected to the workpiece support plate 2 and the support base 52 through the fixed holes 11 respectively.

[0023] As a preferred embodiment, the flexible work platform 1 uses multiple sets of fixing holes 11 to facilitate the positioning of the clamping and positioning components of the car door panel and patch panel, so that the car door panel and patch panel can be stably placed at the upper end of the flexible work platform 1.

[0024] In this embodiment, a rotary positioner 6 is connected to the lower end of the flexible work platform 1, a workpiece support plate 2 is fixed to the upper end of the support rod 21, and a high-strength welding clamping cylinder 22 is installed on the side end of the support rod 21.
