[0011] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0012] Example

[0013] like Figure 1 , Figure 2 and Figure 3 As shown, the welding fixture for the steel radiator provided in this embodiment includes a base 1 and an L-shaped support platform 2 fixedly connected to one side of the base 1. A square workbench 3 is fixedly installed on the surface of the support platform 2. The four corners of the workbench 3 extend outward symmetrically to form mounting platforms 4. In this embodiment, several mounting holes are evenly opened on the mounting platforms 4. Clamping and fixing seats 5 are respectively installed on the four mounting platforms 4. The bottom of the clamping and fixing seats 5 has locking holes corresponding to the mounting holes.

[0014] Two clamping and fixing seats 5 on the same side along the length of the support platform 2 are respectively fixedly installed with top pressing cylinders 6 on opposite sides. Each clamping and fixing seat 5 is equipped with a rotating connector 7 that rotates with it. In this embodiment, the rotating connector 7 is a rotating shaft. The rotating shaft is installed on the clamping and fixing seat 5 through bearings and passes through both sides of the clamping and fixing seat 5. The two ends of the U-shaped connector 8 are respectively fixedly connected to the two ends of the rotating shaft, so that when the rotating shaft, i.e. the rotating connector 7, rotates, it can drive the U-shaped connector 8 to rotate around the rotating connector 7. The telescopic end of the top pressing cylinder 6 extends into the clamping and fixing seat 5 and is connected to a transmission component. In this embodiment, the transmission component is a linkage mechanism. The linkage mechanism is installed in the clamping and fixing seat 5. The driving end of the linkage mechanism is connected to the telescopic end of the top pressing cylinder 6, and the driven end of the linkage mechanism is connected to the middle of the rotating connector 7. That is, through the operation of the top pressing cylinder 6, the rotating connector 7 is driven to rotate, thereby causing the U-shaped connector 8 to rotate around the rotating connector 7.

[0015] A clamping rod 9 is fixedly installed on the inner side of the U-shaped connector 8. An outer edge clamping block 10 is formed at the bottom of the clamping rod 9. Several clamping holes 24 are opened at the top of the clamping rod 9 along the length of the support platform 2. A corresponding connecting rod is provided at the clamping hole 24. A top clamping seat 11 is fixedly connected to the bottom end of the connecting rod. In this embodiment, the flipping of the U-shaped connector 8 causes the outer edge clamping block 10 and the top clamping seat 11 to flip up or press down. When flipped up, the product is inserted; when pressed down, the product is fixed.

[0016] A support plate 12 is installed between the tops of two clamping and fixing seats 5 on the same side along the length of the support platform 2. A support block 13 is fixedly installed on the support plate 12. A limiting plate 17 and a connecting plate 18 are respectively installed on the outer side of the top of the clamping and fixing seat 5 near the end of the support platform 2. One end of the limiting plate 17 and the connecting plate 18 is fixedly installed on the top surface of the clamping and fixing seat 5, and the other end is a free end. A side positioning block 14 is fixedly installed on the limiting plate 17 and the connecting plate 18 near the clamping and fixing seat 5. A side pressing block 15 is provided on the outer side of the clamping and fixing seat 5 opposite to the side positioning hole. The side pressing block 15 corresponds to the side positioning block 14. A connecting frame is fixedly connected to the bottom of the side pressing block 15. A side pressing cylinder 16 is fixedly installed on the outer side of the middle part of the support plate 12. The telescopic end of the side pressing cylinder 16 is fixedly connected to the inner side of the connecting frame. When the side pressing cylinder 16 works, it drives the connecting frame to move along the length of the support platform 2, that is, it drives the side pressing block 15 to move closer to or away from the side positioning block 14.

[0017] The end of the limiting plate 17 away from the clamping and fixing seat 5 is equipped with an end face positioning block 19. Several adjustment holes 20 are opened on the side wall of the connecting plate 18 along its length direction. An adjustment seat 21 that slides with the connecting plate 18 is also snapped on it. The adjustment seat 21 is provided with a locking screw 22 that cooperates with the adjustment hole 20. A baffle 23 is installed on the adjustment seat 21.

[0018] In use, control the top clamping cylinder 6 and the side clamping cylinder 16 to operate, causing the top clamping seat 11 and the outer edge clamping block 10 to flip upwards, and causing the side clamping block 15 to move away. Then, place the workpiece on the surface of the support block 13, and place the end face of the workpiece against the surface of the end face positioning block 19, and place one side of the workpiece against the surface of the side positioning block 14, thereby quickly completing the positioning of the workpiece in the X and Y axis directions. After positioning is completed, control the side clamping cylinder 16 to operate, causing the side clamping block 15 to move towards the side wall of the workpiece and clamp it in place. Then control the top clamping cylinder 16 to operate, causing the side clamping block 15 to move towards the side wall of the workpiece and clamp it in place. When cylinder 6 operates, it drives the outer edge clamping block 10 and the top clamping seat 11 to flip towards the workpiece, so that the outer edge clamping block 10 presses down on the outer edge of the workpiece side wall, and the top clamping seat 11 presses down on the top surface of the workpiece, thus completing the clamping of the workpiece. After the workpiece is clamped, in order to ensure the clamping accuracy and clamping stability of the workpiece, the sliding adjustment seat 21 is adjusted according to the workpiece size, so that the baffle 23 on the adjustment seat 21 abuts against the other end face of the workpiece, and then the adjustment seat 21 is fixed by the locking screw 22. The setting of the baffle 23 not only ensures the stability of the clamping, but also provides a safety measure to prevent the workpiece from falling.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and substitutions based on the technical solutions and utility model concepts provided by the present utility model should be covered within the protection scope of the present utility model.
