After the piston rod of the clamping cylinder 3 extends into the fixing seat 1, it is connected to the left rotating arm 6 and the right rotating arm 8 through a synchronous rod 10. When the piston rod moves, the synchronous rod 10 drives the left rotating arm 6 and the right rotating arm 8 to move, and the left rotating arm 6 and the right rotating arm 8 act on the left rotating rod 4 and the right rotating rod 5 respectively, and then the left rotating rod 4 drives the left clamping jaw 7 to rotate with the left rotating rod 4 as the axis, and the right rotating rod 5 drives the right clamping jaw 9 to rotate with the right rotating rod 5 as the axis.

[0032] Through the above structural design, the clamping cylinder 3 can drive the left rotating arm 6, the left clamping jaw 7, the right rotating arm 8 and the right clamping jaw 9 to rotate.

When the piston rod of the clamping cylinder 3 acts on the left rotating arm 6 and the right rotating arm 8, taking the left side as an example, the left rotating arm 6 drives the rotating shaft 401 to rotate through the limit pin 402, and the left clamping jaw 7 on the rotating shaft 401 rotates synchronously with the limit pin 402 and the rotating shaft 401. Therefore, the left rotating arm 6 can act on the aluminum rod 13 together with the left clamping jaw 7.

[0034] Preferably, the rotating seat 403 includes a cover plate and a base, the cover plate is provided with a plurality of mounting holes, the mounting holes are provided with screws connected to the fixing seat 1; the base is fixedly provided on the cover plate, and is provided with a slot that matches the rotating shaft 401.

Multiple clamping points can effectively increase the contact area during clamping, and the stability when clamping the aluminum bar is better.

[0036] Preferably, the left clamping jaw 7 has the same structure as the right clamping jaw 9, and the left rotating arm 6 has the same structure as the right rotating arm 8; the lower parts of the left clamping jaw 7 and the left rotating arm 6 are respectively provided with arc-shaped clamping grooves 701 that match the aluminum rod 13. In this embodiment, the clamping jaws and rotating arms on both sides adopt the same structure, which can reduce production costs and facilitate installation.

Through the above structural design, when the clamping cylinder 3 works and clamps the aluminum rod 13, the photoelectric sensor sends a signal and receives feedback, indicating that the entire aluminum rod 13 clamping device is in a normal working state; when the clamping cylinder 3 is actuated, if the photoelectric sensor fails to receive a feedback signal, it indicates that the aluminum rod 13 is not detected, and the alarm sends a signal to the outside to remind the staff that the aluminum rod has not been clamped, so that the staff can intuitively understand the clamping status of the aluminum rod, so as to proceed to the next process or respond quickly to the on-site situation.

[0042] Compared with the prior art, the utility model has the following beneficial effects: the single-cylinder aluminum bar clamping device of the utility model acts on the left rotating arm and the right rotating arm through the clamping cylinder, and then drives the left rotating rod and the right rotating rod to rotate, and then the left rotating arm, the right rotating arm, the left clamping claw and the right clamping claw clamp the aluminum bar together.
