[0015] Depend on Figure 1 to Figure 2 The utility model includes a device base 1, a first vertical platform 2 is fixedly installed at one end of the top of the device base 1, a rotatable first rotating shaft 3 is connected to one side of the upper part of the first vertical platform 2, one end of the first rotating shaft 3 is fixedly connected to a fixed clamping block 4 for resisting and clamping, a second vertical platform 5 is fixedly installed at the other end of the top of the device base 1, the heights of the first vertical platform 2 and the second vertical platform 5 from the device base 1 can meet the use requirements of the frame rotation, a reciprocating mounting block 6 is installed on the top of the second vertical platform 5, a rotatable second rotating shaft 7 is connected to the middle part of the mounting block 6, and a movable clamping block 8 for resisting and clamping is fixedly connected to one end of the second rotating shaft 7 close to the fixed clamping block 4, and the movable clamping block 8 is aligned with the fixed clamping block 4. The first vertical platform 2 is provided with a vertical slide groove 18 in the middle of a side close to the second vertical platform 5, and a second threaded rod 19 is rotatably connected inside the vertical slide groove 18, and a third rotating wheel 20 is fixedly connected to the upper part of the second threaded rod 19, and a sliding block 21 is threadedly connected to the surface of the second threaded rod 19, and a supporting plate 22 is rotatably connected to the upper part of the first vertical platform 2 close to the second vertical platform 5. Through the setting of the supporting plate 22, the frame components can be effectively placed between the movable clamping block 8 and the fixed clamping block 4, and two supporting adjustment rods 23 are rotatably connected between the bottom of the supporting plate 22 and one side of the sliding block 21, so that the supporting plate 22 can be effectively adjusted to be removed from below the movable clamping block 8 and the fixed clamping block 4 to facilitate the rotation of the frame;

[0016] When in use, the frame component is placed on the top of the supporting plate 22 and located between the movable clamping block 8 and the fixed clamping block 4. When the frame component is clamped and fixed between the movable clamping block 8 and the fixed clamping block 4, the second threaded rod 19 of the third rotating wheel 20 is rotated by rotating the third rotating wheel 20. The rotation of the second threaded rod 19 will cause the sliding block 21 to move downward on its surface. The downward sliding block 21 will pull the supporting plate 22 to rotate through the two supporting adjustment rods 23, so that the supporting plate 22 is separated from the frame component and removed from under the movable clamping block 8 and the fixed clamping block 4, so that the frame component fixed between the movable clamping block 8 and the fixed clamping block 4 can be effectively rotated.

[0017] A horizontal slide groove 9 is provided on the top of the second vertical platform 5, and a first threaded rod 10 is rotatably connected inside the horizontal slide groove 9. A moving block 11 is threadedly connected on the surface of the first threaded rod 10. The mounting block 6 is fixedly mounted on the top of the moving block 11, and one end of the first threaded rod 10 is fixedly connected to a first rotating wheel 12, so that the mounting block 6 can be effectively moved and adjusted;

[0018] By rotating the first rotating wheel 12, the first threaded rod 10 is rotated, and the rotation of the first threaded rod 10 causes the moving block 11 to move on its surface and drive the mounting block 6 to move. The movement of the mounting block 6 causes the second rotating shaft 7 and the moving clamping block 8 to move toward the fixed clamping block 4, so that the moving clamping block 8 cooperates with the fixed clamping block 4 to clamp and fix the frame component.

[0019] A worm wheel 13 is fixedly connected to one end of the second rotating shaft 7 away from the movable clamping block 8, a worm 14 meshing with the worm wheel 13 is rotatably connected to one side of the mounting block 6, and the worm 14 can adjust the rotation of the worm wheel 13, a second rotating wheel 15 is fixedly connected to one end of the worm 14, a 360° angle scale 16 is fixedly connected to the other side of the mounting block 6, and a scale pointer 17 aligned with the 360° angle scale 16 is fixedly connected to the surface of the second rotating shaft 7, so that the angle of the frame can be effectively adjusted;

[0020] When the frame component is fixedly clamped between the movable clamp block 8 and the fixed clamp block 4 and the welding angle of the frame needs to be adjusted, the worm 14 is rotated by the second rotating wheel 15, and the rotation of the worm 14 transmits the worm wheel 13 to make the second rotating shaft 7 drive the movable clamp block 8 to rotate. At the same time, through the rotatable first rotating shaft 3, the movable clamp block 8 and the fixed clamp block 4 can drive the clamped frame component to rotate to adjust the angle; and the rotation of the second rotating shaft 7 will drive the scale pointer 17 to rotate, and the rotation of the scale pointer 17 can accurately adjust the angle through the 360° angle ring ruler 16.

[0021] The clamping device for automobile frame welding has a function of precise angle adjustment after clamping, which can eliminate the need for repeated position adjustment and multiple clamping operations during frame welding, thereby effectively improving the convenience of welding operation and improving the quality of welding.
