At the center of one end of the fixing plate 1, a cushion block 2 is fixedly connected. A first push rod 3 is fixedly connected to the cushion block 2. The upper end of the first push rod 3 is fixedly connected to a support block 4. The first push rod 3 can drive the support block 4 to move in height. At the same time, a driving motor can drive a rotating rod 5 to rotate. Thus, when the main vacuum suction cup 7 cooperates with the auxiliary vacuum suction cup 23 to adsorb the sheet metal part body 15, the rotation and height movement of the sheet metal part body 15 can be realized. One end of the support block 4 is fixedly connected with a driving motor and the output end of the driving motor is fixedly connected with a rotating rod 5. On the side of the rotating rod 5 away from the support block 4, a support disc 6 is fixedly connected. A main vacuum suction cup 7 is fixedly connected to the support disc 6. On four sides of the support disc 6 away from each other, a support bracket 22 is fixedly connected. An auxiliary vacuum suction cup 23 is fixedly connected to the support bracket 22. One side of the fixing plate 1 is fixedly connected with a support bar 8. On the side of the support bar 8 close to the first push rod 3, a second push rod 9 is fixedly connected. The first push rod 3, the second push rod 9 and the third push rod 13 are all electric push rods. The output end of the second push rod 9 is fixedly connected with a moving frame 10. On one side of the moving frame 10, a driving motor is threadedly connected and the output end of the driving motor is fixedly connected with a screw rod 11. A moving strip 12 is threadedly connected to the screw rod 11. The second push rod 9 makes the moving frame 10 move, which can push the moving strip 12 and the knocking plate 14 to contact the warped part of the sheet metal part body 15. The upper end of the moving strip 12 is fixedly connected with a protrusion and the bottom end of the protrusion is fixedly connected with a third push rod 13. A knocking plate 14 is arranged at the bottom end of the third push rod 13. The third push rod 13 can drive the knocking plate 14 to knock the warped part of the sheet metal part body 15 through telescoping. The bottom side of the knocking plate 14 contacts the sheet metal part body 15.

[0018] Wherein, the sheet metal part body 15 is fixedly connected to the bottom end of a buffer ring 16. The buffer ring 16 includes a spring telescopic rod. The buffer ring 16 is sleeved on the protrusion. The protrusion is fixedly connected to the bottom end of the third push rod 13. By arranging the buffer ring 16, buffering can be provided for the bottom end of the third push rod 13.

[0019] Wherein, a support plate 21 is slidably connected to a clamping frame 20. The clamping frame 20 is fixedly connected to one side of the fixing plate 1. The fixing plate 1 contacts the bottom end of the sheet metal part body 15. A pressure rod is threadedly connected to one side of the clamping frame 20, and the end of the pressure rod contacts the support plate 21. By arranging the clamping frame 20 and the support plate 21, support can be provided for one side of the sheet metal part body 15 on one side of the fixing plate 1.

[0020] Wherein, a fixed sleeve 17 is fixedly connected to one side inside the moving frame 10. The fixed sleeve 17 is sleeved on an inclined rod. The inclined rod is fixedly connected to one end of a cushion plate 18. The cushion plate 18 contacts one side of the sheet metal part body 15. By arranging the fixed sleeve 17, the inclined rod and the cushion plate 18 in cooperation, the cushion plate 18 can be made to contact the other side of the sheet metal part body 15.

[0021] Among them, a positioning rod 19 is inserted into the diagonal rod, and the positioning rod 19 is threadedly connected to the fixed sleeve 17. By setting the positioning rod 19, the distance between the diagonal rod and the fixed sleeve 17 is limited, thereby providing a supporting effect.

[0022] Working principle: Vertically attach the sheet metal part body 15 to the main vacuum suction cup 7 and the auxiliary vacuum suction cup 23. At this time, the bottom side of the sheet metal part body 15 contacts the fixed plate 1. Then, adjust the support plate 21 to move upward and limit it with a pressure rod. At this time, the support plate 21 contacts one side of the sheet metal part body 15. Then, the second push rod 9 drives the moving frame 10 to move closer to the sheet metal part body 15. Adjust the pressure rod so that the backing plate 18 on the diagonal rod contacts the other side of the sheet metal part body 15. At this time, start the drive motor on one side of the moving frame 10 and drive the screw rod 11 to rotate, and make the moving strip 12 and the third push rod 13 at the bottom of the protrusion drive the percussion plate 14 to strike the edge of the sheet metal part body 15. Then, the drive motor on the support block 4 drives the rotating rod 5 and the support disk 6 to rotate, thereby changing the contact surface between the sheet metal part body 15 and the fixed plate 1, and cooperating with the first push rod 3, it can greatly improve the adaptability of the straightening device to the sheet metal part body 15.
